  • KineticJS issue with repeatable mouse event

    - by nuclearpeace
    I have noob issue here (i obviously missing something). I simplified it from my bigger application: When i click blue rectangle, i add another layer to the stage that includes red rectangle (clickable), when i clik this red rectangle it removes second layer with red rect. Problem: When i click blue rect second time, nothing happens :( i.e. app works only once, and i need to add/remove second layer(with red rect) repeatedly. What's wrong? :) You can see it here, Fiddle http://jsfiddle.net/mAX8r/ Code: <!DOCTYPE HTML> <html> <head> <style> body { margin: 0px; padding: 0px; } canvas { border: 1px solid #9C9898; } </style> <script src="http://www.html5canvastutorials.com/libraries/kinetic-v4.0.3.js"> </script> <script> window.onload = function() { var stage = new Kinetic.Stage({ container: 'container', width: 578, height: 200 }); var layerBlue = new Kinetic.Layer(); var layerRed = new Kinetic.Layer(); var rectBlue = new Kinetic.Rect({ x: 100, y: 75, width: 100, height: 50, fill: 'blue', stroke: 'black', strokeWidth: 4 }); var rectRed = new Kinetic.Rect({ x: 300, y: 75, width: 100, height: 50, fill: 'red', stroke: 'black', strokeWidth: 4 }); // mouse events rectBlue.on('click', function() { stage.add(layerRed); stage.draw(); }); rectRed.on('click', function() { layerRed.remove(); stage.draw(); }); // add the shape to the layer layerBlue.add(rectBlue); layerRed.add(rectRed); // add the layer to the stage stage.add(layerBlue); }; </script> </head> <body> <div id="container"></div> </body> </html>

  • Need help in sorting the programming buzz-words

    - by cwap
    How do you sort out the good buzz from the bad buzz? - I really need your help here :) I see a lot of buzz-words nowadays, both here on SO and in school. For example, we had a teacher who everyone respected, who said "be careful about gold-plating and death-by-interfacing". Now, everyone and their mama cries whenever I'm creating an interface.. Another example would be here on SO where lately "premature optimization is the root of all evil", so everytime someone asks a perfomance question, he'll get that sentence thrown in his face. A few months ago I remember it was all about NHibernate in here, etc., etc... These things comes and goes, but only the good buzz stays. Now, how do you seperate the good from the bad? By reading blogs from respected persons? By trying to come to a conclusion on your own, and then try to convince others that you're right? By simply ignoring it?

  • Hide and Show content based on Cookie value

    - by danit
    Here is my Jquery: $("#tool").click(function() { $(".chelp").slideToggle(); $("wrapper").animate({ opacity: 1.0 },200).slideToggle(200, function() { $("#tool img").toggle(); }); }); When you click #tool img #wrapper is hidden along with .chelp. I need to control this with a cookie, so when the user hides #wrapper it remains hidden on all pages or when they re-visit the page. I know there is a jQuery Cookie plugin, but I'd like to do this with plain Javascript rather then including another plugin. Can anyone tell me how i can build in it in plain javascript and merge with the JQuery to create a cookie, then check the cookie each time the page loads to see if #wrapper should be hidden or displayed?

  • Defining Views Based On Selection

    - by Wayne
    Well the title isn't very descriptive but I'm not exactly sure how to explain but here goes! I have a web application (can use either MVC or standard web forms) which a user signs in to. If the user has signed up for more than one product they will have the option to switch between them. For the sakes of this example lets say User1 signs in and has access to Product1, Product2 and Product3. Now, each product will be very different and offer different functionally. What I want is the main view to be focused around the product they have selected and not redirected to a sub domain. What I don't want to have to do is get them to go to www.mysite.com/product1 or www.mysite.com/product2 but simply www.mysite.com regardless of the product they have selected and have the site render the views etc for that product. Wow does any of that make any sense? I was thinking mabe the use of sessions or something and URL rewriting? Are there any sample apps out there that make use of the same kind of functionallity that I could take a look at? Thanks for any help I appreciate it!

  • Win32 C++ Import path based on OS?

    - by Zenox
    I'm working with some legacy code that has an import like so: #import "C:\Program Files\Common Files\System\ado\msado15.dll" rename("EOF", "EndOfFile") The problem is, on a x64 machine the path for this import is in the 'Program Files (x86)' directory. Is there a preprocessor macro I can wrap around this to make it work on either? Edit: I think I found it. _M_X64, but im not 100% sure if this is correct.

  • How to filter items in a ListBox based on a searched string

    - by tiz
    Hi all, I have a Windows Forms application (C#) containing a ListBox into which I have added some items (I'm not using a DataSource). I want to filter the items in the ListBox to show only items containing a string I'm searching for. I have done this by keeping a list of the original items and selecting matching items from that list each time the search string changes and updating the ListBox.Items Is there a more elegant/efficient way to do this?

  • MVC2 AJAX - determining UpdateTargetId based on the returned data

    - by DanielJW
    The scenario: I'm creating a login form for an MVC2 application. How i'm doing it: The form submits to an MVC2 action which validates the username/password. If it fails validation the action returns the form (a partial view) for the user to try again. If it passes validation the action returns the page the user was visiting before they logged in (a view). What i want to happen: 1 - when the form is submitted and the user validates successfully, The returned result should replace the current page (like what happens if you don't set an UpdateTargetId). 2 - When the form is submitted and the user fails validation, the returned result should replace the form (like what happens if you set the UpdateTargetID to the form's containing element). The problem: I can make both of those things work, but not at the same time. I can either have it always replace the current page, or always just replace the contents of the UpdateTargetId element. But I need it to be able to do either depending on whether the user successfully validated or not. What I need The ideal solution would be to be able to examine the result of the ajax request and determine whether to use the UpdateTargetId (replacing just the form) or not (replacing the whole page). I expect it would involve some work with jquery (assuming it's possible) but i'm not really that great with jquery yet to figure out how to do it myself. If it can't be done this way I'm also open to other methods/solutions for making it work in a similar fashion. Thanks in advance ..

  • Different sizes of same strings - Telnet programming

    - by tommyogp
    Hi all, I have been trying to create an iphone app sending telnet command. However what puzzling me is that the sizes of certain strings are so much different, particularly when they include \n or \r. I listed out a few examples. Please assist. const char *a = "play 25\n"; int sizeBitA1 = sizeof(a); // 8 units int sizeBitA2 = sizeof("play 25\n"); // 9 units const char *b = "\r\n"; int sizeBitB1 = sizeof(b); // 8 units int sizeBitB2 = sizeof("\r\n"); // 3 units

  • R programming function without ()

    - by Mark Kennedy
    So, I Have the following very simple map.r file. I'm trying to have the user type "click" in interactive mode and then have the function . Since it's a function, the user has to type "click()" how can I make it so that they only have to the word (w/o parentheses), and then have that function do something with the img. So the user types: mydist("image.pnm") click //And then the function click does what it's supposed to mydist <- function(mapfile) { img <- read.pnm(mapfile) plot(img) } click <- function() { //Prompt user to click on img }

  • Legalities of programming companion Android apps

    - by honeal
    I'm interested in creating companion apps to several current Android apps and was curious if there is a legal issue with using their name and/or icons from the app. Like the companion app being called Angry Birds Companion or something and you were to use a picture of the level or one of the characters, etc (I'm simply pulling from thin air so don't judge the idea, just the question, please). I know there are Strategy guides to video games that use icons and names, but I'm assuming they have prior consent. Does anyone have any factual input on this?

  • Output custom messages based on row value

    - by decimal
    I've made a simple guestbook mysql/php page. An entry is displayed if the approve column has a value of 1. For the adminstrator, I want to display either "message approved" or "not approved". Here's my code: while ($row = mysql_fetch_array ($r)) { print "<p>Guest:" .$row['name']. "</p> <p>Date:" .$row['date']. "</p> <p>Comment:". $row['comment']. "</p>"; if ($row['approve'] = '1') { print '<p>YES, the message has been approved</p>'; } else { print '<p>NO, it hasn\'t been approved</p>'; } Whatever value the if statement checks approve is equal to, all approve values are output as that value.

  • Expanding a row in a div-based table

    - by magneticMonster
    I have a stack of <div> elements that show a name. I'd like to include a + link off to the side that, when clicked, expands the <div> and adds more detailed information (from a RoR controller). After poking around on the net, I found link_to_remote and related RoR stuff, but I can't seem to get the right combination to work together. Can someone point me to a tutorial or show what the controller and view interaction should look like? Thanks!

  • JQuery Mobile bind event to listview

    - by nycynik
    I am trying to add a vclick to a dynamic JQM listview. But I can not figure out how to identify which number is being clicked. http://jsfiddle.net/2hR9w/ for (var x=0; x<2; x++ ) { $("#listitem"+x).bind("vclick",function(e) { console.log("clicked"+x); }); console.log(x); } ? Something is wrong with the code, but i can't figure out why x is always the max loop value, since I feel like it should be set at the time of the loop. it always reads clicked2, never clicked1.

  • programming/selling mobile apps internationally

    - by dootcher
    If I'm looking to sell my app in other markets other than the U.S. on both Android and iOS, do I need to do anything inside the app coding-wise? I don't imagine that I need to but I just want to make sure. Also, while I'm at it, how do I collect on international app purchases considering they are in another currency? Will the currency be automatically converted to U.S. dollars or is that my job? Any insight on either of these questions would be greatly appreciated.

  • where to place browser event (resize/scroll) detection call

    - by karl
    I'm trying to alert a message when the browser is resized or scrolled. I'm detecting the 2 events in the body <body onResize="doDisp();" onScroll="doDisp();" > where doDisp is this inside the <script> tag <script type="text/javascript"> function doDisp(){ alert("browser changing state"); } </script> but isn't it bad practice to have javascript in the body tag? Is there a cross-browser way to keep all the javascript inside the <script> tags?

  • compare two characters based on subset

    - by schultem
    I have a simple dataframe with two columns: df <- data.frame(x = c(1,1,2,2,3), y = c(rep(1:2,2),1), target = c('a','a','a','b','a')) I would like to compare the strings in the target column (find out whether they are equal or not, i.e., TRUE or FALSE) within every level of x (same number for x). First I would like to compare lines 1 and 2, then 3 and 4 ... My problem is that I am missing some comparisons, for example, line 5 has only one case instead of two - so it should turn out to be FALSE. Variable y indicates the first and second case within x. I played around with ddply doing something like: ddply(df, .(x), summarise, ifelse(as.character(df[df$y == '1',]$target), as.character(df[df$y == '2',]$target),0,1)) which is ugly ... and does not work ... Any insights how I could achieve this comparison? Thanks

  • Access php multidimensional array key based on a variable string

    - by ggirtsou
    I have stored the XML path to items in a string like this: response->items->item. What I need to do is to access an array called $xml_array like this: $xml_array['response']['items']['item'] When I write it in the code it works. The thing is that I want it to be done on the fly. I use this to convert response->items->item to ['response']['items']['item']: $xml_path = 'response->items->item'; $explode_path = explode('->', $xml_path); $correct_string = false; foreach($explode_path as $path) { $correct_string .= '[\''.$path.'\']'; } the problem is that I can't access $xml_array by doing this: $xml_array[$correct_string] So I end up with this: $xml_tag = 'title'; $xml_path = 'response->items->item'; $correct_string = '$items = $xml2array'; $explode_path = explode('->', $xml_path); foreach($explode_path as $path) { $correct_string .= '[\''.$path.'\']'; } $correct_string .= ';'; eval($correct_string); foreach($items as $item) { echo $item[$xml_tag].'<br />'; } and access the $xml_array array through $items array. Is there any way I can do this and avoid using eval()? Thanks in advance!

  • Seek a jQuery-based inplace HTML editor

    - by justSteve
    I just stepped over to http://plugins.jquery.com/search/node/editor - lots and lots of choices - and if to judge by the dates, many new offerings. I'm hoping someone can help me narrow down the field according to these priorities... Stability & Well-formed XHTML (might argue against some of the most recent unless they are revisions with a clear track-record) Inplace editing Good AJAX integration For internal / admin / CMS usage so it can be as bloated as it needs to be long as it's easy to implement the basics: bold ital indents lists No need for tables but dropdowns that show relevent CSS selectors would be nice. thnkx

  • serving cached files based upon cookie?

    - by matthewsteiner
    So I realized something today. In my application, you really can't get anywhere (except the front page) unless you're logged in. And you can't be logged in without a cookie. So my front page could be cached, except the problem is if you are logged in (have a cookie set) then it should just redirect into the application. Is there a way for nginx to look for a cookie and if it finds it then deliver a cached file? Just an idea...
