I'm looking for a way to do the following:

When I click or double-click a file or folder in Windows
Explorer, *before* the default action takes place, write
the name and path of the file or folder to
C:\ShellClick.txt

It can be implemented with a dll or exe running in the
background, but I prefer a dll.

A code sample would be nice but a third-party tool that
accomplishes this would be good too. Thanks

Read up on:
SetWindowsHookEx()?

You don't need any DLL.
You can use a WH_MOUSE_LL hook, then WindowFromPoint() and
ListView_HitTest()-ListView_GetItem() with VirtualAllocEx()-
WriteProcessMemory()-ReadProcessMemory()

How would it be handled if not by a dll? A process running
in the background? Know of any code projects that use such
methods? Thanks

Yes, a WH_MOUSE_LL hook is global with an exe without DLL, unlike
WH_MOUSE
I've tested this method on XP. The only difficulty is for the double-
click, replaced by WM_LBUTTONDOWN + test MSLLHOOKSTRUCT.time with
GetDoubleClickTime())
