VB_API problems

Hi everybody,

i wrote an application on ProE/WF4 vbapi that worked well.

I passed to Creo and i got a big surprise: i cannot connect to any session of creo via VB!!!!

I'm using VS2010 and Creo Elements Pro M080 on Windows 7 and XP SP3, i registered all the variables as said in the "manual" but nothing works.

I post my code

(old version WORKING in WF4, NOT WORKING in Creo)

Dim asynconn As New CCpfcAsyncConnection
Dim conn As IpfcAsyncConnection
Dim session As IpfcBaseSession
conn = asynconn.Connect("", "", ".", 5)
session = conn.Session

(directly from PTC manual, still NOT WORKING in CREO)

Dim connection As IpfcAsyncConnection
Dim classAsyncConnection As New CCpfcAsyncConnection
connection = classAsyncConnection.Connect(DBNull.Value, DBNull.Value, DBNull.Value, DBNull.Value)
Dim session As IpfcBaseSession
session = connection.Session

Also the examples in the VB_API folder in Creo do not work.

I need to reach the active session to open a model, selected in an external menu and i need to retrieve the name of the model actually in session.

Does anybody have the same problem? Wayouts?

Tks
