Windowless Rich Edit Controls

This section contains information about the programming elements used with windowless rich edit controls. The Component Object Model (COM) defines a set of interfaces to support windowless objects. Windowless objects can enter the in-place active state without having their own window, but rather use the window of their container. Consequently, a windowless object uses fewer system resources and gives better performance through faster activation and deactivation. In addition, windowless objects can be nonrectangular and transparent.
