Yeah it's easy when you know how! I assume you have the file unzipped somewhere.
OK, copy it to the folder c:\windows\system32 so that it can always be accessed with
the simple command "tray". Give it a try now by opening a command prompt window and
just enter the command "tray" (without the quotes). The little icon appears in the
tray yeah? OK close that. Now try the command "tray calc.exe" (without the quotes).
A little calculator icon appears in the tray. Getting somewhere now! OK close that
and now try "tray calc.exe moricons.dll#37" and you should get a little MS-DOS icon
in the tray - this is icon number 37 (actually 38 because numbering starts at 0)
in the file moricons.dll and you should have the gist of it now. Cheers. Spexx.
