问题 If I have a metro StorageFolder, I can get a file using GetFileAsync(fileName). However, how do I know if the file exists in the first place? Right now, I catch an exception but it does not seem like the right thing to do. 回答1: According to Microsoft, they want us to catch the exception. The reasoning they gave me is that them providing a File.Exists API would open you up to race conditions where the file's existance might change between when you check and when you try to use the file.

问题 I upgraded to win 8. Now I run my VS 2012 under admin privileges and I'm creating a website in MVC 4. I checked different solutions online and none have worked. I have a javascript file in my solution but when I put a breakpoint in it, at runtime I see "no symbols have been loaded for this document". I had this issue couple years back with VS 2008 and somehow it resolved. I don't remember if I did change anything at all. Now it's back! except i'm not on win XP and VS 2008. the .pdb files are

问题 Pounding on the update button in this screenshot does nothing. Nothing is downloaded, installed, etc. No message, nothing at all! Clicking "Release Notes" and "More Information" also does nothing. Searching for this update yields nothing useful, too. What ever shall I do? 回答1: Is Google Chrome your default browser by chance? I see the same behavior in that case, but not when IE or Firefox is. What Wade suggested earlier is precisely the file that pressing that button would have downloaded for

The effect is not seen if I scroll with my finger, did not arrive until founded in the scrollbar. How i can avoid this window movement? How I can lock my windows and do not permit to move when I scroll at the

问题 I'm trying to make a simple Windows Store game in C# and XAML, one that involves hexagonal tiles moving about. This is mostly to help me learn C# and XAML as I've never worked with graphics or even UI coding before. I've got a method that can move a single hex to the target coordinates, but looking at it now I realize that it is impossible to do multiple moves at once, which is absolutely necessary. I feel like there's got to be something fundamentally off in my approach, multiple objects

问题 My Windows Store (aka Windows 8) application uses the default Grid Application template to show the items. The item template there includes an image with overlaid text information. To diminish the size of application I do not store the images for every item, instead I save an Uri with absolute path (http) to the webserver where the image resides. I modified the standard template to bind to the image Uri (I had to convert the Uri to string for this to work properly) and now whenever I start

问题 To publish an app in the Windows 8 store, you must have a store account. There are two types of accounts: individual and company. These accounts are NOT identical. Some declarations in your app's manifest cannot be used if your have an individual account. Which declarations cannot be used if your have an individual account? 回答1: Here is a full list of differences between the individual and company accounts for the Windows Store that I've been gathering. To address your specific question,

问题 I'm making my first Windows 8 client. This is also the first time I've used async methods to load a property so please forgive me if this is a noobie question. I have a WCF service and started from the Split Page template in visual studio for the client (but I'm going to pretty much replace everything). When I get the data into my Views directly inside of the "SplitPage" code behind everything is loaded properly and shows up. However, when I try to use MVVM the property doesn't have any items
