  • Is there a jquery List plugin that will auto-sort items and has robust add/remove methods?

    - by Breadtruck
    I have been googling for hours looking for something to handle my situation. I am not skilled enough to write my own jquery plugin ..YET!! The plugin should auto-sort the list, not as important as being able to add/remove items from the list easily. Themeroller capable would be a plus. I would basically use anything as long as I could add a item to the list (or any other container for that matter), item is coming from a modal popup that is using ajax to search for the item. Once the item is found I want to click that item and have it added to the list and it would put it into the correct order based on alphabetic sort. I think where I am losing sight is the complexity of the item and needing to have the item contain: The name of the item a hidden value, [the int id of the item], one or two checkboxes for turning on/off a feature for that item. I am really open to any ideas, suggestions on a better process, or a pointer to a plugin that might get me close.

  • Generic Http Module

    - by MartinF
    The problem I am trying to make a generic http module in asp.net C# for handling roles defined by an enum which i want to be able to change by a generic parameter. This will make it possible to use the generic module with any kind of enum defined for each project. The module hooks into the Authenticate event of the FormsAuthenticationModule, and is called on each request to the website. The module exposes public events which could be defined in the global.asax. But i cant seem to figure out how to make the generic http module work like a non generic module. There is 3 main problems. I cant register the generic http module in the web.config like any other module as i cant specify the generic parameter, or is possible somehow ? The way to solve that as far as i can figure out is to create a non-generic http module that intializes the generic HttpModule (the generic parameter is defined in a custom section for the module in the web.config). But that introduces the next problem. I cant find out how to make the public events exposed by the generic module available to hook into through the global.asax as you would normally do with a non-generic module by just making a public method with the name like ModuleClassName_PublicEventName. The init() method on the http module gets an reference to the HttpApplication object created in the global.asax. I dont know if it somehow could be possible with reflection to search for the methods and if they are defined in the global.asax (HttpApplication super class) hook them up with the correct event handler ? or if any methods on the HttpApplication object can be used? How would i store and later get a reference to the generic module created in the non-generic module ? I can get the non-generic module with HttpContext.Current.ApplicationInstance.Modules.Get("TheModule"); but is there any way i can store a reference to the generic module in the non-generic module (cant figure out how it should be possible), or store it somewhere else so i can always get it? If I can get a reference to the generic module from the global.asax etc. the events mentioned in nr. 2 can be manually wired to the methods. Thoughts and other possible solutions Instead of registering the module in the web.config it can be manually initialized by overridding the Init method of the HttpApplication and calling the Init method on the module. But that will introduce some new problems. The module will no longer be added to the the ModulesCollection. So I will need to store a reference somewhere else. This could be done with a property in the global.asax, and by implementing an interface, or by creating an generic abstract base type inheriting from HttpApplication, that the global.asax could inherit from. In the generic abstract base type i could also override the init method. It will still not automatically hook up methods in the global.asax with events in the generic module. If it is possible with reflection to search for defined methods in the super type of the HttpApplication it could be automatically done that way. But i can wire the methods in the global.asax with the events in the generic module manually either in the Init method or anywhere else by getting reference to the generic module. It doesnst really need to implement the IHttpModule interface if i choose to manually initalize the generic module. I could just aswell move all the code to the abstract base type inheriting from the HttpApplication. I would prefer to register the module simply by defining it in the web.config as it will be the easiest and most natural / logical solution. Also it would be great if it could be kept as a HttpModule instead of having to define a an abstract base type inheriting from HttpApplication, else it will be more thighed up and not as loose and plugable as i wanted it to be (but maybe it is not possible). Another alternative would be to make it all static. As far as i can figure out i would have to somehow make sure that only one method can be added to the public static events, so it wont add a reference each time a new instance of the global.asax is created. I simply cant find out what is the best solution. I have been messing around with this and thinking about it for days now. Maybe there is an option that i havent thought of ? Hope anyone out there can help me.

  • How to use Maven2 with Apache Sling?

    - by Jerome Baum
    Google doesn't help, neither does a stackoverflow.com search, and browsing through Apache Sling documentation doesn't show any solution so here goes: How can I best use Maven2 with Apache Sling? Basically as far as I see the entire application code will need to be placed in the JCR repository, but I need it versioned. There is some documentation about OSGi bundles that could contain resources, but isn't it kind of overkill to create a bundle with a bunch of Java code to talk to Sling when all I want to do is load some files to corresponding URLs? What I was hoping for is something like jetty:run that will automatically deploy a WAR into a new Jetty instance. Ideally the goal for Sling would run Sling and then load the specified content -- is there some Maven2 plugin for this right now? Or is the bundle-based solution the "canonical" way of doing this?

  • algorithm to use to return a specific range of nodes in a directed graph

    - by GatesReign
    I have a class Graph with two lists types namely nodes and edges I have a function List<int> GetNodesInRange(Graph graph, int Range) when I get these parameters I need an algorithm that will go through the graph and return the list of nodes only as deep (the level) as the range. The algorithm should be able to accommodate large number of nodes and large ranges. Atop this, should I use a similar function List<int> GetNodesInRange(Graph graph, int Range, int selected) I want to be able to search outwards from it, to the number of nodes outwards (range) specified. So in the first function, I expect it to return the nodes placed in the blue box. The other function, if I pass the nodes as in the graph with a range of 1 and it starts at node 5, I want it to return the list of nodes that satisfy this criteria (placed in the orange box)

  • Where can I download a free, text-rich dataset?

    - by blee
    I want to do a bit of lightweight testing and bench-marking for full-text search, so the dataset should have the qualities: 10,000 - 100,000 records. good dispersion of English words. In CSV or Excel format--i.e. I don't want to access it via API. Something like books or movies with title and description fields would be perfect. I browsed the UCI Machine Learning Repo, but it was too number-oriented. Thanks!

  • Setup GIT Server with Msysgit on Windows

    - by Tom
    Hi Guys, My friends and I are trying to setup GIT for windows using this tutorial but we just keep running into problems. I know many of you guys on this site are GIT gurus - so I was wondering whether anyone would be able to help us (and I am sure 100s of other Windows Devs who want to use GIT) write a "Setup GIT Server" guide for windows using Msysgit ? There is a comment on the guide above suggesting it cant be done with Msysgit because gitosis requires the use of an SSH Server and Bash ? Would really appreciate it if someone could do a step by step guide as there is not one available (we've search for hours)? Install Mysisgit ? Thx

  • will_paginate undefined method error - Ruby on Rails

I followed all the instructions listed with the plugin and I am getting an 'undefined method `paginate' for' error.

  • Hybrid static/dynamic Google Map

    - by jonathanconway
    Ever noticed that when you go to maps.google.com and do a search (say, car wash), it renders a lot of results (represented by small circles) and a few prominent ones (seen as regular-size pins)? Notice how quickly it does this? From what I can tell from analyzing this in Firebug, much of this is generated on the server and sent to the client as a static image. However, it's still dynamic. You can still zoom in and out, or click on a result and see a dynamic InfoWindow rendered. Google have made the map quick and smooth using static images, while still making it flexible. Is there a way to do this kind of 'pre-loading' with my own Google Map (implemented with the Google Maps API)?

  • The subscription model behind CSS selectors?

    - by Martin Kristiansen
    With CSS selectors a query string body > h1.span subscribes to a specific type of nodes in the tree. Does anyone know how this is done? Selectors for transformations, how does the browser select the result set? And is there a trick to making it efficient? I imagine there being some sort of hierarchical type-tree for the entire structure to which the nodes subscribe and which is what is used when doing the selector queries — but this is only a guess. Does anyone know the real answer? Or even more interesting, what would be the best way to do dynamic lookups on a tree based on jQuery/CSS search queries?

  • How do I reload .bashrc without logging out and back in?

    - by Jed Daniels
    Hello StackOverflowers, If I make changes to .bashrc, how do I reload it without logging out and back in? I'm embarrassed that I don't know the answer to this question, since I do a fair amount of bash scripting. I'm also couldn't decide if I should post this on ServerFault, but since I do more scripting than sysadmin, I chose StackOverflow; go ahead and move it if you (the community) feel that SF would have been a better choice. Thanks in advance. I'm sure once I hear the answer I'll be saying "doh! I knew that.", but it'll probably be good to have the answer here for other folks like me that should know (or do), but can't remember (I did search before asking, and couldn't find the answer, sorry if this is a repost). --jed

  • A jQuery Plug-in to monitor Html Element CSS Changes

    - by Rick Strahl
    Here's a scenario I've run into on a few occasions: I need to be able to monitor certain CSS properties on an HTML element and know when that CSS element changes. The need for this arose out of wanting to build generic components that could 'attach' themselves to other objects and monitor changes on the ‘parent’ object so the dependent object can adjust itself accordingly. What I wanted to create is a jQuery plug-in that allows me to specify a list of CSS properties to monitor and have a function fire in response to any change to any of those CSS properties. The result are the .watch() and .unwatch() jQuery plug-ins. Here’s a simple example page of this plug-in that demonstrates tracking changes to an element being moved with draggable and closable behavior: http://www.west-wind.com/WestWindWebToolkit/samples/Ajax/jQueryPluginSamples/WatcherPlugin.htm Try it with different browsers – IE and FireFox use the DOM event handlers and Chrome, Safari and Opera use setInterval handlers to manage this behavior. It should work in all of them but all but IE and FireFox will show a bit of lag between the changes in the main element and the shadow. The relevant HTML for this example is this fragment of a main <div> (#notebox) and an element that is to mimic a shadow (#shadow). <div class="containercontent"> <div id="notebox" style="width: 200px; height: 150px;position: absolute; z-index: 20; padding: 20px; background-color: lightsteelblue;"> Go ahead drag me around and close me! </div> <div id="shadow" style="background-color: Gray; z-index: 19;position:absolute;display: none;"> </div> </div> The watcher plug in is then applied to the main <div> and shadow in sync with the following plug-in code: <script type="text/javascript"> $(document).ready(function () { var counter = 0; $("#notebox").watch("top,left,height,width,display,opacity", function (data, i) { var el = $(this); var sh = $("#shadow"); var propChanged = data.props[i]; var valChanged = data.vals[i]; counter++; showStatus("Prop: " + propChanged + " value: " + valChanged + " " + counter); var pos = el.position(); var w = el.outerWidth(); var h = el.outerHeight(); sh.css({ width: w, height: h, left: pos.left + 5, top: pos.top + 5, display: el.css("display"), opacity: el.css("opacity") }); }) .draggable() .closable() .css("left", 10); }); </script> When you run this page as you drag the #notebox element the #shadow element will maintain and stay pinned underneath the #notebox element effectively keeping the shadow attached to the main element. Likewise, if you hide or fadeOut() the #notebox element the shadow will also go away – show the #notebox element and the shadow also re-appears because we are assigning the display property from the parent on the shadow. Note we’re attaching the .watch() plug-in to the #notebox element and have it fire whenever top,left,height,width,opacity or display CSS properties are changed. The passed data element contains a props[] and vals[] array that holds the properties monitored and their current values. An index passed as the second parm tells you which property has changed and what its current value is (propChanged/valChanged in the code above). The rest of the watcher handler code then deals with figuring out the main element’s position and recalculating and setting the shadow’s position using the jQuery .css() function. Note that this is just an example to demonstrate the watch() behavior here – this is not the best way to create a shadow. If you’re interested in a more efficient and cleaner way to handle shadows with a plug-in check out the .shadow() plug-in in ww.jquery.js (code search for fn.shadow) which uses native CSS features when available but falls back to a tracked shadow element on browsers that don’t support it, which is how this watch() plug-in came about in the first place :-) How does it work? The plug-in works by letting the user specify a list of properties to monitor as a comma delimited string and a handler function: el.watch("top,left,height,width,display,opacity", function (data, i) {}, 100, id) You can also specify an interval (if no DOM event monitoring isn’t available in the browser) and an ID that identifies the event handler uniquely. The watch plug-in works by hooking up to DOMAttrModified in FireFox, to onPropertyChanged in Internet Explorer, or by using a timer with setInterval to handle the detection of changes for other browsers. Unfortunately WebKit doesn’t support DOMAttrModified consistently at the moment so Safari and Chrome currently have to use the slower setInterval mechanism. In response to a changed property (or a setInterval timer hit) a JavaScript handler is fired which then runs through all the properties monitored and determines if and which one has changed. The DOM events fire on all property/style changes so the intermediate plug-in handler filters only those hits we’re interested in. If one of our monitored properties has changed the specified event handler function is called along with a data object and an index that identifies the property that’s changed in the data.props/data.vals arrays. The jQuery plugin to implement this functionality looks like this: (function($){ $.fn.watch = function (props, func, interval, id) { /// <summary> /// Allows you to monitor changes in a specific /// CSS property of an element by polling the value. /// when the value changes a function is called. /// The function called is called in the context /// of the selected element (ie. this) /// </summary> /// <param name="prop" type="String">CSS Properties to watch sep. by commas</param> /// <param name="func" type="Function"> /// Function called when the value has changed. /// </param> /// <param name="interval" type="Number"> /// Optional interval for browsers that don't support DOMAttrModified or propertychange events. /// Determines the interval used for setInterval calls. /// </param> /// <param name="id" type="String">A unique ID that identifies this watch instance on this element</param> /// <returns type="jQuery" /> if (!interval) interval = 100; if (!id) id = "_watcher"; return this.each(function () { var _t = this; var el$ = $(this); var fnc = function () { __watcher.call(_t, id) }; var data = { id: id, props: props.split(","), vals: [props.split(",").length], func: func, fnc: fnc, origProps: props, interval: interval, intervalId: null }; // store initial props and values $.each(data.props, function (i) { data.vals[i] = el$.css(data.props[i]); }); el$.data(id, data); hookChange(el$, id, data); }); function hookChange(el$, id, data) { el$.each(function () { var el = $(this); if (typeof (el.get(0).onpropertychange) == "object") el.bind("propertychange." + id, data.fnc); else if ($.browser.mozilla) el.bind("DOMAttrModified." + id, data.fnc); else data.intervalId = setInterval(data.fnc, interval); }); } function __watcher(id) { var el$ = $(this); var w = el$.data(id); if (!w) return; var _t = this; if (!w.func) return; // must unbind or else unwanted recursion may occur el$.unwatch(id); var changed = false; var i = 0; for (i; i < w.props.length; i++) { var newVal = el$.css(w.props[i]); if (w.vals[i] != newVal) { w.vals[i] = newVal; changed = true; break; } } if (changed) w.func.call(_t, w, i); // rebind event hookChange(el$, id, w); } } $.fn.unwatch = function (id) { this.each(function () { var el = $(this); var data = el.data(id); try { if (typeof (this.onpropertychange) == "object") el.unbind("propertychange." + id, data.fnc); else if ($.browser.mozilla) el.unbind("DOMAttrModified." + id, data.fnc); else clearInterval(data.intervalId); } // ignore if element was already unbound catch (e) { } }); return this; } })(jQuery); Note that there’s a corresponding .unwatch() plug-in that can be used to stop monitoring properties. The ID parameter is optional both on watch() and unwatch() – a standard name is used if you don’t specify one, but it’s a good idea to use unique names for each element watched to avoid overlap in event ids especially if you’re monitoring many elements. The syntax is: $.fn.watch = function(props, func, interval, id) props A comma delimited list of CSS style properties that are to be watched for changes. If any of the specified properties changes the function specified in the second parameter is fired. func The function fired in response to a changed styles. Receives this as the element changed and an object parameter that represents the watched properties and their respective values. The first parameter is passed in this structure: { id: watcherId, props: [], vals: [], func: thisFunc, fnc: internalHandler, origProps: strPropertyListOnWatcher }; A second parameter is the index of the changed property so data.props[i] or data.vals[i] gets the property and changed value. interval The interval for setInterval() for those browsers that don't support property watching in the DOM. In milliseconds. id An optional id that identifies this watcher. Required only if multiple watchers might be hooked up to the same element. The default is _watcher if not specified. It’s been a Journey I started building this plug-in about two years ago and had to make many modifications to it in response to changes in jQuery and also in browser behaviors. I think the latest round of changes made should make this plug-in fairly future proof going forward (although I hope there will be better cross-browser change event notifications in the future). One of the big problems I ran into had to do with recursive change notifications – it looks like starting with jQuery 1.44 and later, jQuery internally modifies element properties on some calls to some .css()  property retrievals and things like outerHeight/Width(). In IE this would cause nasty lock up issues at times. In response to this I changed the code to unbind the events when the handler function is called and then rebind when it exits. This also makes user code less prone to stack overflow recursion as you can actually change properties on the base element. It also means though that if you change one of the monitors properties in the handler the watch() handler won’t fire in response – you need to resort to a setTimeout() call instead to force the code to run outside of the handler: $("#notebox") el.watch("top,left,height,width,display,opacity", function (data, i) { var el = $(this); … // this makes el changes work setTimeout(function () { el.css("top", 10) },10); }) Since I’ve built this component I’ve had a lot of good uses for it. The .shadow() fallback functionality is one of them. Resources The watch() plug-in is part of ww.jquery.js and the West Wind West Wind Web Toolkit. You’re free to use this code here or the code from the toolkit.

  • Windows 64-bit registry v.s. 32-bit registry

    - by George2
    Hello everyone, I heard on Windows x64 architecture, in order to support to run both x86 and x64 application, there is two separate/different sets of Windows registry -- one for x86 application to access and the other for x64 application to access? For example, if a COM registers CLSID in the x86 set of registry, then x64 application will never be able to access the COM component by CLSID, because x86/x64 have different sets of registry? So, my question is whether my understanding of the above sample is correct? I also want to get some more documents to learn this topic, about the two different sets of registry on x64 architecture. (I did some search, but not found any valuable information.) thanks in advance, George

  • msysgit bash shell- how to troubleshoot "cannot find command"

    - by Frank Schwieterman
    I need help getting git extensions to run with msysgit. I have had bad luck with extensions git-tfs and git-fetchall, in both cases it is the same problem. The addon will require a file to be placed where git can find it (git-tfs.exe and git-fetchall.sh). I understand this to mean the files need to be in a directory that is in the 'PATH' environment variable. In both cases I get stuck at this point: $ git-diffall bash: git-diffall: command not found or: $ git-tfs bash: git-tfs: command not found When I run echo %PATH% from a regular command shell, it shows my path variable includes the directories where git-diffall and git-tfs are. How can I debug this, or am I missing something? Is there a way within msysgit to verify the command search path is what I expect?

  • Sharepoint and Cross-Site Lookup

    - by Mina Samy
    Hi all I have this scenario I want to build two sharepoint 2007 sites. One for customers info and the other for products and customers orders. Now the problem is that in the second site I need to reference the customers info from the first site but unfortunately sharepoint doesnot provide out of the box cross-site lookup. I did some search and found custom cross-site fields and used one but when I upgraded the site to sharepoint 2010 this custom field was not compatible and the upgrade wizard said it could not be upgraded. so what is the solution for this ? is it to merge the two sites so that I can use the standard lookup feature or is there any workaround for this ? please if any body has faced such a scenario, share the solution with me ? thanks

  • Parsing Wiki XML Dumps ver0.4 just got tough

    - by syed
    Hello, I am trying to parse Wikipedia XML Dump using "Parse-MediaWikiDump-1.0.4" along with "Wikiprep.pl" script. I guess this script works fine with ver0.3 Wiki XML Dumps but not with the latest ver0.4 Dumps. I get the following error. Can't locate object method "page" via package "Parse::MediaWikiDump::Pages" at wikiprep.pl line 390. Also, under the "Parse-MediaWikiDump-1.0.4" documentation @ http://search.cpan.org/~triddle/Parse-MediaWikiDump-1.0.4/lib/Parse/MediaWikiDump/Pages.pm, I read "LIMITATIONS Version 0.4 This class was updated to support version 0.4 dump files from a MediaWiki instance but it does not currently support any of the new information available in those files." Any work arounds would help me get to the next level. Note: one may wonder why cannot we directly use SAX or STAX parser instead, wikipedia dump is a 25GB plus single file, stack/memory issues are obvious. Hence, the above perl script resolves this issue but currently I am stuck with this version problem.

  • Rotating images + content - jQuery or MooTools?

    - by Lenwood
    I've found a feature on two different websites that I'd like to include on one of my web projects, but I can't figure out how they're doing it. I think they're using either jQuery or mootools, but I'm not sure. http://www.x-plane.com/index_desktop.html I'm new here so I don't have the reputation to post the other link, but if you do a Google search for "Andrews Institute of Orthopaedics" its the top result. I'll see if I can answer a few questions to earn my keep. The thing that I like about these is that the images and text (including links) are all rotated together. I've done a few web searches related to cycle, rotate and slide but it's not coming together for me. Can anyone give me a nudge in the right direction?

  • Spatial index for geo coordinates?

    - by Michael Borgwardt
    What kind of data structure could be used for an efficient nearest neighbor search in a large set of geo coordinates? With "regular" spatial index structures like R-Trees that assume planar coordinates, I see two problems (Are there others I have overlooked?): Wraparound at the poles and the International Date Line Distortion of distances near the poles How can these factors be allowed for? I guess the second one could compensated by transforming the coordinates. Can an R-Tree be modified to take wraparound into account? Or are there specialized geo-spatial index structures?

  • yii combining addColumnCondition in CDbCriteria

    - by keeg
    I have a couple of dropdown filters in my GridView, in the search part of my model I have: if ($this->agent_primary != "") { $criteria->addColumnCondition(array('agent_type_id'=>1, 'agent.agent_id'=>$this->agent_primary)); } if ($this->agent_voice != "") { $criteria->addColumnCondition(array('agent_type_id'=>2, 'agent.agent_id'=>$this->agent_voice)); } if ($this->agent_commercial != "") { $criteria->addColumnCondition(array('agent_type_id'=>3, 'agent.agent_id'=>$this->agent_commercial)); } I need to somehow combine this so if someone selects two of the three dropdowns (or all three) they get the correct results, currently the sql has there WHERE in separate brackets for each addColumnCondition: WHERE (condition1a = a AND condition1b = b) AND (condition2a = a AND condition2b = b) instead of WHERE (condition1a = a AND condition1b = b) OR (condition2a = a AND condition2b = b)

  • regex to filter all but whitelisted characters from a multi-language string

    - by jeroen
    I am trying to cleanup a string coming from a search box on a multi-language site. Normally I would use a regex like: $allowed = "-+?!,.;:\w\s"; $txt_search = preg_replace("/[^" . $allowed . "]?(.*?)[^" . $allowed . "]?/iu", "$1", $_GET['txt_search']); and that works fine for English texts. However, now I need to do the same when the texts entered can be in any language (Russian now, Chinese in the future). How can I clean up the string while preserving "normal texts" in the original language? I though about switching to a blacklist (although I´d rather not...) but at this moment the regex just completely destroys all original input.

  • Where to get apache poi port for .net

    - by Nassign
    I would like to know if there is a website where I could download the Apache POI ported for .net? I already found this link in the web http://www.apache.org/~avik/dist/poi-2.5.1-dev-20040708.dll But the version of apache poi now is 3.6, I was wondering if there is a latest version out there? Does the apache foundation support such porting? I already tried to search the apache website too with no avail. As for using Microsoft library, the excel interopt is not that good for concurrent processing like a web backend. If I use the DocumentFormat.OpenXML library, I have a limitation of creating office 2007 document only.

    I have a hard drive that I've been trying to reformat. I tried reformatting it in the windows XP and 7 installers, and in an Ubuntu live cd with gparted. I tried using dd to 'zero' the drive as well with no success. Finally I ran across KillDisk after a search. I tried to zero the disk again with KillDisk and after 8 hours of zeroing I get the following errors in the log: ----------------------------------------Erase Session Begin--------------------------------------- 2010-03-23 19:35:54 Active@ KILLDISK for Windows Build 5.1.39 started Target: WDC WD2500KS-00MJB0 232.9 GB Located on: WDC WD2500KS-00MJB0 (Serial number: WD-WCANK9604799) Erase method: One Pass Zeros (1 pass) Passes: 1 Bad (unwritable) sectors detected from 1701 to 488397167 on Hard Disk 1.

  • doctrine findby relation

    - by iggnition
    I'm having trouble selecting a subset of data with doctrine. I have 3 tables Location Contact Contact_location The contact and location tables hold a name and an id the other table holds only ID's. For instance: Location loc_id: 1 name: detroit Contact contact_id: 1 name: Mike Contact_location loc_id: 1 contact_id: 1 In doctrine there is a many to many relation between the location and contact tables with contact_location as the ref_class. What i want to do is on my location page i want to find all contacts where for instance the loc_id = 1. I tried: $this->installedbases = Doctrine::getTable('contact')->findByloc_id(1); hoping doctrine would see the relation and get it, but it does not. How can i make doctrine search in relevant related tables? I read it can be done using Findby but i find the documentation unclear.
