If any body wants rollover filename by date, try the below code. If they want to add time before write, then override WriteLine method also.

namespace CustomPackage

{

public class CustomTraceListener : TextWriterTraceListener

{

// for our constructors, explicitly call the base class constructor.

public CustomTraceListener(string fileName)

: base(CustomTraceListener.RollOverPath(fileName)) { }

public static string RollOverPath(string fileName)

{

System.DateTime _currentDate = System.DateTime.Today;

Assembly _callingAssembly = Assembly.GetCallingAssembly();

String assemblyName = Path.GetFileNameWithoutExtension(_callingAssembly.Location);

DateTime now = DateTime.Now;

string fileNameWithDt = Path.GetFileNameWithoutExtension(fileName);

fileNameWithDt = fileNameWithDt.Replace("[Assembly Name]", assemblyName);

fileNameWithDt = fileNameWithDt.Replace("[YYYY]", string.Format("{0:0000}", now.Year));

fileNameWithDt = fileNameWithDt.Replace("[MM]", string.Format("{0:00}", now.Month));

fileNameWithDt = fileNameWithDt.Replace("[DD]", string.Format("{0:00}", now.Day));

fileNameWithDt = Path.Combine(Path.GetDirectoryName(fileName),

fileNameWithDt + Path.GetExtension(fileName));

return fileNameWithDt;

}

This class is not using TraceListener capabilities..just inheriting, but not using any of the base class methods.

Wht is the use of extending System.Diagnostics.TraceListener

Ray,

See the logging block in MS Enterprise Library: http://www.codeplex.com/entlib. Whether you use that or log4net, there will be some learning curve and extra baggage involved.

Sometimes it is good to start simple with your logging (like in this post) then move to a framework when the need becomes apparent.

Where would your way be? I can find out who covers your area. Also, a good way to get involved with your local DE is to attend a .NET user group in your area.

Congrats!

I hope you're better than whomever has your job out my way. I've been developing with MS technologies for 7 years now and never heard of anything like this.
