I'm creating an app using WCE and I'm trying to get the
display to toggle wrapping and scrolling of text.  

The scrollbar appears and disapears, but the text won't
redraw, it stays in its previous state.  

I'm reading the text currently displayed into a buffer,
change scrolling state, and then redraw text.

Any ideas??  Thanks!!

Here's my code:

void CTextViewerView::OnViewWrappedtowindow()
{
        CString RedrawTextBuffer;
     CEdit& theEdit = GetEditCtrl();
     
     //Read Text from window
     GetWindowText(RedrawTextBuffer);      
     LPTSTR p = RedrawTextBuffer.GetBuffer(65536);
     
     CWnd* pMain = AfxGetMainWnd();
     CMenu* menu_bar = pMain->GetMenu();
     CMenu* view_menu = menu_bar->GetSubMenu(2);

        //Change display of Window (Wrapping or Scrolling)
     if (WrapText)
     {                       //Add scrollbar
          ModifyStyle(0, ES_AUTOHSCROLL|WS_HSCROLL);
          view_menu->CheckMenuItem
(ID_VIEW_WRAPPEDTOWINDOW, MF_BYCOMMAND | MF_UNCHECKED);
          WrapText = 0;
     }
     else
     {                          //Do Word Wrap
          ModifyStyle(ES_AUTOHSCROLL|WS_HSCROLL, 0);
     
          view_menu->CheckMenuItem
(ID_VIEW_WRAPPEDTOWINDOW, MF_BYCOMMAND | MF_CHECKED);
          WrapText = 1;
     }

        //Reset text to new window
     theEdit.SetWindowText((LPCTSTR)p);

//Tried to add the following but doesn't help
/*     ShowWindow(SW_SHOW);
     pMain->UpdateWindow();

     OnUpdate(NULL, 0, NULL);
*/
}
