AW: PDF Creator innerhalb Delphi nutzen

  Alt 1. Jul 2010, 18:39
Folgender im Netz gefundener Sourcecode als Beispiel für eine späte Bindung funktioniert:
Delphi-Quellcode:
unit uPDFCreator;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ActiveX, ComObj, Mask, JvExMask, JvToolEdit;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    ButtonExecute : TButton;
    procedure ButtonExecuteClick(Sender: TObject);
  private
    PDFCreator, MSWord: OleVariant;
    optUseAutosave, optUseAutoSaveDirectory, optAutosaveFormat,
    optPDFColorsColorModel: Integer;
    optAutosaveDirectory, optAutosaveFilename: String;
    // Security Options
    optPDFUseSecurity, optPDFHighEncryption, optPDFOwnerPass: Integer;
    optPDFDisallowCopy, optPDFDisallowModifyAnnotations,
    optPDFDisallowModifyContents, optPDFDisallowPrinting: Integer;
    optPDFAllowAssembly, optPDFAllowDegradedPrinting, optPDFAllowFillIn,
    optPDFAllowScreenReaders: Integer;
    optPDFOwnerPasswordString: String;
    procedure StorePDFOptions;
    procedure SetPDFOptions(const filename, ownerpass: String);
    procedure RestorePDFOptions;
  public

  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.ButtonExecuteClick(Sender: TObject);
const

         c := PDFCreator.cCountOfPrintJobs;
      end;

      MSword.ActiveDocument.Close(SaveChanges := 0);
   finally
      VarClear(MSWord);
   end;

   RestorePDFOptions;

end.
Ich hätte aber gern die frühe Bindung eingesetzt (wie z.B. im PDFCreator COM Sample für C# gezeigt), leider funktioniert dieses nicht, wenn ich es in Delphi umsetze. Der Vorteil wäre, dass man dann auf Ereignisse wie OnError und OnReady reagieren könnte.

Eins noch: Der o.a. Quellcode funktionierte bei mir erst dann, als ich den PDFCreator-Druckertreiber auf Direktdruck gestellt habe. Kenn jemand eine Möglichkeit, dies vom Programmcode aus einzustellen?
