...check, how long the system is Idle?
Author: Thomas Stutz
function LastInput: DWord;
var
LInput: TLastInputInfo;
begin
LInput.cbSize := SizeOf(TLastInputInfo);
GetLastInputInfo(LInput);
Result := GetTickCount - LInput.dwTime;
end;
//Example:
procedure TForm1.Timer1Timer(Sender: TObject);
begin
Label1.Caption := Format('System Idle since %d ms', [LastInput]);
end;
// The GetLastInputInfo function retrieves the time
// of the last input event.
// Minimum operating systems: Windows 2000
