Now that the web page is complete, you can concentrate on the back-end functionality of the event registration program. This functionality takes over when the user "submits" the form. Submitting the form passes all of the data from the VALUE attributes to the process indicated by the ACTION attribute. In this case, the program is passing the data to an in-process ActiveX component, formerly called an OLE server, that works with oleisapi.dll. You will use Visual Basic 4.0 to create this component. Figure 7-6 (page 270) shows a flowchart of how the event registration information is processed. As you work through the rest of this project, this flowchart will become clearer.
