问题 I use Javascript to click a link in the webbrowser control. But I don\'t want to hear IE\'s \"click\" sound. Is there any way to do this? P.S. I don\'t want to change system settings.

问题 The new Windows 10 with Microsoft Edge has arrived. I want to ask you, how can I add it to my web browser control? I need it because the actual web browser control doesn\'t allow JavaScript and CSS3. I used to also add Chrome browser with the projects WebKit and Awesomium but they didn\'t remember the login credentials (I need them for my app) so I have to use I.E. unfortunately. 回答1: UPDATE May 2018: FINALLY Microsoft has made it easy. https://blogs.windows.com/msedgedev/2018/05/09/modern
