Stumped on getting prodect version #

[yetti]

Please help, I am pretty new at all this.

I am righting a program that automatically updates files on a vendors program to get the product to the lastest version. I want to check the version of the program on the pc before I upgrade the files. the only place I can find the version info of the product is when i right click the exe file and choose properties, then go to the version tab. Can I automactically pull this info into my VB program at runtime?

I was told the info may be in the header of the exe, is this true? If so can anyone tell me how to scan the header of a file and pull it into a vb program. I can not find to much info on the web about these questions.

thanks alot

GetFileVersionInfo
The GetFileVersionInfo function returns version information about a specified file.

As with other file installation functions, GetFileVersionInfo works only with Win32 file images. It does not work with 16-bit Windows file images.

BOOL GetFileVersionInfo(
  LPTSTR lptstrFilename,  // pointer to filename string
  DWORD dwHandle,         // ignored
  DWORD dwLen,            // size of buffer
  LPVOID lpData           // pointer to buffer to receive 
                          // file-version info.
);

Parameters
lptstrFilename
Pointer to a null-terminated filename string that specifies the file of interest.
Windows 95/98: The short path form of the specified file name must be less than 126 characters.

dwHandle
This parameter is ignored.
dwLen
Specifies the size, in bytes, of the buffer pointed to by the lpData member.
Call the GetFileVersionInfoSize function first to determine the size, in bytes, of a file's version information. The dwLen member should be equal to or greater than that value.

If the buffer pointed to by lpData is not large enough, the function truncates the file's version information to the size of the buffer.

lpData
Pointer to a buffer to receive file-version information.
You can use this value in a subsequent call to the VerQueryValue function to retrieve data from the buffer.

The file version information is always in Unicode format.

Return Values
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks
Call the GetFileVersionInfoSize function before calling the GetFileVersionInfo function. The file-version information has the format indicated by the VS_VERSIONINFO structure.

QuickInfo
Windows NT: Requires version 3.1 or later.
Windows 95/98: Requires Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in winver.h.
Import Library: Use version.lib.
Unicode: Implemented as Unicode and ANSI versions on Windows NT.
