Use the System.IO.File object to create the file. The easiest way to get the values from the listbox is to copy the values to an array and string.join them to a csv string. Nowadays I store all data as xml which may be a bit more complicated but it pays off. This should handle your situation... ---------------------------------------------- using System.IO; using System.Text; using System.Windows.Forms; public class SaveFile { public SaveFile(ListBox list string FilePath) { string[] s = GetValues(list); if (s != null) { string values = string.Join( s); AppendToFile(values+
 FilePath); } } private string[] GetValues(ListBox list) { string[] s; s = new string[list.SelectedItems.Count]; for(int i=0;i<list.SelectedItems.Count;i++) s[i] = list.SelectedItems[i].ToString(); return s; } private void AppendToFile(string text string FilePath) { ASCIIEncoding enc; FileStream fs; byte[] stringToBytes; enc = new ASCIIEncoding(); fs = new FileStream(FilePath FileMode.Append FileAccess.Write); stringToBytes = enc.GetBytes(text); fs.Write(stringToBytes 0 stringToBytes.Length); fs.Close(); } } Enjoy!

Hi well never used this but got some idea.. firstly you cud get all text from ur listbox within a string and save it in a file...for this u need to create the file and open it in read/write mode... then scroll to the end of the file and append ur string... secondly u say its log info of the operations... for this u cud directly save the logging info into the file instead of the listbox... irfan
