The concept of a project group enables you to work with multiple projects open
at the same time. In versions of VB before versions 5 and 6, you could only accomplish
this by using multiple instances of Visual Basic, making it difficult to work
with the projects as one complete system. Working with multiple design-time projects
at once was actually impossible in versions 3 and below, because these versions
did not enable you to have more than one instance of VB running at a time!
As many of the systems built with Visual Basic 6 are component based, using
multiple ActiveX projects, it is very important to be able to work with all the
components in one development environment. This chapter covers the following topics:
- What exactly project groups are, and how you can use them.
- How to use project groups in component-based development.
- How to debug multiple-project applications using project groups.
NOTE - Other ActiveX Control Debugging Techniques Not
Discussed Here: Because this chapter deals with project groups, it does
not discuss other techniques available in VB6 for debugging ActiveX controls.
