Yes, My Mineral Collection Catalog (MMCC for short) is free of charge for you to use for an unlimited time. There are no ads and just some minor restrictions
as explained in the User License Agreement that you must accept before installing the software (and can still read in the Help menu): not for sale, no internal
modifications, no warranty, and so on.
|
There are two essentially different ways:
1. By creating an independent virtual machine that insulates a Windows box on your macOS or any Linux distribution (Android is based on the Linux kernel, after all). Within this box, you will be able to
run any Windows program on your computer the same way you would do it in the native Microsoft operating system. You can easily have such a virtual
machine working by just installing VirtualBox on your system, which is a free product from Sun Microsystems. Please go to the
VirtualBox site to get more info and download the
software. Parallels Desktop and
VMware Fusion, designed specifically for macOS at the time of writing this, also create hardware
virtualization for running Windows software on your computer.
2. With the help of Wine or
CrossOver, which act as an intermediate layer to encapsulate a Windows
environment. Wine is free of charge and works fine but is not perfect yet, so expect to see rather old-fashioned buttons and some odd
color tones, and probably the internet links not working. But the application's main functions should operate properly.
|
Absolutely not. The installation process neither erases nor overwrites the user's files. Several example records included in the pack are only copied when
there is no data at all, typically during the first installation.
Please also carefully read question #7.
|
|
The pack that is distributed from this site is warranted to be virus, trojan, adware and spyware-free. And if you finally stop using it, you will be able to perform a clean uninstallation.

The screen must be able to work with a width of at least 1280 pixels and a height of at least 1024. Smaller sizes may truncate some of the MMCC forms. If you need to change it, close all the applications that may be running, place the mouse pointer near the center of the screen, make a click with the right button to open the Properties dialog, select the Configuration or Settings tab, and set the screen resolution to at least 1280 pixels wide and 1024 pixels high.

I strongly recommend performing them on a drive other than the one where the program is installed. It can be either a second local drive (HDD or SSD),
internal or external, a network drive, a USB flash memory stick (pen drive), or an SD card, in order to prevent losing your data in case of mechanical or logical failure of the
drive where the application and the user files actually are. Never create backup copies on the same drive where MMCC is installed. From time to time, also copy your data files to
your smartphone via Bluetooth, Wi-Fi using FTP, on-the-go pen drive, email attachment, or whatever way you prefer. If you don't mind other people snooping on your data, send your
backup copy to the cloud. But don't believe that lie. The cloud does not really exist; it is just someone else's computer.

Unfortunately, the answer is no. There is no possibility of importing data from other formats unless you are able to convert it to
Paradox with the same field structure that MMCC uses. Not an easy task if you are not an expert
in database management and lack the tools to do it. Developing a standard procedure to automatically perform that kind of operation is quite difficult, highly time-consuming,
and must be done on an almost case-by-case basis, given the number of existing formats and, above all, the multiplicity of field structures each one can have.
|
Those rates are by default the ones of Catalonia, where MMCC is being developed.
But you can easily edit all of them by opening the inflation database file (menu item File > Inflation rates) and overwriting the existing values. Then click on the menu
item Utilities > CPI adjustment for the field Current cost of every specimen to be recalculated. When the rate of a new year has to be added, just open a new record
by pressing the down arrow in the last line of the main data grid, enter the year and the rate, and repeat the recalculation. Go to the website of your local government to
get the real inflation data recorded in your area.
See also question #10.
|
As explained in the previous question, this function makes a full recalculation of the field Current cost, on a record-by-record basis, to adjust them for inflation. It only needs to be run once when some change has been made in the inflation database; otherwise, the prices will be recalculated but not changed.
See also question #9.
|
As you surely know, the specimen database file can be ordered by different criteria, and that order is saved in several auxiliary files technically known as index files. In certain circumstances, they can get corrupted, and then the reindex function comes to the rescue by simply rebuilding them. You don't usually need to perform this operation unless you notice some strange behavior when ordering the records or an error message (something like Index is out of date) is shown after opening the database files. You can choose between a regular and a clean reindex (this one works by deleting the preexisting index files). Any reindex operation also rebuilds the index files linked to the species, contacts, and inflation database files.

Firstly, open the Help > About box and write on a piece of paper the name of both the Data and Backup copies folders (or just get a screenshot). Then make sure to close the application and copy all the files from the folder where the Backup copies are to the Data folder (be very careful not to perform this operation in the opposite direction). Allow them to overwrite each other. Open the MMCC again. Everything should work fine.
Note: Your backed-up files will actually be found within a folder with a name equal to the year, month, and day that they were done, separated by a hyphen, inside another folder called Minerals.back. Copies made on the same day are overwritten. You will typically want to restore the most recent ones, but if this doesn't work, do it with the immediately previous ones, and so on.

Yes, just click the field column title. If the field accepts normal and reverse order, try to click a second time. But if the field cannot be ordered, this operation will do nothing.
|
|
Drag the title with the mouse to move it. To change the width, put the cursor on the title, just over the right border, and drag left or right. The new positions of the columns, if moved, are not persistent after opening the application again, but the new widths are kept for further sessions.
|
|
All these settings, main data grid column widths included, are written in the configuration file minerals.ini, which can be found in the App folder
(provided you execute MMCC as an administrator). To reset them, first, don't forget to close the application and then delete that file. In Windows 7, 8.1, 10, and 11, look for
it in the deep folder \Users\[UserName]\AppData\Local\VirtualStore\Program Files (x86)\Minerals, where [UserName] is, you guessed it, the name of the user on Windows (if you
installed the application in a different folder, change that path accordingly). However, you may need administrator permissions to open it.
|
The first cost is the amount you paid for the specimen at the moment of purchase. The latter means this same cost has been adjusted for the inflation that
has been registered since then. It can be quite useful, especially with pieces bought many years ago, to get an idea of how much money they would be equivalent to today.
See also question #28.
|
|
Go to the Preferences form and leave the Title box empty. The entire panel will become invisible.
|
Before opening the print reports screen, widen or narrow the main grid columns you are interested in. You can also move columns out of the screen to get them excluded from the report, and switch their position to get this position also changed in the printed report. Read also question #14 for details on how to move and widen columns. Other options are changing the font size or the printer orientation.
|
Just set a filter before opening the print reports function, or select the rows you want to include in the report. Read question #20 for more details.
|
|
Hold down the Control key and click each of the rows you want to select. If the rows are contiguous, hold down the Shift key with your left
hand and press the up or down arrow key with your right hand. Combinations of both procedures can also be used. Just try it and get some practice. The selected rows will be
highlighted in blue and will have a dot visible in their left margin. This operation may be useful for having a printed report restricted to only certain records, and for
summing up the cost, the mass, and the appraisal value of a number of selected records. Try it out for yourself!
|
|
Check the Preferences form. The Photos & videos folder may be wrong, or somebody may have renamed it or deleted the files inside.
|
The actual field in the physical file has room for 12 characters. And it seems they are enough. There is no need to write Lao People's Democratic Republic or People's Republic of China if you can write just Lao or China, or United States of America and United Kingdom instead of the more common USA and UK. You can even enter an acronym or abbreviation that you like or find to be more mnemotechnical, since a country may have other meanings. For many people, it must not necessarily be a nation-state because there are territories that can also be considered countries without having that rank.
|
|
Given that that information is common to all specimens of a single species, it seems redundant to repeat it in each record. If you own fifty pyrites, were you
going to include in your file such an amount of data multiplied by fifty? This is nowadays an inefficient way of storing information and may even be a waste of time as well. I
think that you should never include any detail in your catalog that is already easily found on the net or in any reference book. As you may know, the program puts at your
fingertips specific direct links to the major mineral databases on the internet, which can provide you with all of that and much more in a matter of seconds. Try to click on
the button next to any of the species fields in the Edit form, and a page of related data will be opened. For free!
|
|
Yes, you have three user-definable fields available. Just go to the Utilities > Preferences menu and give them the names you need.
|
The maximum length is shown in parentheses after every field name. The fields whose type is string (aka character or alphanumeric) are Number/ID (8),
Species 1/ Specimen's name, Species 2, Species 3, Species 4, Species 5, Species 6, Species 7, and Species 8 (25),
Description (200), Location (10), Locality (120), Country (14), Provenance (75),
Condition (12), Rating (2), Label price (9), Buy price (9), Size (30), Largest crystal (60),
minID (7), Appraisal by (50), Free field 1 (60), Free field 2 (60), Free field 3 (60),
Images and videos (64). Acquired, Appraisal date and Last edit are of date type. Original cost, Current cost and Appraisal value are currency.
Mass is numeric (float type) with two decimal places. Marked is logical (Boolean). And the type of Notes is memo, a field that contains plain text (text
without formatting), the field size being very large (maybe up to 256 MB).
|
It's not something the user can tackle on their own. Not only would the application have to be internally modified and recompiled, but the structure of the
actual Paradox file that contains the data (whose name is minerals.db) would have to be
changed too on every computer where it resides.
|
|
Object Pascal, along with several third-party tools, mainly RX Library (Fedor Koshevnikov, Igor Pavluk, and Serge Korolev), and GLAD Components (Greg Lief).
|
There are two major differences between them. Label price can be defined as the labeled price, the price at which the specimen was tagged when it
formerly had been for sale, and Buy price, the price really paid after shipment expenses and a discount, if any. A switch of currency is now frequent, so you can buy, for
instance, in euros but your credit card may be finally charged in dollars, which will be the Original cost. In any case it may be interesting for many collectors to keep
record of what the Label price and Buy price were at the moment of purchase.

They are named MINERALS and DELETED, with the extensions DB, MB, PX, X??, and Y??; INFL, with the extensions DB and PX; SPECIES,
with the extensions DB and PX; FILTER.DB; and MINERALS.INI. But don't worry about the risk of losing them, if you take care of making backup copies every time
you close MMCC; all these files are included in the backup function, so every time you execute it, they are copied to the folder you set in the Utilities > Preferences menu.
See also question #94.
|
You can either set a filter by clicking on the menu item File > Filter, or manually select the records you want. To know how to have records selected, please read question #20.
|
There must be some damage to the data, or more likely, to the index files. But they can usually be repaired by performing a Regular reindex, as explained in question #11. If the problem keeps going, do a Clean reindex. If the anomaly persists, however, close the application, open it again, and repeat the reindex operations. As a last resort, you will have to restore the most recent backup copies.
See also question #11 and question #57.
|
|
This can be done at any moment by pressing the Control+S key.
|
|
Yes, you can type any character, number, uppercase letter, dot, hyphen, slash, even blanks, etc., except lowercase letters.
|
|
If you mean hidden, the answer is no in the Edit form (except the field Notes), but yes in the grid of the main screen. To hide a field in that grid, drag to the left as much as you can the column's right border by placing the mouse cursor on the title. Do the opposite to make it visible again. This state will be kept for future sessions of the program.
|
|
Of course. Just perform two installations of the application in independent folders. But you will not be allowed to have both programs open
at the same time to keep from getting the data corrupted or your computer hanging. For your convenience, you can create a shortcut for
each installation on the desktop.
|
Terminate or close the application the way you can (I suggest Windows Task Manager by pressing the keys Control+Shift+Esc), then search the program folder for files whose name are Pdoxusrs.lck, Paradox.lck and Pdoxusrs.net, and delete all of them. Then try to open the application again.
See also question #49 and question #101.
|
|
Just go to Utilities > Preferences and leave the free field name(s) blank.
|
|
That's not a bug. The field Number/ID is not really numeric yet alphanumeric. This means you can write in all kinds of characters, digits, uppercase letters, punctuation signs, etc., even spaces, except lowercase letters. Therefore, the digits are considered just as characters, so the number '2' follows the number '11' for the same reason that 'B' follows 'AA'. If you are going to use only digits, you'd better write the Number/ID with leading zeros, for instance, '001', '002', '003' and so on.
|
Please also read question #52 before deciding if having simple labels is enough for you.
It is not as straightforward as it appears. Implementing a complete and flexible function to have labels printed is not a matter of a couple of days' work because not only the
fonts should be controlled. In addition to fonts, there are a lot of other parameters to take into account. Paper size, column number, column width, label height, position of
the fields, what fields to include, inserting a graphic logo, drawing frames, and so on. And all of them must be hard-coded. I'm sorry, but currently I don't have enough time to
develop such a function.
A good alternative, however, might be to export the data in MS Excel format and get the labels there. Or transfer the data from MS Excel to MS Access, which
has several functions to print out outstanding stuff. For the exporting function, see question #56.
|
Just delete those records the usual way, and the app itself will copy them to another file. You will still be able to see and manage them by clicking on the menu item
File > Removed. But if you delete one of such records again, it will be lost forever. In case of a mistake, however, you can also restore immediately the most
recent backup copy (if you have one) of the files whose name is deleted with any extension. Think of the Removed files as if they were a trash bin.
See also question #12.
|
The application has no function to recover a deleted record. The easiest way is to open the Edit form of the record after clicking on the menu item
File > Removed. Then click on the Single record report button, and you will get a text file with the content of all the fields. Then manually register the
specimen again. It's not a lot of work anyway. Or you can restore the most recent backup copy.
See also question #12.
|
|
It has no predefined function, it's up to you. You can mark the records of the specimens you most prefer, or the pieces you plan to remove in the near future,
and so on. It can also be useful to manage two parallel collections in the same app. The main (not marked) and the duplicates or a specialized collection (marked). The marked
records will be displayed in a red font on the main grid.
|
This is an issue that may arise in rather rare situations. Ignore any error messages and then try a Clean reindex. You will eventually recover all your data.
See also question #31.
|
|
Some collectors prefer to give every specimen a name of their choice that is different from the main species'. So you can use that field to store either the main species or the specimen's name you have assigned to the piece, if any.
|
|
Because of the way the Mindat locality database works, if you launch a search with the full locality name, you are not going to get any results most of the time. It is better to highlight (by dragging the mouse) a key piece of text rather than the entire locality. Also, try double-clicking a single word.
|
|
No, it's not. When developing that function, I thought about it for a while, but finally decided it made no sense. If some years ago someone made an appraisal for you, the specimen's adjusted for inflation value is not necessarily equal to the value your specimen has in the market today. Just an example. In 2016, you purchased a good Daoping pyromorphite for $3,000. Given the fact that the mines are now exhausted, the current value of the specimen might be double of the original, no matter what the inflation rate is. The opposite may also be true with other specimens.
|
|
If you activate it, when creating a new record, the application will assign the field Number/ID by incrementing by one the number of the last record added (this applies only when the last character is a digit).
|
|
To track the photos, the database stores only the image file's name. And that string is not updated when you delete (or move) a photo, since this is an operation
that is performed from outside the program. So the deleted (or moved) images will no longer be displayed in the records because the application will be unable to find them.
|
Make sure the program is really closed and open the folder where it is installed. Then delete all the files with the names pdoxusrs.net, pdoxusrs.lck and paradox.lck, and try to open the application again. Sometimes a reindex must be performed.
See also question #36 and question #101.
|
|
This probably happens because you are installing the program while a previous version is open. Abort the installation operation, be sure to close the application,
and start the installation again. If the problem persists, reset your computer and try the installation again.
|
|
It is the day when the photo was shot, last modified, or downloaded from the net (email server included), the latest of them.

Try this:
1. On the main screen, move to the right by dragging the mouse all the grid columns other than Species/Name, Locality, and Country until all of them are placed on the right side of the screen. Read also question #14 for details on how to move and widen columns.
2. Make the Country column wider than usual with the mouse in order to push to the right the unwanted columns that still remain visible until all of them are hidden.
3. With a click, select or make active the line of the specimen you want a label from.
4. Make sure the only visible columns are the ones you want printed.
5. When you are done, open the menu option File > Reports & Labels, or press Control+R.
6. Leave Page title and Page numbers unchecked.
7. Set Number of copies to 1 and Lines separation to 10.
8. Check Records in Page layout.
9. Check Current row in Rows.
10. Check Visible columns in Columns.
11. Click the button Grid data in Font and select any font you like.
12. Click the button Print to have the label printed.
13. Finally, you may want to reset the grid column order, width, and position to the factory settings by clicking on the menu item Utilities > Reset Columns.
- You will get a printout with two columns. Discard the left one. There will be a simple label for your specimen on the right.
- Make some tries by setting different line separations and grid data fonts, or changing the columns width and position, until you get the best result.
- If you don't like the country printed, just hide this column the same way you did with the others.
- If you want the Number/ID, Description, or another field included, make the corresponding column(s) visible.
- To print more than one label in one single operation, try either to set a filter or to select multiple rows (read also question #20 for details). Or do nothing if you want to print one for every specimen. Then change the setting in step 9 accordingly.
- If you need more sophisticated labels, however, read question #39.
|
|
The species file is intended to contain only approved species names. The variety can be included in the fields Description or Notes. But you can manually add new names to the species file and even translate them into your language if necessary.
|
Make sure you are logged into Windows as an administrator. If not, log in again in order to have all the administrative permissions. Then open the executable file Properties window (right-click either Minerals - Application file name, or minerals.exe file name, or the program shortcut on the Desktop). Then go to the Compatibility tab and check Execute (or Run) this application as an administrator (this may vary depending on your version of Windows).
Failing to do so can produce some system errors at startup, or, depending on the Windows version, your data files can be found at the folder \Users\[UserName]\AppData\Local\VirtualStore\Program Files (x86)\Minerals, where [UserName] is the name of the user logged on Windows.
See also question #74 and question #76.
|
Try to close the program. If you cannot, terminate it through the Windows Task Administrator. Open it again, go to the menu item Utilities > Reindex, and click on the Regular reindex button. If the problem keeps going, go for a Clean reindex, even a second time, until everything works fine. If you were not able to solve it this way, the latest backup copy will have to be restored, following the directions in question #12.
|
The user's files are in Paradox 7, which is not a rare format, but a function
is available in MMCC to easily export all your data to an XLS file. That file can be read and processed by other known software like MS Excel, MS Access, and the free and splendid suites
LibreOffice.org and OpenOffice.org. Important: You must have MS Excel installed on the same
computer for the export process to work properly. You will find such a function in the menu item Utilities > Export.
But if you ever want (or need) to directly open the Paradox tables, install a free
piece of software named Extended Database Desktop (xDBD32 for short) that you will find at
SourceForge. It's very intuitive and easy to use. Another
free and excellent utility for that purpose is Paradox Data Editor (PDE for short), which can be downloaded at
MiTeC.
|
The regular reindex operation just rebuilds the preexisting auxiliary index files. A clean reindex, however, physically deletes all those index files and then builds new ones from scratch. This second operation can be a lifesaver when a regular reindex is not enough to solve the problem because of the poor condition of the index files. Read also question #11 for more details.
See also question #11 and question #31.
|
|
Look for a button on the top area of the main screen that shows a magnifying glass, and click it. This is the Search button. Then enter the file name or just a portion of it and click the Next button. For higher efficiency, however, it is recommended to give the image files a name in such a way that the specimen Number/ID is included in it, for example, 1234-galena.jpg.
|
|
There is no general rule for doing that. But it is an excellent idea to name them by starting with the specimen's Number/ID, followed by a hyphen, and the
species name. If you have several photos of the same specimen, add a sequential number. For example, 1234-galena1.jpg, 1234-galena2.jpg...
|
The installation program is carefully instructed to never overwrite existing user data files, and I can't imagine any reason for this failing. Your data is
neither overwritten nor deleted. If somebody can't see them it's usually because the data is in another folder (not excluding the low probability that the
user inadvertently deleted them beforehand).
Let's see what to do now. Just after finishing the installation of My Mineral Collection Catalog, the app will be executed with administrator
rights, since this is required by Windows for the installation program to work. If MMCC had been running until now as a limited user, your data
files were moved by Windows to a different folder (typically C:\Users\...), an operation that is known as virtualization. I suggest you close the
program and open it again as usual, the installer aside.
Your data should be visible now. If not, you can make three operations to go on. (1) Make sure you have installed MMCC in the same folder as before,
not in a new one. (2) By using the Windows File Explorer, perform a search on your computer for a file named minerals.db, and
a list will be shown displaying the folders that contain it, its size, and the last date it was edited. Look for the one that has the most recent data and a larger size. (3) If there is not such file in a folder different
from the one where you installed the program, I fear something very odd has happened. The last resource is restoring the most recent backup copy.
See question #12 for more details.
Check the menu item Help > About to know the kind of Windows user you are working with and your actual data folder.
If you need more information about the administrator and limited users, please read also the question #74.
|
|
If such a name is included in the list, it must be because some record still contains it. Set a filter with the sentence Locality contains ... where the points are a specific text fragment from the full locality name you want to delete (File > Filter menu). The grid will now display only the record(s) for that locality. If not, check the filter setting or click on the button Magnifier to search all the database.
|
It is actually a consolidation of the Provenance field content of all your active records (not the removed ones).
See also question #84.
|
The best approach would be to install a VPN, or virtual private network, to get both computers linked through the internet. This would allow you to have
your data permanently synchronized in real time. If you don't like it, after finishing your work, get a backup copy of your files on a pen drive or an external hard (or SSD)
disk and then restore it on the other computer. See question #12 for the way to do it.
|
|
This most often happens because the image is too large, it is in PNG or BMP format, your computer is short
of memory or CPU speed, or too many programs are open at the same time. You can dramatically increase the opening speed by getting
a copy of your photos with a more manageable size, converting them to the JPEG/JPG format, closing the apps that clutter
the available memory, or, if all of this fails, by upgrading your computer.
|
|
Click on the menu item File > Sum up mass or press Control+W. This function is sensitive to filters and selected records set by the user, so you can
also get the value of just a subset of your collection, for instance, the ones that are only in a showcase if you filled out the Location field.
|
There is a solution to that problem in most cases. Try this:
1. Go to the Windows Start menu and type regedit in the Execute box, then hit Enter.
2. Scroll up on the left pane to make sure you are at the very top of the tree.
3. At the top menu, go to Edit, then Find and search for the word Display1_DownScalingSupported. Be patient, the process can take a while.
4. After right-clicking, change the value of Display1_DownScalingSupported you find from "0" to "1".
5. Then press the F3 key to make sure you change every found instance, because otherwise the hack won't work. There might be more than 10.
So you'll have to repeat steps 4 and 5 a number of times.
6. Once done, restart the system, and open My Mineral Collection Catalog again. It will produce a message and try to change the
resolution to the minimum supported, 1280x1024. If it failed to do so, this may mean your computer does not have that capability. Contact with
the manufacturer.
For advanced users, more details can be gotten by googling the keywords display1_downscalingsupported netbook together and other similar
combinations.

|
It's easy. Just set a filter like "Number/ID equals" and enter the specimen number or ID. Then activate the Gallery and slideshow.
|
|
The field Acquired is intended for storing the date you got the specimen, either purchased, from a gift, by exchange, or field collected. So I think you don't really need a specific field to keep track of the date you collected it. If you want to save more details, just use the field Notes or one of the free fields available at Preferences
|
|
Yes, you can move any column by dragging its title. And you can also make it wider or narrower. This is useful for getting printed reports. The new column position is not permanent, but the width is.
|
Make sure that you (1) are logged on Windows as an administrator, and (2) explicitly Run (the app) as an administrator. Both. Then repeat the reindex.
See also question #31.
|
This can sometimes happen in certain systems. But don't panic, and try this:
1. Close MMCC. If you can't, then open the Windows Task Manager (Control+Shift+Esc) and kill the program or end the task.
2. Open the app folder with Windows Explorer and sort the files by alphabetical order. Then look for a file with the name Minerals.exe or
Minerals - Application. Right-click that file and choose Run as administrator. If the program is opened as usual with your data and there are no error messages, you're done.
Otherwise, read the following lines to try another solution.
3. In the app program folder, carefully delete all files with the name minerals except those with extensions DB, MB, and EXE (maybe you will need to set your
Windows Explorer to not hide extensions of known file types). In case of a mistake, restore the deleted files from the Recycle bin.
4. Carefully delete all files with the name deleted, except those with extensions DB and MB.
5. Open the file minerals.ini with a pure text editor, like Notepad or WordPad, search for two lines that begin with Order=<here a number> and Invers=<here a number>, and delete both.
6. Save and close.
7. Open My Mineral Collection Catalog. You'll probably still get some message like No index currently active, but your data
should be there now. Dismiss it and jump to the next step.
8. First of all, go to the menu item Utilities > Reindex and click Regular reindex button.
9. Then open the menu File and click Removed.
10. Go to the menu item Utilities > Reindex and click on the Regular reindex button.
11. It's done. Just close and open MMCC again. No more errors should be displayed.
12. If you keep getting error messages, repeat the two reindex operations with the Clean reindex button instead.

Please follow first the recommendations of the question #87. If the problem persists, try this: Close MMCC, open the folder where it is
installed, and delete the configuration file minerals.ini (but do not empty the Recycle bin yet). Then open the application again and try double-clicking.
If the problem no longer shows up, check all your settings in the Preferences form. For the minerals.ini file location, see also question #15.
In some cases, the message Access violation may persist. This is a conflict in Windows searching for a memory position that no longer exists and is sometimes quite
difficult to resolve since there is no apparent reason. Try to do a reset of your computer and see if the problem keeps going. If so, create a new temporal folder, download the
MMCC installer, and run it in the new folder with the example records that are included. After opening the application, is the error message still showing? If so, it should be
triggered by something odd on your PC. If not, then it must be related to your data. Run MMCC as a limited user if you used to do it as an administrator, or the other way around,
and see if the issue keeps going. |
A primer to the Administrator/Limited rights mess:
1. As you may already know, according to Windows requirements, there are two kinds of users: Administrator and Limited, with different rights.
2. If you installed the application in the "\Program Files (x86)" or "\Program Files" folders, which is the default (but can be changed by the user
during the installation process), your database files can be either in the program folder (Administrator user) or in a deeper path (Limited user), as may be
\Users\[UserName]\AppData\Local\VirtualStore\Program Files (x86)\Minerals, where [UserName] is the name of the Windows user.
3. Since the user is free to choose between executing the application as Administrator or as Limited and switch it at any time, there is the possibility of unexpectedly
finding yourself with a database that is not the real one. But don't panic yet!
4. To make things worse, the process of installing must be conducted with Administrator rights for it to be able to write in the \Program Files folder.
No alternative. Windows rules.
5. When opening MMCC again, if it had been executed as Limited before, the data you will see may be different from what you expected. That is admittedly very annoying, but there is no
data loss, only that you have two sets of database files in different places on your computer.
6. To prevent this problem from arising, you should have the previous concepts very clear and then decide: (a) Either to execute the application as Administrator or as
Limited user, or (b) Either to install it in the folder "\Program Files (x86)" or in another. It's up to you.
7. In any case, it's crucial that you obtain a backup copy of your valuable data whenever you make changes. The application can perform it for you every time you close it
and will keep separate copies of every day at least for one year. Just give the order from the menu Utilities > Preferences. But select (if
possible) a different drive from the one where your working data is. For example, in a pen drive or an external HDD or SSD. Or in the cloud, if you prefer, but this may not
always be automatically accomplished. (Think also that there is no such thing as cloud computing; it is really sending your data to the computer of someone else.)
8. In the worst-case scenario of accidentally losing all of your data, you will always be able to recover the most recent files in a matter of minutes.
9. By opening the menu item Help > About in the application, you will know what kind of Windows user you are and where the real data folder is.
If you couldn't see them, you likely have an old version of MMCC, so just update it for free.
Please see more details in question #54 and question #76. And for more accurate help about this topic, you may want to contact the Microsoft support site.

It's longer than expected (60 characters) to make room for some details about the crystal. For example, 65 wide, 70 long, 35 edge, and so on. If the specimen
contains several species, you may want to add the size of the largest crystal of each as well.
|
1. If you are executing MMCC as Administrator (recommended), you will always keep your data files in the same folder where the app is installed.
2. If you chose to install the program in the \Program Files (x86)\Minerals folder (which is the default for Windows) AND execute it as Limited (also the default),
you will find your files in the deeper folder \Users\[UserName]\AppData\Local\VirtualStore\Program Files (x86)\Minerals, where [UserName] is the name of the Windows user.
3. You can easily find out where your data actually is and whether you are running the application as an Administrator or Limited user by opening the menu item Help > About.
4. To switch the execution of the program from Limited to Administrator please go to question #54.

Clear the third box of the condition you want to remove and click the OK button.

First, gather all your mineral pictures in one single computer folder. Then open the menu item Utilities > Preferences, go to the frame Folders,
fill the box Images with the path of the folder where you put your images, and click the OK button. Then open the Edit form of the specimen, click on any of the
boxes named Image, and select the image you want.

No, at the moment, there is no way to do it. But you can use two ways to meet your needs:
1. On the main form, click the button Search (with a magnifying glass), write the name of the species you want, and then click Next as many times as needed.
2. If you don't like this, click the button Filter (with a funnel) and define a filter with "Species #" — "contains" — the name of the species you want.
Then click OK. You can add as many Species # as you need to the filter conditions, then uncheck the All values required checkbox and optionally save the filter
conditions for future operations.

Just for you info, Blob stands for Binary Large Object. That said, this issue happens when the Blob pointer of the record in minerals.DB (the main database file) becomes
inconsistent with the one in minerals.MB (which stores the field Notes). This could occur when the writing to the DB file was successful but the MB file did not get updated, or vice versa, and
produces an asynchrony or mismatch between both files, which can be either caused by an accidental file corruption (computer fault) or an incomplete backup restore (user fault). Possible solutions:
If MMCC finally opens, go to Utilities > Reindex and try a Regular reindex. If it doesn't work, perform a Clean reindex.
If the application can't be opened at all, or all that's been said above doesn't work, restore the most recent backup copies; for more details, read question #12.
If this doesn't work either, I advise you to try a Paradox repair utility, as explained in question #95.

The field Notes only accepts plain text, a data type that does not support any formatting (bold, underline, italics, link, etc.). But to get around
this limitation, I have introduced a trick to facilitate such an operation. Just select or highlight the text with the URL (internet address) by dragging your mouse. The pop-up
menu will appear immediately with the item Open website. You will find something alike in the View "Notes" form available in the main data grid.

Simply update to version 4.1.5 or higher, where this issue has been fixed.

For some reason, the system on your device appears to be unable to recognize a path that is that long or has that name. Try to make the copies either in a less deep folder or with a different name.

A brief history of the specimen can be noted here. Note this if it was field-collected by you. If it was purchased, write down from whom. And you could also
write the names of previous collectors who also owned it, if any. Up to 75 characters; if it is not enough, you may want to write the remaining in the field Notes. To keep
the locality (the geographical point where the specimen was extracted from), use the Locality field instead. Very important information about the provenance of minerals can
be found in Daniel Trinchillo's articles at The Mineralogical Record, issue 46-2, page 212 ( Provenance: Its importance in Mineral Collecting), and issue 55-2, page
144 ( Historical Provenance).

It depends on your browser but, in most cases, you can press the Control+F key and enter the string or words you want to search for. This works at least with Firefox, Google Chrome and MS Edge.

I don't recommend doing it because this document is updated over time often, and is available online 24/7 by just pressing the F1 key from inside MMCC, letting aside ecological issues with paper, energy, and toner (or ink) consumption. But if you believe it is necessary, press the Control+P key here and go ahead. I think it works with almost all browsers.
An alternative that is more eco-friendly would be printing it as a file, so you can always read it offline. After pressing the print key, the browser will open a dialog where you can select Destination: Microsoft Print to PDF (depending on your browser and operating system).

This bug has been cleared in version 4.2.3. So just download that release (or higher) and install it. If the message keeps showing, read the question #73.

I'm sorry, but such a delay is necessary. Its duration is directly proportional to the number of records in your database and inversely to the speed of your computer, which depends on a number of elements, some related to hardware and others to software. However, you can suppress the delay right away by unchecking the Autocomplete text in the Preferences form, but then you will lose the function to select from a list the Locality and Provenance among the pre-existent ones.

Firstly, take note of the Data folder name in the About box. Then close MMCC and open Windows Explorer, go to such a folder, look for files
which name is Species with several extensions, and delete carefully all of them (there are typically only two). Finally, open My Mineral Collection Catalog again,
and you will find the species database empty, ready for you to add the data you want.

Looking at the not-distant future, the huge database Mindat is implementing a universal and unique code to
be associated with each existing mineral specimen in the collections (or stored for sale) around the world. The minID format is AAA-AAA, where A is any letter or digit,
except for B, I, O, S, and Z (the code is not case-sensitive, and the hyphen is not mandatory, just for clarity). This allows them to have up to 31 6 (887,503,681)
different combinations, so they can expect to have enough room for a long time ahead. If you have already posted at least one photo of your specimens at Mindat, you may
already know what their minID is. But even if that is not the case, you can ask them to create one for
any or all of your pieces. In addition, you will have for your convenience a direct link from a given specimen in MMCC to the corresponding page at Mindat (if you have any).
To learn more about this topic, go to the introductory page and read the
Mindat FAQs.

This can be solved in only a couple of minutes. Just download the installer and run it. Not only you will get rid of such annoying message,
you will enjoy of new functions and fewer bugs too. Don't worry about your data, it is safe provided that you obtain a backup every time you close MMCC.
See question #60 for more details.

Look for an arrow with a triangular shape on the right border, next to the eighth image box. Click it, and you will have access to the 8 missing images.
That arrow can have two colors: gray when there is no image on the other side, and red when there is at least one.

It is protecting your data from any accident. MMCC can be reinstalled any time you want, but your data is unique. Go as soon as possible to the
Preferences function and fill in the box Backup copies. Then click on the Perform backup on close checkbox. And don't forget to read critical
question #7. That's all.
Think that you, the user, are the only one responsible for keeping your data safe. So back up your files regularly; otherwise, you could lose crucial data if your HD or SS
drive ever fails, which is just a matter of time.

For those who don't know yet, Paradox is the format of the My Mineral Collection Catalog data files. And yes, there are several free utilities
that allow you to successfully repair corrupted Paradox tables, including the error that triggers the annoying message Blob has been modified
(read question #80). Just open the page
AJPDSoft (in Spanish) and download the
Borland Utility Dtutil32. Another site where you can also get this kind of applications for free is
Qtools Software. Or search the net for TUtility Paradox or something alike.
Those utilities work well almost of the time, but since I cannot guarantee success, please make sure to run it after getting a backup copy of your files
(read question #12) or, if MMCC couldn't be opened, in a folder that is a copy of the original.

There are a lot of options for you to choose from:
1. Double-click the line on the main grid (this is my favorite).
2. Press the Enter key.
3. Press F2.
4. Select the menu item File > Edit.
5. Click on the Edit button in the upper toolbar.
|
|
If you have the version 4.3.0 or higher (you may check it in the About MMCC box), go to Preferences and click on the Default button
that is found inside the Grids group box. If you don't have such a version yet, just download the app installer and update it.

This typically happens because of the cache memory of your browser. To save time and net traffic, it takes the installation pack of the most recent version you
downloaded, which keeps hidden somewhere on your computer. In such cases, you should manually clear the browser cache. But in case you don't know how, and since each browser has
its own way to clear the cache, you may want to search the net for something like how to clear cache memory in [my browser]. Or try another browser. Or repeat the MMCC
update a few days later to allow the memory cache to be cleared automatically (this happens too 😊).

As you may know, either the Tab or Enter keys can be used to jump to the next field box when you're editing a record or filling in a new one
in the Edit form. You can skip the fields you (almost) never fill with this setting, saving some time.
|
Yes, I know there is currently (at least) one. However, it is quite intricate.
You set a filter in the main grid with any of the conditions 'contains' or 'does not contain'. Then you open the Edit form and modify the content of any
fields. If you either neglect or don't take care to click on the Save button before skipping to any next (or previous) record, the changes won't be saved.
I'm dealing with it, but it's not easy, and I'm not sure to work it out anytime soon because it depends on some complex external routines.
Good news: This bug is not there anymore. For your data safety, just download and install, as soon as possible, the app version 4.3.3 or higher.

Close MMCC the usual way and delete the files Pdoxusrs.lck and Paradox.lck in the folder C:\Users\John\AppData\Local\Temp. John is only the user's name, so it
will be different on other computers.

I can offer you two solutions: enter the first day of the year instead, or leave that field blank and append the year to the field Number/ID, as either
a prefix or a suffix, separated from the old code with a hyphen. Doing it as a prefix has the advantage that you will be able to sort your records by chronological order, or the reverse.

According to reliable data available on the net, a Paradox table can accommodate up to two billion records, but the file size is limited to 2 GB.
Taking into account the more restricted limit of the file size, it means over 700,000 records. Too high to be surpassed in all your lifetime as a mineral collector, unless you
are the curator of a large museum or a very rich person. Just for your peace of mind, I am aware of users who have near 5,000 specimens and have yet to report any
issues. But if MMCC is too slow to process your data because there are too many records, check how much RAM and CPU speed your computer has and upgrade it if needed.
How to know how many records you have in the larger file, which is usually the one that is displayed in the main grid: Look at the status bar in the right bottom corner of
the main screen, and you will see two numbers separated by a slash. The second number indicates such a value. If the database is filtered, just clear the filter.
Note: The data files are those in the Data folder that you can find under the menu item Utilities > Open.

The field Last edit was added in version 3.8.0 (April 24th, 2022). Thus, the last edit date of any record that was modified with an older version was
not recorded in the database. And any change made with version 3.8.0 or higher must be shown. Please check it out.
|
|
For this functionality to work, you must have MMCC version 4.0.6 or higher and Windows version 10.0.22621.1413 or higher. If not, update them as needed.

Sorry, but such a field is of numeric type, so it only accepts digits, one decimal separator, and the minus sign (-) at the front.
