Who Need Use COM and OLE Diagram?

• Software developers: Diagram publicly-exposed COM and OLE interfaces in object-oriented programming.

• Software designers: Show the relationship between COM objects and the interfaces they reference.

• Software program managers: Model the communication flow between OLE servers and containers.

COM and OLE Symbols

The COM and OLE template includes shapes for all the icons and symbols you can use to create COM and OLE diagrams. It also includes a variety of connector shapes you can use to connect COM objects, object models, and other shapes.

COM and OLE

COM (Component Object Model) is a binary standard you can use to construct software applications from components written in different languages.

COM specifications regulate how the components are structured and how they operate with other components. The specifications govern:

• The structure of component interfaces.
• How components communicate, including across process and network boundaries.
• Shared memory management.
• The dynamic loading of components.
• Error and state reporting.
• How components and interfaces are uniquely identified.

OLE (Object Linking and Embedding) is a subset of COM functionality.

Create a COM Diagram

1. On the File menu, point to New, point to Software, and then click Com and OLE.
2. Drag a COM object shape onto the drawing page from COM and OLE.
3. To change the style of the COM object shape, right-click the shape and choose COM Style.
4. Name the COM object by selecting it, and then typing.
5. Add interfaces to the COM object by dragging the control handle in the center of the shape.
6. Name the interface by subselecting it and then typing.
7. Note All COM objects are created with one interface, IUnknown, by default.
