Hi Everyone,

I am creating a hidden CHtmlView, just so I can print it's content. It
works perfectly, but I am bit uncomfortable with it. I have a feeling that
it's going to bite me later.

void LSActivityDoc::OnFilePrint()
{
   //LSActivityPrintView inherits from CHtmlView
   CRuntimeClass *pViewClass = RUNTIME_CLASS(LSActivityPrintView);
   LSActivityPrintView * pView = (LSActivityPrintView
*)pViewClass->CreateObject();

   CRect rect(0,0,0,0);
   if (!pView->Create(NULL, NULL, WS_CHILD | WS_BORDER,
      rect, ::AfxGetMainWnd(), (AFX_IDW_PANE_FIRST), NULL))
  {
      TRACE0( "Unable to create printing view\n" );
      return;
  }

  pView->SendMessage(WM_INITIALUPDATE);
  pView->Navigate2("www.yahoo.com");

  while (pView->GetBusy())
  {
        //Yeild is simply a message pump.
      ((CLSEditorApp *)AfxGetApp())->Yeild();
  }

  pView->OnFilePrint();

  //this is what I am uncomfortable about.
  pView->DestroyWindow();
}

Since OnFilePrint returns immidately (brings up CPrintDialog, and then
prints) I am not sure if it is safe to call DestroyWindow as I am doing.

Any thoughts?
