I want to read network folder of my users. Users network folder information is stored in database. For example, \\\\192.168.3.107\\Network is one of my user network folder. As a user, I have made one of my folder Network as Network folder and my IP is 192.168.3.107. Now I want to read all of file inside that network file. I already done this in windows. But I need to implement this on Ubuntu. My code is given below:

如何在多维数组中分配字符串值,将数组作为函数参数发送,并将其返回给main函数？我试过这个,但它给出了一个错误:

char a[250][250][250];   // does not work
a[][0][2] = "0";         // does not work
a[][1][2] = "0";         // does not work

char a[][2][2] = {"0", "1"};  // works

// error: expected primary-expression before ']' token
a[i][j][max] = add_func(a[i][j][], i, j); 

我是CodeIgniter的新手并使用CodeIgniter_2.1.3.我正在关注NETTUTS CodeIgniter教程.我想开发一个带有codeIgniter的登录系统,它在没有md5()函数的情况下运行良好[ 没有加密密码 ].然后我使用md5()函数创建带有加密密码的新表.然后登录代码不起作用.我的代码是::

视图/ login_form.php

<?php   
      // form design       

     echo form_open("login/validate") . "<br/>";    
     echo form_input("username", "Username") . "<br/> <br/>";
     echo form_password("password", "password") . "<br/> <br/>";
     echo form_submit("submit", "Login") . "<Br/> <Br/>";

     echo anchor("login/sign_up", "Create Account"); 

 ?>

控制器/ login.php中

 <?php
     class Login extends CI_Controller {

        function index() {   // function of loading login page
           $data['main_content'] = "login_form";   // name of login page

           $this->load->view("includes/templet", $data);  
        }

    function validate() { …

我是node.js,mongodb,express的新手,在设置数据库方面遇到了很多麻烦.我的代码(app.js)如下

var express = require('express'),
    app = express(),
    cons = require('consolidate'),
    MongoClient = require('mongodb').MongoClient,
    Server = require('mongodb').Server;

    app.engine('html', cons.swig);
    app.set('view engine', 'html');
    app.set('views', __dirname + '/views');

var mongoclient = new MongoClient(new Server("localhost", 27017));
// error occurs here
var db = mongoclient.db('course');

app.get('/', function(req, res){  
   // Find one document in our collection
   db.collection('hello_combined').findOne({}, function(err, doc) {
      if(err) throw err;
      res.render('hello', doc);
   });
});

mongoclient.open(function(err, mongoclient) {
   if(err) throw err;
   app.listen(8080);
});

当我运行此代码节点app.js时,我有以下错误:

我试图发送html如json在http post request.但是当我试图提出$http.post请求时,我遇到了以下错误:

angular.js:12783 SyntaxError: Unexpected token I in JSON at position 0
    at Object.parse (native)
    at fromJson (http://localhost:9001/bower_components/angular/angular.js:1274:14)

    at Scope.$eval (http://localhost:9001/bower_components/angular/angular.js:16359:28)

我的代码(角度)如下:

  $scope.generate_pdf = function() {
    var html =  angular.element('html').html(); // get all html

    var service = API.getService();
    // JSON.stringify( { html:  html } this also cause same error
    service.downloadPdf({}, { html: …

在我的dynamoDB中，我有一个表，其结构如下所示：

 var params = {
      "TableName" : "pdfs",
      "Item" : {
          pdfid:  // Partition key
          html: [] // array attribute
       }
 };

我可以插入新的数组数据，就像给定的代码一样：

插入数组数据

 var params = {
      "TableName" : "pdfs",
      "Item" : {
          pdfid: pdfid,
          html: [event.html]   // here "html" is an array, I just insert first array data
       }
 };

 dc.put(params, function(err, data) {
     ............................
 });

如何更新数组dynamoDB？

  var params = {
      TableName: "pdfs",
      Key: {
         pdfid: event.pdfid
      },
      UpdateExpression: "SET html = :html",
      ExpressionAttributeValues: …
