Chau,
1) On forms you can use the Line method to draw lines. See also DrawMode property, DrawStyle property, DrawWidth property.
2) Under the IDE you can also simply draw lines, boxes, circles, etc on your forms and reports using the appropiate drawing tool from the form toolbar.
Lines and shapes can be drawn over other images and objects on the form or report.
>Do anyone know that VFP can draw directly lines and enter character on jpg image? eg. Using in shipping marks on invoice or packing list.
