hi,

I need to extract the page numbers contained in a PDF.

ie If there are 4 pages in the PDF i need to extract the number 4 and use it for calcualtions on another piece of software in a continuous automated process.

Is this possible?

DG. :-)

Hi DG!

Yes. It's possible.

What's the next question? :)

Use one of the first step codes.

Put in a LoadFromFile...

...and then use function PageCount.

Cheers and welcome here,

Ingo

DG,

The second approach usig the DA functions will be the fastest as it doesn't need to load the entire file into memory.

QP.LoadFromFile("4pages.pdf", "");

int pageCount = QP.PageCount();

QP.RemoveDocument(QP.SelectedDocument());

int fh = QP.DAOpenFile("4pages.pdf", "");

int pageCount = QP.DAGetPageCount(fh);

QP.DACloseFile(fh);
