AcroPDF print in reverse order

[haidomingo]

Hi,
I use AcroPDF.dll : AcroPDF.printAll;
Now I want to print in reverse order.
I could use the function AcroPDF.printPages (LastPage, FirstPage).
How can I get the total number of pages in the PDF document? (lastPage?).
I found with google this dll
This Counts the total number of pages of pdf file.
Unfortunately the call to the DLL returns always -1.
The code of dll is: Titel der Webseite
The code is not compatible with Delphi 2010.
Is there another way to print in reverse order?

Thanks.

Try PAnsiChar instead of PChar in the call

Zitat von mkinzler:

I changed:

function GetPdfPageCount(filename: pchar): integer; stdcall; external 'PdfPageCount.dll'; to
function GetPdfPageCount(filename: PAnsiChar): integer; stdcall; external 'PdfPageCount.dll'; and call:

..GetPdfPageCount(PAnsiChar('C:\Progetti\Totem\file.pdf'))...
and now it works perfectly.

Really simple (stupid me).

Thanks
