relative-path

问题 I'm storing the file path in the database as ~/FolderName/FileName and when i try to open the file using System.IO.FileInfo(filePath) in this manner. It is not able to decipher the file path. Moreover i'm using this statement in a class DownloadFile, so i'm not able to use Page.Server.MapPath. Is there a work around for this problem. These are the following lines of code that i'm using: if (dr1.Read()) { String filePath = dr1[0].ToString(); HttpContext.Current.Response.ContentType =

问题 I write a small javascript library, it use a image. I want to build the directory structure like this: /lib /mylib main.js /img main.png /other libraries... index.html But if I hard-code the image path lib/mylib/img/main.png , my library can't be used in other directory structure.

问题 I would like to display an image on my dialog which could be located in a directory relative to the one the .exe is located in, e.g. project - data -- logo //<-- that's where the image is located -bin //<-- that's where the .exe is in A default image should be included in the .exe but on displaying the dialog, the \data\logo directory should be checked first and if an image with the given filename could be found there that one should be used for display instead of the one that is inside the

问题 I have a project having the following folder: resources/xml-schemata/someXMLschema.xsd A class inside my project uses this xml schema to validate xml files before importing them. This class has a local variable pointing out the schema path: schemaFilePath = "resources" + File.separator + "xml-schemata" + File.separator + "someXMLschema.xsd" Of course this works locally. Now I want to put my tool in a jar to give to other people. But the project using the jar can't find the schema, because of

问题 This probably has a simple answer, but I'm working on a test suite that requires an input file that is in a different folder. I'd like to use a relative path, like this: @graph = Graph.new('../lib/test_input.txt') But Ruby doesn't like that. What's the best way to use a relative file path like that? Thanks 回答1: If you mean relative to the current file, you'll probably want something like: @graph = Graph.new(File.expand_path(__FILE__, "../lib/test_input.txt")) If you mean relative to the

问题 I need a fast and reliable way to map an absolute or relative local path (say ./images/Mafalda.jpg ) to it's corresponding absolute URL, so far I've managed to come up with this: function Path($path) { if (file_exists($path) === true) { return rtrim(str_replace('\\', '/', realpath($path)), '/') . (is_dir($path) ? '/' : ''); } return false; } function URL($path) { $path = Path($path); if ($path !== false) { return str_replace($_SERVER['DOCUMENT_ROOT'], getservbyport($_SERVER['SERVER_PORT'],

问题 I believe this is an Apache .htaccess issue, and yet, maybe not. Maybe I am looking at the problem from the wrong angle, and thus can't find the proper solution. I am building a web app + hybrid mobile app. I would like to share the exact same code base, without having to tweak anything manually to deploy my app to Android or iOS, otherwise, the process of deploying will be hacky and painful. What I want is to take the web app repository, shove it into Cordova's box (you dirty man ;) , and it
