  What I mean is that in a windowed process, like
an HTA, there can be numerous events responded
to without holding up the process.
   With VBS, there's no way to wait for events
while doing other things. An event is really just an
asynchronous function, where one has to wait for
the return while looping. This is a simplified version
of how I had to code an emailing component to
allow for asynchronous operation. It works, but
it gets complicated trying to keep the script running,
and not locked, while asynchronous ops are carried
out:

'---------------------------------
Var1 = False
DoIt

Do Until Var1 = True
Loop
  WScript.DisconnectObject Ob

Sub DoIt()
  Set Ob = WScript.CreateObject("Some.Obj", "Ob_")
  '-- do stuff.
   Ob.DoSomethingInvolved
   While Ob.Busy = True
    Wend
End Sub

Sub Ob_Onfinish()
  '--do stuff
  Var1 = True
End Sub

Sub Ob_Report(data)
  RecordReport data
End Sub
