You can convert it from auto hidden to be docked again by using MakeDockedRequest(...) if you know it is currently auto hidden. You can find the current state of a page by using FindPageLocation(...).
what can i do with the FindPageLocation(), i am sure that the page is set to autohidden, but it is collapsed, can i call the function that perform the autohiden request programmatically ???
You cannot cause the auto hidden page to scroll out into view in the same way as when the user moves the mouse over the auto hidden tab. I will add this feature request to the wishlist.
