More information. I am using an ocx control and when I drop something on that control the ocx.DragDrop Function fires. The documentation says (the x and y values will identify the coordinates of the drop on the control. Note that these coordinates are in Twips and need to be converted (using Screen.TwipsPerPixelsX and Screen.TwipsPerPixelY) to pixels for use. ) The screen. calls are for VB.
