Price: US $1,495, UK £995 + VAT | Duration: 3 days

Programmers and consultants who use Delphi5 or 6 and need to develop / interface with COM applications.

A good working knowledge of Delphi and object oriented programming in Delphi. Our Delphi Fundamentals and Delphi Object Oriented Programming courses provide a solid base for this course.

This advanced course covers Delphi COM Programming in depth. At the end of the course you will able to write and deploy COM and automation clients and server applications, utilize existing COM servers from within your Delphi applications, and make the most of MTS.

COM is also the basis for writing multi-tier applications so you'll get a head start on that as well if you are planning to attend our Multi-tier Development course.

Develop COM based applications, utilize existing COM servers (such as MS-Word and MS-Excel), use Delphi's Interface language feature, write COM interfaces, register COM servers, choose between different types of COM servers, use early and late binding, use the Type library editor, learn how to use Class Factories, and how to create Automation servers
