问题 I need to create a custom security manager for a hosted WebBrowser control in my C# application. The hosted WebBrowser control should be independent from IE security and privacy settings.

The winform that hosts the WebBrowser control provides below implementation for GetSecurityId, MapUrlToZone

问题 I'm trying to use WebBrowser class, but of course it doesn't work.

问题 I'm writing a webpage, which will fully support mobile browsers. The page currently uses KnockoutJS to dynamically recalculate component sizes (and hide some components) based on the screen (or container) size. I have a problem with the android browser: When you click on a text field, the pop up keyboard causes a screen resize, which causes KnockoutJS to (correctly) re-render the display. This momentarily causes the text field to lose focus, which pop-up keyboard to disappear. If only I could

问题 I am doing browser automation using C#, and I would like to modify or possibly just eliminate event handlers on some of the html elements in webpages that I am looking at.

问题 I'd like to disable some features of a web app I'm building, if the browser is Tor Browser. Can I inside the browser itself (client side, not server side) find out if the browser is Tor Browser? I would prefer a solution that didn't issue any HTTP requests to match the browser's IP against Tor exit nodes. Background: In my case, Tor Browser pops up a dialog that asks the user "Should Tor Browser allow this website to extract HTML5 canvas image data?" , because, says Tor Browser, canvas image

Is there a nice elegant way to stop an .aspx page from resubmitting form data if the user requests a refresh from their browser? Ideally without losing the viewstate. EDIT: The most elegant solution for me turned out to be wrapping the relevant controls in an asp.net ajax UpdatePanel. Ta everyone. 回答1: There is no elegant way, but there are options. As stated in one of the other answers you can

问题 How can I code my Android application to start the web browser to display a given URL? (I'd rather not embed a web browser component into my app, but rather want to start the Android web browser to show the URL.)
