If the question is clear, we can see you have made efforts to code the solution yourself, and you clearly state what is wrong and what you want to achieve, you won't get downvotes –Chris Ballard Mar 25 '14 at 11:02 ok sir. i will keep that in mind –user3458227 Mar 25 '14 at 11:07 No worries, StackOverflow isn't that scary, as long as you know the basics.

In those how to make situations, it is often helpful to have a simple routine that you can use to log messages to a text file for later analysis. Here’s a simple routine that has helped me a lot for example when writing server applications without an user interface: using System.IO; public string GetTempPath() { string path = System.Environment.GetEnvironmentVariable("TEMP"); if (!path.EndsWith("\\")) path += "\\"; return path; } public void LogMessageToFile(string msg) { System.IO.StreamWriter sw = System.IO.File.AppendText( GetTempPath() + "My Log File.txt"); try { string logLine = System.String.Format( "{0:G}: {1}.", System.DateTime.Now, msg); sw.WriteLine(logLine); } finally { sw.Close(); } } With this simple method, all you need to do is to pass in a string like this: LogMessageToFile("Hello, World"); The current date and time are automatically inserted to the log file along with your message.
