Hi. I have filled out form California form 540 ([url]http://ftb.ca.gov/[/url]
forms/06_forms/06_540.pdf) using iSEDQuickPDF
([url]http://www.isedquickpdf.com/[/url]). The original California form 540 is
editable. But the file that I generate from iSEDQuickPDF is read-
only, and none of the form fields that I filled in show up (all the
values are empty).

However, if I open the filled PDF file with PDFFill (http://
[url]www.pdfill.com/[/url]), the values show up, and also can be edited.

For the federal 1040 form ([url]http://www.irs.gov/pub/irs-pdf/f1040.pdf[/url])
filled out by iSEDQuickPDF, the form is read-only, but the values of
the form fields do show up.

So what can be done?

It seems iSEDQuickPDF is shut down (no updates, no support). So are
there any free tools for C/C++ to fill out form fields?

Thanks.
