Hi Sergey,
I found that _Screen.Height-Sysmetric(4)*2-Sysmetric(9) gives me the height of a Maxiimized Form and _Screen.Width-Sysmetric(3)*2 gives me the width.
Do you see anything wrong with these Calculations?


>Try following

DECLARE INTEGER LockWindowUpdate IN WIN32API INTEGER lnHandle

>lnWidth = Thisform.Width
>Thisform.WindowState=2
>Thisform.Width = lnWidth
>Thisform.AutoCenter= .T.
>LockWindowUpdate(0)
>

I don't see any flickering or flashing when I use this code.

Thisform.LockScreen = .T.
>>>lnWidth = Thisform.Width
>>>Thisform.WindowState=2
>>>Thisform.Width = lnWidth
>>>Thisform.AutoCenter= .T.
>>>Thisform.LockScreen = .F.
