问题 I am trying to embed a WebBrowser Control in a C# Winform Application. This sounds easy enough. However I discovered that the WebBrowser control eats up a lot of memory every time I call the Navigate method. The memory is never released. The memory usage grows and grows… Many people on the net having the exact same problem but I haven’t found a satisfying answer yet. This is the best discussions about this issue I found so far: Memory Leak in IE WebBrowser Control One person suggested an

问题 I\'m trying to create a program to clone multiple bugs at a time through the web interface of our defect tracking system. How can I wait before a page is completely loaded before I continue? //This is pseudo code, but this should give you an idea of what I\'m trying to do. The //actual code uses multi-threading and all that good stuff :). foreach (string bug in bugs) { webBrowser.Navigate(new Uri(url)); webBrowser.Document.GetElementById(\"product\").SetAttribute(\"value\", product);

问题 I\'m using the Winforms WebBrowser control to collect the links of video clips from the site linked below. LINK But, when I scroll element by element, I cannot find the <video> tag. void webBrowser_DocumentCompleted_2(object sender, WebBrowserDocumentCompletedEventArgs e) { try { HtmlElementCollection pTags = browser.Document.GetElementsByTagName(\"video\"); int i = 1; foreach (HtmlElement link in links) { if (link.Children[0].GetAttribute(\"className\") == \"vjs-poster\") { try { i++; }

问题 I have a c# .Net application that opens a custom Print Preview form (compromising of a WebBrowser form control that displays a HTML file and a button which prints the contents of the web browser control: webBrowser.Print(); However, I now would like to print the HTML file WITHOUT opening this form. I have tried to load the html into a webbrowser form without displaying the form and called webBrowser.Print() but nothing will print. It seems I only can print if I show the form and load the HTML

问题 I\'m using the WebBrowser control in Visual Studio 2010 and trying to display the page: http://lk21.org. Inside that webpage there are lots of scripts loaded, and it works fine if I open it through a web browser such as Firefox, Chrome, and the latest version of IE. My question is, why does it display \"Bad Request\" when I tried using the WebBrowser component to navigate to that page? Check this out: UPDATE: The page loads nicely using Visual Vincent\'s answer. However the flash videos on

问题 This is a widely-known, old issue with the .NET Webbrowser control. Summary: Having the .NET webbrowser control Navigate to a page increases memory usage that is never freed. Reproduce the memory leak: Add a WebBrowser control to a form. Use it to Navigate to whatever pages you\'d like. about:blank works, scrolling down on Google Images until your usage is 100MB+ and then browsing elsewhere to notice barely any of that memory is freed is a more dramatic demonstration. My current requirements

问题 I am trying to capture the content of the WebBrowser control. DrawToBitmap() would work perfectly, but it is not supported in documentation for the WebBrowser control. I have been trying to find another way to capture the contents of the WebBrowser control and save them to a local image file. Does anyone have any workarounds or other methods to save the contents of the WebBrowser control to a local image file? 回答1: The Control.DrawToBitmap doesn't always work so I resorted to the following

问题 I am using the WebBrowser control in my VB.NET application to load a few URLs ( ~10-15) and save their HTML source in a text file. However, my code doesn\'t write the source of the current page rather the initial one because the it is triggered even before the page is loaded. How can I wait until the page is completely loaded before calling any event? I tried the following code but it doesn\'t work. Do Until WebBrowser1.ReadyState = WebBrowserReadyState.Complete Application.DoEvents() Loop

问题 In my WinForms app, if I use a WebBrowser control, it seems to be forced into compatibility mode. How can I disable this, and make it behave the same as standalone IE does on my machine when browsing the same site? I do not want to make registry changes. I want everything to be contained within my app. The website I\'m loading is not mine, so I do not have the ability to make changes to it (unless they can be done programmatically from within my app). 回答1: There is no way to do this other

问题 I\'m working on a web application for which I\'m attempting to implement a full featured windowing system. Right now it\'s going very well, I\'m only running into one minor issue. Sometimes when I go to drag a part of my application (most often the corner div of my window, which is supposed to trigger a resize operation) the web browser gets clever and thinks I mean to drag and drop something. End result, my action gets put on hold while the browser does its drag and drop thing. Is there an
