In Microsoft Windows applications programming, OLE Automation (later renamed to simply Automation [1] [2]) is an inter-process communication mechanism created by Microsoft.It is based on a subset of Component Object Model (COM) that was intended for use by scripting languages – originally Visual Basic – but now is used by several languages on Windows.
Contains the methods needed by the "Object properties" dialog box. For example if the user opens the "Object properties" dialog box and asks for the object to be converted to another type, a method on this interface is called. IOleUndoManager Provides a centralized undo service to both the container itself and to embedded objects.
Object Linking and Embedding (OLE), Microsoft's first object-based framework, was built on DDE and designed specifically for compound documents. It was introduced with Word and Excel in 1991, and was later included with Windows, starting with version 3.1 in 1992. An example of a compound document is a spreadsheet embedded in a Word document. As ...

The OPC specification was based on the OLE, COM, and DCOM technologies developed by Microsoft Corporation for the Microsoft Windows operating system family. The specification defined a standard set of objects, interfaces e.g. IDL and methods for use in process control and manufacturing automation applications to facilitate interoperability.

One difficulty arises when an object persisted in the file changes in size due to an update. If the application that is reading/writing the file expects the objects in the file to remain in a certain order, everything following that object's representation in the file may need to be shifted backward to make room if the object grows, or forward ...
The state pattern is a behavioral software design pattern that allows an object to alter its behavior when its internal state changes. This pattern is close to the concept of finite-state machines . The state pattern can be interpreted as a strategy pattern , which is able to switch a strategy through invocations of methods defined in the ...
