INFO: Using Accelerators with an MFC Modeless Dialog Box (117500)

MORE INFORMATION

1. Create a modeless dialog box. For additional information, please see the following article in the Microsoft Knowledge Base:

   103788 Creating a Modeless Dialog Box with MFC Libraries

2. Insert this sample code into the files listed above the code:

      // .h file with your derived CDialog class.
      class CModeless : public CDialog
      {
         .
       public:
         virtual BOOL PreTranslateMessage(MSG*);
         .
      };
   
      //.cpp file.
      BOOL CModeless::PreTranslateMessage(MSG* pMsg)
      {
         HACCEL hAccel =
         ((CMainFrame*)AfxGetApp()->m_pMainWnd)->GetAccelTable();
         if(!(hAccel &&
              ::TranslateAccelerator(AfxGetApp()->m_pMainWnd->m_hWnd, hAccel,
                                     pMsg)))
              return CDialog::PreTranslateMessage(pMsg);
         else
            return TRUE;
      }
   
      // Mainfrm.h file, where CMainFrame is the main window class.
      HACCEL CMainFrame::GetAccelTable() { return m_hAccelTable; }
   						

3. Create the accelerators with App Studio, or with Resource View from the Project Workspace in Visual C++ 32-bit Edition, version 4.0. The accelerators should be in the IDR_MAINFRAME accelerator table. They should also have the same ID as the controls or menu items with which they are associated.
