SYMPTOMS
GetVersion returns 3.10 when running under Windows for Workgroups version 3.11.

CAUSE
GetVersion still returns 3.10 from Windows for Workgroups version 3.11 because there are too many applications that are checking for version 3.10. GetVersion returns 3.10 to maintain compatibility with those applications that check for Windows version 3.10.

RESOLUTION
Windows applications that use the C language can use the following set of functions to get the actual version information.

GetFileVersionInfoSize("user.exe"...); GetFileVersionInfo("user.exe"...); VerQueryValue(...); For a complete sample application that does this, please see the sample in the ..\SAMPLES\VERSTAMP directory from Microsoft Visual C++.

Below is a Visual Basic program that uses the GetFileVersionInfo functionto get the actual version information.

  Declare Function GetFileVersionInfo% Lib "ver.dll" (ByVal lpszFileName$, ByVal handle As Any, ByVal      cbBuf&, ByVal lpvData$)

Dim pos As Integer Dim version As String * 255 Dim ans As String ' get the version info and fill the version string ret% = GetFileVersionInfo("user.exe", 0&, 254, version) ' find the position in the string where the FileVersion stamp is. pos = InStr(1, version, "FileVersion") ' 12 = lengh of "FileVersion" +1 for the null ' 4 = length of string to return i.e. "3.11" ans = Mid$(version, pos + 12, 4) ' display answer MsgBox ans

STATUS
This behavior is by design.
