问题 I installed both Bonjour SDK for Windows v2.0.4 and Bonjour 3 for Windows 8 and 8.1 from Apple's website on my Windows 8.1 machine. When I try to use the Bonjour package in my C# code, the package is not recognized and I can't use the SDK. Any ideas why this would happen? Edit: Turns out it was because Interop.Bonjour.dll was not among the References, so I added it and now I don't get the error. However, when I try to use a class of Bonjour package, like below: DNSSDService service = new

问题 Windows 8 does not seem to persist sort orders on individual folders. I'm guessing when explorer.exe terminates (like when rebooting) these preferences get discarded? Beats me, all I know is after a time (like a few days) those preferences get totally lost. Is there a way to duplicate programmatically sorting folders in Windows Explorer (opting one of the 'Sort by' options in the context menu)? Such that, say I have a folder opened in the Windows UI. Say the folder is currently set to sort by

问题 After installing ReSharper I've noticed a problem with the IntelliSense; In the image it is clearly visible that the IntelliSense of Visual Studio is displayed over the one of ReSharper (which by the way has the focus, so using the arrow keys will move the highlight section of the completion list below). I've tried to do several things without any result (always with VS restart): Switch from ReSharper IntelliSense to VS (back and forth) Limit ReSharper IntelliSense to some selected languages

问题 I am very new to Windows 8 so please bear with me. I am styling a ListView in xaml for a Windows 8.1 Store app. I would like to customize the offset distance that a ListViewItem can be swiped horizontally to select it. I have looked through the ListViewItem and ListView styles in the generic.xaml file and edited them in my App.xaml file... but I haven't been able to find any settings that made the correct change. In the ListViewItem style with the key ListViewItemExpanded, I tried changing

问题 I have a scrollview with a big grid containing two smaller grids. the grids are supposed to scroll together vertically, but only the right grid should scroll horizontally. This is because the information in the left grid is needed as a reference while the right grid can contain 100+ columns. I have already tried putting the grids in separate scrollviews and linking them with an eventhandler. But I didn't find any code to do this in a Windows 8.1 application. Is there any way to do this for

问题 In Windows 8, you were able to create your own themes for your application (here's a tutorial). In Windows 8.1 Applications, themes are handled differently: you can change them at run-time and set a theme for a specific control in your XAML (if you don't want to apply the theme to the whole Application).
