Interface Key
This key registers new interfaces by associating an interface name with an interface ID (IID). The named values are stored under the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Interface
If your application adds a new interface, the Interface key must be completed for OLE 2 to register the new interface. There must be one IID subkey for each new interface.
Note You must use ProxyStubCLSID32 because the IID-to-CLSID mapping may be different for 16-and 32-bit interfaces. The IID-to-CLSID depends on the way the interface proxies are packaged into a set of proxy DLLs.
The following table shows the named values for the HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Interface key.
| Value : type | Description |
|---|---|
| \<IID> = name of interface | Provides the textual name for a given interface. For example: \{00000112-0000-0000-C000-0000000000-46} = IOleObject If your application adds a new interface, the interface key must be completed for OLE 2 to register the new interface. There must be one entry for each new interface. |
| \BaseInterface = <name of interface> | Identifies the interface from which the current interface is derived. |
| \NumMethods = <number of methods> | Contains the number of interfaces in the associated interface. |
| \ProxyStubClsid32 = <CLSID> | Maps an IID to a CLSID in 32-bit proxy DLLs.
This is a required entry because the IID-to-CLSID mapping may be different for 16- and 32-bit interfaces. The IID-to-CLSID mapping depends on the way the interface proxies are packaged into a set of proxy DLLs. If you add interfaces, you must use this entry to register them (32-bit systems) so that OLE can find the appropriate remoting code to establish interprocess communication. |
