INFO: Window Handles of Global Objects


The information in this article applies to:

  • Microsoft Windows Software Development Kit (SDK) versions 3.0, 3.1


A handle is a unique, fixed identifier for a global object. Handles exist to allow easy, indirect access to an object that may move in memory.

Handles are unique only among the objects to which they refer. A handle to a window will always be different from all other handles to windows, but it could have the same value as a handle to a brush (or to any other object).

It is safe to hold onto a window handle (or any handle) of a global object. As long as that object exists, its handle will not change.
