  • cleaning up pdftotext font issues

    - by mankoff
    I'm using pdftotext to make an ASCII version of a PDF document (made with LaTeX), because collaborators prefer a simple document in MS word. The plain text version I see looks good, but upon closer inspection the f character seems to be frequently mis-converted depending on what characters follow. For example, fi and fl often seem to become one special character, which I will try to paste here: ? and ?. What is the best way to clean up the output of pdftotext? I am thinking sed might be the right tool, but am not sure how to detect these special characters.

  • jQuery programming style?

    - by Sam Dufel
    I was recently asked to fix something on a site which I haven't worked on before. I haven't really worked with jQuery that much, but I figured I'd take a look and see if I could fix it. I've managed to mostly clear up the problem, but I'm still horrified at the way they chose to build this site. On document load, they replace the click() method of every anchor tag and form element with the same massive function. When clicked, that function then checks if the tag has one of a few different attributes (non-standard attributes, even), and does a variety of different tasks depending on what attributes exist and what their values are. Some hyperlinks have an attribute on them called 'ajaxrel', which makes the click() function look for another (hidden) hyperlink with an ID specified by the ajaxrel attribute, and then calls the click() function for that other hyperlink (which was also modified by this same click() function). On the server side, all the php files are quite long and have absolutely no indentation. This whole site has been a nightmare to debug. Is this standard jQuery practice? This navigation scheme seems terrible. Does anyone else actually use jQuery this way? I'd like to start incorporating it into my projects, but looking at this site is giving me a serious headache. Here's the click() function for hyperlinks: function ajaxBoxA(theElement, urltosend, ajaxbox, dialogbox) { if ($(theElement).attr("href") != undefined) var urltosend = $(theElement).attr("href"); if ($(theElement).attr('toajaxbox') != undefined) var ajaxbox = $(theElement).attr('toajaxbox'); // check to see if dialog box is called for. if ($(theElement).attr('dialogbox') != undefined) var dialogbox = $(theElement).attr('dialogbox'); var dodialog = 0; if (dialogbox != undefined) { // if dialogbox doesn't exist, then flag to create dialog box. var isDiaOpen = $('[ajaxbox="' + ajaxbox + '"]').parent().parent().is(".ui-dialog-container"); dodialog = 1; if (isDiaOpen) { dodialog = 0; } dialogbox = parseUri(dialogbox); dialogoptions = { close: function () { // $("[id^=hierarchy]",this).NestedSortableDestroy(); $(this).dialog('destroy').remove() } }; for ( var keyVar in dialogbox['queryKey'] ) eval( "dialogoptions." + keyVar + " = dialogbox['queryKey'][keyVar]"); }; $("body").append("<div id='TB_load'><img src='"+imgLoader.src+"' /></div>"); $('#TB_load').show(); if (urltosend.search(/\?/) > 0) { urltosend = urltosend + "&-ajax=1"; } else { urltosend = urltosend + "?-ajax=1"; } if ($('[ajaxbox="' + ajaxbox + '"]').length) { $('[ajaxbox="' + ajaxbox + '"]').each( function () { $(this).empty(); }); }; $.ajax({ type: "GET", url: urltosend, data: "", async: false, dataType: "html", success: function (html) { var re = /^<toajaxbox>(.*?)<\/toajaxbox>+(.*)/; if (re.test(html)) { var match = re.exec(html); ajaxbox = match[1]; html = Right(html, String(html).length - String(match[1]).length); } var re = /^<header>(.*?)<\/header>+(.*)/; if (re.test(html)) { var match = re.exec(html); window.location = match[1]; return false; } if (html.length > 0) { var newHtml = $(html); if ($('[ajaxbox="' + ajaxbox + '"]').length) { $('[ajaxbox="' + ajaxbox + '"]').each( function () { $(this).replaceWith(newHtml).ready( function () { ajaxBoxInit(newHtml) if (window.ajaxboxsuccess) ajaxboxsuccess(newHtml); }); }); if ($('[ajaxdialog="' + ajaxbox + '"]').length = 0) { if (dodialog) $(newHtml).wrap("<div class='flora ui-dialog-content' ajaxdialog='" + ajaxbox + "' style='overflow:auto;'></div>").parent().dialog(dialogoptions); } } else { $("body").append(newHtml).ready( function () { ajaxBoxInit(newHtml); if (window.ajaxboxsuccess) ajaxboxsuccess(newHtml); }); if (dodialog) $(newHtml).wrap("<div class='flora ui-dialog-content' ajaxdialog='" + ajaxbox + "' style='overflow:auto;'></div>").parent().dialog(dialogoptions); } } var rel = $(theElement).attr('ajaxtriggerrel'); if (rel != undefined) $('a[ajaxrel="' + rel + '"]').click(); tb_remove(); return false; }, complete: function () { $("#TB_load").remove(); } }); return false; }

  • ASP.NET MVC, JSON & non JavaScript clients

    - by redsquare
    I need to ensure that an application I am developing is accessable and also works with JavaScript turned off. I just need a pointer to assist with the following. I had 3 'chained' select boxes and I wanted JavaScript enabled clients to have a nice Ajax experience. I can easily write the required functionality to populate the chained boxes on the change event of the preceeding select using jQuery and JSON with a WCF service. However what about the non JavaScript client? Would I wrap a submit next to the select and place these inside their own form to post back with a certain action or different querstring parameter? Can the same controller give me a partial JSON response as well as feeding the full HTML response. Can anyone point me to a good demo that utilises both JSON and normal HTTP posts to produce the same result in ASP.NET MVC. All ASP.NET MVC demo/examples I see forget about the non JavaScript enabled client.

  • Unit testing custom controls in Silverlight

    - by Hrvoje
    I have several custom controls (some kind of frames for content and layout management, like wrap panel), and would like to write unit tests for them. It's hard to find any good examples except Silverlight control toolkit, which has some helper classes to do unit tests and it's quite complicated. For MVVM classes it's easy to write tests because they don't use SL dependency system and infrastructure. Questions: how to unit test DepedenyProperty, what do I need to test how to test attached property do I test bindings with theme or UserControl, like simple textblock content binding, or command/event binding in MVVM with UserControl what else do I test in my custom controls, beside my business logic any good tutorial to achieve tests like those in control toolkit How do I start? Is SL controls toolkit only option for learning? For testing framework i'm using one from control toolkit, and for continuus integration on TFS build server I planned to use Statlight (from codeplex). Any advice on that?

  • Is this an UITableView -beginUpdates documentation error?

    - by mystify
    I can't wrap my head around what they tried to say here in the docs for -beginUpdate: Call this method if you want subsequent insertions, deletion, and selection operations (for example, cellForRowAtIndexPath: and indexPathsForVisibleRows) to be animated simultaneously. Let's see... cellForRowAtIndexPath: and indexPathsForVisibleRows are both GETTER methods. They do not update anything and do not change anything. So why should I call -beginUpdates before calling these? And what's animated regarding these? Well, nothing, huh? Just want to make sure this is really an error in the docs and I didn't miss something.

  • MSDTC Distributed Transaction Coordinator Enabling

    - by Curtis White
    I've a web server and a separate SQL server. I'm trying to use transaction scope to ensure that SQL queries are completed with my linq queries. I wrap everything with this using (TransactionScope scope = new TransactionScope()) I want to know where I need to install DTC. Do I need to install it on the IIS 7.5 box AND the SQL server? Do I need to unblock some ports? Are there any security risk in doing so? I've setup this up once before but don't remember how. If I can't get access to DTC then is there any other way to ensure a lINQ and sql query is atomic?

  • Telugu (unicode) font rendering in emacs

    - by Prakash K
    I sometimes edit text in telugu language. However, when I open the file (UTF-8 encoded) in GNU emacs (version 23.1.50.1 on Ubuntu Jaunty) the text rendering is incorrect. The same text file opened in gedit is rendered correctly. Here's a snippet: ????????? ???? ???? ???????? rendred in gedit: And, the emacs rendering of the same text: Wherever glyphs need to be composited (not sure if it's the right word), emacs (or whatever library it uses) is not doing it right. Is there anyway to fix this? Perhaps tuning some setting in my configuration? Any ideas, please?

  • Dynamically changing background color of specific text without changing other attributes

    - by gsingh2011
    I've written a chrome extension to find text on a page based on a regex query. When text is matched, I wrap the matched text in a <span> tag that has the class highlight where highlight only changes the background color to yellow. The issue is that sometimes there are already styles applied to <span> tags in a webpage. For example, the webpage might have this defined: span { font-size: 200%; } So when I insert my <span> tag in another <span> tag, the font-size is actually 400%. Is there an easy way for my code to just change certain properties of the text, like the background color, without applying the webpage's styles twice?

  • [C++]Two windows fullscreen on two different screen.

    - by sirithang
    Hi! I'm actually working on an app to display an image onto a Dome. The dome projection system is constitued of two projector and a pc running a GentoO Linux and KDE, with nvidia TwinView system. Since here i've used SDL to display a fullscreen windows, and it display my app onto the two screen. But i just figured that i need to project two different images, one on each projector. That's why i search for a solution to display a fullscreen window on the first screen (projector) and another on the second. But SDL fullscreen just extend the window to the two screens. I can use any librairie (since it light and free, as i will wrap it into my small "API"), or change display setting. BTW it would be nice to have openGL support, since SDL manage only one window ^^"

  • How do I set sys.excepthook to invoke pdb globally in python?

    - by saffsd
    From Python docs: sys.excepthook(type, value, traceback)¶ This function prints out a given traceback and exception to sys.stderr. When an exception is raised and uncaught, the interpreter calls sys.excepthook with three arguments, the exception class, exception instance, and a traceback object. In an interactive session this happens just before control is returned to the prompt; in a Python program this happens just before the program exits. The handling of such top-level exceptions can be customized by assigning another three-argument function to sys.excepthook. http://docs.python.org/library/sys.html How do I modify this globally so the default action is to always invoke pdb? Is there a configuration file I can change? I don't want to wrap my code to do this.

  • correct way to store an exception in a variable

    - by Evan Teran
    I have an API which internally has some exceptions for error reporting. The basic structure is that it has a root exception object which inherits from std::exception, then it will throw some subclass of that. Since catching an exception thrown in one library and catching it in another can lead to undefined behavior (at least Qt complains about it and disallows it in many contexts). I would like to wrap the library calls in functions which will return a status code, and if an exception occurred, a copy of the exception object. What is the best way to store an exception (with it's polymorphic behavior) for later use? I believe that the c++0x futures API makes use of something like this. So what is the best approach? The best I can think of is to have a clone() method in each exception class which will return a pointer to an exception of the same type. But that's not very generic and doesn't deal with standard exceptions at all. Any thoughts?

  • Converting a C# DataTable instance to xml that contains HTML or binary data

    - by Wardy
    Hmmmm ... Although it works in most cases, one column has html data in it. It seems that doing this ... StringBuilder xmltarget = new StringBuilder(); XmlWriter xmlWriter = XmlWriter.Create(xmltarget); tableData.WriteXml(xmlWriter); ... doesn't identify where this html or binary data exists and wrap the data in cdata tags as it should ... Is there something i need to do to ensure the relevant checks are made and a working xml string is produced?

  • OpenAL device, buffer and context relationship

    - by Markus
    I'm trying to create an object oriented model to wrap OpenAL and have a little problem understanding the devices, buffers and contexts. From what I can see in the Programmer's Guide, there are multiple devices, each of which can have multiple contexts as well as multiple buffers. Each context has a listener, and the alListener*() functions all operate on the listener of the active context. (Meaning that I have to make another context active first if I wanted to change it's listener, if I got that right.) So far, so good. What irritates me though is that I need to pass a device to the alcCreateContext() function, but none to alGenBuffers(). How does this work then? When I open multiple devices, on which device are the buffers created? Are the buffers shared between all devices? What happens to the buffers if I close all open devices? (Or is there something I missed?)

  • What CSS should I use to create a series of horizontal, non-wrapping blocks?

    - by JOhnC
    I have a set of dynamically generated content - anywhere between 1 and about 25 blocks (each of which I want to be about 250px wide. Clearly, this can run off-screen, but that's fine since my design allows for horizontal scrolling (using jQuery - I don't want the browser to do it with its own scroll bars). So what CSS - cross-browser - is the best approach? Floats seem to wrap unreliably, and the dynamic nature of the content which changes frequently through ajax calls - means that recalculating the container width is not very practical. Other CSS-based option?

  • VB 2010 Express - Debugger is not breaking on errors, Sub producing error simply terminates

    - by hamlin11
    I'm using VB 2010 Express. When an error occurs in the form load function, the form load function simply terminates. Then, when I click on one of my buttons, the button click sub also terminates if it has an error. I can wrap the code that produces the errors in try/catch blocks, but I'd very much rather the debugger to throw an immediate break point (like usual) or at least exit the program. It's making it very difficult to program, not knowing whether or not previous Subs executed fully. Any thoughts on what might be going on? Thanks

  • swap a div to an embed form when user tweets using the @anywhere function box

    - by Jeff
    I'm using the @anywhere twitter function on the front page of my site (vocabbomb.com) and right now it works great to allow users to tweet straight away. Problem is, when they click tweet, it just reloads the twitter box, empty. I want it to load something new, like a "thank you, now fill in this email form" and show a mailchimp form. Ok so this is the @anywhere code currently working fine: <div id="tbox"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#tbox").tweetBox({ height: 100, width: 400, defaultContent: " #vocabbomb", label: "Use the word foo in a tweet:", }); }); </script> So this is fine, and when the user writes a tweet, it just re-displays the twitter box. I understand there is a function that lets you specify stuff after the tweet is made: (example from http://dev.twitter.com/pages/anywhere_tweetbox) <div id="example-ontweet"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#example-ontweet").tweetBox({ onTweet : function(plaintext, html) { console.log(plaintext); alert(html); } }); }); </script> Is this the best way to attempt this? Or do I need a function or something that changes what's in the div to something else? I want the mailchimp email form to show up after the tweet. It includes a ton of script and tags and starts like this: <!-- Begin MailChimp Signup Form --> <!--[if IE]> <style type="text/css" media="screen"> #mc_embed_signup fieldset {position: relative;} #mc_embed_signup legend {position: absolute; top: -1em; left: .2em;} </style> <![endif]--> <!--[if IE 7]> <style type="text/css" media="screen"> .mc-field-group {overflow:visible;} </style> <![endif]--> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script> <script type="text/javascript" src="http://downloads.mailchimp.com/js/jquery.validate.js"></script> <script type="text/javascript" src="http://downloads.mailchimp.com/js/jquery.form.js"></script> <div id="mc_embed_signup"> <form action="http://faresharenyc.us1.list-manage.com/subscribe/post?u=106b58b4751a007d826715754&amp;id=2fe6ba4e6a" method="post" id="mc-embedded-subscribe-form" name="mc-embedded-subscribe-form" class="validate" target="_blank" style="font: normal 100% Arial, sans-serif;font-size: 10px;"> ... So my attempt to just require it inside the function didn't work at all: <div id="tbox"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#tbox").tweetBox({ height: 100, width: 400, defaultContent: " #vocabbomb", label: "Use the word foo in a tweet:", onTweet: function(plain, html){ <?php require_once('mailchimp.html'); ?> } }); }); </script> Nettuts had a brief discussion here: http://net.tutsplus.com/tutorials/javascript-ajax/using-twitters-anywhere-service-in-6-steps/ I am seeing now that the 'onTweet' function simply adds some text above the twitter box, but doesn't actually replace the entire twitter box. How do I do that? Is it possible? Thanks!

  • Loading table sections when using headers

    - by Luis Tovar
    I cant seem to wrap my head around this. I have googled, and overstacked for hours now looking for examples that i can relate to. What I have is two arrays. The name of my first NSMutableArray is "showDates". I have 3 objects in here. Object 0: "Today, May 20th" Object 1: "Tomorrow, May 21st" Object 2: "Saturday, May 22nd" Then I have my second NSMutableArray named "showTimes" I have about 15 objects in there with strings in each object. ( i hope that makes sense? ) Each object is structured like this: Object 0: showID @"98022" eventID @"833" showTime @"1:30pm" showDate @"Today, May 20th" auditorium @"9" venue @"2991" Object 1: showID @"98222" eventID @"813" showTime @"2:30pm" showDate @"Tomorrow, May 21st" auditorium @"9" venue @"2991" Etc, etc, .... I have the headers working great in my tableView, but I cant seem to figure out how to add the objects in my "showTimes" array under the correct header. Any help would be greatly appreciated.

  • Strange CSS Positioning issue with a fader on a responsive site

    - by EPICWebDesign
    I'm developing a prototype responsive wordpress theme version of my homepage. I'm running into issues with the fader on the homepage. http://dev.epicwebdesign.ca/epicblog/ When the image switches, it uses position:absolute to overlay the pictures, then goes back to position:relative. I need to make the absolute be relative to the bottom left corner of the menu instead of the top left corner of #wrap so it doesn't overlap. I tried putting it in a container div like this: http://wiki.orbeon.com/forms/doc/contributor-guide/browser#TOC-Absolutely-positioned-box-inside-a-box-with-overflow:-auto-or-hidden but that doesn't seem to work. Any ideas? There are major CSS compatibility issues in IE, try it in chrome. It should look similar to http://epicwebdesign.ca. When the browser window is shrunk horizontially, the whole theme compensates.

  • Android - LinearLayout Horizontal with wrapping children

    - by kape123
    Is there a property to set for Android's LinearLayout that will enable it to properly wrap child controls? Meaning - I have changeable number of children and would like to lay out them horizontally like: Example: Control1, Control2, Control3, ... I do that by setting: ll.setOrientation(LinearLayout.HORIZONTAL); foreach (Child c in children) ll.addView(c); However, if I have large number of children, last one gets cuts off, instead of going to next line. Any idea how this can be fixed?

  • Implementation of APIs on diferent platforms

    - by b-gen-jack-o-neill
    OK, this is basicly just about any non-default OS API running on all different OS. But for my example let´s consider platform Windows, API SDL (Simple DirectMedia Layer). Actually this question came to my mind when I was reading about SDL. Originally, I thought that on Windows (and basicly any other OS) you must use OS API to make certain actions, like wrtiting to screen, creating window and so on, becouse that API knows what kernel calls and system subroutines calls it has to do. But when I read about SDL, I surprised me, becouse, you cannot make computer to do anything more than OS can, since you cannot acess HW directly, only thru OS API, from Console allocation to DirectX. So, my question actually is, how does this not-default-OS APIs work? Do they use (wrap) original system API (like MFC wraps win32 api)? Or, do they actually have direct acess to Windows kernel? Or is there any third, way in between? Thanks.

  • MVVM where does the code to load the data belong?

    - by cody
    As I wrap my head around the mvvm thing, the view is the view, and the viewmodel is 'a modal of a view' and the model are the entities we are dealing with (or at least that is my understanding). But I'm unclear as to what and when the model entities are populated. So for example: Lets say I have app that needs to create a new record in a DB. And that record should have default values to start with. Who is responsible for the new record, and getting the default values. Does this have anything to do with MVVM or is that part of a data access layer? Who calls the the viewmodel? Or for existing records when\where are the records retrieved? And saved if altered? Thanks

  • OO and Writing Drupal Modules

    - by Aaron
    Preface: Yes, I've read: http://drupal.org/node/547518 I am writing 'foo' module for Drupal6, where I am organizing the code in an OO fashion. There's a class called Foo that has a bunch of setters and accessors, and it is working quite well at abstracting some pretty nasty code and SQL. The question is is it common practice to expose a class for other modules, or is it better to wrap things in the more typical foo_myfnname()? For example, if I am writing the module's docs, should I tell people to do this: $foo = new Foo(); $something = $foo->get_something(); or tell them to call: foo_get_something(); which under the hood does: function foo_get_something() { $foo = new Foo(); return $foo->get_something(); }

  • Fadeout a tiled background image in load using JQuery

    - by user346602
    Hi, I've used JQuery in the past to fade divs in and out successfully. However, I have encountered a situation I can't quite wrap my head around: I am coding a site for a designer who has based the formatting of all the elements on a grid pattern he's created. As he wants the pattern elements to be the same size independent of the browser window, I think I can only do this via a repeating background tiled image in CSS. Now he wants the background pattern (only) to come in dark and fade to very light, while not effecting any of the other elements. Am I right in thinking it's impossible to call a tiled background pattern using a CSS selector? Does anyone have any suggestions of a workaround to this problem?

  • automated printouts from a wireless printer

    - by Piotr
    I have a wireless printer which is always on, and an always on fanless linux server. Looking at the mprinter project on Kickstarter I started to wonder if there is an app somewhere in the internet already that will allow to prepare an automated daily printout based on some settings. things to be printed could include - weather forecast for my locations, todo`s scheduled for that day, a "quote of a day" or "word of the day", stats from google analytics for my site, and many more ... I would set a printout at 6:15 every work day so its on my printer when I am already up, having a coffee. anyone knows something that can be used for such purpose? While I know this can be done by combining the power of TeX, cron and a script language to manage the dynamic part of the PDF I believe this is a use case someone has already addressed.
