Do You know how to locate problem when SEHexception object not found
(because of Windows Forms.dll) is raised in window message loop that
I cannot debug in VB ??

I click on combo..
something happens...
.... last END FUNCTION ends..

exception is raised ( no way to debug or trace which object cause it)

program continues on
System.Windows.Forms.Application.Run(frmMainWindow.DefInstance)

Please help

I just discovered that it has something to do with calling

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.
