1: 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?
A.Add a foreign key constraint to the dataset.Set the DataMember property of the child DataGridView control to the name of the foreign key constraint.
B.Define a data relation between the master table and details table in the dataset.Set the DataMember property of the child DataGridView to the name of the data relation.
C.Add a foreign key constraint to the dataset.Set the DataMember property of the child DataGridView control to the name of the details table.
D.Define a data relation between the master table and details table in the dataset.Bind the details DataGridView control to the dataset.Set the DataMember property of the child DataGridView control to the name of the details table.
Correct Answers: B

2: You are creating a Windows Forms application. The application executes a stored procedure that takes several seconds to complete. The stored procedure is invoked to populate a SqlDataReader object. You need to ensure that the application remains responsive to the user while the stored procedure is executing. What should you do?
A.Use the SqlCommand.BeginExecuteReader method to call the stored procedure.Retrieve results by using the EndExecuteReader method.
B.Use the SqlCommand.ExecuteReader method.Set the behavior parameter of this method to CommandBehavior.SequentialAccess.
C.Create and bind a SqlDependency object to a SqlCommand object. Call the SqlCommand.ExecuteReader method.Associate an OnChanged event handler with the SqlDependency object. Gather results in the OnChanged event handler method.
D.Set the Notification property of a SqlCommand object to a SqlNotificationRequest object. Call the SqlCommand.ExecuteReader method.Gather results on a background thread.
Correct Answers: A

3: 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?
A.Associate the schema file with an XmlReader.Load the XmlDocument by using the XmlReader.
B.Add the schema to the Schemas property of the XmlDocument.Call the Load method of the XmlDocument by setting the filename parameter to books.xsd.
C.Call the Load method of the XmlDocument by setting the filename parameter to books.xsd, and then call the Load method by setting the filename parameter to books.xml.
D.Call the Load method of the XmlDocument by setting the filename parameter to books.xsd.Programmatically add the attribute xsi:schemaLocation to the root node. Set the value of this attribute to books.xsd.
Correct Answers: A

4: You are creating a Windows Forms application to retrieve and modify data. Depending on the installation, the data source can be a Microsoft Access database or a Microsoft SQL Server 2000 or later database. You need to ensure that your application accesses data by automatically using the data provider that is optimized for the data source.  What should you do?

B.In the User Interface Editor, add a Checkboxes dialog box to the Start node of the user interface tree.
C.Use the Custom Actions Editor to add the dialog box executable for the setup application to the Install node.
D.In the Properties window for your setup project, set the PreBuildEvent property to call a command line to display the dialog box.
E.In the File System Editor, set the Condition property for Help1 to the value of the Checkbox1Property property.Set the Condition property for Help2 to the value of the Checkbox2Property property.
F.Set the Checkbox3Visible and Checkbox4Visible properties of the Checkboxes dialog box to False.
Correct Answers: B E F

6: You are creating a setup project. You want to add functionality that will execute only if the setup project is executed by an administrative user.
