List replies in a winform

阅读更多关于 List replies in a winform

In my C# app I get an xml from a server that contains some replies like in a forum thread (with elements like author, time, body, title, whatever). When I get this xml, I create a new form in which i want to display these replies, and a little text box with an "add reply" button. I'd also like some edit buttons on perhaps my own replies in the reply list displayed in the form.

WebBrowser control to use IE9

阅读更多关于 WebBrowser control to use IE9

I want that the WebBrowser control to use IE9. IE9 is installed on the computer, but the WebBrowser control is still using IE8. I verified with http://www.whatbrowser.org/en/ . I try to make some changes to the registry (found a solution here) but is not working. I think it is the user agent string that is being passed to the site.
