What is OLE?

OLE (Object Linking and Embedding) is Microsoft's component document technology. With OLE, you can dynamically link files and applications together. An object is a combination of data and the application needed to modify that data. You can embed objects in or link them to documents created with a different application.

For instance, an Excel spreadsheet can be embedded within a Microsoft Word document using OLE. Double-clicking the embedded spreadsheet will launch Excel and allow the user to modify the sheet.

Some applications include small applets that are used to create objects. For instance, Microsoft Word includes a drawing tool (MS Draw) and a tool for manipulating characters as art (Text Art) which can be launched only via OLE.
