Interface Registry Key (Compact 2013)
3/26/2014
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. |
