Object Linking and Embedding
& Embedding (OLE) is a proprietary technology developed by Microsoft that allows embedding and linking to documents and other objects. For developers, it brought OLE Control Extension (OCX), a way to develop and use custom user interface elements.
Commands that an object might typically wish to implement may include things like "delete", "cut", "copy", "paste", "undo", "find", "print", "save", "zoom", and so on. When the context-sensitive help function is turned on, typically the mouse-pointer changes to an arrow with a question mark to indicate that clicking a user interface element will result in opening a help window. In 1993 some Microsoft competitors established a consortium called the Component Integration Laboratories ("CIL") to develop OpenDoc as an open standard for cross-platform linking and embedding.
