• wrong font in a RichTextBox importing from .rtf

  - by giacomellow

  Hi all, I'm developing a microsoft surface application using expression blend+vs 2008. I have a RichTextBox that loads formatted text from an .rtf file. The text is formatted with uppecases, color, and specific font (helvetica-neue). When i load the text, it is displayed in the control with matching format (color and uppecase) but NOT matching font. it seems to use the standard Blend font (Thaoma). the text is loaded with this function: public static RichTextBox SetRTFText(string text, RichTextBox richTextBox) { MemoryStream stream = new MemoryStream(ASCIIEncoding.Default.GetBytes(text)); TextRange documentTextRange = new TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd); documentTextRange.Load(stream, DataFormats.Rtf ); return richTextBox; } thank you all!

• Website image caching with Apache

  - by Piskvor

  How can I get static content on Apache to be {cached by browser} and not {checked for freshness {with every request}}? I'm working on a website hosted on Apache webserver. Recently, I was testing something with headers (Content-Type for different types of content) and saw a lot of conditional requests for images. Example: 200 /index.php?page=1234&action=list 304 /favicon.ico 304 /img/logo.png 304 /img/arrow.png (etc.) Although the image files are static content and are cached by the browser, every time an user opens a page that links to them, they are conditionally requested, to which they send "304 Not Modified". That's good (less data transferred), but it means 20+ more requests with every page load (longer page load due to all those round-trips, even with Keep-Alive and pipelining enabled). How do I tell the browser to keep the existing file and not check for newer version? EDIT: the mod_expires method works, even with the favicon.

• Cannot move ckeditor 4 selection to beginning

  - by Gary Hillerson

  I've been exploring numerous solutions in stackoverflow and elsewhere to try to get ckeditor 4 to scroll to the top after I've programmatically added a number of pages to it, using CKEditor's InsertHtml function. After adding my html, which looks fine, I want to position the cursor at the beginning. Here's one of a variety of things I've tried without success: function MoveCaretToStart(myEditor) { var range = new CKEDITOR.dom.range( editor.document ); range.selectNodeContents(editor.document.getBody()); range.moveToElementEditStart(range.root); // also tried range.collapse(true); range.select(); } ... MoveCaretToStart(CKEDITOR.instances['myEditor']); // which already has contents in it This doesn't throw any errors, but also doesn't move the cursor position (it remains at the end of the doc). I thought this one would be easy, but it sure hasn't been. Any help appreciated.

• Javascript eval limits

  - by user117701

  Is there a limit to javascript's eval, like in lenght? I'm trying to build an app where you can store JS code in the DB, which you can later load and eval in order to execute it, but i'm reaching a limit. First of all, the code has to all be in one line. Any multiline statements are not executed. Next, i'm reaching a limit in length (i guess). If i execute the code manually, it works, but put that same code in the db, load it via ajax, and try to execute it, and it fails. Any ideas why?

• Automatic open Colorbox modal window

  - by user1631168

  I'm using the Colorbox module in Drupal 7. I'm opening an external website. I can make it work with a link. Click here, then click the "colorbox popup" link at the bottom, middle column. The client would like this to open automatically when the page opens. I've created a block and added the following code (from the colorbox site). <script type="text/javascript"> // Display a welcome message on first visit, and set a cookie that expires in 30 days: if (document.cookie.indexOf('visited=true') === -1) { var expires = new Date(); expires.setDate(expires.getDate()+30); document.cookie = "visited=true; expires="+expires.toUTCString(); jQuery.colorbox({html:"http://join.raretearepublic.com/popup/", width:887, height:638}); } </script> But it does not work. Any help would be greatly appreciated.

• Annoying Bug in banner cycle

  - by Davemof

  I have created a rotating banner script for a new site I'm developing View banner here(it rotates every 10 seconds) Unfortunately to the transition seems to be a biut buggy, and the image will fade out, show the same image again and then fade in the new one. I think I have made a simple error somewhere, but can't figure out where it is. the code used to cycle the banners is: In document ready: if ($('.home').length > 0){ $('<img width="100%" />').attr('src', '/assets/img/backgrounds/home/hero'+homecount+'.jpg').load(function(){ $('.hero').append( $(this) ); $('.hero img').fadeIn('medium').delay(10000).fadeOut('slow', loopImages); setHeroHeight(); }); } Outside document ready: function loopImages(){ homecount = homecount+1; if (homecount > 5){ homecount = 1; } $('.hero img') .attr('src', '/assets/img/backgrounds/home/hero'+homecount+'.jpg') .load(function(){ $('.hero img').fadeIn('fast')}).delay(10000).fadeOut('slow', loopImages); } Any help would be greatly appreciated Thanks Dave

• PHP - WideImage class cropping

  - by Kolind

  I am trying to crop a large image to make thumbnails. But I can't get WideImage to save the file. I've tried the following: 1st method: $img = WideImage::load('../files/' . $file_name)->crop('center', 'center', 200, 200); $img->saveToFile('../files/thumb/thumb_' . $file_name); 2nd method: $img = WideImage::load('../files/' . $file_name)->crop('center', 'center', 200, 200); $img->copy('../files/thumb/thumb_' . $file_name); But nothing seems to happen, when I am performing any of these methods. I am getting no errors and no thumbnails. Am I doing something wrong here?

• Implementing a runtime Look Up Table in C#

  - by Yarok

  Hey all, I'm currently working on a robot interface GUI, using C#. The robot has two sensors, and two powered wheels. I need to let the user the option to load a Look Up Table (LUT) during runtime, one for each sensor, that will tell the robot what to do according to the sensor's reading. I think the best way to do it is using a .csv file, formatted like so: index , right wheel order, left wheel order the index is an int between 0-1023 and is actually the sensor's reading. the orders for the right and left wheel are integers, between -500 - 500. Example - left sensor's readings: 1,10,20 meaning: sensor reads 1 -- left wheel 10 rpm right wheel 20 rpm So my question is this: what is the best way to implement it? using a dataset?(if so, how?) using an array? (if so, how do I load it during runtime?) Any help would be much appreciated, Yarok

• PHP/codeigniter - use of exit()

  - by Patrick

  I have a few pages that require login, so all controllers that link to these pages start with $this->checkSession(); //...rest of the code CheckSession should verify the session is still live, otherwise display a message and stop the execution of the rest of the code in the controller: function checkSession() { if (!$this->session->userdata('is_logged_in')) { //the session has expired! $data['main'] = 'confirmation_message'; $data['title'] = "Session expired"; $this->load->vars($data); $this->load->view('template'); exit(); } } . I was expecting these instructions to happen in sequence, but I only get a blank page. How can I make sure exit() gets executed only after all views are loaded?

• Change the value of a dropdown if it is equal to something

  - by Jake Neal

  Sorry if this question has already been asked and answered, but I couldn't find anything specifically for my needs. I have a form that has placeholders and javascript to make sure the form isn't submitted with the placeholders still there. There is a dropdown box that has the value of 'Best time to call'. What I want to do is if this value is passed as the default, I want it to change to something like "n/a" or a blank value. I have achieved this with the comments box using the following javascript, but it doesn't seem to work the same for the dropdown: var comments=document.getElementById('comments').value; if (comments=="Comments") { document.getElementById('comments').value=""; } This isn't a required field so I can't have an alert come up, so I just need to value to be changed if submitted as 'Best time to call'. Hope I have explained everything correctly

• CouchDB read authorization

  - by mdikici

  In couchdb website - technical overview - security and validation - http://couchdb.apache.org/docs/overview.html - it writes that (on reader access part) "To protect document contents, CouchDB documents can have a reader list. This is an optional list of reader-names allowed to read the document. When a reader list is used, protected documents are only viewable by listed users." I searched about how to use it but i found nothing. So is it actually used and if it is how? Thanks. -- Mustafa

  - by Warrior

  I am new to iPhone development. I am converting the date to the desired format and set it to the delegate and get its value in the another view.

• How call soap service using jQuery

  - by Alen D

  I have a problem with calling soap service from php page. I was implemented two page,first page was created in php, and second page was created in asp.net. In asp.net application I have SOAP service, which methods should be called from php. Method on my SOAP service, look like this: [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public bool UpdateVotes(string vote) { //Code } On PHP application I call UpdateVotes method on the next way: $.ajax({ type: "POST", url: "http://localhost:5690/VoteServices.asmx/UpdateVotes", data: "{'vote': '" + vote + "'}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { }, error: function (xhr, status, error) { } }); First I run asp.net application with SOAP service, and than I start php aplication.

• How to clear a cookie programatically?

  - by peter

  Hi All, I am using silverlight unit tests to test an important part of our site. Is it possible to clear cookies before each unit test runs? The problem is that if I do this, HtmlPage.Document.Cookies = ""; It doesn't work. If the cookie already was this, key = value I can do this, HtmlPage.Document.Cookies = "key="; It kind of clears it out, but the string "key" is still part of the cookie. Any ideas? Are there any other classes in .NET that deal with cookies? The functionality seems quite limited when I am dealing with more complicated scenarios.

• What's the best way to set cursor/caret position?

  - by Daniel Bachhuber

  If I'm inserting content into a textarea that TinyMCE has co-opted, what's the best way to set the position of the cursor/caret? I'm using tinyMCE.execCommand("mceInsertRawHTML", false, content); to insert the content, and I'd like set the cursor position to the end of the content. Both document.selection and myField.selectionStart won't work for this, and I feel as though this is going to be supported by TinyMCE (through something I can't find on their forum) or it's going to be a really ugly hack. Later: It gets better; I just figured out that, when you load TinyMCE in WordPress, it loads the entire editor in an embedded iframe. Later (2): I can use document.getElementById('content_ifr').contentDocument.getSelection(); to get the selection as a string, but not a Selection Object that I can use getRangeAt(0) on. Making progress little by little.

• jquery in ajax loaded content

  - by Kim Gysen

  My application is supposed to be a single page application and I have the following code that works fine: home.php: <div id="container"> </div> accordion.php: //Click functions: load content $('#parents').click(function(){ //Load parent in container $('#container').load('http://www.blabla.com/entities/parents/parents.php'); }); parents.php: <div class="entity_wrapper"> Some divs and selectors </div> <script type="text/javascript"> $(document).ready(function(){ //Some jQuery / javascript }); </script> So the content loads fine, while the scripts dynamically loaded execute fine as well. I apply this system repetitively and it continues to work smoothly. I've seen that there are a lot of frameworks available on SPA's (such as backbone.js) but I don't understand why I need them if this works fine. From the backbone.js website: When working on a web application that involves a lot of JavaScript, one of the first things you learn is to stop tying your data to the DOM. It's all too easy to create JavaScript applications that end up as tangled piles of jQuery selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your JavaScript logic, and the database on your server. For rich client-side applications, a more structured approach is often helpful. Well, I totally don't have the feeling that I'm going through the stuff they mention. Adding the javascript per page works really well for me. They are html containers with clear scope and the javascript is just related to that part. More over, the front end doesn't do that much, most of the logic is managed based on Ajax calls to external PHP scripts. Sometimes the js can be a bit more extended for some functionalities, but all just loads as smooth in less than a second. If you think that this is bad coding, please tell me why I cannot do this and more importantly, what is the alternative I should apply. At the moment, I really don't see a reason on why I would change this approach as it just works too well. I'm kinda stuck on this question because it just worries me sick as it seems to easy to be true. Why would people go through hard times if it would be as easy as this...

• jQuery is not defined

  - by dole

  Hi there, I have to use an external js file, in which I load the jquery. My js file look like this: document.write('<script language="javascript" type="text/javascript" src="http://code.jquery.com/jquery-1.4.4.min.js"></script>'); (function($) { $(document).ready(function() { alert('it works!!'); }); })(jQuery); On the firefox console I get the "jQuery is not defined" and I think it is because the jQuery library is loaded after the $ function from my js file. Do you have any idea about how can I fix this? If I run the script from the FF console all works fine.

My JS functions look like this: jQuery(document).ready(function() { alert('load test'); //ADMIN FUNCTION $('#mrc_imp_img').click(function(){ alert("test"); }); //FRONT END FUNCTION $("ul.mrc li").hover(function() { $(this).find('p').fadeIn(); } , function() { $(this).find('p').fadeOut(); }); }); The "load test"-alert is being loaded when the document is ready so jquery is properly loaded. The front end function is being used on pages and that's working fine to. the problem is the admin function, it's not working at all. is there a speial way i have to write a .click()-function to get it to work on my settings-page for the wordpress plugin?

• Seeking not working in HTML5 audio tag

  - by lord_wilmore

  I have a lighttpd server running locally. If I load a static file on the server (through an html5 audio tag), it plays and seeks fine. However, seeking doesn't work when running a dev server (web.py/CherryPy) or if I return the bytes via a defined action url instead of as a static file. It won't load the duration either. According to the "HTTP byte range requests" section in this Opera Page it's something to do with support for byte range requests/partial content responses. The content is treated as streaming instead. What I don't understand is: If the browser has the whole file downloaded surely it can display the duration, and surely it can seek. What I need to do on the web server to enable byte range requests (for non-static urls). Any advice would be most gratefully received.
