IInkExtendedProperties interface (msinkaut.h)

Represents a collection of IInkExtendedProperty objects that contain application-defined data.

Inheritance

The IInkExtendedProperties interface inherits from the IUnknown interface. IInkExtendedProperties also has these types of members:

Methods

The IInkExtendedProperties interface has these methods.

IInkExtendedProperties::Add Creates and adds an IInkExtendedProperty object to the IInkExtendedProperties collection.
IInkExtendedProperties::Clear Clears all of the IInkExtendedProperty objects from the IInkExtendedProperties collection.
IInkExtendedProperties::DoesPropertyExist Retrieves a value that indicates whether an IInkExtendedProperty object exists within an IInkExtendedProperties collection.
IInkExtendedProperties::get_Count Gets the number of objects or collections contained in a collection. (IInkExtendedProperties.get_Count)
IInkExtendedProperties::Item Retrieves the IInkExtendedProperty object at the specified index within the IInkExtendedProperties collection.
IInkExtendedProperties::Remove Removes the IInkExtendedProperty object from the IInkExtendedProperties collection.

Remarks

The extended property data is indexed by an application-specific globally unique identifier (GUID).

Note  You cannot store an empty IInkExtendedProperties object. The object must contain data before it can be stored. For example, if you try to add extended properties to a stroke for later use, an exception is thrown if the extended property contains no data.

 

IInkExtendedProperties collections may be added to the IInkStrokeDisp, the InkDrawingAttributes, and the InkDisp objects.

If you define a class that implements this interface, the new class will not interact correctly with the Tablet PC application programming interfaces (APIs).
