是否有任何图书馆或课程在那里展示360度全景iPhone？

我在这里找到了这个:http://code.google.com/p/panoramagl/ 但它不是最新的,只适用于旧版本的ios.

我很感谢任何帮助我在ios上创建360度全景视图的链接.

我有一台西门子1200 PLC.使用node-opcua客户端和Kepserver我能够读取变量并更改值.现在我想在KepServer中从node-opcua在PLC中创建一个新变量.

我曾尝试使用node-opcua服务器,因为在示例中我已经看到了如何创建变量,但是我收到错误,因为我正在尝试连接到KepServer所执行的相同端口.

var server = new opcua.OPCUAServer({
    port: 49320, // the port of the listening socket of the server
    resourcePath: "", // this path will be added to the endpoint resource name
     buildInfo : {
        productName: "MySampleServer1",
        buildNumber: "7658",
        buildDate: new Date(2014,5,2)
    }
});

我怎么处理创建一个新变量？并从node-opcua创建一个组标签？

是否可以在Kepserver中安装opcua服务器并创建直接连接到该服务器的变量？我的Kepserver位于:opc.tcp:// localhost:49320要连接到此Kepserver,我使用nodeopcua客户端:

var opcua = require("node-opcua");
var client = new opcua.OPCUAClient();
var endpointUrl = "opc.tcp://127.0.0.1:49320";
var the_session = null;
async.series([


    // step 1 : connect to
    function(callback)  {

        client.connect(endpointUrl,function (err) {

            if(err) …

我有一个计算的算法percentile(85)与Apache Commons一系列值(12个值)与阈值,为以后的评估作出决定.结果类似于Excel给出的结果,但不相等,有时这对我的应用程序至关重要,因为使用excel时结果不会超过阈值,并且使用Apache Commons Math Java,所以我获得了不同的输出.

这是一个例子:互联网流量(Mbps)每2小时

32,7076813360000000 41,2580429776000000 45,4453940200000000 48,8044409456000000 46,7462847936000000 49,8028100056000000 54,3719451144000000 41,9708134600000000 29,4371963240000000 22,4667255616000000 20,0388452248000000 28,7807757104000000

除以1000 Mb(电缆的容量)后,我计算职业的百分位数(85):

Excel:0,049153870117

Apache Commons Math:0.05003126676104001

我发现有可能改变百分位的实现(它不存在官方的)setPercentileImpl(),但我找不到任何如何做到的例子,或Excel算法(我是那个告诉实现).

对此有任何帮助都会受到欢迎.

谢谢.

我正在尝试使用图像和菜单链接进行引导菜单,当它滚动时,菜单会粘在窗口的顶部.

我找到了有趣的bootstrap词缀,并使用了这个帖子中的内容: bootstrap-affix:Div下面的词缀"跳转"到顶部.如何让它顺利滚动？

问题是当我按下菜单按钮时,选项位于页面的内容文本下.

我写了一个小提琴,让你看到我的问题并尝试解决方案:http: //jsfiddle.net/mram888/WnPqF/

我试图为菜单div的类添加不同的z-index,但只有在页面滚动并且菜单贴在顶部时才能正常工作.

#nav.affix {
    position: fixed;
    top: 0;
    width: 100%;
    z-index:2;
}

#nav > .navbar-inner {
    border-left: 0;
    border-right: 0;
    border-radius: 0;
    -webkit-border-radius: 0;
    -moz-border-radius: 0;
    -o-border-radius: 0;
}

.nav-wrapper {
    z-index: 2;
}

早上好.

我在linux上,使用cocos2d-x Android.

我创建了一个计算圆值的函数.

        // Circle point updateCircle()
    // x = number of iteration · SamplingPeriod   |-|-|-|
    // y = A · sine ( 2 · PI · number of iteration · SamplingPeriod / Period )
    int iterations = this->getNumberOfIterations();
    CCPoint centerPoint = this->getCenter();
    float x = centerPoint.x + this->getAmplitude() * cos( 2 * M_PI * iterations * this->getSamplingPeriod() * this->getFrequency() );
    float y = centerPoint.y + this->getAmplitude() * sin( 2 * M_PI …

我实际上在Linux上工作,但我也使用Mac.

我正在尝试为我的游戏添加多语言支持,并且我将使用不同的XML和标签.

当我使用ccLanguageType _myLanguage = CCApplication::getCurrentLanguage()get null时,信号11异常.

我也用过getCurrentLanguageJNI() 但是没用.

这是怎么回事？

按照本指南自定义数据库表的自定义模块,我是magento的新手

我已经将我已经存在的模块实现到后端adminhtml.我正在从数据库中获取内容并在adminhtml页面上播放.一切正常,除了我在adminhtml上获得两次网格​​.我两次得到同一个网格.我已经看了2个小时的代码无法搞清楚.如果有人知道如何解决这个问题,我会非常愚蠢.干杯

这就是我的grid.php中的代码

<?php

      class Ecom_Pricenotify_Block_Adminhtml_Pricenotify_Grid extends Mage_Adminhtml_Block_Widget_Grid{
public function __construct()
{
    parent::__construct();
    $this->setId('pricenotifyGrid');
    // This is the primary key of the database
    $this->setDefaultSort('pricenotify_id');
    $this->setDefaultDir('ASC');
    $this->setSaveParametersInSession(true);
}

protected function _prepareCollection()
{
    $collection = Mage::getModel('pricenotify/pricenotify')->getCollection();
    $this->setCollection($collection);
    return parent::_prepareCollection();
}

protected function _prepareColumns()
{
    $this->addColumn('pricenotify_id', array(
        'header'    => Mage::helper('pricenotify')->__('Notification ID'),
        'align'     =>'left',
        'width'     => '50px',
        'index'     => 'pricenotify_id',
    ));

    $this->addColumn('prod_id', array(
        'header'    => Mage::helper('pricenotify')->__('Product ID'),
        'align'     =>'left',
        'width'     => '50px',
        'index'     => 'prod_id',
    ));


    $this->addColumn('prod_price', array(

我正在使用PhoneBap的StatusBarNotification插件(Android)来发送通知.现在我想在特定的时间到这个,从我读过的,我必须使用Android的AlarmManager.我已经尝试了一些方法,但似乎无法让它工作.

有关如何做到这一点的任何建议？

编辑:我可以得到通知,以显示我是否将代码放在onReceive()中showNotification().问题似乎是接收器没有收到Alarm-thingy.可能是因为我在IntentFilter中没有正确的操作.

这是我的代码.我从Phonegap的StatusBarNotification插件构建它,在这里找到

public class StatusBarNotification extends Plugin {
//  Action to execute
public static final String ACTION="notify";

private Context context;
BroadcastReceiver receiver;

public StatusBarNotification() {
    this.receiver = null;
}

public void setContext(PhonegapActivity ctx) {
    super.setContext(ctx);
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction(); //Dunno what to put here
    if(receiver == null) {
        this.receiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                Log.d("Notification", "inside onReceive");
                /*int icon = R.drawable.notification;
                long when = System.currentTimeMillis();
                NotificationManager manager …

好的，我本以为这是一个简单的问题，但是显然这让我感到困惑。

当我尝试设置RibbonComboBox的高度时，它并没有移动它的实际大小，只是围绕它的盒子移动。

这是我的XAML：

<ribbon:RibbonComboBox                                                           
    DisplayMemberPath="CompanyCode" 
    Height="22" 
    Margin="0,0,0,-30" 
    VerticalAlignment="Bottom" 
    Width="102">
  <ribbon:RibbonGallery SelectedValue="{Binding Path=Companies.SelectedItem,
                                                ValidatesOnDataErrors=true,
                                                NotifyOnValidationError=true }">
    <ribbon:RibbonGalleryCategory ItemsSource="{Binding Path=Companies.Items, 
                                                        NotifyOnValidationError=true, 
                                                        ValidatesOnDataErrors=true}" />
  </ribbon:RibbonGallery>
</ribbon:RibbonComboBox>

我可以将高度更改为200或1，但是高度永远不会改变。

我究竟做错了什么？

谢谢，埃罗克
