以下是打开word的一段code;
procedure TForm1.Button1Click(Sender: TObject);
var
  ItemIndex :OleVariant;
  FileName, ConfirmConversions, ReadOnly, AddToRecentFiles,
  PasswordDocument, PasswordTemplate, Revert,
  WritePasswordDocument, WritePasswordTemplate, Format,encoding,visible: OleVariant;
beginif not OpenDialog1.Execute then
  Exit; {Open document}
  FileName:= OpenDialog1.FileName;
  ConfirmConversions:= False;
  ReadOnly:= False;
  AddToRecentFiles:= False;
  encoding:=true;
  PasswordDocument:= '';
  PasswordTemplate:= '';
  Revert:= True;
  WritePasswordDocument:= '';
  WritePasswordTemplate:= '';
  Format:= wdOpenFormatDocument;  WordApplication1.Documents.Open(FileName,ConfirmConversions,ReadOnly,AddToRecentFiles,PasswordDocument,PasswordTemplate,Revert,WritePasswordDocument,WritePasswordTemplate,Format,Encoding,visible);
  ItemIndex:=1;
  WordDocument1.ConnectTo(WordApplication1.Documents.Item(ItemIndex));
  WordApplication1.Visible:=True;  {Turn Spell checking of because it takes a long time if enabled and slows down Winword}
  WordApplication1.Options.CheckSpellingAsYouType := False;
  WordApplication1.Options.CheckGrammarAsYouType := False;
end;
