参数传递是很奇怪，有时候会无法启动，比如：

CreateProcess（"c:\\a.exe","aa bb cc",....),显示出错

通过CreateProcess("c:\\a.exe", "\"c:\\a.exe\" c:\\a.exe aa bb cc"...)即可.



HANDLE hRead,hWrite;  SECURITY_ATTRIBUTES sa;  sa.nLength=sizeof(SECURITY_ATTRIBUTES);  sa.bInheritHandle=true;  sa.lpSecurityDescriptor=NULL;  if(!::CreatePipe(&hRead,&hWrite,&sa,0))  {  AfxMessageBox("CreatePipe failed!");  return false;  }  STARTUPINFO si;  si.cb=sizeof(STARTUPINFO);  GetStartupInfo(&si);   si.dwFlags=STARTF_USESHOWWINDOW|STARTF_USESTDHANDLES;  si.wShowWindow=SW_HIDE;//这里设置是否显示DOS窗口  si.hStdError=hWrite;  si.hStdOutput=hWrite;  si.hStdInput=GetStdHandle(STD_INPUT_HANDLE);  PROCESS_INFORMATION pi;  LPSTR lpszCmdLine="cmd sname ...";//这里你自己修改吧。  if(!CreateProcess(NULL,lpszCmdLine,NULL,NULL,TRUE,0,NULL,0,&si,&pi))  {  AfxMessageBox("CreateProcess failed!");  CloseHandle(hRead);  CloseHandle(hWrite);  return false;  }  CloseHandle(hWrite);  if(WaitForSingleObject(pi.hProcess,5000)==WAIT_TIMEOUT)  {  AfxMessageBox("Timeout!");  TerminateThread(pi.hThread,1);  TerminateProcess(pi.hProcess,1);  CloseHandle(hRead);  return false;  }  char buf[4096]={0};  DWORD bytes;  if(::ReadFile(hRead,buf,4095,&bytes,NULL)==NULL)//读取程序输出  {  AfxMessageBox("ReadFile Failed!");  CloseHandle(pi.hThread);  CloseHandle(pi.hProcess);  CloseHandle(hRead);  return false;  }  else   {          Result=buf;  }  CloseHandle(pi.hThread);  CloseHandle(pi.hProcess);      CloseHandle(hRead);  return true; 用CreateProcess创建进程，用管道读取程序输出。用GetExitCodeProcess读取程序退出代码
