>thank for your reply. I got VFP 9.0 and I tried to do what I wanted to do. But its very difficult to obtain. Once I have the bidimensional array (almost one hundred values) with the nxcoord and nycoord (trapped in the mousemove event), I add the shape object to the form, I make it visible and put this code "thisform.myshape.polypoints='myarray'". Well, nothing appears! Is the shape very shy, or did I something wrong?
Maybe your array goes out of scope? Try to make it a property of the form.
