Component Registration
C-3
Table C-1: Keys
Key Definition
HKEY_CLASSES_ROOT\CLSID
Information about COM classes on the system. Each
component creates a new key under
HKEY_CLASSES_ROOT\CLSID for each of its COM classes.
The key created has a value of the GUID that has been
assigned the class and contains several subkeys with
information about the class.
HKEY_CLASSES_ROOT\Interface
Information about COM interfaces on the system. Each
component creates a new key under
HKEY_CLASSES_ROOT\Interface for each interface it
defines. This key has the value of the GUID assigned to
the interface and contains subkeys with information
about the interface.
HKEY_CLASSES_ROOT\TypeLib
Information about type libraries on the system. Each
component creates a key for its type library with the
value of the GUID assigned to it. Under this key a new
key is created for each version of the type library.
Therefore, new versions of type libraries with the same
name reuse the original GUID but create a new subkey
for the new version.
HKEY_CLASSES_ROOT\<ProgID>,
HKEY_CLASSES_ROOT\<VerIndProgID>
These two keys are created for the component’s
Program ID and Version Independent Program ID.
These keys are constructed from strings of the form
<component-name>.<class-name> and
<component-name>.<class-name><version-number>.
These keys are useful for creating a class instance from
the component and class names instead of the GUIDs.
