[hery]

Dim workspace(1 To 4) As Long ' (1)=left (2)=top (3)=right (4)=bottom
    SystemParametersInfo &H30, 0, workspace(1), 0 ' &h30 = get workspace size
    Dim X As Long, Y As Long, w As Long, h As Long
    X = workspace(1) * Screen.TwipsPerPixelX
    Y = workspace(2) * Screen.TwipsPerPixelY
    w = workspace(3) * Screen.TwipsPerPixelX - X
    h = workspace(4) * Screen.TwipsPerPixelY - Y
    Move X + 0.1 * w, Y + 0.1 * h, 0.8 * w, 0.8 * h ' 10% margins

I take 80% of the working space size (10% left + 10%right = 20%) and center the form. Its the same thing, my math is just a little different. By making the form 80% of the working space then centering it ... it will leave 10% on each edge
