#define DLLIMPORT extern "C"_declspec (dllimport) DLLIMPORT LRESULT CALLBACK WndProc (HWND,UINT,WPARAM,LPARAM); and i plan on using this on the window creation... Wc.lpfnWndProc = WndProc; but how do i make on my other prog a wndproc function to be sent to the dll so it will use it on one export function "a window wrapper" ??? thx in advance
