ACC2000: Sample Function to Determine Windows 95/98 or NT Version

• Microsoft Access 2000

SUMMARY

Advanced: Requires expert coding, interoperability, and multiuser skills.

This article describes how you can use the GetVersionEx() Windows API function to determine the version number of the operating system (Microsoft Windows NT or Windows 95/98) running on the computer.

MORE INFORMATION

Although the GetVersion() function is still supported under Win32, it has been superseded by GetVersionEx(), which identifies Windows 95/98, returns more accurate information about the build of Windows, and no longer returns the version of MS-DOS.

1. Create a module and type the following code in the Declarations section:
   

   
   '====================================
   ' Global Declarations
   '====================================
   
   Option Explicit
   
   Type OSVERSIONINFO
      dwOSVersionInfoSize As Long
      dwMajorVersion As Long
      dwMinorVersion As Long
      dwBuildNumber As Long
      dwPlatformId As Long
      szCSDVersion As String * 128   ' Maintenance string for PSS usage.
   End Type
   
   Public Const VER_PLATFORM_WIN32s = 0
   Public Const VER_PLATFORM_WIN32_WINDOWS = 1
   Public Const VER_PLATFORM_WIN32_NT = 2
   
   Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" _
     (lpVersionInformation As OSVERSIONINFO) As Long 





2. Type the following procedure:

   
   Function SysVersions32()
   
      Dim v As OSVERSIONINFO, retval As Long
      Dim WindowsVersion As String, BuildVersion As String
      Dim PlatformName As String
   
      v.dwOSVersionInfoSize = Len(v)
      retval = GetVersionEx(v)
   
      WindowsVersion = v.dwMajorVersion & "." & v.dwMinorVersion
      BuildVersion = v.dwBuildNumber And &HFFFF&
   
      Select Case v.dwPlatformId
         Case VER_PLATFORM_WIN32_WINDOWS
            PlatformName = "Windows 95/98"
         Case VER_PLATFORM_WIN32_NT
            PlatformName = "Windows NT"
      End Select
   
      MsgBox "Platform: " & PlatformName & vbCrLf & _
         "Version: " & WindowsVersion & vbCrLf & _
         "Build: " & BuildVersion
   
   End Function 




3. To test this function, type the following line in the Immediate window, and then press ENTER:

   
   ?SysVersions32() 

   Note that the message box displays the operating system's name, version, and build number.
