GWES Catalog Items and Sysgen Variables (Compact 2013)
3/28/2014
In Windows Embedded Compact, you can implement support for the Graphics, Windowing, and Events Subsystem (GWES) and supporting graphics features that include windows, dialog boxes, controls, menus, bitmaps, cursors, text, and icons. GWES is the interface between the user, the application, and the Windows Embedded Compact OS.
