hi
any help plz?

[Momerath]

Lines 111-112 have a StreamWriter. Your request is vague. What does this StreamWriter you need to add need to write?

[Nyight]

The only thing I can think of would be the following as you want it wrapped in a using() statement though implementing a using() is very easy as below shows.

private void LogToFile(string FileName,string dataToSave)
{
   using(StreamWriter theString = new StreamWriter(FileName+".csv", true)))
   {
      theString.WriteLine(DateTime.Now+"\t"+ dataToSave+"\t\n");
      theString.Close();
   }
}

Hope this helps.
