Your Type string is likely invalid. It's format is:
"Type Name, Assembly Name" Assembly name format is: "Assembly Name[, PublicKeyToken][,Culture][,Version][,et cetera]" So unless your Type is called System.Diagnostics.TraceListener, you've specified the wrong type name.

[mailto:[EMAIL PROTECTED] On Behalf Of Ben Joyce Sent: Wednesday, August 23, 2006 10:31 AM To: [email protected] Subject: [ADVANCED-DOTNET] Creating a custom TraceListener... Hi all. I'm trying to write a TraceListener to log Debug.Write output into a database. I've made a simple class as follows: ----- 8<----- Public Class CustomListener Inherits System.Diagnostics.TraceListener Public Overloads Overrides Sub Write(ByVal Message As String) 'yadda End Sub Public Overloads Overrides Sub WriteLine(ByVal Message As String) 'yadda End Sub End Class ----- >8 ----- And I have added the following to my web.config file: ----- 8< ----- <system.diagnostics> <trace autoflush="true" indentsize="0"> <listeners> <add name="MyCustomListener" type="System.Diagnostics.TraceListener,CustomListener" /> </listeners> </trace> </system.diagnostics> ----- >8 ----- However, I'm getting an error when I try to do a Debug.Write: ----- 8< ----- An exception of type 'System.Configuration.ConfigurationErrorsException' occurred in System.dll but was not handled in user code Additional information: Couldn't find type for class System.Diagnostics.TraceListener,CustomListener. ----- >8 ----- Anyone got any ideas? Bit stumped here. =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
