Objective Toolkit components, like those from any other MFC extension library, can be used in an Active Template Library (ATL) application that has MFC support enabled. However, using Objective Toolkit components in ATL applications easily, effectively, and extensibly requires attention to several issues. These issues are not specific to Objective Toolkit; in fact, they apply to any other MFC extension library as well. To address them, we have provided a set of custom ATL Object Wizards and some sample code that will produce ATL ActiveX controls that wrap Objective Toolkit components right out of the box. In the following sections, we illustrate how to export Objective Toolkit component functionality (through the ATL ActiveX controls you develop) to the users of your controls.
