Yes, I wrote that I know about that way, but how can I put several images on a form simultaneously ? I think it's impossible
It would be much easier could I just add event mousedown to the image-control. At PDA almost all control can be made only by pen, so it's nessesary to know the x-y of touch. But now that image-control can be used just as a Big Beautiful Button...
Well, another way - can I bring the form to the front and make it transparent to see background images and intercept touches ?
