Hi all. I have a PDF created in Adobe 7 (dunno if that matters). I loop through the fields and a call to GetFormFieldTitle(i) returns null for several fields.

Why would this be the case? Viewed in Acrobat 7 all fields do appear to have names.

Thanks.

Chris, for bug reports you have to send test pdf+program to identify your error. After we confirm your problem we can help you with more.

For Bug Report send email to

"support(at)quickpdf.org" or/and

"quickpdf(at)gmx.net"

The confirmation will be made in this news group.

Best Regards, Marian

Hi Chris!

What you wanna tell us with this posting?
This is "nonprofit" here. We're doing this here in our freetime (we all have other (main) jobs to do). Take it like the musceteers "one for all and all for one" ;-)
It's easy - if you don't get a reply then there's no solution. Perhaps you should wait a bit longer...

Best regards and a happy new year,
Ingo

Thank you Ingo,

Chris, what Ingo is telling is right. After almost 1 Year of no feedback (only from main group members) I have received 272 Emails in one month about quickpdf library. It is true that not all are bugs inside this library but it is impossible to answer to all (I have my own priorities). At the moment Ingo itself is waiting for another issue so you have to treat as with a little patience.

Chris, the email with bugs are important. Altough I may not aswer on your emails I always collect information about bug reports. Because your case is simple I may answer you this time.

Anyway it is good and recommended if you get no answer from us to come back and ask again for infos (as you did). We do make mistakes from time to time.

Your problem:

Your code use "PDF.FlattenFormField(i);". If you check the iSED documentation what it says about this function your will see the following:

[Quote]

FlattenFormField

Description

Use this function to draw the visual appearance onto the page it is associated with. The form field will then be removed from the document and only it's appearance will remain - it will no longer be an interactive field.

[Quote]

As you see your fields are deleted and if you use "for index := 0 to originalcount" with each FlattenedField your count decrease toward 50%.

With each call of your function you delete Trunc((originalcount + 1) / 2) fields from your document and on iteration you get no field after this position (index > Trunc((originalcount + 1) / 2)).

Best regards, and happy new year,

Marian

I didn't realize this was a volunteer effort, Marian, please forgive my impatience.

Thanks very much for your assistance. It seems to obvious now. ;)

chris, we are just trying to keep this library alive. Our reasons are different but we (me) are just doing our best.

About your impatience there is no problem. As long as we keep it friendly there is no reason to appologise. Because we don't use a bug tracking system it may happen to forget as well.

Well, one problem less for me.

For the others I have 4 more of them (Ingo, Fritz, anders_hg, ...)

..... stay tuned
