I'm seconds away from purchasing a license as well as releasing a very standard ASPX example to the community with a very common usage situation:

Person views PDF on prior page

Person selects Printer name from drop down

PDF prints on next page with a "ajax style animated gif" while it prints.

One problem. I'm printing the PDF using the active x PrintDocument call from this page:

http://www.quickpdflibrary.com/help/quickpdf/PrintDocument.php - http://www.quickpdflibrary.com/help/quickpdf/PrintDocument.php

Unfortunately it requires page number information. My use case is that 100% of the time the pageCount is never cared about or known.

Is there a -1 or 0 or something that we can pass in as to not have to know about it?

Function QuickPDF0718.PDFLibrary::PrintDocument(PrinterName As String,
StartPage As Long, EndPage As Long, Options As Long) As Long

So do you want to print all pages in the document? I presume that's the case since any other option doesn't make sense from what you've described so far.

You have to include a start page and an end page, but this is simple. The start page is 1 and to get the end page you simply call QP.PageCount() which will return the total number of pages in the document as an int -- the total number of pages is equal to the last page in the document.

E.g. QP.PrintDocument(GetPrinterName, 1, QP.PageCount(), GetPrintOptions);

HTH!

Thanks for the tip. I was looking for a quick way to get the page count. Obviously missed a very easy function call.

BTW< tested and works perfectly. I'll release my demo code shortly.
