Error Handling Discussion

[eluser]Jim Higgins[/eluser]
I'm really trying to wrap my head around the process of error handling and proper user feedback for errors. Can anyone point me towards some good resources, examples, posts, or help explain the "rules" or best practice?

I'm curious as to when and where I should use try/catch statements? And the proper syntax for using them?

Additionally, I'm curious as to where/how to show error messages for the user when combined with the above try/catch statements?

Just to preclude the standard response "See the Error Handling" class... Thank you for that response in advance. I'm looking to expand the discussion and see some more in-depth usage and handling by others.

For example, when I say "where" above, I'm referring to things like: "I like to put them in my model whenever I do this... and this is how I do it. Then I throw the user a message like... and this is how I do it... etc, etc, etc"

Thanks
