COM Fundamentals I

( WT-1190-180 )


     Course DescriptionBack To Top

Course Offered in Partnership With DigitalThink

COM Fundamentals I provides programmers with an introduction to COM's architecture, components, and interfaces. It also provides an introduction to how to create COM software objects in Visual C++. Students will explore the COM architecture, components, and interfaces through the course project, a basic in-process COM server and client.

This course requires Microsoft Visual C++ 5.0 or 6.0. It also requires a computer running Windows, Macintosh, or UNIX. To complete the exercises, however, you must have access to a computer running Windows 95/98/NT.

eMentoring Services are included with this course.
