Rules and Custom Code...how can I make the code run before the rules are processed?

[n.repole]

I have a button which has some code behind it and some rules. However,
the code needs to run before the rules are processed. If this isn't
possible, how do I submit via code to both a database and email (the
form needs to be attached).

the XDocument.Submit(); command doesn't seem to be working properly
with my main connection. It does seem to interact with my database and
add a line, however it's only putting one of the many fields I entered
data for into the database.
