after hours of searching i still haven’t found a reason why a simple program doesn’t work. The following screen shot can help to clarify my problem:
The class MyReceiver uses the interface listSelectionNotificationReceiver and adds the methods SelectionChanged and SelectionChanging. In SelectionChanging I added a MessageBox(“Changing”) and in SelectionChanged a MessageBox(“Changed”). No compilation errors but nothing happens (no messages) when I select another row in Listbox1.
