LeadTools development in PB classic

Hi,

I want to use LeadTools (Version 19.0) in Powerbuilder Classic.

Older version of LeadTools were giving ActivX controls which were easily usable in PowerBuilder but now LeadTools provides only .Net and C++ .dll class objects.

We want to use these Dll to and its components to generate GUI view of LeadTools in Powerbuilder.

.Net directly give facility to add reference of .dll files and use all the components of the the dll.

Can anyone help me on how to use these .dll files in  Powerbuilder Classic?
