Hi all

I wanna Backup from the SQL SERVER Database but I have the error :

<pre lang="c#">
private void BackUp(string strfilename)
{
 using (SqlConnection con = new SqlConnection(fis.connectstr))
           {
              
               string command = "BACKUP DATABASE Ast-db TO DISK='" + strfilename + "'";

               con.Open();
               using (SqlCommand cmd = new SqlCommand())
               {
                   cmd.CommandText = command;
                   cmd.Connection = con;
                   cmd.CommandType = CommandType.Text;
                   int r = cmd.ExecuteNonQuery();
                   if (r > 0)
                   {
                       MessageBox.Show("BackUp ok !!!!!!!!! ");
                   }
                   this.Cursor = Cursors.Default;
                   con.Close();
               }
}

Someone made changes to this thread, so it brought back to the top of "active questions".
