Also, is there some reason you are using method="get"
in your <form> tag instead of method="post"
And is this page private to your company? That is, is the page accessible on the internet or is it strictly an inTRAnet page? If it is on the inTERnet, is it password protected?
FWIW, *IF* all my suspicions are correct, I *THINK* you will be able to simply do this on your updatemm_select.asp page to make it change *ALL* of the checked items to maintenance mode:
Conn.open "Provider=sqloledb;Server=server;Initial Catalog=db;UID=user;PWD=pw;"
sql = "UPDATE object SET status = 'maintenance' WHERE objid IN (" & Request("toggle_maint") & ")"
howmany = 0
conn.Execute sql, howmany
Response.Write "Changed " & howmany & " to maintenance mode"
(The actual value you set status
to of course depends on your needs, but that's the general idea.)
If you want, you can just try that code to see if it works.
But if it doesn't work, then I need all that I have asked for from you.
