Hi,

great work with the fileuploader component!

Anyway I need to upload a file from isolated storage and I don't know how to get the required FileInfo data for the UpdateFile method..

Alternatively I could use the UploadData method that needs a stream but I can't get it working..

I really would apprecciate an example for that.

So many thanks for your great job!

Best regards, Andrea.

Hi Andrea,

You can use the web service provided with the demo code, please download the latest version here, this will recieve your file.  If you have a Stream rather than a FileInfo object, yes, you need to use the UploadData method.

To use the UploadData method you will use:

_uploader.UploadData("myUpload", dialog.File.OpenRead(), dialog.File.Name, target, dialog.File.Name, true, "");

And your web service method stub will be:

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

Thanks!

Hi Dan,

thank you for your time.

Actually the WebMethod Upload I took from your example it never called when I try to invoke it from:

uplUploader.UploadData("myUpload", data, "hello", "target", "hello", true, "");

Notice I have a stream (data) from a memory stream and not from a dialog.

If I used the UploadFiles defining a convenient webmethod all works right. But I have to use the UploadData I guess, because I don't have data source from a user diaog.

I don't know where I'm wrong ...Thank you!

[WebMethod]

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

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

    {

        string filename = string.Empty;

        if (!path.StartsWith("documents/"))

        {

            return "";

        }

        name = System.Text.RegularExpressions.Regex.Replace(name, "[^a-zA-Z0-9 \\-\\._!]", "");

        if (name.EndsWith(".dll") || name.EndsWith(".ascx") || name.EndsWith(".aspx"))

        {

            return "";

        }

        try

        {

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

            if (mode == "new")

            {

                if (File.Exists(filename) == true)

                {

                    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";

    }

Okay, Passing data from a memory stream rather than the file dialog as in my example will work just the same.  I assume you have placed a breakpoint on your web service when testing and it is never called?

Looking at your web service it looks fine and if it is never called suggests the problem is with this Silverlight client and quite possibly the memory data stream, is it possible for you to post/email your full Silverlight or at least a test application that reproduces the problem?

Thanks!
