C++ Error (With Apps made in VB 6.0 Enterprise Edition)

Hey ya,,

I've just, twice in a row got an error from a app i made in VB:

"C++ Error:
- Pure virtual function call"

: My Code is attached, : Heck, god knows what is is, but this is after i click on the tab strip, it works for ages, then suddenly, BOOM, it goes..

If anyone knows the problem?
