 Hopefully it is self-evident that each component of the Windows
architecture was designed to only work with other components of the
Windows archictecture.  That was the entire point of the Windows platform.
 I would think that a VB program can still be written to open a TCP
socket and send and receive data over it.  You could design your own
front-end <-> middle-tier protocol to run over it.  But that is a lot of
work.  More suitable for simply front-end apps.
 Or you could go with Java.  They have definitions and libraries for all
the inter-layer communication you could ever want.  At the end of the day,
it will actually run on anything too.
 Or you could go completely web-based.  The browser is the front-end and
uses HTTP to the middle tier.
