The DirectDrawSurface7.DrawRoundedBox method draws a rounded box on the surface.
object.DrawRoundedBox( _ 
    x1 As Long, _ 
    y1 As Long, _ 
    x2 As Long, _ 
    y2 As Long, _ 
    rw As Long, _ 
    rh As Long)
If the method fails, it raises an error, and Err.Number is set.
The default draw style is a solid line, and the default fill style is set to transparent. Both styles can be changed with a call to DirectDrawSurface7.SetDrawStyle and DirectDrawSurface7.SetFillStyle, respectively.
