There’s lots of alternative as you’ve found out: WP7.5 Alarms & Reminders, WP7 Scheduled Tile updates, WP7.5 Periodic Background … Read more
You will need to store your images in the Isolated Storage and then display the images from there. I have put together a sample that you can download from the following location :- www.smartmobiledevice.co.uk/projects/webbrowserimagesample.zip This is based on the MSDN article How to: Display Static Web Content Using the WebBrowser Control for Windows Phone.
The WebClient only supports a single operations, it cannot download multiple files. You haven’t shown your code, but my guess is that you are somehow firing a new request before the old is completed. My bet is that WebClient.IsBusy is true when you attempt to perform another fetch. See the following thread: wb.DownloadFileAsync throw “WebClient … Read more
Afer looking at the source, for WP7 Hammock doesn’t actually use Json.Net for JSON parsing. Instead it uses it’s own parser which doesn’t cope with custom types very well. If using Json.Net directly it is possible to deserialize to a strongly typed collection inside a wrapper object. var response = @” { “”data””: [ { … Read more
You use the Headers property with a string index: request.Headers[“X-My-Custom-Header”] = “the-value”; According to MSDN, this has been available since: Universal Windows Platform 4.5 .NET Framework 1.1 Portable Class Library Silverlight 2.0 Windows Phone Silverlight 7.0 Windows Phone 8.1 https://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.headers(v=vs.110).aspx
You can always call an exit by doing this at your landing page use this code on click of your application back button: if (NavigationService.CanGoBack) { while (NavigationService.RemoveBackEntry() != null) { NavigationService.RemoveBackEntry(); } } This will remove back entries from the stack, and you will press a back button it will close the application without … Read more
The simplest method. In this particular case would probably be to go dynamic. dynamic data = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(json); var lastRevId = data.query.pages[“6695”].lastrevid; You can reference any element by it’s [] name so you can do something like data[“query”][“pages”][“6695”][“lastrevid”]. This will get by all those little objects where the name isn’t valid in c#.
What about trying: public static BitmapImage base64image(string base64string) { byte[] fileBytes = Convert.FromBase64String(base64string); using (MemoryStream ms = new MemoryStream(fileBytes)) { Image streamImage = Image.FromStream(ms); context.Response.ContentType = “image/jpeg”; streamImage.Save(context.Response.OutputStream, ImageFormat.Jpeg); return streamImage; } } I agree with Alexei that your code for reading the image in does look a little strange. I’ve recently written some code … Read more
In fact, it’s working, but it lacks some documentation. After some troubles, here’s how to use it : reference ImageTools reference ImageTools.Controls reference ImageTools.IO.Gif Add namespace in xaml : xmlns:imagetools=”clr-namespace:ImageTools.Controls;assembly=ImageTools.Controls” And resources : <phone:PhoneApplicationPage.Resources> <imagetools:ImageConverter x:Key=”ImageConverter” /> </phone:PhoneApplicationPage.Resources> Then use the control with the converter : <imagetools:AnimatedImage Source=”{Binding ImageSource, Converter={StaticResource ImageConverter}}” /> Your ImageSource should … Read more
