You are creating an ASP.NET page for selling movie tickets. Users select a region, and then they select from a list of cities in that region. The site displays the names and locations of movie theaters in the city selected by the user.

Your company, XYZ Brothers, maintains a list of theaters in a database table that includes the city, name, and street address of each theater. You want to minimize the time required to retrieve and display the list of theater names after a user selects the region and city.

 What should you do?

You are a member of a team of developers creating several ASP.NET applications for XYZ. You want to create a reusable toolbar that will be used in each of the applications. The toolbar will be displayed at the top of each page viewed by the user.

The contents of the toolbar will vary depending on options each user selects when creating a profile.

You want to be able to add the toolbar to the ASP.NET toolbox for each of the developers on your team.What should you do?

You create an ASP.NET application to provide corporate news and information to XYZ’s employees. The application is used by employees in New Zealand.

Default.aspx has a Web Form label control named currentDateLabel. The Page.Load event handler for Default.aspx included the following line of code:
currentDateLabel.Text = DateTime.Now.ToString(“D”)

You need to ensure that the data is displayed correctly for employees in New Zealand. What should you do?

You ASP.NET application manages order entry data by using a DataSet object named EXorderEntry. The EXorderEntry object includes two DataTable objects named orderNames and OrderDetails. A ForeignKeyConstraint object named orderDetailsKey is defined between the two DataTable objects.

You attempt to delete a row in orderNames while there are related rows in OrderDetails, and an exception is generated.What is the most likely cause of the problem?

You are a Web developer for XYZ. You create an ASP.NET application that accesses sales and marketing data. The data is stored in a Microsoft SQL Server 2000 database on a server named XYZ01.

The company purchases a factory automation software application. The application is installed on XYZ01, where it creates a second instance of SQL Server 2000 named Factory and a database named FactoryDB. You connect to FactoryDB by using Windows Integrated authentication.

You want to add a page to your ASP.NET application to display inventory data from  FactoryDB. You use a SqlConnection object to connect to the database. You need to create a connection string to FactoryDB in the instance of SQL Server named Factory on XYZ01. Which string should you use?

You are creating an ASP.NET page for a travel service. The page contains a CheckBoxList control that contains travel destinations. Customer can select favorite destinations to receive weekly e-mail updates of travel packages.

The CheckBoxList control is bound to a database table of possible destinations. Each destination is ranked according to its popularity. You modify the page to sort the destination list by rank, from the most popular to the least popular. The list has three columns.

You want the most popular destination to be on the top row of the check box list at run time. Which property setting should you use for the CheckBoxList control?

You develop an inventory management application called XYZManagement that will call a Microsoft SQL Server stored procedure named sp_GetDailyXYZSales. The stored procedure will run a query that returns your daily sales total as an output parameter. This total will be displayed to users in a message box.

Your application uses a SqlCommand object to run sp_GetDailyXYZSales. You write the
following code to call sp_GetDailyXYZSales:
SqlConnection cnn = new SqlConnection(myConnString);
SqlCommand cmd = new SqlCommand(“sp_GetDaily XYZ Sales”, cnn);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter prm = cmd.Parameters.Add(“@ItemTotal”,SqlDbType.Int);
prm.Direction = ParameterDirection.Output;
cnn.Open();
cmd.ExecuteNonQuery();

Now you must write additional code to access the output parameter. Which code segment should you use?

You develop an enterprise application, called XYZApplication that includes a Windows Form presentation layer, middle-tier components for business logic and data access, and a Microsoft SQL Server database.

You are in the process of creating a middle-tier component that will execute the data access routines in your application. When data is passed to this component, the component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction.

The code for the middle-tier component will implement the following objects:
SqlConnection cn = new SqlConnection();
SqlTransaction tr;

If two users try to update the same data concurrently, inconsistencies such as phantom reads will occur. You must now add code to your component to specify the highest possible level of protection against such inconsistencies.
Which code segment should you use?
