When I need to derive a class from two classes whose base class is CWnd. Why this scenario is going to fail?

But how do i get a pointer to each view. I want to pass data to the view

// this is the MFC example from the docs
 
CMDIFrameWnd *pFrame = 
             (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
 
// Get the active MDI child window.
CMDIChildWnd *pChild = 
             (CMDIChildWnd *) pFrame->GetActiveFrame();
 
// or CMDIChildWnd *pChild = pFrame->MDIGetActive();
 
// Get the active view attached to the active MDI child
// window.
CMyView *pView = (CMyView *) pChild->GetActiveView();

// Iterate through doc templates
 
POSITION DocTemplatePos = AfxGetApp()->GetFirstDocTemplatePosition();
while (DocTemplatePos != NULL)
{
   CDocTemplate *pTmpl = AfxGetApp()->GetNextDocTemplate(DocTemplatePos);
 
   // Iterate through documents for the current template
 
   POSITION DocPos = pTmpl->GetFirstDocPosition();
   while (DocPos != NULL)
   {
      CDocument *pDoc = pTmpl->GetNextDoc(DocPos);
 
      // Iterate through views for the current document
 
      // You could use CDocument::UpdateAllViews() or ...
 
      POSITION ViewPos = pDoc->GetFirstViewPosition();
      while (ViewPos != NULL)
      {
         CView *pView = pDoc->GetNextView(ViewPos);
 
         // Do something with the current view
      }
   }
}
