When I got the new inspector event, I will create a combo box and toolbar
to the commandbars on the inspector window. And try to add the OnChange
event using the call DispEventAdvise or AtlAdvise.
Both calls return S_OK. however, no one trigger the call when I change the
combo box selection.

Anyone knows how to solve it?

Thanx alot.
