Visual Basic Concepts

Creating an ActiveX Document

See Also

The series of step-by-step procedures in this chapter builds a simple combination of two ActiveX documents and two forms. The project is not intended to be a functioning application, but building it will quickly demonstrate object lifetime, global objects, and a set of components working together in Internet Explorer. You will also see how to debug an ActiveX document using Visual Basic's debugging tools.

All of the subjects introduced in these procedures are covered in greater depth in later chapters. References to in-depth material will be found in each procedure. In addition, "Building ActiveX Documents" shows how you can use the ActiveX Document Wizard to make building an ActiveX document even easier.

Note   To complete the step-by-step procedures in this chapter, you must have Microsoft Internet Explorer and access to the Internet or an intranet. You can install Internet Explorer from the Tools directory of your Visual Basic CD-ROM.

The procedures for creating the ActXDoc project build on each other, so the sequence in which you perform the procedures is important.
