Having a a modal dialog with a menubar, I just upgraded the library to 9.70.

Now an assertion appears sometimes(!) inside the following function

void CXTPPopupBar::Animate()
{
 CXTPCommandBar* pParentCommandBar = GetParentCommandBar();

 BOOL bAnimate = pParentCommandBar? pParentCommandBar->m_bAnimatePopup: TRUE;

 if (bAnimate)
 {
  if (IsCustomizeMode() || GetWindow(GW_CHILD))
   bAnimate = FALSE;
 }
 
 ...

The bold function GetWindow(GW_CHILD) asserts with a NULL m_hWnd handle. Although it asserts, it still behaves correctly.

Question: Anything I can do to get rid of that assertion?

Thanks
Uwe

Addendum: Seems it was due to the fact I put a breakpoint somewhere in some related code and the created windows seems to confuse things a little bit, once the debugger breaked and then continued.

It did not appear anymore. Sorry for posting.

Now it appears again, even without any debug breakpoints occuring before.

This is the call stack when the assertion fails:

Maybe someone at Codejock can check whether this is an issue with the new library.

Thanks

Additional information:

The error occurs when clicking a main menu item (the popup submenu appears) and then moving the the mouse coursor over the other main menu items.

After the assertion, a shadow remains on top of all other windows:

As far as I can tell, this did not happen before version 9.70. And it only appears in menus inside dialog boxes.

Hi

Strange, m_hWnd can't be NULL in Animate member. :(

Can you reproduce it with DialogSample?

Thanks for your feedback.

I just tried and unfortunately could not reproduce it with the DialogSample. Although I based my code on that sample, I will try and see what I do different than the sample.

Thanks
Uwe
