# Create Log Files: ASP.NET VB, SQL 2005

Posted on 2011-09-28

I have created a console application as part of a data integration solution.  In my code, I'm currently writing errors to console.  I would like to create a text log file and write errors to it as well as the application completed time.

how do I create log files in vb.net?

Dim hQry2 As Integer = oAPI.AmQueryCreate(intConn)
If (hQry2 = 0) Then
Console.WriteLine("hQry2 = 0")  Write to a log file
End If

When you say "log files", are you referring to the Event Log, or just a flat text file?

Dim logFile As New System.IO.StreamWriter("yourPath\yourFile.txt", True)
logFile.WriteLine("hQry2 = 0")
logFile.Close()

You could also do it with one line. It is, of course, a matter of design and preference:
System.IO.File.AppendAllText("C:\path\to\log\file.txt", "hQry2 = 0")

There is cool log4net to write all types of log. You just need to configure and log the error

Check this.

I use NLog.  No need to re-invent the wheel per say as the dudes at NLog have done a phenomenal job with the library and allow you to do pretty much any type of logging you would want to.  Everything is setup in an NLog.config file.
