Is there a way to add code to sharepoint (WSS) pages ?
I am not looking to create a webpart. I just want to add some lines of
server-code to EditForm.aspx or DispForm.aspx.
I was told that there is a webpart or extension that allows you to do just
that. I am ok with installing such a webpart as long as the code I am adding
to the different pages does not need to be wrapped itself in a webpart

Hope this is not too confusing ....
One of the things I would like to do as well is to use includes. Right now
if I include XML code the page breaks, however if I inline the code it works
fine. I wanted to move all the XML-code to its own file to be included at
various places - much easier to maintain, however sharepoint bulks at the
include (no permission)...

Much thanks for any help!
