Hi,

I'm want to upload a file to the webserver and rename it so it is the old file name + an id so that it won't get overwritten and I can associate it with the relevant record.  One of the overloads for the UpdateFile method has a parameter targetFileName which I hoped to use but it has no effect.  Am I missing something?  Please help.

Thanks

Hi,

Yes, this is what this is used for.  How have you implemented your web service, could you post the function declaration?

Thanks!

Hi Dan,

Thanks for your reply.  I've implemented almost exactly as the example.  Below is the code:

  /// <summary>

   /// Summary description for FileUploadService

   /// </summary>

   [WebService(Namespace = "http://tempuri.org/")]

   [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

   [System.ComponentModel.ToolboxItem(false)]

   public class FileUploadService : System.Web.Services.WebService

   {

      public FileUploadService()

      {

      }

      [WebMethod]

      public string Upload(string mode, string path, string name, string filedata, bool overwrite)

      {

         string fullpath = string.Empty;

         string filename = string.Empty;

         try

         {

            fullpath = Server.MapPath("~") + @"\" + path.Replace("/", @"\");

            filename = fullpath + name;

            if(!Directory.Exists(fullpath))

            {

               Directory.CreateDirectory(fullpath);

            }

            if (mode == "new")

            {

               if (File.Exists(filename))

               {

                  if (overwrite)

                  {

                     File.Delete(filename);

                  }

                  else

                  {

                     return "File Already Exists";

                  }

               }

               WriteFile(filename, Convert.FromBase64String(filedata), FileMode.Create);

            }

            else

            {

               WriteFile(filename, Convert.FromBase64String(filedata), FileMode.Append);

            }

         }

         catch (Exception ex)

         {

            File.Delete(filename);

            return "File Write Error: " + ex.Message;

         }

         return "ok";

      }

      [WebMethod]

      public void DeleteUploadedFile(string fileLocation, string fileName)

      {

         try

         {

            string strPathAndFile = Server.MapPath("~") + @"\" + fileLocation + fileName;

            if (File.Exists(strPathAndFile))

            {

               File.Delete(strPathAndFile);

            }

         }

         catch

         {

         }

      }

      private void WriteFile(string filename, byte[] content, FileMode fileMode)

      {

         Stream target = null;

         BinaryWriter writer = null;

         try

         {

            target = File.Open(filename, fileMode);

            writer = new BinaryWriter(target);

            writer.Write(content);

         }

         catch (Exception ex)

         {

            throw new Exception("Could not write to file: " + filename + " - " + ex.Message);

         }

         finally

         {

            if (target != null)

            {

               target.Close();

            }

            if (writer != null)

            {

               writer.Close();

            }

         }

      }

   }

Please help.

Hi Lance,

Apologies for this, the web service has changed and I think I have given you the wrong method stub, the Upload() method should have the following signature:

public string Upload(string id, string mode, string path, string name, string filedata, bool overwrite, string tag, bool final)

I have updated the download on the site to reflect this.  Could you give it a try and let me know if you still have problems?

Thanks!

Hi Dan,

Thanks for your help.  Changing the Upload signature helped me achieve my goal.  The "targetFileName" parameter still had no effect and didn't come through to the Upload function of the web service, but this time the "id" parameter came through and I was able to rename the file accordingly in the Upload function of the web service.  

Again, thanks for your help and your great controls.

Lance

Hi Lance,

I have modified the demo and integrated it with a test website.  This can be downloaded from the demos page as usual and should help point you in the right direction.

Thanks!
