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..

thank you very much

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 );
      . . .
}
