Message boxes from class libraries?

[MrNorth]

I have made a class library which is to be used with a winforms app. IN the class library I use message boxes to inform the user of any exceptions. But when creating a new winforms app, and begin using the classlibrary, the messageboxes won't show up, instead I get an unhandled exception. Am I thinking wrong here?

I think it is a bad idea to mix your UI with your dll unless you are aware of the consequences. What would happen when you try and use that dll for a web application?

Anyway, you should be able to see your form, as I have done it before. Can you post some code where you show it or if you get an exception post the ex.tostring()?

[MrNorth]

Gaah... yes you are right... of course I shouldn't mix those!!!!!

Any suggestions on what to return to the developer when there is an exception?

E.g. what should I do in the catch?

In the catch I usually throw up a new exception that has the original exception as it's inner exception and has my custom exception string that states what happened and may have some values for variables, etc.

I am curious as to how others might be handling this?
