interop

I'm making a COM interface that c# will be using, however i am wondering how i am to check for errors and exception handling on the c# end as at the moment i am just returning a HRESTULT or bool for most methods. But several things can go wrong in some of these methods and returning a E_FAIL just doesn't cut it.

What can i do in order to return more information? Can i make a HRESULT of my own?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

First, the background: I'm writing a Ruby app that uses SendGrid to send mass emails.
