programmatically close win8 app

由 假装没事ソ 提交于 2019-12-07 01:07:49
问题 I've begun tinkering with making windows 8 apps And I want to make an exit button. The problem is that Environment.Exit() and this.Close() that I'd use in winforms isn't in scope here. anyone know how to close the app Programmatically? 回答1: Application.Current.Exit(); But closing a Metro app is not recommended. It is usually suspended. 回答2: Application.Exit But be careful. You can fail certification by having code which forcefully closes the App. Make sure to read up on Certification Guidance

Why exposed types must be sealed for WinMD/WinRT components?

由 ≡放荡痞女 提交于 2019-12-07 00:23:06
问题 VS compiler does not allow to create sealed exposed types for WINMD type library. Why is this restriction placed ? (I know about sealed types advantages, my question is with respect to Win RT components). 回答1: This is an architectural limitation, imposed by COM. Which sits at the core of any WinRT type, they are derived from IUnknown and IInspectable. The problem with COM is that it only supports interface inheritance but not implementation inheritance. Which was a strong COM design goal,

WinRT and software ClearType font rendering

由 女生的网名这么多〃 提交于 2019-12-06 23:49:06
问题 Does WinRT provides an option to fall back to software ClearType font rendering (as Direct2D do via "Direct2D and GDI Interoperability") or we will be stuck with somewhat blurry hardware font anti-aliasing only? 回答1: No. Windows on ARM will not support ClearType. This is by design. Instead, Windows on ARM tablets will be required to have a high DPI. http://www.istartedsomething.com/20120303/cleartype-takes-a-back-seat-for-windows-8-metro/ 来源： https://stackoverflow.com/questions/7487080/winrt

Windows 8 Flexboxes - Nesting Flexboxes with overflow enabled

由 老子叫甜甜 提交于 2019-12-06 23:44:30
I am attempting to create a horizontally flexible screen in a Windows 8 store app with several groups stretching out horizontally (contained in the outer Flexbox), and various fields under the groups listed vertically, wrapping from the bottom of the screen to the top as necessary (contained in a series of inner Flexboxes). This is a similar layout to a grouped Windows 8 ListView, but because I am displaying fields related to a single data item, and certain sections will contain ListViews elsewhere in the page, I cannot use a listview to display the data. I have run into a problem whenever the
