• Not able to override CSS within IFrame

  - by Madhur Ahuja

  I am using disqus comments for my jekyll blog with some CSS styles overriden in my stylesheet and used to work perfectly. Recently, disqus has introduced a new UI for their comments system which has completely broken the font colors. Since my site has dark background, I am trying to apply styles based on new disqus HTML structure generated. However, it seems that none of my styles get applied. It seems that is because disqus is loaded within iframe. Any ideas how can I fix the font colors. Example of the post: http://www.madhur.co.in/blog/2012/03/27/codeplexmovegit.html UPDATE Based on this question How to apply CSS to iFrame? it seems that you cannot style a child IFrame cross domain. I am wondering how it used to work earlier. Disqus even has documentation on it http://docs.disqus.com/help/69/

• How would I detect horizontal-black lines using ImageMagick?

  - by Zando

  So I have what is essentially a spreadsheet in TIFF format. There is some uniformity to it...for example, all the column widths are the same. I want to de-limit this sheet by those known-column widths and basically create lots of little graphic files, one for each cell, and run OCR on them and store it into a database. The problem is that the horizontal lines are not all the same height, so I need to use some kind of graphics library command to check if every pixel across is the same color (i.e. black). And if so, then I know I've reached the height-delimiter for a cell. How would I go about doing that? (I'm using RMagick)

• convert int to string for use in allegro function

  - by ace

  I am trying to run the following code using allegro. textout_ex(screen, font, numbComments , 100, 100, GREEN, BLACK); numbComments is an integer, the function prototype of this function is void textout_ex(BITMAP *bmp, const FONT *f, const char *s, int x, int y, int color, int bg); and i cannot, according to my understanding pass this integer in the third position. I therefore need to convert the integer into a string. I did it like this, but it didnt work. Help please? int score = numbComments; string Str; stringstream out; // YOU MUST INCLUDE <sstream> FOR THIS. out << score; Str = out.str(); and then tried to use the string Str, which didnt work

• Show javascript execution progress

  - by Midhat

  I have some javascript functions that take about 1 to 3 seconds. (some loops or mooML templating code.) During this time, the browser is just frozen. I tried showing a "loading" animation (gif image) before starting the operation and hiding it afterwords. but it just doesnt work. The browser freezes before it could render the image and hides it immediately when the function ends. Is there anything I can do to tell the browser to update the screen before going into javascript execution., Something like Application.DoEvents or background worker threads. So any comments/suggestions about how to show javascript execution progress. My primary target browser is IE6, but should also work on all latest browsers

• flex List Size not updating when itemRenderer resizes itself

  - by duder

  I've got a list with a custom itemRenderer that's just a rectangle of specific size. The list <s:List id="thelist" width="100%" dataProvider="{thelistdata}" itemRenderer="ListItem" borderVisible="true" /> Note the list's border is visible to help with debugging The itemRenderer <s:Rect id="box" width="50" height="50"> <s:fill> <s:SolidColor color="blue"/> </s:fill> </s:Rect> When the itemRenderer receives an event, it changes its size to half box.width = 25; box.height = 25; I see the itemRenderers are resizing themselves correctly, but the list itself stays the same size and the border stays where it is. Anyone knows how to fix this bug. Basically the list should refresh its size too to fit the smaller boxes.

• Providing SaaS functionality to a .NET portal with DLLs

  - by Abdullah Jibaly

  I'm not sure I'm asking the right question here, but I'm looking to provide web based functionality from one ASP.NET application to another remote 'portal-like' application. Is it possible to simply give the portal a DLL? As an example, let's say the SaaS web app has a patient-entry form that I want to be able to use from the portal application. I would like the portal app to be able to set preferences (permissions, color, style, etc), make a function call, and have that capability presented within a certain div or something. Is there any .NET technologies that provide this kind of integration?

• Problem drawing a polygon on data clusters in MATLAB

  - by Hossein

  Hi, I have some data points which I have devided into them into some clusters with some clustering algorithms as the picture below:(it might takes some time for the image to appear) Each color represents different cluster. I have to draw polygons around each cluster. I use convhull for this reason. But as you can see the polygon for the red cluster is very big and covers a lot of areas, which is not the one I am looking for. I need to draw lines(ploygons) exactly around my data sets. For example in the picture above I want a polygon that is drawn exactly the same(and around) as the red cluster with the 3 branches. In other words, in this case I need a polygon with 3 branches to cover my red clusters not that big polygon that covers the whole area. Can anyone help me with this? Please Note that the solution should be general, because the clusters will change in each run of the algorithm, so it needs to be in a way that is general.

  I want to change text color inside a rectangle periyodically Here is my trial: TrainIdBox::TrainIdBox() { boxRect = QRectF(0,0,40,15); testPen = QPen(Qt:red); i=0; startTimer(500); } QRectF TrainIdBox::boundingRect() const { return boxRect; } void TrainIdBox::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget) { Q_UNUSED(widget); Q_UNUSED(option); painter->setPen(QPen(drawingColor,2)); painter->drawRect(boxRect); painter->setPen(testPen); painter->drawText(boxRect,Qt::AlignCenter,"TEST"); } void TrainIdBox::timerEvent(QTimerEvent *te) { testPen = i % 2 == 0 ? QPen(Qt::green) : QPen(Qt::yellow); i++; update(boxRect); } This code does not working properly. What is wrong?

• Relative links in CSS, after moving Wordpress

  - by bozdoz

  I created a blog with Wordpress on a temporary test domain. I put it in the main directory, not a folder. Now I want to move it to the correct website, in a folder. I can update all of the MySQL values for the site URL, and the relative path links work just fine. The problem is that I can't seem to make my CSS path links work. I realize that my problem is that they are relative to the CSS file, in the WordPress theme, and not the page. But how can I fix this? Here is an example: #topNav {background:#3a93c3 url(wp-content/uploads/2011/07/blueNav.jpg) repeat-x;} I have tried adding './', '../', and '../../' to the beginning, but it doesn't work at all. Any suggestions?

• How would you start automating my job? - Part 2

  - by Jurily

  (Followup to this question) After surviving the first wave of incoming shipments (9 hours of copy/paste), I now believe I have all the requirements. Here is the updated workflow: Monkey collects email attachments (4 Excel spreadsheets, 1 PDF) Monkey creates central database, does complex calculations (right now this is also an Excel spreadsheet) Monkey sends data to two bosses, who set the retail prices independently; first one to reply wins Monkey sends order form to our other warehouses, also Excel Monkey sends spreadsheets to VIP customers, carefully sanitized and formatted (4 different discount categories) Jurily enters the data into the accounting system. I've given up on automating this part, there's too much business logic involved, and the database is a pile of sh^W legacy My question: What technologies would you use for a quick and dirty solution? I'm mostly sold on C#, but coming from a Linux/C++ background, I'm horribly confused about my choices in Microsoft-land. For bonus points: How would you redesign the whole system from the ground up? P.S. in case you were wondering, my job title is System Administrator.

• Odd visual issue with ListView item layout with two pressable pieces

  - by jnylen

  I wanted to make a ListView where the items have two pressable pieces, like the layouts that show up in a couple of places in the stock Android phone/contacts application: I have the layout working fine, including handling events from each piece separately, except for a visual issue when the smaller piece is pressed. In my application the smaller piece only gets a small ellipse for the background when it is pressed, like this: Note that is actually not my application - that is NubDial, but my application has the same problem. Since NubDial uses the exact same XML layout as the phone app, I'm not sure how relevant the list item layouts are, but here they are anyway: Contacts list: contacts_list_item.xml NubDial: contacts_list_item.xml Does anybody know what might be happening there?

• Using custom scrollbar on jquery lightbox

  - by Bhupi

  Hi, I need to use a custom scrollbar on jquery lightbox. My requirement is that when user clicks on a link then a popup appears and the popup contains 2 or 3 tabs, user can click on any tab to see it's content. In one of those tabs I need scrollbar to show huge content but the scrollbar should not be default it should be custom with any color. Currently I am using "JQuery's JScrollPane" plugin http://jscrollpane.kelvinluck.com to achieve the functionality, but this is not working on IE 6,7 and 8, mean scrollbar does not appear on IE. It works fine on Firefox and Chrome. Note: the same plugin works fine on IE also when I use it on page's element which is available while page load but not while the element is shown dynamically on lightbox. Thanks

• Common Lisp implementation with CFFI and thread support on Mac, Windows, and Linux?

  - by mcandre

  Goal: Install Hunchentoot and be able to run Hunchentoot as a background thread. This is what I do: Install Common Lisp. Install Quicklisp. (ql:quickload "hunchentoot") (hunchentoot:start (make-instance 'hunchentoot:acceptor :port 4242)) The last command is supposed to start Hunchentoot, then return to the interpreter for further Common Lisp forms. For CLISP, SBCL, ABCL, ECL, and CCL, I get one of two results: Hunchentoot's dependency Bordeaux Threads fails to install. hunchentoot:start hangs. The web page never loads, and never 404s.

• How to feed data over STDIN to multiple external commands in ruby.

  This question is a bit like my previous (answered) question: How to run multiple external commands in the background in ruby. But, in this case I am looking for a way to feed ruby strings over STDIN to external processes, something like this (the code below is not valid but illustrates my goal): #!/usr/bin/ruby str1 = 'In reality a relatively large string.....' str2 = 'Another large string' str3 = 'etc..' spawn 'some_command.sh', :stdin => str1 spawn 'some_command.sh', :stdin => str2 spawn 'some_command.sh', :stdin => str3 Process.waitall

• Best practice for error handling in an Android Service

  - by Omar Kohl

  I have an Android Service that does some background processing on an image using a separate Thread. If an error occurs in this Service or even worse in the thread, what is the best practice to inform the launching Activity of the problem and allow the application to recover to a stable state (i.e. the state it was in before launching the service). From within the Service I could post a Toast or a Notification, but that doesn't help me. I would like to inform the user about the problem but at the same time recover the application to a stable state.

• Overriding disabled input and textarea with CSS

  - by igluratds

  Hi, Im trying to override the grey text of a disabled input and textarea. At the moment Im only really concerned with it working in Webkit and Mozilla. At the moment Im currently using every trick in the book that I know of: input[@disabled=true], input[@disabled], button[disabled]:active, button[disabled], input[type="reset"][disabled]:active, input[type="reset"][disabled], input[type="button"][disabled]:active, input[type="button"][disabled], select[disabled] > input[type="button"], select[disabled] > input[type="button"]:active, input[type="submit"][disabled]:active, input[type="submit"][disabled],input[disabled="disabled"], input[disabled] { color: black !important; } Sure it does change the colour if I change it to something else, however when I choose black it is still greyed out a bit. Any ideas? I am using Ext JS if I can use that to manipulate it. Thanks.

• Algorithm for Source Control System?

  - by Michael Stum

  I need to write a simple source control system and wonder what algorithm I would use for file differences? I don't want to look into existing source code due to license concerns. I need to have it licensed under MPL so I can't look at any of the existing systems like CVS or Mercurial as they are all GPL licensed. Just to give some background, I just need some really simple functions - binary files in a folder. no subfolders and every file behaves like it's own repository. No Metadata except for some permissions. Overall really simple stuff, my single concern really is how to store only the differences of a file from revision to revision without wasting too much space but also without being too inefficient (Maybe store a full version every X changes, a bit like Keyframes in Videos?)

• How did Perl gain a reputation for being a write-only language?

  - by Andrew Grimm

  How did Perl gain a reputation (deserved, undeserved, or used to be deserved, no longer so) of being a "write only language"? Was it The syntax of the language Specific features that were available in the language Specific features not being available in the language (or at least old versions of it) The kind of tasks Perl was being used for The kind of people who use Perl (people who aren't full-time programmers) Criticism from people committed to another language Something else? Background: I'd like to know if some aspects that gave Perl the reputation of being write-only also apply to other languages (specifically ruby). Disclaimer: I recognise that Perl doesn't force people to do write-only code (can any language?), and that you can write bad code in any language.

• Why does bold monoface shift vertically on Windows?

  - by Aaron Digulla

  In Firefox 3.6, IE7 and Opera 10 on Windows, this HTML has an odd behavior: <html><head></head> <style> span { font-family: monospace; background-color: green; } span.b { font-weight: bold; } </style> <body> <span>Text</span><span class="b">Text</span><span>Text</span> </body> </html> The bold span in the middle is shifted down by one pixel. That doesn't happen for other fonts. Why is that? How can I fix it?

• Tinting iPhone application screen red

  - by btschumy

  I'm trying to place a red tint on all the screens of my iPhone application. I've experimented on a bitmap and found I get the effect I want by compositing a dark red color onto the screen image using Multiply (kCGBlendModeMultiply). So the question is how to efficiently do this in real time on the iPhone? One dumb way might be to grab a bitmap of the current screen, composite into the bitmap and then write the composited bitmap back to the screen. This seems like it would almost certainly be too slow. In addition, I need some way of knowing when part of the screen has been redrawn so I can update the tinting. I can almost get the effect I want by putting a red, translucent, fullscreen UIView above everything. That tints everything red within further intervention on my part, but the effect is much "muddier" than results from the composite. So do any wizards out there know of some mechanism I can use to automatically composite the red over the app in similar fashion to what the translucent red UIView does?

• One executable with cmd-line params or just many satellite executables?

  - by Nikos Baxevanis

  I design an application back-end. For now, it is a .NET process (a Console Application) which hosts various communication frameworks such as Agatha and NServiceBus. I need to periodically update my datastore with values (coming from the application while it's running). I found three possible ways: Accept command line arguments, so I can call my console app with -update. On start up a background thread will periodically invoke the update method. Create an updater.exe app which will do the updates, but I will have code duplication since in some way it will need to query the data from the source in order to save it to the datastore. Which one is better?

• Web-based JSON editor that works like property explorer with AJAXy input form

  - by dreftymac

  Background: This is a request for something that may not exist yet, but I've been meaning to build one for a long time. First I will ask if anyone has seen anything like it yet. Suppose you have an arbitrary JSON structure like the following: { 'str_title':'My Employee List' ,'str_lastmod': '2009-June-15' ,'arr_list':[ {'firstname':'john','lastname':'doe','age':'33',} ,{'firstname':'jane','lastname':'doe','age':'34',} ,{'firstname':'samuel','lastname':'doe','age':'35',} ] } Question: Is there a web-based JSON editor that could take a structure like this, and automatically allow the user to modify this in a user-friendly GUI? Example: Imagine an auto-generated HTML form that displays 2 input-type-text controls for both title and lastmod, and a table of input-type-text controls with three columns and three rows for arr_list ... with the ability to delete or add additional rows by clicking on a [+][X] next to each row in the table. Big Idea: The "big idea" behind this is that the user would be able to specify any arbitrary (non-recursive) JSON structure and then also be able to edit the structure with a GUI-based interaction (this would be similar to the "XML Editor Grid View" in XML Spy).
