How to throw good exceptions?

Question

I heard you should never throw a string because there is a lack of information and you\'ll catch exceptions you dont expect to catch. What are good practice for throwing exc

Answer 1

I always throw an exception with a message of where it occurred and what caused it to happen:

throw NException("Foo::Bar", "Mungulator cause a stack overflow!");

You can then use these strings in messageboxes etc.

I always catch via

catch (NException& ex) { ... }

If you running windows you can pass the error value and have a function derive the error message. The best example of this is in Windows via C/C++ by Jeffrey Richter.
