Topic: CXTTabView Destructor Heap Corruption

I have an application with CXTTabView that pops up a window with a "Heap corruption" warning while working through the windows functions after calling the CXTTabView destructor, when exiting from the application.

This error occurs in wincore.cpp at line 1033 (Visual Studio 2010 on W7), which is the line

bResult = ::DestroyWindow(m_hWnd)

below. At this time, the debugger gives ??? for m_hWnd and for m_pCtrlSite.

Here is a cut and paste from wincore.cpp showing where the error occurs.

#ifdef _AFX_NO_OCC_SUPPORT

if (m_hWnd != NULL)

bResult = ::DestroyWindow(m_hWnd);

#else //_AFX_NO_OCC_SUPPORT

if ((m_hWnd != NULL) || (m_pCtrlSite != NULL))

{

if (m_pCtrlSite == NULL)

bResult = ::DestroyWindow(m_hWnd);

else

bResult = m_pCtrlSite->DestroyControl();

}

#endif //_AFX_NO_OCC_SUPPORT

Does anyone have an idea of what might be causing this?

Ideas about how to do additional debugging are also welcome.

Thanks,
Tom

I did more testing and the heap corruption occurs when I attach a CTreeView-derived class to a CXTPDockingPane pane, so I will start a new topic in the DockingPane forum asking what about attaching a view might cause heap corruption.

Thanks in advance for any suggestions,

Tom
