IMPLEMENTED_CATEGORY

Article
12/01/2015

Add an IMPLEMENTED_CATEGORY macro to your component's category map to specify that it should be registered as implementing the category identified by the catID parameter.

Syntax

      IMPLEMENTED_CATEGORY(
   catID 
)

Parameters

catID
[in] A CATID constant or variable holding the globally unique identifier (GUID) for the implemented category. The address of catID will be taken and added to the map. See the table below for a selection of stock categories.

Remarks

The component categories listed in the map will be registered automatically when the module is registered if the class has an associated OBJECT_ENTRY_AUTO or OBJECT_ENTRY_NON_CREATEABLE_EX_AUTO macro.

Clients can use the category information registered for the class to determine its capabilities and requirements without having to create an instance of it.

For more information about component categories, see What are Component Categories and how do they work? in the Windows SDK.
