You need an object reference to that window, which you can have if you have created it. The simplest way is to add a browser control to your form - from there, the complete document model of the currently displayed web page is available. Beware - there are multiple, even overlapping collections of objects, and you should look up the html source to find the name of the object you want. Often a quite simple page has hundreds of elements.
