At WPF WebBrowser Mouse Events not working as expected, it is answered but I still cannot understand. Anyway, hooking up handlers to the events provided by the document of the WebBrowser can catch most mouse events but cannot use 'Back' & 'Forward' navigation button events.

How to disable caching in the .NET WebBrowser Control?

阅读更多关于 How to disable caching in the .NET WebBrowser Control?

问题 I have been googling for hours and trying to figure this out, and I just can't. I have 1 webbrowser control on a form, webbrowser1. Once I load a page, say google.com, if I use webbrowser1.refresh() or webbrowser1.navigate("google.com") , it's not reloading the page, it has it cached so it's just reloading the cache. This is terribly apparent especially on pages like forums or craigslist. I need to clear the cache between each refresh (not ideal) or disable caching all together, any ideas?

问题 I'm trying to use an invisible WebBrowser control to print a very simple HTML document.

Unfortunately, I haven't been very successful in making the output go to the right printer. The way it works right now is that before printing a document, the application determines which printer is to receive it, and sets the default printer accordingly. To do this it uses
