I am having a hard time finding questions I previously posted...is there a
way to search for questions posted by a particular user?
Also, is there a way to sort the search results based on the most recent to
oldest?
Microsoft's webpage (which you appear to be using) is just one of many tools
to get to the messages in this forum. It's far from the best.
The messages are actually stored "Newsgroups", a pre-WorldWideWeb technology
that's still very useful. There is no central storage location; instead the
messages are copied to thousands of news servers all over the world. If you
post from the Microsoft webpage they'll start up on a server named
msnews.microsoft.com, but they'll be copied in seconds (or days) to many other
servers.
You can use Windows Mail, or Outlook Express, or Agent, or any of many other
"newsreader" programs to connect to the message store directly, bypassing the
buggy and incomplete Microsoft webpage altogether. Just point your newsreader
to msnews.microsoft.com as the news server.
You can also use
http://groups.google.com/advanced_search?q=& to search for
messages in this group (it's named microsoft.public.access, though Microsoft
doesn't make that fact obvious), or other related groups such as
microsoft.public.access.gettingstarted, microsoft.public.access.tablesdbdesign
or microsoft.public.access.queries (there are lots more, you can find them
using Google Groups). And you can sort the messages you find by date, by
relevance, by subject, etc.
