Programming a "Send to" app

Bob Altman

If I put a shortcut to an app in the Send To folder, then I can select one
or more files in Windows Explorer, right-click on the files, select Send
to -> MyApp, and my application will run with the selected file paths
supplied as a command line argument. The problem with this is that the
command line has a limited length. I can only select 15 or so files to send
to my app without truncating the command line.

I've noticed that many of the "built in" items in the Send To folder accept
an (apparently) unlimited number of selected files. What is the mechanism
that they use to get the selected file list, and can I write a .Net app that
does the same thing?

TIA - Bob

They're written as Shell Extensions, usually in C/C++ since you have to deal
with COM.

Take a look at this product, it may be useful:
