  • Chrome extension custom cursor

    - by the_nakos
    Hi, I building an Google Chrome extension that place some IMG tag in sites. This img tag on :hover must show a custom cursor. The extension uses jQuery as its injected core script. I tried the following methods: 1. var cursor = 'url('+chrome.extension.getURL('icons/cursor.cur')+')'; $('#myImgId').css({ 'position': 'absolute', 'top':'5px', 'left':'5px', 'cursor':cursor }); This is the best working. On smaller sites its shows the cursor. On slower loading sites it does not. But on little sites it fails sometimes. 2. var cursor = 'url('+chrome.extension.getURL('icons/cursor.cur')+')'; $('<style>#myImgId{cursor:'+cursor+'}</style>').appendTo('head'); This did nothing at all. 3. In manifest.json I injected the css. "content_scripts": [ { "matches": ["http://*/*"], "css": ["css/style.css"], "js": ["j/c.js", "j/s.js"] } The css file just had the cursor:url(icons/cursor.cur) as I don't have idea, how to get real url in a css file. This isn't working at all. I think it must work like this, I didn't find reference for this on code.google though.

  • zend session exception on zend_session::start with forms

    - by Grant Collins
    Hi I'm having issues with trying to use Zend_Form_SubForm and sessions. My controller is in essance acting a wizard showing different subforms depending on the stage of the wizard. Using the example I am planning on storing the forms in a session namespace. My controller looks like this. include 'mylib/Form/addTaskWizardForm.php'; class AddtaskController extends Zend_Controller_Action{ private $config = null; private $log = null; private $subFormSession = null; /** * This function is called and initialises the global variables to this object * which is the configuration details and the logger to write to the log file. */ public function init(){ $this->config = Zend_Registry::getInstance()->get('config'); $this->log = Zend_Registry::getInstance()->get('log'); //set layout $this->_helper->layout->setLayout('no-sidemenus'); //we need to get the subforms and $wizardForms = new addTaskWizardForm(); $this->subFormSession = new Zend_Session_Namespace('addTaskWizardForms'); if(!isset($this->subFormSession->subforms)){ $this->subFormSession->subforms = $wizardForms; } } /** * The Landing page controller for the site. */ public function indexAction(){ $form = $this->subFormSession->subforms->getSubForm('start'); $this->view->form = $form; } However this is causing the application session to crash out with Uncaught exception 'Zend_Session_Exception' with message 'Zend_Session::start() Any idea why this is having issues with the Zend Session?? thanks.

  • Convert date to string upon saving a doctrine record

    - by takteek
    Hi, I'm trying to migrate one of my PHP projects to Doctrine. I've never used it before so there are a few things I don't understand. In my current code, I have a class similar to this: class ScheduleItem { private Date start; //A PEAR Date object. private Date end; public function getStart() { return $this-start; } public function setStart($val) { $this-start = $val; } public function getEnd() { return $this-end; } public function setEnd($val) { $this-end= $val; } } I have a ScheduleItemDAO class with methods like save(), getByID(), etc. When loading from and saving to the database, the DAO class converts the Date objects to and from strings so they can be stored in a timestamp field. In my attempt to move to Doctrine, I created a new class like this: class ScheduleItem extends Doctrine_Record { public function setTableDefinition() { $this-hasColumn('start', 'timestamp'); $this-hasColumn('end', 'timestamp'); } } I had hoped I would be able to use Date objects for the start and end times, and have them converted to strings when they are saved to the database. How can I accomplish this?

  • log4net - why would the same MyLog.Debug line not work at one point of startup, but work at another

    - by Greg
    Hi, During startup of my WinForms application I'm noting that there are a couple of points (before the MainForm renders) that do a "MyDataSet.GetInstance()". For the first one the MyLog.Debug line comes through in the VS2008 output window, but for a later one it does work and come through. What could explain this? What settings could I check at debug time to see why an output line for a MyLog.Debug line doesn't come out in the output window? namespace IntranetSync { public class MyDataSet { private static readonly ILog MyLog = LogManager.GetLogger(typeof(MyDataSet)); public static MyDataSet GetInstance() { MyLog.Debug("MyDataSet GetInstance() ====================================="); if (myDataSet == null) { myDataSet = new MyDataSet(); } return myDataSet; } . . . PS. What I have been doing re log4net repository initialization is putting the following line as a private variables in the classes I use logging - is this OK? static class Program { private static readonly ILog MyLog = LogManager.GetLogger(typeof(MainForm)); . . . public class Coordinator { private static readonly ILog MyLog = LogManager.GetLogger(typeof(MainForm)); . . . public class MyDataSet { private static readonly ILog MyLog = LogManager.GetLogger(typeof(MyDataSet)); . . .

  • JQuery set img src depending on where you click

    - by Anna
    Hello ! I used javascript for loading a picture on my website depending on which "small" photos in ul you clicked... I had something like that : <script type="text/javascript"> function viewImage(src, legende) { document.getElementById("imageBig").src = "images/photos/"+src; document.getElementById("legend").innerHTML = legende; } </script> and in html simply : things like that : <li><a href="#centre" onclick="javascript:viewImage('flute.jpg','La Reine de la Nuit au Comedia')"><img src="images/photos/carre-09.jpg" alt="" /></a> <a href="#centre" onclick="javascript:viewImage('perichole.jpg','Manuelita - <em>La P&eacute;richole</em> &agrave; l&#8217;Op&eacute;ra Comique')"><img src="images/photos/carre-03.jpg" alt="" /></a></li> <li><a href="#centre" onclick="javascript:viewImage('12.png','R&eacute;cital &agrave; Carnac, septembre 2008')"><img src="images/photos/carre-12.jpg" alt="Marion Baglan Carnac R&eacute;" /></a> <a href="#centre" onclick="javascript:viewImage('01.jpg','')"><img src="images/photos/carre-01.jpg" alt="" /></a></li> so you see, I could, depending on which small photos in the unordered list you clicked, load some particular photos, by passing the src string in argument... but I decided to use Jquery to get some fade-in effect. But I can't find a way to pass an argument that would tell my JQuery function which photo to load depending on where I clicked... stuck here : $(document).ready(function(){ $('#ulPhotos').click(function() { var newSrc= $('#imageBig').attr("src", "images/photos/11.jpg"); }); }); I don't want the 11.jpg to be hardcoded, I need to pass it through argument when I click on a special li element in my ul element of id #ulPhotos... I hope I'm clear enough sorry !

  • 'Fixed' for loop - what is more efficient?

    - by pimvdb
    I'm creating a tic-tac-toe game, and one of the functions has to iterate through each of the 9 fields (tic-tac-toe is played on a 3x3 grid). I was wondering what is more efficient (which one is perhaps faster, or what is the preferred way of scripting in such situation) - using two for nested loops like this: for(var i=0; i<3; i++) { for(var j=0; j<3; j++) { checkField(i, j); } } or hard-coding it like this: checkField(0, 0); checkField(0, 1); checkField(0, 2); checkField(1, 0); checkField(1, 1); checkField(1, 2); checkField(2, 0); checkField(2, 1); checkField(2, 2); As there are only 9 combinations, it would be perhaps overkill to use two nested for loops, but then again this is clearer to read. The for loop, however, will increment variables and check whether i and j are smaller than 3 every time as well. In this example, the time saving at least might be negligible, but what is the preferred way of coding in this case? Thanks.

  • Wrappers of primitive types in arraylist vs arrays

    - by ismail marmoush
    Hi, In "Core java 1" I've read CAUTION: An ArrayList is far less efficient than an int[] array because each value is separately wrapped inside an object. You would only want to use this construct for small collections when programmer convenience is more important than efficiency. But in my software I've already used Arraylist instead of normal arrays due to some requirements, though "The software is supposed to have high performance and after I've read the quoted text I started to panic!" one thing I can change is changing double variables to Double so as to prevent auto boxing and I don't know if that is worth it or not, in next sample algorithm public void multiply(final double val) { final int rows = getSize1(); final int cols = getSize2(); for (int i = 0; i < rows; i++) { for (int j = 0; j < cols; j++) { this.get(i).set(j, this.get(i).get(j) * val); } } } My question is does changing double to Double makes a difference ? or that's a micro optimizing that won't affect anything ? keep in mind I might be using large matrices.2nd Should I consider redesigning the whole program again ?

  • Counting entries in a list of dictionaries: for loop vs. list comprehension with map(itemgetter)

    - by Dennis Williamson
    In a Python program I'm writing I've compared using a for loop and increment variables versus list comprehension with map(itemgetter) and len() when counting entries in dictionaries which are in a list. It takes the same time using a each method. Am I doing something wrong or is there a better approach? Here is a greatly simplified and shortened data structure: list = [ {'key1': True, 'dontcare': False, 'ignoreme': False, 'key2': True, 'filenotfound': 'biscuits and gravy'}, {'key1': False, 'dontcare': False, 'ignoreme': False, 'key2': True, 'filenotfound': 'peaches and cream'}, {'key1': True, 'dontcare': False, 'ignoreme': False, 'key2': False, 'filenotfound': 'Abbott and Costello'}, {'key1': False, 'dontcare': False, 'ignoreme': True, 'key2': False, 'filenotfound': 'over and under'}, {'key1': True, 'dontcare': True, 'ignoreme': False, 'key2': True, 'filenotfound': 'Scotch and... well... neat, thanks'} ] Here is the for loop version: #!/usr/bin/env python # Python 2.6 # count the entries where key1 is True # keep a separate count for the subset that also have key2 True key1 = key2 = 0 for dictionary in list: if dictionary["key1"]: key1 += 1 if dictionary["key2"]: key2 += 1 print "Counts: key1: " + str(key1) + ", subset key2: " + str(key2) Output for the data above: Counts: key1: 3, subset key2: 2 Here is the other, perhaps more Pythonic, version: #!/usr/bin/env python # Python 2.6 # count the entries where key1 is True # keep a separate count for the subset that also have key2 True from operator import itemgetter KEY1 = 0 KEY2 = 1 getentries = itemgetter("key1", "key2") entries = map(getentries, list) key1 = len([x for x in entries if x[KEY1]]) key2 = len([x for x in entries if x[KEY1] and x[KEY2]]) print "Counts: key1: " + str(key1) + ", subset key2: " + str(key2) Output for the data above (same as before): Counts: key1: 3, subset key2: 2 I'm a tiny bit surprised these take the same amount of time. I wonder if there's something faster. I'm sure I'm overlooking something simple. One alternative I've considered is loading the data into a database and doing SQL queries, but the data doesn't need to persist and I'd have to profile the overhead of the data transfer, etc., and a database may not always be available. I have no control over the original form of the data. The code above is not going for style points.

  • A good solution for displaying galleries with lytebox and php

    - by Johann
    Hello I have thought for a while over an issue with the loading of images on a website-solution that I have programmed (For fun and the experience) The programming language used is PHP with MYSQL as the database language It also uses javascript, but not extensively I have recently realized that the engine I programmed, while it has it's smart solutions also carry a lot of flaws and redundant code. I have therefore decided to make a new one, now incorporating what I know, but didn't when I started the previous project. For the new system, there will be an option to add galleries to a site, and upload images to it. I have used the javascript image viewer Lytebox before. The screen goes dark and an image appears with a "Previous" and "next" button to view the other images. The problem is that I used groups with lytebox and the images themselves, resized as thumbs. This causes lytebox to work only when all the images have loaded. If you click a link before that, the image is shown as if you right click and choose "Show image" Information about these images is parsed from a database using a while statement with a counter that goes from 0 to sizeof() I'm thinking it probably isn't a good idea to have the images as the thumbs, even if you restrict the upload size. Likewise, adding thumbs at upload also seems like a hassle. It would be practical if the thumbs didn't show up before they were fully loaded. Has anyone got any good tips. Any help would be appreciated. Johann

  • How to Load external Div that has a dynamic content using ajax and jsp/servlets ?

    - by A.S al-shammari
    I need to use ajax feature to load external div element ( external jsp file) into the current page. That JSP page contains a dynamic content - e.g. content that is based on values received from the current session. I solved this problem , but I'm in doubt because I think that my solution is bad , or maybe there is better solution since I'm not expert. I have three files: Javascript function that is triggered when a element is clicked, it requests html data from a servlet: $("#inboxtable tbody tr").click(function(){ var trID = $(this).attr('id'); $.post("event?view=read",{id:trID}, function(data){ $("#eventContent").html(data); // load external file },"html"); // type }); The servlet "event" loads the data and generates HTML content using include method : String id = request.getParameter("id"); if (id != null) { v.add("Test"); v.add(id); session.setAttribute("readMessageVector", v); request.getRequestDispatcher("readMessage.jsp").include(request, response); } The readMessage jsp file looks like this: <p> Text: ${readMessageVector[0]} </p> <p> ID: ${readMessageVector[1]} </p> My questions Is this solution good enough to solve this problem - loading external jsp that has dynamic content ? Is there better solution ?

  • Background color remaining when switching views

    - by Guy
    Hi Guys. I have a UIViewController named equationVC who's user interface is being programmatically created from another NSObject class called equationCon. Upon loading equationVC, a method called chooseInterface is called from the equationCon class. I have a global variable (globalVar) that points to a user defined string. chooseInterface finds a method in the equationCon class that matches the string globalVar points to. In this case, let's say that globalVar points to a string that is called "methodThatMatches." In methodThatMatches, another view controller needs to show the results of what methodThatMatches did. methodThatMatches creates a new equationVC that calls upon methodThatMatches2. As a test, each method changes the color of the background. When the application starts up, I get a purple background, but as soon as I hit backwards I get another purple screen, which should be yellow. I do not think that I am release the view properly. Can anyone help? -(void)chooseInterface { NSString* equationTemp = [globalVar stringByReplacingOccurrencesOfString:@" " withString:@""]; equationTemp = [equationTemp stringByReplacingOccurrencesOfString:@"'" withString:@""]; SEL equationName = NSSelectorFromString(equationTemp); NSLog(@"selector! %@",NSStringFromSelector(equationName)); if([self respondsToSelector:equationName]){ [self performSelector:equationName]; } } -(void)methodThatMatches{ self.equationVC.view.backgroundColor = [UIColor yellowColor]; [setGlobalVar:@"methodThatMatches2"]; EquationVC* temp = [[EquationVC alloc] init]; [[self.equationVC navigationController] pushViewController:temp animated:YES ]; [temp release]; } -(void)methodThatmatches2{ self.equationVC.view.backgroundColor = [UIColor purpleColor]; }

  • How can I change the VisualState in a View from the ViewModel?

    - by Decker
    I'm new to WPF and MVVM. I think this is a simple question. My ViewModel is performing an asynch call to obtain data for a DataGrid which is bound to an ObservableCollection in the ViewModel. When the data is loaded, I set the proper ViewModel property and the DataGrid displays the data with no problem. However, I want to introduce a visual cue for the user that the data is loading. So, using Blend, I added this to my markup: <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="LoadingStateGroup"> <VisualState x:Name="HistoryLoading"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="HistoryGrid"> <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Hidden}"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="HistoryLoaded"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="WorkingStackPanel"> <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Hidden}"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> I think I know how to change the state in my code-behind (something similar to this): VisualStateManager.GoToElementState(LayoutRoot, "HistoryLoaded", true); However, the place where I want to do this is in the I/O completion method of my ViewModel which does not have a reference to it's corresponding View. How would I accomplish this using the MVVM pattern?

  • Optimizing a shared buffer in a producer/consumer multithreaded environment

    - by Etan
    I have some project where I have a single producer thread which writes events into a buffer, and an additional single consumer thread which takes events from the buffer. My goal is to optimize this thing for a single machine to achieve maximum throughput. Currently, I am using some simple lock-free ring buffer (lock-free is possible since I have only one consumer and one producer thread and therefore the pointers are only updated by a single thread). #define BUF_SIZE 32768 struct buf_t { volatile int writepos; volatile void * buffer[BUF_SIZE]; volatile int readpos;) }; void produce (buf_t *b, void * e) { int next = (b->writepos+1) % BUF_SIZE; while (b->readpos == next); // queue is full. wait b->buffer[b->writepos] = e; b->writepos = next; } void * consume (buf_t *b) { while (b->readpos == b->writepos); // nothing to consume. wait int next = (b->readpos+1) % BUF_SIZE; void * res = b->buffer[b->readpos]; b->readpos = next; return res; } buf_t *alloc () { buf_t *b = (buf_t *)malloc(sizeof(buf_t)); b->writepos = 0; b->readpos = 0; return b; } However, this implementation is not yet fast enough and should be optimized further. I've tried with different BUF_SIZE values and got some speed-up. Additionaly, I've moved writepos before the buffer and readpos after the buffer to ensure that both variables are on different cache lines which resulted also in some speed. What I need is a speedup of about 400 %. Do you have any ideas how I could achieve this using things like padding etc?

  • NASM - Load code from USB Drive

    - by new123456
    Hola, Would any assembly gurus know the argument (register dl) that signifies the first USB drive? I'm working through a couple of NASM tutorials, and would like to get a physical boot (I can get a clean one with qemu). This is the section of code that loads the "kernel" data from disk: loadkernel: mov si, LMSG ;; 'Loading kernel',13,10,0 call prints ;; ex puts() mov dl, 0x00 ;; The disk to load from mov ah, 0x02 ;; Read operation mov al, 0x01 ;; Sectors to read mov ch, 0x00 ;; Track mov cl, 0x02 ;; Sector mov dh, 0x00 ;; Head mov bx, 0x2000 ;; Buffer end mov es, bx mov bx, 0x0000 ;; Buffer start int 0x13 jc loadkernel mov ax, 0x2000 mov ds, ax jmp 0x2000:0x00 If it makes any difference, I'm running a stock Dell Inspiron 15 BIOS. Apparently, the correct value for me is 0x80. The BIOS loads the hard drives and labels them starting at 0x80 according to this answer. My particular BIOS decides to load the USB drive up as the first, for some reason, so I can boot from there.

  • How to debug problems in Linux kernel module `init()`?

    - by Kimvais
    I am using remote (k)gdb to debug a problem in a module that causes a panic when loaded e.g. when init() is called. The stack trace just shows that do_one_initcall(mod->init) causes the crash. In order to get the symbol file loaded in the gdb, I need to get the address of the module text section, and to get that I need to get the module loaded. Because the insmod in busybox (1.16.1) doesn't support -m so I'm stuck to grep modulename /proc/modules + adding the offset from nm to figure out the address. So I'm facing a sort a of a chicken and an egg problem here - to be able to debug the module loading, I need to get the module loaded - but in order to get the module loaded, I need to debug the problem... So I am currently thinking about two options - is there a way to get the address information either: by printk() in the module init code by printk() somewhere in the kernel code all this prior to calling the mod->init() - so I could place a breakpoint there, load the symbol file, hit c and see it crash and burn...

    I am having a problem with Paypal IPN response.

  • jQuery AJAX with two domains

    - by Andrew Burns
    OK here is the situation: I have an externally hosted CMS which works great for 99% of our needs. However on the more advanced things I inject my own CSS+JS and do magic. The problem I am running into is loading a simple HTML page from jQuery.ajax() calls. It appears to work in the sense that no warnings or errors are thrown; however in my success handler (which IS ran), the response is blank! I have been scratching my head for the whole morning trying to figure this out and the only thing I can think of is that is has something to do with the cross domain issue (even though it appears to work). Injected JavaScript: $(document).ready(function() { doui(); }); function doui() { $.ajax({ url: 'http://apps.natronacounty-wy.gov/css/feecalc/ui.htm', cache: false, success: ajax_createUI, charset: "utf-8", error: function(e) { alert(e); } }); } function ajax_createUI(data, textStatus) { alert(data); $("#ajax-content").html(data); } My ajax_createUI() success handler is called and textStatus is "success"; however data is empty. This JS file resides @ http://apps.natronacounty-wy.gov/css/js/feecalc.js however the CMS website (which gets the JS injected into it) resides @ http://www.natronacounty-wy.gov/ Am I just being stupid or is it a bug that it looks like it should be working but isn't?

  • Moving UIScrollView in App

    - by jsetting32
    Currently, I am attempting to create the same effect as Yahoo! Weather's App where the vital day information is at the bottom of the page on the top of a UIScrollView, that's contained by a UIView. I am having a hard time thinking about how this is going to happen or how I should implement this. If the user taps on the top of the UIScrollView which is located near the bottom of the laoded UIView, and starts to scroll up (/), the UIScrollView's frame should be moved to the TOP of the current UIView's frame. So the UIScrollView's y-value should change to UIView's (self.view.frame.origin.y) if the user starts scrolling UP on the UIScrollView which is located on the UIView's y-pixel ~280. Here's what the UIViewController should look like in the beginning of loading the ViewController... Then once the user slides his finger from the bottom to the top of the screen... this should happen........ And when the user scrolls to the top of the UIScrollView with all the content within it... the view should go back to the start picture shown... How is this done? I was thinking several UIGestureRecognizer's and Instantiating the UIscrollview at the lower part of the UIView... _weatherView = [[UIScrollView alloc] initWithFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y + 250, self.view.bounds.size.width, self.view.bounds.size.height - 44)]; _weatherView.contentSize = CGSizeMake(self.view.bounds.size.width, self.view.bounds.size.height * 4); _weatherView.backgroundColor = [UIColor clearColor]; [self.view addSubview:_weatherView]; The adding some UIGestureRecognizer delegate method.... But anyone have any ideas on the UIGestureRecognizer delegate method? And how it should be implemented? I can write the psuedo-code but I am having problems finding the delegate methods :P Thank you!!! ---- Break Time.... :)

  • Python: Access dictionary value inside of tuple and sort quickly by dict value

    - by Aquat33nfan
    I know that wasn't clear. Here's what I'm doing specifically. I have my list of dictionaries here: dict = [{int=0, value=A}, {int=1, value=B}, ... n] and I want to take them in combinations, so I used itertools and it gave me a tuple (Well, okay it gave me a memory object that I then used enumerate on so I could loop over it and enumerate gave ma tuple): for (index, tuple) in enumerate(combinations(dict, 2)): and this is where I have my problem. I want to identify which of the two items in the combination has the bigger 'int' value and which has the smaller value and assign them to variables (I'm actually using more than 2 in the combination so I can't just say if tuple[0]['int'] tuple[1]['int'] and do the assignment because I'd have to list this out a bunch of times and that's hard to manage). I was going to assign each 'int' value to a variable, sort it in a list, index the 'int' value in the list by 1, 2, 3, 4, 5 ... etc., then go back and access the dictionary I wanted by the int value and then assign the dictionary to a variable so I knew which was bigger. But I have a big list and lists and variable assignments are resource intensive and this is taking a long time (I had only a little bit of that written and it was taking forever to run). So I was hoping someone knew a fast way to do this. I actually could list out every possible combination of assignmnets using the if/thens but it's just like 5 pages of if/thens and assignments and is hard to read and manage when I want to change it. You've probably gathered this, but I"m new at programming. thx

  • JSLINT error: Move all 'var' declarations to the top of the function.

    - by Oleg Yaroshevych
    JSLINT site updated, and I cannot check JS scripts anymore. For me, this warning is not critical, and I don't want to go through thousands of lines to fix this, I want to find more critical problems. Does anybody know how to turn off this error, or use legacy JSLINT? UPDATE Example: function doSomethingWithNodes(nodes){ this.doSomething(); for (var i = 0; i < nodes.length; ++i){ this.doSomethingElse(nodes[i]); } doSomething(); // want to find this problem } jslint.com output: Error: Problem at line 4 character 8: Move all 'var' declarations to the top of the function. for (var i = 0; i < nodes.length; ++i){ Problem at line 4 character 8: Stopping, unable to continue. (44% scanned). Problem: Having variables on top of the functions is new requirement. I cannot use JSLINT to test code, because it stops scanning script on this error. I have a lot of code, and do not want to threat this warning as critical error.

  • Regex: match a non nested code block

    - by Sylvanas Garde
    I am currently writing a small texteditor. With this texteditor users are able to create small scripts for a very simple scripting engine. For a better overview I want to highlight codeblocks with the same command like GoTo(x,y) or Draw(x,y). To achieve this I want to use Regular Expresions (I am already using it to highlight other things like variables) Here is my Expression (I know it's very ugly): /(?<!GoTo|Draw|Example)(^(?:GoTo|Draw|Example)\(.+\)*?$)+(?!GoTo|Draw|Example)/gm It matches the following: lala GoTo(5656) -> MATCH 1 sdsd GoTo(sdsd) --comment -> MATCH 2 GoTo(23329); -> MATCH 3 Test() GoTo(12) -> MATCH 4 LALA Draw(23) -> MATCH 5 Draw(24) -> MATCH 6 Draw(25) -> MATCH 7 But what I want to achieve is, that the complete "blocks" of the same command are matched. In this case Match 2 & 4 and Match 5 & 6 & 7 should be one match. Tested with http://regex101.com/, the programming lanuage is vb.net. Any advise would be very useful, Thanks in advance!

  • How to get associated URLRequest from Event.COMPLETE fired by URLLoader

    - by matt lohkamp
    So let's say we want to load some XML - var xmlURL:String = 'content.xml'; var xmlURLRequest:URLRequest = new URLRequest(xmlURL); var xmlURLLoader:URLLoader = new URLLoader(xmlURLRequest); xmlURLLoader.addEventListener(Event.COMPLETE, function(e:Event):void{ trace('loaded',xmlURL); trace(XML(e.target.data)); }); If we need to know the source URL for that particular XML doc, we've got that variable to tell us, right? Now let's imagine that the xmlURL variable isn't around to help us - maybe we want to load 3 XML docs, named in sequence, and we want to use throwaway variables inside of a for-loop: for(var i:uint = 3; i > 0; i--){ var xmlURLLoader:URLLoader = new URLLoader(new URLRequest('content'+i+'.xml')); xmlURLLoader.addEventListener(Event.COMPLETE, function(e:Event):void{ trace(e.target.src); // I wish this worked... trace(XML(e.target.data)); }); } Suddenly it's not so easy, right? I hate that you can't just say e.target.src or whatever - is there a good way to associate URLLoaders with the URL they loaded data from? Am I missing something? It feels unintuitive to me.

  • Why would this Lua optimization hack help?

    - by Ian Boyd
    i'm looking over a document that describes various techniques to improve performance of Lua script code, and i'm shocked that such tricks would be required. (Although i'm quoting Lua, i've seen similar hacks in Javascript). Why would this optimization be required: For instance, the code for i = 1, 1000000 do local x = math.sin(i) end runs 30% slower than this one: local sin = math.sin for i = 1, 1000000 do local x = sin(i) end They're re-declaring sin function locally. Why would this be helpful? It's the job of the compiler to do that anyway. Why is the programmer having to do the compiler's job? i've seen similar things in Javascript; and so obviously there must be a very good reason why the interpreting compiler isn't doing its job. What is it? i see it repeatedly in the Lua environment i'm fiddling in; people redeclaring variables as local: local strfind = strfind local strlen = strlen local gsub = gsub local pairs = pairs local ipairs = ipairs local type = type local tinsert = tinsert local tremove = tremove local unpack = unpack local max = max local min = min local floor = floor local ceil = ceil local loadstring = loadstring local tostring = tostring local setmetatable = setmetatable local getmetatable = getmetatable local format = format local sin = math.sin What is going on here that people have to do the work of the compiler? Is the compiler confused by how to find format? Why is this an issue that a programmer has to deal with? Why would this not have been taken care of in 1993? i also seem to have hit a logical paradox: Optimizatin should not be done without profiling Lua has no ability to be profiled Lua should not be optimized

  • Is there a tool for managing redundant pages across a website?

    - by dmanexe
    I am in charge of constructing a website with a '2-dimensional' site map, as explained later. I am looking for (preferably a Wordpress plugin, as the site is built in Wordpress already) that would make managing thousands of pages a lot easier. To explain further, let me iterate my situation. I am building a website for a construction company, and they have several key cities and several key services. Now, they want a parent page for each service, and another unique page for the child sub-service, and finaly, a grandchild page for the city they are performing the service in. For example, if they were doing Concrete Construction in Los Angeles, the URL would look like: /concrete/construction/los-angeles The content on /los-angeles would be the same as on /malibu, or /burbank. However, there would be a different set of content for /concrete/design/los-angeles, but the entire page content (sans a few variables with city names) would be the same. Is there a way to manage or automate 'matrixing' this information on the site? I am looking for a tool that would allow me to easily add a 'city' with the same content across all grandchildren, per the child's content requirements. All of the grandchildren pages will have redundant content across them. Should something like this not exist, how difficult would it be to create, as a freelance side project? I need a tool like this, because I am approaching about ~500 cities and 50 services (Concrete Construction, Concrete Design, Concrete Engineering, etc)

  • Is it possible to redirect non-HTML files with HTTP? And chaining redirects?

    - by Earlz
    Hello, I have been thinking about a neat way of load balancing and one thing that would be required is to be capable of loading an image on an HTML page from multiple locations without rewriting the URL(on each load) So what I need to be able to do is have one URL which is the "static" URL. Such as http://example.com/myimage.png The image is not actually contained in example.com though. So example.com does a either a 302 or 301 or 307 HTTP response to cause a redirect to 2.example.com. How do browsers handle this with images like in this situation? Also, how do browsers handle multiple redirections for instance if 2.example.com also didn't contain it and it went to 3.example.com ? (Note, I am asking this because I've never seen a 301 redirect on anything but an HTML page) Also, which status code would be best to use. 301 means "moved permanently" which this "move" isn't permanent so I don't want it cached. Should I use 307? Is that supported by search engines and modern browsers?
