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;
}
