• Javascript and CSS Popups

  - by user183315

  Hi all, I've got a question about CSS based popup windows, like those generated by jQuery UI's dialog system, or Colorbox. If I use those (or something like them) to open a popup window to an HTML page and that page has Javascript in it, does the Javascript in the popup window run in its own context, or does it become part of the context of the Javascript in the parent window that opened it? I ask so that I can write the Javascript on both pages (parent and popup) so there is no namespace collision. Thanks in advance! Doug

• Creating tooltips for each field in Sharepoint form.

  - by ephieste

  I want to create tool tips for each part in a form which employees have to fill in a share point web page. When users move the mouse cursor on each field (Title, description, department etc.) the related tip will be automatically became visible as a simple pop-up (tool tip) and summarize what they should write there. and when the mouse cursor is not on one of these fields there is no tool tip. How can I design such a system via share point designer? I am not able use any add ons. I can't upload any additional things to the server. I have to make page based design. I would be glad if you kindly help me.

• Does a multithreaded crawler in Python really speed things up?

  - by beagleguy

  Was looking to write a little web crawler in python. I was starting to investigate writing it as a multithreaded script, one pool of threads downloading and one pool processing results. Due to the GIL would it actually do simultaneous downloading? How does the GIL affect a web crawler? Would each thread pick some data off the socket, then move on to the next thread, let it pick some data off the socket, etc..? Basically I'm asking is doing a multi-threaded crawler in python really going to buy me much performance vs single threaded? thanks!

• qt/wxwidgets third party components?

  - by tkd

  I'm used to working in a Delphi and C# environment which seem to have a rich set of third party components available. I'm currently wanting to do cross-platform programming in C++ using either qt or wxwidgets. Is there a large market for third party components? I was looking at sourceforge and that doesn't seem to show much that is useful (how the hell do you find out what components or features are in a project without downloading the source?). I'm thinking carousel/coverflow components, rich datagrids (like the sort DevExpress provide). Or is this, write your own territory?

• Converting "is null" into a linq to sql statement

  - by Darryl Braaten

  I am having trouble replicating the following sql as a LINQ statement select TableA.* from TableA left outer join TableAinTableB on TableA.Id = TableAId where TableBId is null The following returns no lines from TableA in db.TableA join AinB in db.TableAinTableB on TableA.Id equals TableAId where AinB.TableBId == null select TableA Also tried and a few other things that didn't work. from TableA in db.TableA join AinB in db.TableAinTableB on TableA.Id equals TableAId where AinB == null select TableA TableAinTableB is a many to many table. The query I want will pull all the records from TableA that have no records in the middle table. My sql does what I want but I have no idea how to convert it to LINQ to SQL. I ended up working around it by just doing a db.ExecuteQuery("working sql"); But I would like to know if the query is possible in LINQ and how to write it, or a pointer to a document that covers this scenario. My searching did not uncover anything I found useful.

• idomatic batch processing of text in emacs?

  - by Stephen

  In python, you might do something like fout = open('out','w') fin = open('in') for line in fin: fout.write(process(line)+"\n") fin.close() fout.close() (I think it would be similar in many other languages as well). In emacs lisp, would you do something like (find-file 'out') (setq fout (current-buffer) (find-file 'in') (setq fin (current-buffer) (while moreLines (setq begin (point)) (move-end-of-line 1) (setq line (buffer-substring-no-properties begin (point)) ;; maybe (print (process line) fout) ;; or (save-excursion (set-buffer fout) (insert (process line))) (setq moreLines (= 0 (forward-line 1)))) (kill-buffer fin) (kill-buffer fout) which I got inspiration (and code) from here. Or should I try something entirely different? And how to remove the "" from the print statement? Thanks!

• macro returning length of arguments in C

  - by anon

  Is it possible to write a C macro that returns the length of its arguments? I want something that does: foo(1) -> 1 foo(cat, dog) -> 2 foo(red, green, blue) -> 3 Even better if this macro can be defined in such a way that it works with ## so that foo(1) -> bar1(1) foo(cat, dog) -> bar2(cat, dog) foo(red, green, blue) -> car3(red, green, blue) Thanks! EDIT: I really want a macro, not a function. Suggestions to use functions will be downvoted.

• 'Programming by Coincidence' Excercise: Java File Writer

  - by Tapas

  I just read the article Programming by Coincidence. At the end of the page there are excercises. A few code fragments that are cases of "programming by coincidence". But I cant figure out the error in this piece: This code comes from a general-purpose Java tracing suite. The function writes a string to a log file. It passes its unit test, but fails when one of the Web developers uses it. What coincidence does it rely on? public static void debug(String s) throws IOException { FileWriter fw = new FileWriter("debug.log", true); fw.write(s); fw.flush(); fw.close(); } What is wrong about this?

• PInvoke or using /clr:pure to compile

  - by Yin Zhu

  I have a set of numerical libraries in C++ and I want to call them interactively in a interpretive language like F# or IronPython. So I have two choices now: Compile the library in native DLL and use PInvoke to call functions in it. Compile the C++ library to .Net dll using visual c++ (/clr:pure compile option). The advantage of 1 is that it is very fast, however there are more work in it, e.g. I cannot PInvoke double pointer (e.g. float **), I must write another wrapper in the C++ library to make the interface friendly to .Net. The advantage of 2 is that I don't need to do know Mashaling strings, arrays, etc. However, the .net dll is slower compared to the native one. What others factors should be considered when choosing between the two?

• Firefox add-on tab-specific buttons and scripts, similar to Page Actions in Google Chrome

  - by Chetan

  I want to write a Firefox extension that acts exactly like the built-in RSS feed scanner (as an exercise). It should do the following: On each new page / tab load, it should scan the content of the page for RSS feeds If there are RSS feeds in the page, it should put a button in the location bar that the user can click On clicking the button, a speech bubble should appear under the button (the way a speech bubble appears under the bookmarks star when you click on it), with information on the feeds and buttons to subscribe to them So my main questions are: What is the process to run specific content scripts for specific pages? What is the process to use the results of those scripts to update the speech bubble for each location bar button for each tab? Basically, I'm trying to figure out how to do in Firefox what Page Actions are in Google Chrome. Please help! :)

  hello everybody, I have a WinServer 2008 machine with 8 local users on it. Basically I want to connect all of them remotely and simultaneously. I read that I should use Terminal server. I want to write a c# code (or use some code from the net) that configures the number of possible remotely and simultaneously connected local users to TS to be some N. Is it even possible? Is it limited from the first place to some value? connects the N local users simultaneously to the TS. Could someone please help me out? cheers to all,

• Detecting HTML5/CSS3 Features using Modernizr

  - by dwahlin

  HTML5, CSS3, and related technologies such as canvas and web sockets bring a lot of useful new features to the table that can take Web applications to the next level. These new technologies allow applications to be built using only HTML, CSS, and JavaScript allowing them to be viewed on a variety of form factors including tablets and phones. Although HTML5 features offer a lot of promise, it’s not realistic to develop applications using the latest technologies without worrying about supporting older browsers in the process. If history has taught us anything it’s that old browsers stick around for years and years which means developers have to deal with backward compatibility issues. This is especially true when deploying applications to the Internet that target the general public. This begs the question, “How do you move forward with HTML5 and CSS3 technologies while gracefully handling unsupported features in older browsers?” Although you can write code by hand to detect different HTML5 and CSS3 features, it’s not always straightforward. For example, to check for canvas support you need to write code similar to the following:   <script> window.onload = function () { if (canvasSupported()) { alert('canvas supported'); } }; function canvasSupported() { var canvas = document.createElement('canvas'); return (canvas.getContext && canvas.getContext('2d')); } </script> If you want to check for local storage support the following check can be made. It’s more involved than it should be due to a bug in older versions of Firefox. <script> window.onload = function () { if (localStorageSupported()) { alert('local storage supported'); } }; function localStorageSupported() { try { return ('localStorage' in window && window['localStorage'] != null); } catch(e) {} return false; } </script> Looking through the previous examples you can see that there’s more than meets the eye when it comes to checking browsers for HTML5 and CSS3 features. It takes a lot of work to test every possible scenario and every version of a given browser. Fortunately, you don’t have to resort to writing custom code to test what HTML5/CSS3 features a given browser supports. By using a script library called Modernizr you can add checks for different HTML5/CSS3 features into your pages with a minimal amount of code on your part. Let’s take a look at some of the key features Modernizr offers.   Getting Started with Modernizr The first time I heard the name “Modernizr” I thought it “modernized” older browsers by added missing functionality. In reality, Modernizr doesn’t actually handle adding missing features or “modernizing” older browsers. The Modernizr website states, “The name Modernizr actually stems from the goal of modernizing our development practices (and ourselves)”. Because it relies on feature detection rather than browser sniffing (a common technique used in the past – that never worked that great), Modernizr definitely provides a more modern way to test features that a browser supports and can even handle loading additional scripts called shims or polyfills that fill in holes that older browsers may have. It’s a great tool to have in your arsenal if you’re a web developer. Modernizr is available at http://modernizr.com. Two different types of scripts are available including a development script and custom production script. To generate a production script, the site provides a custom script generation tool rather than providing a single script that has everything under the sun for HTML5/CSS3 feature detection. Using the script generation tool you can pick the specific test functionality that you need and ignore everything that you don’t need. That way the script is kept as small as possible. An example of the custom script download screen is shown next. Notice that specific CSS3, HTML5, and related feature tests can be selected. Once you’ve downloaded your custom script you can add it into your web page using the standard <script> element and you’re ready to start using Modernizr. <script src="Scripts/Modernizr.js" type="text/javascript"></script>   Modernizr and the HTML Element Once you’ve add a script reference to Modernizr in a page it’ll go to work for you immediately. In fact, by adding the script several different CSS classes will be added to the page’s <html> element at runtime. These classes define what features the browser supports and what features it doesn’t support. Features that aren’t supported get a class name of “no-FeatureName”, for example “no-flexbox”. Features that are supported get a CSS class name based on the feature such as “canvas” or “websockets”. An example of classes added when running a page in Chrome is shown next:   <html class=" js flexbox canvas canvastext webgl no-touch geolocation postmessage websqldatabase indexeddb hashchange history draganddrop websockets rgba hsla multiplebgs backgroundsize borderimage borderradius boxshadow textshadow opacity cssanimations csscolumns cssgradients cssreflections csstransforms csstransforms3d csstransitions fontface generatedcontent video audio localstorage sessionstorage webworkers applicationcache svg inlinesvg smil svgclippaths"> Here’s an example of what the <html> element looks like at runtime with Internet Explorer 9:   <html class=" js no-flexbox canvas canvastext no-webgl no-touch geolocation postmessage no-websqldatabase no-indexeddb hashchange no-history draganddrop no-websockets rgba hsla multiplebgs backgroundsize no-borderimage borderradius boxshadow no-textshadow opacity no-cssanimations no-csscolumns no-cssgradients no-cssreflections csstransforms no-csstransforms3d no-csstransitions fontface generatedcontent video audio localstorage sessionstorage no-webworkers no-applicationcache svg inlinesvg smil svgclippaths">   When using Modernizr it’s a common practice to define an <html> element in your page with a no-js class added as shown next:   <html class="no-js">   You’ll see starter projects such as HTML5 Boilerplate (http://html5boilerplate.com) or Initializr (http://initializr.com) follow this approach (see my previous post for more information on HTML5 Boilerplate). By adding the no-js class it’s easy to tell if a browser has JavaScript enabled or not. If JavaScript is disabled then no-js will stay on the <html> element. If JavaScript is enabled, no-js will be removed by Modernizr and a js class will be added along with other classes that define supported/unsupported features. Working with HTML5 and CSS3 Features You can use the CSS classes added to the <html> element directly in your CSS files to determine what style properties to use based upon the features supported by a given browser. For example, the following CSS can be used to render a box shadow for browsers that support that feature and a simple border for browsers that don’t support the feature: .boxshadow #MyContainer { border: none; -webkit-box-shadow: #666 1px 1px 1px; -moz-box-shadow: #666 1px 1px 1px; } .no-boxshadow #MyContainer { border: 2px solid black; }   If a browser supports box-shadows the boxshadow CSS class will be added to the <html> element by Modernizr. It can then be associated with a given element. This example associates the boxshadow class with a div with an id of MyContainer. If the browser doesn’t support box shadows then the no-boxshadow class will be added to the <html> element and it can be used to render a standard border around the div. This provides a great way to leverage new CSS3 features in supported browsers while providing a graceful fallback for older browsers. In addition to using the CSS classes that Modernizr provides on the <html> element, you also use a global Modernizr object that’s created. This object exposes different properties that can be used to detect the availability of specific HTML5 or CSS3 features. For example, the following code can be used to detect canvas and local storage support. You can see that the code is much simpler than the code shown at the beginning of this post. It also has the added benefit of being tested by a large community of web developers around the world running a variety of browsers.   $(document).ready(function () { if (Modernizr.canvas) { //Add canvas code } if (Modernizr.localstorage) { //Add local storage code } }); The global Modernizr object can also be used to test for the presence of CSS3 features. The following code shows how to test support for border-radius and CSS transforms:   $(document).ready(function () { if (Modernizr.borderradius) { $('#MyDiv').addClass('borderRadiusStyle'); } if (Modernizr.csstransforms) { $('#MyDiv').addClass('transformsStyle'); } });   Several other CSS3 feature tests can be performed such as support for opacity, rgba, text-shadow, CSS animations, CSS transitions, multiple backgrounds, and more. A complete list of supported HTML5 and CSS3 tests that Modernizr supports can be found at http://www.modernizr.com/docs.   Loading Scripts using Modernizr In cases where a browser doesn’t support a specific feature you can either provide a graceful fallback or load a shim/polyfill script to fill in missing functionality where appropriate (more information about shims/polyfills can be found at https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills). Modernizr has a built-in script loader that can be used to test for a feature and then load a script if the feature isn’t available. The script loader is built-into Modernizr and is also available as a standalone yepnope script (http://yepnopejs.com). It’s extremely easy to get started using the script loader and it can really simplify the process of loading scripts based on the availability of a particular browser feature. To load scripts dynamically you can use Modernizr’s load() function which accepts properties defining the feature to test (test property), the script to load if the test succeeds (yep property), the script to load if the test fails (nope property), and a script to load regardless of if the test succeeds or fails (both property). An example of using load() with these properties is show next: Modernizr.load({ test: Modernizr.canvas, yep: 'html5CanvasAvailable.js’, nope: 'excanvas.js’, both: 'myCustomScript.js' }); In this example Modernizr is used to not only load scripts but also to test for the presence of the canvas feature. If the target browser supports the HTML5 canvas then the html5CanvasAvailable.js script will be loaded along with the myCustomScript.js script (use of the yep property in this example is a bit contrived – it was added simply to demonstrate how the property can be used in the load() function). Otherwise, a polyfill script named excanvas.js will be loaded to add missing canvas functionality for Internet Explorer versions prior to 9. Once excanvas.js is loaded the myCustomScript.js script will be loaded. Because Modernizr handles loading scripts, you can also use it in creative ways. For example, you can use it to load local scripts when a 3rd party Content Delivery Network (CDN) such as one provided by Google or Microsoft is unavailable for whatever reason. The Modernizr documentation provides the following example that demonstrates the process for providing a local fallback for jQuery when a CDN is down:   Modernizr.load([ { load: '//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.js', complete: function () { if (!window.jQuery) { Modernizr.load('js/libs/jquery-1.6.4.min.js'); } } }, { // This will wait for the fallback to load and // execute if it needs to. load: 'needs-jQuery.js' } ]); This code attempts to load jQuery from the Google CDN first. Once the script is downloaded (or if it fails) the function associated with complete will be called. The function checks to make sure that the jQuery object is available and if it’s not Modernizr is used to load a local jQuery script. After all of that occurs a script named needs-jQuery.js will be loaded. Conclusion If you’re building applications that use some of the latest and greatest features available in HTML5 and CSS3 then Modernizr is an essential tool. By using it you can reduce the amount of custom code required to test for browser features and provide graceful fallbacks or even load shim/polyfill scripts for older browsers to help fill in missing functionality.

• Creating an AST node in Erlang

  - by dagda1

  Hi, I am playing about with Erlang and I am trying to write a simple arithmetic parser. I want to try and parse the following expression: ((12+3)-4) I want to parse the expression into a stack of AST nodes. When parsing this expression, I would first of all create a binary expression for the (12+3) expression which would look something like this in C#: var binaryStructure = new BinaryStructure(); binaryStructure.Left = IntegerLiteralExpression(12); binaryStructure.Right = IntegerLiteralExpression(4); binaryStructure.Operator = binaryExpression.Operator != BinaryOperatorType.Addition; I am quite new to Erlang and I am wondering how I would go about creating a structure like this in Erlang that I can place on a List that I would use as the stack of expressions. Can anyone suggest how to create such a tree like structure? Would a function be a good fit? Thanks Paul

• Calling a protected Windows executable with Perl

  - by Jake

  I'm trying to write a perl script that determines which users are currently logged into Windows by using query.exe (c:\Windows\system32\query.exe). Perl is unable to access this file, unable to execute it, even unable to see that it exists, as I've found with the following code: print `dir c:\\windows\\system32\\query*`; This produces the following output: 07/13/2009 05:16 PM 1,363,456 Query.dll 1 File(s) 1,363,456 bytes 0 Dir(s) 183,987,658,752 bytes free I've checked the user executing the script using perl's getlogin function, and it returns the name of a member of the local Administrators group (specifically, me). I've also tried adding read/execute permissions for "Everyone", but windows keeps giving me access denied errors when I try to modify this file's permissions. Finally, I've tried running perl.exe as an administrator but that doesn't fix the problem either. Is this something I can solve by changing some settings in Windows? Do I need to add something to my perl script? Or is there just no way to grant perl access to some of these processes?

• How to rollback a database deployment without losing new data?

  - by devlife

  My company uses virtual machines for our web/app servers. This allows for very easy rollbacks of a deployment if something goes wrong. However, if an app server deployment also requires a database deployment and we have to rollback I'm kind of at a loss. How can you rollback database schema changes without losing data? The only thing that I can think of is to write a script that will drop/revert tables/columns back to their original state. Is this really the best way?

• PHP application variable... maybe?

  - by James

  I went to a PHP job interview, I was asked to implement a piece of code to detect visitors are bots to crawl thru the website and steal content. So I implemented a few lines of code to detect if the site is being refreshed/visited too quickly/often by using a session variable to store last visit timestamp. I got told that session varaibles can be manupilated by cookies etc, so I am wondering if there is a application variable that I can use to store the timestamp information against visitor IPs eg $_SERVER[REMOTE_ADDR]? I know that I can write the data to a file but it's not very good for a high traffic website. Regards James

• Blackberry Player, custom data source

  - by Alex

  Hello I must create a custom media player within the application with support for mp3 and wav files. I read in the documentation i cant seek or get the media file duration without a custom datasoruce. I checked the demo in the JDE 4.6 but i have still problems... I cant get the duration, it return much more then the expected so i`m sure i screwed up something while i modified the code to read the mp3 file locally from the filesystem. Somebody can help me what i did wrong ? (I can hear the mp3, so the player plays it correctly from start to end) I must support OSs = 4.6.

• Drupal auto change user role in module

  - by Marques

  I am trying to write a module that will change a user's permissions once a node form is inserted into the database. I already have a role assigned when a user registers, but i want that role to be changed once they create a 'company' profile in this case which is when they fill out a cck form of 'company_post' type. My code is below... switch ($op) { case 'insert': if ($node->type == 'company_post') { } ? im not sure what to put in the if statement because I don't really know how to reference the users roles or how to change them. ? So my question is what code can I use to change the users current role to a new role? (Both roles are already created in drupal and have seperate permissions)

• Coding in Other (Spoken) Languages

  - by contagious

  Something i've always wondered, and I can't find any mention of it anywhere online. When a shop from, say Japan, writes code, would I be able to read it in english? Or do languages, like C, php, anything, have Japanese translations that they write? I guess what i'm asking is does every single coder in the world know enough english to use the exact same reserved words I do? Would this code: If (i < size){ switch case 1: print "hi there" default: print "no, thank you" } else { print "yes, thank you" } display the exact same as I'm seeing it right now in english, or would some other non-english-speaking person see the words "if", "switch", "case", "default", "print", and "else" in their native language? EDIT - yes, this is serious. I didn't know if different localiztions of a language have different keywords. or if there are even different localizations at all.
