If the container for your Active Document is an application such as Office Binder
that isn't Internet-aware, then you must use the features of the container's object
model that enable you to open documents. You will need to use the container application's
documentation to discover how to do this, or you might be able to get this information using
the Object Browser.
Office Binder, for instance, has an object model whose top element is known
as "Binder." The Binder object contains a collection of sections, and each Section object
corresponds to an open document. To add a new document, you must call the Add method of the
Sections collection. Assuming you have a document path and name in the variable
strDocName, you could write code like this to open that document when Binder is the
UserDocument.Parent.Parent.Sections.Add , strDocName
Note that there's a blank first argument to the Add method. This corresponds
to an index, which you allow to assume a default value.
