Re: firing events from server

Francis,

"Other post by Tinh"? I have not seen this.

Now, if I comprehend what you are doing, it is something like this:

==== myForm.frm ====
Dim WithEvents X as MyCOMWhatever

Sub TreeView1_NodeClick()

  Set X = getobject(blahblah...)
  <do stuff>    'X_SomeEvent is Triggered in your MyCOMWhatever
component
  Set X = Nothing

End Sub

Private Sub X_SomeEvent()       'code never runs
  <blah blah>
End Sub

==== end of myForm.Frm ====

...but it works okay when you do this:

==== myForm.Frm ====
Dim WithEvents X as MyCOMWhatever

Private Sub Form_Load()

  Set X = getobject(blah blah...)

End Sub

Sub TreeView1_NodeClick()

  <do stuff with X>     'X_SomeEvent is Triggered in your MyCOMWhatever
component

End Sub

Private Sub X_SomeEvent()       'code runs
  <blah blah>
End Sub

==== end of myForm.Frm ====

Right?
If so, I think this is as designed behavior due to the way COM has to
pass event handler notificaitons to object instances (in this case, the
form class instance is the event recipient).

Regards
