  • Advanced Array Sorting in Ruby

    - by Ruby Beginner
    I'm currently working on a project in ruby, and I hit a wall on how I should proceed. In the project I'm using Dir.glob to search a directory and all of its subdirectories for certain file types and placing them into an arrays. The type of files I'm working with all have the same file name and are differentiated by their extensions. For example, txt_files = Dir.glob("**/*.txt") doc_files = Dir.glob("**/*.doc") rtf_files = Dir.glob("**/*.rtf") Would return something similar to, FILECON.txt ASSORTED.txt FIRST.txt FILECON.doc ASSORTED.doc FIRST.doc FILECON.rtf ASSORTED.rtf FIRST.rtf So, the question I have is how I could break down these arrays efficiently (dealing with thousands of files) and placing all files with the same filename into an array. The new array would look like, FILECON.txt FILECON.doc FILECON.rtf ASSORTED.txt ASSORTED.doc ASSORTED.rtf etc. etc. I'm not even sure if glob would be the correct way to do this (all the files with the same file name are in the same folders). Any help would be greatly appreciated!

  • Objective-C Framework PSMTabBarControl does not work - NSTabView Tabs with Style

    - by ahmet2106
    Hello everybody In my App I'm trying to get PSMTabBarControl working, but all I do - nothing... I have copied the framework File in my Frameworks folder of my App, then included it. In my InterfaceBuilder (1.3.2) I was able to drag and drop the PSMTabBarControl to my Window and link it with the NSTabView (PSM - tabView - NSTabView && NSTabView - delegate - PSM), but after i tried a Demo (apple+r) I cant see the Tabs... Tried all I can - but dont know why.. Am I doing sth. wrong? Which other Framework or Source I can use to create Tabs like Firefox oder Safari? Thank you!

  • custom tag 'cannot be resolved to a type'

    - by lotus99t
    I have a custom tag, packaged into a library jar that is included in my web apps war file. I get the following error: An error occurred at line: 66 in the jsp file: /WEB-INF/jsp/portlet/portfolio/operations/operationsInfo.jsp org.apache.jsp.tag.meta.form.WidgetFactory_tag cannot be resolved to a type 63: <c:forEach var="fldCfg" items="${config.page.fields}" > 64: <tr> 65: <td><form:Label fld="${fldCfg}"/></td> 66: <td><form:WidgetFactory fld="${fldCfg}" decodesMap="${decodesMap}" command="${operationsInfoBean}" dateFormat="${preferredDateFormat}"/></td> 67: </tr> 68: </c:forEach> 69: </table> But it doesn't seem to complain about Label which is in the same taglib. I've confirmed that the jar is in the war and that the tag file is in the jar and the that the TLD (in META-INF) expressly defines 'WidgetFactory' Why am I getting this error?

  • Mercurial/.hgignore - How do I ignore everything but the contents of a folder?

    - by Beibin
    I have a NetBeans project and the Mercurial repository is in the project root. I would like it to ignore everything except the contents of the "src" and "test" folders, and .hgignore itself. I'm not familiar with regular expressions and can't come up with one that will do that. The ones I tried: (?!src/.*) (?!test/.*) (?!^.hgignore) (?!src/.|test/.|.hgignore) These seem to ignore everything, I can't figure out why. Any advice would be great.

  • jQuery select image in div if image parent does't have a certain class.

    - by Alex
    Wordpress wraps images with captions in a div with a class of .wp-caption. I'm looking for a way to select images that don't have this div so I can wrap them in different div. (to keep a consistent border around all the images) <div class="blog-post-content"> <div id="attachment_220" class="wp-caption alignleft" style="width: 310px"> <a href="/somewhere/"><img class="size-medium wp-image-220" src="/path/to/image" alt="" width="300" height="280" /></a> <p class="wp-caption-text">Caption Text</p> </div> <p>This is the body of the post</p> </div> To test my selector, I'm just trying to add a green border. I can handle the .wrap() once the selector is working. The most promising of my attempts is: $('.blog-post-content img').parent('div:not(".wp-caption")').css('border', '2px solid green'); ... but no luck.

  • How to get window opened/closed/minimized messages from a native app?

    - by Josh Santangelo
    It's tough to write a good title for this one. I'm working on a WPF application which needs to know about the existence of all other open windows on the system. I'm able to do this by calling the native EnumWindows method just fine, and I can call other native methods to filter out just the windows I'm interested in. This works well. The problem I'm having is that I want to know when a window is opened or closed (and, ideally, minimized). I can do this by polling with EnumWindows, but I'm finding that to be pretty slow, even if I push it off to another thread. Is there a better way to get notifications of window opened/closed/minimized? Keep in mind that my knowledge of non-managed code is pretty limited.

  • ASP.MVC 2 RTM + ModelState Error at Id property

    - by Zote
    I have this classes: public class GroupMetadata { [HiddenInput(DisplayValue = false)] public int Id { get; set; } [Required] public string Name { get; set; } } [MetadataType(typeof(GrupoMetadata))] public partial class Group { public virtual int Id { get; set; } public virtual string Name { get; set; } } And this action: [HttpPost] public ActionResult Edit(Group group) { if (ModelState.IsValid) { // Logic to save return RedirectToAction("Index"); } return View(group); } That's my view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Group>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% using (Html.BeginForm()) {%> <fieldset> <%= Html.EditorForModel() %> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> <div> <%=Html.ActionLink("Back", "Index") %> </div> </asp:Content> But ModelState is always invalid! As I can see, for MVC validation 0 is invalid, but for me is valid. How can I fix it since, I didn't put any kind of validation in Id property? UPDATE: I don't know how or why, but renaming Id, in my case to PK, solves this problem. Do you know if this an issue in my logic/configuration or is an bug or expected behavior? Thank you

  • WPF/.NET data access models - resource recommendations

    - by jasonk
    We're in the early design/prep phases of transferring/updating a rather large "legacy" 3 tier client-server app to a new version. We’re looking at doing WPF over Winforms as it appears to be the direction Microsoft is pushing development of the future and we’d like the maximize the life cycle/span of the apps. That said during the rewrite we’d like to make as many changes to our data access/presentation model to improve performance as much as possible up front as many. I’ve been doing some research along that vein but the vast majority of the resources I've found that discuss WPF focus only simple data tracking apps or focus on the very basics UI design/controls. The few items that even discuss data presentation are fairly elementary in depth. Are there any books/articles/recommended reading/other resources recommended for development related to large enterprise level business apps? Any “gotchas” that should/could be avoided? General advice to minimize the time underwater

  • Force float left with no line break no matter what

    - by Tesserex
    I'm guessing this isn't possible, but here goes. I have two tables, and I'm trying to get them to sit side-by-side so that they look like one table. The reason for this, instead of using one larger table, is that the data in the second table needs to be handled on a column basis, not row basis, for performance reasons like caching and AJAX-fetching data. So rather than have to reload the whole table for a single column, I decided to break the column out into a separate table, but have it visually seem like a single table. I can't find a way to forcibly put the second table next to the first. I can float them, but when the first table is too wide, the second one breaks to the next line. Here's the kicker: the width of the first table is dynamic. So I can't just set a huge width to their container. Well, I could set a huge width, like 1000%, but then I have a huge ugly horizontal scroll bar. So is there any way to tell the second table "Stay on that same line, no matter what! And line up right next to the previous element please!"

  • How do I overcome the "The symbolic link cannot be followed because its type is disabled." error whe

    - by David Arno
    Following on from a previous question, I am creating a symbolic link on a Server 2008 from a Vista machine using UNC paths. I can create the link just fine. I can go to the Server 2008 box and double click on the link in explorer to open the target file. What I cannot do though is use FileCreateW to get a handle to the UNC path link (from the Vista box). When I try it, it fails and GetLastError() returns error code 1463 (0x5B7), which is: The symbolic link cannot be followed because its type is disabled. Can anyone tell me how to enable its "type" in Server 2008 (assuming the error means what it says)?

  • Programmatically creating vector arrows in KML

    - by mettadore
    Does anyone have any practical examples of programmatically drawing icons as vectors in KML? Specifically, I have data with a magnitude and an azimuth at given coordinates, and I would like to have icons (or another graphical element) generated based on these values. Some thoughts on how I might approach it: Image directory (a brute force way): Make an image director of 360 different image files (probably batch rotate a single image) each pointing in a cooresponding azimuth. I've seen things like "Excel to KML," but am looking for code that I can use within a program, rather than a web utility. Issue: Arrow does not contain magnitude context, so that would have to be a label. I'd rather dynamically lengthen the arrow. Line creation in KML: Perhaps create a formula that creates a line with the origin at the coordinate points, with the length of the line proportional to the magnitute, and angled according to azimuth. There would then be two more lines, perhaps 30 degrees or so extending from the end of the previous line to make the arrow head. Issues: Not a separate image icon, so not sure how it would work in KML. Also not sure how easy it would be to generate this algorithm. Separate image generation: Perhaps create a PHP file that uses imagemagick or something similar to dynamically generate a .png file in a similar method to the above, and then link to the icon using the URI "domain.tld/imagegen.php?magnitude=magvalue&azimuth=azmvalue". Issue: Still have the problem of actually writing the algorithm for image generation. So, the question: has anyone else come up with solutions for programmatic vector (rather than merely arrow) generation?

  • Subversion error: Repository moved permanently to please relocate

    - by Bart S.
    I've set up subversion and apache on my server. If I browse to it through my webbrowser it works fine (http://svn.host.com/reposname). However, if I do a checkout on my machine I get the following error: Command: Checkout from http://svn.host.com/reposname, revision HEAD, Fully recursive, Externals included Error: Repository moved permanently to 'http://svn.host.com/reposname/'; please relocate I checked apache's error log, but it doesn't say anything. My repositories are stored under: /var/www/svn/repos/ My website is stored under: /var/www/vhosts/x/... Here's the conf file for the subdomain: <Location /> Options +indexes DAV svn SVNParentPath /var/www/svn/repos/ AuthType Basic AuthName "Authorization Realm" AuthUserFile /var/www/svn/auth/svn.htpasswd Require valid-user </Location> Authentication works fine. Does anyone know what might be causing this?

  • How to copy a 200GB file faster?

    - by RainDoctor
    I got a 200GB .tgz file on server A(RHEL 5.2). I wanna transfer that file to server B (RHEL 5.3). Server B is on ESXi 4 Update1. I gave 10GB to that Server B VM, with 4 vCPUs. Both Server A and Server B are connected with an ethernet cable with local IP addies (no switch involved) scp gives me about 3Mbps. Is there a way to get 400Mbps?

  • Creating yum repo

    - by luckytaxi
    I followed this link on how to create my own yum repository for base install and update purposes. If you notice, why would I need a 5 folder on top of 5.4? My installation at the moment is all 5.4, so when I ran "yum update" it wanted to go to http://domain.com/5/... instead of picking up the 5.4 directory. Is 5 basically 5.4 w/ the most updated packages for that tree? meaning, if 5.5 comes out, 5 would be the latest and greatest and if I wanted to track 5.4, I would still need a 5.4 folder to track changes with?

  • Is it possible to use some form of code for example in PUTTY to execute a task which is done Remote

    - by xnxmx
    Basically, Every morning at 6:00AM I have to do login to remote desktop, open a program, and click on a few things to make reservations before anyone else does. I want to know if there is any other way that this can be done by simply turning it into some form of a code and executing it instead of manually doing it. Of course, time is precious here and the task needs to be done at the same pace if not faster. Thanks!!!
