Convert MS Word document to PDF from Delphi using Word OLE automation.
The Word OLE (Delphi PDF) sample is a simple Windows console application that converts a MS Word document (*C:\Test.doc*) to PDF using Word OLE automation. The sample can be used to elaborate more complex code and applications with the novaPDF SDK.
Note: To be able to use the samples you must install novaPDF SDK as samples work only with it. Download it here: novaPDF SDK.
Sample Code:
program WordOLEDelphi;
{$APPTYPE CONSOLE}
uses
ActiveX,
Printers,
ComObj,
SysUtils,
Dialogs,
novaOptions in '..\..\..\include\novaOptions.pas',
novapiLIB80_TLB in '..\..\..\include\novapiLIB80_TLB.pas';
const
//name of novaPDF Printer
PRINTER_NAME = 'novaPDF SDK 8';
//Print profile name
PROFILE_NAME = 'Test OLE Delphi Profile';
PROFILE_IS_PUBLIC = 0;
var
hr : HRESULT;
pNova : INovaPdfOptions80;
strOldActiveProfileID : WideString;
strNewProfileID : WideString;
Word : VARIANT;
NewDoc : VARIANT;
begin
//initialize COM
hr := ActiveX.CoInitialize(nil);
if (FAILED (hr)) then begin
System.Writeln('Failed to initialize COM');
exit;
end;
//create one NovaPdfOptions instance
pNova := nil;
hr := ActiveX.CoCreateInstance(CLASS_NovaPdfOptions80, //CLSID_CNovaPdfSource,
nil,
CLSCTX_INPROC_SERVER,
IID_INovaPdfOptions80,
pNova);
if (FAILED(hr)) then begin
System.Writeln('Failed to create novaPDF COM object');
exit;
end;
//initialize NovaPdfOptions and pass printer name
pNova.Initialize2( PRINTER_NAME, '' );
pNova.SetDefaultPrinter();
// now the default printer is novaPDF printer but the Printer object is not updated
// here is a workaround to update the Printer object with the default printer
// you only need this code if you check later on the Printer.PrinterIndex to find out the default printer
//Printer.GetPrinter(Device, Driver, Port, DevMode);
//Printer.SetPrinter(PRINTER_NAME, Driver, Port, 0);
//create a new profile with default settings
pNova.AddProfile2(PROFILE_NAME, PROFILE_IS_PUBLIC, strNewProfileID);
//load the newly created profile
if (Length(strNewProfileID) > 0) then begin
pNova.LoadProfile2(strNewProfileID);
end else begin
System.Writeln('Failed to create profile');
exit;
end;
// set PDF document Title

pNova.SetOptionString2(NOVAPDF_SAVE_FOLDER, 'C:\');
