de word a pdf

[nelem]

Hola estoy intentando pasar un documento word a pdf.

Muchas gracias

[Chris]

Yo lo hago con open office, desde delphi, mediante COM (a Open Office)

Tambien puedes instalar un controlador de impresora que hay por ahí que en vez de imprimir lo que hace es pasarlo a PDF.

Un Saludo.

Otra opción es usar algunas de las páginas en Internet que te lo convierten OnLine (PDFOnline, por ejemplo).

Hola D&W me podrias escribir algo del códigop o explicarme un poco mas es que no se a lo que te refieres.

Claro, ahí va:
Primero crea un unidad aparte....

unit ooo_Save2PDF;

interface

uses variants, ComObj, windows, SysUtils, StrUtils, ActiveX;

type
TOOOWriterEx = class(TObject)
private
fOpenOffice : Variant;
fDocument : Variant;
fConnected : boolean;
fDocumentOpened : boolean;
FOwnCreatedOLE : Boolean;
fDesktop : Variant;
function MakePropertyValue(PropName:string; PropValue:variant):variant;
public
Constructor Create;
destructor Destroy; override;
Property OLECreated : Boolean read FOwnCreatedOLE;
function Connect : boolean;
procedure Disconnect;
Procedure CloseActiveDoc;
function OpenDocument(Filename:string; invisible : Boolean = true):boolean;
Function SaveToPDF(pFileName: string):String;
Function SaveToHTML(FileName:String):String;
procedure SaveDocument(FileName: string);
procedure CloseDocument;
Function ConvertToPDF(DocumentFile, PDFFile : String; invisible : Boolean = true):String;
Function ConvertToHTML(DocumentFile, HTMLFile : String; invisible : Boolean = true):String;
end;

implementation
Uses Dialogs;

{ TOOOWriterEX }

procedure TOOoWriterEx.CloseDocument;
begin
if fDocumentOpened then
begin
fDocument.Close(false);

fDocumentOpened := false;
fDocument := Unassigned;

fDesktop.Terminate;
fDesktop := UnAssigned;
end;
end;

Procedure TOOoWriterEx.CloseActiveDoc;
begin
if fDocumentOpened then
fDocument.Close(false);
end;

function TOOoWriterEx.Connect: boolean;
begin
if VarIsEmpty(fOpenOffice) then
Begin
{ Try
fOpenOffice := GetActiveOleObject('com.sun.star.ServiceManager');
FOwnCreatedOLE := False;
Except }
Try
fOpenOffice := CreateOleObject('com.sun.star.ServiceManager');
FOwnCreatedOLE := True;
Except
Begin
ShowMessage('No se ha podido iniciar el objeto OLE para la conección a OpenOffice.'+#13+
'Verifique que el sitema OpenOffice esté instalado adecuadamente en su equipo.');
Exit;
end;
end; // fin de try
// end;
end;

fConnected := not (VarIsEmpty(fOpenOffice) or VarIsNull(fOpenOffice));
Result := fConnected;
end;

constructor TOOoWriterEx.Create;
begin
inherited;
CoInitialize(nil);
end;

destructor TOOoWriterEx.Destroy;
begin
CoUninitialize;
inherited;
end;

procedure TOOoWriterEx.Disconnect;
begin
if fDocumentOpened then
CloseDocument;

fConnected := false;
fOpenOffice := Unassigned;
end;

function TOOoWriterEx.MakePropertyValue(PropName: string;
PropValue: variant): variant;
var
Struct: variant;
begin
Struct := fOpenOffice.Bridge_GetStruct('com.sun.star.beans.PropertyValue');
Struct.Name := PropName;
Struct.Value := PropValue;
Result := Struct;
end;

function TOOoWriterEx.OpenDocument(Filename: string; invisible : Boolean = true): boolean;
var
wProperties : Variant;
begin
if not fConnected then
abort;
fDesktop := fOpenOffice.createInstance('com.sun.star.frame.Desktop');
wProperties := VarArrayCreate([0, 0], varVariant);
wProperties[0] := MakePropertyValue('Hidden', invisible);

fDocument := fDesktop.loadComponentFromURL( 'file:///'+ AnsiReplaceText(ExpandFileName(FileName),'\','/')
, ' _blank', 8, wProperties);

fDocumentOpened := not (VarIsEmpty(fDocument) or VarIsNull(fDocument));
result := fDocumentOpened;
end;

Function TOOoWriterEx.SaveToPDF(pFileName: string):String;
var
wProperties: variant;
begin
Result := '';
if not (fConnected and fDocumentOpened) then
abort;

wProperties := VarArrayCreate([0, 0], varVariant);
wProperties[0] := MakePropertyValue('FilterName', 'writer_pdf_Export');

try
fDocument.StoreToURL('file:///'+ AnsiReplaceText(ExpandFileName(pFileName),'\','/'), wProperties);
except on E: EOleException do
Result := E.Message;
end;

end;

Function TOOoWriterEx.SaveToHTML(FileName:String):String;
var
wProperties: variant;
begin
if not (fConnected and fDocumentOpened) then
abort;

wProperties := VarArrayCreate([0, 0], varVariant);
wProperties[0] := MakePropertyValue('FilterName', 'HTML (StarWriter)');

try
fDocument.StoreToURL('file:///'+ AnsiReplaceText(ExpandFileName(FileName),'\','/'), wProperties);
except on E: EOleException do
Result := E.Message;
end;
end;

procedure TOOoWriterEx.SaveDocument(FileName: string);
var
wProperties: variant;
begin
if not (fConnected and fDocumentOpened) then
abort;

wProperties := VarArrayCreate([0, 0], varVariant);
wProperties[0] := MakePropertyValue('FilterName', '');

fDocument.StoreToURL('file:///'+ AnsiReplaceText(FileName,'\','/'), wProperties);
end;

Function TOOoWriterEx.ConvertToPDF(DocumentFile, PDFFile : String; invisible : Boolean = true):String;
Begin
Result := '';
If Not fConnected Then Connect;
If OpenDocument(DocumentFile) Then
Result := SaveToPDF(PDFFile);
CloseActiveDoc;
end;

Function TOOoWriterEx.ConvertToHTML(DocumentFile, HTMLFile : String; invisible : Boolean = true):String;
Begin
Result := '';
If Not fConnected Then Connect;
If OpenDocument(DocumentFile) Then
Result := SaveToHTML(HTMLFile);
CloseActiveDoc;
end;

end.


Para utilizarlo:

Procedure Convertir_aPDF(wordFile, PDFFile:TFileName);
var
FOOOInterface : TOOoWriterEx;
Begin
Try
FOOOInterface := TOOoWriterEx.Create;
FOOOInterface.ConvertToPDF(wordFile,PDFFile);

If FOOOInterface.OLECreated Then
Begin
FOOOInterface.CloseDocument;
FOOOInterface.Disconnect;
end;

Finally
FOOOInterface.Free;
end;
end;


Ese es un ejemplo, no estoy seguro de que servirá porque es una extracción rápida del código que utilizo en mis programas, pero pruebalo.

Saludos.
