我正在关注Django网站上的教程来创建一个简单的民意调查应用程序.但是,Django无法解析"//127.0.0.1:8000/polls",即使我在mySite/urls.py中定义了正则表达式.我在virtualenv中这样做,安装了最新的Django(1.7).

MYSITE/urls.py:

from django.conf.urls import patterns, include, url
from django.contrib import admin

urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^polls/', include('polls.urls')),
)

MYSITE /调查/ urls.py:

from django.conf.urls import patterns, url
from polls import views

urlpatterns = patterns('',
url(r'^$', views.index, name='index'), 
)

MYSITE /调查/ views.py:

from django.shortcuts import render
from django.http import HttpResponse
def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")

MYSITE/settings.py:

 ...
 INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'polls',
 ) 
  ....
 ROOT_URLCONF = 'mySite.urls'

我得到的错误:

我是android app dev的新手.当我创建一个新的AVD时,当我点击这个AVD的开始:我得到以下内容:

Starting emulator for AVD 'Nexus_4_16_AVD'
PANIC: Could not open: Nexus_4_16_AVD

我正在编写一个简短的C#来解析给定的XML文件.但是其中一个标记值可以更改,但在where子句中始终包含单词"快速启动"(忽略大小写和空格,但需要按相同的顺序排列).我不确定如何在C#中的sql语句中执行此操作.

var selected = from cli in doc.Descendants(xmlns+ "Result")
     where cli.Element(xmlns + "ResultsLocation").Value == "Assessments-Fast-Startup"
                       select cli;

我是XML和C#的新手; 我正在尝试找到一种方法来有效地解析给定的xml文件以检索相关的数值,基于"proj_title"值= heat_run或任何其他可能的值.例如,计算特定测试运行的持续时间(proj_end val-proj_start val).

ex.xml:

<proj ID="2">
      <proj_title>heat_run</proj_title>
      <proj_start>100</proj_start>
      <proj_end>200</proj_end>
</proj>

...我们无法按项目ID进行搜索,因为此值不会从测试运行到测试运行.上面的文件很大:~8mb,并且有〜2000个标签,名称为proj_title.有没有一种有效的方法来首先找到所有标签名称w/proj_title ="heat_run",然后使用C#检索这个特定proj_title的proj开始和结束值？

这是我目前的C#代码:

public class parser
{
     public static void Main()
     {
         XmlDocument xmlDoc= new XmlDocument();
         xmlDoc.Load("ex.xml");

         //~2000 tags w/ proj_title
         //any more efficient way to just look for proj_title="heat_run" specifically?
         XmlNodeList heat_run_nodes=xmlDoc.GetElementsByTagName("proj_title");
     }
}    

我正在尝试使用Synaptics SDK在Synaptics触摸板上获取设备句柄,特别是使用SYNCTRLLib中的方法.但是,该SYNCTRL方法未能找到它,返回-1.

        int DeviceHandle;

        //Constructor
        public Syn ()
        {
            SynTP_API.Initialize();
            SynTP_API.Activate();

            //DeviceHandle == -1 ? Can't find device?
            DeviceHandle = SynTP_API.FindDevice(new SynConnectionType(), new SynDeviceType(), 0);
            //Below line causing Unhandled Exception
            SynTP_Dev.Select(DeviceHandle);
            SynTP_Dev.Activate();
            SynTP_Dev.OnPacket += SynTP_Dev_OnPacket;
        }

我在我的ASP .Net MVC Web App中使用了Hangfire,它已成功安装.我想使用相同的LocalDb来存储Hangfire的排队作业,以便像我以前用于存储数据一样出列和处理.但是我遇到下面的错误,当我提供了定义它的connectionString或名称Web.config中Startp.cs.我在添加时没有遇到任何麻烦,在hangfire之前删除了同一localDb中的更新数据.

Cannot attach the file 'c:\users\jerry_dev\documents\visual studio 2013\Projects\Hangfire.Highlighter\Hangfire.Highlighter\App_Data\aspnet-Hangfire.Highlighter-20150113085546.mdf' as database 'aspnet-Hangfire.Highlighter-20150113085546'.

Startup.cs:

public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
            app.UseHangfire(config =>
            {
                string hangfireConnectionString = @"Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\aspnet-Hangfire.Highlighter-20150113085546.mdf;Initial Catalog=aspnet-Hangfire.Highlighter-20150113085546;Integrated Security=True";
                config.UseSqlServerStorage(hangfireConnectionString);
                config.UseServer();
            });
        }

我的项目解决方案名为"Hangfire.Highlighter"

Web.config:

<connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\aspnet-Hangfire.Highlighter-20150113085546.mdf;Initial Catalog=aspnet-Hangfire.Highlighter-20150113085546;Integrated Security=True" providerName="System.Data.SqlClient" />

在Angular 2中,我想将1组中的2个单选按钮输入选项绑定到布尔类型的模型属性,但是我要么无法选择其中一个单选按钮,要么遇到另一个错误的绑定问题.我在我的HTML中尝试过以下内容.

我想将对话框片段中的用户类型字符串:"AddFriendDialogFragment.java"传回给调用它的活动:"HomeActivity.java".我通过在"AddFriendDialogFragment.java"中声明的接口执行此操作:"EditNameDialogListener".但是出于某种原因,HomeActivity没有看到这个界面,所以我得到一个"无法解析符号:"EditNameDialogListener"错误.
