I have the same kind of app, with the next/previous picture buttons. And I had exactly the same memory leak, which has driven me mad. I still haven’t been able to find the root cause, but I’ve managed to bypass it with a ugly hack. When displaying the next picture, I force the old image … Read more
I finally found a solution that works for me. As I mention in the comment, Paul Stovell’s approach would not work. Instead I used a similar approach to add an attached property to the TextBlock, bound to the TextBlock’s DataContext, and attached properties on the runs, indicating which ViewModel properties they should be bound to: … Read more
For future reference , this worked for me ( I could not use additional query parameter due to project requirements) : HttpWebRequest request = HttpWebRequest.CreateHttp(url); if (request.Headers == null) { request.Headers = new WebHeaderCollection(); } request.Headers[HttpRequestHeader.IfModifiedSince] = DateTime.UtcNow.ToString();
It is easy to implement yourself, Unicode never messed with the ASCII codes: public static byte[] StringToAscii(string s) { byte[] retval = new byte[s.Length]; for (int ix = 0; ix < s.Length; ++ix) { char ch = s[ix]; if (ch <= 0x7f) retval[ix] = (byte)ch; else retval[ix] = (byte)’?’; } return retval; }
My RestSharp POST method: var client = new RestClient(ServiceUrl); var request = new RestRequest(“/resource/”, Method.POST); // Json to post. string jsonToSend = JsonHelper.ToJson(json); request.AddParameter(“application/json; charset=utf-8”, jsonToSend, ParameterType.RequestBody); request.RequestFormat = DataFormat.Json; try { client.ExecuteAsync(request, response => { if (response.StatusCode == HttpStatusCode.OK) { // OK } else { // NOK } }); } catch (Exception error) { … Read more
I add all that I found below. Please add if you know any more: STOCK APPS http:[URL] Launches the web browser and navigates to the specified URL. mailto:[email address] Launches the email app and creates a new message with the specified email address on the To line. Note that the email is not sent until … Read more
Well I can make the code you’ve got considerably simpler: public static byte[] ConvertToBytes(this BitmapImage bitmapImage) { using (MemoryStream ms = new MemoryStream()) { WriteableBitmap btmMap = new WriteableBitmap (bitmapImage.PixelWidth, bitmapImage.PixelHeight); // write an image into the stream Extensions.SaveJpeg(btmMap, ms, bitmapImage.PixelWidth, bitmapImage.PixelHeight, 0, 100); return ms.ToArray(); } } … but that probably won’t solve the … Read more
This is an extremely complex problem, and there is no simple solution here. There is no magic API that would just work for any app to solve this problem. The core problem with passing navigation data is Tombstoning. The only piece of data that is tombstoned by default is the Navigation URI. so if you’re … Read more
If simply put that your ItemsSource is bound like this: YourListBox.ItemsSource = new List<String> { “One”, “Two”, “Three” }; Your XAML should look like: <ListBox Margin=”20″ Name=”YourListBox”> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation=”Horizontal”> <TextBlock Text=”{Binding}” /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> Update: This is a solution when using a DataContext. Following code is the viewmodel you will be … Read more
If you write an XNA Game, you will have access to an explicit Exit() method. If you are writing traditional Silverlight project, then NO, there is no way to programatically close your app. See also Peter Torr’s Blog entry on Exiting Silverlight Apps in Windows Phone 7. There he also mentions the option of throwing … Read more
