该死的DELPHI 变量申明 和内存读取

贴段代码：

//-------------------------注入代码的函数----------------------------
{参数说明:
InHWND:被注入的窗口句柄
Func:注入的函数的指针
Param:参数的指针
ParamSize:参数的大小
}
procedure InjectFunc(InHWND: HWND; Func: Pointer; Param: Pointer; ParamSize: DWORD);
var
  hProcess_N: THandle;
  ThreadAdd, ParamAdd: Pointer;
  hThread: THandle;
  ThreadID: DWORD;
  lpNumberOfBytes:DWORD;
begin
  GetWindowThreadProcessId(InHWND, @ThreadID);  //获得窗口ID
  hProcess_N := OpenProcess(PROCESS_ALL_ACCESS, False, ThreadID);//打开被注入的进程
  ThreadAdd := VirtualAllocEx(hProcess_N, nil, 4096, MEM_COMMIT, PAGE_READWRITE);  //申请写入代码空间
  WriteProcessMemory(hProcess_N, ThreadAdd, Func, 4096, lpNumberOfBytes); //写入函数地址
  ParamAdd := VirtualAllocEx(hProcess_N, nil, ParamSize, MEM_COMMIT, PAGE_READWRITE);  //申请写入代码参数空间
  WriteProcessMemory(hProcess_N, ParamAdd, Param, ParamSize, lpNumberOfBytes); //写入参数地址
  hThread := CreateRemoteThread(hProcess_N, nil, 0, ThreadAdd, ParamAdd, 0, lpNumberOfBytes); //创建远程线程
  ResumeThread(hThread); //直接运行线程
  CloseHandle(hThread); //关闭线程

// 根据小金鱼修改后的代码修改来的
  VirtualFreeEx(hProcess_N, ThreadAdd, 4096, MEM_RELEASE);
  VirtualFreeEx(hProcess_N, ParamAdd, ParamSize, MEM_RELEASE); //释放申请的地址

CloseHandle(hProcess_N); //关闭打开的句柄
end;

//-----------------------------定义一个参数类型-----------------------
