create an inactive mdi child window

     I have a proble with using the CXTPTabClientWnd, I want to get a multi tab interface but I don't need the initial active mdi child window when your OpenDocumentFile(NULL,FALSE),that's  the messsage event  0n_MDICREATE should't change the active child window and should hild below the origin mdi child window , and the only thing that  user can see the new child window  is the tabitem.      I try to change the source code,but finally, I give up, can anyone help me,thanks a lot.         &n bsp;

add virtual method:

void CChildFrame::ActivateFrame(int nCmdShow)
{
 
 if (GetMDIFrame()->MDIGetActive() != NULL)
  nCmdShow = SW_SHOWNOACTIVATE;
  
 CMDIChildWnd::ActivateFrame(nCmdShow);
}
