I am working on a program that reads data from a removable device (USB
Stick) that the user will insert into the computer and then when the
data is removed, will need to remove the media. In the system tray,
there is the icon/tool to "Safely Remove Hardware". How do I do that
programmatically? I am working in C#, so if I can avoid dropping to
the API level, that would be great, but with 10+ years of C/C++
experence, WinAPI level examples work, too!

You need the Setup api's from the DDK/WDK. Get the WDK and look at the
DevCon sample for information on how to do it.

Don,

It looks like the WDK is not a free download, am I correct? If not,
any thoughts on where to go find it? This is the link I found:

http://www.microsoft.com/whdc/devtools/wdk/betawdk.mspx

Actually it is free, you just have to follow the directions. I know the
page says Beta, but it now gives you the release version. Alternatively,
if you can find the last DDK Build 3790.1830 that should work fine also.

I've shown this in user mode in a sample project:
http://www.codeproject.com/system/RemoveDriveByLetter.asp

The page needs an update because of some new findings.

CM_Query_And_Remove_SubTree requires admin previleges, while
CM_Request_Device_Eject does not. Today I've seen that Vista
redetected an USB hard disk immediately after using
CM_Query_And_Remove_SubTree successfully. It did not happen
with CM_Request_Device_Eject.

If you want XP show the "it's save now" balloon, then use
NULL/0 for the veto params. An additional effect is, that
XP doesn't play the removal sound then when the device is
unplugged. Quite strange...
