Where are CD-ROM autorun flags?

[Clay Clear]

Does anybody know where Win98 SE stores the info on whether to
autorun data and audio CD's? I am a licensed user of StepUp98,
and can use its CD enable/disable facilities, BUT, I'd rather
write my own program that does the same thing, so I don't have
to install the whole StepUp software just to use that feature.

I've done a search in my Registry for "autorun", and the only
key that I found that held potential, the value data in it
didn't change when I used StepUp to change the data autorun's
status. So, Windows must keep the info elsewhere.

Any ideas?

Thanks in advance!

OK, I found *ONE* flag, and I think it's the only one for
autorunning CD's that Win98 SE uses. Apparently, StepUp has a
"hook" into the autorunning process, so it can selectively
autorun audio and/or data CD's. I'm going to do further
experimenting with the flag I found to see if I can write my
own program to toggle the autorun status on/off. Unfortunately,
I don't know enough about 32-bit Windows programming to be able
to write it so it can selectively autorun audio and/or data CD's.

I'll look in my Sources. I've written such a Program some Time ago.

Hint: You can analyze the modifications, "StepUp" does with RegMon from sysinternals.com

Many thanks, Sven! I downloaded regmon per your suggestion,
ran it, and IMMEDIATELY found out where the Registry key was that
controls the autorunning of audio CD's! I have determined,
through empirical testing, that the flag I found for data CD's
is the correct one.

So, there's now no need for you to look through your old
source codes for the program you wrote. Thanks, anyway, though.


Now, that brings up some questions that I haven't been able to
figure out on my own. First: how do I change the (Default)
value in a Registry key using RegSetValueEx()? I've tried a
number of different settings for the value name, to no avail.
Also, do I use REG_SZ for the data type for that value? Also,
how do I read the value data for that value using
RegQueryValueEx()?

If you can answer these questions, I shall immediately begin
writing my own CD autorunning toggling program.

Thanks, again, Sven!

Sven -

Disregard my previous message! This time,a s far as setting
the (Default) values, I turned to MSDN Library - January 2000
for info on RegSetValueEx...that was where I learned that, to
read or set the (Default) value in a key in the Registry, you
use a null string for the value name. I have tested that, and
it is indeed true.

So, I am now going to write my CD autorunning toggling program!

Clay, JFYI, your URL in your sig line returns an Error 404 (not found).

Lance -

Thanks, but that's because my site is currently offline. I have
been making MAJOR recoding to the programs that I release to
the General Public. Therefore, I have deleted all the files
on the site, and will start over. However, since it returns
an Error 404, that means it can't find the INDEX.HTML, so, I
must've deleted that, too.

I'll post my backup copy of the INDEX to the site, and
annotate it to the effect that the site is currently under
construction and will be fully operational on such-and-such
a date.

Thanks for the heads up, Lance!
