Drag control with auto scroll

[george 16-17]

Greetings all,

I have multiple images on an unbound form that I can drag and drop to
rearrange their order. That part works fine. The only issue I am having is
when I attempt to drag image past the form's current view. I need the
vertical scrollbar to scroll up or down automatically while dragging, which
it does not do. Is there a method to have form automatically scroll?

I hope this make sense and any assistance is appreciated.

Thanks in advance,
george
