  • How to check when animation finishes if animation block is

    - by pumpk1n
    I have a controller which adds as subviews a custom UIView class called Circle. Let's call a particular instance of Circle, "circle". I have a method in Circle, animateExpand, which expands the circle by animating the view. In the following code (which lives in the controller) I want to alloc and init a circle, add it to a NSMutableArray circleArray, animate the expansion, and at the end of the expansion, i want to remove the object from the array. My attempt: Circle *circle = [[Circle alloc] init]; [circleArray addObject:circle]; [circle animateExpand]; [circleArray removeObjectIdenticalTo:circle]; [circle release]; The problem is [circleArray removeObjectIdenticalTo:circle]; gets called before the animation finishes. Presumbly because the animation is done on a seperate thread. I cant implement the deletion in completion:^(BOOL finished){ }, because the Circle class does not know about a circleArray. Any solutions would be helpful, thanks!

  • Inserting multiple types into an SQLite database with Python

    - by mankoff
    I'm trying to create an SQLite 3 database from Python. I have a few types I'd like to insert into each record: A float, and then 3 groups of n floats, currently a tuple but could be an array or list.. I'm not well-enough versed in Python to understand all the differences. My problem is the INSERT statement. DAS = 12345 lats = (42,43,44,45) lons = (10,11,12,13) times = (1,2,3,4,5,6,7,8,9) import sqlite3 connection = sqlite3.connect("test.db") cursor = connection.cursor() cursor.execute( "create table foo(DAS LONG PRIMARY KEY,lats real(4),lons real(4), times real(9) )" ) I'm not sure what comes next. Something along the lines of: cmd = 'INSERT into foo values (?,?,?,?), ..." cursor.execute(cmd) How should I best build the SQL insert command given this data?

  • "[object Object]" passed instead of the actual object as parameter

    - by Andrew Latham
    I am using Heroku with a Ruby on Rails application, and running from Safari. I have the following Ajax call: $.ajax({ type : 'POST', url : '/test_page', data : {stuff: arr1}, dataType : 'script' }); arr1 is supposed to be an array of objects. There's a console.log right before that, and it is: [Object, Object, Object, Object, Object, ...] However, I got an error on the server side when I made this ajax call. The logs showed 2012-10-01T03:13:34+00:00 app[web.1]: Parameters: {"stuff"=>"[object Object]"} 2012-10-01T03:13:34+00:00 app[web.1]: WARNING: Can't verify CSRF token authenticity 2012-10-01T03:13:34+00:00 app[web.1]: NoMethodError (undefined method `to_hash' for "[object Object]":String): 2012-10-01T03:13:34+00:00 app[web.1]: Completed 500 Internal Server Error in 1ms I'm unable to replicate the error. It's really confusing to me - what would cause that string to sometimes be passed to the server instead of the object?

  • Rendering a variable with erb.

    - by TZer0
    I've got the following problem: I have rhtml (html minced together with ruby inside <% % and <%= % tags) stored in a database which I want to render. The information is acquired through a query. I need to be able to evaluate the information I get from the database as though as it was normal content inside the .erb-file. What I currently have: <% @mymods.each do |mod| %> <%= render_text(mod["html"])%> <% end %> Where mod["html"] is the variable containing the rhtml-code and @mymods an array of objects from the query. I have currently no idea what function I should use (render_text does, of course, not work). Help is greatly appreciated. /TZer0

  • XSLT: How to escape square brackets in Urls

    - by ilariac
    I have a set of records from Solr where field[@name='url'] can have the following format: http://url/blabla/blabla.aspx?sv=[keyword%20keyword,%201] My understanding is that the square brackets denote an array syntax and I would like to use XSLT to remove the square brackets from all Urls. The reason for this is that I am using an Open URL resolver, which does not currently handle well those characters. The best option would be to strip the square brackets from all URLs before such resources are mediated by the Open URL resolver. There are cases where I have multiple occurrences of square brackets per Url. Can you please help me with this? Thanks for your help, I.

  • Fade between looped background images using jQuery

    - by da5id
    I'm trying to get the background image of a legacy div (by which I mean it already has a background image, which I cannot control & thus have to initially over-write) to smoothly fade between new images indefinitely. Here's what I have so far: var images = [ "/images/home/19041085158.jpg", "/images/home/19041085513.jpg", "/images/home/19041085612.jpg" ]; var counter = 0; setInterval(function() { $(".home_banner").css('backgroundImage', 'url("'+images[counter]+'")'); counter++; if (counter == images.length) { counter = 0; } }, 2000); Trouble is, it's not smooth (I'm aiming for something like the innerfade plugin). EDIT: question originally said "and it's not indefinite (it only runs once through the array).", but Mario corrected my stupid naming error. EDIT2: I'm now using Reigel's answer (see below), which works perfectly, but I still can't find any way to fade between the images smoothly. All help greatfully appreciated :)

  • codeigniter: how to redirect after login to current controller (php_self in regular php)

    - by krike
    Well it's not really a problem but I check if the user exist and log them in and redirect to site/members_area, but I don't want to send the user to a specific page but i want to reload the current controller. So if I login in index/home I would like to be redirected at index/home, how should I proceed? in regular php I would put in the action to redirect to current page <?php echo $_SERVER['PHP_SELF']; ?> This is the code in the framework function validate_credentials() { $this->load->model('membership_model'); $query = $this->membership_model->validate(); if($query) // if the user's credentials validated... { $data = array( 'username' => $this->input->post('username'), 'is_logged_in' => true ); $this->session->set_userdata($data); redirect('site/members_area'); //<-- this line here should be dynamic } else // incorrect username or password { $this->index(); } }

  • Perl Hash Slice, Replication x Operator, and sub params

    - by user210757
    Ok, I understand perl hash slices, and the "x" operator in Perl, but can someone explain the following code example from here (slightly simplified)? sub test{ my %hash; @hash{@_} = (undef) x @_; } Example Call to sub: test('one', 'two', 'three'); This line is what throws me: @hash{@_} = (undef) x @_; It is creating a hash where the keys are the parameters to the sub and initializing to undef, so: %hash: 'one' = undef, 'two' = undef, 'three' = undef The rvalue of the x operator should be a number; how is it that @_ is interpreted as the length of the sub's parameter array? I would expect you'd at least have to do this: @hash{@_} = (undef) x length(@_);

  • Subset sum problem

    - by MadBoy
    I'm having a problem with counting which is continuation of this question. I am not really a math person so it's really hard for me to figure out this subset sum problem which was suggested as resolution. I'm having 4 ArrayList in which I hold data: alId, alTransaction, alNumber, alPrice Type | Transaction | Number | Price 8 | Buy | 95.00000000 | 305.00000000 8 | Buy | 126.00000000 | 305.00000000 8 | Buy | 93.00000000 | 306.00000000 8 | Transfer out | 221.00000000 | 305.00000000 8 | Transfer in | 221.00000000 | 305.00000000 8 | Sell | 93.00000000 | 360.00000000 8 | Sell | 95.00000000 | 360.00000000 8 | Sell | 126.00000000 | 360.00000000 8 | Buy | 276.00000000 | 380.00000000 In the end I'm trying to get what's left for customer and what's left I put into 3 array lists: alNew (corresponds to alNumber), alNewPoIle (corresponds to alPrice), and alNewCo (corrseponds to alID) ArrayList alNew = new ArrayList(); ArrayList alNewPoIle = new ArrayList(); ArrayList alNewCo = new ArrayList(); for (int i = 0; i < alTransaction.Count; i++) { string tempAkcjeCzynnosc = (string) alTransaction[i]; string tempAkcjeInId = (string) alID[i]; decimal varAkcjeCena = (decimal) alPrice[i]; decimal varAkcjeIlosc = (decimal) alNumber[i]; int index; switch (tempAkcjeCzynnosc) { case "Transfer out": case "Sell": index = alNew.IndexOf(varAkcjeIlosc); if (index != -1) { alNew.RemoveAt(index); alNewPoIle.RemoveAt(index); alNewCo.RemoveAt(index); } else { ArrayList alTemp = new ArrayList(); decimal varAkcjeSuma = 0; for (int j = 0; j < alNew.Count; j ++) { string akcjeInId = (string) alNewCo[j]; decimal akcjeCena = (decimal) alNewPoIle[j]; decimal akcjeIlosc = (decimal) alNew[j]; if (tempAkcjeInId == akcjeInId && akcjeCena == varAkcjeCena) { alTemp.Add(j); varAkcjeSuma = varAkcjeSuma + akcjeIlosc; } } if (varAkcjeSuma == varAkcjeIlosc) { for (int j = alTemp.Count -1 ; j >=0 ; j --) { int tempIndex = (int) alTemp[j]; alNew.RemoveAt(tempIndex); alNewPoIle.RemoveAt(tempIndex); alNewCo.RemoveAt(tempIndex); } } } break; case "Transfer In": case "Buy": alNew.Add(varAkcjeIlosc); alNewPoIle.Add(varAkcjeCena); alNewCo.Add(tempAkcjeInId); break; } } Basically I'm adding and removing things from Array depending on Transaction Type, Transaction ID and Numbers. I'm adding numbers to ArrayList like 156, 340 (when it is TransferIn or Buy) etc and then i remove them doing it like 156, 340 (when it's TransferOut, Sell). My solution works for that without a problem. The problem I have is that for some old data employees were entering sum's like 1500 instead of 500+400+100+500. How would I change it so that when there's Sell/TransferOut or Buy/Transfer In and there's no match inside ArrayList it should try to add multiple items from thatArrayList and find elements that combine into aggregate. Inside my code I tried to resolve that problem with simple summing everything when there's no match (index == 1) if (index != -1) { alNew.RemoveAt(index); alNewPoIle.RemoveAt(index); alNewCo.RemoveAt(index); } else { ArrayList alTemp = new ArrayList(); decimal varAkcjeSuma = 0; for (int j = 0; j < alNew.Count; j ++) { string akcjeInId = (string) alNewCo[j]; decimal akcjeCena = (decimal) alNewPoIle[j]; decimal akcjeIlosc = (decimal) alNew[j]; if (tempAkcjeInId == akcjeInId && akcjeCena == varAkcjeCena) { alTemp.Add(j); varAkcjeSuma = varAkcjeSuma + akcjeIlosc; } } if (varAkcjeSuma == varAkcjeIlosc) { for (int j = alTemp.Count -1 ; j >=0 ; j --) { int tempIndex = (int) alTemp[j]; alNew.RemoveAt(tempIndex); alNewPoIle.RemoveAt(tempIndex); alNewCo.RemoveAt(tempIndex); } } But it only works if certain conditions are met, and fails for the rest.

  • Completion block not being called. How to check validity?

    - by HCHogan
    I have this method which takes a block, but that block isn't always called. See the method: - (void)updateWithCompletion:(void (^)(void))completion { [MYObject myMethodWithCompletion:^(NSArray *array, NSError *error) { if (error) { NSLog(@"%s, ERROR not nil", __FUNCTION__); completion(); return; } NSLog(@"%s, calling completion %d", __FUNCTION__, &completion); completion(); NSLog(@"%s, finished completion", __FUNCTION__); }]; } I have some more NSLogs inside completion. Sometimes this program counter just blows right past the call to completion() in the code above. I don't see why this would be as the calling code always passes a literal block of code as input. If you're curious of the output of the line containing the addressof operator, it's always something different, but never 0 or nil. What would cause completion not to be executed?

  • Statement hierarchy in programming languages

    - by sudo
    I quickly wrote an interpreter for some sort of experimental programing language i came up with, in PHP (yes, in PHP). The language itself doesn't have anything really special, I just wanted to give it a try. I got the basic things working (Hello World, input to output, string manipulation, arithmetics) but I'm getting stuck with the management of blocks and grouped statements. What I mean is: PHP and most other languages let you do this: ((2+2)*(8+2)+2), of course not only with mathematical computations. My program structure currently consists of a multidimensional array built like this: ID => Type (Identifier, String, Int, Newline, EOF, Comma, ...) Contents (If identifier, int or string) How could I allow statements to be executed in a defined order like in the PHP example above?

  • Fastest method for SQL Server inserts, updates, selects from C# ASP.Net 2.0+

    - by Ian
    Hi All, long time listener, first time caller. I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

  • How do we know if a query is cache or retrieved from database?

    - by Hadi
    For example: class Product has_many :sales_orders def total_items_deliverable self.sales_orders.each { |so| #sum the total } #give back the value end end class SalesOrder def self.deliverable # return array of sales_orders that are deliverable to customer end end SalesOrder.deliverable #give all sales_orders that are deliverable to customer pa = Product.find(1) pa.sales_orders.deliverable #give all sales_orders whose product_id is 1 and deliverable to customer pa.total_so_deliverable The very point that i'm going to ask is: how many times SalesOrder.deliverable is actually computed, from point 1, 3, and 4, They are computed 3 times that means 3 times access to database so having total_so_deliverable is promoting a fat model, but more database access. Alternatively (in view) i could iterate while displaying the content, so i ends up only accessing the database 2 times instead of 3 times. Any win win solution / best practice to this kind of problem ?

I followed CodeIgnitor's instructions in their "Create a blog in 20 minutes" by storing my database settings in the database.php file; and automatically connecting to the database by inserting "database" in the core array of the autoload.php; and I've added both parent::Controller(); and $this-load-scaffolding('myTableName') to blog's constructor. It still gives me this 404. Any suggestions?
