VB Net 2013 Server without app.config

Hi to all!!

Im developing a VB Net 2013 SAP Server with NCO 3. I configured the RFC Server in the VB app with de APP.CONFIG file, but with this technique the connection is harcoded. The problem is that I need to bring to the user the possibility to select values for parameters as GWHOST, NAME, GWSERV and PROGRAM_ID.

Could anyone give me an example?.

Thanks in advance!!
