Throw new Excption ("bla, bla, bla")
....
Catch E as Exception
If E.Message.Equals("bla, bla, bla") Then ...
Mostly i just use the standard "Exception"-object whenever i throw an
exception, but it would be nice sometimes to make you own
"MyException"-object that you
can then easier Catch. using:
Catch Exp as MyException
....
Whenever i use the standard exception-object i check to see if the E.Message
equals the one i made, but since this isn't a very good way of coding, so
how do i make my own Exception-object. Do i need to make a new class that
inherits/implements from the Exception.class, or is there a way to do it
without starting making a exception-class for each object you want a
specialized exception for. Someting you do when you trow the exception for
example? 3 3170

Has been discussed here in the past days. See subject "Error handling -
custom 'throw?'"

This depends on various aspects:
* If there is already an appropriate exception class defined in the
.NET Framework, I would use this class instead of creating a new
class.
* If there is no class available in the .NET Framework, I would create
a custom exception class in order to make it easier to handle the
exceptions of a certain type.
Notice that it doesn't make sense to create a new exception class for
each exception -- sometimes it's better to use the same exception class,
for example, 'IOException'.

Jarod,
In addition to the other comments.
These are the guidelines that I try to follow: http://msdn.microsoft.com/library/de...Guidelines.asp
The following article provides a good template for defining well-tempered
exceptions: http://msdn.microsoft.com/library/de...rp08162001.asp
Although the code is in C# it should be easily converted to VB.NET. Catch E as Exception If E.Message.Equals("bla, bla, bla") Then ...
Did you know you can use a When clause here?
Try
Catch ex As Exception When ex.Message.Equals("bla, bla, bla")
Catch ex As Exception When ex.Message.Equals("alb, alb, alb")
End Try
Hope this helps
