Chapter 25 The ATL and  Objective Grid
Customers often ask whether Objective Grid can be used with ATL. Our answer has been that Objective Grid, like any other MFC library, can be used within an ATL application with MFC support. However, there are minor areas that need to be addressed to enable easy and effective use of Objective Grid inside of ATL applications. None of these issues are really specific to Objective Grid. In fact, you will run into these issues if you write and reuse a simple MFC extension DLL.
