Summary
To use accelerators with a modeless dialog box, override thePreTranslateMessage()function in your derived CDialog class.
More information
To use accelerators with your modeless dialog box, perform the followingsteps:

  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.
