Thanks Prabu but I want to get List of Categories in Windows mobile, not Categories of a contact.

Answer 3

You can query the contacts folder's PIMPR_FOLDER_CATEGORIES property to get the list of contact categories. Please read the following thread for more information: http://social.msdn.microsoft.com/Forums/en/windowsmobiledev/thread/cfc5f36b-d197-4953-816d-03f466030caa

This is a very useful. Can you translate this code as Managed Code?

 

Answer 5

You need to use Com Interop to do it in .NET CF. See the following article:

Another way is enumerating all the contacts and get their Contact.Categories property. However the performance may not be as good.
