VB program accessing a javascript variable
i critically need to know how a visual basic program can retrieve a javascript variable and display it. Please help me. Thanks :)
example of a js file :
function run()
{
i = 0;
document.write('Value : ' + i);
}
//////////////////////////
a HTML file
<html>
<head></head>
<body onload="run();">
<!-- this is the part where i want the visual basic program to change the value of i into another value after document.write has done its work -->
</body>
</html>

Try read the value in a Hidden Field, then vb might able to change it using the webbrowser control.

Sorry, i dont get what u mean. But the value captured will still be inside the memory. Thats what puzzled me. How does the VB program knows what value to capture from the memory since the javascript store the hidden value inside the computer. And also the javascript cannot have any file access. I try not to use Jscript as it is too confusing
