Hi,
I'm using Python 2.3 on a Win XP box, and I'm trying to find if there's
a library of some sort that will give you a callback (or something
comparable) when a new disc is inserted into a CD Rom drive. I've done a
little googling and nothing's come up, so I'm not holding my breath. :)
If not, I'm thinking of implementing a thread to periodically read the
volume serial number using GetVolumeInform ation from Mark Hammond's Win
32 extensions, then doing a compare against the last known value. Does
this sound "sane"? Any recommendations would be useful.
Thanks!
Tim

Tim,
Generally, Windows autoinsert notification can be enabled or disabled
for data and audio disks independantly. When autoinsert notification is
enabled on data disks, the Windows operating system automatically does
what CD:\autorun.inf says.
I would imagine that a similar thing occurs on audio cd inserts, except
that it automatically calls the program that is associated with .cda
files.
Certainly there are hooks into the OS that allow one to intercept
filesystem read/write calls (it is what virus scanners do), which could
be tested to see if the read is from a cdrom drive, but I don't know if
Mark Hammond's extensions would be enough, though it is doubtful.
I would suggest polling the serial number every 5 seconds or so, making
sure to deal with the various exception conditions.

ASP.NET 2.0 aspx page with a FormView bound to an ObjectDataSource to view,

Can anyone point me to a sample of how to retain the user entered control

In other words, when inserting a new record, user enters data in the
controls, but the insert fails.
When the page posts back all the controls are empty or at their default
values.

I am struggling with trying to retrieve the value of an autoincrement identity field after a DetailsView Insert operation. The
DetailsView is bound to an SqlDataSource control.
So far as I can tell, nowhere in the arguments for either the Inserted event for the DetailsView or the Inserted event for the
SqlDataSource control is the value stored. Adding a dummy bound column for the identity field to the DetailsView doesn't work,
either.
