Best way to implement keyboard shortcuts in a Windows Forms application?

I'm looking for a best way to implement common Windows keyboard shortcuts (for example Ctrl+F, Ctrl+N) in my Windows Forms application in C#. The application has a main form which hosts many child forms (one at a time). When a user hits Ctrl+F, I'd like to show a custom search form. The search form would depend on the current open child form in the application. I was thinking of usi

在Windows窗体应用程序中实现键盘快捷方式的最佳方法?

我正在寻找一种在我的Windows Forms应用程序中用C#实现常用Windows键盘快捷键(例如Ctrl + F,Ctrl + N)的最佳方式。 该应用程序有一个主表单,它容纳许多子表单(一次一个)。 当用户点击Ctrl + F时,我想显示一个自定义搜索表单。 搜索表单将取决于应用程序中当前打开的子表单。 我正在考虑在ChildForm_KeyDown事件中使用这样的事情: if (e.KeyCode == Keys.F && Control.ModifierKeys == Keys.Control)

HTTPWebRequest Cookie different behaviour

I'm developing an application that needs to login into a website, www.example.com, using the class HTTPWebRequest and a CookieJar to handle Cookies. The problem I have is that on some computers, the procedure works just fine, but on some others ( with a 1-1 ratio) it doesn't, with no SO/IE version pattern whatsoever. I've tried logging every single GET and POST request, and here i

HTTPWebRequest Cookie的行为不同

我正在开发一个应用程序,需要使用类HTTPWebRequest和一个CookieJar来处理Cookie,并需要登录到网站www.example.com。 我遇到的问题是,在某些计算机上,该程序运行得很好,但在其他一些计算机上(比率为1比1)却没有,没有SO / IE版本模式。 我试过记录每一个GET和POST请求,这里是问题: 工作要求 内容类型:application / x-www-form-urlencoded 用户代理:Mozilla / 5.0(Windows NT 6.1; WOW64; rv:19.0)Gecko

SignlaR not working with load balancing

We already had a server with signalr hub where clients connect using signalr. We recently moved it to two nodes with a load balancer for scalability. But after moving it to load balancer now clients are unable to connect to the server using signalr. Clients first try using web sockets and it gives the following error on signalr trace. fae26beb-a806-4957-b52a-39b80856e492 - Auto: Failed to

SignlaR不支持负载平衡

我们已经有一个服务器与信号中心客户端连接使用信号。 我们最近将其移至具有负载平衡器的两个节点以实现可伸缩性。 但是在将其移动到负载均衡器后,客户端无法使用信号连接到服务器。 客户首先尝试使用网络套接字,并在信号跟踪上给出以下错误。 fae26beb-a806-4957-b52a-39b80856e492 - Auto: Failed to connect to using transport webSockets. System.Net.WebSockets.WebSocketException (0x80004005): Unable to conne

How to find the first item according to a specific ordering using LINQ in O(n)?

Suppose I have a list of items (eg, Posts) and I want to find the first item according to some non-trivial ordering (eg, PublishDate and then CommentsCount as a tie-breaker). The natural way to do this with LINQ is like this: posts.OrderBy(post => post.PublishDate).ThenBy(post => post.CommentsCount).First() However, the micro-optimizer in me is worried that calling OrderBy actually costs

如何根据O(n)中使用LINQ的特定顺序找到第一个项目?

假设我有一个项目列表(例如,帖子),并且我想根据一些非平凡的顺序(例如,PublishDate然后评论计数作为决胜因子)找到第一个项目。 用LINQ做这件事的自然方式是这样的: posts.OrderBy(post => post.PublishDate).ThenBy(post => post.CommentsCount).First() 然而,我的微优化器担心的是,调用OrderBy实际上花费我O(n * lgn)来排序整个列表,当我真正需要的是O(n)find-minimum操作时。 那么,LINQ智能够从Ord

Is there a way to use a custom control in the designer and avoid the GAC?

There is a great library I found here. It's AeroWizard done in Windows Forms, and it handles Aero Basic elegantly. What is awesome is it's supposed to have designer support. When I attempt to open any of the WizardPages in the sample in the Form Designer, I get this error: Could not find type 'Aero.Controls.MainInstructionsLabel'. Please make sure that the assembly that conta

有没有办法在设计器中使用自定义控件并避免使用GAC?

我在这里找到了一个很棒的图书馆。 它是在Windows Forms中完成的AeroWizard,它优雅地处理Aero Basic。 真棒是它应该有设计师的支持。 当我尝试在窗体设计器中打开示例中的任何WizardPages时,出现此错误: Could not find type 'Aero.Controls.MainInstructionsLabel'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure

MVC Core, Web Sockets and threading

I am working on a solution that uses web socket protocol to notify client (web browser) when some event happened on the server (MVC Core web app). I use Microsoft.AspNetCore.WebSockets nuget. Here is my client-side code: $(function () { var socket = new WebSocket("ws://localhost:61019/data/openSocket"); socket.onopen = function () { $(".socket-status").css("color", "green");

MVC核心,Web套接字和线程

我正在研究一个解决方案,该解决方案使用Web套接字协议在服务器(MVC Core Web应用程序)发生某些事件时通知客户端(Web浏览器)。 我使用Microsoft.AspNetCore.WebSockets nuget。 这是我的客户端代码: $(function () { var socket = new WebSocket("ws://localhost:61019/data/openSocket"); socket.onopen = function () { $(".socket-status").css("color", "green"); } socket.onmessage = f

HTML5 Web socket Handshaking

I'm sort of new to web programming, but I wanted to write a HTML interface for a embedded device (coded in C) that I am developing. I've already implemented a stream server (a la beej's socket server example) and a java client, but I'm interested in implementing a HTML5 Socket interface instead. I am having some trouble with the handshaking (in so much as the server accepts the

HTML5 Web套接字握手

我对网络编程有点陌生,但我想为我正在开发的嵌入式设备编写一个HTML接口(用C编码)。 我已经实现了一个流服务器(一个beej的套接字服务器示例)和一个java客户端,但我有兴趣实现一个HTML5套接字接口。 我在握手方面遇到了一些麻烦(尽管服务器接受连接但网页没有),并且想知道是否有可用的规范在线。 w3c规范似乎只描述了API(据我所知)而不是握手的细节。 我不是在寻找一个完整的书面例子(我可以做到这一点!)只是

wpf listview selecteditem oneway binding

I have a thin client UI. This UI must always reflect the remote server values. This UI has a listview that must have a OneWay binding. Clicking on an item does NOT select it. Double-clicking triggers an event that activates the item on the remote server, which will update a value in the viewmodel indicating that this item is the active item. The listview needs to display this "active&qu

wpf listview selecteditem单向绑定

我有一个瘦客户端用户界面。 此用户界面必须始终反映远程服务器值。 此用户界面有一个必须具有OneWay绑定的列表视图。 点击一个项目不会选择它。 双击会触发激活远程服务器上的项目的事件,该事件将更新视图模型中指示该项目是活动项目的值。 该列表视图需要显示此“活动”状态,所以我将SelectedItem绑定到此ViewModel属性OneWay。 这里是我使用的XAML: <ListView ItemsSource="{Binding Songs}" SelectedItem="

How can I mark a `DependencyProperty` as `BindsTwoWayByDefault` in UWP?

In WPF you could mark a DependencyProperty on a custom control as binding Mode=TwoWay by default using FrameworkPropertyMetadataOptions.BindsTwoWayByDefault , but FrameworkPropertyMetadata seems to be missing in UWP. The UWP documentation on the {Binding} markup extension says that the default mode may change, but gives no indication on how to affect it. Mode Specifies the binding mode, as o

如何在UWP中将`DependencyProperty`标记为`BindsTwoWayByDefault`?

在WPF中,您可以将自定义控件上的DependencyProperty标记为绑定Mode=TwoWay ,默认情况下使用FrameworkPropertyMetadataOptions.BindsTwoWayByDefault ,但FrameworkPropertyMetadata似乎在UWP中缺失。 关于{Binding}标记扩展的UWP文档指出,默认模式可能会更改,但不会指示如何影响它。 模式 指定绑定模式,作为以下值之一:“OneTime”,“OneWay”或“TwoWay”。 这些对应于BindingMode枚举的常量名称。 默认取决于绑定目标

Bind flag enums to a control and back to the enum property

I've a telerik RadAutoCompleteBox to show / select enum flags and a converter for the binding. But it works only to bind to the target not back to the property. The ConvertBack method just isn't called. WPF: <telerik:RadAutoCompleteBox x:Name="RadAutoCompleteBox" FilteringBehavior="{StaticResource EmptyTextFilteringBehavior}" ItemsSource="{Binding Source={local:EnumBindingSource {

将标志枚举绑定到控件并返回枚举属性

我有一个telerik RadAutoCompleteBox来显示/选择枚举标志和转换器的绑定。 但它只适用于绑定到目标而不是回到属性。 ConvertBack方法只是不被调用。 WPF: <telerik:RadAutoCompleteBox x:Name="RadAutoCompleteBox" FilteringBehavior="{StaticResource EmptyTextFilteringBehavior}" ItemsSource="{Binding Source={local:EnumBindingSource {x:Type model:FlagEnum}}}" SelectedItems="{Binding Entity.FlagEnum, Mode
