You are working as an application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. Domain.com uses Visual Studio 2005 as an application platform. Domain.com consists of a Development department. You as the developer of Domain.com use a client computer named Certkiller -WS303 as developing guarantee.
You are busy writing a code to perform an asynchronous operation. You must adjust the priority of the thread that executes the asynchronous operation. The operation is must be specified to use input data from the main thread. What should you do to define the signature of the method that will contain the code to perform the asynchronous operation?

You were asked to use the BackgroungWorker component to do an asynchronous task.

What should you do to define the signature of the method that will contain the code to perform the asynchronous task?

You as the developer of Domain.com use a client computer named Certkiller -WS113 as developing collateral.
You are busy using a BackgroundWorker component to execute an asynchronous operation.
The job of the background thread is to call the ReportProgress method to update the foreground thread.
You have handled the ProgressChanged event and set the Value property of a ProgressBar.
The problem is that the ProgressBar display by no means gets updated. During the investigation you find out that the event handler that works with the ProgressChanged event never gets called.
What should you do to make sure that the event handler gets called?

You are busy using a BackgroundWorker component, set to its default value, to execute an asynchronous operation.
What should you do to receive notification when the operation completes?

ThreadStart threadStart = delegate

{
}
ParameterizedThreadStart parameterizedThreadStart = delegate[object args]
{
}
int threadPoolThreadCount = 0
Thread thread1 = new Thread[threadStart];
Thread thread2 = new Thread[parameterizedThreadStart]; Thread thread3 = new Thread[threadStart];
thread1.Start[];
thread2.Start[null];
thread3,Start[];
if [thread1.IsThreadPoolThread]
{
threadPoolThreadCount++;
}
if [thread2.IsThreadPoolThread]
{
threadPoolThreadCount++;
}
if [thread3.IsThreadPoolThread]
{
threadPoolThreadCount++;
}
What value of the threadPoolThreadCount should you identify after the code is executed?

You are busy using a BackgroundWorker component to call a method named DownloadJob in a background thread.
Which code segment is used to display a message box to alert the users when the background thread is complete?

You are busy using a BackgroundWorker component, set to its default value, to execute an

You are customizing a Windows Form to update a database asynchronously by using an instance of a BackgroundWorker component named bgwExecute. You start the component by using the following code.

private void StartBackgroundProcess() {
bgwExecute.DoWork += new Do WorkEventHandler(WorkHandler); bgwExecute.DoWorkerCompleted +=
new Do WorkerCompletedEventHandler(CompletedHandler); bgwExecute.ProgressChanged += new
ProgressChangedEventHandler(ProgressHandler);
bgwExecute.RunWorkerAsync();
}

If the UpdateDB method that is called by the BackgroundWorker component returns the
value False, you need to display a message box to the user that indicates that the update failed. Which code segment should you use?
