问题 So occasionally and seemingly randomly when developing WinRT apps Visual Studio goes through a lengthy process that starts with "Creating a new clean layout..." I would love more information about the build and deployment process involved with WinRT apps. I understand the concept of creating an application that runs in a sort of sandbox environment, but I'm looking for information about that sandbox environment. Also (this may sound silly) but what is different about the executable created

问题 I would like to prepare my site for windows 8 pinning and have been reading some documentation on how to add the various images and could figure out that it could be done by using metadata and according to instructions and help on this site I could actually build the following meta tags but i couldn't figure out where I can call the browserdetect.xml file assuming I have the file located at mysitee.com/upload/win8/browserdetetct.xml and the images in the same folder <meta name="application

问题 I want to emulate modal dialog in XAML Metro App. So I was going to set .IsEnabled = false on all controls apart from the one which will pose as a modal dialog.

问题 I'm not completely sure whether this belongs on SO, but I don't know where else to ask. While I was checking the loading speed of a web app of mine I noticed that apparently no HTTP response (no matter what type - html, css, js) is gzip/deflate compressed. That is, no response header like "Content-Encoding: gzip" is present in any request and the browser reports that the resource is not compressed. tested and confirmed in multiple browsers (IE10, FF 17, Chrome 23, Opera 12.10, Safari 5.x)

Thanks 回答1: Edit for windows-8.1 they have introduced a new property <TextBox x:Name="UserName" PlaceholderText="User Name"/> Please see Sergey Aldoukhov's answer For me this is the working solution that I got. If any one has better

问题 I am trying to create an app which does some work when it becomes visible, and does other work when it goes away. This is typically accomplished with the page visibility api (http://css.dzone.com/articles/using-html5s-pagevisibility) but this is not currently supported in windows 8: http://msdn.microsoft.com/en-us/library/ie/hh673553(v=vs.85).aspx There are callbacks onactivated and oncheckpoint but these are for the process lifecycle and are not necessarily related to app visibility.

问题 My custom Windows shell context menu handler works like a charm, for all Windows versions from XP to 7, but on Windows 8, 8.1 and 10, installing it breaks the Win + X menu (sometimes called "Power user menu" , or "Quick Access menu" , or "WinX menu" ): when hitting Win + X , the menu is displayed as expected, but its items do not work anymore (nothing happens when I click on them), except for the last four items at the bottom which still work as expected ( "Search", "Run", "Shut down/Sign out

问题 When I try to install XNA, I get the following error message : Your version of XNA Game Studio 4.0 and below isn't compatible with this version of Windows.

问题 I have recently upgraded my toolset from Win 7 x86 / Visual Studio 2010 to Win 8 x64 / Visual Studio 2012. However, now my native C++ dll compiles as x64 rather than x86. I haven't done anything other than move the code to the new O/S and load it into VS2012. Does anyone know how I can force it to compile for x86? 回答1: Go to your project's property pages, find the Linker -> Advanced -> Target Machine option, and make sure it is set to MachineX86 . 回答2: Go to Build --> Configuration Manager --
