OLE Automation Wikipedia. In Microsoft Windows applications programming, OLE Automation later renamed to simply Automation12 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. All automation objects are required to implement the IDispatch interface. It provides an infrastructure whereby applications called automation controllers can access and manipulate i. It supersedes Dynamic Data Exchange DDE, an older mechanism for applications to control one another. As with DDE, in OLE Automation the automation controller is the client and the application exporting the automation objects is the server. Contrary to its name, automation objects do not necessarily use Microsoft OLE, although some of Automation objects can be used in OLE environments. The confusion has its roots in Microsofts earlier definition of OLE, which was previously more or less a synonym of COM. Advantages and limitationseditTo ensure interoperability, automation interfaces are limited to use a subset of all COM types. Specifically, automation interfaces must use SAFEARRAY instead of raw COM arrays.

This avoids the need for additional proxystub projects for marshalling out of process. Automation was designed with the ease of scripting in mind, so controllers often provide languages such as Visual Basic for Applications to end users, allowing them to control automation objects via scripts. Automation objects are often written in conventional languages such as C,7 where C attributes can be used to simplify development,8 Languages such as Visual Basic and Borland Delphi also provides a convenient syntax for Automation which hides the complexity of the underlying implementation. Type librarieseditIn order to automate an application, the developer of an automation controller must know the object model that is employed by the target application exporting activation objects. This requires that the developer of the target application publicly document its object model. Sims 3 Update Now Greyed Out'>Sims 3 Update Now Greyed Out. Development of automation controllers without knowledge of the target applications object model is difficult to impossible.

Interfaces are described in Microsoft Interface Definition Language. Type libraries can be viewed using various tools, such as the Microsoft OLECOM Object Viewer oleview.

Type libraries are used to generate Proxy patternstub code for interoperating between COM and other platforms, such as Microsoft. NET and Java. For instance, the. NET Framework SDK includes tools that can generate a proxy. NET DLL to access Automation objects using both early binding with information about interfaces extracted from a type library and late binding via IDispatch, mapped to the. NET Reflection API, with the built in. NET to COM bridge called COM Interop. While Java lacks built in COM support, toolsets like JACOB1. Segue1. 3 can generate proxy source code consisting of two parts, a set of Java classes and a C source for a Java Native Interface DLL from type libraries. These solutions only work on Windows. Another Java based j Interop1. COM components without JNI, using DCOM wire protocol MSRPC and works on non Windows platforms also. Microsoft has publicly documented the object model of all of the applications in Microsoft Office,1. Object models are presented to automation controllers as type libraries, with their interfaces described in ODL.
