Javier,
In English measurements they are 10,000ths of an inch, in metric I
think they are 1000ths of a cm. You can test this by placing two fields onto the form, set show position on and put the second control 1 cm to the right and below the other and then look at the difference in values in the FRX.
>I'm trying to hack positioning fields in the FRX report table (vPos, hPos, height, and width) but I can't figure out what are the units in those fields. I would like to translate cm. to those units. Any hint is appreciated.
