You use Visual Studio .NET to create an application that uses an assembly. The assembly will reside onthe client computer when the application is installed. You must ensure that any future applicationsinstalled on the same computer can access the assembly.Which two actions should you take? (Each correct answer presents part of the solution.

You develop a Windows Form that provides online help for users. You want the help functionality to beavailable when users press the F1 key. Help text will be displayed in a pop-up window for the text boxthat has focus.To implement this functionality, you need to call a method of the HelpProvider control and pass the textbox and the help text.Which method should you call?

You use Visual Studio .NET to develop a Windows-based application called ABCApp. Your application will display customer order information from a Microsoft SQL Server database. The orders will be displayed on a Windows Form in a data grid named DataGrid1. DataGrid1 is bound to a DataView object. The Windows Form includes a button control named displayBackOrder. When users click this button, DataGrid1 must display only customer orders whose BackOrder value is set to True. How should you implement this functionality?

You use Visual Studio .NET to create a Windows-based application. The application includes a form named TestKingProcedures (TKP). TKP allows users to enter very lengthy text into a database. When users click the Print button located on TKP, 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?

You develop a Windows-Based application that accesses a Microsoft SQL Server database named ABC. Users must supply a user name and password when they start the application. This information is then used to dynamically build a connection string. When you test the application, you discover that it is not using the SqlClient connection pooling feature. You must reduce the time needed to retrieve information. How should you modify the connection string?

You are preparing a localized version of a Windows Form named ABCLocal. Users of ABCLocal speak a language that prints text from right to left. User interface elements on the form need to conform to this alignment. You must ensure that all user interface elements are properly formatted when the localized Windows Form runs. You must also ensure that ABCLocal is easy to update and maintain. What should you do?

You develop a Windows-based application that contains a form named ContactABC. You need to write code to initialize all class-level variables in ContactABC as soon as ContactABC is instantiated. You will place your code in a public procedure in the ContactABC class. Which public procedure should you use?

You use Visual Studio .NET to create several Windows-based applications. All use a common class library assembly named ABCCustomers. You deploy the application to client computers on your company intranet. Later, you modify ABCCustomers.Any application that uses version 1.0.0.0 must now user version 2.0.0.0. What should you do?

You develop a Windows-based application ABCApp by using Visual Studio .NET. ABCApp uses a SqlConnection object for database access. You typically run ABCApp on a computer that has limited RAM and hard disk space. After the code finishes using the SqlConnection object, you must ensure that the connection is closed and that any resources consumed by the object are released immediately. What should you do?

You plan to develop a customer information application CustomABC that uses a Microsoft SQL Server database. CustomABC will be used frequently by a large number of users. Your application code must obtain the fastest possible performance when accessing the database and retrieving large amounts of data. You must accomplish this goal with the minimum amount of code. How should you design CustomABC?
