You can detect and display the current operating system platform, version, and build number by using a CommandButton control and the OSPlatform, OSVersion, and OSBuild properties. You can test this by adding a CommandButton control to a form and then adding the following code the cmdDetectOS_Click event procedure:
Private Sub cmdDetectOS_Click()
Dim MsgEnd As String
Select Case sysDetectOS.OSPlatform
Case 0
MsgEnd = "Unidentified"
Case 1
MsgEnd = "Windows 95, ver. "& _
CStr(sysDetectOS.OSVersion) & "(" & _
CStr(sysDetectOS.OSBuild) & ")"
Case 2
MsgEnd = "Windows NT, ver. " & _
CStr(sysDetectOS.OSVersion) & "(" & _
CStr(sysDetectOS.OSBuild) & ")"
End Select
MsgBox "System: " & MsgEnd
End Sub
For More Information See OSPlatform, OSVersion, and OSBuild properties.
