I have a project with many child windows of the same form.
A child window contains a picture box with a given variable size.
The width-to-height ratio is fixed.
How can I fix this ratio from the child window?
How can I include a zoom function to zoom (in/out) the picture box?
If the picture box is greater than the child window: scrollbars are needed.
-->How can I change the size of the child window and the picture box?
How can I arrange the windows: i.e. arrange horizontal/vertical: how can i say: the first window left: the last window right....
