Here is an example:

Private Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (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
Private Sub Form_Load()
    Dim OSInfo As OSVERSIONINFO, PId As String
'Set the graphical mode to persistent
    Me.AutoRedraw = True
    'Set the structure size
    OSInfo.dwOSVersionInfoSize = Len(OSInfo)
    'Get the Windows version
    Ret& = GetVersionEx(OSInfo)
    'Chack for errors
    If Ret& = 0 Then MsgBox "Error Getting Version Information": Exit Sub
    'Print the information to the form
    Select Case OSInfo.dwPlatformId
        Case 0
            PId = "Windows 32s "
        Case 1
            PId = "Windows 95/98"
        Case 2
            PId = "Windows NT "
    End Select
    Print "OS: " + PId
    Print "Win version:" + str$(OSInfo.dwMajorVersion) + "." + LTrim(str(OSInfo.dwMinorVersion))
    Print "Build: " + str(OSInfo.dwBuildNumber)
End Sub
