How do I add user-defined field to folder in C#?

[Mikael]

Hi!


I am coding a solution that has a function to sync it's database with
Outlook. I use a User-Defined Field to keep track of "my" items and it works
great. BUT - I can not find a way to add the user-defined field to the
folder programmatically. If an app is to be distributet widely I can't ask
my users to do this by hand.

I have noticed that som apps (like Skype) has added user-defined fields
automatically, so there has to be a way - do you know or could you point me
in the right direction? I'm coding in C# and Visual Studio 2005.

That's one of the arguments when you create a UDF:

Outlook.UserProperty myUDF =
(Outlook.UserProperty)item.UserProperties.Add("myProp",
OlUserPropertyType.olText, true, missing);

Where "missing" is a missing value for display format.

When you add that user property to an item in the folder that way it creates
it as a UDF in the folder.

Thanx.

I did not get that to work earlier for some reason - maybe because I used
false insted of Missing.Value...
