[DUG] tricky event question

[Conor Boyd]

The way you've described it "smells" a bit to me.  Why do you need to
free the combobox?  Why not just hide it or something similar?

However, if you truly want to do it, look into posting a message to the
form using PostMessage, and then handle the message on the form, and
free the combobox at that point.

Hi Guys

I have a combobox with an event (onChange) that refreshes the display.  
As part of that refresh the combobox is freed.  This causes an AV as the
combo box has not yet finished processing its event but is being freed.

What would be the best way of dealing with this scenario? 

Cheers
Rob
