Answer 1

Form VB.NET appliaction you have two ways to connect to SAP system and execute BAPI. Either through webservices or by using NCo. Choice depends upon you appliaction requirement.
For starting with NCo go through
http://help.sap.com/saphelp_nw04s/helpdata/en/a9/4a57c1bac80e4e977d8cd9b3ecab89/frameset.htm
OR
THIS IS ANOTHER WAY TO LOGIN TO SAP THROUGH VB TRY THIS.
Logon with the SAPLogon control, Use an RFC call from the SAP Function
Control, and get the results with the SAP Table Factory Control. . .
You must have SAPGui's FULL install on your machine for this to work (Or at
least SAPLogon and the RFC toolkit)
This VBScript example might help, it calls RFC_READ_TABLE in sap, and emails
the results back to a user from a selected query (In this case uses that are
locked out.
This should show you how this could work in practice.
