+// Base property page class. Filters typically expose custom properties by
+// implementing special control interfaces, examples are IDirectDrawVideo
+// and IQualProp on renderers. This allows property pages to be built that
+// use the given interface. Applications such as the ActiveMovie OCX query
+// filters for the property pages they support and expose them to the user
+//
+// This class provides all the framework for a property page. A property
+// page is a COM object that supports IPropertyPage. We should be created
+// with a resource ID for the dialog which we will load when required. We
+// should also be given in the constructor a resource ID for a title string
+// we will load from the DLLs STRINGTABLE. The property page titles must be
+// stored in resource files so that they can be easily internationalised
+//
+// We have a number of virtual methods (not PURE) that may be overriden in
+// derived classes to query for interfaces and so on. These functions have
+// simple implementations here that just return NOERROR. Derived classes
+// will almost definately have to override the message handler method called
+// OnReceiveMessage. We have a static dialog procedure that calls the method
+// so that derived classes don't have to fiddle around with the this pointer
