relative-path

问题 I need to find the full path to the Perl script I'm currently running, i.e. for ~/dir/my.pl I would need it to be "/home/user/dir/my.pl". The $0 will give me "~/dir/my.pl". for ./my.pl I would still need "/home/user/dir/my.pl" etc. Thanks! 回答1: Use the FindBin module: $ cat /tmp/foo/bar/baz/quux/prog #! /usr/bin/perl use FindBin; print "$FindBin::Bin/$FindBin::Script\n"; $ PATH=/tmp/foo/bar/baz/quux prog /tmp/foo/bar/baz/quux/prog $ cd /tmp/foo/bar/baz/quux $ ./prog /tmp/foo/bar/baz/quux/prog

问题 My php file is here: D:/Appserv/www/x/y/file.php I want to load stuff from this folder: E:/foldie I don't know what path will lead me there. $somePath="HELP ME HERE!!!!" $dir=opendir($somePath); //looping through filenames while (false !== ($file = readdir($dir))) { echo "$file\n"; } 回答1: Use full Windows path to the file it should be working: "E:\folder\file.txt" or just copy the file in the local/project directory for testing purpose. 回答2: Set $somePath = "e:\\foldie" . If that doesn't work

问题 I have a DataGrid which has a DataGridTemplateColumn that uses the ItemsSource binding of the DataGrid, but in the ComboBox of the DataGridTemplateColumn, I want to be able to bind to the ViewModel for the View instead of the ItemsSource. <DataGrid ItemsSource="{Binding ModelValues, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" > <DataGridTemplateColumn Header="myHeader" Width="200"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <ComboBox DisplayMemberPath="Value"

问题 I have a standard MVC3 project with layout page etc. Now I need to make pretty URLs. I started playing with URL rewrite module. I'm trying to translate http://localhost/Photographer/Pablo into http://localhost/category-about.aspx?displayName=Pablo , and here is my rewrite rule (very simple!): <system.webServer> <rewrite> <rules> <rule name="about" patternSyntax="Wildcard"> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add matchType="IsDirectory" negate=

问题 I don't necessarily need to run it at server, however, I would like to use the ~/js/somefile.js syntax. Previously, I had just set everything with Absolute paths and set my project to be at the root level. SO, I'd just declare all my stylesheets, background images and javascript files something like /css/somefile.css However, for this project, it doesn't run as root. I can't put runat="server" on a script tag. I can put it on a link tag, though. This must be a common problem with a few simple

问题 I feel like a nub for asking this, but I can't figure it out.. I've found several posts (here's one) saying that to use a relative path from the root of your site, start the path with / , ex: <img src="/images/img1.jpg" /> My file hier. looks like -root -images -css -index.aspx -subFolder -test.aspx Now when I use the src path as shown above, it doesn't work in either index.aspx or test.aspx, but when I remove the / , it works for index.aspx. In test.aspx, I used ../images/img1.jpg and it

问题 I'm trying to implement something similar to this or this. I've created a user control, a web service and a web method to return the rendered html of the control, executing the ajax calls via jQuery. All works fine, but if I put something in the user control that uses a relative path (in my case an HyperLink with NavigateUrl="~/mypage.aspx") the resolution of relative path fails in my developing server. I'm expecting: http://localhost:999/MyApp/mypage.aspx But I get: http://localhost:999

问题 I have deployed a app on tomcat. Some of the libraries used by the app use relative paths to resources. Therefore, they search the resources in TOMCAT-HOME/relative-path. I can not create links nor copy resources to TOMCAT-HOME folder. Also I can not change the code of the libraries and use application context. Can I somewhere in Tomcat configuration specify the "working directory" for this app alone. I've tried using Context container, but I can not get my head around it. Thanks. 回答1: You

问题 A similar question is HERE but with no solution. I am able to run my project on localhost but once deployed, loading the metadata fails. Looking into chrome developper tools, the request is sent to http://www.domain.org/breeze/metadata instead of http://www.domain.org/projectname/breeze/metadata . On my localhost, the metadata loads as http://localhost:xxxx/breeze/Metadata . My entity manager is declared as new breeze.EntityManager('breeze') . If I change the entitymanager to new breeze
