webbrowser-control

问题 I'm building a powerpoint add-in that is going to be based around an embedded browser. For some reason, though, the standard shortcuts don't work. The WebBrowserShortcutsEnabled property is set to true (though I even got as far as trying setting it to false in case I was in backwards world). Stripping it down to the bare bones, my repro steps are: Create a new project, selecting the PowerPoint 2013 Add-in project type Add a new User Control to the project Add a WebBrowser to that control,

问题 I am hosting a web browser control, and want to provide my own context menu. Ideally, I want to present my own context menu, that contains the original browser's context menu (with all addins etc.) as a sub menu. If that's not possible / to tricky, I'd be ok with e.g. normally showing my context menu, and showing the original one when the user presses SHIFT. Do I need to implement IDocHostUIHandler? if yes, how do I specify a custom context menu, how can I force the original one? How do I get

问题 I have a Windows Forms application that uses a WebBrowser control to display an embedded web page. The file is (successfully) loaded using: webHelp.DocumentStream= Assembly.GetExecutingAssembly() .GetManifestResourceStream("MyAssembly.help.html"); In order for this to work (i.e. the file to be loaded/displayed) I set the webHelp.AllowNavigation = false; . I don't fully understand why, but if it's set to true, the page is not displayed. In my HTML document (see bellow) I want to be able to

问题 I have a WebBrowser inside a form and I want to do some automation with it. I click a button inside a windows form that commands the Navigate method of the WebBrowser to a certain page. Then I automatically click a link after DocumentCompleted has fired but after that I want to also click a Button that exists in the new page that appeared by clicking the link. It seems DocumentCompleted fires only when I click the button in the windows form not when I automatically click the a link inside the

问题 What's the best way to code in a wait for the browser to finish process before continuing? I tried this code below and the process is not waiting till its complete before processing the next link. void WaitBrowserLoading() { while (webBrowser1.IsBusy) Application.DoEvents(); for (int i = 0; i < 500; i++) if (webBrowser1.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); lblStoreID.Text = ""; //System.Threading.Thread.Sleep(5); } else break; Application.DoEvents(); } 回答1:

问题 I am using CefSharp v55.0 in my WinForm project. After the page is loaded, I want to get HTML code from it. And for that I am using this: private void WebBrowserFrameLoadEnded(object sender, FrameLoadEndEventArgs e) { if (e.Frame.IsMain) { test.ViewSource(); test.GetSourceAsync().ContinueWith(code => { var html = code.Result; }); } } And for the crosscheck, I am also calling test.ViewSource() method, to see that if GetSourceAsync method is getting the whole code or not. Unfortunetely, codes

问题 I am using the WebBrowser Control in C# in an application to display HTML. All the data comes from a database, so I am generating a full page with Inline-CSS in Memory and sending it to the browser. But now I want to support images, which seems to be a problem because I do not want to store the images on Hard drive, not even in a Temp Directory. I am aware of the data: URI Scheme, but that seems to be too limited. I wonder: Can I somehow use JavaScript to dynamically generate an image, given

问题 Can I figure out if a function has already been assigned to an event? e.g. (Standard winforms app with web browser control) namespace Crawler { public partial class Form1 : Form { WebCrawler.manager m; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { system.windows.forms.webbrowser wb = new system.windows.forms.webbrowser(); wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(foo); //[... Some other code ...] /* [Begin Example] */

问题 I'm looking for a free tool or dlls that I can use to write my own code in .NET to process some web requests. Let's say I have a URL with some query string parameters similar to http://www.example.com?param=1 and when I use it in a browser several redirects occur and eventually HTML is rendered that has a frameset and a frame's inner html contains a table with data that I need. I want to store this data in the external file in a CSV format. Obviously the data is different depending on the
