• Wordpress FORCE UPDATE of permalink settings

  - by Scott B

  I've been having issues on creating new wordpress blogs where I'm setting permalinks via script on theme activation. However, even though they appear to be correct when I check the permalink settings in WP, my new pages are throwing 404 errors. The only fix I've found is that I have to go back to permalink options and click "Save Changes", even though, according to the display, I've made no changes to need to save... I'm setting permalinks to /%postname%/ Here's how I'm doing it. if(get_option('permalink_structure')==""){update_option('permalink_structure', '/%postname%/');} That script gets run when my theme is activated. Any ideas why it only partially does the job?

• Explanation for expires header

  - by sushil bharwani

  I have a joomla application working on Apache.To improve site performace we have written a .htaccess file to root of the application with setting a far future expires header to all the static content. As desired first time the files load in fresh with 200 status code. when again click on the same link many of the files are served directly from cache. I need explanation for two things When i press f5 then a number of files load with 304 status code however i expected them to be coming directly from cache without hitting the server for a status header? When i close the browser and come back to the same page again i see the same thing happening a number of files load with 304 status code although i thought they will load directly from the browser cache? I understand that 304 also servs file from browser cache but i want to avoid the header communication between servers as my static files wont ever change. Also i want to add that my requests are over a https connection does that create any issue.

• Toggle a CSS selector using JQuery

  - by BEECHBOY707

  I am trying to toggle the display of a CSS selector (ie.to show/hide it) using JQuery. I successfully toggled the display of a div, but want to do this now with the CSS selector :after. The CSS selector is being used to create the arrow on the box. My attempt can be seen here: http://jsfiddle.net/beechboy707/7um9knxt/1/ Here is an extract from it showing the Jquery which is supposed to relate to the CSS selector: $("#supportus-button-1").click(function () { $(".supportus-button:after").toggle(); }); Many thanks for your help, Max

• Creating an image from webcam every x miliseconds

  - by Rita

  Hello everyone, I am using c# to integrate with a web cam. I need to generate a snapshot image every x miliseconds and save it to file. I already have the code up and running to save to file on a button click event, however I wonder what am I supposed to do when taking snapshots in the background - Should this be multi threaded? I'm honestly not sure. I could just block the UI thread, put Thread.Sleep and then just take the snapshot, but I don't know if this is right. I thought of using a background worker, but I am now experiencing cross threaded difficulties with SendMessage... So I wonder if I should even go and bother to multi-thread or just block the UI. Help greatly appertained, thanks in advance.

• Keyboard focus being stolen by Flash

  - by NewUser

  Performing a search, I noticed several questions dedicated to how to steal/trap the keyboard focus of the visitor. Considering this site is dedicated to programming that's not suprising. I was wondering if anyone can advise me on how to prevent this type of behavior. Losing keyboard focus to flash basically removes my browser's functionality until I use the mouse to click elsewhere (I use Mozilla Firefox). Anyone know of some kind of plugin or greasemonkey script that will prevent my keyboard focus from being stolen? Normal browser "shortcuts" are rendered useless by having to use the mouse to return keyboard focus to the browser. Edit: Reply to the post below, I do have flashblock / noscript and some other things. My issue is flash that I want to see/interact with stealing my focus. Basically looking for something I can toggle that will prevent flash from getting keyboard focus or a way to force my firefox keyboard commands to the browser

• Subversion and project management web based super tool. Like Team Foundation Server but not TFS.

  - by Rob Stevenson-Leggett

  Hi, We're currently looking at an IT upgrade and I'm after recommendations for a tool which can do some or all of the following. SVN management (authz, web viewer, commit log, diff) Create template projects (1 click e.g. create me a microsite with this name in svn and give these people access) Reporting on code churn, time spent on tasks on a per project basis User story management Basically like Team Foundation Server but that integrates with SVN properly (reason for this - we have a wide range of skill sets and not everyone can use a TFS client). Is there a combination of Trac plugins + something that can create trac instances (a la Dreamhost's admin panel) that can acheive this. On a side note, does anyone have any experience of version controlling designery type files - e.g. PSDs, Illustrator files. Any advice at all appreciated. Cheers, Rob

• Security precautions and techniques for a User-submitted Code Demo Area

  - by Jack W-H

  Hey folks Maybe this isn't really feasible. But basically, I've been developing a snippet-sharing website and I would like it to have a 'live demo area'. For example, you're browsing some snippets and click the Demo button. A new window pops up which executes the web code. I understand there are a gazillion security risks involved in doing this - XSS, tags, nasty malware/drive by downloads, pr0n, etc. etc. etc. The community would be able to flag submissions that are blatantly naughty but obviously some would go undetected (and, in many cases, someone would have to fall victim to discover whatever nasty thing was submitted). So I need to know: What should I do - security wise - to make sure that users can submit code, but that nothing malicious can be run - or executed offsite, etc? For your information my site is powered by PHP using CodeIgniter. Jack

• Multiple shapes on Android

  - by LucaB

  Hi Hi I'm trying to build a layout where some shapes will popup every 2 seconds. If the user will click one of these shapes, they have to disappear. What is the correct way of doing this? I thought about a thread, but i missed out. Here's my code at the moment (is not working): public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); l = new LinearLayout(this); setContentView(l); int counter = 1; View v = new CustomDrawableView(this,20,50); l.addView(v); Thread t = new Thread() { public void run() { while (true) { Log.i("THREAD","INSIDE"); View h = new CustomDrawableView(c, (int)Math.round(Math.random()*100), (int)Math.round(Math.random()*100)); SystemClock.sleep(2000); l.addView(h); } } }; t.start(); }

• Help with pointers in Cocoa

  - by G.P. Burdell

  I'm trying to make a simple calculator application in cocoa. The program hangs when I click on one of my buttons. I think I've traced the problem to the part of my controller that adds a digit to the end of the number currently on the display: - (void)updateNumber:(int)buttonClicked{ *self.activeNumberPointer = *self.activeNumberPointer * 10 + buttonClicked; [outputField setFloatValue:*self.activeNumberPointer]; } I used a pointer to the "activeNumber" in order to allow my program to tell which of the two operands I'm editing. Any help appreciated, thanks.

• form not showing

  - by Luke

  Perhaps this has something to do with it being the mainForm, but I'll ask the question. I have my mainForm that is the first to load when the program is booted. I then click a button called Add, which should open a new form, and close the mainForm. The problem is, is shows the new form for a split second, then closes both. The code: private void addFrmBtn_Click(object sender, EventArgs e) { saveForm saveform = new saveForm(); saveform.Show(); this.Close(); }

• Visual Studio 2010 failed tests throw exceptions

  - by Dave Hanson

  In VisualStudio2010 Ultimate RC I cannot figure out how to suppress {"CollectionAssert.AreEqual failed. (Element at index 0 do not match.)"} from Microsoft.VisualStudio.TestTools.UnitTesting.AssertFailedException If i Ctrl+Alt+E I get the exception dialog; however that exception doesn't seem to be in there to be suppressed. Does anyone else have any experience with this? I don't remember having to suppress these Assert fails in studio 2008 when running unit tests. My tests would fail and I could just click on the TestResults to see which tests failed instead of fighting through these dialogs. For now I guess I'll just run my tests through the command window.

• Ajax And REST: Can I send an ajax request to a REST service and recieve response?

  - by Morteza M.

  Hi everybody here, I want to use mootools and SqueezBox class to handle a request to a RESTful service. I don't want to use any server-side script. I am using AJAX. I send a request to the following url using GET method. http://www.idevcenter.com/api/v1/links/links-upcoming.json but I receive a 404 error. Is it because cross-site scripting? here is my code: SqueezeBox.initialize({handler:'url',ajaxOptions:{method:'GET'}}); $('a.modal').addEvent('click',function(e){ new Event(e).stop(); SqueezeBox.fromElement($('a.modal')); }); In Firebug console, sometimes 'aborted' is shown and sometimes '404'.what is wrong with that?

• CodeIgniter based e-shop, shipping and gift address design problem

  - by alexander

  While building an ecommerce platform I have run into design problems. I'm working with the built-in CodeIgniter's cart class. It stores all the cart information in session. Let say that cart has already been filled with products and user clicks checkout. When should I store order in database? Just after that click or after several steps of gathering information and stoing it in session? How to deal with additional features like different shipping methods? Should I add it to the basket first and get additional (gift address) to session? I dont want to store it in database because of the relation between gift address and order is needed and since I dont know what's the ID of the order. I'm puzzled :) Additionally I think its crucial to keep cart aware of shipping methods and additional bought services (by selecting gift address there is an extra fee) because the cart content is just like an reciept? In brief, what is the best practice to process checkout?

• Good articles to read on SSL and HTTPS?

  - by Igor Romanov

  I had a problem with accepting invalid SSL certificate in my iPhone program. That problem is solved now, however I came to understanding that I have very abstract idea on how exactly the whole thing is working: how web browser is verifying that received certificate is really for host it communicates to and not faked by same party in the middle? if browser talks to some 3rd party (CA?) to do certificate check? and many other questions... Would someone please recommend good source of information with in-depth enough description of how all parts click together?

• Android - When to use Service

  - by Chris

  This question is related to my previous question: http://stackoverflow.com/questions/2786720/android-service-ping-url So I have an Android app that on the click of a button, opens up a web page. Now, in the background I want to call another http url for gathering stats. My question is does this have to be a service? I know a service is for background tasks that run for an indefinite period of time, while the user is busy doing something else. In my case, all I really need is to get the URL in the background, not show it to the user, instead show the web page to the user. Can I just not write code to get contents of the http url and fire up the activity that displays the web page? Coz all I want is to get the url in the background and be done with it. Or does this have to be done using the Service class? I am confused. Thanks Chris

• How do I add a static library target that compiles before an application compiles in Xcode?

  - by Koning Baard XIV

  I'm creating a static library in C++. The static library itself links to nothing. To test the static library, I'm creating a test program in C++ (you know, with a main function). Now, I want that whenever I click Build in Xcode, it compiles the static library first, then compiles the test program and link that test program to the static library, like this: # The steps indicate the order Xcode should compile it # (Step 1) Static Library <----------. | (Step 2) Test Program -------> Standard Library Also, the test program should use the header files of the static library. Can anyone explain me how to configure this in Xcode? Thanks

• How to write software for my touchpad?

  - by Nona Urbiz

  I have some ideas for improvements on my touchpad, ranging from the run of the mill scroll horizontally at the bottom, tapzones for right click, to more complicated ones. But I have no idea where to get started? I'm working on Windows 7 Home Premium, its an Asus laptop, and I have none of these options natively available to me. Regardless, I want to write something that anyone can use. Where would I start? (it'd be nice to write in c++? is that possible? what are the requirements here? what language would be recommended?)

• I have a filter for jquery masonry - but I want to filter moomasonry

  - by Jason

  Hi, I'm using jquery masonry for layout. But I am considering moving to mootools. I have found a masonry port to mootools, called moomasonry - http://www.crionics.com/products/opensource/mooMasonry/Demos/basic.html With help here, I have a filter on the masonry divs by class: $('a.filter').click(function(){ filterBoxes(this.id); }) function filterBoxes(klass){ if (klass == "all") { klass = "box" } $('#holder').find('.' + klass) .hide() .appendTo('#main') .fadeIn('200') $('#main').find('.box:not(.' + klass + ')') .fadeOut( '200', function(){ $(this).appendTo('#holder') ; }); setTimeout(function(){ $('#main').masonry() },500); } But, how would I filter divs by class in mootools? and have it reload masonry after each filter. See my site for example: http://jasondaydesign.com/masonry_demo/

• Access: Reading deleted record buffer

  - by Michael Itzoe

  According to the Access (2003) documentation, when you delete a record, it's placed in a buffer, then the BeforeDeleteConfirm event is raised, then the AfterConfirmDelete ad Delete events. In my table if a record is deleted, I need to add one of its field values (a quantity value) to a field in another table. I tried setting the quantity to a private variable in the Current event, but as soon as I delete click delete, it looks like the Current event fires again and resets my variable. How can I access the value of a field in a deleted record?

• Dynamic Selectors with Jquery with php while loop

  - by Anders Kitson

  I have a while loop which creates a list of anchor tags each with a unique class name counting from 1 to however many items there are. I would like to change a css attriubute on a specific anchor tag and class when it is clicked so lets say the background color is changed. Here is my code while($row = mysql_fetch_array($results)){ $title = $row['title']; $i++; echo "<a class='$i'>$title</a> } I would like my jquery to look something like this, it is obviously going to be more complicated than this I am just confused as where to start. $(document).ready(function() { $('a .1 .2 .3 .4 and so on').click(function() { $('a ./*whichever class was clicked*/').css('background':'red'); }); });
