SUMMARY
Although Microsoft Windows and Windows for Workgroups can both display the same version number, you can determine whether Windows for Workgroups is running by using a Windows API call in an Access Basic function.



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.

  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  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!"
