Ah, sorry...

pointcut ini(CWnd* win) = that(win) && execution("int %::OnInitDialog ()");
advice ini(pWnd) : void before( CWnd* pWnd ) {...}

I didn't test, but I think that's it.

Perhaps it is a good idea to read a bit of the AspectJ documentation 
(www.aspectj.org). The semantics of the language is very close to AspectC++. 
They have many examples how to use pointcuts and how to expose context 
information from join points. Of course the syntax differs a bit.

I hope you will not switch from C++ to Java after this hint ;-). They have a 
version number > 1.0!
