问题 I'm developing a Windows Phone 7 app but don't want to re-implement my own identity / authentication service - espcially when we know the user will be signed in with a Windows Live account. But, I understand from this thread that Microsoft will not be granting access to the logged in users details. Really? Is there a way to get this information from the Windows Live Id Service? Are there any api's that work on the device? Thanks, 回答1: It's true that the Windows Live ID will not be available

问题 I am attempting to help a user log into their account using a custom WebBrowser control. I am trying to set the value of an input tag to the players username using the WebBrowser 's InvokeScript function. However, my current solution is doing nothing but rendering a blank white page.

问题 It seems that .NET Compact Framework does not include a Proxy property for HttpWebRequest. Is there anyway, I can use proxy when reading from a HttpWebRequest? 回答1: No this is not currently possible to do it programatically from within your application. In windows proxy settings are configured in internet explorer. On the phone you can configure proxy settings from Edit Network inside Settings, if you do this and you are connected to a WiFi network it will make the connection go via the proxy

问题 string url = re["response"][0]["url"].ToString(); MediaElement mm = new MediaElement(); mm.Source = new Uri(url,UriKind.RelativeOrAbsolute); mm.AutoPlay = true; mm.Volume = 0.7; mm.Play(); But no changes, the adudio not starts.How I can resolve this? 回答1: You need to add your MediaElement to your VisualTree before playing it, since you're creating it in the codebehind.

问题 This question already has an answer here : How to pass values (parameters) between XAML pages? (1 answer) Closed 5 years ago . Passing value to another xaml page can be done easily with NavigationService.Navigate(new Uri("/SecondPage.xaml?msg=" + textBox1.Text, UriKind.Relative)); But that is only for string values. I would like to pass an object to the xaml page. How do I do that? Found a similar question on SO and WP7 forum. The solution is to use a global variable (not the nicest solution)

问题 Is there any PDF-viewer control which can be used in a Silverlight for Windows Phone 7 application? I've found this thread: Silverlight 4.0 PDF Viewer and tried PDFTron's SilverDox but I didn't have any luck because my application crashes with the exception: WindowsPhonePanoramaApplication1.dll!WindowsPhonePanoramaApplication1.App.RootFrame_NavigationFailed(object sender, System.Windows.Navigation.NavigationFailedEventArgs e) Line 109 + 0x5 bytes C# ..which is quite strange, I think. However,

问题 Microsoft recently released tools and documentation for its new Phone 7 platform, which to the dismay of those who have a big C++ codebase (like me) doesn't support native development anymore. Although I've found speculation about this decision being reversed, I doubt it. So I was thinking how viable would be to make this codebase available to Phone 7 by adapting it to compile under C++/CLI. Of course the user interface parts couldn't be ported, but I'm not sure about the rest. Anyone had a

问题 In my Windows Phone appllication I need to realize skype call to some users. Is it possible to call skype user from my Windows Phone application? 回答1: There is no built in support for this and no public SDK specifically for Windows Phone.
