I'm not sure why you wouldn't receive any input, I set up this simple test of my answer to your post with a batch file I wrote, if you don't use a flag, you get the standard "hello", and if you do use a flag you get an echo of the flag.
This is on a Win7 machine -
Open your message box, and run your batch file the same way, with the flag your shooting for, then put a screen shot of it if your still not seeing the result you expect so we can see what is happening.
*Edit - I had forgotten about what Thunder pointed out -
in your tron.bat file :
:: Requirements: Run from the current users desktop. Run as Administrator.
I'm not sure that Win runs it as an admin just because your running the exe calling it as an admin. It has been too long since I used Windows for me to remember either, but I'm pretty sure you'd have to call the bat with admin credentials, not just from the sign in.
