 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.

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



 IMPORTANT:

  To work with Bytescout BarCode SDK you need to import this as a component into Delphi



 To import Bytescout BarCode SDK into Delphi 2006 or higher do the following:

 1) Click Component | Import Component..

 2) Select Type Library and click Next

 3) Find and select Bytescout BarCode SDK in the list of available type libraries and

 4) Click Next

 5) Click Next on next screen

 6) Select "Add Bytescout_BarCode_TLB.pas" into Project" and click Finish



 This will add Bytescout_BarCode_TLB.pas into your project and now you can use BarCode object interface (_BarCode class)



}



program Project1;



{$APPTYPE CONSOLE}



uses

  SysUtils,

  ActiveX,

  Bytescout_BarCode_TLB in 'c:\program files\borland\bds\4.0\Imports\Bytescout_BarCode_TLB.pas';



var

 bc: _Barcode;

begin

  CoInitialize(nil);  // required for console applications, initializes ActiveX support



  // create barcode object using CoBarCode class

  bc:= CoBarCode.Create();

  // set symbology to Code128

  bc.Symbology := SymbologyType_Code128;

  bc.Options.Code128Alphabet := Code128Alphabet_B; // set code 128 alphabet to B alphabet

  // set barcode value

  bc.Value:= '12345';

  // save into PNG image

  bc.SaveImage('Code128.png');

  // free barcode object by setting to nil

  bc:= nil;



  CoUninitialize(); // required for console applications, initializes ActiveX support



end.
