webbrowser-control

问题 I have a component that uses the old WebBrowser control. The problem is that i use it to automate a process accessing a thirdy party page. The problem is that now i need to get a image, and this image is loaded by an extra GET request that i dont have control. For example, i make a: webBrowser.Navigate("example.com"); And on the DocumentCompleted event i do some stuff. But when this event is fired, i see on fiddler that the browser make to extra GETs one to load a token and other to load a

问题 I have this code: private void goButton_Click(object sender, EventArgs e) { web.Navigate(loginURL.Text + "/auth/login"); } I have the browser showing, and it's just not navigating...

问题 I have for plus 10 hours now tried to get a hole through to the WebBrowser property. I am simply trying to navigate to google.com and print the html code to the console. This constantly gives me a null reference. There is alot of questions related to this and they all say that a DocumentCompleted Eventhandler is needed or not setup properly. So i tried this to the best of my ability though still no luck. I then went so far as to copy paste the official example from Microsoft I am still

问题 Now before posting this question i did read... How to select a class by GetElementByClass and click on it programmically But this doesn't work for me. Apparently I'm an idiot and don't know how to use that code, or its just not working for me. I also am using the WebBrowser Control in VB.NET if that helps at all... I have the following I'm trying to click... <div class="closewindow"></div> Now of course this is buried below and inside tons and tons of other divs, but it doesn't have any

问题 I do very simple thing: I need to change VIDEO tag size via InvokeScript of WPF WebBrowser control. So it shows "Hello" but size doesn't changes at all. Note: If i open this page directly it changes size fine for any browser. private void btSize_Click(object sender, RoutedEventArgs e) { wb.InvokeScript("SetVideoSize"); } function SetVideoSize() { try { document.getElementById("player1").style.height = '400px'; document.getElementById("player1").style.width = '400px'; alert('Hello2'); } catch

问题 Using the context menu inside internet explorer allows you to inspect the element to see styles etc attached to a html element. Is there anyway that you enable this functionality inside the webbrowser control? (I am guessing it is not included to make it lighter, if so is there an alternative?)
