Adding checkboxes from database query

[rworks]

Because Infopath doesn't have a multi-select listbox control, I am
attempting to simulate this functionality using checkboxes in a
scrolling region.

What I would like to do is query for a list of items from a secondary
database, and have the form populate checkboxes into this scrolling
region with the text label and the data source element names that the
checkboxes are bound to taken from this database query.

I would imagine this is possible with some coding, but I am having
difficulty finding any documentation on this. Can someone give me any
information or code samples or ideas that might point me in the right
direction?

Thanks a lot for any help you can give.
