  • i integer does not +1 the 1st time

    - by Hwang
    I have a gallery where it will load an image after a previous image is loaded, so every time 'i' will +1 so that it could move to the next image. This code works fine on my other files, but I dunno why it doesn't work for the current file. Normally if I trace 'i' the correct will be 0,1,2,3,4,5,6... etc adding on till the limit, but this files its 'i' repeat the 1st number twice, only it continues to add 0,0,1,2,3,4,5,6...etc The code is completely the same with the other file I'm using, but I don't know why it just doesn't work here. The code does not seems to have any problem. Anyway i can work around this situation? private var i:uint=0; private function loadItem():void { if (i<myXMLList.length()) { loadedPic=myXMLList[i].thumbnails; galleryLoader = new Loader(); galleryLoader.load(new URLRequest(loadedPic)); galleryLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,picLoaded); } else { adjustImage(); } } private function picLoaded(event:Event):void { var bmp=new Bitmap(event.target.content.bitmapData); bmp.smoothing=true; bmpArray.push(bmp); imagesArray[i].addChild(bmp); i++; loadItem(); }

  • Perl TCP Server handling multiple Client connections

    - by Matt
    I'll preface this by saying I have minimal experience with both Perl and Socket programming, so I appreciate any help I can get. I have a TCP Server which needs to handle multiple Client connections simultaneously and be able to receive data from any one of the Clients at any time and also be able to send data back to the Clients based on information it's received. For example, Client1 and Client2 connect to my Server. Client2 sends "Ready", the server interprets that and sends "Go" to Client1. The following is what I have written so far: my $sock = new IO::Socket::INET { LocalHost => $host, // defined earlier in code LocalPort => $port, // defined earlier in code Proto => 'tcp', Listen => SOMAXCONN, Reuse => 1, }; die "Could not create socket $!\n" unless $sock; while ( my ($new_sock,$c_addr) = $sock->accept() ) { my ($client_port, $c_ip) = sockaddr_in($c_addr); my $client_ipnum = inet_ntoa($c_ip); my $client_host = ""; my @threads; print "got a connection from $client_host", "[$client_ipnum]\n"; my $command; my $data; while ($data = <$new_sock>) { push @threads, async \&Execute, $data; } } sub Execute { my ($command) = @_; // if($command) = "test" { // send "go" to socket1 print "Executing command: $command\n"; system($command); } I know both of my while loops will be blocking and I need a way to implement my accept command as a thread, but I'm not sure the proper way of writing it.

  • Object inside of array -- works in one scope but not in another?

    - by Earlz
    Ok I've been learning some of the more advanced aspects of Javascript and now trying to use this I'm stuck. Here is my code: function Data(){} function init(state){ var item; item=new Data(); item.fieldrid=17; item.description='foo'; state.push(item); }; function findInState(state,fieldrid) { for (var item in state) { alert(item.fieldrid); //prints undefined if (item.fieldrid == fieldrid) { return item; } } return null; } var s=[]; init(s); alert(s[0].fieldrid); //prints 17 (expected) alert(findInState(s,17).fieldrid); //exception here. function returns null. A running example is here at jsbin Why does this not work? I would expect the alert in findInState to yield 17 but instead it yields undefined. What am I doing wrong?

  • Tell bots apart from human visitors for stats?

    - by Pekka
    I am looking to roll my own simple web stats script. The only major obstacle on the road, as far as I can see, is telling human visitors apart from bots. I would like to have a solution for that which I don't need to maintain on a regular basis (i.e. I don't want to update text files with bot-related User-agents). Is there any open service that does that, like Akismet does for spam? Or is there a PHP project that is dedicated to recognizing spiders and bots and provides frequent updates? To clarify: I'm not looking to block bots. I do not need 100% watertight results. I just want to exclude as many as I can from my stats. In know that parsing the user-Agent is an option but maintaining the patterns to parse for is a lot of work. My question is whether there is any project or service that does that already. Bounty: I thought I'd push this as a reference question on the topic. The best / most original / most technically viable contribution will receive the bounty amount.

  • Display latest date from a HTML attribute

    - by Tron
    I currently have several classes which contain a date inside an attribute. <div id="container"> <div class="date" date="19/11/2013"></div> <div class="date" date="06/11/2013"></div> </div> <div id="result"></div> What I would like to do, is find the latest date and display it on the page. So far, I've found the information in the attribute, checked that it doesn't exist in the array then and pushed it into an array. I'm not entirely sure of the best approach from here, but ideally i would like to find the latest date and then append it to the results container. $('.date').each(function () { var dateArray = []; var date = $(this).attr('date'); if ($.inArray(date, dateArray) == -1) { dateArray.push(date); } $('#result').append(dateArray); }); Any assistance on the above would be greatly appreciated. Thanks :)

Any way to do this faster?

  • custom *arbitrary* TemplateField definitions

    - by end-user
    I'm building a GridView on the fly, and I'd like to pre-define the TemplateFields to be included ondemand. So, what I'd like to do is have a declarative file that defines how the different templates look for a specific column. Like: <asp:TemplateField> <HeaderTemplate> this is a text column </HeaderTemplate> <ItemTemplate> data goes here </ItemTemplate> <EditItemTemplate> <asp:TextBox Text="databindhere" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> this is a bool column </HeaderTemplate> <ItemTemplate> if(true) "yes" else "no" </ItemTemplate> <EditItemTemplate> <asp:CheckBox Checked="databindme" /> </EditItemTemplate> </asp:TemplateField> So, if my query had a text and two bool fields, I could push the appropriate TemplateFields in the the Columns property as needed. (I hope I'm making sense here) So, how would I go about creating declarative files for the above definitions? And then, how would I reference those definitions programmatically?

  • What type of data store should I use for my ios app?

    - by mwiederrecht
    I am pretty new to ios and using servers so forgive me. I am building an ios app for research. I need to monitor things that the user does and then push it up to a server for analysis (yes, with user and IRB permission). On the client's side I need to keep quite a bit of data that won't really change except in the case of pulling an updated version from the server, and then a minimal amount of user-specific data. Most of the data I will collect needs to be pushed to a server for analysis and then can be deleted from the client side. I am struggling to figure out what kind of data store I need to use, especially since I am not quite sure how the pushing and pulling from the server process works yet. Does it make sense to use Core Data? XML? SQLite? I like the Core Data idea, but I am not sure what kind of problems I will run into when I need to send large amounts of data to it and from it from the server. I imagine I might need to send data in a different form than it is probably stored in on either end - so what kind of overhead am I likely to run into in the process of converting that data? Is there a good format to save stuff in that would work well for me on both ends AND for sending the data? As you can probably tell, I could use some advice. Thanks!

  • C++: inheritance problem

    - by Helltone
    It's quite hard to explain what I'm trying to do, I'll try: Imagine a base class A which contains some variables, and a set of classes deriving from A which all implement some method bool test() that operates on the variables inherited from A. class A { protected: int somevar; // ... }; class B : public A { public: bool test() { return (somevar == 42); } }; class C : public A { public: bool test() { return (somevar > 23); } }; // ... more classes deriving from A Now I have an instance of class A and I have set the value of somevar. int main(int, char* []) { A a; a.somevar = 42; Now, I need some kind of container that allows me to iterate over the elements i of this container, calling i::test() in the context of a... that is: std::vector<...> vec; // push B and C into vec, this is pseudo-code vec.push_back(&B); vec.push_back(&C); bool ret = true; for(i = vec.begin(); i != vec.end(); ++i) { // call B::test(), C::test(), setting *this to a ret &= ( a .* (&(*i)::test) )(); } return ret; } How can I do this? I've tried two methods: forcing a cast from B::* to A::*, adapting a pointer to call a method of a type on an object of a different type (works, but seems to be bad); using std::bind + the solution above, ugly hack; changing the signature of bool test() so that it takes an argument of type const A& instead of inheriting from A, I don't really like this solution because somevar must be public.

  • callback on a variable which is inside a .each() loop

    - by Stoic
    I have this function, which is doing an asynchronous call to FB.api method. Now, i am looping over some data and capturing result of the above method call successfully. However, I am using a .each loop and I really can not figure out how to place my callback in this method, so that the outer method is only executed once. Here are the functions I am using: ask_for_perms($(this).val(),function(result) { $('#some-div').html('<a onclick = "get_perms(result);" >get perms</a>'); }); function ask_for_perms(perms_requested,cb) { var request = []; $.each(perms_requested,function(i,permission) { FB.api({ method: 'users.hasAppPermission', ext_perm: permission }, function(response) { if (response == 0) request.push(permission); request.join(','); cb(request); // cb is called many times here. }); }); } I am trying to return the request string from ask_for_perms function. Can anyone suggest me on where to place a proper callback to ask_for_perms. Right now, however, it works for me, but the callback is being called many times since it is inside a for loop. referencing: returning a variable from the callback of a function

  • Booking logic and architecture, database sync: Hotels, tennis courts reservation system ...

    - by coulix
    Hello Stackers, Imagine that you want to design a tennis booking system. You have 5 tennis clubs as partenrs with no online api allowing you to check on their side if a court is booked or not: You have to build this part as well. Every time a booking is done on their side you want it to be know by our system. Probably using a POST request form tennis partner to our server. Every time a booking is done on our website, we want to push the booking to their system. The difficulty is that their system need to be online and accessible from outside. Ip may change, we have to use a dns updater. In case their system is not available we still accept the booking and fallback to an async email with 'i confirm booking/reject booking' link sent to the club. I find the whole process quite complex and was wondering about the way online hotel booking system and hotel were working. Do they all have their data open and online ? The good thing is that the data will grow large and fits nicely to some no SQL ;) like couch db

  • Aligning left and right in a simple footer

    - by Wolfram
    I'm currently working on a simple footer, and I would like to align one line of text left and the other to the right. This is what I have so far: <div id="footer"> Last Updated: October 15, 2012 <!--left align--> Contact Us Login <!--right align (these will be links)--> </div> #footer { font-family: Arial; font-size: .9em; color: #24ACAE; border-top: 1px solid #24ACAE; margin-left: 90px; margin-right: 90px; padding-top: 5px; } The above code results in the two lines of text being next to each other and I've tried various ways of fixing this such as putting the the 2nd line in a span and aligning right and even putting the lines into a table. None of what I have tried has resulted in both lines being properly aligned. Using a margin-left alone does not work because when the first line is updated and becomes longer, it will push the second line downwards. Relative positioning seems to have the same issue. Hopefully there's something simple that I'm overlooking.

  • Provider not notified from cookbook_file

    - by wittyhandle
    I'm working on an ssl provider using Vagrant (1.0.5) and chef-solo (10.12.0) I have my provider, called ssl within a cookbook called gtm_cq, I define it as such in my cookbook's default recipe: gtm_cq_ssl "author" do # attributes will come later end I then have my cookbook_file like below that should notify my ssl provider's import action once it pushes the cert up to the server: cookbook_file "#{node[:cq][:ssl][:author_cert_location]}/foo.cer" do source "foo.cer" owner "crx" group "root" mode "0644" notifies :import, resources(:gtm_cq_ssl => "author") end When I run this, the foo.cer gets pushed up as expected, but the import action of my ssl provider is never called. The most I see of any reference is these couple of lines in the log (removed log headers): .. cookbook_file[/opt/cq5/author/foo.cer] sending import action to gtm_cq_ssl[author] (delayed) .. Processing gtm_cq_ssl[author] action import (gtm_cq::author line 34) There's a large very obvious log statement as well as the use of another cookbook_file for a test file to push something up to the server. No log statement, no test file pushed. I'm certain too that the foo.cer file is removed from the server before each test. I found that if I edit my notifies line like so with :immediately notifies :import, resources(:gtm_cq_ssl => "author"), :immediately It seems to work. And I suppose this is ok in my particular case, but it would seem something is not right if that's the only way I can call my provider. Any help on this would be greatly appreciated. Thanks!

  • How do I form a Rails link_to with custom field value as parameter

    - by rwheadon
    I have an invoice form where I'm giving the user opportunity to apply coupons to the invoice total. These coupons are held in another Model and I am going to do a lookup on the Coupon code (something like "20OFFONFRIDAY") which I will use to find what the restrictions and benefits of the coupon. (and to see if it even exists at all) The invoice does not have "coupon_code" on it so I hand forged the field onto my form with html: <% if (@invoice.status == 'new') %> <input id="coupon_code" name="coupon_code" type="text"/> <% end %> and I am calling a controller method with link_to and would like something like the following jquery enhanced link_to to work: <%= link_to "Apply Coupon", { :controller=>"invoices", :id=>@invoice.id, :coupon_code=>$('.coupon_code').val(), :action=>"apply_coupon_code" }, :method=>"post" %> ^formatted for easier reading Then inside my "apply_coupon_code" method I will go off to a couple other models and perform business logic before returning the updated invoice page. ...but maybe it's a pipe dream. I guess if push came to shove I could add the "coupon_code" field to my invoice model (even though it's persisted elsewhere.) so it's part of the entity and thus easily available on my form to send back into a controller, but I just hate adding a column to make a coupon validation easier. I figured I'd ping stackoverflow before taking that path.

Then I updated the code as below $block_started++ if ( ($line =~ /^(status)/) && (index($line, "MaterializeU4") != 25) Now it works. Any comments are welcome about my practice. Thank you.

  • How do I migrate from a basic plaintext password authentication to an OAuth based system?

    - by different
    Hello, Found out today that Twitter will be discontinuing its basic authentication for its API; the push is now towards OAuth but I don’t have a clue as to how to use it or whether it’s the right path for me. All I want to be able to do is post a tweet linking to the most recently published post when I hit publish. Currently I’m sending the login credentials for my Twitter account as plaintext, which I realise isn’t that secure but as my site is fairly small it isn’t an issue at least for now. I’m using this basic PHP code: $status = urlencode(stripslashes(urldecode("Test tweet"))); $tweetUrl = 'http://www.twitter.com/statuses/update.xml'; $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, "$tweetUrl"); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 2); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, "status=$status"); curl_setopt($curl, CURLOPT_USERPWD, "$username:$password"); $result = curl_exec($curl); $resultArray = curl_getinfo($curl); if ($resultArray['http_code'] == 200) { curl_close($curl); $this->redirect(""); } else { curl_close($curl); echo 'Could not post to Twitter. Please go back and try again.'; } How do I move from this to an OAuth system? Do I need to?

  • How to add an object to a html string?

    - by Philippe Maes
    I'm trying to load several images by a drop action and than resizing them and adding them as a thumbnail. The resize part is very important because the images can be very large and I want to make the thumbnails small of size. Here is my code: loadingGif(drop); for (var i=0;i<files.length;i++) { var file = files[i]; var reader = new FileReader(); reader.onload = function(e) { var src = e.target.result; var img = document.createElement('img'); img.src = src; var scale = 100/img.height; img.height = 100; img.width = scale*img.width; output.push('<div id="imagecontainer"><div id="image">'+img+'</div><div id="delimage"><img src="img/del.jpg"" /></div></div>'); if(output.length == files.length) { drop.removeChild(drop.lastChild); drop.innerHTML += output.join(''); output.length = 0; } } reader.readAsDataURL(file); } As you can probably tell I insert a loading gif image in my dropzone until all files are loaded (output.length == files.length). When a file is loaded I add html to an array which I will print if the load is complete. The problem is I can't seem to add the img object (I need this object to resize the image) to the html string, which seems obvious as the img is an object... So my question to you guys is: how do I do this? :)

  • Getting memory leak at NSURL connection in Iphone sdk.

    - by monish
    Hi guys, Here Im getting leak at the NSURL connection in my libxml parser can anyone tell how to resolve it. The code where leak generates is: - (BOOL)parseWithLibXML2Parser { BOOL success = NO; ZohoAppDelegate *appDelegate = (ZohoAppDelegate*) [ [UIApplication sharedApplication] delegate]; NSString* curl; if ([cName length] == 0) { curl = @"https://invoice.zoho.com/api/view/settings/currencies?ticket="; curl = [curl stringByAppendingString:appDelegate.ticket]; curl = [curl stringByAppendingString:@"&apikey="]; curl = [curl stringByAppendingString:appDelegate.apiKey]; curl = [curl stringByReplacingOccurrencesOfString:@"\n" withString:@""]; } NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:curl]]; NSLog(@"the request parserWithLibXml2Parser %@",theRequest); NSURLConnection *con = [[[NSURLConnection alloc] initWithRequest:theRequest delegate:self] autorelease];//Memory leak generated here at this line of code. //self.connection = con; //[con release]; // This creates a context for "push" parsing in which chunks of data that are // not "well balanced" can be passed to the context for streaming parsing. // The handler structure defined above will be used for all the parsing. The // second argument, self, will be passed as user data to each of the SAX // handlers. The last three arguments are left blank to avoid creating a tree // in memory. _xmlParserContext = xmlCreatePushParserCtxt(&simpleSAXHandlerStruct, self, NULL, 0, NULL); if(con != nil) { do { [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]; } while (!_done && !self.error); } if(self.error) { //NSLog(@"parsing error"); [self.delegate parser:self encounteredError:nil]; } else { success = YES; } return success; } Anyone's help will be muck appreciated . Thank you, Monish.

  • Add values to an array after isset()

    - by user1656692
    I'm trying to add elements to an array after subsequent trials, but so far only one value is being added to the array. I've Googled and searched stackoverflow, and I seem to be getting only half the picture unless if I'm implementing it wrong. There are about 40 files, which will be needed to be submited one after another, and then a value from each trial is stored in the database. So far, this is what I've done. $_SESSION['task2'] = array(); //Submit Task 1 if (isset($_POST['submit_task_01'])) { $trial1_ac_sec = cleanInput($_POST['clockInputTask_01ac']); $trial1_est_sec = cleanInput($_POST['clockInputTask_01']); $trial1_ac = round(($trial1_ac_sec * 42.67), 2); $trial1_est = round(($trial1_est_sec * 42.67), 2); $trial1_judgErr = $trial1_ac - $trial1_est; $trial_1error = round($trial1_judgErr, 2); array_push($_SESSION['task2'],$trial_1error); header("location: Trial_2.php"); } //Submit Task2 if (isset($_POST['submit_task_02'])) { $trial2_ac_sec = cleanInput($_POST['clockInputTask_02ac']); $trial2_est_sec = cleanInput($_POST['clockInputTask_02']); $trial2_ac = round(($trial2_ac_sec * 42.67), 2); $trial2_est = round(($trial2_est_sec * 42.67), 2); $trial2_judgErr = $trial2_ac - $trial2_est; $trial_2error = round($trial2_judgErr, 2); array_push($_SESSION['task2'],$trial_2error); header("location: newEmptyPHPWebPage.php"); } ... and so on.. up until 40 I'm just wondering what am I doing wrong, I know that each time isset() will reload the page, and the previous data won't be available, so in that sense I thought I'd create an array for sessions and then push data in the session, however that doesn't seem to work. If anyone has any ideas on what I can do, I'll greatly appreciate it. Thank You.
