After You enter try { cmd.ExecuteNonQuery(); } catch(Exception ex) { FileStream fs; StreamWriter sw; fs = new FileStream("practice.txt", FileMode.Open ); sw = new StreamWriter(fs); // write a line to the file //In this line you concatenate the data string newLine = "Not so different from you and me"; sw.WriteLine(newLine); // close the streams sw.Close(); fs.Close(); }

How to achieve it? thanks in advance

Whether you are entering the values in the textboxes(Roll No) for updating the records.

hai, here i am updating 100 records at the same time. when the update fails, the record is to store in a log file (.txt). how to implement.? FOR EXAMPLE............. try { for (i=1;i=5;i++) { int a=i; sqlinsert="update tbl_name set loop_no=a where rollnumber=a"; cmd = new SqlCommand(sqlinsert, conn); } } catch(SqlException ae) { strreturn += "<br>Message: " + ae.Message.ToString(); } How to capture the failure records for the above UPDATE statement? HELP ME! i m using ASP.NET with C# (.net 2005, 2.0 framework)
