Q. How do I get the <PARAM> tag to work with an ATL control? A. You need to support the IPropertyBag interface for the HTML <PARAM> tag to work with your ATL control. An implementation of this interface is supplied in the IPropertyBagImpl class that comes with ATL 2.1. The CIRC sample demonstrates how to support IPersistPropertyBag and add your properties to the property map.
