小编Sha*_*512的帖子

出于某种原因,我无法使用附加到我想要使用的对象的函数.我在不起作用的行中添加了注释.作为一个错误,我得到"错误;不允许指向不完整类类型的指针"请帮助

这是dokter.ccp中的代码

int counter = 0;        
for (list<Wielrenner*>::iterator it = wielrenners.begin(); it != wielrenners.end(); it++){
    Wielrenner* wielrennerOB = *it;
    cout << "\nID: " << counter;
    cout << "List size: " << persons.size() << endl;

    wielrennerOB->print();  // This is not working
    counter++;
 }  

这是wielrenner.h中的代码

#ifndef WIELRENNER_H_

#define WIELRENNER_H_

//#include <fstream>

#include "persoon.h"

#include "Onderzoek.h"

class Wielrenner :
public Persoon
{
public:
    Wielrenner(string, string, Adres, string, Datum, Datum, string, int, float, float, float,list<Onderzoek>* );

我正在寻找一个使元素成为白色背景的类.

也许像.bg-white这样的东西,我在Bootstrap中找不到它但也许隐藏在某个地方？

我是码头工人的新手,并试图学习它.我遵循这个教程:https://docs.docker.com/get-started/part2/#apppy

所以我在Windows上安装了Docker.创建了3个文件,app.py,Dockefile和requirements.txt

我的docker文件看起来像这样

# Use an official Python runtime as a parent image
FROM python:2.7-slim

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
ADD . /app

# Install any needed packages specified in requirements.txt
RUN pip install --trusted-host pypi.python.org -r requirements.txt

# Make port 80 available to the world outside this container
EXPOSE 80

# Define environment variable
ENV NAME World
CMD ["python", "app.py"]

当我在powershell中运行它时 …

我将 social-auth-app-django 用于我的 django 网站。登录一切正常，但在令牌过期后。我不能再访问谷歌的用户数据了。我找到了如何刷新令牌，但它给出了

我试图弄清楚我需要在NTP请求包中发送(客户端)以从服务器检索NTP包.我正在使用Cortex M3上的LWIP,Stellaris LM3S6965

据我所知,我将接收UDP头,然后使用不同时间戳的NTP协议来消除延迟.我可能需要制作UDP标头,但我需要添加什么作为数据？

我试图通过html格式的输入字段传递数组.使用序列化传递它然后反序列化再次读取数组.我有多个输入字段.

$test = array('name' => 'Sander', 'type' => 'melon');

echo '<input type="hidden" name="rank[]" value="'.serialize($test).'" >';

然后,如果我想反序列化并显示数据,则会出错:

$list = $_POST['rank'];
var_dump($list);
var_dump(unserialize($list[0]));

data: {
            labels: ['29 Oct, 18', '30 Oct, 18', '02 Nov, 18', '14 Nov, 18', '15 Nov, 18', '19 Nov, 18', '20 Nov, 18', '28 Nov, 18'],
            datasets: [{
                pointRadius: 0,
                label: 'Positive',
                lineTension: 0,

我正在尝试更改折线图的颜色(Google可视化).多数民众赞成有效,但我找不到如何更改"猫"文字的颜色.

这里描述的是什么？https://developers.google.com/chart/interactive/docs/gallery/linechart

function drawVisualization() {
  // Create and populate the data table.
  var data = google.visualization.arrayToDataTable([

我目前正在为导航栏使用bootstrap,我已经改变了一些东西,所以它看起来不同.但我想将2个列表项对齐到ul的右侧.

我搜索过,但我找不到真正有效的解决方案.还要记住,我仍然希望导航栏能够完全响应.

<div class="navbar">
<div class="navbar-inner">
    <div class="container">

        <!-- .btn-navbar is used as the toggle for collapsed navbar content -->
        <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </a>

        <!-- Everything you want hidden at 940px or less, place within here -->
        <div class="nav-collapse collapse">
            <ul class="nav">
                <li class="active"><a href="#">Home</a></li>
                <li><a href="#">Video Library</a></li>
                <li><a href="#">Orphanages</a></li>
                <li><a href="#">The collective</a></li>
                <li><a href="#">What we do</a></li>
                <li><a href="#">Partners</a></li>
                <li class="donate"><a href="#">Donate</a></li>
           </ul>
        </div>
    </div>
</div>

我希望你们能帮助我弄清楚如何做到这一点.谢谢

我目前有这个代码,它检查数组中的所有元素是否相同.如果是这种情况,请返回true

def all_equal(lst):
  """
  >>> all_equal([1,1,1,1,1,1,1])
  True
  >>> all_equal([1,2,3,1])
  False
  """
  return len(frozenset(lst)) == 1

但我想要检查的是,是否至少有5个相同的元素.

以便

[1,1,1,1,1,2,2]

将返回True以及.因为有5次1
