  • Passing a NSArray between classes

    - by Althane
    So, my second question based off of this application I'm teaching myself Objective C with. I have a Data Source class, which for now looks mostly like: - (id) init { if (self = [super init]){ listNames = [[NSArray alloc] initWithObjects: @"Grocery", @"Wedding", @"History class",@"CS Class",@"Robotics",@"Nuclear Sciences", @"Video",@"Library",@"Funeral", nil]; NSLog(@"%@",listNames); } return self; } The .h looks as follows: @interface MainViewDataSource : NSObject { NSArray *listNames; } @property (nonatomic, retain) NSArray *listNames; -(NSArray *)getListNames; So that's where I make it. Now the problem is that when I try to get the array listNames, it returns nothing. The following piece: NSArray* data = [listData listNames]; Is supposed to put the information in listNames in data, but... isn't. Since I'm rather used to JAva, I'm betting this is an Objective C quirk that I don't know how to fix. Which is why I'd be here asking for help. What's the proper way to pass around NSArrays like this?

  • NullPointerException and the best way to deal with it

    Note: This is homework/assignment feel not to answer if you don't want to. Ok after some search and reading these: http://stackoverflow.com/questions/425439/how-to-check-if-array-element-is-null-to-avoid-nullpointerexception-in-java http://stackoverflow.com/questions/963936/gracefully-avoiding-nullpointerexception-in-java http://c2.com/cgi/wiki?NullPointerException Am still not making any progress on how to deal with NullPointerException error on my code, snippet for questionable code: int findElement(String element) { int retval = 0; for ( int i = 0; i < setElements.length; i++) { if ( setElements[i].equals(element) ) { // This line 31 here return retval = i; } else { return retval = -1; } } return retval; } void add(String newValue) { int elem = findElement(newValue); if( numberOfElements < maxNumberOfElements && elem != -1 ) { setElements[numberOfElements] = newValue; numberOfElements++; } else { System.out.println("Element " + newValue + "already exist"); } } It compile but adding new element to a set throws a NullPointerException error.

  • Laravel - public layout not needed in every function

    - by fischer
    I have just recently started working with Laravel. Great framework so far! However I have a question. I am using a layout template like this: public $layout = 'layouts.private'; This is set in my Base_Controller: public function __construct(){ //Styles Asset::add('reset', 'css/reset.css'); Asset::add('main', 'css/main.css'); //Scripts Asset::add('jQuery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js'); //Switch layout template according to the users auth credentials. if (Auth::check()) { $this -> layout = 'layouts.private'; } else { $this -> layout = 'layouts.public'; } parent::__construct(); } However I get an error exception now when I try to access functions in my diffrent controllers, which should not call any view, i.e. when a user is going to login: class Login_Controller extends Base_Controller { public $restful = true; public function post_index() { $user = new User(); $credentials = array('username' => Input::get('email'), 'password' => Input::get('password')); if (Auth::attempt($credentials)) { } else { } } } The error I get, is that I do not set the content of the different variables in my public $layout. But since no view is needed in this function, how do I tell Laravel not to include the layout in this function? The best solution that I my self have come a cross (don't know if this is a bad way?) is to unset($this -> layout); from function post_index()... To sum up my question: how do I tell Laravel not to include public $layout in certain functions, where a view is not needed? Thanks in advance, fischer

  • undefined method `build_users' with nested models

    - by Cédric
    I've got into trouble with nested attributes. Here is my Account model : class Account < ActiveRecord::Base has_many :products has_many :blogs has_many :openings has_many :users has_one :logo, :class_name => "AccountPicture" has_one :address, :class_name => "AccountAddress" has_and_belongs_to_many :options accepts_nested_attributes_for :logo, :allow_destroy => true accepts_nested_attributes_for :address, :allow_destroy => true accepts_nested_attributes_for :users, :allow_destroy => true end And here is my User model : class User < ActiveRecord::Base belongs_to :account end As you can see, Account accepts nested attributes for logo, address, and users. While testing, i can use nested attributes for logo and address, but not for user. a = Account.new => #<Account id: nil, hostname: nil, subdomain: nil, name: nil, description: nil, base_line: nil, footer: nil, phone_number: nil, mobile_number: nil, email_address: nil, created_at: nil, updated_at: nil> # building the address works fine >> a.build_address => #<AccountAddress id: nil, account_id: nil, country: nil, state: nil, county: nil, city: nil, suburb: nil, zipcode: nil, street: nil, streetno: nil, longitude: nil, latitude: nil, error_code: nil> # building the users fails >> a.build_users NoMethodError: undefined method `build_users' for #<Account:0x7f6862a5f948> from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/attribute_methods.rb:260:in `method_missing' from (irb):2 Thus, in my views, when i use the nested forms, i got this error back : User(#69850615730460) expected, got Array(#69850664775200) Any help would be appreciated.

  • Unable to run Ajax Minifier as post-build in Visual Studio.

    - by James South
    I've set up my post build config as demonstrated at http://www.asp.net/ajaxlibrary/ajaxminquickstart.ashx I'm getting the following error though: The "JsSourceFiles" parameter is not supported by the "AjaxMin" task. Verify the parameter exists on the task, and it is a settable public instance property. My configuration settings...... <Import Project="$(MSBuildExtensionsPath)\Microsoft\MicrosoftAjax\ajaxmin.tasks" /> <Target Name="AfterBuild"> <ItemGroup> <JS Include="**\*.js" Exclude="**\*.min.js" /> </ItemGroup> <ItemGroup> <CSS Include="**\*.css" Exclude="**\*.min.css" /> </ItemGroup> <AjaxMin JsSourceFiles="@(JS)" JsSourceExtensionPattern="\.js$" JsTargetExtension=".min.js" CssSourceFiles="@(CSS)" CssSourceExtensionPattern="\.css$" CssTargetExtension=".min.css" /> </Target> I had a look at the AjaxMinTask.dll with reflector and noted that the publicly exposed properties do not match the ones in my config. There is an array of ITaskItem called SourceFiles though so I edited my configuration to match. <Import Project="$(MSBuildExtensionsPath)\Microsoft\MicrosoftAjax\ajaxmin.tasks" /> <Target Name="AfterBuild"> <ItemGroup> <JS Include="**\*.js" Exclude="**\*.min.js" /> </ItemGroup> <ItemGroup> <CSS Include="**\*.css" Exclude="**\*.min.css" /> </ItemGroup> <AjaxMin SourceFiles="@(JS);@(CSS)" SourceExtensionPattern="\.js$;\.css$" TargetExtension=".min.js;.min.css"/> </Target> I now get the error: The "SourceFiles" parameter is not supported by the "AjaxMin" task. Verify the parameter exists on the task, and it is a settable public instance property. I'm scratching my head now. Surely it should be easier than this? I'm running Visual Studio 2010 Ultimate on a Windows 7 64 bit installation.

  • How to add a badge to the system generated "More" UITabBarItem

    - by Mark Hoffman
    My app has 6 menu items, so the OS shows the first 4, then shows a "More" item that links to a screen where the user can select the other two. My problem is that I want to show a badge on the More item so that the user knows that one of the menu items that is hidden needs their attention. (It's clear to our users which hidden item the badge represents since one of the hidden items is Settings and the other is current Uploads) I don't know how to access the "More" item since the "items" array on UITabBar only contains the 6 actual UITabBarItems that I've created; it doesn't include the system generated "More" item. I've tried setting the badge on one of the hidden UITabBarItems, but no badge is ever displayed. I didn't find much on Google, which makes me wonder if I'm going about this completely wrong. The iTunes app does the same thing when you download items. They display a More item and attach a badge to it, so I figured I was in good company, but I'll be damned if I see how they did that. (Unless they manually created a UITabBarSystemItemMore item and manually handled displaying the other menu items. Ugh.)

  • Error handling in Rails Controller for adding embedded Mongoid documents to Model

    - by Dragonfly
    I have a Item model that has embedded documents. Currently, the following comments_controller code will add a comment to the item successfully.

  • A Question about .net Rfc2898DeriveBytes class?

    - by IbrarMumtaz
    What is the difference in this class? as posed to just using Encoding.ASCII.GetBytes(string object); I have had relative success with either approach, the former is a more long winded approach where as the latter is simple and to the point. Both seem to allow you to do the same thing eventually but I am struggling to the see the point in using the former over the latter. The basic concept I have been able to grasp is that you can convert string passwords into byte arrays to be used for e.g a symmetric encryption class, AesManaged. Via the RFC class but you get to use SaltValues and password when creating your rfc object. I assume its more secure but still thats an uneducated guess at best ! Also that it allows you to return byte arrays of a certain size, well something like that. heres a few examples to show you where I am coming from? byte[] myPassinBytes = Encoding.ASCII.GetBytes("some password"); or string password = "P@%5w0r]>"; byte[] saltArray = Encoding.ASCII.GetBytes("this is my salt"); Rfc2898DeriveBytes rfcKey = new Rfc2898DeriveBytes(password, saltArray); The 'rfcKey' object can now be used towards setting up the the .Key or .IV properties on a Symmetric Encryption Algorithm class. ie. RijndaelManaged rj = new RijndaelManaged (); rj.Key = rfcKey.Getbytes(rj.KeySize / 8); rj.IV = rfcKey.Getbytes(rj.Blocksize / 8); 'rj' should be ready to go ! The confusing part ... so rather than using the 'rfcKey' object can I not just use my 'myPassInBytes' array to help set-up my 'rj' object???? I have tried doing this in VS2008 and the immediate answer is NO ! but have you guys got a better educated answer as to why the RFC class is used over the other alternative I have mentioned above and why????

  • picturebox image randomisation C#

    - by cheesebunz
    Hi everyone, i am working on a puzzle slider program and trying to randomize images inside of pictureboxes. I did some research on the internet can't find any examples i could work on. These are my code: Random r = new Random(); PictureBox[] picBox = new PictureBox[9]; picBox[0] = new PictureBox(); picBox[1] = new PictureBox(); picBox[2] = new PictureBox(); picBox[3] = new PictureBox(); picBox[4] = new PictureBox(); picBox[5] = new PictureBox(); picBox[6] = new PictureBox(); picBox[7] = new PictureBox(); picBox[8] = new PictureBox(); i have bitmap array too: Bitmap[] pictures = new Bitmap[9]; pictures[0] = new Bitmap(@"1.1Bright.jpg"); pictures[1] = new Bitmap(@"1.2Bright.jpg"); pictures[2] = new Bitmap(@"1.3Bright.jpg"); pictures[3] = new Bitmap(@"2.1Bright.jpg"); pictures[4] = new Bitmap(@"2.2Bright.jpg"); pictures[5] = new Bitmap(@"2.3Bright.jpg"); pictures[6] = new Bitmap(@"3.1Bright.jpg"); pictures[7] = new Bitmap(@"3.2Bright.jpg"); pictures[8] = new Bitmap(@"3.3Dark.jpg"); i tried a few ways but i don't know how to set random pictures[] into the picBox[]: for(int i=0; i<=8;i++) { picBox[i].Image= pictures[r.Next(0,9)]; } the problem here is that some pictureboxes e.g picBox[1] and picBox[6] are repeated pictures. How do i make them non repeats? Examples are greatly appreciated thanks.

  • Unexpected result in C algebra for search algorithm.

    - by Rhys
    Hi, I've implemented this search algorithm for an ordered array of integers. It works fine for the first data set I feed it (500 integers), but fails on longer searches. However, all of the sets work perfectly with the other four search algorithms I've implemented for the assignment. This is the function that returns a seg fault on line 178 (due to an unexpected negative m value). Any help would be greatly appreciated. CODE: 155 /* perform Algortihm 'InterPolationSearch' on the set 156 * and if 'key' is found in the set return it's index 157 * otherwise return -1 */ 158 int 159 interpolation_search(int *set, int len, int key) 160 { 161 int l = 0; 162 int r = len - 1; 163 int m; 164 165 while (set[l] < key && set[r] >= key) 166 { 167 168 printf ("m = l + ((key - set[l]) * (r - l)) / (set[r] - set[l])\n"); 169 170 printf ("m = %d + ((%d - %d) * (%d - %d)) / (%d - %d);\n", l, key, set[l], r, l, set[r], set[l]); 171 m = l + ((key - set[l]) * (r - l)) / (set[r] - set[l]); 172 printf ("m = %d\n", m); 173 174 #ifdef COUNT_COMPARES 175 g_compares++; 176 #endif 177 178 if (set[m] < key) 179 l = m + 1; 180 else if (set[m] > key) 181 r = m - 1; 182 else 183 return m; 184 } 185 186 if (set[l] == key) 187 return l; 188 else 189 return -1; 190 } OUTPUT: m = l + ((key - set[l]) * (r - l)) / (set[r] - set[l]) m = 0 + ((68816 - 0) * (100000 - 0)) / (114836 - 0); m = -14876 Thankyou!

  • Inserting a Variable String into the javascript prototype expression

    - by webzide
    Dear experts, Pardon me for giving you a confusing title on this problem. I'm really confused and i don't know how to put it in other words. So here is what I what to accomplish. I am making a Custom Javascript Object to store data. I have automated this process and inserted each instance of the object into an array. I am making a loop statement to invoke the unique property value of each instance of the object. When I want to use an expression, the property name of the object would be variable since i don't know which one it is. Basically I need to incorporate a string value into the prototype expression. e.g document.getElementById('text').style."fontsize"=value; since I cannot do this directly, i thought possibly I could use the eval function: eval('document.getElementById("text").style.' + buttons[i].cssvalue + '="39px";'); but this still doesn't work. Can this be fixed or ss there an alternative way to accomplish this? If there are some unclear stuff, please point out and I will try to elaborate. Thanks in advance.

  • ez components and AWS PHP SDK makes ez components freak out

    - by David
    Hi, I try to work with ez Components and AWS PHP SDK at the same time. I have a file called resize.php which is just handling resizing images using the ez Components ImageTransition tools. I queue the image for resize in Amazon AWS SQS. If I load the AWS PHP SDK and ez Components in the same file, PHP always complains about not finding the ez Components classes. Code looks something like this: amazonSQS.php: require 'modules/resize.php'; require 'modules/aws/sdk.class.php'; $sqs = new AmazonSQS(); $response = $sqs->send_message($queue_url, $message); resize.php: function resize_image($filename) { $settings = new ezcImageConverterSettings( array( //new ezcImageHandlerSettings( 'GD', 'ezcImageGdHandler' ), new ezcImageHandlerSettings( 'ImageMagick', 'ezcImageImagemagickHandler' ), ) ); Error message: Fatal error: Class 'ezcImageConverterSettings' not found in /home/www.com/public_html/modules/resize.php on line 10 If I call resize.php from another PHP file which has AWS not included, it works fine. I load ezComponents like this: require 'ezc/Base/ezc_bootstrap.php'; It is installed as a PEAR package. Any idea someone?

  • How to set up Hierarchical Zend Rest Routes?

    - by Kenji Baheux
    With the Zend Framework, I am trying to build routes for a REST api on resources organized in the following pattern: http://example.org/users/ http://example.org/users/234 http://example.org/users/234/items http://example.org/users/234/items/34 How do I set up this with Zend_Rest_Route? Here is how I have setup the route for the users resource (users/:id) in my bootstrap.php file: $this->bootstrap('frontController'); $frontController = Zend_Controller_Front::getInstance(); $restRoute = new Zend_Rest_Route($frontController); $frontController->getRouter()->addRoute('default', $restRoute); [As far as I understand, this is a catch all route so users/324/items/34 would results in parameters set as id=324 and items=34 and everything would be mapped to the Users (front module) Model. From there I guess I could just test for the items parameter and retrieve the item #34 for user #324 on a get request.]<=== I just checked it and it doesn't seems to work like that: Acessing /users/234/items/43 and var_dump($this->_getAllParams()); in the get action of the rest controller results in the following output: array(4) { ["controller"]=> string(5) "users" ["action"]=> string(3) "get" [2]=> string(5) "items" ["module"]=> string(7) "default"] } Somehow both ids got lost... Anyone?

  • Query Months help

    - by StealthRT
    Hey all i am in need of some helpful tips/advice on how to go about my problem. I have a database that houses a "signup" table. The date for this table is formated as such: 2010-04-03 00:00:00 Now suppose i have 10 records in this database: 2010-04-03 00:00:00 2010-01-01 00:00:00 2010-06-22 00:00:00 2010-02-08 00:00:00 2010-02-05 00:00:00 2010-03-08 00:00:00 2010-09-29 00:00:00 2010-11-16 00:00:00 2010-04-09 00:00:00 2010-05-21 00:00:00 And i wanted to get each months total registers... so following the example above: Jan = 1 Feb = 2 Mar = 1 Apr = 2 May = 1 Jun = 1 Jul = 0 Aug = 0 Sep = 1 Oct = 0 Nov = 1 Dec = 0 Now how can i use a query to do that but not have to use a query like: WHERE left(date, 7) = '2010-01' and keep doing that 12 times? I would like it to be a single query call and just have it place the months visits into a array like so: do until EOF theMonthArray[0] = "total for jan" theMonthArray[1] = "total for feb" theMonthArray[2] = "total for mar" theMonthArray[3] = "total for apr" ...etc loop I just can not think of a way to do that other than the example i posted with the 12 query called-one for each month. This is my query as of right now. Again, this only populates for one month where i am trying to populate all 12 months all at once. SELECT count(idNumber) as numVisits, theAccount, signUpDate, theActive from userinfo WHERE theActive = 'YES' AND idNumber = '0203' AND theAccount = 'SUB' AND left(signUpDate, 7) = '2010-04' GROUP BY idNumber ORDER BY numVisits; The example query above outputs this: numVisits | theAccount | signUpDate | theActive 2 SUB 2010-04-16 00:00:00 YES Which is correct because i have 2 records within the month of April. But again, i am trying to do all 12 months at one time (in a single query) so i do not tax the database server as much when compared to doing 12 different query's... UPDATE I'm looking to do something like along these lines: if NOT rst.EOF if left(rst("signUpDate"), 7) = "2010-01" then theMonthArray[0] = rst("numVisits") end if if left(rst("signUpDate"), 7) = "2010-02" then theMonthArray[1] = rst("numVisits") end if etc etc.... end if Any help would be great! :) David

  • jquery ui autocomplete problem

    - by Roger
    Hi, i've got a select box containing countries, and when one is selected, i want my autocomplete data for the city field to load via ajax. here's my code: // Sets up the autocompleter depending on the currently // selected country $(document).ready(function() { var cache = getCities(); $('#registration_city_id').autocomplete( { source: cache } ); cache = getCities(); // update the cache array when a different country is selected $("#registration_country_id").change(function() { cache = getCities(); }); }); /** * Gets the cities associated with the currently selected country */ function getCities() { var cityId = $("#registration_country_id :selected").attr('value'); return $.getJSON("/ajax/cities/" + cityId + ".html"); } This returns the following json: ["Aberdare","Aberdeen","Aberystwyth","Abingdon","Accrington","Airdrie","Aldershot","Alfreton","Alloa","Altrincham","Amersham","Andover","Antrim","Arbroath","Ardrossan","Arnold","Ashford","Ashington","Ashton-under-Lyne","Atherton","Aylesbury","Ayr",... ] But, it doesn't work. When i start typing in the city box, the style changes so the autocompleter is doing something, but it won't display this data. If i hard-code the above it works. Can anyone see what's wrong? Thanks

  • What causes exception in string.concat

    - by Budda
    Here are few classes: public class MyItem : ParamOut { public string Code { get { return _quoteCode; } } public InnerItem[] Skus { get { return _skus; } } public PriceSummary Price { get { return _price; } } public override string ToString() { return string.Concat("Code=", Code, "; SKUs=[", Skus != null ?

Question: Q1. what overload of string.Concat will be called in this case? I have 9 parameters, so I guess one of the following: public static string Concat(params Object[] args) or public static string Concat(params string[] values) But which of them? Q2. Why exception is generated? Shouldn't 'null' be converted into something like 'null' or "" (empty string)? Thanks a lot!

  • How do you parse a paragraph of text into sentences? (perferrably in Ruby)

    - by henry74
    How do you take paragraph or large amount of text and break it into sentences (perferably using Ruby) taking into account cases such as Mr. and Dr. and U.S.A? (Assuming you just put the sentences into an array of arrays) UPDATE: One possible solution I thought of involves using a parts-of-speech tagger (POST) and a classifier to determine the end of a sentence: Getting data from Mr. Jones felt the warm sun on his face as he stepped out onto the balcony of his summer home in Italy.

  • fast similarity detection

    - by reinierpost
    I have a large collection of objects and I need to figure out the similarities between them. To be exact: given two objects I can compute their dissimilarity as a number, a metric - higher values mean less similarity and 0 means the objects have identical contents. The cost of computing this number is proportional to the size of the smaller object (each object has a given size). I need the ability to quickly find, given an object, the set of objects similar to it. To be exact: I need to produce a data structure that maps any object o to the set of objects no more dissimilar to o than d, for some dissimilarity value d, such that listing the objects in the set takes no more time than if they were in an array or linked list (and perhaps they actually are). Typically, the set will be very much smaller than the total number of objects, so it is really worthwhile to perform this computation. It's good enough if the data structure assumes a fixed d, but if it works for an arbitrary d, even better. Have you seen this problem before, or something similar to it? What is a good solution? To be exact: a straightforward solution involves computing the dissimilarities between all pairs of objects, but this is slow - O(n2) where n is the number of objects. Is there a general solution with lower complexity?

  • How to get contacts in order of their upcoming birthdays?

    - by Pentium10
    I have code to read contact details and to read birthdays. But how do I get a list of contacts in order of their upcoming birthday? For a single contact identified by id, I get details and birthday like this: Cursor c = null; try { Uri uri = ContentUris.withAppendedId( ContactsContract.Contacts.CONTENT_URI, id); c = ctx.getContentResolver().query(uri, null, null, null, null); if (c != null) { if (c.moveToFirst()) { DatabaseUtils.cursorRowToContentValues(c, data); } } c.close(); // read birthday c = ctx.getContentResolver() .query( Data.CONTENT_URI, new String[] { Event.DATA }, Data.CONTACT_ID + "=" + id + " AND " + Data.MIMETYPE + "= '" + Event.CONTENT_ITEM_TYPE + "' AND " + Event.TYPE + "=" + Event.TYPE_BIRTHDAY, null, Data.DISPLAY_NAME); if (c != null) { try { if (c.moveToFirst()) { this.setBirthday(c.getString(0)); } } finally { c.close(); } } return super.load(id); } catch (Exception e) { Log.v(TAG(), e.getMessage(), e); e.printStackTrace(); return false; } finally { if (c != null) c.close(); } and the code to read all contacts is: public Cursor getList() { // Get the base URI for the People table in the Contacts content // provider. Uri contacts = ContactsContract.Contacts.CONTENT_URI; // Make the query. ContentResolver cr = ctx.getContentResolver(); // Form an array specifying which columns to return. String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME }; Cursor managedCursor = cr.query(contacts, projection, null, null, ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC"); return managedCursor; }

  • Parsing srt subtitles

    - by Vojtech R.
    Hi, I want to parse srt subtitles: 1 00:00:12,815 --> 00:00:14,509 Chlapi, jak to jde s tema pracovníma svetlama?. 2 00:00:14,815 --> 00:00:16,498 Trochu je zesilujeme. 3 00:00:16,934 --> 00:00:17,814 Jo, sleduj. Every item into structure. With this regexs: A: RE_ITEM = re.compile(r'''(?P<index>\d+).(?P<start>\d{2}:\d{2}:\d{2},\d{3}) --> (?P<end>\d{2}:\d{2}:\d{2},\d{3}).(?P<text>.*?)''', re.DOTALL) B: RE_ITEM = re.compile(r'''(?P<index>\d+).(?P<start>\d{2}:\d{2}:\d{2},\d{3}) --> (?P<end>\d{2}:\d{2}:\d{2},\d{3}).(?P<text>.*)''', re.DOTALL) And this code: for i in Subtitles.RE_ITEM.finditer(text): result.append((i.group('index'), i.group('start'), i.group('end'), i.group('text'))) With code B I have only one item in array (because of greedy .*) and with code A I have empty 'text' because of no-greedy .*? How to cure this? Thanks

  • Can't get SWT Display on Mac OS X.

    - by Mattias Holmqvist
    I'm running Mac OS X Snow Leopard and wan't to access the Display from the activator in an OSGi bundle. Below is the start method for my activator: @Override public void start(BundleContext context) throws Exception { ExecutorService service = Executors.newSingleThreadExecutor(); service.execute(new Runnable() { @Override public void run() { Display display = Display.getDefault(); Shell shell = new Shell(display); Text helloText = new Text(shell, SWT.CENTER); helloText.setText("Hello SWT!"); helloText.pack(); shell.pack(); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } }); } Calling this code in a Windows environment works fine, but deploying on Mac OS X I get the following output: 2009-10-14 17:17:54.050 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x101620d20 of class NSCFString autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.081 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x100119240 of class NSCFNumber autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.084 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x1001024b0 of class NSCFString autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.086 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x7fff701d7f70 of class NSCFString autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.087 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x100113330 of class NSCFString autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.092 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x101624540 of class NSCFData autoreleased with no pool in place - just leaking . . . I've used the -XstartOnFirstThread VM argument without any luck. I'm on 64-bit Cocoa but I've also tried 32-bit Cocoa. When trying on Carbon I get the following error: Invalid memory access of location 00000020 eip=9012337c When debugging into the Display class I can see that the Displays[] array only contains null references.

  • How to use BeanTreeView?

    - by joseph
    Hello. I have read through whole platform.netbeans.org and I do not find how to add some instance to existing children. I can add static array of diagrams(created in addNotify()), but how to add new Diagram object to the Children? I want to add it from an action that I will create(not included in code). See the code: public class ExploirerTopComponent extends TopComponent implements ExplorerManager.Provider { ... ... ... public ExploirerTopComponent() { ... ... associateLookup (ExplorerUtils.createLookup(mgr, getActionMap())); mgr.setRootContext(new MyProjects());// setDisplayName ("Projects explorer"); } public class MyProjects extends AbstractNode { public MyProjects(MainProject obj) { super (new ProjectsChildren(), Lookups.singleton(obj)); setDisplayName ( obj.getName()); } public MyProjects() { super (new ProjectsChildren()); setDisplayName ("My projects"); } } . public class ProjectsChildren extends Children.Keys{ public ProjectsChildren() { } @Override protected Node[] createNodes(Object o) { MainProject obj = (MainProject) o; return new Node[] { new MyDiagrams() }; } @Override protected void addNotify() { Diagram[] d = new Diagram[3]; for (int i = 0; i < pr.length; i++) { pr[i] = new Diagram("digram"); } setKeys (pr); } }

  • PHP, MySQL Per row output

    - by Jake
    Been all over the place and spent 8 hours working loops and math...still cant get it... I am writing a CP for a customer. The input form will allow them to add a package deal to their web page. Each package deal is stored in mysql in the following format id header item1 item2 item3...item12 price savings The output is a table with 'header' being the name of the package and each item being 1 of the items in the package stored in a row within the table, then the price and amount saved (all of this is input via a form and INSERT statement by the customer, that part works) stored rows as well. Here is my PHP: include 'dbconnect.php'; $query = "SELECT * FROM md "; $result = mysql_query($query); while ($row = mysql_fetch_array($result)) { //Print 4 tables with header, items, price, savings //Go to next row (on main page) and print 4 more items //Do this until all tables have been printed } mysql_free_result($result); mysql_close($conn); ? Right now the main page is simpley a header div, main div, content wrap and footer div. Ideal HTML output of a 'package' table, not perfect and a little confusing $header $item1 $item2 ect... $price$savings I basically want the PHP to print this 4 times per row on the main page and then move to the next row and print 4 times and continue until there are no more items in the array. So it could be row 1 4 tables, row 2 4 tables, row 3 3 tables. Long, confusing and frustrating. I about to just do 1 item per row..please help Jake
