get access to web form in IE

xof

Hi,

does anyone know, how to get access to web form in IE in C++ (I'm using Borland C++ Builder).
I want to read data from one IE window and write them in other window.

Example web form (HTML):






Below, I show an example web page, with form elements. Let's say, I have 2 the same window (both with this form). Then my application should read data from first window (from all 3 inputs) and write them in second window.
Is it posible to access this form elements like it is done in JavaScript (windowHandler.document.example.input1.value) ???
