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?

You use Visual Studio .NET to create an assembly, called XYZAssembly, that will be used by other applications, including a standard COM client application.

You must deploy your assembly on the COM application to a client computer. You must ensure that the COM application can instantiate components within the assembly as COM components.

What should you do?

You create an assembly by using Visual Studio .NET. The assembly is responsible for writing and reading order entry information to and from an XML data file. The assembly also writes and reads values to and from the Windows registry while it is being consumed.

The assembly will be distributed to client computers by using your company, XYZ, intranet. All client computers are configured to implement the default .NET security policy.

You need to implement security in the assembly. What should you do?

You use Visual Studio .NET to create a Windows-based application. The application includes a form named XYZProcedures (EXP). EXP allows users to enter very lengthy text into a database. When users click the Print button located on EXP, this text must be printed by the default printer.

You implement the printing functionality by using the native .NET System Class Libraries with all default settings.

Users report that only the first page of the text is being printed.

How should you correct this problem?
