Implementing copy/paste in a derived CWnd ?

Hello everybody,


I've derived a CMyWnd class directly from CWnd, and I'm using that class to display colored text in a IRC-style, using standard DC functions (TextOut, SetTextColor, ...).


Now, I'd like to implement a copy/paste functionnality within that class, but I really don't know how. Could anybody give me some example ?


Regards,
