Hi,

In order to store my own custom data with an item i used named
properties, and add them via REDEMPTION .HrSetOneProp method ,
is the same possible with folder, and how????

I want create custom property to ost folder e.g. userID property.

By using .HrSetOneProp .. .. .... and passing folder obbject end
up with exception.


Anyone????


TNX in Advance.

Whenever you need a custom property, it must be a named property (see
http://www.dimastr.com/redemption/utils.htm#xmapi and scroll to the Named
Properties section) to make sure it does not conflict with anybody's else
property.
Also note that while folders in PST stores support named properties,
Exchange folders do not.
The standard way to store folder-wide properties is to create a hidden
(associated) message in that folder with a custom message class and use it
to store the data - see RDOFolder.HiddenItems
(http://www.dimastr.com/redemption/rdo/RDOFolder.htm)

Thanks fo replay,

So the add Property option in OutlookSpy's IMAPIFOlder is only for pst
folders???
By the way in order to add property (named) in mail item via
OutlookSpy when i should set a property name???



Thanks.

1. You can set a regular property on a folder when using the Exchange
provider of course, but it will fail for a property in the = 0x80000000
range.
2. Click IMessage button on the OutlookSpy toolbar, then click "Add
Property" button.

2. Click IMessage button on the OutlookSpy toolbar, then click "Add
Property" button.

But where in appeared dialog form i set the name for property??? and
ID ?? how should i get it or calculate it.


Dmitry maybe there is workaround concerning the folder's proeperty??
All i need to save is one property
and every time create RDOFolder and check for hidden item and get the
property from this item it will strike the performance.
I should check for this property every time for every mail that i get.


Thanks in advance.

Select the "This is a named property" radio box, then in the ID edit box
specify either an integer ID (if Kind = MNID_ID) or a srting name (if kind
= MNID_STRING). What that id/name is up to you. Same with the GUID: if you
want to make sure nothing ever collides with your custom tag, pick your own
ubique GUID.
As for perfromance, why can't it be stored in the registry? Or cached in
memory?

Thanks it works, is it possible to add hidden items to folder via
OutlookSpy?? Is it possible to to view for hidden items
in some folder via OutlokSpy (or only to write scipt in the Script
Editor )??


Suppose i have 20 folders or more and for each folder i should add
property e.g. userID,
for example 3 folders may have same userID property other userID in 2
folders and so on,
so in this case i should create some dictionary list that will have
form userID | FolderName
and for each item arrive (a lot items will arrive pereodically) i
should get the property (named) userID from arrived mailItem
check to wich folder (via dictionary) it's belong and then move.
So in the addIn startUp i should iterate over all my folder tree and
build the dictionary.


Any suggestion, to how implement the scenario above???


Thnx,.

OutlookSpy does not let you add new mesages, neither regular nor associated.
There is no specific reason, it is just nobody asked for that feature :-)
To see tehe existing hidden items, click IMAPIFolder button, then go to the
"Associated Contents" tab.
You did not answer *why* exactly you want to store data on the folder level
rather than registry or file system.

The reason to store data on the folder level rather than registry or
file systems is beacause
if some user change his machine or format it's machine all data stored
on registry or file system level are
erased or not available (in case user logged in to other machine and
open Outlook). However when i store
data on folder level, it doesn't matter, cause when user log in to
some machine and configured Outlook to work
against Exchange all data and my data also are syncronized.

What do you think???


Thnask in advance.

Ok, then a hidden item is the way to go.
What kind of data are you storing? Is it really per-folder? If not, you can
store everything as a hidden message in, say, Inbox.
I don't see this as a performance problem as long as you read the data only
wwhen you actually need it and cache it in memory for the lifetime of your
app.
