怎样将图象插入到Excel文件中呢？？

Question

我特意写了下面的demo，在我的D6/Excel2000中调试通过：
unit Unit1;interfaceuses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private
    { Private declarations }
    exApp,exWB,exSheet:Variant;
  public
    { Public declarations }
  end;var
  Form1: TForm1;implementationuses ComObj;
{$R *.dfm}procedure TForm1.Button1Click(Sender: TObject);
begin
  exApp:=CreateOleObject('Excel.Application');
  exApp.visible:=true;
  exApp.Caption:='Call Excel from Delphi';
  exWB:=exApp.workbooks.add;
  exSheet:=exWB.ActiveSheet;
  exSheet.Pictures.Insert('E:\My Pictures\1.jpg');
  
end;procedure TForm1.Button2Click(Sender: TObject);
begin
　　exApp.Quit;
    exWB:=Unassigned;
    exSheet:=Unassigned;
    exApp:=Unassigned;
end;end.
