学习使用资源文件[3] - 用 Image 显示资源中的图片

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):

bmp1 BITMAP img\bmpFile1.bmp

bmp2 BITMAP img\bmpFile2.bmp

或者:

bmp1,BITMAP,img\bmpFile1.bmp

bmp2,BITMAP,img\bmpFile2.bmp

然后在窗体上添加一个 Image、两个 Button, 代码如下:

unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ExtCtrls, StdCtrls;

type
TForm1 = class(TForm)
Image1: TImage;
Button1: TButton;
Button2: TButton;
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
end;

var
Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
Image1.AutoSize := True;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
Image1.Picture.Bitmap.Handle := LoadBitmap(HInstance, 'bmp1');
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
image1.Picture.Bitmap.LoadFromResourceName(HInstance, 'bmp2');
end;

end.
