i have a question about rename table through ADOX with C++

i have find some code on web :
Dim cn As ADODB.Connection
Dim t As Table

Set cn = New ADODB.Connection
cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;data Source=C:\biblio.mdb"
Dim cat As ADOX.Catalog
Set cat = New ADOX.Catalog
Set cat.ActiveConnection = cn
cat.Tables("Authors").Name = "Authors2"


'Iterate through the tables collection
For Each t In cat.Tables
If t.Name = "Authors2" Then
Debug.Print t.DateModified
End If
Next


cn.Close
Set cn = Nothing


There are some problem when i try to change it into VC++ .net format
Set cn = New ADODB.Connection < ---- i cannot new it by using cn = new
ADODB::Connection
cat.Tables("Authors").Name = "Authors2" < -------- Tables doesnt take

any argument

Moreover
Dim cat As ADOX.Catalog < ----Interop::ADOX::Catalog *cat it is work


Set cat = New ADOX.Catalog <------ cat = new Interop::ADOX::Catalog it
dont work, it said error C3153: 'Interop::ADOX::Catalog': you cannot
create an instance of an interface


Is anyone try it before , please give me some guidance on changing the
above code into VC++ .net . Thanks
