 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;



uses

  Forms,

  Unit1 in 'Unit1.pas' {Form1};



{$R *.res}



begin

  Application.Initialize;

  Application.CreateForm(TForm1, Form1);

  Application.Run;

end.
