我发现当我点击ScrollViewer时,PointerPressed和PointerExited事件会按预期触发.但是,如果我在触摸屏幕后向任何方向滚动并抬起我的手指,除了PointerCaptureLost之外没有任何事件会发生火灾,只要我滚动它就会过早地触发.

当我捕获指针ID并使用计时器轮询PointerPoint的状态时,即使在我滚动后抬起手指,IsInContact标志仍然为真.当我点击屏幕时,它按预期工作.

ManipulationCompleted具有与上面相同的效果,我无法使用ViewChanged事件,因为在我抬起手指之前会触发它.

这是一个错误还是我错过了什么？当用户将手指从屏幕上抬起时,我还能检测到另一种方法吗？这让我开始香蕉.

示例代码如下.您需要在触摸模式下使用模拟器或具有可触摸屏幕进行测试:

代码:

using System;
using Windows.UI.Input;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Input;

namespace App1
{
    public sealed partial class MainPage : Page
    {

        private readonly DispatcherTimer pointerTimer = new DispatcherTimer();
        private uint? CurrentPointerID; //container for the current pointer id when user makes contact with the screeen

        public MainPage()
        {
            this.InitializeComponent();

            scrollviewer.PointerPressed += scrollviewer_PointerPressed;
            scrollviewer.PointerMoved += scrollviewer_PointerMoved;
            scrollviewer.PointerExited += scrollviewer_PointerExited;
            scrollviewer.PointerReleased += scrollviewer_PointerReleased;
            scrollviewer.PointerCaptureLost += scrollviewer_PointerCaptureLost;
            scrollviewer.PointerCanceled += scrollviewer_PointerCanceled;


            pointerTimer.Tick += pointerTimer_Tick;
            pointerTimer.Interval = TimeSpan.FromMilliseconds(300);
            pointerTimer.Start(); …

好的,所以我曾经能够在项目属性对话框中更改SSL端口号,但在asp.net 5 RC1更新之后,SSL字段是只读的:

当我尝试直接编辑.xproj时,它会忽略SSLPort值:

<PropertyGroup>
    <SchemaVersion>2.0</SchemaVersion>
    <DevelopmentServerPort>17204</DevelopmentServerPort>
    <SSLPort>44303</SSLPort>
  </PropertyGroup>

当我更改绑定并启动我的项目时,它还会将我的应用程序主机配置文件($ [solutionDir] .vs\config\applicationhost.config)中的端口重置为原始值.

        <site name="WebApplication1" id="8">
            <application path="/" applicationPool="Clr4IntegratedAppPool">
                <virtualDirectory path="/" physicalPath="C:\WebApplication1\wwwroot" />
            </application>
            <bindings>
                <binding protocol="http" bindingInformation="*:17833:localhost" />
                <binding protocol="https" bindingInformation="*:44303:localhost" />
            </bindings>
        </site>

是什么赋予了？Visual Studio从哪里获取此值,以及如何更改它？

所以我有一个简单的Signalr/Knockout项目,它使用映射插件将一个简单的对象(带有更多项的数组的项)绑定到我在JS中定义的viewModel:

var someObjectMapping = {
    'MyItemArray': {
        create: function (options) {
            return new MyItemViewModel(options.data);
        }
    }
}

var myItemMapping = {
    'ItemChildren': {
        create: function (options) {
            return new ItemChildViewModel(options.data);
        }
    }
}

var SomeObjectViewModel = function (data) {
    ko.mapping.fromJS(data, someObjectMapping, this);
}

var MyItemViewModel = function (data) {
    ko.mapping.fromJS(data, myItemMapping, this);
}

var ItemChildViewModel = function (data) {
    ko.mapping.fromJS(data, null, this);
}

我使用SignalR的默认设置连接到我的集线器,如下所示:

    var myHubProxy = $.connection.myHub;

    myHubProxy.client.processSomeObject = function(someObject) {
        console.log('SomeObject received');
        var viewModel = new SomeObjectViewModel(someObject);
        ko.applyBindings(viewModel); …

我想在连续的Azure Web作业中使用SignalR自托管项目.但是当我尝试运行它时,我收到以下错误:

[07/11/2014 10:58:44 > cbec50: SYS INFO] Status changed to Running
[07/11/2014 10:58:45 > cbec50: ERR ] Unhandled Exception: System.Reflection.TargetInvocationException: 
Exception has been thrown by the target of an invocation. ---> System.Net.HttpListenerException: Access is denied

我想控制台应用程序需要以提升的权限运行.有没有办法让这个工作？

先决条件:

Install-Package Microsoft.Azure.Jobs -pre
Install-Package Microsoft.AspNet.SignalR.SelfHost
