Do a project for five minutes without operation automatically jump back to the main interface, this will need to determine the form of the mouse time (form have N controls, and there is no click event web controls), could you tell me how to completely control form the mouse to click the event, as long as a click of the mouse response?

Global mouse control a lot of, can be searched,

The GetLastInputInfo function retrieves The time of The last input event.

Syntax

BOOL GetLastInputInfo (PLASTINPUTINFO plii
);
The Parameters

Plii
[out] Pointer to a LASTINPUTINFO structure that receives the time of the last input event.
The Return Value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.




Few

This function is useful for input idle detection. An GetLastInputInfo does not dojo.provide system - wide user input information across indicates all running sessions. Rather, GetLastInputInfo provides the session - specific user input information for only the session that invoked the function.

The Function Information

Minimum DLL Version user32. DLL
The Header Declared in Winuser. J h, include Windows. H
The Import library User32. Lib
Minimum operating systems, Windows 2000

This combination of three perfect solution...

Train of thought, according to the foreground window setfoucus detect whether the window has focus, start the timer if you have five minutes getlastinputinfo detection confirm input on how the operation, conversely, no

Setfocus killfocus, start the timer for 5 minutes not received focus to capture directly as a timeout, whereas the operating rights to the setfocus can

Some feel may still use GetLastInputInfo more appropriate, estimates that don't need that high authority,
