Hi Brian,
Yes, you can do this. If the text is within a named HTML element (if the
element has id="foo" or name="foo" in the tag), it is easier to get via the
GetElementByID or GetElementByName, which are methods of the Document or
Body object, I think. If not, you'll have to search the whole body for it
using Document.Body.InnerText or InnerHTML to get the text or source of the
document body.
So the process would go: 1) navigate to the signon page, 2) read the value
you need using one of the methods above, 3) post the form data to the signon
processing page (the action attribute of the form element), then hopefully
you'll be logged in.
If you continue to have problems, please post the URL, and I'd be happy to
help you further.
