This is another issue that fits in this thread.
I've been messing with the GetFileVersionInfo() but when it's in my cpp, I
get link errors. I can't seem to find a header file that might be missing
so I don't understand it. The code snip is shown below. I have some extra
code because I'm experimenting a bit but the issue is the
GetFileVersionInfo() linker Issue.
*********************************************************
    //get filename, add .exe, then get handle to this filename
    CString strFileName( _T("") );
    strFileName = AfxGetApp()->m_pszExeName;
    strFileName.Append( _T(".exe") );
    HMODULE hmod = GetModuleHandle( strFileName );

    //use GetModuleFileName() to obtain full path of file
    CString strFullPath( _T("") );
    LPTSTR pstr = strFullPath.GetBufferSetLength(MAX_PATH+1);
    DWORD pathLen = ::GetModuleFileName( hmod, pstr, MAX_PATH);

    strFullPath.ReleaseBuffer( pathLen ); //Note: ReleaseBuffer doesn't need
a +1 for the null byte

    //Use GetFileVersionInfo() to get file information
    TCHAR szExePath[MAX_PATH];
    ::GetModuleFileName( NULL, szExePath, MAX_PATH );

    DWORD dwDummy;
    DWORD dwFVISize = GetFileVersionInfoSize( szExePath, &dwDummy );

    LPBYTE lpVersionInfo = new BYTE[dwFVISize];
    GetFileVersionInfo( szExePath , 0 , dwFVISize , lpVersionInfo );

    if( lpVersionInfo )
        delete lpVersionInfo;

    VS_FIXEDFILEINFO *lpFfi;
    DWORD dwFileVersionMS = lpFfi->dwFileVersionMS;
    DWORD dwFileVersionLS = lpFfi->dwFileVersionLS;
    DWORD dwLeftMost = HIWORD(dwFileVersionMS);
    DWORD dwSecondLeft = LOWORD(dwFileVersionMS);
    DWORD dwSecondRight = HIWORD(dwFileVersionLS);
    DWORD dwRightMost = LOWORD(dwFileVersionLS);

    CString sMsg;
    sMsg.Format( _T("Version: %d.%d.%d.%d") , dwLeftMost,
dwSecondLeft,dwSecondRight, dwRightMost );
    MessageBox( sMsg );

These are the liker Errors:

The idea is that the header file is used to create both the string in the
About box and
the values in the .rc file that describes the VERSIONINFO.

I think I'm missing something but I'm interested in this topic.
If you have your version defined in a header file, then you can display it
in the dialog, however, if you did a "property" on the exe file, has it
really changed? If so, then I got lost somewhere in this thread.

Also;
I was under the impression that you can set something in VS that allowed
the
version to change each time you do a build. I don't remember how to do
this
but I always thought this was possible. Now it may only change the Build
number and not anything else, however, this is a good feature. Is this
still possible, if so .... how do you do it?

Thanks

You may want to add a method to your CAboutDlg class like
SetVersionString(LPCTSTR pszVersion) and a data member of type CString
(e.g. CString m_strVersion).
This new method should set the version string, storing it into the
proper
data member.

Then, CAboutDlg::OnInitDialog would get this string and .SetWindowText()
it in the proper static control.

e.g.:

class CAboutDlg
{
   ...
public:
   void SetVersionString(LPCTSTR pszVersion)
   {
       m_strVersion = pszVersion;
   }

...

private:
   CString m_strVersion;
};

In CAboudDlg::OnInitDialog() do:

  m_CtrlStaticVer.SetWindowText(m_strVersion);
