How To Adding Splitter Bars Support to Active Document Server

MORE INFORMATION

Steps to be taken:

1. Copy BINSCRB sample from Visual C++ CD-ROM.
2. Override CreateInPlaceFrame() in CScribDoc class (a COleServerDoc- derived class). This function is called to create a frame window for in- place editing. The function is modified so it uses a splitter window (CSplitterWnd class) as the view of the in-place frame window (a COleDocIPFrameWnd-derived class).

         COleIPFrameWnd* CScribDoc::CreateInPlaceFrame(CWnd* pParentWnd)
         {
            ASSERT_VALID(this);
            ASSERT_VALID(pParentWnd);
      
            // Get run-time class from the doc template.
            CDocTemplate* pTemplate = GetDocTemplate();
            ASSERT_VALID(pTemplate);
      
            // Use existing view if possible.
            CView* pView = NULL;
            CFrameWnd* pFrame = GetFirstFrame();
            if (pFrame != NULL)
            {
               pView =
                  (CView*)pFrame->GetDescendantWindow(AFX_IDW_PANE_FIRST,
      TRUE);
               if (pView != NULL)
               {
                  ASSERT_KINDOF(CView, pView);
                  m_dwOrigStyle = pView->GetStyle();
                  m_dwOrigStyleEx = pView->GetExStyle();
               }
            }
      
            // Create the frame from the template, ALWAYS use the CView of the
            // CSplitterWnd.
            COleIPFrameWnd* pFrameWnd = (COleIPFrameWnd*)
               pTemplate->CreateOleFrame(pParentWnd, this, FALSE);
            if (pFrameWnd == NULL)
               return NULL;
      
            // Connect the splitter window (CSplitterWnd class) to the
            // COleDocIPFrameWnd.
            CWnd* split = pFrame->GetWindow(GW_CHILD);
            VERIFY(pFrame == split->SetParent(pFrameWnd));
      
            // Remember the original parent window for deactivate--uses the
            // CFrameWnd-derived class (that is, CMDIChildWnd for MDI).
            m_pOrigParent = pFrame;
      
            // Set the active view of COleDocIPFrameWnd.
            pFrameWnd->SetActiveView(pView, FALSE);
            pFrameWnd->RecalcLayout();
            pView->ModifyStyleEx(WS_EX_CLIENTEDGE, 0, SWP_DRAWFRAME);
      
            // Verify the type.
            ASSERT_VALID(pFrameWnd);
            ASSERT_KINDOF(COleIPFrameWnd, pFrameWnd);
            return pFrameWnd;
         }
   					

3. Override DestroyInPlaceFrame() in CScribDoc class (a COleServerDoc- derived class) to destroy the in-place frame window and return the server application's document window to its state before in-place activation.

         void CScribDoc::DestroyInPlaceFrame(COleIPFrameWnd* pFrameWnd)
         {
            ASSERT_VALID(this);
            ASSERT_VALID(pFrameWnd);
      
            // connect view to original, if existing view was used
            if (m_pOrigParent != NULL)
            {
               CView* pView = (CView*)pFrameWnd->GetDescendantWindow(
      AFX_IDW_PANE_FIRST, TRUE);
               ASSERT_VALID(pView);
      
               // Leaving the focus on an MDI child or one of its child
               // windows causes Windows to get confused when the child window
               // is destroyed, not to mention the fact that the focus will be
               // out of sync with activation.
               if (::GetFocus() == pView->m_hWnd)
               {
                  // Move focus to somewhere safe.
                  HWND hWnd = ::GetParent(pFrameWnd->m_hWnd);
                  if (hWnd != NULL)
                     ::SetFocus(hWnd);
      
                  // Check again.
                  if (::GetFocus() == pView->m_hWnd)
                     SetFocus(NULL); // last ditch effort
               }
      
               // Set parent of the splitter window (CSplitterWnd class) to be
               // the CFrameWnd-derived class (that is, CMDIChildWnd for MDI
               // application).
               ASSERT_KINDOF(CFrameWnd, m_pOrigParent);
               CFrameWnd* frame = (CFrameWnd*) m_pOrigParent;
               CWnd* split = pFrameWnd->GetWindow(GW_CHILD);
               VERIFY(pFrameWnd == split->SetParent(frame));
      
               // Set the active view of CFrameWnd-derived class (that is,
               // CMDIChildWnd for MDI application).
               frame->SetActiveView(pView, FALSE);
               frame->RecalcLayout();
      
               m_pOrigParent = NULL;
      
               // Remove any scrollbars added because of in-place activation.
               if ((m_dwOrigStyle & (WS_HSCROLL|WS_VSCROLL)) == 0 &&
                  (pView->GetStyle() & (WS_HSCROLL|WS_VSCROLL)) != 0)
               {
                  ::SetScrollRange(pView->m_hWnd, SB_HORZ, 0, 0, TRUE);
                  ::SetScrollRange(pView->m_hWnd, SB_VERT, 0, 0, TRUE);
               }
      
               // Restore old 3D style.
               pView->ModifyStyleEx(0, m_dwOrigStyleEx & WS_EX_CLIENTEDGE,
                  SWP_DRAWFRAME);
      
               // Force recalc layout on splitter window.
               CSplitterWnd* pSplitter = CView::GetParentSplitter(pView,
                  TRUE);
               if (pSplitter != NULL)
                  pSplitter->RecalcLayout();
            }
      
            // No active view or document during destroy.
            pFrameWnd->SetActiveView(NULL);
      
            // Destroy in-place frame window.
            pFrameWnd->DestroyWindow();
         }
