You can create an instance of the Thread class to provide more control over background threads than is available using ThreadPool.QueueUserWorkItem. Define the Thread.Priority property if you want to run the thread using a priority other than Normal. When the thread is configured, call Thread.Start to begin processing. If you need to stop the background thread, call Thread.Abort. If you might abort a thread, you should catch ThreadAbortException in the method to allow the method to close any open resources. If your foreground thread needs to monitor background threads, you can check the Thread.ThreadState property. When using the Thread class, the easiest way to pass data to a method is to create an instance of the class containing the method, and define attributes of the class. To pass data from a thread, define a callback method. Often, multiple threads need access to the same resources. To minimize resource conflicts, use Monitor locks to allow only a single thread to access a resource. If you want to provide separate logic for read locks and write locks, create an instance of the ReaderWriterLock class. To prevent basic mathematical calculations from being corrupted in multithreaded environments, use the static methods of the Interlocked class. The simplest way to wait for a thread to complete is to call Thread.Join. To wait for multiple threads to complete, create an array of AutoResetEvent objects, pass one item to each thread, and then call WaitHandle.WaitAll or WaitHandle.WaitAny from the foreground thread.

Understanding the Allow Design Changes property Microsoft Access 2000 introduced a feature to allow you to further modify the design of your forms even while you are in Form view. You can set the Allow Design Changes property of the form to All Views. This lets you open the property sheet while in Form view to make additional design changes, as shown in Figure 11-20. All new forms in Access have the Allow Design Changes property set to All Views by default. You should be sure to set this property to Design View Only before using any form in a finished application.
