Drop to HTML form field.

Does anyone know off the top of their heads if it's entirely possible to return the HTML field tag in a HTML document in IE, when something is dragged into if from a VB form.

I have the following HTML form as:

"<input type="text" name="url" size="50" maxlength="255" value="">"

I have a text box on my form, type in a URL and I can drag it into the input field in the IE HTML form. Just wondering if their is anyway to return back to my application the form field name (in this case name=url) ?

thanks!
