There is a public domain thunking .DLL called CALL32.DLL.  I have a
copy available from one of my pages:
http://www.redshift.com/~arcatpet/vb.html

There are also a couple of VB3 program source code samples there that
use the .DLL, one for Win95 taskbar tray usage, and another for
Win95/NT registry reading/writing.  Note that internal documentation
for CALL32.DLL says it will only work on NT, but it was written before
the WOW in Win95 became compliant with the NT version.  No problems
experienced with Win95 - haven't tested with Win32s.
