Save file through the _IEFormElementGetObjByName

Hello all..

Is there any way to save a document through the object?

E.g

$o_form = _IEFormGetObjByName($oIE, "Form1");Form1_ctl0
$o_btnSair = _IEFormElementGetObjByName($o_form, "btnSair")
$o_gareLink = _IEFormElementGetObjByName($o_form, "gareLink")

The "gareLink" is the object.

I tryied InetGet but didnt work to this case, because each time will be a different name of the document (link to download)
