Eigenschaften eines Worddukuments auslesen und ändern

[chalasis]

Hallo Delphifreunde!
Ich habe folgende Frage :
Gibt es Funktionen mit denen man die Felder der Eigenschaften eines Worddokuments auslesen bzw. ändern (beisp. Feld Stichwörter) kann.

Danke

Hallo

Anbei mal 2 Möglichkeiten:

1. Via OLE

Delphi-Quellcode:

uses
  ComObj;

procedure TForm1.Button1Click(Sender: TObject);
const
  wdPropertyTitle = $00000001;
  wdPropertySubject = $00000002;
  wdPropertyAuthor = $00000003;
  wdPropertyKeywords = $00000004;
  wdPropertyComments = $00000005;
  wdPropertyTemplate = $00000006;
  wdPropertyLastAuthor = $00000007;
  wdPropertyRevision = $00000008;
  wdPropertyAppName = $00000009;
  wdPropertyTimeLastPrinted = $0000000A;
  wdPropertyTimeCreated = $0000000B;
  wdPropertyTimeLastSaved = $0000000C;
  wdPropertyVBATotalEdit = $0000000D;
  wdPropertyPages = $0000000E;
  wdPropertyWords = $0000000F;
  wdPropertyCharacters = $00000010;
  wdPropertySecurity = $00000011;
  wdPropertyCategory = $00000012;
  wdPropertyFormat = $00000013;
  wdPropertyManager = $00000014;
  wdPropertyCompany = $00000015;
  wdPropertyBytes = $00000016;
  wdPropertyLines = $00000017;
  wdPropertyParas = $00000018;
  wdPropertySlides = $00000019;
  wdPropertyNotes = $0000001A;
  wdPropertyHiddenSlides = $0000001B;
  wdPropertyMMClips = $0000001C;
  wdPropertyHyperlinkBase = $0000001D;
  wdPropertyCharsWSpaces = $0000001E;
const
  AWordDoc = 'C:\Test.doc';
  wdSaveChanges = $FFFFFFFF;
var
  WordApp: OLEVariant;
  SaveChanges: OleVariant;
begin
  try
    WordApp := CreateOleObject('Word.Application');
  except
    // Error....
    Exit;
  end;
  try
    WordApp.Visible := False;
    WordApp.Documents.Open(AWordDoc);
    WordApp.ActiveDocument.BuiltInDocumentProperties[wdPropertyTitle].Value := 'Your Title...';
    WordApp.ActiveDocument.BuiltInDocumentProperties[wdPropertySubject].Value := 'Your Subject...';
    // ...
    // ...
  finally
    SaveChanges := wdSaveChanges;
    WordApp.Quit(SaveChanges, EmptyParam, EmptyParam);
  end;
end;

2. Via Structured Storage

Delphi-Quellcode:

uses
  ComObj, ActiveX;

const
  FmtID_SummaryInformation: TGUID =
    '{F29F85E0-4FF9-1068-AB91-08002B27B3D9}';

function FileTimeToDateTimeStr(F: TFileTime): string;
var
  LocalFileTime: TFileTime;
  SystemTime: TSystemTime;
  DateTime: TDateTime;
begin
  if Comp(F) = 0 then Result := '-'
  else 
  begin
    FileTimeToLocalFileTime(F, LocalFileTime);
    FileTimeToSystemTime(LocalFileTime, SystemTime);
    with SystemTime do
      DateTime := EncodeDate(wYear, wMonth, wDay) +
        EncodeTime(wHour, wMinute, wSecond, wMilliseconds);
    Result := DateTimeToStr(DateTime);
  end;
end;

function GetDocInfo(const FileName: WideString): string;
var
  I: Integer;
  PropSetStg: IPropertySetStorage;
  PropSpec: array[2..19] of TPropSpec;
  PropStg: IPropertyStorage;
  PropVariant: array[2..19] of TPropVariant;
  Rslt: HResult;
  S: string;
  Stg: IStorage;
begin
  Result := '';
  try
    OleCheck(StgOpenStorage(PWideChar(FileName), nil, STGM_READ or
      STGM_SHARE_DENY_WRITE,
      nil, 0, Stg));
    PropSetStg := Stg as IPropertySetStorage;
    OleCheck(PropSetStg.Open(FmtID_SummaryInformation,
      STGM_READ or STGM_SHARE_EXCLUSIVE, PropStg));
    for I := 2 to 19 do
    begin
      PropSpec[I].ulKind := PRSPEC_PROPID;
      PropSpec[I].PropID := I;
    end;
    Rslt := PropStg.ReadMultiple(18, @PropSpec, @PropVariant);
    OleCheck(Rslt);
    if Rslt <> S_FALSE then for I := 2 to 19 do
      begin
        S := '';
        if PropVariant[I].vt = VT_LPSTR then
          if Assigned(PropVariant[I].pszVal) then

          8:  S  := Format('Last saved by: %s', [S]);
          9:  S  := Format('Revision number: %s', [S]);
          10: S := Format('Total editing time: %g sec',
              [Comp(PropVariant[I].filetime) / 1.0E9]);
          11: S := Format('Last printed: %s',
              [FileTimeToDateTimeStr(PropVariant[I].filetime)]);
          12: S := Format('Create time/date: %s',
              [FileTimeToDateTimeStr(PropVariant[I].filetime)]);
          13: S := Format('Last saved time/date: %s',
              [FileTimeToDateTimeStr(PropVariant[I].filetime)]);
          14: S := Format('Number of pages: %d', [PropVariant[I].lVal]);
          15: S := Format('Number of words: %d', [PropVariant[I].lVal]);
          16: S := Format('Number of characters: %d',
              [PropVariant[I].lVal]);
          17:; // thumbnail
          18: S := Format('Name of creating application: %s', [S]);
          19: S := Format('Security: %.8x', [PropVariant[I].lVal]);
        end;
        if S <> '' then Result := Result + S + #13;
      end;
  finally
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  if OpenDialog1.Execute then
    ShowMessage(GetDocInfo(OpenDialog1.FileName));
end;

Gibt es da noch eine Möglichkeit ohne COM bzw., dass Word installiert sein muss?
Auslesen würde völlig reichen.

Ich denke via Structured Storage sollte es funktionieren, auch wenn Word nicht installiert ist.
