You are creating a Windows application by using the .NET Framework 3.5. An existing ASP.NET application has the following specifications: The application is hosted on a server named SERVER1. Reports are built by using the Microsoft SQL Server 2008 Reporting Services (SSRS). The reports execute on SERVER1. User credentials are stored in a Microsoft SQL Server 2008 database. Users can view the reports after authentication to the ASP.NET application. The Windows application runs on a local computer. The reports that are used in the ASP.NET application are also applicable to the Windows application users. You need to design a reporting strategy to ensure that the Windows application displays the reports by using a MicrosoftReportViewer control. What should you do?

Set the ProcessingMode property to Local. Set the ServerReport.ReportServerUrl property to SERVER1. Call the ServerReport.ReportServerCredentials.SetFormsCredentials method by using the appropriate credentials. Set the ProcessingMode property to Local.Set the ServerReport.ReportServerUrl property to LOCALHOST. Call the ServerReport.SetDataSourceCredentials method by using the appropriate credentials. Set the ProcessingMode property to Remote.Set the ServerReport.ReportServerUrl property to SERVER1. Call the ServerReport.ReportServerCredentials.SetFormsCredentials method by using the appropriate credentials. Set the ProcessingMode property to Remote.Set the ServerReport.ReportServerUrl property to LOCALHOST. Call the ServerReport.SetDataSourceCredentials method by using the appropriate credentials.

You are creating a Windows application by using the .NET Framework 3.5. You build reports by using the Microsoft SQL Server 2008 Reporting Services (SSRS). The sales associates of the company execute the reports locally. Parameters are entered in a MicrosoftReportViewer control that calls a stored procedure to execute the report. The sales associates frequently report that the data returned on execution is not the most recent. You need to ensure that each time a report is executed, real-time data is displayed. What should you do?

Call the BindingSource.Clear method. Call the ReportViewer.DataBindings.Clear method. Call the ReportViewer.LocalReport.Refresh method. Delete the client report definition (RDLC) file by using the System.IO.File.Delete method.

You are creating a Windows application by using the .NET Framework 3.5. The application will be used to manage records of patients at the hospital. Each application form contains a TreeView control that displays a hierarchical list of patients. Items from the TreeView controls can be dragged to other controls on the form. Each form has a different layout. You discover that items from the TreeView controls of 10 forms cannot be dragged to other forms. You need to ensure that the TreeView controls across all forms in the application function appropriately. You want to achieve this goal by using minimum development effort. What should you do?

Create a user control that contains the TreeView control. Replace the TreeView control on each form in the application with the TreeView user control. Create a single base form that inherits the System.Windows.Forms.Form class.Add a TreeView control to the base form. Modify each form in the application to inherit the base form. Create a static class that contains a single method to create and return a TreeView control.Modify each form in the application to call the method. Add the TreeView control that is returned by the method to the controls collection of the forms. Use the Singleton pattern to create a class that contains all events to be raised by each TreeViewcontrol in the application. Modify each application form to subscribe to the events on the Singleton class instead of the TreeView controls. Set the TreeView controls to use the Singleton class to raise events.

You are creating a Windows application to manage customer relationships by using the .NET Framework 3.5. Users of the application access a form named FrmMain to view a list of contacts. When the user double-clicks the contact, the item details for the contact can be viewed on another form named FrmDetails. You need to ensure that the application meets the following requirements: A user can compare the details of multiple customers simultaneously. A user can rearrange all the open instances of the FrmDetails forms as a cascade or a tile in the FrmMain form. What should you do?

Create a new instance of the FrmDetails form for each contact. Call the ShowDialog method. Set the TopMost property of FrmMain to False. Create a new instance of the FrmDetails form for each contact. Call the Show method. Set the TopMostproperty of FrmMain to True. Set the IsMdiContainer property of the FrmMain form to True. Set the MdiParent property of theFrmDetails form to FrmMain. Set the IsMdiContainer property of the FrmDetails form to True. Set the MdiParent property of FrmMainto FrmDetails.

You are creating a Windows application by using the .NET Framework 3.5. The application is used to manage employee information. The application meets the following specifications: A main form named EmployeeList contains a list control that displays a list of all employees. The menu items help simultaneously display various detail forms for each employee selected from the list control. Each detail form for a selected employee contains a different set of information about the employee. You need to ensure that when a user switches from one employee to another, the open detail forms are updated to the corresponding employee information. What should you do?

Implement the INotifyPropertyChanging interface on the EmployeeList form. Add a static constructor to all detail forms and instantiate a PropertyChangingEventHandler delegate in all the static constructors. Add a public event named SelectEmployeeChanged to the EmployeeList form. Raise the event whenanother employee is selected from the list control. Subscribe to the SelectEmployeeChanged event in the constructor of all the detail forms along with a method that updates the information displayed on the form. Add a public static property named EmployeeId to all the detail forms.Implement the INotifyPropertyChanging interface on the EmployeeList form. Implement the INotifyPropertyChanging interface on each detail form. Add a public delegate named UpdateEmployee of the type EventHandler to the EmployeeList form.Create a method named UpdateInformation in all the detail forms. When a detail form is loaded, instantiate a new EventHandler delegate and point it to the UpdateInformation method. Assign this delegate to the UpdateEmployee delegate of the EmployeeList form. Invoke the UpdateEmployee delegate when another employee is selected from the list control.

You are creating a Windows application by using the .NET Framework 3.5. The application will be used for telephone directory management. The application has the following specifications: It stores data in a Microsoft SQL Server 2008 database instance. It uses the LINQ to SQL model. It stores the photograph of each directory member in the Picture column of the DirectoryEntry table. It displays the directory information in a DataGridView control. It supports expansion of rows of the DataGridView control to display the complete photograph of the directory member. The application is frequently used across remote or slow database connections. You need to implement the lazy load technique to load the photographs from the database. You also need to ensure that the implementation has minimum effect on the database connection. What should you do?

Configure the Picture property of the DirectoryEntry entity in the LINQ to SQL model. Set the Delay Loaded property to True. Identify the DataGridView column that contains the photograph. Set the Visible property of the columnto False. Identify the DataGridView column that contains the photograph. Set the Visible property of the column to True when the row that contains the photograph is expanded. Create a DataLoadOptions object in the method that is used to execute the LINQ query.Call the LoadWith method of the object along with the de => de.Picture statement. Use the DataLoadOptions object when the statement is executed. Modify the method that executes the LINQ query to accept a Boolean parameter which indicateswhether a photograph is to be loaded. Include a data-shaping clause to exclude the Picture column from the list of columns that are returned if the Boolean parameter is False. Execute the method initially by setting the Boolean parameter to True. Repeat the method execution by setting the Boolean parameter to False when the DataGridView row is expanded.
