• When can argv[0] have null ?

  - by andrew-dufresne

  What I have understand about passing arguments to main() from command line is that argc has a minimum value of 1 and argv[0] will always have the program name with its path in it. If arguments are provided at the command line, then argc will have a value greater than one and argv1 to argv[argc-1] will have those arguments. Now a paragraph at this link says that argv[0] will be a string containing the program's name or a null string if that is not available. Now, how and when can argv[0] have null string? I mean program name with its path will always be available so when can it be null? Writer says that "if that is not available" but when and how it is possible that program name will not be available? Thanks for your time and support. Regards

• Tag property null when data binding

  - by rotary_engine

  Can anyone see what is wrong with this? The Tag property is returning null however the Binding for Id property is definately returning an int value. <ListBox ItemsSource="{Binding ElementName=myDomainDataSource, Path=Data}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Id, Mode=OneWay}" /> <HyperlinkButton Content="Edit" Tag="{Binding ElementName=Id, Mode=OneWay}" Click="Edit_Click" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> and then... private void Edit_Click(object sender, RoutedEventArgs e) { ContentControl c = sender as ContentControl; // exception - c.Tag is null int id = (int)c.Tag; } The Id property is showing a value on the UI, but doesn't seem to be getting stored in the buttons Tag property.

• Java, How to Instance HttpCookie from a String, any convenient ways?

  - by user435657

  Hi all, I have got a cookie string from HTTP response header like the following line: name=value; path=/; domain=.g.cn; expire=... I can parse the above line to key-value pairs, and, also it's easy to set the name and value to HttpCookie instance as this pair comes the first. But how to set the other pairs since I don't know which set-method corresponds to the name of the next name-value pair. Traverse all possible keys a cookie may contian and call the matched set-method, like below snippet? if (key.equalsIgnoreCase("path")) cookie.setPath(value); else if (key.equalsIgnoreCase("domain")) cookie.setDomain(value); That's foolish, any convenient ways? Thanks in advance.

• AppEngine and Django: including a template file

  - by PythonPower

  As the title suggests, I'm using Google App Engine and Django. I have quite a bit of identical code across my templates and would like to reduce this by including template files. So, in my main application directory I have the python handler file, the main template, and the template I want to include in my main template. I would have thought that including {% include "fileToInclude.html" %} would work on its own but that simply doesn't include anything. I assume I have to set something up, maybe using TEMPLATE_DIRS, but can't figure it out on my own. EDIT: I've tried: TEMPLATE_DIRS = (os.path.join(os.path.dirname(__file__), 'templates'), ) But to no avail. I'll try some other possibilities too.

• Check if a symlink has changed

  - by BCS

  I have a daemon that, when it's started, loads its data from a directory that happens to be a symlink. Periodically, new data is generated and the symlink updated. I want a bash script that will check if the current symlink is the same as the old one (that the daemon started with) and if not, restart the daemon. My current thought is: if [[ ! -e $old_dir || $(readlink "$data_dir") == $(readlink "$old_dir") ]]; then echo restart ... ln "$(readlink "$data_dir")" "$old_dir" -sf else echo no restart fi The abstract requirement is: each time the script runs, it needs to check if a symlink on a given path now points to a something other than it did the last time and if so do something. (The alternative would be to check if the data at the path has changed but I don't see that being any cleaner.) My questions: Is this a good approach? Does anyone have a better idea? Where should I put $old_dir?

• Best Design Pattern to Implement while Mapping Actions in MVC

  - by FidEliO

  What could be the best practices of writing the following case: We have a controller which based on what paths users take, take different actions. For example: if user chooses the path /path1/hello it will say hello. If a user chooses /path1/bye?name="Philipp" it will invoke sayGoodBye() and etc. I have written a switch statement inside the controller which is simple, however IMO not efficient. What are the best way to implement this, considering that paths are generally String. private void takeAction() { switch (path[1]) { case "hello": //sayHello(); break; case "bye": //sayBye(); break; case "case3": //Blah(); break; ... } }

• silently execute a MSI package from C#

  - by Keenan Molver

  Newbie question, let me try and make this as clear as possible. I have a program that needs to silently execute a msi package (well multiple but that's not the problem) The MSI packages are contained in a folder located in the same directory as my program. I've given it a simple name of "InstallFiles" for the time being. I'm not keen on using the full path name eg. C:\my program\another directory\another directory etc because it'll be put on multiple PC's, old and new, in which case the drive letter can change. So far I have: install.StartInfo.FileName = "msiexec"; install.StartInfo.Arguments = "/i F:\\InstallFiles\\JRE.msi"; install.Start(); install.WaitForExit(); However, when its launched it only gives me the Windows Installer switch information and then terminates, how do I get it to run and how would I go about changing the file path?

• Get/Set nested property values

  - by Daniel Deer

  I'll try to be more descriptive here. A Few Q's: using: var foo = new Foo() { Bar = new Bar() { Value = "Value" } }; var value = DataBinder.Eval(foo, "Bar.Value"); Or: This one It is possible to retrieve an internal nested property using property path syntax. Is there a way to set/trigger a nested property (a regular property not DependencyProperty) easily with some kind of simple mechanisms as described here? I want to acheive something like: string newValue = "Hello World!"; DataBinder.EvalSet(foo, "Bar.Value", NewValue); Is there any mechanism that support both property path (for nested objects) and XPATHs (if the objects are XPATH navigable of course) ? again, that supports get and set options. Thanks, DD

• Why are these strings escaping from my regular expression in python?

  - by dohkoxar

  In my code, I load up an entire folder into a list and then try to get rid of every file in the list except the .mp3 files. import os import re path = '/home/user/mp3/' dirList = os.listdir(path) dirList.sort() i = 0 for names in dirList: match = re.search(r'\.mp3', names) if match: i = i+1 else: dirList.remove(names) print dirList print i After I run the file, the code does get rid of some files in the list but keeps these two especifically: ['00. Various Artists - Indie Rock Playlist October 2008.m3u', '00. Various Artists - Indie Rock Playlist October 2008.pls'] I can't understand what's going on, why are those two specifically escaping my search.

• mod_perl and libs

  - by paulj3000

  Hi, I just installed my system with Oracle 64bit Linux5.4 running Apache Server version: Apache/2.2.3 and mod_perl 2. Now, I have my perl libraries set in a specific path: /my/perl/libs and I have adjusted my httpd.conf to compensate for this (I added the below): SetEnv MY_LIBS /my/perl/libs and in my cgi I'm setting my environment to compensate: use lib($ENV{'MY_LIBS'}); Now the problem: Sometimes my perl modules will recognize the path of /my/perl/libs and call all the functions appropriately, and sometimes they won't, thus thowing a 500 error. Some observations: when I restart apache (/etc/init.d/httpd restart), things work fine but then the 500 error comes up. Are there any ideas? What should I be looking at? Thanks

• JUnit unable to find tests in Eclipse

  - by mikera

  I have a strange issue with JUnit 4 tests in Eclipse 3.5 that I couldn't solve - any hints gratefully received! Initially: I had a test suite working properly, with 100+ tests all configured with JUnit 4 annotations. I'd run these typically by right clicking on my source folder and selecting "Run as JUnit test". All worked perfectly. Now: When I try to run the test messages all I get is an error "No tests found with test runner 'JUnit 4'". Any idea what is happening? I simply can't work out what could have changed to make this fail. My guess is that it is some configuration issue based on the build path or class path?

• Setting location based on previous parameter of $routeChangeError with AngularJS

  - by Moo

  I'm listening on events of the type $routeChangeError in a run block of my application. $rootScope.$on("$routeChangeError", function (event, current, previous, rejection) { if (!!previous) { console.log(previous); $location.path(previous.$$route.originalPath); } }); With the help of the previous parameter I would like to set the location to the previous page. This works as long as the "originalPath" of "previous.$$route" does not contain any parameters. If it contains parameters the "originalPath" is not transformed. Logging the previous objects returns the following output: $$route: Object ... originalPath: "/users/:id" regexp: /^\/users\/(?:([^\/]+)?)$/ ... params: Object id: "3" How can I set the location to the previous path including the parameters?

• On a Hudson master node, what are the .tmp files created in the workspace-files folder?

  - by Patrick Johnmeyer

  Question: In the path HUDSON_HOME/jobs/<jobname>/builds/<timestamp>/workspace-files, there are a series of .tmp files. What are these files, and what feature of Hudson do they support? Background Using Hudson version 1.341, we have a continuous build task that runs on a slave instance. After the build is otherwise complete, including archiving the artifacts, task scanner, etc., the job appears to hang for a long period of time. In monitoring the master node, I noted that many .tmp files were being created and modified under builds//workspace=files, and that some of them were very large. This appears to be causing the delay, as the job completed at the same time that files in this path stopped changing. Some key configuration points of the job: It is tied to a specific slave node It builds in a 'custom workspace' It triggers a downstream job that builds in the same custom workspace on the same slave node

• Eclipse is not importing jar dependencies between two projects in the same workspace

  - by jax

  Here is the situation. I have a java project "LicenseGenerator" in eclipse that depends on commons-codec. I have therefore added the commons-codec jar file to the build path. I have Junit tests and everything is working fine. I have made a different project in the same workspace - which happens to be an Android project - that needs to use my LicenseGenerator classes. I added LicenseGenerator to the "projects" tab in the build path - the classes were recognized and I was able to use them. Everything compiled and ran. However, when the part of the LicenseGenerator that used the commons-codec was called from my Android project I got the following error. Could not find method org.apache.commons.codec.binary.Base64.encodeBase64URLSafeString, referenced from method This basically tells me that the commons-codec was not packaged which the Android project, so I added the commons-codec to the android project as well but the same error appears. how do I fix this?

• Image expire time

  - by Jens

  The google page speed tool recommends me to set 'Expires' headers for images etc. But what is the most efficient way to set an Expires header for an image? In now redirect all image requests to an imagehandler.php using htaccess: /* HTTP/1.1 404 Not Found, HTTP/1.1 400 Bad Request and content type detection stuff ... */ header( "Content-Type: " . $content_type ); header( "Cache-Control: public" ); header( "Last-Modified: ".gmdate("D, d M Y H:i:s", filemtime($path))." GMT"); header( "Expires: ". date("r",time() + (60*60*24*30))); readfile( $path ); But of course this adds extra loading time for my images on first request, and I was wondering if there was a better solution for this.

• How do I use the Zend Youtube API correctly?

• BASH Script to cd to directory with spaces in pathname

  - by Rails Newbie

  Argggg. I've been struggling with this stupid problem for days and I can't find an answer. I'm using BASH on Mac OS X and I'd like to create a simple executable script file that would change to another directory when it's run. However, the path to that directory has spaces in it. How the heck do you do this? This is what I have... Name of file: cdcode File contents: cd ~/My Code Now granted, this isn't a long pathname, but my actual pathname is five directories deep and four of those directories have spaces in the path. BTW, I've tried cd "~/My Code" and cd "~/My\ Code" and neither of these worked. If you can help, THANKS! This is driving me crazy!!

• Uniforme distance between points

  - by Reonarudo

  Hello, How could I, having a path defined by several points that are not in a uniform distance from each other, redefine along the same path the same number of points but with a uniform distance. I'm trying to do this in Objective-C with NSArrays of CGPoints but so far I haven't had any luck with this. Thank you for any help. EDIT I was wondering if it would help to reduce the number of points, like when detecting if 3 points are collinear we could remove the middle one, but I'm not sure that would help.

• C++ shared libraries

  - by saminny

  Hi, I am trying to get my head around the way shared libraries work in the c++ unix environment. I understand we only need header files and no shared libraries specification when compiling code. But if I want to create an executable or shared library from my compiled files, do I need to specify shared library dependencies (those are dynamic)? And do the paths of shared libraries need to match the path at runtime loading? I am using Linux 2.6.18-164.11.1.el5 #1 SMP x86_64 GNU/Linux I am having a problem where my code is not able to pick up a library at runtime. I have tried setting LD_LIBRARY_PATH and PATH. But at runtime when I run the executable, I get the following error: Error: librc.so: cannot open shared object file: No such file or directory Sam
