SAP to VB through IDOCs.Expected pre-requisites in VB ?

Hi All,

I want to transfer data from ABAP to Visual Basic application through IDOCs for updating the database.

Both run on MS-SQL database but on different servers.

What are the pre-requisites should we maintain in Visual Basic system inorder to receive the IDOCs from ABAP for updating database.

Thanks & Regards,

Seshagiri.
