hmmm.. when I enable unmanaged debugging I discovered that
the stack is extremely big, the topmost is my error (that error is not the
first one, there was another one caused by
__FrameUnwindToState(EHRegistrationNode *, void *, const _s_FuncInfo *, int)
)
but between nothing useful.
Hmm.. it must be something with stack. I am adding many nodes to combo
box and tree view, maybe some actions are triggered, but te stack gets
an overflow. But why the problem occured only now ? I did not
remove/added/replaced anything special in project.

SOLVED IT!!

with help of another web site.
It was because some sort of bug when enabling XPVisualStyles.
is hould be solved by adding DoEvents, but did not help me.
Another option is said to be some lately XP patch, I must check it.

I just discovered that it has something to do with calling
DoEvents, but I need progress indication.

I had the same problem in Windows application. Deleting Application.EnableVisualStyles() helped.

I just ran into this problem right now for the first time and this thread saved me HOURS of debugging thanks. FYI, I was calling Application.EnableVisualStyles() in the Load handler for my form instead of the main form's Main(). I did read an article a long time ago about NOT calling EnableVisualStyles from the load, but can't remember where. I do not run into the SEH problem even when using visual styles after moving it to Main();

Thanks
