path

问题 In my node.js app I have functions which can be passed either OS-style paths e.g. c:\my\docs\mydoc.doc (or /usr/docs/mydoc.doc or whatever is local) File URLS e.g. file://c:/my/docs/mydoc.doc (which I'm not sure about the validity of '\'s in??) Either way, I need to check to see if they refer to a specific location which will always exist as a local OS-style path e.g. c:\mydata\directory\ or /usr/mydata/directory Obviously for OS-style paths I can just compare them as strings - they SHOULD

问题 I'm trying to use back slash in C++ in a string like this : HWND hwnd = FindWindowA(NULL, "C:\Example\App.exe"); So for this example I would get these errors/warnings :"unknown escape sequence: '\E'" "unknown escape sequence: '\A'" . Since I need to type in the exact name of the window , is there any way to avoid using back slashes or stop the compiler from interpreting them as "escape sequences" ? 回答1: You have to escape them properly, C++11 added raw string which eases this thing: HWND hwnd

问题 I want to solve a 'game'. I have 5 circles, we can rotate circles into left or into right (90 degrees). Example: Goal: 1,2,3,....,14,15,16 Ex. of starting situations: 16,15,14,...,3,2,1 I'm using BFS. Heuristic function: heuristic(NextState,Goal,H)), Desctiption of function: For each number 1 <= i <= 16, find the minimum number of rotations needed to put i back in its correct position (disregarding all other numbers) Take the maximum over all these minimums. This amounts to reporting minimum

问题 I'm working on 2d game dev project. It's some kind of board game. As background I have board game with path, that isn't real circle, but some kind of wavy line. Objects are moving across that path. On touch event...I need to my player's object get at that exact position, but they need to follow that path. How to translate (draw) objects over some custom path? 回答1: You could draw your path (i.e. your wavy line) using an actual Path object onto the Canvas , and then use PathMeasure to calculate

问题 I developed a DLL in Managed C++ which loads some plugins (implemented in any .NET language) at runtime using System.Reflection.Assembly.LoadFile. The interface which is implemented by all plugins is implemented in C#. It's used by the Managed C++ code like this: #using <IMyPluginInterface.dll> // Make the 'IMyPluginInterface' type available ref class PluginManager { List<IMyPluginInterface ^> ^m_plugins; // Load all plugins in a well-known directory. void load() { for ( string dllFile in

You are welcome to correct my syntax if it is wrong or help me by referring other code snippets. byte[] data = (byte[])listDataset.Tables[0].Rows[0][0]; System.IO.FileStream file = System.IO.File.Create(Server.MapPath(".\\TmpImages\\"+hfFileName+".pdf ")); file.Write(data, 0, data.Length); file.Close(); 回答1: It could be a

问题 I sometimes see people refer to file system paths (POSIX/Windows) as both URIs and URLs. I'm no file system buff, but I have yet to find a file system path that conflicts with my understanding of the URL format. That is, of course, given that it includes the scheme name (e.g. file://localhost/path/to/file.txt). File system paths are most definitely URIs - I mean, what's not - so everyone referring to file system paths as URIs is inside the safe zone. But is it safe to call them URLs? If the

问题 I'm making a setup script in Inno and I was wondering, how can I get non "hardcoded" path. Here is example: Thanks in advance! SOLUTION: You can get .iss folder by using predefined variable SourcePath Usage would be like: {#SourcePath}\???\bin\x86\Release\???.exe Thanks all who contributed! 回答1: The reference about the source directory says (emphasized by me): By default, the Setup Compiler expects to find files referenced in the script's [Files] section Source parameters, and files
