Adding Categories Programmatically

[Odd Spot]

I have an add-in that listens for a SelectionChange event on any active
explorer. I then add a category to each MailItem in the selection by
using the following code:

String newCat = "New Category";
Selection s = application.ActiveExplorer().Selection;
foreach( MailItem selectedItem in s ){
String cats = selectedItem.Categories;
if (cats == null || cats.Length == 0)
selectedItem.Categories = newCat;
else if (cats.IndexOf(node.RelativePath) == -1)
selectedItem.Categories += "," + newCat;
}

Once this is done the Categories property shows the new category, but,
on all but the first mail item in the selection, the categories list
accessed from Outlook does not display the new category and a search
folder that is searching for the new category will not find any of the
emails but the first. Furthermore, when Outlook is restarted only the
first email will continue to have the category, even in the Category
property.

Any ideas about what is going on here? Is there a better way to add or
remove a property then via the Categories property?

I don't see any statement to save the item. Also, you can't assume that
every item in the selection is a MailItem.

Sue,

Thanks, Saving the MailItem does the trick.

Also, do you know of any way to create a search folder that retrieves
every message from a specific folder? I know there is an "InFolder"
property, but this property does not contain the full folder path, so
if I have two folders with the same name than the search folder will
retrieve everything from both folders.


Thanks,
Jared

I imagine it can be done, but why? A search folder that shows all the items
in a folder is identical to the original folder.

Sue,

Also you mentioned the fact that you can't guarantee that every item in
a Selection object is a MailItem. What is the proper way to check for
this. The getType() method returns an ambiguous com object reference,

Use the Class property.

I am trying to create Search Folders that aggregate all of the messages
from a given folder and all of its child folders, but am currently
getting extra messages because of this issue.

That makes more sense. You'd need to use AdvancedSearch to create the
search. Scope should be the path to the top-level folder you want to search,
then use no FIlter and SearchSubFolders set to True. Once the search
completes, use Search.Save to create the search folder.

Sue,

That makes sense, but unfortunately there are certain situations where
I need to look for a given category as well, and therefore can not
limit the scope to just the top-level folder, as there may be messages
with this category elsewhere.

Sorry to make it more complicated. I should have fully explained the
situation from the get-go.

Thanks for all the help already.

Jared

Then why did you say this earlier:


Have you tried this syntax, as documented at
http://msdn.microsoft.com/library/en-us/vbaol10/html/olmthAdvancedSearch.asp:

Const strScope As String = "'Inbox', 'Calendar', 'Tasks'"

You'd use a path string for each folder, I think.

Sue,

Well I need to create an AdvancedSearch that performs both tasks:

1) Find all mail items from a given folder and its sub-folders.
2) Find any mail items that have a given category regardless of what
folder they are in.

So the scope parameter is not going to help because a message with the
correct category could exist in any folder.

Let me know if I am misunderstanding your suggestion.

Jared

Then maybe start the search at the root of the information store?
