The FocusIn event occurs when the control receives the input focus.
Usually containers provide their own events which signal that a control receives or loses the input focus. Visual C++ applications can handle the WM_SETFOCUS and WM_KILLFOCUS Windows messages (OnSetFocus and OnKillFocus). For containers where such a facility is not available, the FocusIn and FocusOut events can be used instead. It is preferable to use events or mechanisms offered by the container rather than the FocusIn or FocusOut events.
Changing the input focus to another control or window while handling this event is not supported (including display of message boxes).
