You might start by looking at the "Copy A Module From One Project To
Another" topic on the web page "Programming The VBA Editor"
(http://www.cpearson.com/excel/vbe.aspx) on Chip Pearson's web site.

Also, search for "VBComponent" on Chip's web site (or any MVP's web site;
see http://www.mvps.org/links.html#Excel).
