+
+OLE 1.0 released in 1990, OLE 2.0 released in 1993, in 1994 OLE custom controls (OCXs) were
+introduced.
+
+OLE objects and containers are implemented on top of the Component Object Model.
+
+Next release after 2.0 introdused in 1996 and named as ActiveX.

+** ATL.

+The Active Template Library (ATL) is a set of template-based C++ classes developed by Microsoft,
+intended to simplify the programming of Component Object Model (COM) objects.

+
+** MFC.
+
+MFC (Microsoft Foundation Classes) is a library that wraps portions of the Windows API in C++
+classes, including functionality that enables them to use a default application framework. Classes
+are defined for many of the handle-managed Windows objects and also for predefined windows and
+common controls.
+
+A lightweight alternative to MFC is the Windows Template Library (WTL).

+
+** WTL.
+
+WTL (Windows Template Library) is a free software, object-oriented C++ template library for Win32
+development.
+
+WTL provides support for implementing various user interface elements, to MDI, standard and common
+controls, common dialogs, property sheets and pages, GDI objects, and other common UI elements, such
+as scrollable windows, splitter windows, toolbars and command bars.
+
+Most of the WTL API is a mirror of the standard Win32 calls.
