In your both library ICOSGALLERY and ICOSPOWERGALLERY not have none properties to move programaticly no?
IF you put those properties, I can simulate the swipe right and left throught the DPAD.
Look in example, works in Google Glass the swipe but throught the DPAD.
Imagine in yours libraries a property, something like that:
Dim g As ICOSGallery
g.SetSelection(4) <- Where 4 is the number of cell
Just like the property in listview
ListView1.SetSelection(4)
