TextWriterTraceListener class

A class that can write tracing output to any .NET Framework stream object, such as a text file.

tModel

One of the UDDI elements that are used to provide information about a Web service. The tModel element contains the information used to describe compliance with a specification, concept, or a shared design. The element also contains a key, a name, an optional description, and a URL where you can find more information about the XML Web service.

tModelInstanceDetails

One of the UDDI elements that are used to provide information about a Web service. The tModelInstanceDetails element contains zero or more tModelInstanceInfo elements. The tModelInstanceInfo element has an attribute named tModelKey, which identifies a specific tModel. Also included in the tModelInstanceDetails element are a description, a reference to the overview document, and instance parameters.

Trace class

This class from the System.Diagnostics namespace enables you to output messages from your application. These messages can be used to monitor your application’s performance and troubleshoot any errors that might occur when the application is running.

TRACE compiler directive

In order for tracing code to be included in your compiled executables, the TRACE compiler directive must be set to True before compiling your application.

TraceSwitch class

This class enables you to create an object in your application that determines which Debug and Trace messages should be output during application execution, based on the setting for the Level property. This option can be set in source code or in the application configuration file.

TraceSwitch.Level property

A property that determines the priority level enabling you to determine which Debug and Trace messages should be output during application execution. This option can be set in source code or in the application configuration file.

transaction

A set of operations that must successfully complete together. If any one of the steps fails, then the results of all steps must be rolled back, or cancelled.

Transaction.Commit method

This causes the transaction to finish and all pending database changes to be written permanently to the database.

Transaction.Rollback method

This method causes the transaction to finish and all pending database changes to be rolled back.

Transact-SQL

The Microsoft SQL Server database uses its own programming language, called Transact-SQL (or T-SQL for short), to write SQL queries. Transact-SQL is based on the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) standard SQL language published in 1992, and also includes proprietary extensions.

Type Library Exporter utility (tlbexp.exe)

A command-line utility program provided with Visual Studio .NET that exports a COM-compatible type library from a .NET component.

Type Library Importer utility (tlbimp.exe)

A command-line utility program provided with Visual Studio .NET that translates COM type library information into a format that can be read by .NET components.

Uniform Resource Identifier (URI)

Any unique string that is used to identify the publisher of a particular Web service.

Uniform Resource Locator (URL)

A unique Internet address that is used to identify a specific website, web page or Web service.

UniqueConstraint class

This ADO.NET class enables you to specify that a specific DataColumn in the DataTable must have unique data values.

uniquely named root element

A root element whose name is unique within that data file. Every well-formed XML data file must have a uniquely named root element.

unit tests

Tests that determine whether a single set of code, perhaps a single class or a component that contains a few related classes, is correctly performing its tasks.

Universal Description, Discovery, and Integration (UDDI)

A service for locating XML Web services by consulting online registries, such as uddi.microsoft.com, which contain information about available Web services. You can publish information about Web services that your organization wants to make available. You can manually search the UDDI registry sites or use the application programming interface (API) to access a UDDI registry server from your application.

unmanaged code

Applications that run on the Windows/COM platform, such as COM components and Visual Basic 6 applications. Unmanaged code is not executed by the CLR.

Update method

A method of the ADO.NET DataAdapter class. This method processes each row in the DataSet that has a RowState of Added, Deleted, or Modified and runs the appropriate SQL query against the data source for each row.

UpdateCommand

This property of the ADO.NET DataAdapter class is one of the three related properties that hold the SQL statements (or stored procedure names) that will be used when the corresponding insert, update, or delete operations must be performed during an update to the database.

URL-based authorization

Uses <allow> and <deny> elements in the application’s Web.config file to grant and deny access based on the URI the client is requesting and the identity associated with the request.
