ACC: How to Tell If Windows for Workgroups Is Running

MORE INFORMATION

The following example can be used to determine if Windows for Workgroups is running.

NOTE: In the following sample code, an underscore (_) is used as a line-continuation character. Remove the underscore from the end of the line when re-creating this code in Access Basic.

1. Create a new module and enter the following code:
   

         '***************************************************************
         '  Declarations section of the module
         '***************************************************************
            Option Explicit
            Const WNNC_NET_MultiNet = &H8000
            Const WNNC_SUBNET_WinWorkgroups = 4
            Const WNNC_NET_TYPE = 2
   
            Declare Function WNetGetCaps% Lib "User" (ByVal nIndex%)
   
         '================================================================
         'This function returns True if Windows for Workgroups is running,
         'or False if it is not (generic Windows). It accomplishes this by:
         ' - Calling WNetGetCaps and retrieving the net type flag.
         ' - Inspecting the low word of the flag to see if the Windows for
         '   Workgroups bit is set.
         '================================================================
            Function IsWFW% ()
               Dim wNetType As Integer
   
               wNetType = WNetGetCaps(WNNC_NET_TYPE)
               IsWFW = False
               If (wNetType And WNNC_NET_MultiNet) Then
                  IsWFW = ((wNetType And &HFFFF) And _
                        WNNC_SUBNET_WinWorkgroups) <> 0
               End If
            End Function
   						

2. From the View menu, choose Immediate Window. Type the following in the Immediate window:
   
   MsgBox IIf(IsWFW(), "WFW", "Windows") & " is running!"

If Windows for Workgroups is running, you will see the message "WFW is running!"
