q: how active document anywhere in application?

a: there several methods, 1 first active frame call cframewnd::getactivedocument. ... in mdi applications, have additionally active mdi child frame.

cdocument* getmdiactivedocument() {     cdocument* pdoc = null;      cwnd* pwndmain = afxgetmainwnd();     assert(pwndmain);     assert(pwndmain->iskindof(runtime_class(cmdiframewnd))); // not mdi app.      cframewnd* pframe = ((cmdiframewnd*)pwndmain)->mdigetactive();     if(null != pframe)     {         pdoc = pframe->getactivedocument(); // active document     }     return pdoc; }

this sample code might suggest other (perhaps better) alternatives:
