SUMMARY
This article contains code and instructions that demonstrate how to create a sample application that uses some of the functions in VERSION.DLL to retrieve file information embedded into a file with the resource compiler (RC.EXE).

NOTE: This code only works in Visual Basic version 4.0, 32-bit for Windows. To obtain a Visual Basic version 4.0 16-bit for Windows, example of this code, please see the following article in the Microsoft Knowledge Base:

112731 : How to Use Functions in VER.DLL -- a 16-bit Sample Application

This Visual Basic application was modeled after the Verstamp sample program included in the Microsoft Windows Software Development Kit (SDK).

Additional information can be found in the following documents:


 * Microsoft Win32 SDK
 * Win32 API Declarations for Visual Basic (WIN32API.TXT) located in the WINAPI subdirectory of Visual Basic 4.0



MORE INFORMATION
Instead of offering this article in a number of steps, we have modified our usual format to make it easier for you to create and use this Visual Basic application. Therefore, the three files you need (VERINFO.BAS, VERINFO1.FRM, VERINFO2.FRM) are listed below so you can easily copy them into a text editor and save them as separate files. Instructions on how to use the files are embedded in the files as comments.

How to Create and Run the Program

 * 1) Start Visual Basic. Form1 is created by default.
 * 2) From the File menu, choose Remove File to remove Form1.
 * 3) From the File menu, choose Add File to add VERINFO.BAS.
 * 4) Repeat step 3 to add VERINFO1.FRM and VERINFO2.FRM to the project.
 * 5) From the Options menu, choose Project and set Start Up Form to Form1.
 * 6) Run the application.
