CFOBJECT Type="COM"
CFOBJECT allows you to create and use COM (Component Object Model) objects. Any
automation server object type that is currently registered on a machine can be
invoked. You can use a utility like Microsoft’s OLEView to browse COM objects.
OLEView, as well as information about COM and DCOM, can be found at Microsoft’s
OLE Development web site http://www.microsoft.com/oledev/.
To use CFOBJECT, you need to know the program ID or filename of the object, the
methods and properties available through the IDispatch interface, and the arguments
and return types of the object’s methods. The OLEView utility can give you this
information for most COM objects.
