@Wims:
why would this not be the right forum? he's asking for a script..
@sparta:
You can indeed write a DLL for this. See the
Shell_NotifyIcon WINAPI function if you know enough about DLLs to take this on. On a sidenote, if you can include a .dll file in your script you can surely include a .exe file.. Similarly, if you can't include a "program" in your script, you probably can't include a dll file either, I'd imagine.
