问题 I'm trying to see if it's possible to read the registry from a Windows 8 app. I can usually use Registry.GetValue() but I don't have that option when creating the Win 8 app. Doing some digging shows that the Registry.GetValue() belongs to the Microsoft.Win32 namespace which isn't available in the Win 8 app references properties tab. I did some googling but I couldn't find any concrete evidence that you cannot read the registry. I fear that I won't be able to do this because of sandboxing Win

问题 Now that I have come to the realization that I can not use the normal .NET to write my Windows Store apps, I am trying to wade through the mess that is .NET for Windows Store apps. My latest discovery is that the System.Net.WebClient class is missing, and I needed to use it to upload a file. Had this class been there, I would have done something along the lines of: webClient.UploadFile("http://my.website/upload.php?a=" + someParam, "POST", filepath); Unfortunately, I can't do this in .NET for

问题 I am developing a Windows 8 Metro UI app. How can I set my app Tile background to Start Menu Color? 回答1: I am fairly certain you cannot programmatically access the Start screen color programmatically, though I cannot seem to find a clear reference to that newer than the Release Preview. You can set the tile background color explicitly via the app manifest 来源： https://stackoverflow.com/questions/12239357/change-tile-background-color-by-start-screen-color

问题 I have a WiX installer and a number of bootstrappers. We recently added SQL LocalDB support and found we needed to package .Net 4.0.2 to get it to work. I am now testing on Windows 8, and find that this patch fails and isn't actually needed for this OS. However, my installer fails because .Net 4.0.2 fails. I am trying to find a way of either skipping this patch in Windows 8 or just ignoring a fail for this patch? I have " InstallConditions " and " ExitCodes " in my package.xml , but I don't

问题 PASSWORD() according to MySQL documentation is a double SHA1 algorithm.

问题 Is it possible to create an app that "only" shows while using Share charm? I do not want the fullscreen app to be opened via live tile as there is no content to be displayed. I want it to be displayed only through Share charm. 回答1: No, it is not possible for an app to be shown only as a Share target. All Windows Store apps have a tile on the Start Screen that can be used to launch the app. 来源： https://stackoverflow.com/questions/13504624/windows-8-app-with-share-contract-only
