Dear support

I have a CExtResizableDialog that has a CExtTabPageContainerWnd formed by several CExtResizableDialog

My problem is how can I access this from a CExtResizableDialog in
CExtTabPageContainerWnd a main CExtResizableDialog?

CExtResizableDialog m_DialogMain;

CExtTabPageContainerWnd m_MyTab;

CExtResizableDialog m_DialogTab1;
CExtResizableDialog m_DialogTab2;
CExtResizableDialog m_DialogTab3;
CExtResizableDialog m_DialogTab4;

Create All;

from m_DialogMain I can access without problems to
m_MyTab and turn m_DialogTab1, m_DialogTab2, m_DialogTab3, m_DialogTab4
but from m_DialogTab1, m_DialogTab2, m_DialogTab3, m_DialogTab4
How you can access to m_DialogMain?

using GetParent() gives me exception error to execute.

Thank you for your kindness

best regards..

You should invoke the GetParent() API two times from any methods of the m_DialogTab*** dialog pages because the first parent is the CExtTabPageContainerWnd window and the second parent is the m_DialogMain window.

void CYourDialogPageClass::SomeMethod()
      // 1st
CWnd * pWnd = GetParent();
      ASSERT_VALID( pWnd );
      ASSERT( pWnd->GetSafeHwnd() != NULL );
      ASSERT( pWnd->IsKindOf( RUNTIME_CLASS( CExtTabPageContainerWnd ) ) );

      // 2nd
      pWnd = pWnd->GetParent();
      ASSERT_VALID( pWnd );
      ASSERT( pWnd->GetSafeHwnd() != NULL );
CYourMainDialogClass * pMainDialog = STATIC_DOWNCAST( CYourMainDialogClass, pWnd );
      . . .
