Hello,

I m woking on a web application that logins on another website and then downloads some files from that site just on a click of a button.

I have already implemented the logic to login on that website and am also able to see the protected page of that site.

Now that website is returning an HTML code that has the filename i want to download under <script> tag

<script>PrintFileURL("13572_BranchInformationReport_2012-05-22.zip","13572_BranchInformationReport_2012-05-22.zip",0,"184601","May 22 1:30","/icons/default.gif")</script>

the method called is

C#

function PrintFileURL(uri, name, dirFlag, filesize, time, icon)
               {
                    var color
                    var bgcolor
                    if(!(name.length>2 && name.charAt(name.length-1)=="e" && name.charAt(name.length-2)==".")) {
                         if (lineColor)
                         {
                              bgcolor="EEEEEE"
                              lineColor=false
                         }
                         else
                         {
                              bgcolor="FFFFFF"
                              lineColor=true
                         }
                         document.write("<tr bgcolor=" + bgcolor + ">");
                         if (dirFlag)
                         {
                              document.write("<td nowrap=""><img src='" + icon + "'><a href="" + uri +<br mode="hold" />                                   "/?T"> " + name + "</a></td>");

                                   "</font></td>");
                              document.write("<td><font face="Arial" size="2">" + time +
                                   "</font></td>");
                              document.write("<td> </td>");
                         }
                         document.write("</tr>");

Here you see the code

C#

public void downloadFile(string Url, string filePath)
       {
           if (File.Exists(filePath))
           {
               File.Delete(filePath);
           }
           //Downloading file form Http Url
           WebClient myWebClient = new WebClient();
           myWebClient.DownloadFile(url, filePath);
           //CompleteDownloading file form Http Url

}

In the above code ,In place of url=,"13572_BranchInformationReport_2012-05-22.zip",0,"184601","May 22 1:30","/icons/default.gif" and in filepath put the path to save the download file
