Neither ... it's a VB problem. VB requires you to define the control with "WithEvents", like this:

Dim WithEvents TabControl As New TabControl()

Probably if you drop a control on your Form in the IDE, it probably generates the code this way (I don't know, I don't have or use VB), so I'm guessing you probably added this dynamically. Anyway, define it as above with "WithEvents" and it should do the trick.

I just Googled the error message to come up with this answer.
