I've never had the need to write a trace listener, but I can tell you the reason for your error. > Public Class CustomListener This class is compiled into an assembly. > <listeners> > <add name="MyCustomListener" > type="System.Diagnostics.TraceListener,CustomListener" /> You need to reference your class in this line. The format is described by Type.AssemblyQualifiedName in MSDN. The most important bits are the assembly and type - here you've said that CustomListener is located in an assembly called System.Diagnostics.TraceListener. That's why you get the exception you do. You should probably have something more like: type="My.Namespace.Here.CustomListener" if the type is declared in the executable, or something like: type="MyAssembly,My.Namespace.Etc.CustomListener" if the type is declared in MyAssembly.dll, etc. You may need to add extra qualifications as needed to the type. You can find the full type name by writing typeof(CustomListener).AssemblyQualifiedName to the console, or whatever the VB equivalent is. -- Barry -- http://barrkel.blogspot.com/ =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
