2.8.3 For OLE controls

The DUIM-OLE-Control and OLE-Control-Framework libraries are both high-level frameworks for developing OLE controls. The choice of library depends on whether you are using DUIM or the low-level Win32 FFI libraries (Win32-user and Win32-GDI; see the chapter on Win32 API libraries in the Interoperability I reference volume) to develop your control's user interface.

The OLE and OLE-Controls libraries, both FFI interfaces to the C-based Win32 OLE (compound documents) and OLEPRO32 (OLE controls) libraries, are low-level but complete, and may be a useful supplements to the higher-level libraries.

The DUIM-OLE-Control library exports the module DUIM-OLE-Control, and the OLE-Control-Framework library exports the module OLE-Control-Framework.

The OLE library exports the module OLE, and the OLE-Controls library exports the module OLE-Controls.
