I just posted a thread, and although this question has to do with the same
project it is an unrelated quesion.

I need the composer of my email form to be able to attach a file. I know
nothing about this aspect of the coding, so I have just shrunk the compose
message main message box down so that it is cut out of the display and you
can only see the attachment box. This can't be the best way to do this...
number one, the message box keeps resizing and is visible (very tacky) even
when I check "do not resize," and two, I would like to know how to do this
via code, or even using an attachment control or field. But I am unfamiliar
with how to set up a text box as an attachment box, and with the whole
"browse" or "insert file" process.
