Hi,
I have docking bars that i want to destroy when they are closed.
I override the NcButtons_HandleClick function, and if it’s time to kill my dialog, i call Destroy on the bar, and not call the default CExtControlBar::NcButtons_HandleClick.
This all works fine until i get to the tabbed scenario (AGAIN...)
What happens is that the NcButtons_HandleClickis called of each docked dialog, i destroy them all, but then it crashes in CExtDockDynTabBar,
in the funtion _RepositionTabbedChilds line 185:
ASSERT( hDWP != NULL );
This is the stack:

Please make a search for the KillBar word in this forum. The results will show how to use a KillBar() function in your code.

I’m sorry, but this solution is not working.
I still get a crash in my application.

Because you are using a modified version of the control bar, we would you to modify one of our samples so it would reproduce the crash and send it to us.

What we actually mean is we do not really know which methods you have overridden in your CExtControlBar-derived class except for those we discussed. So we cannot guess what causes the problem.

Dear Support,
I did not change anything but overriding the CBaseDockBar::NcButtons_HandleClick.
This is what i did there:
if( pNcAreaButton->IsKindOf(RUNTIME_CLASS(CExtBarNcAreaButtonClose)))
{
// We want to destroy the dialog, and not hide it:
KillBar(this);
return true;
}
That’s all.
Please note that there is a new thread i started today regarding this bug plus a fix for it.
