Randy,

One difference between C# and VB .NET is the VB .NET does not allow you to have events that return values. To get around this you need to change the delegate to a Sub instead of a Function.

>Hello all, I am converting some C# code to VB. I am having a problem with the code below. The design time debugger underlines the BeforeMessageEventHandler after Public Event. The error is
>Events cannot be declared with a delegate type that has a return type.
>Is the conversion wrong or does the code only work for C#. Thanks for the help.
