Throw up

[Bucky]

How do I throw an Exception in a method of a class and have it

travel upwards until it reaches an error handler? In other words,

I want the method to raise an error and the method's caller to

handle the error.

 

Currently I have the method call surrounded in a Try...Catch block,

but when I Throw the error in the method, the error occurs inside

the method itself.

 

If this isn't possible, should I just have an Error event and raise

the event when an error occurs?

 

Thanks

Perhaps I don't understand?

Public MySub()
 Try
     'do some processing that could throw an exception
 Catch ex As Exception
    Throw New Exception("Error in MySub",ex)
 End Try

End Sub

Is that what you're asking?

Ah, I hadn't thought about that, and that would work great for

the situation that I just described, I'm fairly sure.

 

But just now I realized that the description was incorrect... oops.

 

The sub that I'm throwing the error in is a sub that is called

asinchro-... asyncron-... asyncren-... uh, it's called async. :D

Anyway, it's a sub that's reading from a socket, so there's no

calling code of the sub to catch the exception.

 

I'll just set a protected string to the error description, and have

the main method that's called raise the error if the string contains

something.

 

Thanks Tim :)

Your question has given me the neat idea of calling all my exceptions "up" just so I can Throw Up in my code :)
