Hi,

 I add a child to the CXTPTabClientWnd that is not a MDI window,

but in order to do that I had to change the following lines so that the control would not crash...

CXTPTabClientWnd::UpdateContents()

<..>

Now...

    pNewItem = pFoundItem = AddItem(pChildWnd);

     if ( pNewItem )
    {
    
     pFoundItem->m_hWnd = pChildWnd->GetSafeHwnd();

     pFrameWnd->SendMessage(WM_X TP_NEWTABITEM, (WPARAM)pNewItem);
     pNewItem->GetTabManager()-& gt;SetSelectedItem(pNewItem);
    }

<..>

Before ...

    pNewItem = pFoundItem = AddItem(pChildWnd);

     pFoundItem->m_hWnd = pChildWnd->GetSafeHwnd();

     pFrameWnd->SendMessage(WM_X TP_NEWTABITEM, (WPARAM)pNewItem);
     pNewItem->GetTabManager()-& gt;SetSelectedItem(pNewItem);

<..>

If is there another way to do it please tell me how...

By the way, the effect I had is very nice, I put a CHtmlView to fill the background of the Tab Client Window, so my OnFillBackground is very powerfull now... ;-)

Regards

André
