A lot of Controls, including System.Windows.Forms.ListBox will fire unexpected events, forcing you to code defensively. As an example, a SelectionChanged event (or whatever it is called) may be fired when an item gets deselected, which you can check by looking for a negative SelectedIndex, or a SelectedItem being null. If you don't, you're bound to run into trouble.

Also don't be surprised it you use OwnerDraw mode and get MeasureItem/DrawItem events with an index of -1.

IMO all these can be avoided by proper testing before acting; and all can be caught with proper try-catch constructs.

Finally, without actual code, we can't provide more specific help. I have noticed you seldom provide code when in fact you should.
