  • How to use multiple instances of a usercontrol (with jquery) on the same page

    - by Julian
    Hi All, I've been working on an usercontrol with a jquery timer in it. At first I had the jquery within the usercontrol. But when I add 2 of those controls to my page the second usercontrol isn't showing it's data very well. Now I've put the jquery into the mainpage and the usercontrol only uses the id's of the jquery. Here is my usercontrol: <%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %> <style type="text/css"> #mainpanel { width: 145px; height: 123px; } </style> <div id="mainpanel"> <div> test</div> <div id="shortly" style="background-color: #FFFFFF"> </div> <button id="resetButton"> Reset </button> </div> Mainpage: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <%@ Register Src="WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>hoi</title> <script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="Scripts/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script> <link href="Css/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script> <script type="text/javascript" src="Scripts/jquery.countdown.js"></script> <script type="text/javascript"> $(document).ready(function () { $(function() { $("#mainpanel"); }); shortly = new Date(); shortly.setSeconds(shortly.getSeconds() + 5.5); $('#shortly').countdown({ until: shortly, onExpiry: liftOff, layout: '{sn}', }); $('#resetButton').click(function () { $('#mainpanel').effect("highlight", {}, 700 ); $('#shortly').effect("highlight", {}, 700 ); shortly = new Date(); shortly.setSeconds(shortly.getSeconds() + 5.5); $('#shortly').countdown('change', { until: shortly }); }); function liftOff() { // refresh the page window.location = window.location; } }); </script> </head> <body> <uc1:WebUserControl ID="WebUserControl1" runat="server" /> </body> </html> But still my usercontrols are acting weird, now my question is: "How can I make the SAME usercontrols work properly on ONE page?" Both of those use the same jquery code but the buttons etc. should only work within the usercontrol itself.

  • Why isn't my algorithm for find the biggest and smallest inputs working?

    - by Matt Ellen
    I have started a new job, and with it comes a new language: Ironpython. Thankfully a good language :D Before starting I got to grips with Python on the whole, but that was only a week's worth of learning. Now I'm writing actual code. I've been charged with writing an algorithm that finds the best input parameter to collect data with. The basic algorithm is (as I've been instructed): Set the input parameter to a good guess Start collecting data When data is available stop collecting find the highest point If the point before this (i.e. for the previous parameter value) was higher and the point before that was lower then we've found the max otherwise the input parameter is increased by the initial guess. goto 2 If the max is found then the min needs to be found. To do this the algorithm carries on increasing the input, but by 1/10 of the max, until the current point is greater than the previous point and the point before that is also greater. Once the min is found then the algorithm stops. Currently I have a simplified data generator outputting the sin of the input, so that I know that the min value should be PI and the max value should be PI/2 The main Python code looks like this (don't worry, this is just for my edification, I don't write real code like this): import sys sys.path.append(r"F:\Programming Source\C#\PythonHelp\PythonHelp\bin\Debug") import clr clr.AddReferenceToFile("PythonHelpClasses.dll") import PythonHelpClasses from PHCStruct import Helper from System import Math helper = Helper() def run(): b = PythonHelpClasses.Executor() a = PythonHelpClasses.HasAnEvent() b.Input = 0.0 helper.__init__() def AnEventHandler(e): b.Stop() h = helper h.lastLastVal, h.lastVal, h.currentVal = h.lastVal, h.currentVal, e.Number if h.lastLastVal < h.lastVal and h.currentVal < h.lastVal and h.NotPast90: h.NotPast90 = False h.bestInput = h.lastInput inputInc = 0.0 if h.NotPast90: inputInc = Math.PI/10.0 else: inputInc = h.bestInput/10.0 if h.lastLastVal > h.lastVal and h.currentVal > h.lastVal and h.NotPast180: h.NotPast180 = False if h.NotPast180: h.lastInput, b.Input = b.Input, b.Input + inputInc b.Start(a) else: print "Best input:", h.bestInput print "Last input:", h.lastInput b.Stop() a.AnEvent += AnEventHandler b.Start(a) PHCStruct.py: class Helper(): def __init__(self): self.currentVal = 0 self.lastVal = 0 self.lastLastVal = 0 self.NotPast90 = True self.NotPast180 = True self.bestInput = 0 self.lastInput = 0 PythonHelpClasses has two small classes I wrote in C# before I realised how to do it in Ironpython. Executor runs a delegate asynchronously while it's running member is true. The important code: public void Start(HasAnEvent hae) { running = true; RunDelegate r = new RunDelegate(hae.UpdateNumber); AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar = r.BeginInvoke(Input, ac, null); } public void Stop() { running = false; } public void UpdateDone(IAsyncResult ar) { RunDelegate r = (RunDelegate)((AsyncResult)ar).AsyncDelegate; r.EndInvoke(ar); if (running) { AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar2 = r.BeginInvoke(Input, ac, null); } } HasAnEvent has a function that generates the sin of its input and fires an event with that result as its argument. i.e.: public void UpdateNumber(double val) { AnEventArgs e = new AnEventArgs(Math.Sin(val)); System.Threading.Thread.Sleep(1000); if (null != AnEvent) { AnEvent(e); } } The sleep is in there just to slow things down a bit. The problem I am getting is that the algorithm is not coming up with the best input being PI/2 and the final input being PI, but I can't see why. Also the best and final inputs are different each time I run the programme. Can anyone see why? Also when the algorithm terminates the best and final inputs are printed to the screen multiple times, not just once. Can someone explain why?

  • Why does jquery leak memory so badly?

    - by Thomas Lane
    This is kind of a follow-up to a question I posted last week: http://stackoverflow.com/questions/2429056/simple-jquery-ajax-call-leaks-memory-in-ie I love the jquery syntax and all of its nice features, but I've been having trouble with a page that automatically updates table cells via ajax calls leaking memory. So I created two simple test pages for experimenting. Both pages do an ajax call every .1 seconds. After each successful ajax call, a counter is incremented and the DOM is updated. The script stops after 1000 cycles. One uses jquery for both the ajax call and to update the DOM. The other uses the Yahoo API for the ajax and does a document.getElementById(...).innerHTML to update the DOM. The jquery version leaks memory badly. Running in drip (on XP Home with IE7), it starts at 9MB and finishes at about 48MB, with memory growing linearly the whole time. If I comment out the line that updates the DOM, it still finishes at 32MB, suggesting that even simple DOM updates leak a significant amount of memory. The non-jquery version starts and finishes at about 9MB, regardless of whether it updates the DOM. Does anyone have a good explanation of what is causing jquery to leak so badly? Am I missing something obvious? Is there a circular reference that I'm not aware of? Or does jquery just have some serious memory issues? Here is the source for the leaky (jquery) version: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); </script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { $.ajax({ url: '/html/delme.x', type: 'GET', success: incrementCounter }); } function incrementCounter(data) { if (counter<1000) { counter++; $('#counter').text(counter); setTimeout(leakTest,100); } else $('#counter').text('finished.'); } </script> </head> <body> <div>Why is memory usage going up?</div> <div id="counter"></div> </body> </html> And here is the non-leaky version: <html> <head> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/yahoo/yahoo-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/event/event-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/connection/connection_core-min.js"></script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { YAHOO.util.Connect.asyncRequest('GET', '/html/delme.x', {success:incrementCounter}); } function incrementCounter(o) { if (counter<1000) { counter++; document.getElementById('counter').innerHTML = counter; setTimeout(leakTest,100); } else document.getElementById('counter').innerHTML = 'finished.' } </script> </head> <body> <div>Memory usage is stable, right?</div> <div id="counter"></div> </body> </html>

  • jquery with ASP.NET MVC - calling ajax enabled web service

    - by dcp
    This is a bit of a continuation of a previous question. Now I'm trying to make a call to an AJAX enabled web service which I have defined within the ASP.NET MVC application (i.e. the MovieService.svc). But the service is never being called in my getMovies javascript function. This same technique of calling the AJAX web service works ok if I try it in a non ASP.NET MVC application, so it makes me wonder if maybe the ASP MVC routes are interfering with things somehow when it tries to make the AJAX web service call. Do you have any idea why my web service isn't getting called? Code below. <script src="<%= ResolveClientUrl("~/scripts/jquery-1.4.2.min.js") %>" type="text/javascript"></script> <script src="<%= ResolveClientUrl("~/scripts/grid.locale-en.js") %>" type="text/javascript"></script> <script src="<%= ResolveClientUrl("~/scripts/jquery-ui-1.8.1.custom.min.js") %>" type="text/javascript"></script> <script src="<%= ResolveClientUrl("~/scripts/jquery.jqGrid.min.js") %>" type="text/javascript"></script> <script type="text/javascript"> var lastsel2; function successFunction(jsondata) { debugger var thegrid = jQuery("#editgrid"); for (var i = 0; i < jsondata.d.length; i++) { thegrid.addRowData(i + 1, jsondata.d[i]); } } function getMovies() { debugger // ***** the MovieService#GetMovies method never gets called $.ajax({ url: 'MovieService.svc/GetMovies', data: "{}", // For empty input data use "{}", dataType: "json", type: "GET", contentType: "application/json; charset=utf-8", success: successFunction }); } jQuery(document).ready(function() { jQuery("#editgrid").jqGrid({ datatype: getMovies, colNames: ['id', 'Movie Name', 'Directed By', 'Release Date', 'IMDB Rating', 'Plot', 'ImageURL'], colModel: [ { name: 'id', index: 'Id', width: 55, sortable: false, hidden: true, editable: false, editoptions: { readonly: true, size: 10} }, { name: 'Movie Name', index: 'Name', width: 250, editable: true, editoptions: { size: 10} }, { name: 'Directed By', index: 'Director', width: 250, align: 'right', editable: true, editoptions: { size: 10} }, { name: 'Release Date', index: 'ReleaseDate', width: 100, align: 'right', editable: true, editoptions: { size: 10} }, { name: 'IMDB Rating', index: 'IMDBUserRating', width: 100, align: 'right', editable: true, editoptions: { size: 10} }, { name: 'Plot', index: 'Plot', width: 150, hidden: false, editable: true, editoptions: { size: 30} }, { name: 'ImageURL', index: 'ImageURL', width: 55, hidden: true, editable: false, editoptions: { readonly: true, size: 10} } ], pager: jQuery('#pager'), rowNum: 5, rowList: [5, 10, 20], sortname: 'id', sortorder: "desc", height: '100%', width: '100%', viewrecords: true, imgpath: '/Content/jqGridCss/redmond/images', caption: 'Movies from 2008', editurl: '/Home/EditMovieData/', caption: 'Movie List' }); $("#bedata").click(function() { var gr = jQuery("#editgrid").jqGrid('getGridParam', 'selrow'); if (gr != null) jQuery("#editgrid").jqGrid('editGridRow', gr, { height: 280, reloadAfterSubmit: false }); else alert("Hey dork, please select a row"); }); }); </script> <h2> <%= Html.Encode(ViewData["Message"]) %></h2> <p> To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website"> http://asp.net/mvc</a>. </p> <table id="editgrid"> </table> <div id="pager" style="text-align: center;"> </div> <input type="button" id="bedata" value="Edit Selected" /> Here's my RegisterRoutes code: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute("*MovieService.svc*"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } Here's what my MovieService class looks like: namespace jQueryMVC { [ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class MovieService { // Add [WebGet] attribute to use HTTP GET [OperationContract] [WebGet(ResponseFormat = WebMessageFormat.Json)] public IList<Movie> GetMovies() { return Persistence.GetMovies(); } } }

  • Need to hide displayed div when I show others

    - by adrian collins
    I am stuck. I have a page with 3 buttons, the 3 buttons do a couple things - they change the style of a div, and they also show/hide a content div. The changing of the div style works fine, but I am having issues with the content div. If you land on the page and click the "Our Brands" tab, then click the other 2 tabs, it works fine. If you land on the page, and click "What's New" or "About Us" first, then the show/hide does not work correctly - it does not until you actually click on "Our Brands." http://www.adriancollins.net/clients/kennys/ Any help would be appreciated, I am a designer first, a developer about 9000th. Show/Hide Code <script type="text/javascript"> var _hidediv = null; function showdiv(id) { if(_hidediv) _hidediv(); var div = document.getElementById(id); div.style.display = 'block'; _hidediv = function () { div.style.display = 'none'; }; } </script> Tab Divs <div id="brand_button"><a href="#" onClick="showdiv('brands_content'); lower.className='blue';angle.className='blue_angle';return false"><img src="wp-content/uploads/2012/10/brands_button.png"></a></div> <div id="whatsnew_button"><a href="#" onClick="showdiv('new_content');lower.className='black';angle.className='black_angle';return false"><img src="wp-content/uploads/2012/10/whatsnew_button.png"></a></div> <div id="about_button"><a href="#" onClick="showdiv('about_content');lower.className='green';angle.className='green_angle';return false"><img src="wp-content/uploads/2012/10/about_button.png"></a></div> Content Divs <div id="brands_content">Content...</div> <div id="whats_content">Content...</div> <div id="about_content">Content...</div> CSS #brands_content { position: relative; display: block; width: 990px; top: 10px; height: auto; min-height: 800px; margin-left: auto; margin-top: 0px; margin-right: auto; border: 0px; padding: 0px 0px 0px 0px; z-index: 12; } #new_content { position: relative; display: none; width: 990px; top: 10px; height: auto; min-height: 800px; margin-left: auto; margin-top: 0px; margin-right: auto; border: 0px; padding: 0px 0px 0px 0px; z-index: 999; color: #fff; } #about_content { position: relative; display: none; width: 990px; top: 10px; height: auto; min-height: 800px; margin-left: auto; margin-top: 0px; margin-right: auto; border: 0px; padding: 0px 0px 0px 0px; z-index: 999; } Thanks

  • I'm looking for a reliable way to verify T-SQL stored procedures. Anybody got one?

    - by Cory Larson
    Hi all-- We're upgrading from SQL Server 2005 to 2008. Almost every database in the 2005 instance is set to 2000 compatibility mode, but we're jumping to 2008. Our testing is complete, but what we've learned is that we need to get faster at it. I've discovered some stored procedures that either SELECT data from missing tables or try to ORDER BY columns that don't exist. Wrapping the SQL to create the procedures in SET PARSEONLY ON and trapping errors in a try/catch only catches the invalid columns in the ORDER BYs. It does not find the error with the procedure selecting data from the missing table. SSMS 2008's intellisense, however, DOES find the issue, but I can still go ahead and successfully run the ALTER script for the procedure without it complaining. So, why can I even get away with creating a procedure that fails when it runs? Are there any tools out there that can do better than what I've tried? The first tool I found wasn't very useful: DbValidator from CodeProject, but it finds fewer problems than this script I found on SqlServerCentral, which found the invalid column references. ------------------------------------------------------------------------- -- Check Syntax of Database Objects -- Copyrighted work.

  • client-side validation in custom validation attribute - asp.net mvc 4

    - by Giorgos Manoltzas
    I have followed some articles and tutorials over the internet in order to create a custom validation attribute that also supports client-side validation in an asp.net mvc 4 website. This is what i have until now: RequiredIfAttribute.cs [AttributeUsage(AttributeTargets.Property, AllowMultiple = true)] //Added public class RequiredIfAttribute : ValidationAttribute, IClientValidatable { private readonly string condition; private string propertyName; //Added public RequiredIfAttribute(string condition) { this.condition = condition; this.propertyName = propertyName; //Added } protected override ValidationResult IsValid(object value, ValidationContext validationContext) { PropertyInfo propertyInfo = validationContext.ObjectType.GetProperty(this.propertyName); //Added Delegate conditionFunction = CreateExpression(validationContext.ObjectType, _condition); bool conditionMet = (bool)conditionFunction.DynamicInvoke(validationContext.ObjectInstance); if (conditionMet) { if (value == null) { return new ValidationResult(FormatErrorMessage(null)); } } return ValidationResult.Success; } private Delegate CreateExpression(Type objectType, string expression) { LambdaExpression lambdaExpression = System.Linq.Dynamic.DynamicExpression.ParseLambda(objectType, typeof(bool), expression); //Added Delegate function = lambdaExpression.Compile(); return function; } public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { var modelClientValidationRule = new ModelClientValidationRule { ValidationType = "requiredif", ErrorMessage = ErrorMessage //Added }; modelClientValidationRule.ValidationParameters.Add("param", this.propertyName); //Added return new List<ModelClientValidationRule> { modelClientValidationRule }; } } Then i applied this attribute in a property of a class like this [RequiredIf("InAppPurchase == true", "InAppPurchase", ErrorMessage = "Please enter an in app purchase promotional price")] //Added "InAppPurchase" public string InAppPurchasePromotionalPrice { get; set; } public bool InAppPurchase { get; set; } So what i want to do is display an error message that field InAppPurchasePromotionalPrice is required when InAppPurchase field is true (that means checked in the form). The following is the relevant code form the view: <div class="control-group"> <label class="control-label" for="InAppPurchase">Does your app include In App Purchase?</label> <div class="controls"> @Html.CheckBoxFor(o => o.InAppPurchase) @Html.LabelFor(o => o.InAppPurchase, "Yes") </div> </div> <div class="control-group" id="InAppPurchasePromotionalPriceDiv" @(Model.InAppPurchase == true ? Html.Raw("style='display: block;'") : Html.Raw("style='display: none;'"))> <label class="control-label" for="InAppPurchasePromotionalPrice">App Friday Promotional Price for In App Purchase: </label> <div class="controls"> @Html.TextBoxFor(o => o.InAppPurchasePromotionalPrice, new { title = "This should be at the lowest price tier of free or $.99, just for your App Friday date." }) <span class="help-inline"> @Html.ValidationMessageFor(o => o.InAppPurchasePromotionalPrice) </span> </div> </div> This code works perfectly but when i submit the form a full post is requested on the server in order to display the message. So i created JavaScript code to enable client-side validation: requiredif.js (function ($) { $.validator.addMethod('requiredif', function (value, element, params) { /*var inAppPurchase = $('#InAppPurchase').is(':checked'); if (inAppPurchase) { return true; } return false;*/ var isChecked = $(param).is(':checked'); if (isChecked) { return false; } return true; }, ''); $.validator.unobtrusive.adapters.add('requiredif', ['param'], function (options) { options.rules["requiredif"] = '#' + options.params.param; options.messages['requiredif'] = options.message; }); })(jQuery); This is the proposed way in msdn and tutorials i have found Of course i have also inserted the needed scripts in the form: jquery.unobtrusive-ajax.min.js jquery.validate.min.js jquery.validate.unobtrusive.min.js requiredif.js BUT...client side validation still does not work. So could you please help me find what am i missing? Thanks in advance.

  • Need to determine button clicked in a JQuery mobile popup and perform actions based thereon

    - by Clifford
    I am having a problem with a JQM popup. The popup has 3 buttons, and the action taken in the main program depends on which button is clicked.

Controller Action public ActionResult Edit(int id) { var vM = new MyViewModel(); // vM is viewModel return View(vM); } Edit View @using (Html.BeginForm()) { @Html.ValidationSummary(true) ... <span id = "Ship"> @Html.Partial("AJAX_Views/_Ship")</span> _Ship Partial View @model MyProject.ViewModels.MyViewModel <table class="detailtable" style="min-width:398px"> <tr> <th style="padding-left:132px" colspan="2"> <span class="editor-label">Shipping&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Address</span> <span class="editor-label" style="padding-left:55px"> @Ajax.ActionLink("Delete", "SHIPDEL", new AjaxOptions { UpdateTargetId = "Ship", InsertionMode = InsertionMode.Replace, HttpMethod = "Get" })</span> <tr><th style="min-width:152px"><span class="editor-label">Street:</span></th> @Html.HiddenFor(m => m.CmpAdrsSh.Id) @Html.HiddenFor(m => m.CmpAdrsSh.CompPersonId) @Html.HiddenFor(m => m.CmpAdrsSh.IsShip) <td><span class="editor-field">@Html.EditorFor(m => m.CmpAdrsSh.Street) @Html.ValidationMessageFor(m => m.CmpAdrsSh.Street) </span></td></tr> <tr><th><span class="editor-label">City:</span></th> <td><span class="editor-field">@Html.EditorFor(m => m.CmpAdrsSh.City) @Html.ValidationMessageFor(m => m.CmpAdrsSh.City) </span></td></tr> <tr><th><span class="editor-label">State:</span></th> <td><span class="editor-field">@Html.DropDownList("CmpAdrsSh.State", (IEnumerable<SelectListItem>)ViewBag._State) @Html.ValidationMessageFor(m => m.CmpAdrsSh.State) </span></td></tr> <tr><th><span class="editor-label">Zip:</span></th> <td><span class="editor-field">@Html.EditorFor(m => m.CmpAdrsSh.Zip) @Html.ValidationMessageFor(m => m.CmpAdrsSh.Zip) </span></td></tr> _ShipDel Partial View @model MyProject.ViewModels.MyViewModel <table class="detailtable" style="min-width:398px"> <tr> <th style="padding-left:132px" colspan="2"> <span class="editor-label">Shipping&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Address</span> <span class="editor-label" style="padding-left:10px; color:red">Marked for Deletion.</span></th></tr> <tr><td>To not Delete Select Cancel below!</td></tr> @Html.HiddenFor(m => m.CmpAdrsSh.Street) @Html.HiddenFor(m => m.CmpAdrsSh.City) @Html.HiddenFor(m => m.CmpAdrsSh.State) @Html.HiddenFor(m => m.CmpAdrsSh.Zip) Controller PartialViewResult Action public PartialViewResult SHIPDEL() { return PartialView("AJAX_Views/_ShipDel"); } I tried adding this.ModelState to the Action but then the view will not render. I'm guessing I somehow have to pass the model to the SHIPDEL Action first. I couldn't find an @Ajax.ActionLink overload that would allow this. public PartialViewResult SHIPDEL() { return PartialView("AJAX_Views/_ShipDel", this.ModelState); } In the _ShipDel Partial View I need to expose the CmpAdrsSh properties so the model validates in the POST Action. The model is empty at this point. How do I pass the existing vM model into the _ShipDel partial view? Thank you,

  • Having trouble with multiple Jquery libraries

    - by user3716971
    I've seen the posts about the no conflict but I'm not very code savvy and can't figure it out alone. I'm having trouble making two libraries work together. At the top I have the 1.9.1 library which controls a news ticker, and a carousel. Near the bottom there is a library 1.6.1, which controls a Dribbble feed. If I remove 1.6.1 everything but the dribbble feed works, and if I remove the 1.9.1 the dribbble feed is the only thing that works. I uploaded the website for you guys to check out. If you could edit my code to make it work that would be amazing, I don't have much knowledge of jquery. This version has a working dribbble feed at the very bottom http://michaelcullenbenson.com/MichaelCullenBenson.com/index.html and this version has a broken feed and everything else works. http://michaelcullenbenson.com/MichaelCullenBenson.com/index2.html Help would be AMAZING as the dribbble feed is the last element I'm trying to finish on my homepage and I'll be able to move on. <script type="text/javascript" src="js/jquery-1.9.1.min.js"></script> <script type="text/javascript" src="js/jquery.innerfade.js"></script> <script type="text/javascript"> $(document).ready( function(){ $('#news').innerfade({ animationtype: 'slide', speed: 600, timeout: 6000, type: 'random', containerheight: '1em' }); }); </script> <!-- Include all compiled plugins (below), or include individual files as needed --> <script src="utilcarousel-files/utilcarousel/jquery.utilcarousel.min.js"></script> <script src="utilcarousel-files/magnific-popup/jquery.magnific-popup.js"></script> <script src="js/responsive-nav.js"></script> <script> $(function() { $('#fullwidth').utilCarousel({ breakPoints : [[600, 1], [800, 2], [1000, 3], [1300, 4],], mouseWheel : false, rewind : true, autoPlay : true, pagination : false }); $('#fullwidth2').utilCarousel({ breakPoints : [[600, 1], [800, 2], [1000, 3], [1300, 4],], mouseWheel : false, rewind : true, autoPlay : true, pagination : false }); }); </script> <script> $(document).ready(function() { var movementStrength = 25; var height = movementStrength / $(window).height(); var width = movementStrength / $(window).width(); $("#aboutarea").mousemove(function(e){ var pageX = e.pageX - ($(window).width() / 2); var pageY = e.pageY - ($(window).height() / 2); var newvalueX = width * pageX * -1 - 25; var newvalueY = height * pageY * -1 - 50; $('#aboutarea').css("background-position", newvalueX+"px "+newvalueY+"px"); }); }); </script> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script> <script type="text/javascript" src="dribbble.js"></script> <script type="text/javascript"> $(function () { $('#user').dribbble({ player: 'MCBDesign', total: 1 }); }); </script>

  • Coupling/Cohesion

    - by user559142
    Hi All, Whilst there are many good examples on this forum that contain examples of coupling and cohesion, I am struggling to apply it to my code fully. I can identify parts in my code that may need changing. Would any Java experts be able to take a look at my code and explain to me what aspects are good and bad. I don't mind changing it myself at all. It's just that many people seem to disagree with each other and I'm finding it hard to actually understand what principles to follow... package familytree; /** * * @author David */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here KeyboardInput in = new KeyboardInput(); FamilyTree familyTree = new FamilyTree(in, System.out); familyTree.start(); } } package familytree; import java.io.PrintStream; /** * * @author David */ public class FamilyTree { /** * @param args the command line arguments */ private static final int DISPLAY_FAMILY_MEMBERS = 1; private static final int ADD_FAMILY_MEMBER = 2; private static final int REMOVE_FAMILY_MEMBER = 3; private static final int EDIT_FAMILY_MEMBER = 4; private static final int SAVE_FAMILY_TREE = 5; private static final int LOAD_FAMILY_TREE = 6; private static final int DISPLAY_ANCESTORS = 7; private static final int DISPLAY_DESCENDANTS = 8; private static final int QUIT = 9; private KeyboardInput in; private Family family; private PrintStream out; public FamilyTree(KeyboardInput in, PrintStream out) { this.in = in; this.out = out; family = new Family(); } public void start() { out.println("\nWelcome to the Family Tree Builder"); //enterUserDetails(); initialise(); while (true) { displayFamilyTreeMenu(); out.print("\nEnter Choice: "); int option = in.readInteger(); if (option > 0 && option <= 8) { if (quit(option)) { break; } executeOption(option); } else { out.println("Invalid Choice!"); } } } //good private void displayFamilyTreeMenu() { out.println("\nFamily Tree Menu"); out.println(DISPLAY_FAMILY_MEMBERS + ".

  • LinkedIn with Pecl OAuth: "got a 400, expected HTTP/1.1 20X or a redirect"

    - by CharlesS
    I have Pecl OAuth with PHP5 on a Debian box and I try to authenticate to LinkedIn. When calling; OAuth-getAccessToken('https://api.lin...')\n#1 I get; PHP Fatal error: Uncaught exception 'OAuthException' with message 'Invalid auth/bad request (got a 400, expected HTTP/1.1 20X or a redirect)' I have tried it from scratch and I have tried the PHP API wrappers that are available and (ofcourse, because they use OAuth Pecl ext) have all the same problem. I read somewhere it might be the timestamp on the server, but I synched that up with ntpdate; it does that quite often now, so the offset with the timeservers is almost 0. What else can it be? Thanks

  • Hue, saturation, brightness, contrast effect in hlsl

    - by Vibhore Tanwer
    I am new to pixel shader, and I am trying to write a simple brightness, contrast, hue, saturation effect. I have written a shader for it but I doubt that my shader is not providing me correct result, Brightness, contrast, saturation is working fine, problem is with hue. if I apply hue between -1 to 1, it seems to be working fine, but to make things more sharp, I need to apply hue value between -180 and 180, like we can apply hue in Paint.NET. Here is my code. // Amount to shift the Hue, range 0 to 6 float Hue; float Brightness; float Contrast; float Saturation; float Alpha; sampler Samp : register(S0); // Converts the rgb value to hsv, where H's range is -1 to 5 float3 rgb_to_hsv(float3 RGB) { float r = RGB.x; float g = RGB.y; float b = RGB.z; float minChannel = min(r, min(g, b)); float maxChannel = max(r, max(g, b)); float h = 0; float s = 0; float v = maxChannel; float delta = maxChannel - minChannel; if (delta != 0) { s = delta / v; if (r == v) h = (g - b) / delta; else if (g == v) h = 2 + (b - r) / delta; else if (b == v) h = 4 + (r - g) / delta; } return float3(h, s, v); } float3 hsv_to_rgb(float3 HSV) { float3 RGB = HSV.z; float h = HSV.x; float s = HSV.y; float v = HSV.z; float i = floor(h); float f = h - i; float p = (1.0 - s); float q = (1.0 - s * f); float t = (1.0 - s * (1 - f)); if (i == 0) { RGB = float3(1, t, p); } else if (i == 1) { RGB = float3(q, 1, p); } else if (i == 2) { RGB = float3(p, 1, t); } else if (i == 3) { RGB = float3(p, q, 1); } else if (i == 4) { RGB = float3(t, p, 1); } else /* i == -1 */ { RGB = float3(1, p, q); } RGB *= v; return RGB; } float4 mainPS(float2 uv : TEXCOORD) : COLOR { float4 col = tex2D(Samp, uv); float3 hsv = rgb_to_hsv(col.xyz); hsv.x += Hue; // Put the hue back to the -1 to 5 range //if (hsv.x > 5) { hsv.x -= 6.0; } hsv = hsv_to_rgb(hsv); float4 newColor = float4(hsv,col.w); float4 colorWithBrightnessAndContrast = newColor; colorWithBrightnessAndContrast.rgb /= colorWithBrightnessAndContrast.a; colorWithBrightnessAndContrast.rgb = colorWithBrightnessAndContrast.rgb + Brightness; colorWithBrightnessAndContrast.rgb = ((colorWithBrightnessAndContrast.rgb - 0.5f) * max(Contrast + 1.0, 0)) + 0.5f; colorWithBrightnessAndContrast.rgb *= colorWithBrightnessAndContrast.a; float greyscale = dot(colorWithBrightnessAndContrast.rgb, float3(0.3, 0.59, 0.11)); colorWithBrightnessAndContrast.rgb = lerp(greyscale, colorWithBrightnessAndContrast.rgb, col.a * (Saturation + 1.0)); return colorWithBrightnessAndContrast; } technique TransformTexture { pass p0 { PixelShader = compile ps_2_0 mainPS(); } } Please If anyone can help me learning what am I doing wrong or any suggestions? Any help will be of great value. EDIT: Images of the effect at hue 180: On the left hand side, the effect I got with @teodron answer. On the right hand side, The effect Paint.NET gives and I'm trying to reproduce.

  • Apache returns 304, I want it to ignore anything from client and send the page

    - by Ayman
    I am using Apache HTTPD 2.2 on Windows. mod_expires is commented out. Most other stuff are not changed from the defaults. gzip is on. I made some changes to my .js files. My client gets one 304 response for one of the .js files and never gets the rest. How can I force Apache to sort of flush everything and send all new files to the client? The main html file includes these scripts in the head section of the main page: <script src="js/jquery-1.7.1.min.js" type="text/javascript"> </script> <script src="js/jquery-ui-1.8.17.custom.min.js" type="text/javascript"></script> <script src="js/trex.utils.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.core.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.codes.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.emv.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.b24xtokens.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.iso.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.span2.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.amex.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.abi.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.barclays.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.bnet.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.visa.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.atm.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.apacs.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.pstm.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.stm.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.thales.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.fps-saf.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.fps-iso.js" type="text/javascript" charset="utf-8"></script> <script src="js/trex.app.js" type="text/javascript" charset="utf-8"></script> Apache access log has the following: [07/Jul/2013:16:50:40 +0300] "GET /trex/index.html HTTP/1.1" 200 2033 "-" [07/Jul/2013:16:50:40 +0300] "GET /trex/js/trex.fps-iso.js HTTP/1.1" 304 [08/Jul/2013:07:54:35 +0300] "GET /trex/index.html HTTP/1.1" 304 - "-" [08/Jul/2013:07:54:35 +0300] "GET /trex/js/trex.iso.js HTTP/1.1" 200 12417 [08/Jul/2013:07:54:35 +0300] "GET /trex/js/trex.amex.js HTTP/1.1" 200 6683 [08/Jul/2013:07:54:35 +0300] "GET /trex/js/trex.fps-saf.js HTTP/1.1" 200 2925 [08/Jul/2013:07:54:35 +0300] "GET /trex/js/trex.fps-iso.js HTTP/1.1" 304 Chrome request headers are as below: THis file is ok, latest: Request URL:http://localhost/trex/js/trex.iso.js Request Method:GET Status Code:200 OK (from cache) THis file is ok, latest: Request URL:http://localhost/trex/js/trex.amex.js Request Method:GET Status Code:200 OK (from cache) This one is also ok: Request URL:http://localhost/trex/js/trex.fps-iso.js Request Method:GET Status Code:200 OK (from cache) The rest of the scrips all have 200 OK (from cache).

  • Spritesheet per pixel collision XNA

    - by Jixi
    So basically i'm using this: public bool IntersectPixels(Rectangle rectangleA, Color[] dataA,Rectangle rectangleB, Color[] dataB) { int top = Math.Max(rectangleA.Top, rectangleB.Top); int bottom = Math.Min(rectangleA.Bottom, rectangleB.Bottom); int left = Math.Max(rectangleA.Left, rectangleB.Left); int right = Math.Min(rectangleA.Right, rectangleB.Right); for (int y = top; y < bottom; y++) { for (int x = left; x < right; x++) { Color colorA = dataA[(x - rectangleA.Left) + (y - rectangleA.Top) * rectangleA.Width]; Color colorB = dataB[(x - rectangleB.Left) + (y - rectangleB.Top) * rectangleB.Width]; if (colorA.A != 0 && colorB.A != 0) { return true; } } } return false; } In order to detect collision, but i'm unable to figure out how to use it with animated sprites. This is my animation update method: public void AnimUpdate(GameTime gameTime) { if (!animPaused) { animTimer += (float)gameTime.ElapsedGameTime.TotalMilliseconds; if (animTimer > animInterval) { currentFrame++; animTimer = 0f; } if (currentFrame > endFrame || endFrame <= currentFrame || currentFrame < startFrame) { currentFrame = startFrame; } objRect = new Rectangle(currentFrame * TextureWidth, frameRow * TextureHeight, TextureWidth, TextureHeight); origin = new Vector2(objRect.Width / 2, objRect.Height / 2); } } Which works with multiple rows and columns. and how i call the intersect: public bool IntersectPixels(Obj me, Vector2 pos, Obj o) { Rectangle collisionRect = new Rectangle(me.objRect.X, me.objRect.Y, me.objRect.Width, me.objRect.Height); collisionRect.X += (int)pos.X; collisionRect.Y += (int)pos.Y; if (IntersectPixels(collisionRect, me.TextureData, o.objRect, o.TextureData)) { return true; } return false; } Now my guess is that i have to update the textureData everytime the frame changes, no? If so then i already tried it and miserably failed doing so :P Any hints, advices? If you need to see any more of my code just let me know and i'll update the question. Updated almost functional collisionRect: collisionRect = new Rectangle((int)me.Position.X, (int)me.Position.Y, me.Texture.Width / (int)((me.frameCount - 1) * me.TextureWidth), me.Texture.Height); What it does now is "move" the block up 50%, shouldn't be too hard to figure out. Update: Alright, so here's a functional collision rectangle(besides the height issue) collisionRect = new Rectangle((int)me.Position.X, (int)me.Position.Y, me.TextureWidth / (int)me.frameCount - 1, me.TextureHeight); Now the problem is that using breakpoints i found out that it's still not getting the correct color values of the animated sprite. So it detects properly but the color values are always: R:0 G:0 B:0 A:0 ??? disregard that, it's not true afterall =P For some reason now the collision area height is only 1 pixel..

  • Tuning Default WorkManager - Advantages and Disadvantages

    - by Murali Veligeti
    Before discussing on Tuning Default WorkManager, lets have a brief introduction on What is Default WorkManger Before Weblogic Server 9.0 release, we had the concept of Execute Queues. WebLogic Server (before WLS 9.0), processing was performed in multiple execute queues. Different classes of work were executed in different queues, based on priority and ordering requirements, and to avoid deadlocks. In addition to the default execute queue, weblogic.kernel.default, there were pre-configured queues dedicated to internal administrative traffic, such as weblogic.admin.HTTP and weblogic.admin.RMI.Users could control thread usage by altering the number of threads in the default queue, or configure custom execute queues to ensure that particular applications had access to a fixed number of execute threads, regardless of overall system load. From WLS 9.0 release onwards WebLogic Server uses is a single thread pool (single thread pool which is called Default WorkManager), in which all types of work are executed. WebLogic Server prioritizes work based on rules you define, and run-time metrics, including the actual time it takes to execute a request and the rate at which requests are entering and leaving the pool.The common thread pool changes its size automatically to maximize throughput. The queue monitors throughput over time and based on history, determines whether to adjust the thread count. For example, if historical throughput statistics indicate that a higher thread count increased throughput, WebLogic increases the thread count. Similarly, if statistics indicate that fewer threads did not reduce throughput, WebLogic decreases the thread count. This new strategy makes it easier for administrators to allocate processing resources and manage performance, avoiding the effort and complexity involved in configuring, monitoring, and tuning custom executes queues. The Default WorkManager is used to handle thread management and perform self-tuning.This Work Manager is used by an application when no other Work Managers are specified in the application’s deployment descriptors. In many situations, the default Work Manager may be sufficient for most application requirements. WebLogic Server’s thread-handling algorithms assign each application its own fair share by default. Applications are given equal priority for threads and are prevented from monopolizing them. The default work-manager, as its name tells, is the work-manager defined by default.Thus, all applications deployed on WLS will use it. But sometimes, when your application is already in production, it's obvious you can't take your EAR / WAR, update the deployment descriptor(s) and redeploy it.The default work-manager belongs to a thread-pool, as initial thread-pool comes with only five threads, that's not much. If your application has to face a large number of hits, you may want to start with more than that.Well, that's quite easy. You have  two option to do so.1) Modify the config.xmlJust add the following line(s) in your server definition : <server> <name>AdminServer</name> <self-tuning-thread-pool-size-min>100</self-tuning-thread-pool-size-min> <self-tuning-thread-pool-size-max>200</self-tuning-thread-pool-size-max> [...] </server> 2) Adding some JVM parameters Add the following system property in setDomainEnv.sh/setDomainEnv.cmd or startWebLogic.sh/startWebLogic.cmd : -Dweblogic.threadpool.MinPoolSize=100 -Dweblogic.threadpool.MaxPoolSize=100 Reboot WLS and see the option has been taken into account . Disadvantage: So far its fine. But here there is an disadvantage in tuning Default WorkManager. Internally Weblogic Server has many work managers configured for different types of work.  if we run out of threads in the self-tuning pool(because of system property -Dweblogic.threadpool.MaxPoolSize) due to being undersized, then important work that WLS might need to do could be starved.  So, while limiting the self-tuning would limit the default WorkManager and internally it also limits all other internal WorkManagers which WLS uses.So the best alternative is to override the default WorkManager that means creating a WorkManager for the Application and assign the WorkManager for the application instead of tuning the Default WorkManager.

  • Circle-Line Collision Detection Problem

    - by jazzdawg
    I am currently developing a breakout clone and I have hit a roadblock in getting collision detection between a ball (circle) and a brick (convex polygon) working correctly. I am using a Circle-Line collision detection test where each line represents and edge on the convex polygon brick. For the majority of the time the Circle-Line test works properly and the points of collision are resolved correctly. Collision detection working correctly. However, occasionally my collision detection code returns false due to a negative discriminant when the ball is actually intersecting the brick. Collision detection failing. I am aware of the inefficiency with this method and I am using axis aligned bounding boxes to cut down on the number of bricks tested. My main concern is if there are any mathematical bugs in my code below. /* * from and to are points at the start and end of the convex polygons edge. * This function is called for every edge in the convex polygon until a * collision is detected. */ bool circleLineCollision(Vec2f from, Vec2f to) { Vec2f lFrom, lTo, lLine; Vec2f line, normal; Vec2f intersectPt1, intersectPt2; float a, b, c, disc, sqrt_disc, u, v, nn, vn; bool one = false, two = false; // set line vectors lFrom = from - ball.circle.centre; // localised lTo = to - ball.circle.centre; // localised lLine = lFrom - lTo; // localised line = from - to; // calculate a, b & c values a = lLine.dot(lLine); b = 2 * (lLine.dot(lFrom)); c = (lFrom.dot(lFrom)) - (ball.circle.radius * ball.circle.radius); // discriminant disc = (b * b) - (4 * a * c); if (disc < 0.0f) { // no intersections return false; } else if (disc == 0.0f) { // one intersection u = -b / (2 * a); intersectPt1 = from + (lLine.scale(u)); one = pointOnLine(intersectPt1, from, to); if (!one) return false; return true; } else { // two intersections sqrt_disc = sqrt(disc); u = (-b + sqrt_disc) / (2 * a); v = (-b - sqrt_disc) / (2 * a); intersectPt1 = from + (lLine.scale(u)); intersectPt2 = from + (lLine.scale(v)); one = pointOnLine(intersectPt1, from, to); two = pointOnLine(intersectPt2, from, to); if (!one && !two) return false; return true; } } bool pointOnLine(Vec2f p, Vec2f from, Vec2f to) { if (p.x >= min(from.x, to.x) && p.x <= max(from.x, to.x) && p.y >= min(from.y, to.y) && p.y <= max(from.y, to.y)) return true; return false; }

  • Drawing random smooth lines contained in a square [migrated]

    - by Doug Mercer
    I'm trying to write a matlab function that creates random, smooth trajectories in a square of finite side length. Here is my current attempt at such a procedure: function [] = drawroutes( SideLength, v, t) %DRAWROUTES Summary of this function goes here % Detailed explanation goes here %Some parameters intended to help help keep the particles in the box RandAccel=.01; ConservAccel=0; speedlimit=.1; G=10^(-8); % %Initialize Matrices Ax=zeros(v,10*t); Ay=Ax; vx=Ax; vy=Ax; x=Ax; y=Ax; sx=zeros(v,1); sy=zeros(v,1); % %Define initial position in square x(:,1)=SideLength*.15*ones(v,1)+(SideLength*.7)*rand(v,1); y(:,1)=SideLength*.15*ones(v,1)+(SideLength*.7)*rand(v,1); % for i=2:10*t %Measure minimum particle distance component wise from boundary %for each vehicle BorderGravX=[abs(SideLength*ones(v,1)-x(:,i-1)),abs(x(:,i-1))]'; BorderGravY=[abs(SideLength*ones(v,1)-y(:,i-1)),abs(y(:,i-1))]'; rx=min(BorderGravX)'; ry=min(BorderGravY)'; % %Set the sign of the repulsive force for k=1:v if x(k,i)<.5*SideLength sx(k)=1; else sx(k)=-1; end if y(k,i)<.5*SideLength sy(k)=1; else sy(k)=-1; end end % %Calculate Acceleration w/ random "nudge" and repulive force Ax(:,i)=ConservAccel*Ax(:,i-1)+RandAccel*(rand(v,1)-.5*ones(v,1))+sx*G./rx.^2; Ay(:,i)=ConservAccel*Ay(:,i-1)+RandAccel*(rand(v,1)-.5*ones(v,1))+sy*G./ry.^2; % %Ad hoc method of trying to slow down particles from jumping outside of %feasible region for h=1:v if abs(vx(h,i-1)+Ax(h,i))<speedlimit vx(h,i)=vx(h,i-1)+Ax(h,i); elseif (vx(h,i-1)+Ax(h,i))<-speedlimit vx(h,i)=-speedlimit; else vx(h,i)=speedlimit; end end for h=1:v if abs(vy(h,i-1)+Ay(h,i))<speedlimit vy(h,i)=vy(h,i-1)+Ay(h,i); elseif (vy(h,i-1)+Ay(h,i))<-speedlimit vy(h,i)=-speedlimit; else vy(h,i)=speedlimit; end end % %Update position x(:,i)=x(:,i-1)+(vx(:,i-1)+vx(:,i))/2; y(:,i)=y(:,i-1)+(vy(:,i-1)+vy(:,1))/2; % end %Plot position clf; hold on; axis([-100,SideLength+100,-100,SideLength+100]); cc=hsv(v); for j=1:v plot(x(j,1),y(j,1),'ko') plot(x(j,:),y(j,:),'color',cc(j,:)) end hold off; % end My original plan was to place particles within a square, and move them around by allowing their acceleration in the x and y direction to be governed by a uniformly distributed random variable. To keep the particles within the square, I tried to create a repulsive force that would push the particles away from the boundaries of the square. In practice, the particles tend to leave the desired "feasible" region after a relatively small number of time steps (say, 1000)." I'd love to hear your suggestions on either modifying my existing code or considering the problem from another perspective. When reading the code, please don't feel the need to get hung up on any of the ad hoc parameters at the very beginning of the script. They seem to help, but I don't believe any beside the "G" constant should truly be necessary to make this system work. Here is an example of the current output: Many of the vehicles have found their way outside of the desired square region, [0,400] X [0,400].

  • 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? Error: not well-formed Source File: file:///Users/Greg/Documents/myscript.user.js Line: 1, Column: 1 Source Code: // ==UserScript==
