Hope you'll help me to cope with this problem. I work with MapX 4.5 in PowerBuilder 8. I want my program to highlight nodes in polylines, which are the closest to mouse pointer. So that I could while drawing a new polyline snap it's node to existing one and show to a user - to what point it's snapped to.
Problem #1 I get mouse coordinates into ocx_x, ocx_y. Map1.Object.ConvertCoord (ocx_x, ocx_y, X1, Y1, miScreenToMap) As far as I see into X1,Y1 should be set into Map Coordinates. Ups... Why zeros???? This function with parameter mimaptoscreen works the same. Is it a bug or my hands? Problem #2 Has anybody already worked with such a problem - highlighting nodes. My realization works so slow - could anyone propose a decision. Thanks a lot I'll be your obligator if you help me Best Regards, Katerinka --------------------------------- Do you Yahoo!?
