问题 I have an Azure project with an MVC4 role where I have added the Visual C++ 2012 Runtime Library setup file, and a script to silently install it. The script works and the library gets installed, the only problem is that the task never finishes and the installation process never exits, which then blocks the role from starting: I connected to the server using Remote Desktop, and by looking at the task manager I can see the process vcredist_x64.exe : (2 of them actually, but I think that's

问题 The following code doesn't compile in VS2012 class Zot { public: int A() { return 123; } }; int _tmain(int argc, _TCHAR* argv[]) { std::function<int (Zot*)> fn = &Zot::A; return 0; } However, changing the assignment to std::function<int (Zot*)> fn = std::bind(&Zot::A, std::placeholders::_1); Does work. There are a lot of online examples that show the original syntax. Did something change in the C++11 spec to disallow this syntax? Is there a valid shorter form for the assignment? Edit : the

问题 I am having a lot of trouble finding any documentation on the header included with vs2012. I see that it is mentioned here but they don't provide a link on how to use it. What I am really looking for is documentation for how to use it, with the visual studio implementation being preferred. Thanks 回答1: The <filesystem> header is not part of C++11; it is a proposal for C++ TR2 based on the Boost.Filesystem library. Visual C++ 2012 includes an implementation of the proposed library. See the MSDN

问题 I have a .NET 4.5.2 application that's deployed via ClickOnce. It uses the Magick.NET library, which requires the Visual C++ Redistributable for Visual Studio 2012. I've tried it with the 2013 package, but it still needs the 2012 version to work. Unfortunately, the only version listed under the possible Prerequisites in Visual Studio 2013 is the 2013 version. Other version are nowhere to be found: How do I include the Visual C++ 2012 Runtime Libraries with my ClickOnce app in Visual Studio

问题 I plan to write application in C using Microsoft Visual Studio 2012. The problem is that I can't find a way to compile it right in the editor. I found this solution http://msdn.microsoft.com/en-us/library/bb384838.aspx but I dont like it. Can you recommend me a way to compile C program right in the Visual Studio 2012? 回答1: It is a little bit tricky to compile plain C90 and C++x0 (only partially supported) projects in VS2010 (and probably Visual Studio 11, I haven't tried native development in
