[Shanthini Ganesh]

HI. Any One already fix this following problem? I have to upload a swf banner for my site at runtime. I have tried with FTPwebrequest class. The complete code here..

btnUpload_click()
{
string FtpUrl = "ftp://sitename/httpdocs/banner/BANNER.swf";
     string filename = "fuBanner.PostedFile.FileName";
 
        FtpUpload objFtpUpload = new FtpUpload();
          try
           {
             objFtpUpload.Upload(filename, FtpUrl, "UserName", "Password");
             lblmsg.Text = "Uploaded";
        }
          catch(Exception ex)
   {
             lblmsg.Text =ex.Message;
         }
      }
 
 
public class FtpUpload
{
    public void Upload(string filename, string FtpUrl,string UserName,string Password)
    {
        FileInfo fileInf = new FileInfo(filename);
        FtpWebRequest reqFTP;
        reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(FtpUrl));
 
 
        reqFTP.Credentials = new NetworkCredential(UserName,Password);
 
 
        reqFTP.Proxy = null;
 
 
        reqFTP.KeepAlive = false;
 
        reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
 
 
        reqFTP.UseBinary = true;
 
 
        reqFTP.ContentLength = fileInf.Length;
 
 
        int buffLength = 2048;
        byte[] buff = new byte[buffLength];
        int contentLen;
 
 
        FileStream fs = fileInf.OpenRead();
 
 
 
        Stream strm = reqFTP.GetRequestStream();
 
 
        contentLen = fs.Read(buff, 0, buffLength);
 
 
        while (contentLen != 0)
        {
 
            strm.Write(buff, 0, contentLen);
            contentLen = fs.Read(buff, 0, buffLength);
        }
 
 
        strm.Close();
        fs.Close();
 
 
    }
}

In the above code working well in local host. But When try to upload banner through webpage(that means from ftp site) it throws an exception as Could not find file .ie try to upload d:\\banner.swf. it throws exception Could not find file "D:\\Banner.swf". i think it couldnt identify client machine path .(loacl machine path). i need to upload from the website only. how to fix this problem...
