The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

  afx_msg UINT OnGetDlgCode();
 
  Remarks
 
  Normally, Windows handles all DIRECTION-key and TAB-key input to a CWnd
  control. When OnGetDlgCode is called, a CWnd control can choose a
  particular type of input to process itself.
 
  Although the ◄Default► and ◄DefWindowProc► member functions always
  return 0 in response to the ◄WM_GETDLGCODE► message, the OnGetDlgCode
  functions for the predefined control classes return a code appropriate
  for each class.
 
  OnGetDlgCode's returned values are useful only with user-defined dialog
  controls or standard controls modified by subclassing.
 
  This message-handler member function calls the ◄Default► member
  function. Override this member function in your derived class to handle
  the ◄WM_GETDLGCODE► message.
 
  Return Value
 
  One or more of the following values, indicating which type of input the
  application processes:
 
  Value                Meaning
 
  DLGC_DEFPUSHBUTTON   Default pushbutton.
 
  DLGC_HASSETSEL       EM_SETSEL messages.
 
  DLGC_PUSHBUTTON      Pushbutton.
 
  DLGC_RADIOBUTTON     Radio button.
 
  DLGC_WANTALLKEYS     All keyboard input.
 
  DLGC_WANTARROWS      DIRECTION keys.
 
  DLGC_WANTCHARS       WM_CHAR messages.
 
  DLGC_WANTMESSAGE     All keyboard input (the application passes this
                       message on to control).
 
  DLGC_WANTTAB         TAB key.
