  I am sorry. I have spent so long time to solve the problem but i still cant find it. Is there any problem for the while loop. I converted it to vb. but i found that it will skip the output.stream when it reach the while loop when i debug using debugger. What's the problem? i think the code is exactly same with the c#. But I am not understand why it would be different! its also the same in the generic handler. Please help :( Private Sub UploadFileData(ByVal strm As Stream, ByVal OutputStream As Stream) Try Dim fileData As Byte() = New Byte(4095) {} Dim fileDataToRead As Integer MessageBox.Show("UploadFileData") While ((fileDataToRead = strm.Read(fileData, 0, fileData.Length)) > 0) OutputStream.Write(fileData, 0, fileDataToRead) End While MessageBox.Show("UploadFileData Finish") Catch ex As Exception MessageBox.Show(ex.Message) End Try MessageBox.Show("Finish") End Sub

  Hello, I have a little question. when I deploy the solution to the "production server" this URL must change UriBuilder ub = new UriBuilder("http://localhost:3840/receiver.ashx"); How can I know the final production url of the handler??? Thanks

  Once I got through the handler permission dance, this sample worked 99% like a champ. I have one issue that it appears as if the file isn't closed properly when written to the server. I'm uploading WMV files for a Silverlight app ( already encoded ). Everything works great until playback, and the WMVs only play ~ 50%. Anybody have any suggestions of things I should look into? This is my first foray into uploading with Silverlight.

  Hey out there. I turned my relevant projects in my solution to static portnumbers... I just have a problem with the above link. My Handler looks like this: <%@ WebHandler Language="C#" Class="receiver" %> using System; using System.Web; using System.IO; public class receiver : IHttpHandler { public void ProcessRequest(HttpContext context) { string filename = context.Request.QueryString["filename"].ToString(); using (FileStream fs = File.Create(context.Server.MapPath("~/" + filename))) { SaveFile(context.Request.InputStream, fs); } } private void SaveFile(Stream stream, FileStream fs) { byte[] buffer = new byte[4096]; int bytesRead; while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) != 0) { fs.Write(buffer, 0, bytesRead); } } public bool IsReusable { get { return false; } } } Yes and my call looks like that: private string host = "localhost"; private string port = "64670"; private string app = "SensorVisual.Web"; ... private void UploadFile_Click(object sender, RoutedEventArgs e) { // Prompt the user to select an image file. OpenFileDialog ofd = new OpenFileDialog(); ofd.Multiselect = false; ofd.Filter = "XML File (*.xml)|*.xml"; if ((bool)ofd.ShowDialog()) { string name = "upload" + DateTime.Now.ToString("dd_MM_yy_hhmm") + ".xml"; UploadFileData(name, ofd.File.OpenRead()); } } private void UploadFileData(string fileName, Stream data) { UriBuilder ub = new UriBuilder("http://"+this.host+":"+this.port+"/"+this.app+"/receiver.ashx"); ub.Query = string.Format("filename={0}", fileName); WebClient c = new WebClient(); c.OpenWriteCompleted += (sender, e) => { PushData(data, e.Result); e.Result.Close(); data.Close(); }; c.OpenWriteAsync(ub.Uri); } But the problem is that it doesn't work. If I start my SL project it works, that I can open http://localhost:64670/SensorVisual.Web/receiver.ashx?filename=test.xml. That works pretty fine, it also creates the test.xml File. My problem is, that it isn't working with this function. Please could you help me? It's really urgent... Thanks for your help in advance! greets

  Jonathan17y agoPosted Aug 3, 2009, 10:00 AM

  Hi Nipan Very useful post - thanks I have an app displaying images from a file in the Silverlight App but as far as I can see your implementation only allows to write images to the asp.net app so: Read SL App file = Photos Write Asp.Net app file = More Photos How to get the Silverlight and Asp.net apps to write to and read from a common file?

  Nice article! We have extended on the open source projects out there, and created a new codeplex project with a stable, flexible, and well-documented silverlight file uploader that is based on similar techniques to those used in this article: http://silverlightuploader.codeplex.com/

  CodePlex has something interesting here. Silverlight file uploader that supports multi-file upload, resize images before upload with image thumbnail, individual progress and overall progress indicator, fast upload, ASP.NET server control, and is highly customizable. http://www.codeplex.com/SilverlightFileUpld

  I think SL3 has a built-in OpenFileDialog and SaveFileDialog controls. That would be cool.
