This is called panning and you can find an example in this thread - http://forums.ni.com/t5/LabVIEW/Move-picture-inside-of-the-picture-control/m-p/623697?view=by_date_d...

The Code Capture Tool also includes an example of this in its source code (the preview of the capture can be panned), which also demonstrates one way of handling only some of the mouse move events (which is important, because usually there are too many events and you want to discard some of them).
