Command Handler problem in Dialog

[ugur_basak]

in my application, i use some dialogs to update some of the data. I want to add some accelerators. I can add this accelerators in other parts of the application, they work but in dialogs i've a problem. for example when i use Ctrl+A i just got a "beep", it doesn't even "OnEditSelectAll" use this function. How can i use accelerators with Dialogs.

You can make a dialog use an accelerator resource (say IDR_DLG_ACCELERARATOR) doing the following: Add the following members to your dialog class:

class CSomeDialog : public CDialog
{
   // All the normal stuff [...]
 
private:
   HACCEL m_hAccelTable;
 
public:
   virtual BOOL PreTranslateMessage(MSG* pMsg);
};

Add the following to the dialog constructor

CSomeDialog::CSomeDialog(/* Constructor parms [...] */)
{
   // What you already have [...]
 
   m_hAccelTable = LoadAccelerators(
                        AfxGetResourceHandle(),
                        MAKEINTRESOURCE(IDR_DLG_ACCELERARATOR));
}

Then add the following function implementation:

BOOL CSomeDialog::PreTranslateMessage(MSG* pMsg)
{
   if (m_hAccelTable && ::TranslateAccelerator(m_hWnd, m_hAccelTable, pMsg))
      return TRUE;
 
   return CDialog::PreTranslateMessage(pMsg);
}
