in your other post I reply a partial solution.

and if the website is a .aspx this solution has a code behind file, this need a iis server to run, if you use a shellexecute/process function to run this dont display the form indeed.

I recomend you use a simple html site and use a javascript functions, pass the value that you need thru the URL so http://mysite.htm?valor=casa

and later use a function for get this value when the html is loaded and pass this to the control.

cheers,
