I work on a few MFC apps where I want them to display their own FILEVERSION information in the titlebar. I've seen articles on how to get the FILEVERSION information from the resources of other apps & DLLs, but in my case, I want the application to display its own FILEVERSION information. How can this be done within the MFC app?

Assuming you have the full file spec of your image.

CString FileHelper::GetFileVersionString(CString FileName)
{
	DWORD dwHandle, dwLen;
	CString v = "0.0.0";
	if ((dwLen = GetFileVersionInfoSize((LPCTSTR)FileName, &dwHandle)) != 0)
	{
		LPTSTR lpData = (LPTSTR)malloc(dwLen);
		if (GetFileVersionInfo((LPCTSTR)FileName, dwHandle, dwLen, lpData) != 0)
		{
			UINT BufLen;
			VS_FIXEDFILEINFO *pFileInfo;
			if (VerQueryValue(lpData, "\\", (LPVOID *)&pFileInfo, (PUINT)&BufLen) != 0)
			{
				if (LOWORD(pFileInfo->dwFileVersionLS) == 0)
					v.Format("%d.%d.%d", HIWORD(pFileInfo->dwFileVersionMS), LOWORD(pFileInfo->dwFileVersionMS), HIWORD(pFileInfo->dwFileVersionLS));
				else
					v.Format("%d.%d.%d.%d", HIWORD(pFileInfo->dwFileVersionMS), LOWORD(pFileInfo->dwFileVersionMS), HIWORD(pFileInfo->dwFileVersionLS), LOWORD(pFileInfo->dwFileVersionLS));
			}
		}
		free(lpData);
	}
	return v;
}

This CP article CFileVersionInfo - Retrieving a File's full Version Information Resource[^] does what you want.

Thanks. I downloaded the code from that page, but it has compile & link issues.. I got it to compile by adding a type declaration to a loop variable, but now it has a linker error - It gives an "unresolved external symbol" error for CFileVersionInfo::vftable. How were you able to get this to compile & link?

The date on that article is 19 Jun 2002. It's likely that the project was built against an older compiler than you have and there have been some changes that require source and/or symbol changes over the years. The bottom line on articles is "they worked when they were posted but probably not kept up to date"
