问题 In my WinForm application, I have a "main" .net WebBrowser control with the following JS: var $hub; $(function () { $hub = $.connection.sendHub; $.connection.hub.stateChanged(connectionStateChanged); $.connection.hub.disconnected(function () { setTimeout(function () { $.connection.hub.start(); }, 10000); }); $hub.client.broadcastMessage = function (action, argument, tag) { // Do something }; $.connection.hub.start({ waitForPageLoad: false }).done(function () { }); function

问题 I checked. This question has not been asked yet. What is the WPF equivalant of DocumentCompleted for the WebBrowser class? the DocumentCompleted method does not exist in WPF (at least not in the latest version of .NET and visual studio). So how do I do the same thing that one could do with Windows Forms in WPF? 回答1: The event that you are looking for is LoadCompleted. Your can read more about it in .NET docs here http://msdn.microsoft.com/en-us/library/system.windows.controls.webbrowser

问题 I have a C# winform project with a webbrowser control. I'm loading an HTML page with images into the webbrowser. Each image has a different ID: <img src="F:\Temp\file12948.jpg" id="12948" width="180px"> Is there a way to pass the ID into a variable when clicking on the image so I can use the ID in my code? The path to the image can also be used as I can extract the number from there. I have already searched here there and everywhere for a solution but can't find anything related. 回答1: You can

问题 I have a webbrowser which is loading a website. If the website firing the "completed" event, my HTMLElementCollection shows me a count of "179". If I click on the button and call the same method to get all HTMLElements, it tells me a count of "194". The problem is: if the "completed"-Event is firing, some HTMLElements are not loaded, and needs a longer time, and my HTMLElement which I need to click on it, is missing too. To explain with code: private void Webbrowser_DocumentComplete(object
