问题 I am using Sitefinity 5.1 and RadGrid in this example. I have been troubleshooting one of our pages on development server this morning and I have confirmed that it behaves differently on the page with the styling (template) than on the barebones page (no styling, no scripts etc): The page does not work in Chrome but does work in IE and Firefox The page on a bare-bones page (no template, header, or anything else) works in IE, Firefox and Chrome Code used: Response.Redirect(String.Format("~

问题 I am trying to display an image on a jsp page. I am developping using spring security/mvc. this is the part of jsp page : <a href="/images/logo.png"> <img src="/images/logo.png" alt="logo"> </a> and this is the configuration : @Configuration @EnableWebMvc @ComponentScan(basePackages ="...") public class HelloWorldConfiguration extends WebMvcConfigurerAdapter { @Bean(name="HelloWorld") public ViewResolver viewResolver() { InternalResourceViewResolver viewResolver = new

问题 Let's say we have a fully connected directed graph G . The vertices are [a,b,c] . There are edges in both directions between each vertex. Given a starting vertex a , I would like to traverse the graph in all directions and save the path only when I hit a vertex which is already in the path. So, the function full_paths(a,G) should return: - [{a,b}, {b,c}, {c,d}] - [{a,b}, {b,d}, {d,c}] - [{a,c}, {c,b}, {b,d}] - [{a,c}, {c,d}, {d,b}] - [{a,d}, {d,c}, {c,b}] - [{a,d}, {d,b}, {b,c}] I do not need

问题 I'm currently learning about PHP archives (Phars) and I know that in PHP __FILE__ always is the absolute filename of the currently executing file. But to which file does __FILE__ point to if the script is inside a Phar? Is it the absolute filename of the Phar itself, or the Phar-URL to the current script inside the Phar? For example: If I have a Phar located at /path/to/my.phar which contains a stub script, and a PHP script located at phar:///path/to/my.phar/inside/inner.php . What would _

问题 In my ruby script,I required the gmail gem: require 'rubygems' require 'gmail' when running in shell,it works ok: ruby my-script.rb while when I put it in a cron job,it failed to execuate: * * * * * cd /to/script/directory;/usr/local/rvm/rubies/ree-1.8.7-2011.03/bin/ruby ./my-script.rb the log shows that the gmail gem can not be loaded: /usr/local/rvm/rubies/ree-1.8.7-2011.03/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require': no such file to load -- gmail

问题 I'm building a web app that has php files spread out through different directories, so a typical file may have several includes. All these files everywhere. a php file may look like this: include('../../some.php'); require('../../some.php'); and in another file you may have something like this: include('../../../../some.php'); require('../../../../some.php'); point being, this can get a little bit out of hand, and somewhat difficult to keep track of. Is there a way I can do this so that I don

问题 Is there a way to programmatically find the path of an R script inside the script itself? I am asking this because I have several scripts that use RGtk2 and load a GUI from a .glade file. In these scripts I am obliged to put a setwd("path/to/the/script") instruction at the beginning, otherwise the .glade file (which is in the same directory) will not be found. This is fine, but if I move the script in a different directory or to another computer I have to change the path. I know, it's not a

问题 I want to use the QString.split(' ') method to split a input command into the command QStringList commandList = command.split(' '); however command has a UNIX path at the end of it. i.e. it looks something like QString command = new QString("caommand -a -b /path/to\ specific/file"); the path command is specified by the user at runtime(the user escapes any spaces in the path). For some reason command.split(' '); does not escape the spaces. I am new to QT, how does it escape spaces? Thanks for

问题 We know that we could use urllib.urlretrieve to download file via HTTP to local file system. For example: import urllib urllib.urlretrieve ("http://www.example.com/songs/mp3.mp3", "mp3.mp3") I wonder where is the default path if we download a file like mp3.mp3 ? I have read python document. urllib.urlretrieve(url[, filename[, reporthook[, data]]]) Copy a network object denoted by a URL to a local file, if necessary. If the URL points to a local file, or a valid cached copy of the object

问题 I'm having trouble selecting the root of the solution in my ASP.NET Application. I have three applications inside this solution, a Web app, an API and an app for Reports. I was trying to select my Reports app from the Web app in code using Server.MapPath but I can't get to the folder. I tried Server.MapPath("\Tagus.TMS.Reports/Media/VoyageControlReport.rpt") from inside the web app. How can I get that app path? 回答1: The Server.MapPath will use the "application level of IIS" to determine the
