我的一个朋友在微软源码中意外发现了如下代码：

 

//Function:  RunCommandEx

//Synopsis:  runs the given command in the current session, more robust

//  than RunCommand

//Arguments:  none

//Returns:  S_OK if success

//History:  October 3, 2000 - created [name withheld to protect the guilty]

 

HRESULT RunCommandEx(LPCWSTR szCmdLine)

{

  Dword dwTry = 0;

  HRESULT hResult = S_OK;

 

  //try run command 3 times at most

  while (dwTry<4)

  {

  hResult = RunCommand(szCmdLine);

  if (hResult!=E_FAIL)

  {

  //we succeeded

  break;

  }

  dwTry++;

  }

  if (dwTry==4)

  {

  ATLTRACE(L"COuld start the command even we tried 4 timesn");

  //译注：或许Chris的本意是

  //ATLTRACE(L"Couldn't start the command even we tried 4 timesn");

  ASSERT(FALSE);

  }

  return hResult;

}

 

这并非我所指的强健，但也不错...
