webbrowser-control

问题 I have a simple WPF webBrowser control that I am using to automate a website. The page that I'm trying to load is an ASP.NET page. When I try to navigate to it normally, LoadCompleted is never fired. If I try to navigate to it, and read the elements with an IHTMLElementCollection in the Navigated event, then the LoadCompleted event does fire. It doesn't make sense to me. The LoadCompleted event should fire regardless, because I'm loading a page in both situations. Any ideas? 回答1: It turns out

问题 I'm using the IWebBrowser2 interface to render a page from an HTML string created at runtime. I have written a method (let's call it DisplayHtmlString) that takes an HTML string and renders it as shown in this example. The method also calls Navigate2 with "about:blank" first, to ensure a document is present, and it also calls close after calling write. The first time I call DisplayHtmlString, the page is always rendered correctly, i.e. the browser displays HTML according to the string I pass.

问题 How can I put, and use, a progress bar for my web browser control, in a windows application project, using the c# language? 回答1: Look at the WebBrowser.ProgressChanged event. 回答2: The WebBrowser control has a ProgressChanged event: You need to attach an event handler to the ProgressChanged event: WebBrowser1.ProgressChanged += WebBrowser1_ProgressChanged; This is shorthand for: WebBrowser1.ProgressChanged += new WebBrowserProgressChangedEventHandler(WebBrowser1_ProgressChanged); The compiler

问题 Is there a way to disable pinch and zoom on a WPF WebBrowser Control. The enviroment is a win8 Desktop WPF app using .NET4.0. With a regedit setting that tells it to use IE10 engine.

问题 In a WP7 Silverlight application with a WebBrowser control I want to use an own protocol like "myttp://" to deliver some local content. I can't use Navigate() to an IsolatedStrorage because some content will by created on demand. For the same reason NavigateToString() is also not usable for me.
