Hi I am trying to upload an excel file to the server.
But it won't work, every time I am trying to upload an xls file and press the button. it writes: No file was uploaded.

as if i had no file. you are welcome to try on: http://radio.web.surftown.dk/admin/indset_program.aspx
the top section where you can upload a file from your computer

my code looks like this:

protected void Button2_Click(object sender, EventArgs e)
    {
        string sSavePath;

        sSavePath = "../";

        if (FileUpload.PostedFile != null)
        {
            // Check file size (mustn’t be 0)
            HttpPostedFile myFile = FileUpload.PostedFile;
            int nFileLen = myFile.ContentLength;
            if (nFileLen == 0)
            {
                lblOutput_excel.Text = "No file was uploaded.";
                return;
            }
            

            if (System.IO.Path.GetExtension(myFile.FileName).ToLower() != ".xls")
            {
                lblOutput.Text = "The file must have an extension of xls";
                return;

            }
           
            byte[] myData = new Byte[nFileLen];
            myFile.InputStream.Read(myData, 0, nFileLen);

            System.IO.FileStream newFile
                        = new System.IO.FileStream(Server.MapPath(sSavePath),
                                                   System.IO.FileMode.Create);
            newFile.Write(myData, 0, myData.Length);
            newFile.Close();
        
        }

                    

    }

Hope someone can help?

That means somehow your selected file is not been detected. Make sure that part works.

if (nFileLen == 0)
{
lblOutput_excel.Text = "No file was uploaded.";
return;
}

Do you get the same error message with other types of files or is this problem only when you try to upload and xls file? I wonder if this file type is not supported for some reason?

I just tried to upload a jpg file and it says exactly the same: No file was uploaded.
?

I got it to work now.
I just had to write:
sSavePath = "../test.xls";

instead of: sSavePath = "../
