问题 How can I accurately detect the current Windows operating system on a native (C/C++) project in Visual Studio 2012.3 for operating systems past Windows 8.1? I've looked in to VersionHelperAPI under MS recommendation, but this solution only applies to VS2013. Previously we used GetVersionEx() , but I'd like a solution that is more stable and future-proof in a way. It seems like MS is planning to deprecate this in the future. 回答1: The important thing is to include compatibility flags in

问题 I'd like to get Intellisense support in Visual Studio for the options objects I use in my method calls. It's common to configure a call to a function in Javascript with a catch-all options object - for example jquery's Ajax call uses: $.ajax(settings); Where settings is just an object like: $.ajax({ url: '/blah', data: { stuff: 1 }, method: 'POST', // etc }); Although it's an implicit object, the properties follow a specific class. Typically when you have something like this that's important

问题 In Team foundation server, In order to analyze a bug that is currently in production, I used the "get latest version" functionality to get the changeset that was active in production so that I could run my unit tests against it.

Is there an easy way to do this with tfs? 回答1: If you bring up the file/folder in Source Control Explorer, right-click and go to Properties it

问题 It has been a while since I've published my app to Azure. During that time frame, I've upgraded my system from 32-bit to 64-bit meaning a fresh install of Windows and Visual Studio. And Visual Studio Update 3 came out and was applied. When I went to publish an update today, I received the following: The following exception was thrown trying to publish: Root element is missing. My web.config file looks fine so I don't think it's this issue. The app works fine in debug mode so I don't think it

问题 Visual Studio 2012 (and earlier versions) are capable of compiling C code. Plain C , not C++. It would be a good feature if you wanted to avoid the runtime hazzle. I thought of compiling plain C binaries and was hoping to do so without the MSVCRT runtime. After adding the /TC (compile as C) option I was hoping to get a binary with only basic dependencies such as kernel32 and ntdll. But instead, this was linked: We want to use VS 2012 and not the runtime. The GCC compiler doesn't need it, so

问题 At the moment I have to write C# code in VS2012, (Before was: Java (Eclipse, IDEA)). May be I am strange guy, but I like when class name == class file name. Why in VS2012 no option to rename class file same as I renaming class name ? (Or I could not find it) I know that C# compiler do not care about matching class name and class file name, but I want to do it. I can`t find class by its file name if they are not same, it is annoying me very much aaaargh. Help me please, I'm tired finishing
