  • Path managment in Linux programs

    - by petersohn
    I have a newbie Linux programming question. Suppose I have a project that uses Autotools for compiling and deployment, and I have data files that are to be installed in a location like /var/something or /usr/share/something etc., but in Autoconf, I can change these installation paths. How should the program find these files? How does it know where they are actually installed (if anywhere, since the program should work even if not installed, but run from where it was built)?

  • What is the best IDE to use with the Symfony framework?

    - by Failpunk
    I'm looking for an IDE with use with the Symfony Framework. I have a bit of experience using the NetBeans 6.5 IDE but it does not always seem to complete the class methods, plus it doesn't seem to have any PHP code snippets built in. Here are the features I would ideally like to have, in order of importance, from an IDE: Code completion of all the Symfony and Propel class methods (I can never remember them) Code templates,(class skeletons, HTML structures, Symfony templates?) Straight-forward code debugging Source Control

  • Suggestions for open source testing tool for cloud computing

    - by vikraman
    Hi, I want to know if there is any open source testing tool for cloud computing. We have built a cloud framework with Xen, Eucalyptus, Hadoop, HBase as different layers. I am not looking at testing each of these tools separately, but i want to test them from the perspective of fitting into a cloud environment (for example scalability of xen hypervisor to handle multiple VMs). Would be great if you can suggest me some tool (open source) for the above.

    I just built a site that relies on certain Unicode characters like &#9398;, but have just realized that IE doesn't show these characters? Is there some meta tag to get the browser to show it or how do you update IE to handle these Unicode characters?

  • How can I perform a reverse string search in Excel without using VBA?

    - by e.James
    I have an Excel spreadsheet containing a list of strings. Each string is made up of several words, but the number of words in each string is different. Using built in Excel functions (no VBA), is there a way to isolate the last word in each string? Examples: Are you classified as human? - human? Negative, I am a meat popsicle - popsicle Aziz! Light! - Light!

  • Using C# with Crystal Reports, How Can I Create 4-Up Subreports?

    - by C. Griffin
    The simplest example that I can provide for what I want to do is this: I need to create a Report, whose only requirement is that I have (4) of the same subreport on the page (imagine 4 portrait-oriented post cards on a page), each quadrant using a separate row from my datatable, yet all 4 are identical in terms of fields. If there are more than 4, it needs to carry over to a new page with the same format. I'm using C# and the built-in Crystal Reports Basic for the task.

  • Using Action Filters for user login in Asp.NET MVC?

    - by ripper234
    I recently built a site using Asp.Net. The way I chose to implement user login is through a base 'UserAwareController' class, that all controllers extend. It contained a reference to the UserRepository, and exposed a protected GetCurrentUser() method that concrete controllers could query. The whole process felt a bit wishy-washy to me. Is Action Filters a good alternative? What are its benefits? Is there something else I might be missing?

  • How can I get started with PHPUnit, where my class construct requires a preconfigured db connection?

    - by Ben Dauphinee
    I have a class that uses a lot of database internally, so I built the constructor with a $db handle that I am supposed to pass to it. I am just getting started with PHPUnit, and I am not sure how I should go ahead and pass the database handle through setup. public function setUp(/*do I pass a database handle through here, using a reference? aka &$db*/){ $this->_acl = new acl; } public function __construct(Zend_Db_Adapter_Abstract $db, $config = array()){

  • JSP application scope objects in Java library

    - by FrontierPsycho
    I am working on a preexisting web application built with JSP, which uses an external Java library. I want to make some JavaBeans that were instantiated with jsp:useBean tags available to the Java code. What would be a good practice to do that? I suppose I can pass the objects in question to every function call that requires them, but I'd like to avoid that.

  • Finding out the common / uncommon elements between two Arrays in PHP

    - by Veera
    Consider I have two arrays: $friends = Array('foo', 'bar', 'alpha'); $attendees = Array('foo', 'bar'); Now I need to populate a new array $nonattendees which contains only the elements which are in $friends array and not in $attendees array. i.e, $nonattendees array should be populated with 'alpha'. Is there any in built array operation available in PHP to achieve the above functionality or should I write my own for loops?

  • What is the best way to scale images in Java?

    - by Peter Kelley
    I have a web application written in Java (Spring, Hibernate/JPA, Struts2) where users can upload images and store them in the file system.

  • Building VS2008 solution using MSBuild 2010?

    - by Colin Desmond
    Is it possible to build a VS2008 solution (C# and VC++ projects) using the automated MSBuild built into TFS2010? When I niavely just run it, the build fails because the 2008 Solution file needs to be upgraded (and presumably so would the project files). Can I tell MSBuild 2010 to just build the 2008 files?

  • Is there a way to exit a Greasemonkey script?

    - by SimpleCoder
    I know that you can use return; to return from a Greasemonkey script, but only if you aren't in another function. For example, this won't work: // Begin greasemonkey script function a(){ return; // Only returns from the function, not the script } // End greasemonkey script Is there a built in Greasemonkey function that would allow me to halt execution of the script, from anywhere in the script? Thank you,

  • Visual marker when moving rows on DataGridView

    - by BlueRaja
    Users drag rows up and down in my DataGridView. I have the dragging logic down-pat, but I'd like there to be a dark marker indicating where the row will be placed after I let go of the mouse. (I've seen this in 1000 places before, but can't seem to find an example right now) Does anyone know how I'd go about doing this? Is this built-in, or would I have to draw my own marker (if so, how do I do that)? Thanks!

  • Linq Expression Trees in Compact Framework.

    - by Michal Drozdowicz
    The lack of expression trees in Compact Framework has bugged me for some time now, but I haven't really looked for a solution. Today, I've found a blog post about an alternative System.Linq.Expressions built on top of Mono System.Core and used e.g. by db4o (you can find it here). My question is - have you used this library and if so, what were your experiences with it (especially regarding performance)?
