security account

A Windows user login or system account that provides the identity and permissions that the Windows service will run under.

security policies

They are typically set outside the application itself, and can be set by either a custom administration tool provided with the application or a standard tool on the platform, such as .NET’s caspol.exe utility.

SelectCommand property

A property of the ADO.NET DataAdapter class that holds the SQL statement (or stored procedure name) that will be used when retrieving data from the database during a Fill operation. You must specify the query to be used for the SelectCommand manually. Visual Studio .NET can then automatically generate the queries that will be used for the corresponding InsertCommand, UpdateCommand, and DeleteCommand properties.

If a server-activated object is created as a SingleCall object, then it is deactivated as soon as the method call is completed. A server-activated object that is created as a Singleton object will remain in server memory for an indefinite period of time, and a single instance of the object can service requests from many different callers.

Service Control Manager

Simple Object Access Protocol (SOAP) formatter

The .NET Remoting infrastructure uses this formatter to write information in a standardized XML format that can be understood by many applications. This XML format contains the information about the method calls and data that are passed between remote components.

SingleCall object

Your application-specific code can be used to alter the standard SOAP message, or to perform encryption, or message logging, or any other custom processing you require.

SoapDocumentMethod attribute

An attribute that can be applied to an XML Web service method or a method of a proxy class; this attribute indicates that the method expects document-based SOAP messages.

SoapExtension base class

A class in the System.Web.Services.Protocols namespace. SOAP extensions enable you to run custom code each time a SOAP message is processed. To create a SOAP extension, you must create a class that inherits from SoapExtension and override the methods of the base class.

This class provides a means to mark a Web method, so that the specified SOAP extension will be run when the method is invoked.

SoapHeader class

The .NET Framework class that enables you to create custom header fields that can send application-specific information along with the SOAP message.

SoapHeader attribute

An attribute that can be applied to an XML Web service method or a method of a proxy class; this attribute indicates that the method can process a specific SOAP header.

SqlParameter object

The ADO.NET object that holds information about a parameter that is passed to a stored procedure.

SqlTransaction object

The ADO.NET object ensuring that two or more database commands are executed successfully before the changes are committed permanently to the database. If any of the commands fail, all intermediate results are rolled back.

stack walk

A stack walk is a process that examines each of the procedures that are currently pending during application execution. When evaluating permissions for a given piece of code, the CLR examines the permissions granted to the current stack frame, and then starts traveling upward on the call stack, examining the permissions granted at successively higher levels of the call stack, for all method calls currently executing. In most cases, if a permission is not granted at all higher levels of the call stack, the permission is not considered to be in effect, even if it has been granted to the currently executing code.

static discovery

A type of discovery in which the client has prior knowledge of a specific URL for the Web service. It is an alternative to dynamic discovery, in which the client must search all the directories on the web server until it locates an available XML Web service.

stored procedure

Any Structured Query Language (SQL) statement or set of statements that are pre-compiled and saved on the database server along with the database definition. The Microsoft SQL Server database uses its own programming language, called Transact-SQL (or T-SQL for short), to write these queries.

strongly typed DataSet

Also referred to simply as a typed DataSet, this is an object whose definition is provided at design time and expressed in the form of an XML Schema Definition (XSD) document. Visual Studio .NET will also generate a class in your project that expresses the definition in terms of object properties, methods, and events.
