OLE 1.0, released in 1990, was an evolution of the original Dynamic Data Exchange (DDE) concept that Microsoft developed for earlier versions of Windows.While DDE was limited to transferring limited amounts of data between two running applications, OLE was capable of maintaining active links between two documents or even embedding one type of document within another.
For example, a custom in-house application might use DDE to open a Microsoft Excel spreadsheet and fill it with data, by opening a DDE conversation with Excel and sending it DDE commands. This feature has mainly been superseded by the Component Object Model suite of technologies. Microsoft has not used DDE internally since the release of ...
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.
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 to fill in the space left over if the object shrinks.
At the same time, Microsoft stated that OLE 2 would be known simply as "OLE". In early 1996, Microsoft found a new use for OCX – extending their web browser's capability. Microsoft renamed some parts of OLE relating to the Internet as ActiveX, and gradually renamed all OLE technologies to ActiveX, except the compound document technology that ...
OLE DB (Object Linking and Embedding, Database, sometimes written as OLEDB or OLE-DB) is an API designed by Microsoft that allows accessing data from a variety of sources in a uniform manner. The API provides a set of interfaces implemented using the Component Object Model (COM); it is otherwise unrelated to OLE .
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. The COM support in Microsoft Visual C++ allows developers to create a variety of COM objects, OLE Automation servers, and ActiveX controls.
Microsoft Excel contained a hidden Doom-like mini-game called "The Hall of Tortured Souls", a series of rooms featuring the names and faces of the developers. [19] The mini-game generated some controversy when chain emails made spurious claims and conspiracy theories accusing Microsoft—particularly Bill Gates —of hiding Satanic symbolism ...
