-- Moved from [aspngfreeforall] to [aspngdebug] by Charles M. Carroll <Click here to reveal e-mail address> --Do errors "bubble" up through the call stack in .NET? I'm somewhat new to "real" programming (only ASP and Basic before), so the whole error handling thing is unfamiliar to me.For example, if I create a function in a DLL that I access from a web project, if I use Try <call to DLL> Catch e as exception End Try, will I be able to catch any errors that happen inside of the DLL function?Thanks.--Ambrose

Yep, that's how it works. Of course, if the DLL is doing its own error handling
it might not throw exceptions (depends on how it is written), but assuming
that's not the case, you're right on about the process.

Yes, Exceptions certainly bubble-up, if they have not already been
caught!
If your Dll functions handle their exception's the exception will not
bubble-up, but if there is any un-handled exception in the Dll functions
they will bubble-up to the caller application... and if still its not
caught, the user will be presented with an appropriate error message and
the application might terminate!

Could I catch an error in my DLL and within the catch statement throw a
custom exception?

Certainly, in fact this is often done.
