 IMPORTANT NOTICE for DELPHI 2007, Delphi 2006 or earlier versions:

 -----------------------------------------------------------------------

 Usual approach with type library import (so called "early binding") will crash with "stackoverflow" or "floating point error" due to issues in this versions of Delphi. 

 SOLUTION: Please use so called "late binding" that requires NO type library import and works by creating objects at the runtime like this:  

 // -----------------

 program Project1;

 uses

   SysUtils,

   ComObj,

   ActiveX;

 var

 extractor: Variant;

 begin

 CoInitialize(nil);

 // Create and initialize 

 extractor := CreateOleObject('Bytescout.PDFExtractor.CSVExtractor') ;

 // as usual 

 extractor.LoadDocumentFromFile ('../../sample3.pdf');

 // & 

 // destroy the object by setting to varEmpty

 extractor := varEmpty;  

 end.

 // -----------------  



}



program Project1;



{$APPTYPE CONSOLE}



{

 IMPORTANT:

  To work with Bytescout PDF Extractor SDK you may also use Late Binding



}



uses

  SysUtils,

  ComObj,

  ActiveX;



var

 extractor: Variant;

begin

 CoInitialize(nil);



 // Create and initialize Bytescout.PDFExtractor.CSVExtractor object using CoCSVExtractor class

 extractor := CreateOleObject('Bytescout.PDFExtractor.CSVExtractor') ; 

 extractor.RegistrationName := 'demo';

 extractor.RegistrationKey := 'demo';



 // Load sample PDF document

 extractor.LoadDocumentFromFile ('../../sample3.pdf');



// extractor.CSVSeparatorSymbol = ','; // you can change CSV separator symbol (if needed) from "," symbol to another if needed for non-US locales



 extractor.SaveCSVToFile ('output.csv');



 // destroy the extractor object

 extractor := varEmpty;



end.
