creating extended properties in an sql database

I've been following the example code for creating extended properties given
in the MSDN artical:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/createdb/cm_8_des_08_7qb7.asp

I am able to create the property, however, I am unable to utilize it.
Whenever I run an SQL statement in Enterprise Manager to list the properties,
it shows the property name and shows the data type as <Binary> and does not
allow me to edit it. How can I change this so that I can store useful
information in the extended property?
