I'm using fpdf library and there's no output produce after I run the code.. What's the problem and how can I resolve it?
Note: It also produces no errors, so it's so hard to fix the bug

I have some code that reads pdf files. The code fails at the line :
iTextSharp.text.pdf.PRTokeniser.CheckPdfHeader() at
iTextSharp.text.pdf.PdfReader.ReadPdf()
I know from other entries that this issue is coming from some invalid formatting in the pdf. However I'm not in a position to tell my users to redo their pdfs. Is there some other way around this issue, that can allow reading of the pdf despite this problem?
If a file doesn't start with %PDF- then there's nothing to fix: the file isn't a PDF file.
However, there may be another problem: maybe you're trying to access a file that has zero length due to some problem while creating the InputStream. Another context in which I've seen this happen, is a PDF loaded from a server, where the server returned a 404 message in HTML instead of a PDF file ;-)
Whenever that exception happens, you should store the bytes somewhere, and examine them. Without those bytes, nobody will be able to give you useful advice.
My FPDF was working nicely but suddenly it is making problem to generate pdf file.
Now when i am going to generate pdf it is showing an error
"FPDF error: File is encrypted!"
What is the problem? How can I fix it?
I have already tried with like this:
ini_set("pcre.backtrack_limit", "1000000000");
ini_set('memory_limit', '1024M');

Hopefully, Chris Noe, is in the house...
Selblocks is an extension for Selenium IDE that provides control-flow constructs such as if/then/else, looping and subroutines.
I'm trying to give interation over an XML file a whirl and am running into an error. It seems it can't find the XML file. The XML file is co-located with my Sel scripts. Please see the screenshot attached.
Is there a source for more documentation or examples? Like the sample test suite you have a picture of on the extension page?
Thanks,
Cameron

I ran into the same issue, and the problem turned out to be that my XML was invalid. In my case it was because one of the parameters I was using was a url containing ampersands. Changing & to & fixed the problem for me, and the variables loaded perfectly.
I've been using the code sample from iText in Action (8.7.2) to deal with the "cannot save" issue with PDF forms and iTextSharp. It was working fine, but recently the fix stopped working and all the variations of the code listed in the book to prevent the saving problem haven't solved it.
I'm using the latest version of the iTextSharp library. Has anyone else run into this? Did an Acrobat update break it?
works for me using iTextSharp 5.0.6, Reader X, and Listing 8.29 ReaderEnabledForm from the book. (it's the file named 'xfa_preserved.pdf' in the zip download)
IIRC the last couple of times i saw similar on the mailing list, the problem was specific to how the original PDF was created. if you subscribe, you can post the original PDF and hopefully one of the experts can take a look if they have time.
