You are creating a Windows Forms application. You add an ErrorProvider component named erpErrors and a DateTimePicker control named dtpStartDate to the application. The application also contains other controls. You need to configure the application to display an error notification icon next to dtpStartDate when the user enters a date that is greater than today’s date.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are creating a Windows Form that contains several ToolStrip controls. You need to add functionality that allows a user to drag any ToolStrip control from one edge of the form to another.
What should you do?

You are creating a Windows Forms application. You set the FlatAppearance.MouseOverBackColor property of a button to Blue. When testing the application, you notice that the background color does not change when you move the pointer over the button. You need to set the properties of the button so that the background color for the button changes to blue when the pointer moves over the button.
What should you do?

You want to execute an event handler asynchronously from a Windows Form. You need to write code that uses the BackgroundWorker component named bgwExecute to execute the WorkHandler method.
Which code segment should you use?

You are customizing a Windows Form to use a BackgroundWorker component named bgwExecute. bgwExecute performs a database operation in an event handler named WorkHandler. You need to ensure that users can see the progress of the database operation by viewing a progress bar named pbProgress. You want the progress bar to appear when the database operation is 50 percent complete.
Which code segment should you use?

You want to execute an event handler asynchronously from a Windows Form. You need to execute a method named WorkHandler by using an instance of the BackgroundWorker component named bgwExecute.
Which two code segments should you use? (Each correct answer presents part of the solution. Choose two.)

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 DoWorkEventHandler(WorkHandler);
bgwExecute.RunWorkerCompleted += new RunWorkerCompletedEventHandler(CompletedHandler);
bgwExecute.ProgressChanged += new
ProgressChangedEventHandler(ProgressChanged);
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?

You are customizing a Windows Form to asynchronously update a database. You need to ensure that the form displays a message box to the user that indicates the success or failure of the update.
Which three code segments should you use? (Each correct answer presents part of the solution. Choose three.)

You are customizing a Windows Form to asynchronously update a database in a method named WorkHandler. You need to ensure that the form displays a message box to the user that indicates the success or failure of the update.
Which code segment should you use?

You create a DirectorySecurity object for the working directory. You need to identify the user accounts and groups that have read and write permissions.
Which method should you use on the DirectorySecurity object?
