You can't make a window like task manager. Only the OS can do that. – David Heffernan Nov 03 '17 at 07:10

Nothing that much wrong with SetWindowPos. Any kind of "my window is more important than any other" attitude, that's 97.2% of the time wrong. 99.9% when asked at SO. – Hans Passant Nov 03 '17 at 07:17

Two ways to make a window "top most".
When you create the window with CreateWindowEx, specify WS_EX_TOPMOST as an extended style.
CreateWindowEx(WS_EX_TOPMOST, ...);
For an existing window, use SetWindowPos:
DWORD flags = SWP_NOMOVE | SWP_NOSIZE;
SetWindowPos(hwnd, HWND_TOPMOST, 0,0,0,0, flags);
Either way is fine.

@selble DWORD dwType = GetWindowLongPtrW(hwnd, GWL_EXSTYLE); dwType |= WS_EX_TOPMOST; SetWindowLongPtrW(hwnd, GWL_EXSTYLE, dwType); SetWindowPos(hwnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE); – daijiepei Nov 03 '17 at 07:45
