程序调用plink.exe发送命令设置路由

项目要求程序调用cmd.exe然后执行plink.exe登录到路由器，然后执行路由器的命令对其进行设置。本体和cmd.exe交换数据，发送命令到cmd.exe然后从其获取执行的结果进行判断。代码如下：

初始化代码：

BOOL CMotorolaSetDlg::OpenCMDProcess(){    SECURITY_ATTRIBUTES sa;    STARTUPINFO si;    TCHAR cmdLine[256] = {0};    TCHAR wcRcvBuff[1024] = {0};    PROCESS_INFORMATION ProcessInformation;    sa.nLength=sizeof(sa);    sa.lpSecurityDescriptor=0;    sa.bInheritHandle=true;    if(!CreatePipe(&(this->m_hReadPipe1),&(this->m_hWritePipe1),&sa,0))    {        return FALSE;    }    if(!CreatePipe(&(this->m_hReadPipe2),&(this->m_hWritePipe2),&sa,0))    {        return FALSE;    }    ZeroMemory(&si,sizeof(si));    GetStartupInfo(&si);    si.dwFlags = STARTF_USESHOWWINDOW|STARTF_USESTDHANDLES;    si.wShowWindow = SW_HIDE;    si.hStdInput = this->m_hReadPipe2;    si.hStdOutput = si.hStdError = this->m_hWritePipe1;    GetSystemDirectory(cmdLine,sizeof(cmdLine));    _tcscat(cmdLine, _T("\\cmd.exe"));    if(CreateProcess(cmdLine,NULL,NULL,NULL,TRUE,0,NULL,NULL,&si,&ProcessInformation) == 0)    {        return FALSE;    }    return TRUE;}

发送命令到cmd.exe的代码：

BOOL CMotorolaSetDlg::SndCmdToPipe(CString csCmd){    BOOL bRet = FALSE;    unsigned long ulBytesRead = 0;    char* pcCmd = NULL;    pcCmd = CStringToChar(csCmd);    bRet = WriteFile(this->m_hWritePipe2, pcCmd,csCmd.GetLength()+1,&ulBytesRead,0);    if(pcCmd != NULL)    {        delete pcCmd;    }    return bRet;}

从cmd.exe接收反馈的代码：

BOOL CMotorolaSetDlg::RcvDataFromPipe(TCHAR* pwcBuff, DWORD dwLen){    BOOL bRet = FALSE;    unsigned long ulBytesRead = 0;        if(dwLen > sizeof(pwcBuff) && pwcBuff == NULL)    {        bRet = FALSE;    }    else    {        memset(pwcBuff, 0, dwLen);        bRet = PeekNamedPipe(this->m_hReadPipe1,pwcBuff,dwLen,&ulBytesRead,0,0);        if(bRet)            {            bRet = ReadFile(this->m_hReadPipe1,pwcBuff,dwLen,&ulBytesRead,0);        }        else        {            bRet = FALSE;        }    }    return bRet;}
