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
