!!!!高分求教ReadProcessMemory读取内存.有关内存偏移量的问题!

Question

已知一基地址$010EA0CC,偏移量为$2A4,先在用ReadProcessMemory函数连读取内存数据,为什么我用其他工具(例如:CE)可以读取到正常的数据，但
ReadProcessMemory(h,Pointer(addr+$2A4),@buf,nSize,lpNumberOfBytes);
却为0?是不是$010EA0CC是一个指针地址.请大家赐教procedure TForm1.Button1Click(Sender: TObject);
var gameHwnd:Hwnd;
    pid: dword;
    h: THandle;
    lpNumberOfBytes: DWord;
    buf:DWord;
    buf2:Pointer;
    Buffer : Array[0..3] Of DWord;
    addr:DWORD;
    nSize: DWORD;
    s:WideString;
    i:Integer;
begin
  gameHwnd:=FindWindow(nil,'Element Client');
  if gameHwnd<>0 then
    begin
      GetWindowThreadProcessId(gameHwnd, @pid);
      h:=OpenProcess(PROCESS_ALL_ACCESS, false, pid);
      if h<>0 then
        begin
          addr:=$010EA0CC;
          edit2.Text:=Inttostr(gameHwnd);
          edit3.Text:=Inttostr(h);
          nSize:=4;
          ReadProcessMemory(h,Pointer(addr+$2A4),@buf,nSize,lpNumberOfBytes);
          s:=inttoStr(buf);
          edit1.Text:=s;
          showmessage(s);
        end;
      closeHandle(h);
    end else begin
      showmessage('游戏未运行!');
    end;
end;

Answer 1

Return ValuesIf the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The function fails if the requested read operation crosses into an area of the process that is inaccessible. 看帮助 第一句话 函数成功的时候 这个值是非0 

Answer 2

不是。具体我也不太懂.我是在网上找到的一个函数搞定的,你看看能看懂不?讲一讲.我对内存这些东西是刚接触.很菜.
