Components in the PT Application

The PT application uses two types of COM components: custom components, which the LitWare developers code for this application, and standard components, which are available in Microsoft® BackOffice® Server products. In addition to components, the application uses modules that contain constants, types, Win32® API declarations, and functions that support the custom components.

Custom COM Objects and Modules, which are designed to be reusable, perform these tasks in the application:

• Retrieve and modify data in a SQL Server database (data access component)
• Create recordsets with the ObjectContext object (MTSEnvironment module)
• Transform data with disparate locale formats (NLS component)
• Support full-text search (Search component)
• Detect, maintain, and extend locale awareness (Lingo component)

Standard Objects and Object Models lists the technologies the PT application uses. These are the objects that Microsoft products include and the object models they expose. Many of these technologies were used in previous scenarios of the BackOffice Developer's Guide (BDG); a table later in this section provides links to relevant topics in these scenarios. The table in this topic provides links to topics within Scenario 3.
