  • Want to set 'src' of script to my IP-Won't load in Safari or Chrome. Relative link asp.netmvc

    - by Ozaki
    I have a script that links to the server I am hosting (IP can change) usually I would just use for links: var url ='http://' + window.location.hostname + 'end of url'; But in this case it isnt appearing to be so easy. I have tried: (1) $('#scriptid').attr('src', url); as well as: (2) var script = document.createElement( 'script' ); script.type = 'text/javascript'; script.src = url; $("#insert").append( script ); Now case (2) works loads the script runs the script. But when at the end of my script it hits the 'write data' it decides to replace the entire page with just the data. Any idea on how I can do this? Note: I am using plain html not ASP. With ASP backend that is just the way it has to be. Ok it now is <script src="myscript.js"></script> C# router.AddAsyncRoute("myscript.js"...... It workes in IE & FF. But I get blank pages in Chrome & Safari. I am using document.write to write a script onto my page. Any ideas why Chrome & Safari don't like this? I am so far assuming that in Crhome & Safari it takes longer to run the script therefore launching the document.write after the DOM has loaded therefore replacing the page with a blank one. edit the script im trying to run is a modification of: d = new dTree('d'); d.add(0,-1,'My example tree'); d.add(1,0,'Node 1','default.html'); d.add(2,0,'Node 2','default.html'); d.add(3,1,'Node 1.1','default.html'); d.add(4,0,'Node 3','default.html'); d.add(5,3,'Node 1.1.1','default.html') document.write(d); Any ideas how I can get around this? I am not to sure how to implement an appenChild in this case as the script is changing constantly with live data. So every refresh it will generally have changed some...

  • Using PHP to read a web page with fsockopen(), but fgets is not working

    - by asdasd
    Im using this code here: http://www.digiways.com/articles/php/httpredirects/ public function ReadHttpFile($strUrl, $iHttpRedirectMaxRecursiveCalls = 5) { // parsing the url getting web server name/IP, path and port. $url = parse_url($strUrl); // setting path to '/' if not present in $strUrl if (isset($url['path']) === false) $url['path'] = '/'; // setting port to default HTTP server port 80 if (isset($url['port']) === false) $url['port'] = 80; // connecting to the server] // reseting class data $this->success = false; unset($this->strFile); unset($this->aHeaderLines); $this->strLocation = $strUrl; $fp = fsockopen ($url['host'], $url['port'], $errno, $errstr, 30); // Return if the socket was not open $this-success is set to false. if (!$fp) return; $header = 'GET / HTTP/1.1\r\n'; $header .= 'Host: '.$url['host'].$url['path']; if (isset($url['query'])) $header .= '?'.$url['query']; $header .= '\r\n'; $header .= 'Connection: Close\r\n\r\n'; // sending the request to the server echo "Header is: ".str_replace('\n', '\n', $header).""; $length = strlen($header); if($length != fwrite($fp, $header, $length)) { echo 'error writing to header, exiting'; return; } // $bHeader is set to true while we receive the HTTP header // and after the empty line (end of HTTP header) it's set to false. $bHeader = true; // continuing untill there's no more text to read from the socket while (!feof($fp)) { echo "in loop"; // reading a line of text from the socket // not more than 8192 symbols. $good = $strLine = fgets($fp, 128); if(!$good) { echo 'bad'; return; } // removing trailing \n and \r characters. $strLine = ereg_replace('[\r\n]', '', $strLine); if ($bHeader == false) $this-strFile .= $strLine.'\n'; else $this-aHeaderLines[] = trim($strLine); if (strlen($strLine) == 0) $bHeader = false; echo "read: $strLine"; return; } echo "after loop"; fclose ($fp); } This is all I get: Header is: GET / HTTP/1.1\r\n Host: www.google.com/\r\n Connection: Close\r\n\r\n in loopbad So it fails the fgets($fp, 128);

  • WPF performance for large number of elements on the screen

    - by Mark
    Im currently trying to create a Scene in WPF where I have around 250 controls on my screen and the user can Pan and Zoom in and out of these controls using the mouse. I have run the WPF Performance Suite tools on the application when there are a large number of these controls on the screen (i.e. when the user has zoomed right out) the FPS drops down to around 15 which is not very good. Here is the basic outline of the XAML: <Window> <Window.Resources> <ControlTemplate x:Key="LandTemplate" TargetType="{x:Type local:LandControl}"> <Canvas> <Path Fill="White" Stretch="Fill" Stroke="Black" StrokeThickness="1" Width="55.5" Height="74.687" Data="M0.5,0.5 L55,0.5 L55,74.187 L0.5,74.187 z"/> <Canvas x:Name="DetailLevelCanvas" Width="24.5" Height="21" Canvas.Left="15.306" Canvas.Top="23.972"> <TextBlock Width="21" Height="14" Text="712" TextWrapping="Wrap" Foreground="Black"/> <TextBlock Width="17.5" Height="7" Canvas.Left="7" Canvas.Top="14" Text="614m2" TextWrapping="Wrap" FontSize="5.333" Foreground="Black"/> </Canvas> </Canvas> </ControlTemplate> </Window.Resources> ... <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> ... and so on... </Window> Ive tried to minimise the details in the control template and I even did a massive find and replace of the controls to just put their raw elements inline instead of using a template, but with no noticeable performance improvements. I have seen other SO questions about this and people say to do custom drawing, but I dont really see how that make sense when you have to zoom and pan like I do. If anyone can help out here, that would be great! Mark

  • Css simple style dont work on IE but yes in any other browser

    - by DomingoSL
    Hello guys, i have a simple css file called Titulos.css who contain this: h1 { font: 50px Tahoma, Helvetica, Arial, Sans-Serif; text-align: center; color: #111; text-shadow: 0px 2px 3px #555; } h2 { font: 14px Tahoma, Helvetica, Arial, Sans-Serif; text-align: center; color: #CCC; text-shadow: 0px 1px 2px #555; } h3 { font: 10px Tahoma, Helvetica, Arial, Sans-Serif; text-align: center; color: #CCC; } b1 { font: 16px Tahoma, Helvetica, Arial, Sans-Serif; color: #DDD; } b2 { font: 10px Tahoma, Helvetica, Arial, Sans-Serif; color: #F9F7ED; } .caja { width: 690px; height: 40px; background-color: transparent; border: 0px solid #000000; font-size:x-large; color: #222; font-family: 'Trebuchet MS', 'Lucida Sans Unicode', 'Lucida Grande', 'Lucida Sans', Arial, sans-serif; font-weight: bold;" size="299"; } .style1 { text-align: right; } And a page who call this file like: <link rel="stylesheet" type="text/css" href="LIB/titulos.css" /> Later in this page im trying to use some of the styles like: <div id="todo" align="center" > <div id="cabeza" style="width:850px;height:100px"> </div> <div id="contenido" style="width:850px;height:420px;background-image: url(IMG/cuadro.png)" > <div id="titulo" style="width:765px;height:75px;padding-top: 18px;margin: auto;text-align: left;"> <b1>Bienvenido <b><?php echo($username); ?></b></b1><br> <?php $check = mysql_query("SELECT * FROM sms WHERE ref = '".$username."' ORDER BY fecha DESC LIMIT 0, 1") or die(mysql_error()); while($info = mysql_fetch_array( $check )) { echo("<b1> Tu ultimo mensaje enviado fue: </b1><b2>" . $info['texto'] . " enviado el " . $info['fecha'] . "</b2>"); That only a part of the code of course, the think is, Firefox and Chrome display the code above like this: that as you can see have the styles applied. But when i see the code from IE 8 (even 7 or 6) this is what you see: So, what do you think?

  • Help with css selector for jquery

    - by NachoF
    I have this wordpress blog that has many pages with subpages that dropdown on hover.... the thing is, I dont want the pages that you hover to link to anything unless they dont have any ul with many anchors inside so just the subpages will have a href different than "#" So basically Im hacking my way through this with some simple javascript. jQuery(document).ready(function(){ jQuery("#menus li > a").attr("href","#"); }); This is selecting every a.. and I dont want that... I just want the anchors that are main pages, not subpages... heres the html so maybe you can think of a better way to select this. Ill explain first the structure is an ul with many li that have an anchor inside if the li also has a ul inside then those are subpages that will appear on hover. hence the initial anchor should have href="#" if there is no ul inside the li then the li a should keep its href. <ul id="menus"> <li> <a href="somelink">Main Page</a> //href should be changed to # <ul> <li> <a href="somelink2/">Subpage1</a> </li> <li> <a href="somelink3">Subpage2</a> </li> </ul> </li> <li> <a href="somelink">MainPage-with-no-subpages</a> //href should not be changed </li> <li> <a href="somelink4">MainPage</a> //href should be changed to # <ul> <li> <a href="somelink5">Subpage</a> </li> <li> <a href="somelink6">Subpage</a> </li> </ul> </li> </ul>

  • Audio/video streaming on Windows platform

    - by bushtucker
    I'm building an interactive language learning application to be used in a classroom environment. The idea is that a teacher should be able to talk to the students (=audio stream to all students), let students talk to each other (= audio P2P) in groups of two or more, let students watch a video coming from a the DVD player or coming from a media server. It should be possible to save the audio/video streams. The teacher should also be able to monitor, take-over or block the desktop of the students. The platform is Windows and it's a desktop application, no web application. The audio delay should be as minimal as poosible. Optionally a student sitting at home should be supported, but it's not a high priority. I am now finished with the classroom control part of the application (login, monitor, block, ...) and want to start the audio and video part. I've been evaluating several options like DirectX, GStreamer and SIP but now I have to make a decision. DirectX seems an obvious choice for the Windows platform, but it only lets me capture and playback audio and video. The encoding/decoding/network part I should do myself. GStreamer contains all kinds of options to capture/encode/stream/save audio and video streams. I've experimented a bit with it (ossbuild) and it does seem to involve a lot of trial and error to make something work: - microphone capture (via directsoundsrc) produces cracking noises on some computers - rtpL16 payloader didn't work well - streaming raw audio over the network only working at a sampling rate of 8000, no higher - there are a lot of errors when receiving mpeg4 video (bad I-frame), on some computers worse than others It is my impression that gstreamer is primary targetted at linux platforms. Development and support for the Windows platform seems to be a little behind. Nevertheless it's a powerful framework that could save me months and years of work. SIP seems to be able to do everything I want, but it is targeted towards telephony and IM. I don't know how flexible SIP is. It seems to me that the SIP layer would just be overhead as I already have a central (teacher) application that can control and setup all the streams. The interesting parts of frameworks like opalvoip and freeswitch are the actual audio/video capture, the encoding and transmission. Does anyone know how these interesting parts relate a framework like gstreamer? Are they easy to integrate into a custom application? Are they flexible enough? Does anyone have experience with all or one of these technologies? Maybe there are even other options I can look at? Many thanks for your advice

  • unable to capture picture using camera in j2me polish?

    - by SIVAKUMAR.J
    I'm, developing a mobile app in j2me.Now im converting it into j2me polish. In my app I capture a picture using camera in mobile phone. It works fine in j2me. But it does not work fine in j2me polish. I cannot resolve it. The code snippet given below public class VideoCanvas extends Canvas { // private VideoMIDlet midlet; // Form frm Form frm=null; public VideoCanvas(VideoControl videoControl) { int width = getWidth(); int height = getHeight(); // this.midlet = midlet; //videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO, this); //Canvas canvas = StyleSheet.currentScreen; //canvas = MasterCanvas.instance; videoControl.initDisplayMode( VideoControl.USE_DIRECT_VIDEO,this); try { videoControl.setDisplayLocation(2, 2); videoControl.setDisplaySize(width - 4, height - 4); } catch (MediaException me) {} videoControl.setVisible(true); } public VideoCanvas(VideoControl videoControl,Form ff) { frm=ff; int width = getWidth(); int height = getHeight(); // this.midlet = midlet; Ticker ticker=new Ticker("B4 video controll init"); frm.setTicker(ticker); //Canvas canvas = StyleSheet.currentScreen; videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO,this); ticker=new Ticker("after video controll init"); frm.setTicker(ticker); try { videoControl.setDisplayLocation(2, 2); videoControl.setDisplaySize(width - 4, height - 4); } catch (MediaException me) {} videoControl.setVisible(true); ticker=new Ticker("Device not supported"); frm.setTicker(ticker); } public void paint(Graphics g) { int width = getWidth(); int height = getHeight(); g.setColor(0x00ff00); g.drawRect(0, 0, width - 1, height - 1); g.drawRect(1, 1, width - 3, height - 3); } } In normal j2me the above code works correctly. But in j2me polish videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO,this) here this refers to VideoCanvas (which extends from javax.microedition.lcdui.Canvas). But it throws an "IllegalArgumentException - container should be canvas" like that. How to solve the issue?

I am sorry that I can not explain it better.

  • Rails 3 - development errors in production mode

    - by skrafi
    Im using Rails, Passenger (both are 3.0.5) and Nginx on my production server. As I heard, Rails should show public/404.html or public/500.html instead of development errors like ActiveRecord::RecordNotFound or Unknown action but that doesn't happen. I've tried to delete config.ru file and set rack_env or rails_env in nginx.conf but nothing helped. Here is my nginx.conf: worker_processes 1; events { worker_connections 1024; } http { passenger_root /home/makk/.rvm/gems/ruby-1.9.2-p0/gems/passenger-3.0.5; passenger_ruby /home/makk/.rvm/bin/passenger_ruby; #passenger_ruby /home/makk/.rvm/wrappers/ruby-1.9.2-p0/ruby; include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name localhost; location / { root /home/makk/projects/1server/deploy/current/public; index index.html index.htm; passenger_enabled on; rack_env production; recursive_error_pages on; if (-f /home/makk/projects/1server/maintenance.html) { return 503; } error_page 404 /404.html; error_page 500 502 504 /500.html; error_page 503 @503; } location @503 { error_page 405 = /maintenance.html; # Serve static assets if found. if (-f $request_filename) { break; } rewrite ^(.*)$ /maintenance.html break; } location ~ ^(\/phpmyadmin\/)(.*)$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_split_path_info ^(\/phpmyadmin\/)(.*)$; fastcgi_param SCRIPT_FILENAME /usr/share/phpmyadmin/$fastcgi_path_info; include fastcgi_params; } } } It seems that this question duplicates this one but there are no working suggestions. UPD: I have both development and production apps on same PC. In production Rails ignores config.consider_all_requests_local = false (in /config/environments/production.rb) due to local_request? method. So one of possible solutions is listed below (taken from here): # config/initializers/local_request_override.rb module CustomRescue def local_request? return false if Rails.env.production? || Rails.env.staging? super end end ActionController::Base.class_eval do include CustomRescue end Or for Rails 3: class ActionDispatch::Request def local? false end end

  • asp.net custom templated datalist - throws argument out of range (index) on button press

    - by MrTortoise
    I have a class BaseTemplate public abstract class BaseTemplate : ITemplate This adds the controls, and provides abstract methods to implement in the inheriting class. The inheriting class then adds its html according to its data source and manages the data binding. this all works fine - I get the control appearing with properly parsed html. the problem is that the base class adds controls into the template that have their own CommandName arguments ... the idea is that the class that implements the custom templated dataList will provide the logic of setting the Selected and Edit Indexes. This class also manages the data binding etc. It sets all of the templates ont he datalist in the Init method (which was another cause of this exception). the exception gets throw when i hit one of these buttons .. but after the ItemCommand event is being processed. The stack trace does not include any references to my methods or objects which is why i am so stuck.

  • My mental block - struggling to learn Objective C

    - by iqessar
    Hello people, this would be my first question after signing up! Anyway heres my question, I did Java at university and I was always told I am a good programmer. However I never pursued it as a career - I went into support and management instead. Im pretty much bored with my job, I have therefore started to learn Objective C so that I can develop apps for the iphone. I am currently watching several different Videos / Books. My problem is that when I go through the Apple documentation, although I understand most of it, sometimes I stumble. I believe that because you/we have the Apple documentation (i.e. Framework references) , everything should be clear, and therefore you should have no need to refer to a book or video (in order to learn how to use a particular class). But I alway do refer to a book and video and subsequently feel guilty as I believe the framework reference should be enough. (I therefore feel I am not up to being a programmer) I also believe that you shouldn't need example code in order to learn how to use a particular class because Apple provides documentation for each class, but AGAIN I find my self googling example code and I find my answer like that - again I feel guilty for doing this. Am I right in saying that Apple documentation is simply not clear? and that its ok to refer to a video/book or google? or forums for that matter? I have proffesional programmers who tell me that I am worrying too much and that I should get on with it and use all the resources that I have. I just cant seem to get round this mental block that I have in my head. When I start a programming project I am able to use the excellent search skills that I have to find the code I need, copy and paste it (yes I do understand it) BUT then I feel guilty telling myself that why didn't you think up the code yourself???? Therefore your not a real programmer, your just good at googling. Currently I am going through 20+ books so that I can learn most of the frameworks, syntax etc to develop iphone apps. I believe if I do this, then when I think of a project I can make it quickly. Should I read a few books, like 2-3 and then just start a project /app , and if I get stuck just google it and get the code I need? Can anybody please answer my questions?

    I have a small application where i need to navigate to an url, I use this method to get the Frame: public override System.Windows.UIElement GetPage(System.Windows.UIElement container) { XmlDocument doc = new XmlDocument(); doc.Load(Location); string webSiteUrl = doc.SelectSingleNode("website").InnerText; Frame newFrame = new Frame(); if (!webSiteUrl.StartsWith("http://")) { webSiteUrl = "http://" + webSiteUrl; } newFrame.Source = new Uri(webSiteUrl); return newFrame; } My problem is now that the page im trying to show generates a error (or so i think), when i load the page in a browser it never fully loads, keeps saying "loading1 element" in the load bar and the green progress line (IE 8) keeps showing.

  • clarification on the concept of "web service"

    - by udit
    Im a little confused on the varying definitions and implementations of web services available as implementations. Need some clarification please. Ones I have used till now: If a vendor gives me a specific format of XML that I can send populated with data to request and I make a simple HTTP POST over the internet passing in the XML String as the payload, is this a web service call ? If so, is there a specific name to it, this kind of web service ? Because obviously, it does not use anything like Axis, WSDL or SOAP to establish this connection. A variant of this is If the vendor gives me an XSD, I use JAXB to make a java class out of it and pass in the serialized version of the object, which eventually works out to be the same as option 1. RESTful web service: Vendor gives me a URL like http://restfulservice/products and I can make HTTP Requests to the URL and depending on what HTTP verb I use, the appropropriate action is called and the response sent over the wire. Ones I have only read about\ have a vague idea about SOAP. How does this work?.. Ive read the W3Schools tutorial and I undertsand that there is a very specific form of XML that is standardized according to W3C standards that we use to pass the same kind of messages as we did in option 1. But how does this work in real life? Vendor sends me what? Do I generate classes? Do I serialize some objects and http post them over to an address? Or do the generated objects themselves have connection methods that will do them for me? What about WSDL? When does a vendor send me WSDL and what do I do with it ? I guess I can generate classes from it. If yes, then what do I do with the generated classes ? When do I need that axis jar to generate classes from something that the vendor sends ? As you can see, I have some clear and other mostly vague ideas about the different kinds of web services available. would help if someone ould clarify and\or point to more real-world resources. I've looked a little bit into Java Web Services on the internet and the numerous four letter acronyms that get thrown at me make me dizzy. Thanks

  • importing modules in app engine

    - by tanky
    Ive asked this before, but it seems i wasnt clear/detailed enough and after a week of trying im still struggling so i will try again. i am trying to use, oauth2 and ply on app engine. i have tried copying their directories into my app engine project directory (in the form ply-3.4 or brosner-python-oauth2-82a05f9) and i have tried copying the specific sub directory contained within the aforemention one. (ply or oauth2) i have tried saying import oauth2, from brosner-oauth2_python-82a05f9 import oauth and other variations on the theme, but i still cant get it to work nothing has worked. i have tried including them in app.yaml, but that seemed to create an even bigger error as my entire project wouldnt even run when i tried that. and now i have run out of things to try. the error log i am getting is as follows.

  • initializing a vector of custom class in c++

    Hey basically Im trying to store a "solution" and create a vector of these. The problem I'm having is with initialization. Heres my class for reference class Solution { private: // boost::thread m_Thread; int itt_found; int dim; pfn_fitness f; double value; std::vector<double> x; public: Solution(size_t size, int funcNo) : itt_found(0), x(size, 0.0), value(0.0), dim(30), f(Eval_Functions[funcNo]) { for (int i = 1; i < (int) size; i++) { x[i] = ((double)rand()/((double)RAND_MAX))*maxs[funcNo]; } } Solution() : itt_found(0), x(31, 0.0), value(0.0), dim(30), f(Eval_Functions[1]) { for (int i = 1; i < 31; i++) { x[i] = ((double)rand()/((double)RAND_MAX))*maxs[1]; } } Solution operator= (Solution S) { x = S.GetX(); itt_found = S.GetIttFound(); dim = S.GetDim(); f = S.GetFunc(); value = S.GetValue(); return *this; } void start() { value = f (dim, x); } /* plus additional getter/setter methods*/ } Solution S(30, 1) or Solution(2, 5) work and initalizes everything, but I need X of these solution objects. std::vector<Solution> Parents(X) will create X solutions with the default constructor and i want to construct using the (int, int) constructor. Is there any easy(one liner?) way to do this? Or would i have to do something like: size_t numparents = 10; vector<Solution> Parents; Parents.reserve(numparents); for (int i = 0; i<(int)numparents; i++) { Solution S(31, 0); Parents.push_back(S); }

  • web service filling gridview awfully slow, as is paging/sorting

    Hi I am making a page which calls a web service to fill a gridview this is returning alot of data, and is horribly slow. i ran the svcutil.exe on the wsdl page and it generated me the class and config so i have a load of strongly typed objects coming back from each request to the many service functions. i am then using LINQ to loop around the objects grabbing the necessary information as i go, but for each row in the grid i need to loop around an object, and grab another list of objects (from the same request) and loop around each of them.. 1 to many parent object child one.. all of this then gets dropped into a custom datatable a row at a time.. hope that makes sense.... im not sure there is any way to speed up the initial load. but surely i should be able to page/sort alot faster than it is doing. as at the moment, it appears to be taking as long to page/sort as it is to load initially. i thought if when i first loaded i put the datasource of the grid in the session, that i could whip it out of the session to deal with paging/sorting and the like. basically it is doing the below protected void Page_Load(object sender, EventArgs e) { //init the datatable //grab the filter vars (if there are any) WebServiceObj WS = WSClient.Method(args); //fill the datatable (around and around we go) foreach (ParentObject po in WS.ReturnedObj) { var COs = from ChildObject c in WS.AnotherReturnedObj where c.whatever.equals(...) ...etc foreach(ChildObject c in COs){ myDataTable.Rows.Add(tlo.this, tlo.that, c.thisthing, c.thatthing, etc......); } } grdListing.DataSource = myDataTable; Session["dt"] = myDataTable; grdListing.DataBind(); } protected void Listing_PageIndexChanging(object sender, GridViewPageEventArgs e) { grdListing.PageIndex = e.NewPageIndex; grdListing.DataSource = Session["dt"] as DataTable; grdListing.DataBind(); } protected void Listing_Sorting(object sender, GridViewSortEventArgs e) { DataTable dt = Session["dt"] as DataTable; DataView dv = new DataView(dt); string sortDirection = " ASC"; if (e.SortDirection == SortDirection.Descending) sortDirection = " DESC"; dv.Sort = e.SortExpression + sortDirection; grdListing.DataSource = dv.ToTable(); grdListing.DataBind(); } am i doing this totally wrongly? or is the slowness just coming from the amount of data being bound in/return from the Web Service.. there are maybe 15 columns(ish) and a whole load of rows.. with more being added to the data the webservice is querying from all the time any suggestions / tips happily received thanks

    - by Frederik Wessberg
    Hey Folks. I've read what I could, and I'm certainly no master, but I'm fixing up a colleagues profile on myspace.com, and im working with 2 divs in each side of the screen, and I want them to align so that they are next to each other. I've tried float: left; and float: right;, and I've tried margin: right; on div 1 and such. Could you help? Here's the site: http://www.myspace.com/jonasjohansen This is info for div1: <div class="textBox" align="left" style="width: 290px; word-wrap:break-word"> <span class="orangetext15"> BANDS </span> <b>MOVE</b><br /> Fredrik ....balbalbalbla </div> <style> .textBox { position: relative; left:-320px; top:0px; width: 290px; height: 350px; overflow-y: visible; overflow-x: visible; top: YYYpx; z-index: 3; background-color: transparent; border:none; } </style> This is info for div2: <style>.i {display:none;}{!-eliminate bio header!-}table table td.text table td.text {display:none;}{!-recover in shows and friends-!}table table td.text div table td.text,table table td.text table.friendSpace td.text {display:inline;}{! move up our custom section.

  • HttpWebRequest possibly slowing website

    - by Steven Smith
    Using Visual studio 2012, C#.net 4.5 , SQL Server 2008, Feefo, Nopcommerce Hey guys I have Recently implemented a new review service into a current site we have. When the change went live the first day all worked fine. Since then though the sending of sales to Feefo hasnt been working, There are no logs either of anything going wrong. In the OrderProcessingService.cs in Nop Commerce's Service, i call a HttpWebrequest when an order has been confirmed as completed. Here is the code. var email = HttpUtility.UrlEncode(order.Customer.Email.ToString()); var name = HttpUtility.UrlEncode(order.Customer.GetFullName().ToString()); var description = HttpUtility.UrlEncode(productVariant.ProductVariant.Product.MetaDescription != null ? productVariant.ProductVariant.Product.MetaDescription.ToString() : "product"); var orderRef = HttpUtility.UrlEncode(order.Id.ToString()); var productLink = HttpUtility.UrlEncode(string.Format("myurl/p/{0}/{1}", productVariant.ProductVariant.ProductId, productVariant.ProductVariant.Name.Replace(" ", "-"))); string itemRef = ""; try { itemRef = HttpUtility.UrlEncode(productVariant.ProductVariant.ProductId.ToString()); } catch { itemRef = "0"; } var url = string.Format("feefo Url", login, password,email,name,description,orderRef,productLink,itemRef); var request = (HttpWebRequest)WebRequest.Create(url); request.KeepAlive = false; request.Timeout = 5000; request.Proxy = null; using (var response = (HttpWebResponse)request.GetResponse()) { if (response.StatusDescription == "OK") { var stream = response.GetResponseStream(); if(stream != null) { using (var reader = new StreamReader(stream)) { var content = reader.ReadToEnd(); } } } } So as you can see its a simple webrequest that is processed on an order, and all product variants are sent to feefo. Now: this hasnt been happening all week since the 15th (day of the implementation) the site has been grinding to a halt recently. The stream and reader in the the var content is there for debugging. Im wondering does the code redflag anything to you that could relate to the process of website? Also note i have run some SQL statements to see if there is any deadlocks or large escalations, so far seems fine, Logs have also been fine just the usual logging of Bots. Any help would be much appreciated! EDIT: also note that this code is in a method that is called and wrapped in A try catch UPDATE: well forget about the "not sending", thats because i was just told my code was rolled back last week

  • how to change color of text following function in javascript

    - by OVERTONE
    Ok before i make spaghetti of this code i thought id ask around here. ive made a quiz for an online site. The answers are stored in an array, and ive a function that checks the answers array to what youve clicked. then it counts them and gives you your score. but i want to change the clor of the right answer wen the user clicks the score button. so the correct answers are highlighted. something like this https://www.shutterpoint.com/Home-Quiz.cfm (just hit submit at the bottom, no need to do the quiz). the little answer icon at the side looks flashy but id rather just have the text change color. heres how my questions are formatted <p>Depth of field is controlled by :?</p> <p id = "question2"><input type="radio" name="question2" id="Answer1" value = "a" onClick ="recordAnswer(2,this.value)"/> The focal length of the lens. <br/> <input type="radio" name="question2" id="Answer2" value = "b" onClick = "recordAnswer(2,this.value)"/> The size of the aperture opening. <br/> <input type="radio" name="question2" id="Answer3" value = "c" onClick = "recordAnswer(2,this.value)"/> The distance between the camera and lens. <br/> <input type="radio" name="question2" id="Answer4" value = "d" onClick = "recordAnswer(2,this.value)"/> All of these. <br/></p> and these are the two functions that are called throughout. record answer is called every time the user clicks a button function recordAnswer(question,answer) { answers[question-1] = answer; } this is the final button which calculates the score function scoreQuiz() { var totalCorrect = 0; for(var count = 0; count<correctAnswers.length;count++) { if(answers[count]== correctAnswers[count]) totalCorrect++; } <!-- alert("You scored " + totalCorrect + " out of 12 correct!"); --> } another function is best i think. ive already made attemots at it and know i have to set the color using document.getElementById('question2').style.color = '#0000ff'; question2 being the p id i think if i take in the value part of (input type....) ill be able to compare it to the answers array. but im not quite sure how to do this. any helpers? maybe something like this document.getElementById("Answer1").style.color = '#0000ff'; using the id part of the (input type line) i think i got it actually. ill post my answer in a sec
