Creating U3 application Icons

I read the articles on here and they were very useful, I created my own basic XML manifest and also used "Shortcut Creator 4U3".

The only problem I can't resolve or in fact I can't work out the required syntax in the XML so I can pass parameters to the application when I launch it, for example this does not work:

++++++
<?xml version="1.0"?>

Xming.ico
Xming

+++++

I'm trying to execute the program Xming and at the same time pass the parameters to the application rather like a DOX batch shortcut:

:0 -ac -multiwindow -fp %U3_DEVICE_PATH%\Program Files\Xming\fonts\75dpi,%U3_DEVICE_PATH%\Program Files\Xming\fonts\misc,%U3_DEVICE_PATH%\Program Files\Xming\fonts\TTF,%U3_DEVICE_PATH%\Program Files\Xming\fonts\Type1,%U3_DEVICE_PATH%\Program Files\Xming\fonts\urw -clipboard

Any Wisdom out there and thanxs !!!!
