The
WM_SETFOCUSmessage is sent to a window by the Windows system, as the result of a call toSetFocus()or the user setting the focus to the window by mouse or keyboard. Thus option 2 is the correct way to do it.Unrequited desire is character building. OriginalGriff I'm sitting here giving you a standing ovation - Len Goodman

Just look at the description of SetFocus(): http://msdn.microsoft.com/en-us/library/windows/desktop/ms646312%28v=vs.85%29.aspx[^] By reading that, you'll see that SetFocus() does a number of calls to make sure the focus is set correctly (kills the previous focus, activates the parent window of the control).
