  • Caching the struct Object

    - by PRamod
    How do I create a cache for a struct pointer object in Objective-C? Is there any third party component for caching objects as Java and .NET have? I have the following struct: typedef struct _news { references char *headline; char *story_url; } news; I have a double pointer for the above struct in an interface class. I would like to cache it for some time using Objective-C.

  • Dynamically adding values to a form with JQuery/Javascript

    - by bigstylee
    I am creating a private message system to allow users to communicate between one another within the context of the website (ie, not emails). I have created this function to handle all my form submissions. I would like to achieve a solution without modifying this function (ideally). $("form.reload").submit(function(){ alert($(this).serialize()); /* Debugging */ $.post($(this).attr("action"), $(this).serialize() ,function(data){ if(data){ $("#error").html(data); }else{ location.reload(); }; }); return false; }); Within my form I am using JQuery Autocomplete to find usernames. This function works perfectly. My first solution was to add buttons within the form with the necessary values. select: function(event, ui) { $("#message_to").append("<input type=\"button\" class=\"recipient\" name=\"recipients[]\" value=\"" + ui.item.label + "\" onclick=\"$(this).remove()\" />"); } <form method="post" action="/messages-create"> <div id="message_to"></div> </div> For some reason the values of recipients are not getting posted. My second solution was to add to a post array that already existed in the form select: function(event, ui) { $(input[name=recipeients[]).val = ui.item.label; /* Need to add to array, not replace! */ $("#message_to").append("<input type=\"button\" class=\"recipient\" name=\"recipient\" value=\"" + ui.item.label + "\" onclick=\"$(this).remove(); /* Remove from recipients */\" />"); } <form method="post" action="/messages-create" class="reload"> <input type="hidden" name="recipients[]" value="" /> <div id="message_to"></div> </div> This works ok, but I have been unable to work out how to append to the recipients[] array only replace with the new label. Moving on from this, I also need to know how to then remove this value from the array. Thanks in advance!

  • PulpCore music playback - loop sound and animate volume

    - by Peter Perhác
    I have been experimenting with PulpCore, trying to create my own tower defence game (not-playable yet), and I am enjoying it very much I ran into a problem that I can't quite figure out. I extended PulpCore with the JOrbis thing to allow OGG files to be played. Works fine. However, pulpCore seems to have a problem with looping the sound WHILE animating the volume level. I tried this with wav file too, to make sure it isn't jOrbis that breaks it. The code is like this: Sound bgMusic = Sound.load("music/music.ogg"); Playback musicPlayback; ... musicVolume = new Fixed(0.75); musicPlayback = bgMusic.loop(musicVolume); //TODO figure out why it's NOT looping when volume is animated // musicVolume.animate(0, musicVolume.get(), FADE_IN_TIME); This code, for as long as the last line is commented out, plays the music.ogg again and again in an endless loop (which I can stop by calling stop on the Playback object returned from loop(). However, I would like the music to fade in smoothly, so following the advice of the PulpCore API docs, I added the last line which will create the fade-in but the music will only play once and then stop. I wonder why is that? Here is a bit of the documentation: Playback pulpcore.sound.Sound.loop(Fixed level) Loops this sound clip with the specified volume level (0.0 to 1.0). The level may have a property animation attached. Parameters: level Returns: a Playback object for this unique sound playback (one Sound can have many simultaneous Playback objects) or null if the sound could not be played. So what could be the problem? I repeat, with the last line, the sound fades in but doesn't loop, without it it loops but starts with the specified 0.75 volume level. Why can't I animate the volume of the looped music playback? What am I doing wrong? Anyone has any experience with pulpCore and has come across this problem? Anyone could please download PulpCore and try to loop music which fades-in (out)? note: I need to keep a reference to the Playback object returned so I can kill music later.

  • Amusing or Sad? Network Solutions

    - by dbasnett
    When I got sick my email ended up in every drug sellers email list. Some days I get over 200 emails selling everything from Viagra to Xanax. Either they don't know what my condition is or they are telling me you are a goner, might as well chill-ax and have a good time. In order to cut down on the mail being downloaded I thought I would add all of the Junk email senders from Outlook to my Network Solution mail server. Much to my amazement I could not find that import Spammers button, so I submitted a tech support request. Here is the response: Thank you for contacting Network Solutions Customer Service Department. We are committed to creating the best Customer experience possible. One of the first ways we can demonstrate our commitment to this goal is to quickly and efficiently handle your recent request. We apologize for any inconvenience this might have caused you. With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers. An alternative option is for you to create a Custom Filter that filters unwanted e-mails. To create a Custom Filter: Open a Web browser (e.g., Netscape, Microsoft Internet Explorer, etc.). Type mail.[domain name].[ext] in the address line. Login to your Network Solutions email account. Click on the Configuration left menu tab. Click on the Custom Filter link. Type the rule name. blah, blah, blah Basically add them one at a time. "We are committed to creating the best Customer experience possible." No you are not. You are trying to squeeze every nickle you can out of me. "With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers." Maybe I should apply for a job to write those ten complicated lines of code... Maybe I should question my choice of vendors, because if they truly "cannot" then they are to stupid to have my business. It is both amusing and sad. I'll be posting this in every forum I am a member of.

  • Drupal Forms - Setting a Default Value

    - by JR
    I am using the webform module for Drupal 6 and would like to set a default value for the confirmation message of the webform whenever it is created. Would I have to create my own module to set this form value whenever a user creates a new webform? Or would I have to implement a special hook to look for when a webform is created?

  • Static Javascript files not loaded in Express app

    - by Dave Long
    I have an express app that has a bunch of static javascript files that aren't being loaded even though they are registered in my app.js file. Even public scripts (like jQuery: http://ajax.googleapis.com/ajax/libs/jquery/1.6.3/jquery.min.js) aren't processing. I can see the script tags in the generated html, but none of the functionality runs and I can't see the files loading in the web inspector. Here is the code that I have: app.js var express = require('express') var app = module.exports = express.createServer(); // Configuration var port = process.env.PORT || 3000; app.configure(function(){ app.set('views', __dirname + '/views'); app.set('view engine', 'jade'); app.use(express.bodyParser()); app.use(express.methodOverride()); app.use(app.router); app.use(express.static(__dirname + '/public')); }); app.configure('development', function(){ app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); }); app.configure('production', function(){ app.use(express.errorHandler()); }); // Routes app.get('/manage/new', function(req, res){ res.render('manage/new', { title: 'Create a new widget' }); }) app.listen(port); console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env); /views/manage/layout.jade !!! 5 html(lang="en") head title= title link(rel="stylesheet", href="/stylesheets/demo.css") link(rel="stylesheet", href="/stylesheets/jquery.qtip.css") script(type="text/javascript", href="http://ajax.googleapis.com/ajax/libs/jquery/1.6.3/jquery.min.js") body!= body script(type="text/javascript", href="/javascripts/jquery.formalize.js") script(type="text/javascript", href="/javascripts/jquery.form.js") script(type="text/javascript", href="/javascripts/jquery.qtip.js") script(type="text/javascript", href="/javascripts/formToWizard.js") script(type="text/javascript", href="/javascripts/widget.js") /views/manage/new.jade h1= title div(style="float:left;") form(action="/manage/generate", method="post", enctype="multipart/form-data", name="create-widget") .errors fieldset legend Band / Album Information fieldset legend Social Networks fieldset legend Download All of my javascript files are stored in /public/javascripts and all of my static CSS files are being served up just fine. I'm not sure what I've done wrong.

  • Is my understanding of "select distinct" correct?

    - by paxdiablo
    We recently discovered a performance problem with one of our systems and I think I have the fix but I'm not certain my understanding is correct. In simplest form, we have a table blah into which we accumulate various values based on a key field. The basic form is: recdate date rectime time system varchar(20) count integer accum1 integer accum2 integer There are a lot more accumulators than that but they're all of the same form. The primary key is made up of recdate, rectime and system. As values are collected to the table, the count for a given recdate/rectime/system is incremented and the values for that key are added to the accumulators. That means the averages can be obtained by using accumN / count. Now we also have a view over that table specified as follows: create view blah_v ( recdate, rectime, system, count, accum1, accum2 ) as select distinct recdate, rectime, system, count, value (case when count > 0 then accum1 / count end, 0), value (case when count > 0 then accum2 / count end, 0) from blah; In other words, the view gives us the average value of the accumulators rather than the sums. It also makes sure we don't get a divide-by-zero in those cases where the count is zero (these records do exist and we are not allowed to remove them so don't bother telling me they're rubbish - you're preaching to the choir). We've noticed that the time difference between doing: select distinct recdate from XX varies greatly depending on whether we use the table or the view. I'm talking about the difference being 1 second for the table and 27 seconds for the view (with 100K rows). We actually tracked it back to the select distinct. What seems to be happening is that the DBMS is actually loading all the rows in and sorting them so as to remove duplicates. That's fair enough, it's what we stupidly told it to do. But I'm pretty sure the fact that the view includes every component of the primary key means that it's impossible to have duplicates anyway. We've validated the problem since, if we create another view without the distinct, it performs at the same speed as the underlying table. I just wanted to confirm my understanding that a select distinct can not have duplicates if it includes all the primary key components. If that's so, then we can simply change the view appropriately.

  • 'javadoc' look-a-like, using parser generator?

    - by wvd
    Hello all, I'm going to create a javadoc look-a-like for the language I'm mainly using, but I was wondering - is it worth to use a parser generator for this? The main idea to use a parser generator was because I could use templates for the HTML code which could be exported then. Also I could also use PDF templates if I need it. Thanks, William v. Doorn

  • What's the pythonic way of declaring variables?

    - by the_drow
    Usually declaring variables on assignment is considered a best practice in VBScript or JavaScript , for example, although it is allowed. Why does Python force you to create the variable only when you use it? Since Python is case sensitive can't it cause bugs because you misspelled a variable's name? How would you avoid such a situation?
