To add an ActiveX designer to the development environment, an end user takes these steps:
To find out which ActiveX designers are available, Visual Basic searches the system registry for entries that contain the ActiveX designer component category. Using the class identifiers (CLSIDs) and strings of these entries, it creates the list of ActiveX designers in the Components dialog box. The end user selects ActiveX designers from the box; the selected designers subsequently appear on the submenu displayed when the user clicks the Add ActiveX Designer command on the Project menu.
