We all make mistakes and when comes to programming I’m sure that I’ve made enough to fill an infinite loop array. Here is some sample code to help you create a customized Exception Handler class. Once again the Cognos SDK code is in C# for all of us .NET users.
using System;
using System.Web.Services.Protocols;
using System.Xml;
using System.Text;
