Release 10.1A: OpenEdge Development:
Programming Interfaces

Support for COM object properties and methods

In Progress, the first step to access a COM object is to obtain its component handle. Once you have the component handle, you can use it to access properties and methods supported by the COM object. To support these property and method references, Progress also provides automatic mappings between COM data types and Progress data types. This allows you to pass COM object property, method, and event parameter values directly as Progress data items without the need for data conversion functions.

For more information on accessing COM object properties and methods, see Chapter 14, " Using COM Objects in the 4GL."
