.net - How to Detect a form open inside the application -

-

is possible detect when form opens inside application?

i have assembly used , initialized several applications. need use assembly detect, when form inside application opens, able modify it.

the solution found, yet, using messagefilter, edit: most efficient way getting notified on window open - ask windows in processes want windows in own process. since i'm interested in own application/process hope find sole .net solution.

application.addmessagefilter(new messagefilterimpl());  class messagefilterimpl : imessagefilter {     public bool prefiltermessage(ref message m)     {         control wnd= form.fromhandle(m.hwnd);         if (wnd form)             knownforms.add((form)wnd);          return false;     } }

i found first message receive 0xc052, still didn't find actual meaning.

the first intention choose better design, i'm not allowed to.
