  Copy shortcut operation with CRichEditCtrl in MFC
  
  I am very new to MFC. I am having following code for Copy and SelectAll shortcuts for CRichEditCtrl object.
  ON_COMMAND(ID_EDIT_COPY, OnCopy)
  ON_COMMAND(ID_EDIT_SELECT_ALL, OnSelectAll)
  
  But I am not able to catch breakpoint for Copy (Ctrl+C) and SelectAll (Ctrl+A) in the functions which I wrote here as It is not getting executed. 
  Here CRichEditCtrl object is read only(Text is for read and not allowed to modified).
  I also want to provide functionality of Text Selection with Mouse for CRichEditCtrl object. 
  Any idea on How to achieve this?
  
  A:
  
  This actions are not executed with a WM_COMMAND value we know. Also the keystrokes are checked internally and handled internally.
  Internally there are special window messages named WM_COPY and WM_PASTE for some actions that interact with the clipboard.
  Afaik the selection (Select all) is done completely internal. you can try to subclass the RTF control and intercept the EM_SETSEL message.
  If you want to intercept the keystrokes you can use PreTranslateMessage or you can again subclass the RTF control.
