• Setting the colour scheme for a Silverlight app from an external resource

  - by Alex Angas

  I have a Silverlight 3 application containing six custom user controls. I'd like to load the colour scheme for these controls from an external resource. The code and XAML containing a default colour scheme would be built in the XAP. Then a parameter on the object tag would contain a URL from where alternate colours can be dynamically loaded. By the way, the Silverlight 3 application theme feature could be used if that's possible but is really overkill. Only colours need to be changed. Is this possible and how would you recommend to do it?

• MooTools Classes and JsDoc

  - by Joel Alejandro

  I have the following Moo class: Nem.Ui.Window = new Class({ Implements: [Options, Events], options: { caption: "Ventana", icon: $empty, centered: true, id: $empty, width: $empty, height: $empty, modal: false, desktop: $empty, x: $empty, y: $empty, layout: $empty }, initialize: function(options) { this.setOptions(options); /* ... */ }, setHtmlContents: function(content) { /* ... */ }, setText: function(text) { /* ... */ }, close: function(win) { /* ... */ }, /* ... */ }); I want to document it with JsDoc. I read you can use @lends [class].prototype inside new Class and mark initialize with the @constructs tag. How can I mark methods and events such? I.E.: setHtmlContents should be a method, close should be an event. Also, can the elements under options be documented, somehow?

• Jquery, "$.each(", function returns error in IE. 'Length' is null or not an object

  - by Collin Estes

  My code is working fine in FireFox but my users are restricted to IE. I'm getting an error though in IE, related to my JQUERY function. populateTable:function(returnList) { var self = this; var eat = $.evalJSON(returnList.firstChild.textContent) $.each(eat,function() { $("<tr><td>" + this.reportId + "</td><td>" + this.description + "</td><td>" + this.drawingNumber + "<td></tr>").insertAfter(self.tblResults[0].childNodes[1]); }) } IE is erring on the $.each with the message below: 'Length' is null or not an object Any ideas or maybe a workaround for the $.each function? Update: returnList is an XML document object from an Ajax call. I'm trying to retrieve the JSON object string located within the XML tag.

• jQuery Highlight Radio Labels Only

  - by Michael

  I'm trying to use jQuery validation to highlight the labels for my radio buttons only, and not the labels for my other inputs. I have a label for my radio button set called 'type'. I can't seem to get it to work! $(document).ready(function(){ $("#healthForm").validate({ highlight: function(element, errorClass) { $(element).addClass(errorClass) $(element.form).find("label[for='type']") .addClass("radioerror"); }, unhighlight: function(element, errorClass) { $(element).removeClass(errorClass) $(element.form).find("label[for='type']") .removeClass("radioerror"); }, errorPlacement: function(error, element) { } }); });

• Is there a way to list all the database queries my wordpress install is making for a given event?

  - by mattloak

  Using a method similar to the one described here: (http://stackoverflow.com/questions/14873/how-do-i-display-database-query-statistics-on-wordpress-site), I can see the total number of queries being made when I load a page. Now I'd like to output a list of the queries that are being made when the page loads. This would allow me to see who my biggest resource hogs are without having to go through the process of elimination of all my plugins and theme scripts. How would I do this? Thanks.

• Problem With HTML5 Application Cache Whitelist - Won't Ignore Items

  - by Ryan Donnelly

  I'm trying to use HTML5 Application Cache to speed some things up on an iPhone webapp. It works great for storing images, css and JS, but the problem is that it also tries to store the HTML. I haven't been able to get it to ignore the html and stop storing it in the cache. From what I've read, I have to "whitelist" the files and directories that I want to load no matter what. I've tried listing the files I want cached explicitly, and I've tried adding a series of things under the "NETWORK:" heading. I've tried * / /* http://mysite.com http://mysite.com/ http://mysite.com/* None of them seem to work. Is there any way to ignore HTML files by MIME-Type or anything? Any advice would be appreciated. Ryan P.S. Of course, my site is not mysite.com..I just used that for simplicity.

  I am trying to load a fixture for my tests which has a password column (binary datatype). The tool i am using uses EzCrypto gem for encrypting and decrypting passwords before they are stored/retrieved. Now if my column is binary i thought rails would automatically store the password as encrypted - but all i get is: 1) Error: test_is_working(FirstTest): RuntimeError: Failed to decode the field. Incorrect key? /Library/Ruby/Gems/1.8/gems/mislav-will_paginate-2.3.11/lib/will_paginate/finder.rb:170:in method_missing' unit/first_test.rb:8:insetup' 2) Error: test_sanity(FirstTest): RuntimeError: Failed to decode the field. Incorrect key? unit/first_test.rb:8:in `setup' Fixture file looks like this: first_hussle: type: FirstAccount user: jsewq username: [email protected] password: 'abc123' any clues?

• What is the correct usage of blueprint-typography-body([$font-size])?

  - by Alexis Abril

  Recent convert to RoR and I've been using Compass w/ Blueprint to dip into the proverbial pool. Compass has been fantastic, but I've come across something strange within the Typography library. The blueprint-typography-body mixin contains the following: =blueprint-typography-body($font-size: $blueprint-font-size) line-height: 1.5 +normal-text font-size: 100% * $font-size / 16px My question revolves around "font-size." I'm a bit lost, as I would expect to pass in a font size and have that size reflected upon page load. However, in this scenario the formula seems to dictate a percentage against the default font. ie: +blueprint-typography-body(10px) //produces 7.5px off of the default font size of 12px from what I can tell. In essence, I'm curious if there is a standard to setting font size within Compass other than explicitly declaring "font-size: 10px". Note: The reason I'm leaning towards Blueprint/Compass font stylings is due to the standardization of line-heights, fonts and colors.

• Django, javascript and code reuse problem

  - by dragoon

  Hi, I have some sort of a design problem with my Django AJAX application. I have a template where I initialize js variable from django context variable like so: var test = "{{ test }}"; This variable is than used in a number of js functions that are needed for interface to work properly. So now I'm trying to reuse some content from this page in another page that loads it dynamically on some user interaction using jQuery.load(..), and I don't see any way how I can initialize that variable, so js functions don't work now. Is there any solution for this or may be I'm doing it wrong? Thanks.

• spamassassin setup how to make sure X-Spam-Status is allways written.

  - by DoviG

  Hi, I just found out that spamassassin skips checking for email bigger than 250KB by default. Due to a coding bug, I check for the X-Spam-Status header in incoming emails and did not take into account the fact that it might be null. I know that I can increase the size of the limit by configuration but it may cause a load issue on my server. Since I do not want to redeploy my application at this time I was wondering if there is a way to make sure this header exists automatically in every email, either by spamassassin configuration or by postfix or something else. Thanks, Dov.

  - by ramdaz

  Hi I am trying to integrate Django-Paypal onto a site, where once the customer makes a payment I need to send a dynamic URL from which the user can download some specific information.

• JQuery UI Dialog query dialog DOM

  - by Travis

  The following simply loads a jquery-ui dialog from an external html file. $('#showdialog').click(function(e) { var div = $('<div>loading...</div>'); div.dialog({ modal: true, open: function() { div.load('anotherpage.html'); } }); e.preventDefault(); }); After the DOM loads from the external html file, I'd like to interrogate it with JQuery. For example, supposing anothorpage.html had a bunch of anchors on it, I'd like to wire up click handlers for them when it loads into the dialog. Any ideas?

• Pipe less to emacs

  - by Steve

  When viewing piped output to Less, sometimes I'd like to be able to view it in Emacs in order to get syntax highlighting and use emacs commands for searching, marking, copying, etc. I see that Less has a v command that can be used to open the currently viewed file in $EDITOR. Unfortunately this doesn't work when viewing piped input. Also, I don't know how to get Emacs to display stdin as a read-only document. So, is it possible to set up Less with something like v but that pumps the current buffer into Emacs as a read-only file? Thanks.

• Setting JMX attribute on VM as command line paramater

  - by 117440226733149663383

  I've done some searching, but can't seem to find a way to do this. We'd like to proactively monitor our permgen space via JMX. It seems the best way to do this is through the UsageThreshold attribute on the "PS Perm Gen" MemoryPool. By default, this is set to 0. Is there a way to specify this, or any JMX attribute, as a -D parameter to VM so this can be set automatically at startup? Or is there another mechanism to load JMX attributes automatically? Thanks.

• Lazy loading in Hibernate

  - by Steve

  My Java Web application uses Hibernate to perform ORM. In some of my objects, I use lazy loading to avoid getting data until I absolutely need it. The problem is that I load the initial object in a session, and then that session is destroyed. When I later attempt to resolve the lazy-loaded collections in my object I get the following error: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: common.model.impl.User.groups, no session or session was closed I tried associating a new session with the collection and then resolving, but this gives the same results. Does anyone know how I can resolve the lazy collections once the original session is gone? Thanks... --Steve

• Most effective way of drawing 4 lines in an iPhone app?

  - by Ross

  basic question, but I'm unsure. Not looking for code as an answer. I want to draw 4 short lines 1px lines on a view. What is the best way to approach this task? Options:- Load an image of the line, then create 4 UIImageViews with it. Create my own subclass of a UIView that draws a line in the draw rect method. Draw elsewhere on another view, another UIImageView that has an UIImage inside it (is this possible?) Another way? Thanks Ross

• binary search and trio

  - by user121196

  given a large list of alphabetically sorted words in a file,I need to write a program that, given a word x, determines if x is in the list. priorties: 1. speed. 2. memory I already know I can use (n is number of words, m is average length of the words) 1. a tri, time is O(log(n)), space(best case) is O(log(n*m)), space(worst case) is O(n*m). 2. load the complete list into memory, then binary search, time is O(log(n)), space is O(n*m) I'm not sure about the complexity on tri, please correct me if they are wrong. Also are there other good approaches?

• VS development on FDCC compliant Workstation

  - by paramesh kudlur

  Hi, I have a FDCC compliant workstation with FIPS 140-1 (Level 1) enabled. Now, i cannot run/debug any VS 2005/2008 applications on my machine I get the following error message on my browser Parser Error Message: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms. the Error points to line no 1 of default.aspx.cs file using system; The only way to successfully debug/run my application is to set the following registry key to 0 HKLM\System\CurrentControlSet\Control\Lsa\fipsalgorithmpolicy I understand that there are some Cryptographic algorithms that are not FIPS compliant on XP SP2 but i am not using cryptography at all. For that matter, the solution contains just default.aspx page with default code in .cs file, and even that fails to run. So my question is why the webpage fails to load, and why the error points to line #1 "using System;" statement? My next question is how can i develop on FIPS compliant locked down maching where i do not have edit rights on registry Thanks kudlur

• Sub-process /usr/bin/dpkg returned an error code (1)

  - by Delirium tremens

  I'm trying to find a parental control for Ubuntu that turns adult site words into *. I have tried webcontentcontrol (doesn't even ask me to set a password), mobicip (doesn't even get listed in package names). My family can see my adult bookmark names and that's really embarrassing. I tried sudo apt-get remove webcontentcontrol sudo apt-get -f install sudo apt-get upgrade sudo pkill webcontentcontrol sudo apt-get remove webcontentcontrol but still can't uninstall it. Googling for that error message resulted in a solution that is first said dangerous, later said wrong. After sudo apt-get remove webcontentcontrol, I always get the error message "Sub-process /usr/bin/dpkg returned an error code (1)". What should I do? The full error message is in brazilian portuguese. Should I post it anyway? I have just installed nanny, but while webcontentcontrol is installed, it doesn't load.
