>Thanks, Martina. The thing is that Anchor works fine for moving and resizing the controls on the form. What we're trying to do is manage the size of the form itself and keep it in the same ratio.

Hi Tamar.

What I do is to put anything into an otherwise useless borderless transparent container, and let the forms Resize .MOVE() this container so that it keeps it's ratio and centres it as good as possible. (keep top left is more ugly). So there is little maths in forms resize. The containers Resize does not fire twice as with WIDTH and HEIGHT props.
The container itself must take care of the objects contained, but can trust its ratio, what makes the maths more easy.
