  source

  <form id="form1" runat="server" enctype="multipart/form-data">
  <div>
  <asp:FileUpload ID="cmdSelectFile" runat="server" Width="544px" />
  <br />
  <asp:Button ID="cmdUpload" runat="server" Text="Upload" OnClick="cmdUpload_Click" />
  <asp:Label ID="lblMessage" runat="server"></asp:Label>
  </div>
  </form>

  .cs

  protected void cmdUpload_Click(object sender, EventArgs e)
  {
  try
  {
  if (cmdSelectFile.HasFile)
  {
  string fileExt =System.IO.Path.GetExtension(cmdSelectFile.FileName);
  FTWS ft = new FTWS();
  string tempFileName = ft.GetTempFilename();
  
  using (FileStream fs = new FileStream(cmdSelectFile.PostedFile.FileName, FileMode.Open, FileAccess.Read))
  {
  using (BinaryReader br = new BinaryReader(fs))
  {
  fs.Position = 0;
  int numBytesToRead = (int)fs.Length;
  int numBytesRead = 0;
  while (numBytesToRead > 0)
  {
  //I choose 100 000 bytes long blocks.
  byte[] b = br.ReadBytes(100000);
  ft.AppendToTempFile(tempFileName, b);
  if (b.Length == 0)
  {
  break;
  }
  numBytesRead += b.Length;
  numBytesToRead -= b.Length;
  //When block is saved, than we can update pbTransferStatus value
  int progressStatus = (int)((double)100 /
  (double)fs.Length * (double)numBytesRead);
  }
  ft.SaveFileIntoDatabase(cmdSelectFile.FileName, tempFileName, cmdSelectFile.PostedFile.FileName);
  lblMessage.Text = "File successfuly uploaded";

  }
  }
  }
  else
  {
  lblMessage.Text = "You have not specified a file.";
  }
  }
  catch (Exception err)
  {

  
  }
  }

  Here few methods in Webservie class . I think you can run without cs event.

  Thanks

  I checked your code with different kind of browser and your code is working only in "Internet Explore" and other then IE it is throwing exeception from below line

  using (FileStream fs = new FileStream(cmdSelectFile.PostedFile.FileName, FileMode.Open, FileAccess.Read))

  Why It is working in IE??

  Because IE is upload our selected file to temp directory of server first so you are able to do the FileStream using Name only, other then IE will not do such kind of opration, you have to SAVE the Uploaded file and then do the Menupulation which ever you wants

  Check below code for save the file

  cmdSelectFile.SaveAs("<<FileName>>");

  let me know if any query

  Thanks for your reply.

  Yes its working with InternetExplore  . I removed my code ( used new page with only upload controler) and open with Chrome . It has same problem .

  I t seems that controler is not supporting to chrome (  :(  not sure ) . And i used VS 2005  and chrome 18.0.1025.168 m version.
