    Re: Looping through all controls on a form.

    It isn't massively different, but I expect it would run a little bit slower (to a level that is totally ignorable in almost all projects).

    Re: Looping through all controls on a form.

    All ways will use basically the same concepts, except potentially avoiding recursion (which can be hard to get your head around to start with).
