How can I be notified when a new window is created on Win32?

Question

Is there a way using Win32, to register for notifications when a new window is created. I\'m trying to keep a list of current open windows, but am now just polling the list

You could try WinEventHook library for autohotkey. Try modifying the notepad popup blocker example with the following:

HookProc( hWinEventHook, Event, hWnd, idObject, idChild, dwEventThread, dwmsEventTime ) { if Event ; EVENT_SYSTEM_FOREGROUND = 0x3 {
WinGetTitle, title, ahk_id %hWnd% If (title = "your_window_name" msgbox, your window has been created } }
