| COM and Active-X for Visual Basic Developers |
| Duration: 4 days |
|
|
|
- Application developers
- Programmers
- System designers
- Software architects
|
|
Experience with
Visual Basic is required. |
|
|
| Description |
| This
course covers the essential and most important aspects of implementing
reusable software components using Microsoft COM objects. COM
is the Microsoft strategy for software assembly, and the foundation
for technologies known as Active-X and DCOM. The course teaches
COM from the ground and up. In the course we will implement the
components using the latest version of Visual Basic. We will also
show how the COM components can be integrated into applications
and the WEB. The course uses revolutionary teaching techniques
that enhance the students understanding for component models and
basic object-oriented design. |
