The Exception Assistant, which appears whenever a run-time exception occurs in the debugger, shows the type of exception, troubleshooting tips, and corrective actions that may be applied through the Exception Assistant.

An exception is an object that inherits from the Exception class. An exception is thrown by code whenever a problem occurs; it is passed up the stack until the application handles it or the program fails.

Note
