How do i click this button in an IE created with autoit ? The button has no ID nor NAME ,it's not even a button at all i think. It opens a sub window to the login. That's how it looks :

These Script just open to page just direct connect to it and
post login formular.

TAG POS=1 TYPE=INPUT:TEXT FORM=ACTION: ATTR=ID:login_user_login CONTENT=Username
TAG POS=1 TYPE=INPUT:PASSWORD FORM=ACTION: ATTR=ID:user[password] CONTENT=Password
TAG POS=1 TYPE=BUTTON FORM=ACTION: ATTR=TXT:Submit

Than just submit over form... hope that fixxed ur problem ^^
