  • Loading table sections when using headers

    - by Luis Tovar
    I cant seem to wrap my head around this. I have googled, and overstacked for hours now looking for examples that i can relate to. What I have is two arrays. The name of my first NSMutableArray is "showDates". I have 3 objects in here. Object 0: "Today, May 20th" Object 1: "Tomorrow, May 21st" Object 2: "Saturday, May 22nd" Then I have my second NSMutableArray named "showTimes" I have about 15 objects in there with strings in each object. ( i hope that makes sense? ) Each object is structured like this: Object 0: showID @"98022" eventID @"833" showTime @"1:30pm" showDate @"Today, May 20th" auditorium @"9" venue @"2991" Object 1: showID @"98222" eventID @"813" showTime @"2:30pm" showDate @"Tomorrow, May 21st" auditorium @"9" venue @"2991" Etc, etc, .... I have the headers working great in my tableView, but I cant seem to figure out how to add the objects in my "showTimes" array under the correct header. Any help would be greatly appreciated.

  • How to stop/override a Jquery TimeOut function?

    - by Tom
    Hi, I have a small jquery snippet that displays notification message at the top of the screen in response to user actions on a page. The notification is often displayed after Ajax actions with dynamic content inside it. For example: $("#mini-txt").html("Thank you!"); $("#mini").fadeIn("fast"); setTimeout(function() {$("#mini").animate({height: "hide", opacity: "hide"}, "medium");}, 3000); The notification works well, except when a user does two or more actions in rapid succession, in which case the TimeOut function will confuse itself and the second message appears to come inside the previous 3000 milliseconds. Is there a way to "kill" the previous notification if a new action is performed. I've got no problem with the actions/selectors, just the TimeOut function.... either stopping it or overriding it somehow. Or perhaps there's a better alternative for getting the message to linger on the screen for a few seconds before disappearing? Thank you.

  • Extjs - Loading Grid when call

    - by Oxi
    I have form and grid. the user must enter data in form fields then display related records in the grid. I want to implement a search form, e.g: user will type the name and gender of the student, then will get a grid of all students have the same name and gender. So, I use ajax to send form fields value to PHP and then creat a json_encode wich will be used in grid store. I am really not sure if my idea is good. But I haven't found another way to do that. The problem is when I set autoLoad to true in the store, the grid automatically filled with all data - not just what I asked for - So, I understand that I have to set autoLoad to false, but then the result not shown in the grid even it returned successfully in the firebug! I don't know what to do. My View: { xtype: 'panel', layout: "fit", id: 'searchResult', flex: 7, title: '<div style="text-align:center;"/>SearchResultGrid</div>', items: [ { xtype: 'gridpanel', store: 'advSearchStore', id: 'AdvSearch-grid', columns: [ { xtype: 'gridcolumn', dataIndex: 'name', align: 'right', text: 'name' }, { xtype: 'gridcolumn', dataIndex: 'gender', align: 'right', text: 'gender' } ], viewConfig: { id : 'Arr' ,emptyText: 'noResult' }, requires: ['MyApp.PrintSave_toolbar'], dockedItems: [ { xtype: 'PrintSave_tb', dock: 'bottom', } ] } ] }, My Store and Model: Ext.define('AdvSearchPost', { extend: 'Ext.data.Model', proxy: { type: 'ajax', url: 'AdvSearch.php', reader: { type: 'json', root: 'Arr', totalProperty: 'totalCount' } }, fields: [ { name: 'name'}, { name: 'type_and_cargo'} ] }); Ext.create('Ext.data.Store', { pageSize: 10, autoLoad: false, model: 'AdvSearchPost', storeId: 'AdvSearchPost' });

  • Ria Services loading foreign keys with Linq-to-SQL

    - by Stephan
    I have a database that consists of 5 tables : Course, Category, Location, CourseCategories, and CourseLocations. The last 2 tables just contain the two foreign keys. A Course has many-to-many relationships with both category and location. I am trying to load the data into a Silverlight app using Ria Services. My DB model is Linq-to-SQL. I have tried adding the [Include] attribute to the metadata classes and I have added the DataLoadOptions so it should load the all tables when you ask for a Course. However on the client side I am never getting back any entries in the CourseCategories and CourseLocations properties. What else needs to be done to get the foreign key relationships to exist across the serialization.

  • stop android emulator call

    - by Shahzad Younis
    I am working on an Android application, having functionality like voicemail. I am using BroadcastReceiver to get dialing events. I have to get the event "WHEN CALL IS UNANSWERED (not picked after few rings) FROM RECEIVER". I will do some actions on caller end against this event. I am using AVD emulator, and I do call from one instance to another instance and it calls perfectly, but the problem is: It continuously calls until I reject or accept the call. This way I cannot detect that "CALL IS UNANSWERED AFTER A NUMBER OF RINGS". So I want the Caller emulator to drop the call after a number of rings (if unanswered) like a normal phone. I can do it (drop the call after some time) by writing some code, but I need the natural functionality of phone in the emulator. Can anyone please guide me? Is there any settings in the emulator? Or something else? The code is shown below in case it helps: public class MyPhoneReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Bundle extras = intent.getExtras(); if (extras != null) { String state = "my call state = " + extras.getString(TelephonyManager.EXTRA_STATE); Log.w("DEBUG", state); } }

  • Storing and loading a subtitle of an annotation with NSUserDefualts

    - by Krismutt
    Happy new year everybody! Basically, what I try to do is to save a subtitle to an annotation when the application terminates. When the application starts again I want this stored subtitle to show up in the callout of the annotation again. What am I doing wrong? I just can't get it to work... storeLocation.m - (void)setCoordinate:(CLLocationCoordinate2D)coor { MKReverseGeocoder *geocoder = [[[MKReverseGeocoder alloc] initWithCoordinate:coor] autorelease]; geocoder.delegate = self; coordinate = coor; [geocoder start]; NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults]; [userDef setValue:subtitle forKey:@"SavedAddress"]; [userDef synchronize]; NSLog(@"Sparade adress"); } mainViewController.m -(void)viewDidLoad { NSString *savedAddress = [[NSUserDefaults standardUserDefaults] objectForKey:@"SavedAddress"]; if (savedAddress) { // what code should I add here // so that the subtitle shows up // when the application launches? } } Would really appreciate some help with this one... Thanks in advance!

  • Loading non-RJS javascript via ajax in Rails

    - by David Smith
    I've written a rails module that generates some javascript for a google map. As the user makes changes on the webpage, I use observe_field to call back to the server to regenerate the map's javascript (without updating the whole page). I'm having trouble finding a good way to insert the new javascript into the page. I've tried <div id='my_div_1'>div1</div> <%= update_page_tag do |page| page.replace_html 'my_div_1', "<script>alert('hi');</script>" end %> but it seems that replace_html only works for non-script html. It chokes when the content includes the closing < /script tag. Additional information...here is a page that I think is the root of the problem. http://www.wwco.com/~wls/blog/2007/04/25/using-script-in-a-javascript-literal/

  • How to stop GHC from generating intermediate files?

    - by unknown
    When compiling a haskell source file via ghc --make foo.hs GHC always leaves behind a variety of intermediate files other than foo.exe. These are foo.hi and foo.o. I often end up having to delete the .hi and .o files to avoid cluttering up the folders. Is there a command line option for GHC not to leave behind its intermediate files? (When asked on #haskell, the best answer I got was ghc --make foo.hs && rm foo.hi foo.o.

  • Incompatible classes when loading SWF

    - by Bart van Heukelom
    I have two ActionScript 3 projects, game(.swf) and minigame(.swf). At runtime the main game loads the minigame via Loader. I also have a shared library (SWC) of event classes, included by both, which minigame will need to dispatch and game will need to listen to. First: Is this possible this way? Second: What will happen if I compile the minigame, then change the event classes so they're incompatible, then compile the main game. Will Flash crash when trying to load the minigame SWF? (I hope so) Third: And what will happen if I change the event classes, but in a way that preserves interface-level compatibility?

  • Loading images to UIScrollview crashes

    - by Icky
    Hello All. I have a Navigationcontroller pushing a UIViewController with a scrollview inside. Within the scrollview I download a certain number of images around 20 (sometimes more) each sized around 150 KB. All these images are added to the scrollview so that their origin is x +imageSize and the following is sorted right to the one before. All in all I think its a lot of data (3-4 MB). On an I pod Touch this sometimes crashes, the IPhone can handle it once, if it has to load the data again (some other images) , it crashes too. I guess its a memory issue but within my code, I download the image, save it to a file on the phone as NSData, read it again from file and add it to a UIImageview which I release. So I have freed the memory I allocated, nevertheless it still crashes. Can anyone help me out? Since Im new to this, I dont know the best way to handle the Images in a scrollview. Besides I create the controller at start from nib, which means I dont have to release it, since I dont use alloc - right? Code: In my rootviewcontroller I do: -(void) showImages { [[self naviController] pushViewController:imagesViewController animated:YES]; [imagesViewController viewWillAppear:YES]; } Then in my Controller handling the scroll View, this is the method to load the images: - (void) loadOldImageData { for (int i = 0; i < 40 ; i++) { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *filePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"img%d.jpg", i]]; NSData *myImg = [NSData dataWithContentsOfFile:filePath]; UIImage *im = [UIImage imageWithData:myImg]; if([im isKindOfClass:[UIImage class]]) { NSLog(@"IM EXISTS"); UIImageView *imgView = [[UIImageView alloc] initWithImage:im]; CGRect frame = CGRectMake(i*320, 0, 320, 416); imgView.frame = frame; [myScrollView addSubview:imgView]; [imgView release]; //NSLog(@"Adding img %d", i); numberImages = i; NSLog(@"setting numberofimages to %d", numberImages); //NSLog(@"scroll subviews %d", [myScrollView.subviews count]); } } myScrollView.contentSize = CGSizeMake(320 * (numberImages + 1), 416); }

  • Java applet loading images from external jars

    - by Mathias
    I have a jar on a server, and users should be able to develop extensions for it. Therefore the jars main class should be extended and some resources should be added to a second user created jar which will be loaded from another server or locally. Now I have problems accessing the resources (images) from the user loaded jars. Heres is the structure: My Server: game.jar containing game.class images.class ... image1.png (...) Local: user.jar containing: user.class extends game userimage.png The extension is loaded via Greasemonkey, it modifies the "archive" attribute to "/home/username/user.jar, game.jar" and the "code" attribute to "user.class". The user should be able to overwrite already defined images. If the image does not exist in game.jar, it is loaded correctly from user.jar. But the images loaded early in the game are always loaded from the game.jar, others seem to be overwritten correctly by the user. Is there a way to make sure they are always loaded in the correct order? This might be because of some caching mechanism. Because Greasemonkey removes the game from the page, changes the archive and code and reinsert it, the game is loaded without a mod for a brief second. In that time, images are loaded as expected from game jar, but those are the ones not being overwritable by the user. But how to avoid it? Another thing: If I overwrite the "run" method in user.class, the game is unable to load any image at all. Not from the user.jar and not from the game.jar. Java doesn't find the image, as the URL object "getClass().getResource(imagename)" returns with null. I tried to overwrite the image.class, but that doesn't fix the problem, unless I overwrite every class from game.class involved into calling the image.class

    I am using html, tag: <input type = "file" /> On android and on many cellulars I have the ability to get the file directly by taking a picture and save it. How can I know (by javascript code) how did I get the picture (direcly by the camera, or by some files that on my cellular)? I did some workarround, and found exif (http://www.nihilogic.dk/labs/exif/exif.js), but I didn't succeed using it, either I don't know whether exif is the right solution. Thanks :)

  • How to start/stop/restart jQuery animation

    - by Emin
    I have the following function that when I call displays a message to the user for a certain amount of time (5 secs in my case). During this "period" if I call the function again to display another message, practically it should hide, then re-appear with the new message for another 5 seconds. What happens with my code below, I call the function to display the message. Then, lets say on the 4th second, I call it again to display another message, the new message is displayed for 1 second. I need to somehow -reset- the time but can't figure out how. Tried stopping the animation, checking if the element was visible and hiding it if it was, and many other things. I believe the solution is a simple chaining issue but can't get it right. So any help would be appreciated! function display_message(msgType, message) { var elem = $('#ur_messagebox'); switch (msgType) { case 'confirm': elem.addClass('msg_confirm'); break; case 'error': elem.addClass('msg_error'); break; } elem.html(message); elem.show().delay(5000).fadeOut(1000); } thanks in advance...

  • How to stop expanding an infinite SWT Tree upon pressing "*"

    - by Lóránt Pintér
    I have an SWT Tree in my application that contains an infinite data structure. Upon expanding an item, I generate its children. On Windows though, users can press "*", triggering an "expand all descendants" action, and my application hangs. There are two acceptable behaviors for me when the user presses "*": Expand all children of the selected element, but only to the next level Do nothing In either case, I will still need to be able to expand items as deep as required (by clicking on the [+] icon, or by pressing "+"), so limiting the tree depth is not a solution. Is there another way that I can achieve either of the above without modifying SWT classes?

  • Problem with IE 6 page loading.

    - by Puneet Dudeja
    I have a website which works fine in all browsers except in IE6. The pages content is inside a div loaded with a background image. The page layout gets very nasty and image does not load when the page is opened for first time, but when the same page is opened for the second time and any subsequent times, then it loads perfectly. This scenario is with every page in the site. Please help.

  • Why does Android allocate more memory than needed when loading images

    - by Simon
    Folks, I don't think that this is a duplicate and is NOT one of those how do I avoid OOMs questions. This is a genuine quest for knowledge so hold off on those down votes please... Imagine I have a JPEG of 500x500 pixels. I load it as ARGB_8888 which is as "bad as it gets". I would expect Android to allocate 500x500x4 bytes = a little under 1MB however, look at a heap dump and you will see that Android allocates significantly more, often factors of 5-10 times greater. You frequently see questions on here about OOMS where the stack trace shows a heap request of say 15MB and it is ALWAYS much larger than is required simply to hold the bytes of the image. The OP usually catches some downvotes then is bombarded with stock answers and comments about using less memory (thanks Romain!) and in scaling. I think there is more than meets the eye here. Anybody know why this is? If there is no apparent answer, I will put together an SSCCE if it helps. PS. I assume that JPEG vs PNG etc is irrelevant since we're talking about the memory usage of the backing bitmap which is simply x times y times BPP - or am I being slow?

  • How to load a jar file at runtime

    - by Amir Arad
    Hi, I was asked to build a java system that will have the ability to load new code (expantions) while running. How do I re-load a jar file while my code is running? or how do I load a new jar? Obviously, since constant up-time is important, I'd like to add the ability to re-load existing classes while at it (if it does not complicate things too much). What are the things I should look out for? (think of it as two different questions - one regarding reloading classes at runtime, the other regarding adding new classes).

  • Stop setInterval within jQuery plugin

    - by Romelus
    I am trying to wrap up a plugin that I am writing but am stumped on a very trivial problem that I cant seem to find a solution for. I have tracked down almost every forum and related problem discussion. Any ways here is what I want to happen, my plugin has a timer that I would like the user to be able to handle its termination. (function ($) { ... var defaults = { callback : function(){}, crossfadeTime : 1000, easing : 'linear', running : 'true', // Here is where I would like the user to send a parameter // to invoke a different result. i.e. 'false' => clearing // the timer. Such as... var timer = setInterval(function(){ // Do Something; },3000); if(defaults.running == 'false'){ clearInterval(timer); }

  • Checking lazy loaded properties have been instantiated

    - by PaulG
    In a class which has a lazy loaded property, such as: private Collection<int> someInts; public Collection<int> SomeInts { get { if (this.someInts == null) this.someInts = new Collection<int>(); return this.someInts; } } Is it worth also having a property such as: public bool SomeIntsExist { get { return (this.someInts != null && this.someInts.Count > 0); } } And then using that property.. eg: if (thatClass.SomeIntsExist) { // do something with thatClass.SomeInts collection } or is this premature optimisation. Its certainly easier to roll with something like below, but it will instantiate the collection needlessly: if (thatClass.SomeInts.Count > 0) { // do something with thatClass.SomeInts collection } Is the compiler smart enough to figure things like this out? Is there a better way?
