.NET CONNECTOR

Hi there!

I'm a Visual basic freelancer, at this moment i'm programming an interface with SAPGUI 620,

and in the early times I use the ITOLE.OCX to comunicate with the SAP screens, it worked fine.

Now I need to upgrade to .NET, I'm trying to access the SAP Service Marketplace but since I'm not a client or a partner I don't find a way to enter!

Is there another place where I can find the software and the documentation?

Can someone help me!

PLease...

thanks

Manuel
