printpdf() returns -2

  • Hello,

    I'm trying to use printPdf function but it returns a code -2, I guess it points out a problem with the license.

    I have WPViewPDF V3 PLUS installed

    Declaration:

    Code
    function pdfPrint(filename: PChar; password: PChar; licname, lickey: PChar; liccode: Cardinal; options: PChar): Integer; stdcall; external 'wPDFViewPlus03.dll' name 'pdfPrint';

    Implementation:

    Code
    ShowMessage(inttostr(pdfprint(PChar(fileName), 'L9XX-XXXX-XXXX-XXX',
          'Krxxxxxxxxxxxxxxx', 'D=XX-XXXX-XXXX-XXXX', 17XXXXX, 'DIALOG=1')));

    Can you help ?
