>Thank Mike, but I think it don't work (in this case)... Because I'd like when the user press TAB in the last object on page, the focus goes on to the first object...

In that case, there is another solution. Try to create a pageframe class, that will add antoher Line class to each page. In this Line class, use the UIEnable() event to set focus to teh first object in the page.

That means, no matter how it happens, whenever the page gets focus, the Line class will move the focus to the appropritate control.
