Q&A

Q1:

If I am using both managed and unmanaged code, can I catch exceptions generated from either managed or unmanaged code?

A1:

It doesn't matter where the exception is thrown, if there is a try..catch block to handle the exception correctly. For example, if unmanaged code is called from managed code that is protected with a try..catch, the managed code will catch any exceptions it is looking for that are thrown by the unmanaged code.

Q2:

If I am using the Trace class, how do I turn off trace statements at runtime and turn them back on?

A2:

The .NET Framework provides the TraceSwitch class, which you can use not only to turn off trace statements but to turn them on with a filter for what level of trace statements you want to see. This is the elaborate solution; the other method is to simply remove the TraceListener from the Listeners collection.
