>>It's not clear from your descripton what you want and what the problem is.

>>>I have a large form (let's call it Frm1) which covers almost fullscreen.
>>>Its layout propeties are:
>>>AlwaysOntop = .F.
>>>Desktop = .T.
>>>MDIForm = .F.
>>>ShowWindow = 0
>>>WindowState = 0
>>>
>>>I have buttons on Frm1 which bring up VFP's table designer and View designer
>>>The problem is those VFP designer always get blocked by this large form Frm1...
>>>Is there any way I can control layout properties of those VFP designer?
>>>
>>>In fact what I want is, if Frm1 is brought up, it must NOT be blocked by other windows except for those windows brought up by Frm1 itself... how would I achieve this?

>I need my Frm1 NOT to be blocked by other windows after it is launched except for its own child forms (brought up by clicking button on it). i.e. only its child forms can (and will always go on top of it, thus) block it... particularly when I click one of its button to bring up VFP table designer -- in this case, I consider the VFP table designer to be a child form of Frm1 and I need it to go on top of Frm1...

>My problem is, when I set my Frm1 layout properties as shown above, the VFP table designer always go behind Frm1 and I can't find a way to make the designer go on top of Frm1.
