windows-8.1

问题 I'm developing a Windows 8.1 App (XAML/C#) with MVVM Light. I used to keep my LiveId inside the code just for debugging, but now it's time to do the LogIn. Currently i'm stuck with this piece of code: this.authClient = new LiveAuthClient(); LiveLoginResult loginResult = await this.authClient.InitializeAsync(scopes); It keeps giving me the error: An exception of type 'System.NullReferenceException' occurred in mscorlib.dll but was not handled in user code Additional information: Object

问题 Comboboxes in WinRT have a default ItemsPanel of type CarouselPanel. This gives Windows 8.1 apps an "infinite loop" when scrolling combobox items.

After upgrading to Windows 8.1 from Windows 8 today Apache isn't working anymore.

问题 I have added Microsoft Ad SDK to my WinJS app and it crashes if I navigate away from my default.html page too fast. <script src="/MSAdvertisingJS/ads/ad.js"></script> If I comment out this line it does not crash. If I navigate to the default.html page and wait 10 seconds (possibly less) then it does NOT crash. It only crashes if I land on the page and immediately navigate to another page in the app. I set the destination page to be a blank html page and it still crashes. Any ideas how I can

问题 I changed my Region/Location in my Windows 8.1 control panel to be South Africa. When I start up my app from Visual Studio 2013 and get the CultureInfo.CurrentUICulture it still says "en-US". public CultureInfo getCurrentCulture() { if (CultureInfo.DefaultThreadCurrentUICulture != null) { return CultureInfo.DefaulThreadCurrentUICulture; } else { return CultureInfo.CurrentUICulture; } } I've also tried CultureInfo.CurrentCulture instead of CurrentUICulture, but they are behaving the same way.

问题 I am trying to use matplotlib for real-time analysis from ECG-signals, but the problem starts even before. I use the PyCharm IDE, currently working with Python 3.3 and my os is Windows 8.1. For Matplotlib I downloaded matplotlib and the dependencies (numpy, six, dateutil, pyparsing, pytz) from here (the versions for Python 3.3): http://www.lfd.uci.edu/~gohlke/pythonlibs/ and installed it in the Python33 folder. Now if I try: from matplotlib.pyplot import plot, show plot(range(10)) show() or:

问题 guys, first time posting - I'm a newbie to Windows development and VS (Using 2013 on Windows 8.1). I've created a very simple application by the action of File->New Project/WPF application. The application works great, and does exactly what I'd like it to do. I successfully added a large (128x128) icon and got it to look great on Windows 7's taskbar and start menu by right-clicking my project in the Solution Explorer and specifying my .ico file through there. I also added the 'Icon' property

问题 I have an attached property I defined. namespace Controls { public class StateManager : DependencyObject { public static string GetVisualState(DependencyObject obj) { return (string)obj.GetValue(VisualStateProperty); } public static void SetVisualState(DependencyObject obj, string value) { obj.SetValue(VisualStateProperty, value); } // Using a DependencyProperty as the backing store for VisualStateProperty.
