很简单的代码，:-D

unit Unit1; 
 
interface 
 
uses 
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, 
  Dialogs, StdCtrls; 
 
type 
  TForm1 = class(TForm) 
    Button1: TButton; 
    procedure Button1Click(Sender: TObject); 
  end; 
 
var 
  Form1: TForm1; 
 
implementation 
 
{$R *.dfm} 
 
procedure TForm1.Button1Click(Sender: TObject); 
var 
  bit: TBitmap; 
begin 
  bit := TBitmap.Create; 
  bit.Width := Width; 
  bit.Height := Height; 
  BitBlt(bit.Canvas.Handle, 0, 0, Width, Height, GetWindowDC(Handle), 0, 0, SRCCOPY);{就是这里了，:-)} 
  bit.SaveToFile('c:\temp\Form1.bmp');{temp目录必须事先存在那里才行。} 
  bit.Free; 
end; 
 
end.
