You are creating a Windows Forms application that implements a master/detail form by using two DataGridView controls. You populate a dataset with a master table and a details table. You set the DataSource property of the master DataGridView control to the dataset. You set the DataMember property to the name of the master table. You also set the DataSource property of the details DataGridView control to the dataset. You need to ensure that the details DataGridView control displays only the child rows of the selected master row. What should you do?

You have received instructions to create a DataSet diagram that models a one-to-many relationship between patients and treatments as seen in the exhibit:

When you serialize instance of the created DataSet component you, you received the following XML:
<Patient>
<PatientID> 100</PatientID>
<PatientName>Amy Good</PatientName>
</Patient>
<Treatment>
<TreatmentID> 1000</TreatmentID>
<PatientID> 100</PatientID>
<Code>DTP</Code>
</Treatment>
The XLM should be as follows
<Patient>
<PatientID> 100</PatientID>
<PatientName>Amy Good</PatientName>
<Treatment>
<TreatmentID> 1000</TreatmentID>
<Code>DTP</Code>
</Treatment>
</Patient>

What should you do to change the dialog box so that the XLM in generated correctly?

A Windows Forms application loads an XmlDocument from a file named books.xml. You need to validate the XML against a schema that is contained in the books.xsd file when the XML loads. What should you do?

You are busy developing a custom control from a class from Control, which is not a composite control and performs all of its rendering by using GD+. What should you do to make sure that portions of the control are automatically repainted when a specific property changes?

You are testing an installation package for a Windows Forms application. You notice that the installed application will not run on client computers that do not have the .Net Framework installed. You need to ensure that when a user installs the application on his or her client computer, the .Net Framework is also installed. What should you do?

You are creating a data-entry application that uses many TextBox controls. Each control requires special validation logic. You need to ensure an extended version of the standard Windows Forms TextBox control that has the validation logic built into the control. You start by creating a new Windows Control Library project. What should you do?

You are busy to develop a Microsoft Windows Forms application that performs long- running task that performs in the background thread. The application is of such a kind, that it does not interoperate with Component Object Model {COM}.
What should you do to configure the application so that the background thread can report the status of the task by calling the ReportProgress method of the BackgroundWorker class?
