用 MapFileAndCheckSum 函数检测 exe 或 dll 是否被修改

 问题来源: http://www.cnblogs.com/del/archive/2008/12/08/1350440.html#1395177

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}

uses ImageHlp; {MapFileAndCheckSum 定义在这个单元}

procedure TForm1.Button1Click(Sender: TObject);
const
  exeFile = 'c:/windows/system32/notepad.exe'; {exe or dll}
var
  size1,size2: Cardinal;
begin
  MapFileAndCheckSum(exeFile, size1, size2); 
  ShowMessageFmt('原生大小: %d; 修改后大小: %d', [size1,size2]);
  {函数返回 0 表示已顺利检测, 但还要判断 size1、size2 是否相等}
end;

end.
