Finding HTML elements/tags - vertical, horizontal positions X,Y by JS/VBS?

There is a Visual Basic 6 application with WebBrowser in it.

This application is about statistical information on what html tag was loaded, where it is being located - it's position X,Y

And one of the problems is I don't know how to find out vertical Y and horizontal X positions of iframes, frames, div tags, anchor href links and so on the loaded web page relatively to the screen and to the loaded html webpage...

Any ideas on how to find out X,Y positions?
