WPF idle application freezes
-
Hi, I'm developing a WPF application that seems to work fine, but after an long inactivity period, when the user clicks something it freezes for a while then it runs normally. This is the only application running in that computer, so I don't know what could be causing this. In my application I need to check the time between user clicks so I'm intercepting Windows messages like this:
void Window_Loaded(object sender, RoutedEventArgs e) { ResetTimeoutChecker();//reset the timer that does something HwndSource source = HwndSource.FromHwnd(new WindowInteropHelper(this).Handle); source.AddHook(new HwndSourceHook(myWndProc)); } private static IntPtr myWndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled) { if (msg == 0x0201)//if is a click then reset the timer that does something ResetTimeoutChecker(); return IntPtr.Zero; } -

Since the Window will "see" the event before it happens, you can perform you checks there. Then you can remove all the above code.
