问题 I am writing a C++ CLI application how can I detect if any key is pressed by the user. I've seen that in c# but how can it be implement in c++ while(1) { while(/* code to check if any key is pressed*/) { //rest of the code // sleep function } } Hint: like in CLI games to move or to take certain action when a key is pressed or don't do any thing if no input is given. 回答1: On windows at least you could use GetKeyState 回答2: we can use _kbhit() function in c++. _kbhit is equal to 1 if any key is

问题 I'm trying to include a header file in a resource file (.rc). The path is something like "folder_a/sub_folder_b/file_name.h" The folder which folder_a is in is included in the project's c++ include directory. When I write the same #include directive in a .cpp file in the same project it compiles properly, but for the .rc file VS cannot find the header file. In the source editor window, when I right click the #include directive and choose 'open document', the popup error which states that it

问题 I'm trying to debug a C/C++ native DLL project from Visual Studio 2010. I'm attempting to follow these instructions: http://msdn.microsoft.com/en-us/library/c91k1xcf(v=VS.100).aspx I want to use the built-in debugger and be able to step code, examine structures, etc. as I would do with a regular .exe project.

问题 I wanted to know how to use the template for an Empty Visual C++ project to programmatically create a new solution with this empty project. The code (C#) I have right now is: string VSProgID = "VisualStudio.Solution.10.0"; Type solnObjType = System.Type.GetTypeFromProgID(VSProgID, true); Solution4 soln = (Solution4) System.Activator.CreateInstance(solnObjType, true); soln.Create(@"C:\NewSoln", "New"); soln.SaveAs(@"C:\NewSoln\New.sln"); string emptyVCProjPath = soln.GetProjectTemplate(

问题 I am using TR1 Regular Expressions (for VS2010) and what I'm trying to do is search for specific pattern for a group called "name", and another pattern for a group called "value". I think what I want is called a capture group , but I'm not sure if that's the right terminology. I want to assign matches to the pattern "[^:\r\n]+):\s" to a list of matches called "name", and matches of the pattern "[^\r\n]+)\r\n)+" to a list of matches called "value". The regex pattern I have so far is string

问题 Using C++0x, how do I capture a variable when I have a lambda within a lambda? For example: std::vector<int> c1; int v = 10; <--- I want to capture this variable std::for_each( c1.begin(), c1.end(), [v](int num) <--- This is fine... { std::vector<int> c2; std::for_each( c2.begin(), c2.end(), [v](int num) <--- error on this line, how do I recapture v? { // Do something }); }); 回答1: std::for_each( c1.begin(), c1.end(), [&](int num) { std::vector<int> c2; int& v_ = v; std::for_each( c2.begin(),
