I just gave homeMDBBL as an example. Let's assume *any* multi-valued attribute. Also, I too have looked through Google, MSDN, etc. I've seen the 'attribute;Range=#-#' syntax, but have not gotten it to work. It only seems to work on LDAP searches (and I already have the object) or on the GetObjectAttributes interface (can't get this to work either). Once I have the object I don't want to have to do another search (whether LDAP or looking for forward links) just to read the attributes... that's a hack in my book and there has to be a better way.
I'm looking for actual working code... finding docs is one thing, getting it to work is another... :-) Matt > -----Original Message----- > From: Rick Tatem [mailto:[EMAIL PROTECTED]] > Sent: Friday, August 09, 2002 3:43 PM > To: Stum, Matthew J.; [EMAIL PROTECTED] > Subject: RE: Reading multi-value attributes with more than > 1000 values? > > > Hmm...
