I

ID binding

The ability to bind member names to dispatch identifiers (DISPIDs) at compile time (for example, by obtaining the IDs from a type library). This approach eliminates the need for calls to IDispatch::GetIDsOfNames, and results in improved performance over late-bound calls. See also late binding and VTBL binding.

in-place activation

The ability to activate an object from within an OLE control and to associate a verb with that activation (for example, edit, play, change). Sometimes referred to as in-place editing or visual editing.

in-process server

An object application that runs in the same process space as the Automation controller.

interfaces

One or more well-defined base classes providing member functions that, when implemented in an application, provide a specific service. Interfaces may include compiled support functions to simplify their implementation.
