Javascript in Vb.net

[VisualBasic2008]

Hey everybody,

I am trying to add some Javascript code into a VB.net webbrowser. I am not sure how I would do this. The code is for a Firefox Grease monkey script.

Here it is:

// ==UserScript==

inputs = document.getElementsByTagName("input");
var checkedyes = 0;
var radios=0;
var firstradio=0;
var foundradio=false;
var i=0;
for(i=0;i<inputs.length;i++)
{
if(inputs[i].type=="radio")
{
if(!foundradio)
{
firstradio = i;
foundradio = true;
}
radios++;
if(inputs[i].value.toLowerCase()=="no")
{
inputs[i].checked = true;
inputs[i].click();
document.body.focus();
}
else
{
inputs[i].checked=true;
}
}

}
if (radios>2)
{
inputs[firstradio+2].checked=true;
}

next = document.getElementById("nextOffer");
if (next == null)
{
next = document.getElementById("pass");
}
if (next == null)
{
next = document.getElementById("bt_cancel");
}
if(next == null)
{
for(i=0;i<inputs.length;i++)
{
if((inputs[i].type=="submit") && (inputs[i].value.toLowerCase()=="skip"))
{
next = inputs[i];
break;
}
}
}
if(next==null)
{
for(i=0;i<inputs.length;i++)
{
if((inputs[i].value.toLowerCase()=="submit") || (inputs[i].name.toLowerCase()=="submit"))
{
next = inputs[i];
break;
}
}
}
if(next == null)
{
next = document.getElementById("submitbutton");
}
next.focus();
next.click();

Any help would be much appreciated.
