If you don’t want to modify the registry and you control the webpage, you can use the <meta http-equiv=”X-UA-Compatible” content=”IE=10″> tag in the document’s head. I believe it has to be first or immediately following <title> in order to work.
Right idea, wrong execution. The WebBrowser.Navigate() only tells the web browser to start navigating to the web page you asked for. That takes time, hundreds of milliseconds typically. Internet Explorer internally starts threads to get the job done. It tells you when it is done by raising the DocumentCompleted event. You don’t wait for that … Read more
Let me tell you some disadvantages… [most of the problems mentioned here has been answered or addressed to some degree in my previous answers section in StackOverflow, if you are curious, feel free to browse my WebBrowser-Control related answers]. Detecting when page is really done loading is very difficult to do reliably, in fact, you … Read more
IMO, what you’re trying to do is indeed a legit scenario for UI testing automation. IIRC, in early versions of IE it was possible to populate the <input type=”file”/> field with a file name, without showing up the Choose File dialog. For security reason, this is no longer possible, so you have to send keys … Read more
You have to implement an async pluggable protocol, e.g. IClassFactory, IInternetProtocol… Then you use CoInternetGetSession to register your protocol. When IE calls your implementation, you can serve your image data from memory/provide mime type. It’s a bit tedious, but doable. Look at IInternetProtocol and pluggable protocols documentation on MSDN.
Assuming that you have no need for floating point exceptions to be unmasked in your application code, far and away the simplest thing to do is to mask exceptions at some point in your initialization code. The best way to do this is as so: SetExceptionMask(exAllArithmeticExceptions); This will set the 8087 control word on 32 … Read more
There is nothing built-in in the WebBrowser control to retrieve an element by class name. Since you know it is going to be an a element the best you can do is get all a elements and search for the one you want: var links = webBrowser1.Document.GetElementsByTagName(“a”); foreach (HtmlElement link in links) { if (link.GetAttribute(“className”) … Read more
Add a SaveFileDialog control to your form, then add the following code on your WebBrowser’s Navigating event: private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e) { if (e.Url.Segments[e.Url.Segments.Length – 1].EndsWith(“.pdf”)) { e.Cancel = true; string filepath = null; saveFileDialog1.FileName = e.Url.Segments[e.Url.Segments.Length – 1]; if (saveFileDialog1.ShowDialog() == DialogResult.OK) { filepath = saveFileDialog1.FileName; WebClient client = new WebClient(); client.DownloadFileCompleted … Read more
If you don’t want to use the registry key technique, you could insert the following tag: <meta http-equiv=”X-UA-Compatible” content=”IE=8″ /> The “content” attribute forces rendering in various modes.
What I would do is assign an object to webbrowser.ObjectForScripting and then inject a javascript function that assigns windown.onerror to a wrapper that calls the external script in the host app. Like: window.onerror = function(message, url, lineNumber) { window.external.errorHandler(message, url, lineNumber); } Refere to: http://notions.okuda.ca/2009/06/11/calling-javascript-in-a-webbrowser-control-from-c/
