NEW QUESTION 6

The throw keyword is used to perform which two actions? (Choose two.)

• A. stop processing of the code
• B. move error handling to a separate thread
• C. raise exceptions
• D. re-throw exceptions as a different type

Answer: CD

Explanation:
* The Throw statement throws an exception that you can handle with structured exception-handling code (Try...Catch...Finally) or unstructured exception- handling code (On Error GoTo). You can use the Throw statement to trap errors within your code because Visual Basic moves up the call stack until it finds the appropriate exception- handling code.
* This example throws an ApplicationException exception. Throw New ApplicationException

You need to ensure the data integrity of a database by resolving insertion, update, and deletion anomalies.
Which term is used to describe this process in relational database design?

• A. Normalization
• B. Integration
• C. Isolation
• D. Resolution

Answer: A

• B. Set the Windows Service status to Paused.
• C. Implement the Console.WriteLine method throughout the Windows Service.
• D. Use the Attach to Process menu in Microsoft Visual Studio.

* Because a service must be run from within the context of the Services Control Manager rather than from within Visual Studio, debugging a service is not as straightforward as debugging other Visual Studio application types. To debug a service, you must start the service and then attach a debugger to the process in which it is running.
* To debug a service Install your service.
Start your service, either from Services Control Manager, Server Explorer, or from code. In Visual Studio, choose Attach to Process from the Debug menu.
