C / C++ / MFC

1. I create on the stack the  CCatalogView

2. Inside the CCatalogView class I create a Win32 Window (using Create). Really, does this window is created on the heap or in the stack ? I assume that is created on the stack. Anyway, I tried to explicitly create this window on the heap, using new (on the CreatePane) & delete (on the destructor) functions  but it also fails.

3. Now, according to my assumptions that both objects are in the stack, at the exiting procedure, it disposes first the last inserted item which is the Win32 Window (as I mentioned, I assume it created on the stack) and then the CCatalogView class itleft.

VERIFY(Create(_T("MyWind"), NULL, WS_CHILD | WS_VISIBLE, CXTPEmptyRect(), pParentWnd,  IDD_TABSHEET2, &context));

// self destruction
void CView::PostNcDestroy()
{
	// default for views is to allocate them on the heap
	//  the default post-cleanup is to 'delete this'.
	//  never explicitly call 'delete' on a view
	delete this;
}

void CCatalogView::PostNcDestroy()
{
	// TODO: Add your specialized code here and/or call the base class
	_ASSERTE( _CrtCheckMemory( ) );

	//Don't call default PostNCDestroy which it calls CView:: delete this
	//because you get a heap corruption since the view is created on the stack.
	//CFormView::PostNcDestroy();
