写了一个简单程序测试通过：）
}
program Test1;

//{$APPTYPE CONSOLE}

uses
  SysUtils,
  Classes,
  MemoryRunUnitTwo in 'MemoryRunUnitTwo.pas';

var
    ABuffer: array of byte;
    Stream: TFileStream;
    ProcessId: Cardinal;
begin
    Stream := TFileStream.Create('HT.exe', fmOpenRead);
    try
        SetLength(ABuffer, Stream.Size);
        Stream.ReadBuffer(ABuffer[0], Stream.Size);
        MemoryRunExe(@ABuffer[0]);
    finally
        Stream.Free;
    end;
end.
