Asp.Net And SQL Basic 2

The correct answer is "DELETE FROM CUSTOMER WHERE ...". This command is used to remove rows from a table called 'CUSTOMER' based on a specified condition. The WHERE clause is used to specify the condition that must be met for the rows to be deleted. This command is commonly used in SQL to delete specific rows from a table.

Yes, it is possible to allow a class to be inherited but prevent the method from being overridden by using the "final" keyword in the method declaration. When a method is marked as "final", it cannot be overridden by any subclass. This allows the class to be inherited and used as a base class, but ensures that the specific method remains unchanged and cannot be modified in any subclass.

ASP.NET is a server-side scripting technology that allows developers to create dynamic web applications. It is used to generate HTML, XML, and other types of web pages that are sent to the client's web browser. This technology runs on the web server and processes the requests from the client, allowing for the execution of server-side code and interaction with databases. Unlike client-side scripting technologies, which run on the client's browser, ASP.NET executes on the server, making it a server-side scripting technology.

During the page load, the first method that is fired is the Init() method. This method is used to initialize the page and its controls. It is called before the page is loaded and before any control events are handled. It is typically used to set initial values, create dynamic controls, or perform any necessary setup tasks. Once the Init() method is executed, the page proceeds to the next stage of the page lifecycle, which is the Load() method.

The use of Debug and Trace commands includes monitoring, detecting malfunctions, and providing performance measurement information. Debug commands help in monitoring the execution of a program, allowing developers to track the flow of code and identify any errors or issues. Trace commands are used to detect malfunctions by providing detailed information about the program's execution, allowing developers to identify and fix any bugs or problems. Additionally, both commands can be used to gather performance measurement information, helping developers analyze and optimize the performance of their code. Therefore, the correct answer is "All of the Above."

A class must be declared as abstract when at least one of its methods is abstract. This is because an abstract method is a method that is declared without an implementation, and it must be overridden by any concrete subclass. Therefore, if a class has an abstract method, it cannot be instantiated directly and must be declared as abstract. However, if all the other methods in the class are abstract, it is not necessary to declare the class as abstract because the presence of abstract methods already implies that the class is abstract.

System.dll is a shared assembly. Shared assemblies are libraries or components that can be used by multiple applications on the same machine. They are stored in the Global Assembly Cache (GAC) and can be accessed by different applications, providing code reusability and reducing redundancy. System.dll, being a part of the system framework, is a shared assembly that contains common functionality and can be utilized by various applications.

A view is a virtual table that can be accessed via SQL commands. It is a logical representation of data from one or more tables in the database. Views can be used to simplify complex queries, provide restricted access to data, or present data in a different format. They do not store any data themselves but retrieve data from the underlying tables. Users can query a view using SQL commands just like they would query a regular table, and the view will return the desired results based on the defined logic.

Gacutil.exe is the correct answer for managing assemblies in the Global Assembly Cache (GAC). The Global Assembly Cache is a central location where shared .NET assemblies are stored on a computer. Gacutil.exe is a command-line tool provided by Microsoft that allows developers to install, uninstall, and view information about assemblies in the GAC. It provides functionality to add assemblies to the GAC, remove them, and display a list of assemblies currently installed.

The Common Language Specification (CLS) is a set of rules and guidelines that ensures language interoperability in the .NET Framework. It defines a minimum set of features and data types that all languages targeting the .NET Framework should support. By adhering to the CLS, developers can write code in one language and use it seamlessly with code written in another language within the .NET ecosystem. Therefore, the correct answer is Common Language Specification.

ASP.NET provides increased performance by running compiled code. When an ASP.NET application is deployed, the source code is compiled into a binary format, which allows the server to execute the code directly without the need for interpretation or just-in-time (JIT) compilation. This eliminates the overhead of compiling the code on the fly, resulting in faster execution and improved performance.

Truncate is the correct answer because it removes all rows from a table without logging the individual row deletions. Unlike the delete statement, truncate does not generate individual delete statements for each row, making it faster and more efficient for deleting all rows in a table. Additionally, truncate cannot be rolled back, so it is important to use it with caution as it permanently removes all data from the table.

The garbage collector in an application is responsible for reclaiming memory that is no longer in use. It runs randomly based on the resource load on the system. When the system is under high resource load, the garbage collector may run more frequently to free up memory. Conversely, when the system is not under heavy load, the garbage collector may run less frequently. This random scheduling allows the garbage collector to adapt to the current state of the system and optimize memory management accordingly.

The RangeValidator control supports three data types: Integer, String, and Date. This means that the control can validate input values that are integers, strings, or dates, ensuring that they fall within a specified range.

ASP.NET stores SessionIDs by default in cookies. Cookies are small pieces of data that are stored on the client's browser. When a user visits a website, the server sends a cookie to the client's browser, which then stores it. The cookie contains the SessionID, which is used to identify the user's session on the server. This allows the server to retrieve the session data for the user when needed. Storing SessionIDs in cookies is a common and convenient method as it does not require any additional configuration or setup.

The SQL WHERE clause is used to filter rows based on a specified condition. It allows us to retrieve only the rows that meet the specified criteria, thus limiting the row data that are returned. The WHERE clause does not have any effect on the columns that are returned, so the statement "limits the column data that are returned" is incorrect. Therefore, the correct answer is "limits the row data are returned."

A .Net web site is configured with anonymous authentication by default, which allows users to access the site without providing any credentials. Integrated Windows authentication is also configured by default, which allows users to authenticate using their Windows credentials. This combination ensures that the site can be accessed by both anonymous users and authenticated users using their Windows credentials.

The answer is "rows can either be inserted into a table one at a time or in groups" because the SQL INSERT statement allows for the insertion of multiple rows at once by specifying multiple sets of values to be inserted. This can be done by using a comma-separated list of values or by using a SELECT statement to retrieve data from another table and insert it into the target table. Therefore, it is possible to insert rows individually or in groups using the SQL INSERT statement.

The primary key is selected from the candidate keys. Candidate keys are the potential keys that can uniquely identify each record in a table. From these potential keys, one is chosen as the primary key. The primary key is a unique identifier for each record and is used to enforce data integrity and ensure the uniqueness of each record in the table.

ON UPDATE CASCADE ensures data integrity. When a row in the referenced table is updated, ON UPDATE CASCADE automatically updates the corresponding rows in the referencing table. This ensures that the integrity of the data is maintained across the tables.

The ObjectBrowser tool would be used to see all the methods of a particular class in the application. This tool allows users to navigate through the objects and classes in the application and view their properties and methods. It provides a comprehensive view of the structure and functionality of the classes in the application, making it easier for developers to understand and work with the code.

No, you do not need IIS to develop a web application in ASP.NET 2.0. ASP.NET 2.0 includes a built-in web server called Cassini, which can be used for development purposes. Cassini allows developers to run and test their web applications without the need for a full-fledged web server like IIS. However, when deploying the application for production, IIS is typically used as the web server.

Setting the TabStop property to false for a particular control will prevent it from receiving focus when the user presses the tab key. This means that when the user navigates through the controls using the tab key, this specific control will be skipped, and focus will move to the next control in the tab order.

A hidden form field is the best method to use in this scenario because it allows you to store small amounts of frequently changing information about a page on the client. It is hidden from the user's view and can be easily accessed and manipulated using JavaScript. Unlike cookies, query strings, and URLs, hidden form fields do not have any security concerns.

The correct answer is (1)&(2). This is because ASP+ is both the same as ASP.NET and the next version of ASP.NET. It was an early name used by Microsoft during the development of ASP.NET, indicating that it is a programming language specifically developed for ASP.NET. Therefore, both statements (1) and (2) are correct.
