c++ - Hooking window creation in an MFC program -

i want hook window creation in mfc program.

is there way that?

use setwindowhookex install cbtproc.

here's sample code. call installhook() beginning of program, , monitor hcbt_createwnd notification code. can cancel window creation returning nonzero function, described in docs.

lresult callback mycbthook(int ncode,  wparam wparam,  lparam lparam) {     switch(ncode)     {     case hcbt_createwnd:         {             hwnd hwnd = (hwnd)wparam;             trace("a window being created, hwnd = %p\n", hwnd);             break;         }     }      return callnexthookex( 0, ncode, wparam, lparam ); }  void installhook() {     setwindowshookex(wh_cbt, mycbthook, 0, getcurrentthreadid()); }
