    Hi all

    I had created a website and i am able to get backup of database on local system by this code

     protected void ImageBackup_Click(object sender, ImageClickEventArgs e)
            DatabaseBackup("C:/Program Files/MySQL/MySQL Server 5.5/bin/mysqldump.exe", "newpos");
            ClientScript.RegisterStartupScript(this.GetType(), "Key", "alert('Back up has been Successfully created on desktop')", true);
        } public void DatabaseBackup(string ExeLocation, string DBName)
                string tmestr = "";
                tmestr = DBName + "-" + DateTime.Now.ToShortDateString() + ".sql";
                tmestr = tmestr.Replace("/", "-");
                tmestr = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "\\" + tmestr;
                StreamWriter file = new StreamWriter(tmestr);
                ProcessStartInfo proc = new ProcessStartInfo();
                string cmd = string.Format(@"-u{0} -p{1} -h{2} {3}", "root", "root", "localhost", DBName);
                proc.FileName = ExeLocation;
                proc.RedirectStandardInput = false;
                proc.RedirectStandardOutput = true;
                proc.Arguments = cmd;
                proc.UseShellExecute = false;
                Process p = Process.Start(proc);
                string res;

    Access to the path 'C:\newpos-4-5-2013.sql' is denied.

    Ok. So either change the path, either let app pool user have access to the folder.
