A windows programmer friend asked me to post this:

Microsoft Windows 3.0
---------------------

What I need to be able to do is run a DOS program in a DOS
window that communicates with my Windows program.  Data needs to
flow both ways.  I tried putting data in a file, and having both
programs check for the existence of the file, but my Windows DLL
made the disk thrash horribly while checking for the existence
of 4 files, due I suspect to Windows making all processes update
a directory before reading it.  The Bridge program sends
keystrokes to applications, so I know it can be done.  I tried
using EnumWindows to get the hWnd for the DOS session, then
sending it keystroke messages, but that did nothing (or beeped).
