INFO: Visual Basic 4.0 File Types & Version Control Recommendations

MORE INFORMATION

Project Files

The following file types make up your Visual Basic version 4.0 project and are automatically pulled into your source code controller if you specify:

   .frm, .frx - form
   .bas       - visual module
   .cls       - class module (new in Visual Basic version 4.0)
   .vbp       - project make file (same as the .mak file in earlier
                versions)
				

When a form is first added to a project and saved, the .frm file is created. The .frm file is a text file that contains the source code for the form along with information about the positions and properties of the controls on that form. Once any graphic controls (such as a picture box or grid) are added and the form is saved, the .frx file is automatically created to hold the binary information about the graphic controls. It is very important that both files are controlled together -- checked out and in together -- even though the .frm file is text and the .frx file is binary.

The following additional file types may also be a part of your Visual Basic version 4.0 project. You should add these files manually to SourceSafe so they can be controlled, especially if they are customized:

   .ini       - initialization file (for 16-bit applications only)
   .bmp, .ico, .rle, .wmf, .emf, .dib - graphics
				

The following file types are not automatically pulled into your source code controller. You can add these files to SourceSafe, but it is not necessary.

   .exe       - application executable
   .dll       - application dynamic link library
   .res       -
				

You should only store copies of these binary files in SourceSafe if you do not have the source code for them. For example, if your project calls a third-party-compiled dll, store the dll in SourceSafe. If your project builds a dll, do not store the dll in SourceSafe, just the files necessary to build it.

Database and Other Data Files

In general, you should not store data files in SourceSafe. If you do, these should be only small data files used for testing your application, not live data files.

The following are additional file types that may be a part of your Visual Basic version 4.0 project. These files can be added to SourceSafe and controlled if you choose:

   .mdb       - Microsoft Access database
   .dbf, .ndx, .mdx - dBASE table and index files
   .dat, .ddf - Btrieve database and index
   .dbf, .dbc, .cdx, .idx - FoxPro free table, database container, and
                            index files
   .dat       - data file created for your application
   .txt       - text file created for your application
   .xls       - Microsoft Excel file created for your application
				

Custom Control and Registry Files

The following additional file types may be a part of your Visual Basic version 4.0 project. These files need to be added to SourceSafe if they have been customized:

   .vbr       - the registry file
   .tlb, .olb - type library
   .vbx       - custom control file for 16-bit applications only
   .ocx       - custom control file for both 16- and 32-bit applications
   .dll       - dependency file (listed in Swdepend.ini).
