  • Framework for Everything - Where to begin? [Longer post]

    - by SquaredSoft
    Back story of this question, feel free to skip down for the specific question Hello, I've been very interested in the idea of abstract programming the last few years. I've made about 30 attempts at creating a piece of software that is capable of almost anything you throw at it. I've undertook some attempts at this that have taken upwards of a year, while getting close, never releasing it beyond my compiler. This has been something I've always tried wrapping my head around, and something is always missing. With the title, I'm sure you're assuming, "Yes of course you noob! You can't account for everything!" To which I have to reply, "Why not?" To give you some background into what I'm talking about, this all started with doing maybe a shade of gray hat SEO software. I found myself constantly having to create similar, but slightly different sets of code. I've gone through as many iterations of way to communicate on http as the universe has particles. "How many times am I going to have to write this multi-threaded class?" is something I found myself asking a lot. Sure, I could create a class library, and just work with that, but I always felt I could optimize what I had, which often was a large undertaking and typically involved frequent use of the CRTL+A keyboard shortcut, mixed with the delete button. It dawned on me that it was time to invest in a plugin system. This would allow me to simply add snippets of code. as time went on, and I could subversion stuff out, and distribute small chunks of code, rather than something that encompasses only a specific function or design. This comes with its own complexity, of course, and by the time I had finished the software scope for this addition, it hit me that I would want to add to everything in the software, not just a new http method, or automation code for a specific website. Great, we're getting more abstract. However, the software that I have in my mind comes down to a quite a few questions regarding its execution. I have to have some parameters to what I am going to do. After writing what the perfect software would do in my mind, I came up with this as a list of requirements: Should be able to use networking A "Macro" or "Expression system" which would allow people to do something like : =First(=ParseToList(=GetUrl("http://www.google.com?q=helloworld!"), Template.Google)) Multithreaded Able to add UI elements through some type of XML -- People can make their own addons etc. Can use third party API through the plugins, such as Microsoft CRM, Exchange, etc. This would allow the software to essentially be used for everything. Really, any task you wish to automate, in a simple way. Making the UI was as also extremely hard. How do you do all of this? Its very difficult. So my question: With so many attempts at this, I'm out of ideas how to successfully complete this. I have a very specific idea in my mind, but I keep failing to execute it. I'm a self taught programmer. I've been doing it for years, and work professionally in it, but I've never encountered something that would be as complex and in-depth as a system which essentially does everything. Where would you start? What are the best practices for design? How can I avoid constantly having to go back and optimize my software. What can I do to generalize this and draw everything out to completion. These are things I struggle with. P.s., I'm using c# as my main language. I feel like in this example, I might be hitting the outer limit of the language, although, I don't know if that is the case, or if I'm just a bad programmer. Thanks for your time.

  • Unable to "Run on Server" a webapp from Eclipse

    When running my WebApp project from Eclipse most of times it run correctly. But if by mistake to stop server, I kill it in "Console" view on instead of "Stop" Server from "Servers" View.

  • Java jasper report NullPointerException

    - by William Welch
    I am new to Java and I am running into this issue that I can't figure out. I inherited this project and I have the following code in one of my scriptlets: DefaultLogger.logMessage("DEBUG path: "+ reportFile.getPath()); DefaultLogger.logMessage("DEBUG parameters: "+ parameters); DefaultLogger.logMessage("DEBUG jr: "+ jr); bytes = JasperRunManager.runReportToPdf(reportFile.getPath(), parameters, jr); And I am getting the following results (the fourth line there is line 287 in FootwearReportsServlet.doGet): DEBUG path: C:\Development\JavaWorkspaces\Workspace1\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\RSLDevelopmentStandard\reports\templates\footwear\RslFootwearReport.jasper DEBUG parameters: {class_list_subreport=net.sf.jasperreports.engine.JasperReport@b07af1, signature_path=images/logo_reports.jpg, submission_id=20070213154168780, test_results_subreport=net.sf.jasperreports.engine.JasperReport@5795ce, logo_path=images/logos_3.gif, report_connection_secondary=com.mysql.jdbc.JDBC4Connection@2c39d2, testing_packages_subreport=net.sf.jasperreports.engine.JasperReport@1883d5f, signature_path2=images/logo_reports.jpg, tpid_subreport=net.sf.jasperreports.engine.JasperReport@17531fd, first_page_subreport=net.sf.jasperreports.engine.JasperReport@12504e0} DEBUG jr: net.sf.jasperreports.engine.data.JRMapCollectionDataSource@1630eb6 Apr 29, 2010 4:15:13 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet FootwearReportsServlet threw exception java.lang.NullPointerException at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:89) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:601) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:517) at net.sf.jasperreports.engine.JasperRunManager.runReportToPdf(JasperRunManager.java:385) at com.rsl.reports.FootwearReportsServlet.doGet(FootwearReportsServlet.java:287) at javax.servlet.http.HttpServlet.service(HttpServlet.java:617) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Unknown Source) What I can't figure out is where the null reference is. From the debug lines I can see that each parameter has a value. Could it be referring to a bad path to one of the images? Any ideas? For some reason my server won't start in debug mode in Eclipse so I am having trouble figuring this out.

  • How to troubleshoot errors with TeamCity

    - by Tomas Lycken
    I'm following this guide to set up a small environment for source control and automated builds - mostly for learning what it is and how it works, but also for using in those of my hobby projects that I believe will actually be useful some day. However, at the step where he commits and builds, I fail to get a success status in the TeamCity history log. I keep getting the error described in the stack trace below. I have verified with Windows Explorer that the solution file it can't find is actually there, so I really don't know what to do. How do I fix/troubleshoot this?

  • Greasemonkey @require jQuery not working "Component not available"

    - by Greg K
    I've seen the other question on here about loading jQuery in a Greasemonkey. Having tried that method, with this require statement inside my ==UserScript== tags: // @require http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js I still get the following error message in Firefox's error console: Error: Component is not available Source File: file:///Users/greg/Library/Application%20Support/ Firefox/Profiles/xo9xhovo.default/gm_scripts/myscript/jquerymin.js Line: 36 This stops my greasemonkey code from running. I've made sure I included the @require for jQuery and saved my js file before installing it, as required files are only loaded on installation. Code: // ==UserScript== // @name My Script // @namespace http://www.google.com // @description My test script // @include http://www.google.com // @require http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js // ==/UserScript== GM_log("Hello"); I have Greasemonkey 0.8.20091209.4 installed on Firefox 3.5.7 on my Macbook Pro, Leopard (10.5.8). I've cleared my cache (except cookies) and have disabled all other plugins except Flashblock 1.5.11.2, Web Developer 1.1.8 and Adblock Plus 1.1.3. My config.xml with my Greasemonkey script installed: <UserScriptConfig> <Script filename="myscript.user.js" name="My Script" namespace="http://www.google.com" description="My test script" enabled="true" basedir="myscript"> <Include>http://www.google.com</Include> <Require filename="jquerymin.js"/> </Script> I can see jquerymin.js sat in the gm_scripts/myscript/ directory. Additionally, is it common for this error to occur in the console when installing a Greasemonkey script?

    Because of transitive dependencies, my wars are getting populated by xml-apis, xerces jars. I tried following the instructions on the reference page for maven-war-plugin but it is not working. <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <configuration> <packagingExcludes>WEB-INF/lib/xalan-2.6.0.jar,WEB-INF/lib/xercesImpl-2.6.2.jar,WEB-INF/lib/xml-apis-1.0.b2.jar,WEB-INF/lib/xmlParserAPIs-2.6.2.jar</packagingExcludes> <webXml>${basedir}/src/main/webapp/WEB-INF/web.xml</webXml> <warName>project1</warName> <warSourceDirectory>src/main/webapp</warSourceDirectory> </configuration> </plugin> What am I doing wrong ?

  • SQL Server Management Studio – tips for improving the TSQL coding process

    - by kristof
    I used to work in a place where a common practice was to use Pair Programming. I remember how many small things we could learn from each other when working together on the code. Picking up new shortcuts, code snippets etc. with time significantly improved our efficiency of writing code. Since I started working with SQL Server I have been left on my own. The best habits I would normally pick from working together with other people which I cannot do now. So here is the question: What are you tips on efficiently writing TSQL code using SQL Server Management Studio? Please keep the tips to 2 – 3 things/shortcuts that you think improve you speed of coding Please stay within the scope of TSQL and SQL Server Management Studio 2005/2008 If the feature is specific to the version of Management Studio please indicate: e.g. “Works with SQL Server 2008 only" Thanks EDIT: I am afraid that I could have been misunderstood by some of you. I am not looking for tips for writing efficient TSQL code but rather for advice on how to efficiently use Management Studio to speed up the coding process itself. The type of answers that I am looking for are: use of templates, keyboard-shortcuts, use of IntelliSense plugins etc. Basically those little things that make the coding experience a bit more efficient and pleasant. Thanks again

  • jquery load and tinymce gives me a "g.win.document is null" on subsequent loads

    - by Patrice Peyre
    So... very excited as first post on stackoverflow I have this page, clicking a button will call editIEPProgram(). editIEPProgram counts how many specific divs exists, adds another div, loads it with html from '/content/mentoring/iep_program.php' and then calls $("textarea.tinymce").tinymce to add a rich text editor to the newly added text boxes. It finally adds a tab which handles the new stuff and bob is your uncle. It ALMOST works. Clicking the button the first adds everything and everything woks, on the second and subsequent click, everything is added but the tinymce fails to initiate (I guess) and gives me "g.win.document is null". I have been on it for some time now and losing all my sanity. please, help.me. function editIEPProgram(){ var index = $("div[id^=iep_program]").size(); var target_div = "iep_program_"+index; $("#program_container") .append( $("<div></div>") .attr("id", target_div) .addClass("no_overflow_control") ); $("#"+target_div).load ( "/content/mentoring/iep_program.php", {index:index}, function() { $("textarea.tinymce").tinymce({ script_url: "/scripts/tiny_mce.js",height:"60", theme:"advanced",skin:"o2k7",skin_variant : "silver", plugins : "spellchecker,advlist,preview,pagebreak,style,layer,save,advhr,advimage,advlink,searchreplace,paste,noneditable,visualchars,nonbreaking,xhtmlxtras", theme_advanced_buttons1 : "spellchecker,|,bold,italic,underline,strikethrough,|,formatselect,|,forecolor,backcolor,|,bullist,numlist,|,outdent,indent,|,undo,redo,|,link,unlink,image,cleanup,preview", theme_advanced_buttons2 : "", theme_advanced_buttons3 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", content_css : "/css/main.css" }); }); $("#tab_container") .tabs("add", "#"+target_div,"New program") .tabs("select", $("#tab_container").tabs("length")-1); }

  • Fluent NHibernate, dynamically change Table of mapping?

    - by Steffen
    Hello, with fluent nhibernate, is there a way to dynamically switch the table of a mapping at runtime? For example: public class XYClassMap : ClassMap<XY> { public XYClassMap( ) { Table("XYTable"); Id(d => d.Id).GeneratedBy.Identity(); Map(d => d.Value); (...) Given that there are multiple plugins, each of them uses this one class, but they need to work with different tables. I am looking for something like this: public class XY { public string Tablename {get; set;} } public class XYClassMap : ClassMap<XY> { public XYClassMap( ) { Table(Tablename); Id(d => d.Id).GeneratedBy.Identity(); Map(d => d.Value); (...) So every action method could work with the same class and only would need to set this one property "Tablename". Thanks for any help, Steffen

  • Why is it so difficult to get a working IDE for Scala?

    - by Alex R
    I recently gave up trying to use Scala in Eclipse (basic stuff like completion doesn't work). So now I'm trying IntelliJ. I'm not getting very far. This was the original error. See below for update: Scala signature Predef has wrong version Expected 5.0 found: 4.1 in .... scala-library.jar I tried both versions 2.7.6 and 2.8 RC1 of scala-*.jar, the result was the same. JDK is 1.6.u20. UPDATE Today I uninstalled IntelliJ 9.0.1, and installed 9.0.2 Early Availability, with the 4/14 stable version of the Scala plug-in. Then I setup a project from scratch through the wizards: new project from scratch JDK is 1.6.u20 accept the default (project) instead of global / module accept the download of Scala 2.8.0beta1 into project's lib folder Created a new class: object hello { def main(args: Array[String]) { println("hello: " + args); } } For my efforts, I now have a brand-new error :) Here it is: Scalac internal error: class java.lang.ClassNotFoundException [java.net.URLClassLoader$1.run(URLClassLoader.java:202), java.security.AccessController.doPrivileged(Native Method), java.net.URLClassLoader.findClass(URLClassLoader.java:190), java.lang.ClassLoader.loadClass(ClassLoader.java:307), sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301), java.lang.ClassLoader.loadClass(ClassLoader.java:248), java.lang.Class.forName0(Native Method), java.lang.Class.forName(Class.java:169), org.jetbrains.plugins.scala.compiler.rt.ScalacRunner.main(ScalacRunner.java:72)] Thanks

  • jQuery AJAX request (Rails 3) gets redirected and returns empty message body (only with SSL)!

    - by elsurudo
    I'm trying to do a manual jQuery AJAX request the following way: $("#user_plan_id").change(function() { $("#plan_container").load('/plans/' + this.value); }); I have the "rails.js" file included in my header, and a "<%= csrf_meta_tag %". I see from my log that the request IS getting to the server (although without the authenticity token... does rails.js even do this?), but the response is a 302 (Found) rather than 200, and no data actually gets rendered. Any ideas? Edit: I now see that the first request redirects, and the proper partial gets rendered on the redirect. However, the 2nd response's body (on the client-side) is still empty. I'm guessing jQuery uses the first response and doesn't have a listener set up for the redirect. How do I get around this? Also, another note: the page doing the requesting is an HTTPS page. Here is what my log says: Started GET "/plans/221168073" for 127.0.0.1 at Tue Jun 15 01:24:06 -0400 2010 Processing by PlansController#show as HTML Parameters: {"id"=>"221168073"} DEPRECATION WARNING: Using #request_uri is deprecated. Use fullpath instead.

I still have no idea why, though. So I suppose my question is: what is the workaround?

    - by hoffmandirt
    I am using Eclipse 3.5 SR2 for Java EE developers. Each time I press control+C or control+V for the first time after I open a file I get an error. After I close the error, I can successfully copy and paste. The error message made me believe that it was related to the Mylyn plugin, but I uninstalled it and still no difference. Has anyone else experience this problem? I also have the subclipse, adobe flex builder, and maven plugins installed. The 'org.eclipse.mylyn.tasks.ui.hyperlinks.detectors.url' extension from plug-in 'org.eclipse.mylyn.tasks.ui' to the 'org.eclipse.ui.workbench.texteditor.hyperlinkDetectors' extension point failed to load the hyperlink detector. Plug-in org.eclipse.mylyn.tasks.ui was unable to load class org.eclipse.mylyn.internal.tasks.ui.editors.TaskUrlHyperlinkDetector. An error occurred while automatically activating bundle org.eclipse.mylyn.tasks.ui (520). The 'org.eclipse.mylyn.java.hyperlink.detector.stack' extension from plug-in 'org.eclipse.mylyn.java.tasks' to the 'org.eclipse.ui.workbench.texteditor.hyperlinkDetectors' extension point failed to load the hyperlink detector.

  • Maven WTP webapp with maven-eclipse-plugin but without m2eclipse

    - by chrsk
    I use the eclipse:eclipse goal to generate an Eclipse Project environment. The deployment works fine. The goal creates the var classpath entries for all needed dependencies. With m2eclipse there was the Maven Container which defines an export folder which was WEB-INF/lib for me. But i don't want to rely on m2eclipse so i don't want to use it anymore. the class path entries which are generated by eclipse:eclipse goal don't have such a export folder. While booting the servlet container with WTP it publishes all resources and classes except the libraries to the context. Whats missing to publish the needed libs, or isn't that possible without m2eclipse integration?

  • Using Jquery UI Tab control in ASP.NET MVC

    - by mike3333
    I am new to jquery and am trying out UI plugins. For some reason this following code does not work, in the sense, it does not render the tabs and it's just a bunch of text. But when I copy the page source and paste it in the html page, and put it in the views folder, everything looks great, so , I assume all the js paths are good. Any ideas? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Details $(document).ready(function() { $("#tabs").tabs(); }); <div id="tabs"> <ul> <li><a href="#tabs-1">Text 1</a></li> <li><a href="#tabs-2">Text 2</a></li> <li><a href="#tabs-3">Text 3</a></li> </ul> <div id="tabs-1"> <div>tab1 content - adsfadfadsf</div> </div> <div id="tabs-2"> <div>tab 2 content -adfadfadf </div> </div> <div id="tabs-3"> <div>tab 3 content -adfadfadfadf</div> </div> </div> </div>

  • TinyMCE + jQuery + custom plugin = tinymce is undefined?

    - by user368691
    The problem occurs when I try to create small plugin to allow me toggle on and off WYSIWYG on all textareas in the website. //$('form.default textarea').each(function(){ // console.log( $('<a href="#">Enable WYSIWYG editor</a>').insertAfter('form.default textarea').prev('textarea.wysiwyg').tinymce().hide() ); //}); The full (a bit simplified) code looks like this: $('textarea.wysiwyg').tinymce({ skin : 'cirkuit', theme : 'advanced', plugins : 'pagebreak,style,layer,advlink,inlinepopups,contextmenu,paste,directionality,noneditable,nonbreaking,xhtmlxtras,template', // Theme options theme_advanced_buttons1 : 'formatselect,fontsizeselect,forecolor,|,bold,italic,strikethrough,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,|,link,unlink,|,image,|,code,paste,pastetext,pasteword,removeformat,|,backcolor,|,underline,justifyfull,sup,|,outdent,indent,|,hr,charmap,|,undo,redo', theme_advanced_buttons2 : '', theme_advanced_buttons3 : '', theme_advanced_toolbar_location : 'top', theme_advanced_toolbar_align : 'left', theme_advanced_statusbar_location: 'bottom', theme_advanced_resizing : true, theme_advanced_resize_horizontal : false, height : 500, theme_advanced_resizing_min_height : 500, document_base_url : 'http://static.<?=$settings['system_host']?>/' }); $('textarea.wysiwyg').each(function() { $(this).tinymce().hide(); }); What is the error? FireBug says that tinymce() in undefined; this message occurs in each() loop. Thus, tinymce() is actually initialized. I am really lost towards, what could be causing this.

  • Understanding asp.net mvc IView and IView.Render

    - by Harpreet
    I'm trying to devise a method of doing VERY simple asp.net mvc plugins but mostly I'm trying to understand how view rendering works. I've distilled my problem down to this public class CustomView : IView { public void Render(ViewContext viewContext, TextWriter writer) { writer.Write( /* string to render */); } } Now, within that write method I can render any string to the view but when I put a line of code in there wrapped with <% % it renders the code to the view literally rather than parsing it and executing it. I've tried adding things like <% @Page ... to the beginning of the string and it just renders that literally as well. Among many attempts I'm currently calling it this way within a controller action: ... CustomView customView = new CustomView(); ViewResult result = new ViewResult(); result.View = customView; result.ViewName = "Index.aspx"; result.MasterName = ""; return result; What am I missing or doing wrong that this won't work? The ViewResult seems to have the WebFormViewEngine in its ViewEngines collection. I just want to understand this and after stripping it down to what I think should be the minimum it doesn't behave as I think it should. I'm guessing some other part of the machinery is involved/missing but I can't figure out what.

  • FileNotFoundException, altough the XML file should be deployed

    - by Bernhard V
    Hi, I've got problems starting my WAR application on a local JBoss. After two other EARs are deployed and the TomcatDeployer begins deploying the WAR, I'm getting the following error message: 2010-04-28 10:01:56,605 ERROR [org.jboss.ejb.plugins.LogInterceptor] [] [main] EJBException in method: public abstract at.sozvers.stp.zpv.ejb.lea.rwsuc.EJBLeaRegelwerkSuchenRemote at.sozvers.stp.zpv.ejb.lea.rwsuc.EJBLeaRegelwerkSuchenHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException, causedBy: javax.ejb.EJBException: org.springframework.beans.factory.access.BootstrapException: Unable to initialize group definition.

And at least I get a message that the deployment of the EAR has been successful. I also looked into the JAR with my file archiver and the ContextBasic.xml is indeed there at the right place. Is there a way for me to get sure that the JAR, not the EAR as a whole, is really deployed to the JBoss? I'm already starting to lose my head about this issue. Thank you. Bernhard

  • jQuery datepicker validation message issue

    - by Abhishek
    Hi, I'm using the jquery datepicker plugin at http://plugins.jquery.com/project/datepick with the datepicker validation plugin. <script id="frmValidation" type="text/javascript"> $(document).ready(function(){ var validator = $("#frmTest").validate({ rules:{ fname: "required", dobPicker: "required" }, messages:{ fname: "Please enter a name", dobPicker: "Select a date" }, }); $('#dobPicker').datepick(); $.datepick.setDefaults({showOn: 'both', dateFormat: 'dd-mm-yy', yearRange:'1900:2010'}); }); </script> And the body of the document is as follows : <form id="frmTest" action="" method="post"> <div id="error-list"></div> <div class="form-row"> <span class="label"><label for="fname">Name</label></span> <input type="text" name="fname" /> </div> <div class="form-row"> <span class="label"><label for="dobPicker">DOB</label></span> <input type="text" id="dobPicker" name="dobPicker" style="margin-left: 4px;"/> </div> <div class="form-row"> <input type="submit" name="submit" value="submit"/> </div> </form> The form validates the first time but the error message for the datepicker does not disappear immediately a date is selected.. however it goes away if the date is selected the second time. Any help to make it go the first time a date is selected will be appreciated

  • Jquery cookie plugin - conditional content determined by cookie being set

    - by Dave
    Hello I have a sign up form that is displayed to all new site visitors. If a user fills out the form, the next time they visit the site, I would like to display a "welcome back" message where the form would usually sit. I am trying to do this via the jquery cookie plugin (http://plugins.jquery.com/project/Cookie). My form would look like this: <div id="sign_up_form_wrapper"><form id="sign_up" action="" method="POST" name="form"> <input type="checkbox" name="checkbox" id="checkbox" value="1">&nbsp; I accept the terms and conditions</a> <br /><br /><input type="submit" value="ENTER"> </form></div> And I am setting my cookie here: <script type="text/javascript" language="javascript"> $().ready(function() { $('#sign_upm').submit(function(e) { e.preventDefault(); if ($('#sign_up input[name=checkbox]').is(':checked')) { $.cookie('agreed_to_terms', '1', { path: '/', expires: 999999 }); } }); }); </script> That will set the cookie when a user has checked the box, but now I need to do somehting like this: if the cookie has been set, do this: <div id="sign_up_form_wrapper"> <p>Welcome back, John</p> </div> otherwise do this: <div id="sign_up_form_wrapper"> <!-- full form code here --> </div> Any ideas or pointers would be very appreciated, thanks.
