FoxPro declaration:

DECLARE INTEGER GetForegroundWindow IN user32

Return value:

The return value is a handle to the foreground window. The foreground window can be NULL in certain circumstances, such as when a window is losing activation.

Comments:

See the SetForegroundWindow function for more details about foreground windows.

Visual FoxPro 9.0 introduces the AppState property, which indicates whether the Visual FoxPro application has focus or not. _SCREEN.AppState returns 0 or 1.

Using the BindEvent() function you can easily detect when your Visual FoxPro application loses or receives focus.
