This code is designed for controls that have multiple layers of group boxes. When iterating through controls on a form, one must remember that groupboxes hide controls within it. Making an interation that is only for the form, unable to see those controls. Depending on how many panels, groupboxes, tabs, split containers or any other container, you must remember to iterate through those controls as well.
