Re: question about thunk

This thunk is ATL's way to hook your windows message handler, in the form of a non-static C++ member function, to all kinds of windows message(WM_*).

This is necessary because only a plain C function or static class member function is expected when you define a window class. 

So you have to find a way to disguise your member-function windows message handler as an acceptable plain C function or static class member function.

almost all modern OOP GUIs frameworks have to deal with this issue, but in different ways. MFC resorts to a window_handle-this_pointer map.
