Events in ActiveX controls

[brenaaro]

Will an ActiveX control wait for any code in an event handler to finish executing before processing the code after the RaiseEvent call?

Example:

'In the ActiveX control...
   MsgBox "1"
   RaiseEvent Call("2")
   MsgBox "3"
   '...rest of code
 
'In the calling application
Public Sub MyControl_Call(Msg As String)
   MsgBox Msg
End Sub

Will I get 1,2,3?

Run it and see. I don't think it will stop and wait.

Awwww!!! Do I have to do EVERYTHING myself?!?!

I decided to just move the code after that RaiseEvent to a public method, and let the user decide if that code should be executed or not by calling the method..makes it easier on me

I believe it does wait. In other ActiveX objects it does (dll/exe). Because you can get a return value from the event and can decide what to do from there. That is kind of how the Cancel parameter works for things like the Unload Event of a form.

'in axtivex
Public Event Closing(Cancel As Boolean)
 
dim bCancel as boolean
RaiseEvent Closing(bCancel)
If bCancel=True then Exit Sub
'user didn't cancel in the event so continue
 
'in the event
Public Sub Obj_Closing(Cancel As Boolean)
  'this gets returned to the object
  Cancel=True
End Sub

it should wait on a message box at least since it will display modally to the control...

[brenaaro]

Ah yes the Unload and QueryUnload events..that makes sense now that I think of it.

I was pretty sure if I had a message box displaying it would wait, but it was highly unlikely we would have a message box in the event handler in question.

Anyways, thanks for the feedback as always.
