  • post to actionrequest from an anchor

    - by griegs
    I have the following; <% using(Html.BeginForm("GetRecommendedProducts", "Home", FormMethod.Post)) { %> <% Html.RenderPartial("QuickQuote", Model.quickQuote); %> <div class="But brown" style="float:left;"> <a href="." onclick="$.unblockUI(); return false;">Close</a> </div> <div class="But green" style=""> <a href="." onclick="this.form.submit(); return false;">Go</a> </div> <%} %> When I click the anchor I do not get a post to my action. I know this should be possible so what am I doing wrong? The partial view only contains fields and not another BeginForm or anything like that. If I use a submit button it works ok but I can't use a submit button I need to use an anchor.

  • QueryReadStore loads JSON into DataGrid, but JsonRestStore does not (from the same source)

    - by labratmatt
    I'm building a Dojo DataGrid from JSON data provided by my REST interface. The DataGrid loads the data fine using a QueryReadStore, but doesn't seem to work with the same same data piped into a JsonRestStore. I'm using the following Dojo libs with Dojo 1.4.1: dojo.require("dojox.data.JsonRestStore"); dojo.require("dojox.grid.DataGrid"); dojo.require("dojox.data.QueryReadStore"); dojo.require("dojo.parser"); I declare my stores in the following manner: var storeJRS = new dojox.data.JsonRestStore({target:"api/collaborations.php/1", idAttribute: 'items[].id'}); var storeQRS = new dojox.data.QueryReadStore({url:"api/collaborations.php/1", requestMethod:"get"}); I create my grid layout like this: var gridLayout = [ new dojox.grid.cells.RowIndex({ name: "Row #", width: 5, styles: "text-align: left;" }), { name: "Name", field: "name", styles: "text-align:right;", width:20 }, { name: "Description", field: "description", width:30 } ]; I create my DataGrid as follows: The above works, but if I use QueryReadStore as my store, the grid is created with the headers (Name, Description), but it isn't populated with any rows: <div dojoType="dojox.grid.DataGrid" jsid="grid3" store="storeQRS" structure="gridLayout" style="height:500px; width:1000px;"></div> Using FireBug, I can see that QueryReadStore is getting my JSON data from my REST interface. It looks like the following: {"numRows":6,"items":[{"name":"My Super Cool Collab","description":"This is for all the super cool people in the super cool group","id":1},{"name":"My Other Super Cool","description":"This is for all the other super cool people","id":3},{"name":"This is another coll","description":"This is just some other collab","id":4},{"name":"some new collab","description":"this is a new collab","id":5},{"name":"yet another new coll","description":"uh huh","id":6},{"name":"asdf","description":"asdf","id":7}]} Any ideas? Thanks.

  • MATLAB only prints a part of my figure

    - by simonty
    I'm trying to print my figure in Matlab, but it keeps screwing up and I have no idea why. opslaan = figure(1); plot(1:handles.aantal,handles.nauw,'-r','LineWidth',1.5); xlabel(gca,sprintf('Framenummer (%g ms per frame)',60/handles.aantal)); ylabel(gca,'dB'); set(gca,'YGrid','on'); yAsMax = ceil( ceil(max(handles.nauw)) / 2) * 2; axis([0 handles.aantal 0 yAsMax]); pause(1); print -dpng image.png The first line is just plotting the data on my figure, then labeling x and y, turning on grid and caculating the y-axis like I want it. This all works great and Matlab shows it like I want it in the Figure window. When saving to .png / .jpeg / .eps it goes wrong and only prints the bottom left corner (473x355 pixels), the rest just disappeared. When exporting manually via File - Save As, it works correctly. Any help? Thanks!

  • storing/retrieving data for graph with long continuous stretches

    - by james
    i have a large 2-dimensional data set which i would like to graph. the graph is displayed in a browser and the data is retrieved via ajax. long stretches of this graph will be continuous - e.g., for x=0 through x=1000, y=9, then for x=1001 through x=1100, y=80, etc. the approach i'm considering is to send (from the server) and store (in the browser) only the points where the data changes. so for the example above, i would say data[0] = 9, then data[1001] = 80. then given x=999 for example, retrieving data[999] would actually look up data[0]. the problem that arises is finding a dictionary-like data structure which behaves like this. the approach i'm considering is to store the data in a traditional dictionary object, then also maintain a sorted array of key for that object. when given x=999, it would look at the mid-point of this array, determine whether the nearest lower key is left or right of that midpoint, then repeat with the correct subsection, etc.. does anyone have thoughts on this problem/approach?

  • Absolute positioned div jumps outside containing div in IE7

    - by user367232
    Having trouble with a couple of display issues in IE7. Firstly, my large text headers display too far up in Internet Explorer (all pages) Secondly, my descriptions on my Portfolio pages end up outside their containing divs. Works great on FF/Chrome/Opera/Safari though! You'll see what I mean: http://bit.ly/a3hUD4 (I've used bitly so my dumb questions don't show up when someone googles my website). I've googled extensively. Not sure if problem number 2 is a overflow issue, or a absolute positioning bug in IE. Here's the CSS for the centre div with the jumbo-text titles .column1 { padding: 103px 10px 10px 10px; float: left; width: 500px; margin: 0; } And for the description div on the portfolio page .porttxtbox { text-align: right; background-image: url(images/porttxtBG.png); bottom: 0; position: absolute; width: 100%; padding: 0px; margin: 0px; } And it's container div .portimgbox { padding: 0px; margin: 0px; height: 250px; width: 480px; position: relative; border: 5px solid #EAEAEA; Thanks in advance!

  • Encoding MySQL text fields into UTF-8 text files - problems with special characters

    - by Matt Andrews
    I'm writing a php script to export MySQL database rows into a .txt file formatted for Adobe InDesign's internal markup. Exports work, but when I encounter special characters like é or umlauts, I get weird symbols (eg Chloë Hanslip instead of Chloë Hanslip). Rather than run a search and replace for every possible weird character, I need a better method. I've checked that when the text hits the database, it's saved properly - in the database I see the special characters. My export code basically runs some regular expressions to put in the InDesign code tags, and I'm left with the weird symbols. If I just output the text to the browser (rather than prompt for a text file download), it displays properly. When I save the file I use this code: header("Content-disposition: attachment; filename=test.txt"); header("Content-Type: text/plain; charset=utf-8"); I've tried various combinations of utf8_encode() and iconv() to no avail. Can anybody point me in the right direction here?

  • How to use the Request URL/URL Rewriting For Localization in ASP.NET - Using an HTTP Module or Globa

    - by LocalizedUrlDMan
    I wanted to see if there is a way to use the request URL/URL rewriting to set the language a page is rendered in by examining a portion of the URL in ASP.NET. We have a site that already works with ASP.NET’s resource localization and user’s can change the language that they see pages/resources on the site in, however the current mechanism in not very search engine friendly since the language variations for each language all appear as one page. It would be much better if we could have pages like www.site.com/en-mx/realfolder/realpage.aspx that allow linking to culture specific versions of a page. I know lots of people have likely done localization through URL structures before and I wanted to know if one of your could share how to do this in the Global.asax file or with an HTTP Module (pointing to links to blog postings would be great too). We have a restriction that the site is based on ASP.NET 2.0 (so we can't used the 3.5+ features yet). Here is the example scenario: A real page exits at: www.site.com/realfolder/realpage.aspx The page has a mechanism for the user to change the language it is displayed in via a dropdown. There are search engine optimization and user links sharing benefits to doing this since people can link directly to a page that has content that is applicable to a certain language (this could also include right-to-left layouts for languages like Japanese). I would like to use an HTTP module to see if the first part of the URL after www.site.com, site.com, subdomain.site.com, etc. contains a valid culture code (e.g. en-us, es-mx) then use that value to set the localization culture of the page/resources based on that URL. So if the user accesses the URL www.site.com/en-MX/realfolder/realpage.aspx Then the page will render in Mexico’s variant of Spanish. If the user goes to www.site.com/realfolder/realpage.aspx directly the page would just use their browser’s language settings.

  • Boost::Mutex & Malloc

    - by M. Tibbits
    Hi all, I'm trying to use a faster memory allocator in C++. I can't use Hoard due to licensing / cost. I was using NEDMalloc in a single threaded setting and got excellent performance, but I'm wondering if I should switch to something else -- as I understand things, NEDMalloc is just a replacement for C-based malloc() & free(), not the C++-based new & delete operators (which I use extensively). The problem is that I now need to be thread-safe, so I'm trying to malloc an object which is reference counted (to prevent excess copying), but which also contains a mutex pointer. That way, if you're about to delete the last copy, you first need to lock the pointer, then free the object, and lastly unlock & free the mutex. However, using malloc to create a boost::mutex appears impossible because I can't initialize the private object as calling the constructor directly ist verboten. So I'm left with this odd situation, where I'm using new to allocate the lock and nedmalloc to allocate everything else. But when I allocate a large amount of memory, I run into allocation errors (which disappear when I switch to malloc instead of nedmalloc ~ but the performance is terrible). My guess is that this is due to fragmentation in the memory and an inability of nedmalloc and new to place nice side by side. There has to be a better solution. What would you suggest?

  • Returning a Value From the Bit.ly JS API Callback

    - by mtorbin
    Hey all, I am attempting to turn this "one shot" script into something more extensible. The problem is that I cannot figure out how to get the callback function to set a value outside of itself (please note that references to the Bit.ly API and the prototype.js frame work which are required have been left out due to login and apiKey information): CURRENTLY WORKING CODE var setShortUrl = function(data) { var resultOBJ, myURL; for(x in data.results){resultOBJ = data.results[x];} for(key in resultOBJ){if(key == "shortUrl"){myURL = resultOBJ[key];}} alert(myURL); } BitlyClient.shorten('http://www.thinkgeek.com', 'setShortUrl'); PROPOSED CHANGES var setShortUrl = function(data) { var resultOBJ, myURL; for(x in data.results){resultOBJ = data.results[x];} for(key in resultOBJ){if(key == "shortUrl"){myURL = resultOBJ[key];}} alert(myURL); return myURL; } var myTEST = BitlyClient.shorten('http://www.thinkgeek.com', 'setShortUrl'); alert(myTEST); As you can see this doesn't work the way I'm am expecting. If I could get a pointer in the right direction it would be most appreciated. Thanks, MT

  • when updating location.hash in Chrome the jQuery animation "freezes" for a second

    - by ubunut
    I'm trying to create a sort of "virtual gallery". I'm using Coda Slider 2.0 & jQuery v1.4.2 It behaves perfectly in IE, FF & Safari, but Chrome seems to reload/hang for a second when setting location.hash. This causes the jQuery animation to freeze for a second :S Example: http://hardyernst.dk/gallery.html try clicking on the navigation links above the pictures. The jQuery code that is being executed when clicking a navigation link: $('#coda-nav-' + sliderCount + ' a').each(function(z) { // What happens when a nav link is clicked $(this).bind("click", function() { offset = -(panelWidth*z); navClicks++; $(this).addClass('current').parents('ul').find('a').not($(this)).removeClass('current'); alterPanelHeight(z); currentPanel = z + 1; $('.panel-container', slider).stop().animate({ left: offset }, settings.slideEaseDuration, settings.slideEaseFunction, function(){ if (!settings.crossLinking) { return false; } // Don't change the URL hash unless cross-linking is specified }); }); }); if I add return false; at the end of the function. The animation will slide smoothly :)... BUT as you might have guessed the location.hash value remains unchanged :( I have tried setting the location.hash earlier in the function alas it did not change the behavior in Chrome Would be immensely grateful for any help :) Regards Ubunut

  • CSS buttons and crossbrowser issue

    - by Jason
    I have a class 'button' that I want to use for button, input and a tags. The problem is that both button and input tags have a greater line height than the anchor tag does. I have attached an example here so you can play around with it in firebug or whatever. http://28dev.com/stackoverflow/css-buttons.html But for those who just want to see the css/html, here it is: .button { font-family : helvetica, arial, sans-serif; -moz-border-radius: 3px; -webkit-border-radius: 3px; background : url(/images/ui-bg_glass_75_e6e6e6_1x400.png) repeat-x scroll 50% 50% #E6E6E6; border-color : #636363 #888888 #888888 #636363; border-right : 1px solid #888888; border-style : solid; border-width : 1px; cursor : pointer; display : block; float : left; font-size : 12px; font-weight : normal; line-height : 100%; min-width : 100px; padding : 3px 12px; text-align : center; } .button, .button a { color : #282828; text-decoration : none; } .button:hover, .button:hover a { border-color : #343434; color : #080808; } .marginR { margin-right : 5px; } <button class='button marginR' type='submit'>button.button</button> <input type="submit" value="input.button" class="button marginR" /> <a class="button" href="">a.button</a>

  • Windows 7 DWM weirdness

    - by Max
    I'm looking to write a FOSS "Alt+Tab" replacement (window switcher) for Windows, since there are a few features I feel it's (still) lacking; but I'm noticing two quirks I can't seem to fix: #1. (Somewhat Unrelated) In the default Windows 7 window switcher, one computer allows left clicking on a thumbnail to focus the window; however on another, similarly specced computer, I have to use a right click. The only difference between these two fresh installs is the theme. Any ideas? #2. (Directly Related) In both the default Windows 7 window switcher and the DWM API output, minimized windows often have no thumbnail, and instead show only the taskbar. This has been a long running problem with the Windows API, and in the past I've seen the popular recommendation being "restore (un-minimize) the window, take a screenshot, then re-minimize" - but this is sloppy and causes flickering, etc. Has anyone done this successfully using the newer DWM API? If sharing code, I'd prefer C# syntax, but VB.NET will do as well. Thanks!

  • Combining data sets without losing observations in SAS

    - by John
    Hye guys, I know, another post another problem :D :(. I took a screenshot to easily explain my problem. http://i39.tinypic.com/rhms0h.jpg As you can see I want to merge two tables (again), the Base & Analyst table. What I want to achieve is displayed in the right bottom corner table. I’m calculating the number of total analysts and female analysts for each month in the analyst table. In the base table I have different observations for one company (here company Alcoa with ticker AA). When I use the following command: data want; merge base analyst; by month ; run; I get the right up corner problem. My observations in the main table are being narrowed down to only 4 observations (for each different year one observation, 2001, 2002, 2005, 2006). What I want is that the observations are not reduced but that for every year the same data is being placed as shown in the right bottom corner. What am I missing in my merge command? In both tables I have month as a time count variable ( the observations in my base table are monthly) on which I need to merge. For clarity I added 2 screenshots of my real databases in SAS. The base table: http://i42.tinypic.com/dr5jky.jpg The analyst table: http://i40.tinypic.com/eqpmqq.jpg Here is what my merged table looks like: http://i43.tinypic.com/116i62s.jpg You can clearly see that the merged table only has four observations left for AA (one for each unique year) instead of the original 8. Anyone an idea to solve this?

  • Android - Dealing with a Dialog on Screen Orientation change

    - by Donal Rafferty
    I am overriding the onCreateDialog and onPrepareDialog methods or the Dialog class. I have followed the example from Reto Meier's Professional Android Application Development book, Chapter 5 to pull some XML data and then use a dialog to display the info. I have basically followed it exactly but changed the variables to suit my own XML schema as follows: @Override public Dialog onCreateDialog(int id) { switch(id) { case (SETTINGS_DIALOG) : LayoutInflater li = LayoutInflater.from(this); View settingsDetailsView = li.inflate(R.layout.details, null); AlertDialog.Builder settingsDialog = new AlertDialog.Builder(this); settingsDialog.setTitle("Provisioned Settings"); settingsDialog.setView(settingsDetailsView); return settingsDialog.create(); } return null; } @Override public void onPrepareDialog(int id, Dialog dialog) { switch(id) { case (SETTINGS_DIALOG) : String afpunText = " "; if(setting.getAddForPublicUserNames() == 1){ afpunText = "Yes"; } else{ afpunText = "No"; } String Text = "Login Settings: " + "\n" + "Password: " + setting.getPassword() + "\n" + "Server: " + setting.getServerAddress() + "\n"; AlertDialog settingsDialog = (AlertDialog)dialog; settingsDialog.setTitle(setting.getUserName()); tv = (TextView)settingsDialog.findViewById(R.id.detailsTextView); if (tv != null) tv.setText(Text); break; } } It works fine until I try changing the screen orientation, When I do this onPrepareDialog gets call but I get null pointer exceptions on all my variables. The error still occurs even when I tell my activity to ignore screen orientation in the manifest. So I presume something has been left out of the example in the book do I need to override another method to save my variables in or something?

  • Please critisize this method

    - by Jakob
    Hi I've been looking around the net for some tab button close functionality, but all those solutions had some complicated eventhandler, and i wanted to try and keep it simple, but I might have broken good code ethics doing so, so please review this method and tell me what is wrong. public void AddCloseItem(string header, object content){ //Create tabitem with header and content StackPanel headerPanel = new StackPanel() { Orientation = Orientation.Horizontal, Height = 14}; headerPanel.Children.Add(new TextBlock() { Text = header }); Button closeBtn = new Button() { Content = new Image() { Source = new BitmapImage(new Uri("images/cross.png", UriKind.Relative)) }, Margin = new Thickness() { Left = 10 } }; headerPanel.Children.Add(closeBtn); TabItem newTabItem = new TabItem() { Header = headerPanel, Content = content }; //Add close button functionality closeBtn.Tag = newTabItem; closeBtn.Click += new RoutedEventHandler(closeBtn_Click); //Add item to list this.Add(newTabItem); } void closeBtn_Click(object sender, RoutedEventArgs e) { this.Remove((TabItem)((Button)sender).Tag); } So what I'm doing is storing the tabitem in the btn.Tag property, and then when the button is clicked i just remove the tabitem from my observablecollection, and the UI is updated appropriately. Am I using too much memory saving the tabitem to the Tag property?

  • Authentication Problem - not recognizing 'else' - Ruby on rails...

    - by bgadoci
    I can't seem to figure out what I am doing wrong here. I have implemented the Super Simple Authentication from Ryan Bates tutorial and while the login portion is functioning correctly, I can't get an error message and redirect to happen correctly for a bad login. Ryan Bates admits in his comments he left this out but can't seem to implement his recommendation. Basically what is happening is that when someone logs in correctly it works. When a bad password is entered it does the same redirect and flashes 'successfully logged in' thought they are not. The admin links do not show (which is correct and are the links protected by the <% if admin? %) but I need it to say 'failed login' and redirect to login path. Here is my code: SessionsController class SessionsController < ApplicationController def create if session[:password] = params[:password] flash[:notice] = 'Successfully logged in' redirect_to posts_path else flash[:notice] = "whoops" redirect_to login_path end end def destroy reset_session flash[:notice] = 'Successfully logged out' redirect_to posts_path end end ApplicationController class ApplicationController < ActionController::Base helper_method :admin? protected def authorize unless admin? flash[:error] = "unauthorized request" redirect_to posts_path false end end def admin? session[:password] == "123456" end helper :all # include all helpers, all the time protect_from_forgery # See ActionController::RequestForgeryProtection for details # end

  • Xcode - duplicate Target - new Target fails to build

    - by SirRatty
    Hi all, using Xcode 3.2.5 on 10.6.6 (10J521) I have an Xcode project containing 1 Target: "MyApp". It builds and runs successfully. As well as source and resource files, the Target contains a "Copy Files" build phase which copies "Sparkle.framework" in. The framework is in the same directory as the project. I want to duplicate this Target. Steps taken: Did "Clean all Targets". Right-clicked on the "MyApp" Target within Xcode, and then chose "Duplicate". Renamed the duplicated target to "MyAppTarget2". Selected "MyAppTarget2" as the Active Target from the popup menu in the top-left. Did "Build". The problem: error: Sparkle/Sparkle.h: No such file or directory This is puzzling! Each Build step appears to have been replicated in the duplicated Target, including the "Copy Files" phase. The Sparkle.framework exists at the path indicated by [Get Info on the Copy Phase item]. If I right-click on the Sparkle.framework file within the "Copy Files" build phase of the duplicated Target, and select "Reveal in Finder", then the correct Sparkle.framework file is shown. The required file exists at Sparkle.framework/Headers/Sparkle.h If I switch back to the original "MyApp" target, it builds and runs successfully. Am I doing something obviously wrong here? Thanks.

  • how to get the real bounds with google maps when fully zoomed out

    - by brad
    I have a map that shows location points based on the gbounds of the map. For example, any time the map is moved/zoomed, i find the bounds and query for locations that fall within those bounds. Unfortunately I'm unable to display all my locations when fully zoomed out. Reason being, gmaps reports the min/max long as whatever is at the edge of the map, but if you zoom out enough, you can get a longitudinal range that excludes visible locations. For instance, if you zoom your map so that you see NorthAmerica twice, on the far left and far right. The min/max long are around: -36.5625 to 170.15625. But this almost completely excludes NorthAmerica which lies in the -180 to -60 range. Obviously this is bothersome as you can actually see the continent NorthAmerica (twice), but when I query my for locations in the range from google maps, NorthAmerica isn't returned. My code for finding the min/max long is: bounds = gmap.getBounds(); min_lat = bounds.getSouthWest().lat() max_lat = bounds.getNorthEast().lat() Has anyone encountered this and can anyone suggest a workaround? Off the top of my head I can only thing of a hack: to check the zoom level and hardcode the min/max lats to -180/180 if necessary, which is definitely unacceptable.

  • keyup bindings not working in Firefox

    - by Jarred
    Hi. You can see my project here - http://www.inluxphoto.com/custom/jsgallery/index.php I am attempting to make the left and right arrow keys move the slideshow. I was able to get it to work in all browsers by following exactly the instructions on the front page of jqueryfordesigners.com (sorry I am only allowed one link). However, it is necessary that the keyup be unbinded until the animation completes, so the user cannot do a quick double tap of the key, which breaks the show. This led me to the following function - function keyCommands() { //Bind Keys according to keyAssignments function keyCommandBind() { $(document.documentElement).bind('keyup', keyAssignments) } //Bind functions to specific keys function keyAssignments() { if (event.keyCode == 37) { leftArrow(); } if (event.keyCode == 39) { rightArrow(); } if (event.keyCode == 32) { spaceBar(); } } function leftArrow() { //unbind, do stuff, rebind } function rightArrow() { //unbind, do stuff, rebind } function spaceBar() { //unbind, do stuff, rebind } keyCommandBind(); } This works in all browsers except Firefox & Camino. Firebug tells me event (ie event.keyCode) is not defined. That's true, it's not defined, and I understand that. However I don't understand why, if it's not defined, does it work in all other browsers. How can I appropriately define this? Or, am I doing it wrong? Any help would be most appreciated, thanks for your time!

  • Updates to fullcalendar events (through updateEvent) not maintaining across ajax month changes

    - by user549615
    Hey there. I have the calendar configured to allow me to edit and add (drag/drop) calendar events. I use .fullCalendar('updateEvent', theEvent) to edit an event, and it immediately updates on the page. Excellent. If I move to another month and then move back (get via ajax), that change is undone. By contrast, if I add a new event by drag/drop using: .fullCalendar('renderEvent', newEventObject, true); it appears on the calendar, and if I move to another month, and move back, it maintains. If I edit this newly added event object, and move to another month and back, the updates are retained! So the "stickiness" of edits seem to work on newly added events, but not events that were pulled via ajax (since it just pulls a fresh version via ajax when the month changes). My calendar config is: $('#calendar').fullCalendar({ theme: true, header: { left: "prev,next today", center: 'title', right: "today prev,next" }, selectable: true, selectHelper: true, select: calendarSelect, droppable: true, drop: calendarDrop, events:getCalendarData, eventClick:calendarEventClicked }); I tried setting editable: true, as well, but no dice. I noticed that if I view "event.source" on one of the ajax pulled events, it shows me a function, and if i read the source attribute on one of the "added" events, it reads [object]. So I tried setting the event.source of the event being added, to that same event object: curCalendarEvent.source = curCalendarEvent But no dice. It sets, but when I move back month forward again, it returns to the function as a source. I tried adding lazyFetching: false to my calendar config, but that didn't help. I even tried a .fullCalendar('renderEvent', curCalendarEvent, true); on the existing "edited" event to see if I could get "stick" to work, and it didn't help. The only thing I can think of doing is deleting the event flat out and recreating it. Any help would be appreciated. -Brian

  • Implementing Operator Overloading with Logarithms in C++

    - by Jacob Relkin
    Hello my friends, I'm having some issues with implementing a logarithm class with operator overloading in C++. My first goal is how I would implement the changeBase method, I've been having a tough time wrapping my head around it. My secoond goal is to be able to perform an operation where the left operand is a double and the right operand is a logarithm object. Here's a snippet of my log class: // coefficient: double // base: unsigned int // number: double class _log { double coefficient, number; unsigned int base; public: _log() { base = rand(); coefficient = rand(); number = rand(); } _log operator+ ( const double b ) const; _log operator* ( const double b ) const; _log operator- ( const double b ) const; _log operator/ ( const double b ) const; _log operator<< ( const _log &b ); double getValue() const; bool changeBase( unsigned int base ); }; You guys are awesome, thank you for your time.

  • Rendering LaTeX on third-party websites?

    - by A. Rex
    There are some sites on the web that render LaTeX into some more readable form, such as Wikipedia, some Wordpress blogs, and MathOverflow. They may use images, MathML, jsMath, or something like that. There are other sites on the web where LaTeX appears inline and is not rendered, such as the arXiv, various math forums, or my email. In fact, it is quite common to see an arXiv paper's abstract with raw LaTeX in it, e.g. this paper. Is there a plugin available for Firefox, or would it be possible to write one, that renders LaTeX within pages that do not provide a rendering mechanism themselves? (The LaTeX would be enclosed within dollar signs, e.g. $\pi$. See the arXiv link above.) Some notes: It may be impossible to render some of the code, because authors often copy-paste code directly from their source TeX files, which may contain things like "\cite{foo}" or undefined commands. These should be left alone. This question is a repost of a question from MathOverflow that was closed for not being related to math. There is one answer there, which is helpful, but perhaps Stack Overflow can provide better answers. I program a lot, but Javascript is not my specialty, so comments along the lines of "look at this library" are not particularly helpful to me (but may be to others).

  • Calculate total batch upload transfer percent with limited information

    - by GONeale
    Hi there, I have a system which uploads to a server file by file and displays a progress bar on file upload progress, then underneath a second progress bar which I want to indicate percentage of batch complete across all files queued to upload. Information and algorithms I can work out are: Bytes Sent / Total Bytes To Send = First progress bar (eg. 512KB of 1024KB (50%)) That works fine. However supposing I have two other files left to upload, but both file sizes are unknown (as this is only known once the file is about to commence upload, at which point it is compressed and file size is determined) how would I go about making my third progress bar? I didn't think this would be possible as I would need "Total Bytes Sent" / "Total Bytes To Send", to replicate the logic of my first progress bar on a larger scale, however I did get a version working: "Current file number we are on" / "total number of files to send" returning the percentage through the batch, however obviously will not incrementally update and it's pretty crude. So on further thinking I thought if I could incorporate the current file % with this algorithm I could perhaps get the correct progress percentage of my batch's current point. I tried this algorithm, but alas to no such avail (sorry to any math heads, it's probably quite apparent why it won't work) ("Current file number we are on" / "total number of files to send") * ("Bytes Sent" / "Total Bytes To Send") For example I thought I was on the right track when testing with this example: 2/3 (2nd of 3rd file) = 66% (this is right so far) but then when I added * 0.20 (for indicating only 20% of 2nd file has uploaded) we went back to 13%. What I need is only a little over 33%! I did try the inverse at 0.80 and a (2/3 * (2/3 * 0.2)) Can this be done without knowing entire bytes in batch to upload? Please help! Thank you!
