I have problem with checkboxes.
Different versions of Quick PDF differently read theirs properties.

I used same PDF, same code to read same properties with versions 9.11, 9.13, 9.16 and 10.14.
Result are not the same.

Does anyone know anything about that?

dsola,

There have been many changes and improvements with check boxes in 9.x and 10.xx versions. These change are now complete. They were changed because of inconsistencies in the functions and SubNames were being used instead of KidNames in various places and it needed cleaning up especially when it came to Radio fields.

If a field is of type Radio then each item is a Kid and you use the Kid functions to access each button. For each button there are On an Off values and there are the SubNames. For a Choice field the choices are in the SubNames.

In previous versions the Kids and SubNames were getting mixed up.

I would recommend sticking to one of the more recent versions.

Andrew.
