This interface provides methods for registering and unregistering component category information in the Registry.
This includes both the human-readable names of categories and the categories implemented/required by a given component or class.
When to Implement
There is no need to implement this interface. The Component Category Manager, a system-provided COM object that can be instantiated by using the CoCreateInstancefunction, implements ICatRegister.
When to Use
The owner of a category uses this interface to register or unregister the human-readable names. The owner of a component uses this interface to add or remove categories implemented or required by this component.
Methods
The following table shows the methods for this interface in the order that the compiler calls the methods. Like all COM interfaces, this interface inherits the methods for the IUnknowninterface.
| IUnknown method | Description |
|---|---|
|
Returns pointers to supported interfaces. |
|

|
|
Decrements reference count. |
| ICatRegister method | Description |
|---|---|

Removes one or more implemented category identifiers from a class. |
|
|
Registers the class as requiring one or more component categories. |
|
|
Removes one or more required category identifiers from a class. |
