Yes, you need to import the form and module in your app then call it similar to the msgbox, here is one example I use for a shut-down message (it counts down from 5 seconds-last argument):
Code:
Public Function vcCheckForShutDown()
If DLookup("[Shutdown]", "[usysShutDown]") = True And DLookup("[Initiator]", "[usysShutDown]") <> fOSUserName() Then
'initiate shut-down
'display message
MBox "Admin message from " & DLookup("[InitiatedBy]", "[qryShutDownMessage]") & ": " & vbCrLf & DLookup("[MessageDisplayed]", "[qryShutDownMessage]") & ". ", vbCritical + vbExclamation, "Admin Message", , , , , 5
On Error Resume Next
DoCmd.Quit acQuitSaveAll
End If
End Function
Cheers,
