Description

This is the first course in a five part series that will provide programmers with the basic skills to build three-tier client/server solutions.

Audience

This course is designed for programmers using Visual Basic 6.0 and are currently building desktop applications and accessing corporate databases. Participants should have completed Designing and Implementing Desktop Applications with Microsoft Visual Basic 6.0 (Courses 72590 - 72594).

Prerequisites

(Currently no course prerequisite information)

Objective

• Identify the features of the client/server architectures, Microsoft Enterprise Development Strategy, phases of the Microsoft Solutions Framework (MSF) process model and the services of the MSF Application model, and the Visual Studio 6 Enterprise Edition development tools.
• Identify the attributes of an interface and conditions of using the interfaces and the functions of the different types of interfaces.
• Create, implement and access an interface.
• Identify the type of binding to be implemented and handle errors in an interface.
• Identify the advantages of COM components.
• Create a project to test a DLL and pass an error back to a client application.
