A-B

AcceptChanges method

A method of the ADO.NET DataSet, DataTable, and DataRow classes. This method makes any user changes permanent and resets all values of the object to match the current values. After AcceptChanges is a called, the original database values are lost and rows are marked with a RowState property value of Unchanged.

ACID properties

A term used to describe important features of how transactions work. ACID stands for Atomicity, Consistency, Isolation, and Durability.

ADO.NET Toolbox components

Visual Studio .NET enables you to add commonly used objects, such as ADO.NET Connection, Command, DataAdapter, DataSet, and DataView objects to your project by selecting them from the Toolbox. The components can then be configured by using the Properties window or, in some cases, a wizard. The code that is needed to support these components is automatically generated and added to your project by Visual Studio .NET.

application domain

A Common Language Runtime feature that provides a new way of isolating managed code applications that are running on the same computer. Instead of requiring each application to run in a separate memory process on the computer, as in COM applications, you can run several application domains in a single process.

Application Proxy Remote Server Name

The name of the remote server that your components will be installed on; this is set when creating a Windows installer file (.msi).

assembly attributes

Attribute settings that are added to your application at the assembly level. Attributes can be set to control how your application works when running under Windows Component Services.

Assert method

This method of the Debug and Trace classes enables you to provide an expression that you expect to evaluate to True while your application is running as expected. When the test expression evaluates to False, the Assert method causes an error dialog box to be displayed and messages to be written to the Output window.

asymmetric cryptography

A type of cryptography that uses different keys to encrypt and decrypt data. Encryption algorithms add better protection by using asymmetric cryptography.

asynchronous callback function

A method that is specified to run when an asynchronous call to a remote object or web service has completed.

attribute

An XML element can contain one or more attributes, which carry additional data. Attributes are in the form of a name/value pair, and the attribute value must be enclosed in quotes.

authentication

The process of demonstrating who you are, to the system. This is most commonly accomplished by providing a username and password.

authorization

The process of verifying that a process has the required permissions to perform specified system actions. It is closely connected with authentication in that the identity of the user running the process often determines what the process is authorized to do. In .NET, authorization is provided by a combination of the Common Language Runtime’s code access security and role-based security mechanisms.

AutoComplete attribute

When a method’s AutoComplete attribute is set to True, the method’s “vote” to commit or roll back the transaction will be set to Commit if the method completes successfully.

AutoLog property

A property of the .NET Framework ServiceBase class (the class that all Windows service applications inherit from). When this property is True, entries will be written to the Windows Application event log when the service is started, stopped, paused, or continued.

binary formatter

Creates a binary data stream containing the method calls and data that are passed between remote components. This binary data stream can be read only by .NET-compatible applications.

bindingTemplate element

One of the UDDI elements that are used to provide information about a Web service. The bindingTemplate element is used to describe the technical specifications that are required to bind to a particular XML Web service. The binding information is either an access point or a hosting redirector.

BooleanSwitch class

This class enables you to create an object in your application that indicates whether Debug and Trace messages should be output during application execution. This option can be set in source code or in the application configuration file.

BooleanSwitch.Enabled property

The Enabled property of the BooleanSwitch class determines whether Debug and Trace messages should be output during application execution. This option can be set in source code or in the application configuration file.

breakpoints

The Visual Studio .NET code editor enables you to set breakpoints that specify at which line of code theexecution of your application should break (or be suspended) so that you can examine variable values and other application information. You can then continue executing code by stepping line by line. In Visual Studio .NET, a breakpoint can be defined to hit on only a specified expression value or hit count, and they can be saved with the solution.

businessEntity

One of the UDDI elements that are used to provide information about a Web service. The businessEntity element describes the business that is the responsible party for registering the XML Web service in the UDDI. This element contains details about the business, such as its name and contact information.

businessService

One of the UDDI elements that are used to provide information about a Web service. The businessService element describes the XML Web service that the business entity is exposing. This element names the service as well as associates it with a business entity and binding information. You can also assign categories to the Web service, such as industry or product.
