Restrict format

Is there any detailed description on the format of queries you can put
into the Restrict method? Ideally I would like to see a BNF for it.

Only what's available in the Object Browser help, at outlookcode.com and
other Web sites and some examples in various KB articles. I've never seen
any detailed spec covering everything you can do and how to do it.

Very well, I guess it's time to write one. I have a basic bnf together
but I have come across some oddities in my looking into it that maybe
someone can answer.

If I use the restriction "[HomeFaxNumber] = \"\"" it works as expected.

If I use the restriction "[HomeFaxNumber] in \"\"" I get the error
"Unable to parse condition. Error at "in". This suggests to me that "in"
is not a valid keyword, fair enough.

If I use the restriction "[HomeFaxNumber] is \"\"" I get the error
"Unable to parse condition. Error at "". This is odd, surely if "is"
were not a valid keyword, it would appear in the error as it does for
the "in" case?

If I use the restriction "[HomeFaxNumber] like \"\"" I get the error
"Condition is not valid.". Thats a totally different error, maybe a like
comparison can be used. There is certainly a regular expression
comparision in MAPI defined in the same place as all the other comparisons.

Anyway, just some tests, maybe someone out there can shed some light on
these oddities?

Most of the things you are asking are already answered in the Help for
Items.Restrict in the Object Browser. Have you looked at that? For example,
you can only use the Boolean operators And, Or and Not. Like and In are not
supported.

It almost sounds like what you should be doing is creating an
AdvancedSearch. That can use all sorts of terms such as Like.

How about this quirk (hasn't anybody confronted su such a one??):

Create an item with subject e.g.:
"DoubleSingled'

Now try to Filter that out :)
These one ain't gonna work (an I have not found a solution that would):
"[Subject]=" + Chr(34) + """DoubleSingled'" + Chr(34)
"[Subject]='""DoubleSingled''"
etc..

Any ideas, please? :)
 
Dim strFilter

strFilter = "[Subject] = "
strFilter = strFilter & Chr(34) & "DoubleSingled" & Chr(39)
 
Well, thank you, however this is not a working solution (try it yourself).
Note: I need to filter out a special subject case: when ITEM has a double
quote at the beginning, and a single quote in the end; e.g. (from life):
"AOL" money of customers' <-- how would a Restrict string sound for that?

Your sample simply evaluates to the equivalent string we may write with
escape sequences ("<=>"")
Still, even with your example error triggers: Unable to parse condition.
Error at ""DoubleSingled".
 
You're correct, that one didn't work and neither did any of the other
possibilities I tried.

I guess the only solution is to delete all emails from AOL as soon as they
come in <g>
 
Well, that AOL stands only as an example.
The real objective domain is about filtering out all items, which
UserProperty does not match.
And if the value to filter out has such quotes (user can enter anything..:))
, functionality fails at this point..

Thanks for attempts!
 
What I'd probably do is bypass the Outlook restriction/filter methods and
either use a CDO 1.21 MessageFilter object or use Redemption
(www.dimastr.com/redemption) and a MAPITable and filter object. Both of
those could be worked with to set up a filter that could work.
