  • Keeping the number of objects and event-listeners on stage as low as possible

    - by DevEight
    Hello. I am creating a site with lots of big scrollable text-boxes in it. Each text-box object contained some text, and two buttons to scroll up/down with. The scroll buttons each had an event listener so the text moved when you clicked them. These text-boxes were stacked on-top of each other with all except one having an alpha of 0. If I wanted to change which text-box is active I move it to the front and call a small TweenLite animation. To the left (outside of the text-box objects) I have an object similar to a menu. It also has about 12 or so event-listeners (one for every button). This turns out cause A LOT of lag an it's very troublesome for my laptop to run it. What I need help with doing is to reduce the number of event-listeners on the stage and also the amount of text-boxes. What I was thinking was to add the text-boxes using AS so I only have 1 on the stage at a time but I couldn't figure out how to do it. I also thought it might be better to just use 1 big event-listeners and from mouseX and mouseY decide which button the user is trying to push. Are there any better alternatives to this? And if so, please elaborate on how to do it.

  • Codeigniter - Active record - sql - complex join

    - by Jack
    I have a function that retrieves all tags from a table: function global_popular_tags() { $this->db->select('tags.*, COUNT(tags.id) AS count'); $this->db->from('tags'); $this->db->join('tags_to_work', 'tags.id = tags_to_work.tag_id'); $this->db->group_by('tags.id'); $this->db->order_by('count', 'desc'); $query = $this->db->get()->result_array(); return $query; } I have another table called 'work'. The 'work' table has a 'draft' column with values of either 1 or 0. I want the COUNT(tags.id) to take into account whether the work with the specific tag is in draft mode (1) or not. Say there are 10 pieces of work tagged with, for example, 'design'. The COUNT will be 10. But 2 of these pieces of work are in draft mode, so the COUNT should really be 8. How do I manage this?

  • Complex data ordering...

    - by Povylas
    Hi, I have one tables ids in an array and they are ordered in the way I want and I have to select data from another table using those ids and in a order they are listen in the array. Pretty confusing but I was thinking of two solutions giving ORDER BY parameter the array but I do not know if that possible and another is to get all the necessary data and then turn it to array (mysql_fetch_assoc) then compare those two and somehow order the new array using the ids array. But I also do not know how to do this... Any ideas?

  • [perl] Efficient processing of large text

    - by jesper
    I have text file that contains over one million urls. I have to process this file in order to assign urls to groups, based on host address: { 'http://www.ex1.com' = ['http://www.ex1.com/...', 'http://www.ex1.com/...', ...], 'http://www.ex2.com' = ['http://www.ex2.com/...', 'http://www.ex2.com/...', ...] } My current basic solution takes about 600mb of RAM to do this (size of file is about 300mb). Could You provide some more efficient ways? My current solution simply reads line by line, extracts host address by regex and put url into hash.

  • Rails botches the SQL on a complex save

    - by Dan B
    Hi, I am doing something seemingly pretty easy, but Rails is messing up the SQL. I could just execute my own SQL, but the framework should be able to handle this. Here is the save I am trying to perform: w = WhipSenVote.find(:first, :conditions => ["whip_bill_id = ? AND whip_sen_id = ?", bill_id, k]) w.votes_no = w.votes_no - 1 w.save My generated SQL looks like this: SELECT * FROM "whip_sen_votes" WHERE (whip_bill_id = E'1' AND whip_sen_id = 7) LIMIT 1 And then: UPDATE "whip_sen_votes" SET "votes_yes" = 14, "updated_at" = '2009-11-13 19:55:54.807000' WHERE "id" = 15 The first select statement is correct, but as you can see, the Update SQL statement is pretty wrong, though the votes_yes value is correct. Any ideas? Thanks!

  • Dynamic form in PHP not processing correctly

    - by user1497265
    My last question regarding this suggested I incorporate AJAX with PHP. However, I really wanted to try PHP exclusively for this project, and I seem to have made it about 95% there. I just need help on this one issue. Here's a quick background. My project requires a dynamic form to be populated with a max limit of 10 questions. Each form contains one question, one question number, and a text field. Students would go on and answer the questions. This is all driven by a database table (obviously), and when a question gets answered correctly, it will close and the next question in line will appear. There will always be 10 questions on the page. Here's how the coding looks, and it works perfectly. <? $rt = mysql_query("SELECT * FROM The_Questions WHERE Status='Open' ORDER BY 'Number' LIMIT 10"); while ($row = mysql_fetch_array($rt)) { $number=$row[0]; $category = $row[1]; $question=$row[2]; $points=$row[4]; $_SESSION['number'] = $number; ?> <form action="processor.php" method="post" class="qForm"> <div class="questionCell"> <div class="question"><? echo $number; echo $question ?></div> <div class="answer">Answer: <input class="inputField" name="q1" type="text" size="40" maxlength="40" /> <input name="HHQuestion" value="Submit" type="submit" /></div> </div> </form> <? } ?> The questions appear as they should, in the correct order, and the correct limit. Everything seems to be looking fine until a question gets answered and gets processed through the processor.php action. First here's the code to the processor.php file: <?php session_start(); if(isset($_POST["HHQuestion"])){ $dbhost = 'localhost'; $dbname = 'localhost'; $dbuser = 'localhost'; $dbpass = 'localhost'; $conn = mysql_connect($dbhost, $dbuser, $dbpass); mysql_select_db($dbname, $conn); { $number1 = $_SESSION['number']; $answer=$_POST['q1']; $sql="SELECT * FROM The_Questions WHERE Number='$number1'"; $result=mysql_query($sql); $row=mysql_fetch_array($result); $question = $row[2]; echo $question .'<br>'; echo $number1.'<br>'; echo $answer; } } ?> This is NOT live yet, and for testing purposes I'm echoing the question, question number, and answer (as you can see). What's happening is that the $question and $number1 displays the last question in the array (the $answer displays correctly, meaning it displays whatever was written in the dynamic form). Can anyone tell me why that is? If I change the LIMIT number to 20, the processor.php action will display the 20th question and number, even if I was answering question 8, for example, in the dynamic form. Again, the dynamic forms are being displayed correctly, and are numbered correctly. For some unknown reason to me, the action - processor.php - is grabbing the last question in the array. Any ideas on what I'm doing wrong? I'm hoping it's a simple code change that I'm overlooking. Thanks in advance guys!

  • How to properly manage a complex DB structure?

    - by errr
    Let's say you have several systems using the same DB - each uses several schemes (sometimes same as the other). This structure of these schemes is somewhat very big and complicated. Now, how could you possibly manage such scheme structure? Obviously using some sort of "configuration" - the simplest would be SQL scripts, but a more reasonable solution would be XMLs which can be easily converted into SQL, or some other readable solution (for example, JPA's XMLs or Annotations). This solution though, causes a problem where you can't really tell if your configuration matches the structure of the DB schemes exactly. You can't say if those two are synchronized. Why wouldn't they? Well, in such big structure there are going to be many changes, and you won't always remember to save/commit your configuration after you've altered the schemes, or maybe you did save/commit it, but eventually didn't altered anything in the schemes and forgot to undo the changes to the configuration. More than that, another problem (not caused by the configuration, but isn't addressed by it either) is versioning. I don't see any good way of managing the DB schemes versions (say our last alteration makes 3 systems crash - not good, how to "rollback"?). And thoughts? thx.

  • Handle complex options with Boost's program_options

    - by R S
    I have a program that generates graphs using different multi-level models. Each multi-level model consists of a generation of a smaller seed graph (say, 50 nodes) which can be created from several models (for example - for each possible edge, choose to include it with probability p). After the seed graph generation, the graph is expanded into a larger one (say 1000 nodes), using one of another set of models. In each of the two stages, each model require a different number of parameters. I would like to be have program_options parse the different possible parameters, according to the names of the models. For example, say I have two seed graphs models: SA, which has 1 parameters, and SB, which has two. Also for the expansion part, I have two models: A and B, again with 1 and 2 parameters, respectively. I would like to be able do something like: ./graph_generator --seed=SA 0.1 --expansion=A 0.2 ./graph_generator --seed=SB 0.1 3 --expansion=A 0.2 ./graph_generator --seed=SA 0.1 --expansion=B 10 20 ./graph_generator --seed=SB 0.1 3 --expansion=B 10 20 and have the parameters parsed correctly. Is that even possible?

  • Processing data from an AJAX request

    - by Josh K
    I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } }); If I leave off the eval(data) then everything works fine. Well, except for data still being undefined in success. Note that I'm taking an array of objects in PHP and then passing them out through json_encode. Would that make any difference? There has been no progress made on this. I'm willing to throw more code up if someone believes they can help. Here is the PHP side of things private function _get_user_colors($id) { $u = new User(); $u->get_where(array('id' => $id)); $bar = array(); $bar['user'] = $u->stored; foreach($user->colors as $color) { $bar['colors'][] = $color; } echo(json_encode($bar)); } I have had zero issues using this with other PHP based scripts. I don't know why Javascript would take issue with it.

  • AngularJS - Processing $http response in service

    - by bsreekanth
    I recently posted a detailed description of the issue I am facing here at SO. As I couldn't send an actual $http request, I used timeout to simulate asynchronous behavior. Data binding from my model to view is working correct, with the help of @Gloppy Now, when I use $http instead of $timeout (tested locally), I could see the asynchronous request was successful and data is filled with json response in my service. But, my view is not updating. updated Plunkr here

  • Modal forms get in the way of processing

    - by Botax
    I’m working on an interface in VB6 to interact with a sound editor to automate certain tasks mainly using the editor’s object handles and activating them through SendMessage/PostMessage. In general it works OK, except that the editor has some dialog boxes that open in modal mode and freeze everything on the interface, including the timers. Is there a practical way to get these dialog boxes to open modeless or to interact with them from the interface after they pop up? I tried an MDI form, but it also freezes along with everything else. The only way to override the modal mode of these boxes is to launch an independent applet beforehand to address the dialog boxes with a timer, but the process is somewhat cumbersome. All I need to do with the dialog boxes is click the OK button or hit the return key.

  • Function to get a string and return same after processing in C

    - by C0de_Hard
    I am working on a code which requires a function. This function gets a string as input and returns a string. What I have planned so far is to get a str[], remove all $'s and spaces, and store this in another string which is returned later: char *getstring(char str[]) { int i=0; char rtn[255]; while (i<strlen(str)) { if (str[i] != " " || str[i] != "$" ) rtn[i] = str[i]; else rtn[i] = ''; } return str; } I dont feel like this will work. Any ideas?? :-S

  • Automatically Persisting a Complex Java Object

    - by VeeArr
    For a project I am working on, I need to persist a number of POJOs to a database. The POJOs class definitions are sometimes highly nested, but they should flatten okay, as the nesting is tree-like and contains no cycles (and the base elements are eventually primitives/Strings). It is preferred that the solution used create one table per data type and that the tables will have one field per primitive member in the POJO. Subclassing and similar problems are not issues for this particular project. Does anybody know of any existing solutions that can: Automatically generate a CREATE TABLE definition from the class definition Automatically generate a query to persist an object to the database, given an instance of the object Automatically generate a query to retrieve an object from the database and return it as a POJO, given a key. Solutions that can do this with minimum modifications/annotions to the class files and minimum external configuration are preferred. Example: Java classes //Class to be persisted class TypeA { String guid; long timestamp; TypeB data1; TypeC data2; } class TypeB { int id; int someData; } class TypeC { int id; int otherData; } Could map to CREATE TABLE TypeA ( guid CHAR(255), timestamp BIGINT, data1_id INT, data1_someData INT, data2_id INt, data2_otherData INT ); Or something similar.
