OS determine

I am looking through the search to find out how to detemine the OS.

Basically all I need to do is determine if its win 2000 do something. If win xp do something. I am only going to be installing this program on 2000 or xp only.

VB Code:

Option Explicit
 
Private 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
 
Private Declare Function GetVersionEx Lib "kernel32" _
    Alias "GetVersionExA" (lpVersionInformation As OSVERSIONINFO) As Long
 
Private Const VER_PLATFORM_WIN32_NT = 2

Function GetVersion() As String
    Dim os As OSVERSIONINFO
    os.dwOSVersionInfoSize = Len(os)
    GetVersion = "N/A"
    If GetVersionEx(os) Then

    Else

    End If
End Function
 
Private Sub Form_Load()
    Debug.Print GetVersion
End Sub

VB Code:

Private Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (ByRef lpVersionInformation As OSVERSIONINFO) As Long
Private Type OSVERSIONINFO
    dwOSVersionInfoSize As Long
    dwMajorVersion As Long
    dwMinorVersion As Long
    dwBuildNumber As Long
    dwPlatformId As Long
    szCSDVersion As String * 128
End Type
