Hi --

Anyone have any experience with WriteConsoleInput in a console app on Win9x? I'm
finding that while it seems to be executing flawlessly -- reports correct number of
records written, no error codes -- the results are always clamped to 15 characters.
The remainder are just lost. Same code behaves entirely as expected on any NT
platform.

Known issue? Any workarounds?

Thanks... Karl

I can't reproduce your problem. Do you have any DOS drivers loaded
which might limit the size of the input buffer (such as ANSI.SYS)?

Interesting. Yeah, I was running ANSI.SYS as well as an old utility called VISITYPE
that supposedly expanded the buffer. But I noted the failure before loading either,
and actually hoped those would help. Removing them didn't remedy the situation. I
am running in a VPC07 VM, though. Don't have access to an actual 9x box to test on.

What I'm attempting to do is stuff the keyboard buffer right before exiting the
application, rather than feeding an active console session. Suppose that could be a
factor?

Thanks... Karl
