Creating Property Pages for ActiveX Controls

See Also

Property pages offer an alternative to the Properties window for viewing ActiveX control properties. You can group several related properties on a page, or use a page to provide a dialog-like interface for a property that's too complex for the Properties window.

In Visual Basic, property pages are displayed in the Property Pages tabbed dialog box, as shown in Figure 10.1.

Each tab in the Property Pages dialog box represents one PropertyPage object. For example, the PropertyPage object that provides the General tab shown in Figure 10.1 was created using the PropertyPage designer shown in Figure 10.2.

In the designer, the PropertyPage object doesn’t display a tab. Nor does it display the OK, Cancel, and Apply buttons. These are provided automatically by the Property Pages dialog, and are not part of any individual PropertyPage object. The Property Pages dialog uses the Caption property of the PropertyPage object as the text for the tab.

In this example, the General page groups two properties, DinoName and Age. The page is laid out to simplify localization; the length of the captions can change without affecting the layout. This is discussed in "Property Page Design Guidelines."

The following topics explain how property pages work, and the different ways you can use them in your ActiveX controls.
