Sol 7 code

in my VB6 Solomon 6.5 programs I did:
Dim project As String
project = sivMyApp.Controls("cProject")


After the upgrade tool runs it changes that to:
Dim project As String
project = 
SWIMAPIVbaObjectModel_definst.sivMyApp.Controls("cProject").ToString()




What else do I need to do to use sivMyApp  or should I be using other 
method?
Imports Microsoft.Dynamics.SL
dim sivMyapp as new ??? = current form?


TIA
