Hi Bruno,
As you said in the previous thread (Abhishek's):
"There are other ways to do it, and the book will give you
another example using setField and setFieldCache, but
the procedure described above is faster because it cuts
a lot of corners.
best regards,
Bruno"
I am exactly doing the same, I followed all your steps. Can you suggest me
how to use setField and setFieldCache for setting AcroForm fields over
multiple pages. If you can give me an example code, that will be great for
me.
Thanks in advance,
Ganesh.
