  ProcInfo: TProcessInformation;

  Path: array [0..MAX_PATH] of char;

begin

  //create process to inject into

  ZeroMemory(@StartInfo, SizeOf(TStartupInfo));

  StartInfo.cb := SizeOf(TStartupInfo);

  CreateProcess(nil, 'notepad.exe', nil, nil, False, 0, nil, nil, StartInfo, ProcInfo);

  Sleep(100);

  //inject the dll into the process

  Process := ProcInfo.hProcess;

  InjectLibrary(Process, 'test.dll');

  Sleep(3000);

  //kill the process

  TerminateProcess(Process, 0);
