问题 Does anyone know how to pass a url parameter to a local page in the Web Browser Control? When you navigate to the page alone "/Html/MyPage.html" all is well but as soon as you add a parameter "/Html/MyPage.html?Message=Hello" I get an error page stating that we could not navigate to the page.

问题 In Desktop Application or Web Projects projects there were App.configs and Web.configs files to store settings. These settings were set in development time (or whenever later) but if this occures, it was ALWAYS once action. In Windows Phone 8.1 XAML there isn't any App.config file, so developers are able to use Windows.Storage.ApplicationData.Current.LocalSettings . Nice. How can I set these settings first time (this means on first application run ever, so I can later only read them and

问题 I want to read certificate details (e.g. expiration date or CN) for security reasons. Usually there are some properties in network classes available, that allow to check the certificate. This is missing in WP8 implementations. Also I tried to create an SslStream but also there is no way to get any certificate detail like the RemoteCertificate on .net 4.5. var sslStream = new SslStream(new NetworkStream(e.ConnectSocket)); The SslStream is missing everything relating security.

问题 So Im now told that the FileSavePicker only creates a blank file, and that Ill have to write additional code to then actually write to the file. Ive started a Task WriteToFile after the FileSavePicker but Im unsure how to finish it. With the FileSavePicker, the user selects the folder they wish to save the file to.
