I have an application that I would like to intercept and handle the 
messages for inserting an Audio CD. If my application is running I don't 
want to have Windows to launch any other application (i.e. CD Player) 
that may be associated with a CDA file.

I already have a MESSAGE_MAP for the WM_DEVICECHANGE message that seems 
to work, but on my XP Home machine the 'What do you want do?' window 
still pops up. What do I need to do to stop the message going on the 
Windows?

1) Is a VCL_MESSAGE_HANDLER() in the MainForm the best place for this? 
If not, where?
2) Is WM_DEVICECHANGE the only message that I need to trap? What else?
3) How do I tell Windows that I have taken care of the message and that 
it does need to?

I am fairly new to Message Handling and am using BCB5ent SP1 on XP Home. 
Thanks in advance.

Jeff.
