Problem with 'Microsoft.XMLHTTP' in javascript when i try to upload .wmv file to the Silverlight Streaming Service

Question

 

As per our requirement to upload .wmv file to the Silverlight Streaming Service directly from Client machine. I created a silverlight application that would upload file from client machine to the silverlight streaming server.I did not found Silverlight API that supports me to achieve this task with silverlight. Specially silverlight did not have System.Net.NetworkCredential to pass credentials to the WebClient / HttpWebRequest Object and also both classes not supported Http 'PUT' Method.So that I decided to select file from silverlight using OpenFileDialog, convert file stream into a string and pass it to a javascript function that upload it to the silverlight streaming server using Microsoft.XMLHTTP ActiveX object, because XMLHTTPRequest not supporting Cross Domain.But the problem I am facing is that file is partially uploaded to the silverlight streaming service. It is like to just create a file on server but not transferring complete file.Following is my code can someone help me.

 

 Silverlight application code in Page.Xaml.cs  

1    private void Upload_Click(object sender, RoutedEventArgs e)
2            
3    {
4                
5    var dialog = new OpenFileDialog();
6                
7    if (dialog.ShowDialog() == true)
8                
9    {
10   var input = dialog.SelectedFile.OpenRead();//getting input stream
11   byte[] fileBytes = new byte[input.Length];
12         int byteCount = input.Read(fileBytes, 0, (int)input.Length);
13                   //Reading Bytes
14   string fileContent = Encoding.Unicode.GetString(fileBytes, 0, (int)input.Length); //Encoding file content bytes to unicode
15   
16   var path = "https://silverlight.services.live.com/71289/DA/" + dialog.SelectedFile.Name;
17   
18   object[] param = new object[] 
19   { path, fileContent, dialog.SelectedFile.Name, dialog.SelectedFile.OpenRead().Length };
20   HtmlPage.Window.Invoke("sendDataToServer", param); // Calling a javascript method and pass values to upload on SLS Server
21                   
22   }
23   }
