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?
technology programming languages

  1. Set the RowFilter property of the DataView object to "BackOrder = True".

  2. Set the RowStateFilter property of the DataView object to "BackOrder = True".

  3. Set the Sort property of the DataView object to "BackOrder = True".

  4. Set the ApplyDefaultSort property of the DataView object to True.

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?
technology programming languages

  1. In the BeginPrint event, set the HasMorePages property of the PrintEventArgs object to True.

  2. In the EndPrint event, set the HasMorePages property of the PrintEventArgs object to True.

  3. In the PrintPage event, set the HasMorePages property of the PrintPageEventArgs object to True.

  4. In the QueryPageSettings event, set the HasMorePages property of the QueryPageSettingEventArgs object to True.

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?
technology programming languages

  1. to use the Windows user logon when connection to the TestKing1 database.

  2. to use the SQL Server used login when connection to the TestKing1 database.

  3. to use the same application logon ID and password for every connection to the TestKing1 database.

  4. to use the guest login ID and password for every connection to the TestKing1 database.

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?

technology programming languages

  1. Set the RightToLeft property of each control on the form to Yes.

  2. Set the RightToLeft property of the form to Yes.

  3. Set the Language property of the form to the appropriate language.

  4. Set the Localizable property of the form to True.

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?

technology programming languages

  1. Create

  2. Initialize

  3. Load

  4. New

Show answer
Correct Option: D

AI Explanation

To answer this question, you need to understand the purpose of each public procedure in the ContactABC class. Let's go through each option to understand why it is correct or incorrect:

Option A) Create - This option is incorrect because the "Create" procedure is not a valid public procedure in the ContactABC class.

Option B) Initialize - This option is incorrect because the "Initialize" procedure is not a valid public procedure in the ContactABC class.

Option C) Load - This option is incorrect because the "Load" procedure is typically used to load data or perform initialization tasks when a form is loaded, not when the ContactABC class is instantiated.

Option D) New - This option is correct because the "New" procedure is a valid public procedure in the ContactABC class. It is called when a new instance of the ContactABC class is created, allowing you to initialize class-level variables at that time.

The correct answer is D) New. This option is correct because it allows you to initialize all class-level variables in ContactABC as soon as it is instantiated.
