Embedded windows, whose client areas are displayed in .NET forms, also appear on the window chain, and could be represented by both WindowX and WindowY in Figure 1. At the same time, both FormA and FormB could represent forms with associated embedded windows. While the client areas of embedded windows and associated forms are linked, you must manage each type of object using its native mechanisms. The behavior and state of embedded windows changes compared to non-embedded windows, but their status as window widgets in an ABL session is the same.
