JavaScript Variable visibility from C#

May I ask for your help?

The C-Sharp environment is still new for me and the learning curve has been steep.In any event, I am attempting to obtain visibility ofJS variablesfrom javascript calls sent to a web-site's server from within it's HTML. I have attempted to obtain this visibility through the different flavors of the IHTMLDocument ( , 2, 3, 4 and 5) interfaces, with references to "microsoft.mshtml" and "Interop.SHDocVw", and although I can see all of the variables of the HTML, I don't seem to have the visibility of the JavaScript calls variables.

Is the use of IHTMLDocument (and it's different iterations) the right direction? If so, which IHTMLDocument iteration should I be using ( , 2, 3, 4, 5)? It appears that IHTMLDocument2 and IHTMLDocument3 provide the greatest visibility to a website's HTML information, however it doesn't seem to provide any access to the underlying JavaScript calls.

Is there possibly a better way to gather this information?

Thanks in advance,

Bill Hunter
