Is there any way of read or write the value of an INPUT tag of type="text" or "password" of another SSL page?

i.e.
Imagine the secure site www.a.com with this source:
<HTML>
<BODY>
<FORM name=form1>
<INPUT type="text" name=text1>
</FORM>
</BODY>
</HTML>

Then in our page we have the following javascript order
winHandle= open("https://www.a.com", "window2")

How can I access/modify the value of the text box in this HTTPS page? If I try to use 'winHandle.document.form1.text1.value= 3' iExplore reports me an 'Access Denied' error.
