Re: question about thunk

Thanks for the prompt help.

I read the source code again, it's clear to me now that the thunk itself , not CWindowImplBaseT<>::WindowProc(), is set to be the wndproc of the window class by the following lines CWindowImplBaseT<>::StartWindowProc in :

WNDPROC pProc = (WNDPROC)&(pThis->m_thunk.thunk);
::SetWindowLong(hWnd, GWL_WNDPROC, (LONG)pProc);
