Not as far as I know - the best you can do is get Word to display its own
dialog box, i.e. Word does not provide you with any facilities in its object
model for modifying the data in a data source.

In any case, Word does not always let you edit a data source. it depends on
the version of Word and the type of data source. For example, sometimes Word
2000 asks you if you want to open MS Query to edit the source. In Word
2002/3, Word will not let you edit a .mdb unless it is in the format it
recognises as an "Office Address List", and so on.

If you happen to know what kind of data source you are dealing with, you
might for example be able to use Word VBA, Word Userforms, and ADO to
present the data and allow it to be edited. Or you might be able to use DDE
to fire up MS Query yourself and let the user edit data in there. But
Microsoft does not provide a single "abstraction" mechanism that lets you do
that kind of thing with no concern for the underlying data format. In my
experience, it's one of those problems that people in the I.T. like to
imagine was solved decades ago, but in reality is still an outstanding and
everyday problem.
