Interface Key

  • Article

Registers new interfaces by associating an interface name with an interface ID (IID). There must be one IID subkey for each new interface.

Registry Key

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Interface\{IID}

Registry value Description
BaseInterface Identifies the interface from which the current interface is derived.
NumMethods Contains the number of methods in the associated interface, including methods from derived interfaces.
ProxyStubClsid Maps an IID to a CLSID in 16-bit proxy DLLs.
ProxyStubClsid32 Maps an IID to a CLSID in 32-bit proxy DLLs.

 

Remarks

The HKEY_LOCAL_MACHINE\SOFTWARE\Classes key corresponds to the HKEY_CLASSES_ROOT key, which was retained for compatibility with earlier versions of COM.
