MFC隐藏线程窗口并把输出返回的方法

在MFC中如果要使用控制台指令,但并不希望弹出控制台窗口,并且可以获取控制台输出,可以用这个函数来实现




void RunCMD(TCHAR *pLog,TCHAR *pCmd)

{

    SECURITY_ATTRIBUTES sa;

    BOOL ret;

    sa.nLength=256;

    sa.lpSecurityDescriptor=0;

    sa.bInheritHandle=TRUE;

 

    HANDLE hReadPipe1,hWritePipe1,hReadPipe2,hWritePipe2;

 

    ret=CreatePipe(&hReadPipe1,&hWritePipe1,&sa,0);//创建两个匿名管道

    ret=CreatePipe(&hReadPipe2,&hWritePipe2,&sa,0);

 

    STARTUPINFO si;

    PROCESS_INFORMATION pi;

    ZeroMemory( &si,sizeof(si));

    si.cb = sizeof(si);

    si.dwFlags=STARTF_USESHOWWINDOW|STARTF_USESTDHANDLES;

    si.wShowWindow=SW_HIDE;

    si.hStdInput=hReadPipe2;

    si.hStdOutput=si.hStdError=hWritePipe1;

    ZeroMemory( &pi,sizeof(pi));

    unsigned long lBytesRead;

    char Buff[1024]={0};

    CString strLog;

 

    CreateProcess(NULL,pCmd,NULL,NULL,TRUE,0,NULL,NULL,&si,&pi);

    while(1)

    {

        ret=PeekNamedPipe(hReadPipe1,Buff,1024,&lBytesRead,0,0);//管道是否有数据可读

        if(lBytesRead&&pLog)

        {

             ret=ReadFile(hReadPipe1,Buff,lBytesRead,&lBytesRead,0);//读取管道里的数据

             if(!ret)

                 break;

             strLog.Format(_T("%S"),Buff);

             StrCpy(pLog,strLog.GetBuffer());

 

        }

        else

             break;

 

    }

// WaitForSingleObject( pi.hProcess, INFINITE );

    CloseHandle( pi.hProcess );

    CloseHandle( pi.hThread );

}

这样就可以隐藏调用控制台命令了
