Set a TermSet value via Word 2010 contentTypeProperties

Hello,

I'm working with Sharepoint 2010 Enterprise and Office 2010 STD, I have an Office Addin which save documents into SPS with several document properties which are sync with sharepoint contenttypeproperties inside the document library.

The problem is with Managed Metadata properties, I want set values into a TermSet property programmatically, but I could'nt realize how....

I already try somethings like this:

lCTprop = xoActive.ContentTypeProperties("Autores2010")

If Not lCTprop Is Nothing Then
   Dim lTerm As String()
   lTerm = Array.CreateInstance(GetType(String), 1)
   lTerm = loProp.Value.ToString.Split("|")
'(loProp is a CustomDocumenProperty which has the value)
   lCTprop.Value = lTerm
End If

any ideas??

thanks a lot,

Mauricio.
