首先编辑 rc 文件如下(假定图片文件放在程序目录下的 img 文件夹下):
1 BITMAP img\bmpFile1.bmp
2 BITMAP img\bmpFile2.bmp

或者:
1,BITMAP,img\bmpFile1.bmp
2,BITMAP,img\bmpFile2.bmp

这次我们是给每个资源做了编号, 没有取标识名称; 然后在窗体上添加两个 Button, 代码如下:
unit Unit1;
interface
uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;
type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  end;
var
  Form1: TForm1;
implementation
{$R *.dfm}
var
  bit: TBitmap;
procedure TForm1.FormCreate(Sender: TObject);
begin
  bit := TBitmap.Create;
end;
//对只有编号的图片资源需要用 LoadFromResourceID 调用
procedure TForm1.Button1Click(Sender: TObject);
begin
  bit := TBitmap.Create;
  bit.LoadFromResourceID(HInstance, 1);
  Self.Brush.Bitmap := bit;
  Repaint;
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
  bit := TBitmap.Create;
  bit.LoadFromResourceID(HInstance, 2);
  Self.Brush.Bitmap := bit;
  Repaint;
end;
procedure TForm1.FormDestroy(Sender: TObject);
begin
  bit.Free;
end;
end.
