• Replace existing XML file within iPhone app

  - by Chonch

  Hey, I have an .xml file that is going to be shipped within my app. This file contains values that are read from it and saved as an array when the app launches. Each time the app is run, I want to check with the server if there is an internet connection. If so, I want to get the newest version of the .xml file from the server and replace the one that I currently have saved in my app (this way, the next time the user logs in and doesn't have internet access, he/she will be able to use the old (yet most up to date) data). What is the best way to do this? Thanks,

• How to slow down Uploadify plugin script voor jQuery

  - by Peter

  Now if that isn't a weird question, I don't know what is. But here is the problem: I have a function in my "onSelect" option that has to collect some data (through AJAX) and I have a function in my "onComplete" option that processes the just uploaded files based on the data "onSelect" collected. However, with very small files, the "onSelect" hasn't finished yet before the upload is complete and the "onComplete" fails because it lacks the necessary data. Bigger files work just fine. So, I'm looking for a way to stall the upload of the file. To let it start only after the function in onSelect completed fetching the necessary data. Any ideas? Here is an example of the function that the onSelect triggers: var foo = new Array(); function checkDB( event, queueID , fileObj ) { $.post( ajax_folder + 'fetchData' , { ref: "someValue" } , function( data ){ foo[ queueID ] = data.result; } , 'json' ); return true; }

• Codeigniter: simple form function

  - by Kevin Brown

  I'm stuck writing a simple form...I feel dumb. Here's my controller: function welcome_message(){ //Update welcome message $id = $this->session->userdata('id'); $profile['welcome_message'] = $this->input->post('welcome_message'); $this->db->update('be_user_profiles',$profile, array('user_id' => $id)); } And the html: <?php print form_open('home/welcome_message')?> <input type="checkbox" value="0" checked="false">Don't show me this again</input> <p> <input class="button submit" type="submit" class="close-box" value="Close" /> </p> <?php print form_close()?> Edit I simply need it to submit to a private function and return to the home page (page submitted from).

  - by hfidgen

  Hiya, Can anyone advise me on customising the Add Block form? (/admin/build/block/add) I want to hide the "User specific visibility settings" and "Role specific visibility settings" from users. This is what i've got so far, but obviously it's not right and I can't figure out what the array is.

• How to check image during animation

  - by TomTom

  I have set up an animation in the following way (self is an UIImageView, myImages an Array of UIImages): self.animationImages = myImages; self.animationDuration = 50; self.animationRepeatCount = 0; [self startAnimating]; During the animation I'd like to check the current image. I tried it the following way if([self image]==[UIImage imageNamed:@"image1.png"]); but this does not work. Is there a straight forward way for this? Can I keep track of which image is shown during the animation?

  - by karthik

  we tried to give our tables(users,messages) like this in two different abstract classes but it is not working. This is included in a file childconnect1.php ,is there any relation between the file name(childconnect1.php) and the class(Application_Model_childconnect1). class Application_Model_childconnect1 extends Zend_Db_Table_Abstract { protected $_name = 'users'; public function loginvalidation($username,$pwd) { $row = $this->fetchRow('UserName = \'' . $username .

• Retain Delimiters when Splitting String

  - by JoeC

  Edit: OK, I can't read, thanks to Col. Shrapnel for the help. If anyone comes here looking for the same thing to be answered... print_r(preg_split('/([\!|\?|\.|\!\?])/', $string, null, PREG_SPLIT_DELIM_CAPTURE)); Is there any way to split a string on a set of delimiters, and retain the position and character(s) of the delimiter after the split? For example, using delimiters of ! ? . !? turning this: $string = 'Hello. A question? How strange! Maybe even surreal!? Who knows.'; into this array('Hello', '.', 'A question', '?', 'How strange', '!', 'Maybe even surreal', '!?', 'Who knows', '.'); Currently I'm trying to use print_r(preg_split('/([\!|\?|\.|\!\?])/', $string)); to capture the delimiters as a subpattern, but I'm not having much luck.

• Where should I define custom routes in my ZF 1.10 app?

  - by Ross

  With the new Zend_Application/Zend_Application_Bootstrap classes I'm confused as to where I should be applying my custom routes. For example, at the moment I have one route: protected function _initRouter() { $router = new Zend_Controller_Router_Rewrite; $route = new Zend_Controller_Router_Route('news/:id', array('controller' => 'news', 'action' => 'view')); $router->addRoute('postArchive', $route); } This method is in my Zend_Application_Bootstrap_Bootstrap and is definitely run. The route is also applied in $router. As I see it I could be doing two things wrong - either the wrong place to add these routes, or not adding to the correct router. Can anyone point me in the right direction with this?

• JButtons re-enable themselves after being disabled

  - by Anarchist

  I have an array of JButtons which form a keypad interface. After six numbers are entered I want to disable the keypad so that no further numbers can be entered by the user. I have written the code and the buttons do disable until the mouse hovers above any of them, then the buttons seem to re-enable themselves and run actionEvents added to them. The full code is available here. Possible things that I think are wrong. There is some sort of MouseListener which is ignoring when I set button.setEnabled(false); I haven't separated attributes from the buildGUI(); correctly, I only did this anyway so that the inner class could access them. Possibly something to do with the gridLayout as disabling the buttons seems to work for my services JPanel buttons.

• sfConfig::get is not returning constants defined in app.yml

  - by morpheous

  I have an interesting problem. I am using Symfony 1.3.2. I have defined some constants in project/apps/frontend/config/app.yml and project/config/app.yml When I use the constant (correct spelling) in a piece of code like this $test=sfConfig::get('app_foobar'); the variable $test is assigned a null value. This is what I have checked so far: CHECK: cache files generated? (YES) CHECK: Do the cache files (config_app.yml.php) in the cache directory contain the constants defined in the app.yml file (YES) CHECK: Constant names used in the code matches the array keys found in config_app.yml? (YES) At this stage, I have run out of ideas. I dont want to supply a default value as a hack, because when I need to change the value of the constant, I will have to replace this in potentially hundreds of instances (too error prone). Is there anything that I have missed?. What could be causing this?

• NSMutableArray in appdelegate - EXEC_BAD_ACCESS

  - by Tejaswi Yerukalapudi

  Hi, I'm trying to use a global array in the appdelegate as a quick fix for a demo I'm building. The relevant code for this .h file has the declaration { NSMutableArray *trnEntered; } @property (nonatomic, retain) NSMutableArray *trnEntered .m file has the following code - trnEntered = [[NSMutableArray alloc] init]; NSLog(@"%@",[trnEntered count]); // prints null. [trnEntered addObject:@"1"]; NSLog(@"%@",[trnEntered count]); // exec bad access. Not sure where I'm going wrong here. Looks fairly straight forward. Thanks for the help in advance, Teja.

• Using typedefs (or #defines) on built in types - any sensible reason?

  - by jb

  Well I'm doing some Java - C integration, and throught C library werid type mappings are used (theres more of them;)): #define CHAR char /* 8 bit signed int */ #define SHORT short /* 16 bit signed int */ #define INT int /* "natural" length signed int */ #define LONG long /* 32 bit signed int */ typedef unsigned char BYTE; /* 8 bit unsigned int */ typedef unsigned char UCHAR; /* 8 bit unsigned int */ typedef unsigned short USHORT; /* 16 bit unsigned int */ typedef unsigned int UINT; /* "natural" length unsigned int*/ Is there any legitimate reason not to use them? It's not like char is going to be redefined anytime soon. I can think of: Writing platform/compiler portable code (size of type is underspecified in C/C++) Saving space and time on embedded systems - if you loop over array shorter than 255 on 8bit microprocessor writing: for(uint8_t ii = 0; ii < len; ii++) will give meaureable speedup.

• Simplest way to extend doctrine for MVC Models

  - by RobertPitt

  Im developing my own framework that uses namespaces. Doctrine is already integrated into my auto loading system and im now at the stage where ill be creating the model system for my application Usually i would create a simple model like so: namespace Application\Models; class Users extends \Framework\Models\Database{} which would inherit all the default database model methods, But with Doctrine im still learning how it all works, as its not just a simple DBAL. I need to understand whats the part of doctrine my classes would extend where i can do the following: namespace Application\Models; class Users Extends Doctrine\Something\Table { public $__table_name = "users"; } And thus within the controller i would be able to do the following: public function Display($uid) { $User = $this->Model->Users->findOne(array("id" => (int)$id)); } Anyone help me get my head around this ?

• Flexible Data source for Multi-Section Table View Controller

  - by TuanCM

  I have a TableViewController which display a list of NewsItem objects: @interface NewsItem : NSObject { NSString *feedID; NSString *title; NSDate *published; } I'm trying to implement a Table View Controller (multiple sections) that can display the list in two ways: One divide News Items into sections which based on Published Date The other would be based on FeedID (News source). And I don't know how to structure the data source so that the code is easy to maintain. I tried to put the list of News Items into a 2 dimension Array in this case is a NSMutableArray of NSArray objects. However I got some objc_exception_throw and I don't think this is flexible enough. Could you guys give me some ideas?

• How to batch retrieve documents with mongoDB?

  - by edude05

  Hello everyone, I have an application that queries data from a mongoDB using the mongoDB C# driver something like this: public void main() { foreach (int i in listOfKey) { list.add(getObjectfromDB(i); } } public myObject getObjFromDb(int primaryKey) { document query = new document(); query["primKey"] = primaryKey; document result= mongo["myDatabase"]["myCollection"].findOne(query); return parseObject(result); } On my local (development) machine to get 100 object this way takes less than a second. However, I recently moved the database to a server on the internet, and this query takes about 30 seconds to execute for the same number of object. Furthermore, looking at the mongoDB log, it seems to open about 8-10 connections to the DB to perform this query. So what I'd like to do is have the query the database for an array of primaryKeys and get them all back at once, then do the parsing in a loop afterwards, using one connection if possible. How could I optimize my query to do so? Thanks, --Michael

• How to perform an external request in Kohana 3?

  - by alex

  I've always used cURL for this sort of stuff, but this article got me thinking I could request another page easily using the Request object in Kohana 3. $url = 'http://www.example.com'; $update = Request::factory($url); $update->method = 'POST'; $update->post = array( 'key' => 'value' ); $update->execute(); echo $update->response; However I get the error Accessing static property Request::$method as non static From this I can assume it means that the method method is static, but that doesn't help me much. I also copied and pasted the example from that article and it threw the same error. Basically, I'm trying to POST to a new page on an external server, and do it the Kohana way. So, am I doing this correctly, or should I just use cURL (or file_get_contents() with context)?

• C++ function-pointer and inheritance

  - by pingvinus

  In parent class I have function, that operates under an array of functions, declared in child-class, number of functions for every child-class may vary. But since every function uses some object-variables, I can't declare them as static. I've try to do something like this: class A { public: typedef int (A::*func)(); func * fs; void f() { /*call functions from this->fs*/ } }; class B : public A { public: int smth; B(int smth) { this->smth = smth; this->fs = new func[1]; fs[0] = &B::f; } int f() { return smth + 1; } }; But, obviously it doesn't work. Any suggestions?

• C++ USB Programming

  - by JB_SO

  Hi, I am new to hardware programming(especially USB) so please bear with me and my questions. I am using C++ and I need to send/receive some data (a byte array) to/from a USB port on a microprocessor board. Now, I have done some serial port programming before and I know that for a serial port you have to open a port, setup, perform i/o and finally close the port. I am guessing to use a USB port, it is not as simple as what I mentioned above. I do know that I want to use Microsoft standard drivers and implement standard Windows IO commands to accomplish this, since I believe there are no drivers for the microprocessor board for me to interact with. If somebody can point me in the right direction as to the steps needed to "talk" to a USB port (open, setup, i/o) via standard Windows IO commands, I would truly and greatly appreciate it. Thanks you so much!!

• Rails: Design Pattern to Store Order of Relations

  - by ChrisInCambo

  Hi, I have four models: Customer, QueueRed, QueueBlue, QueueGreen. The Queue models have a one to many relationship with customers A customer must always be in a queue A customer can only be in one queue at a time A customer can change queues We must be able to find out the customers current position in their respective queue In an object model the queues would just have an array property containing customers, but ActiveRecord doesn't have arrays. In a DB I would probably create some extra tables just to handle the order of the stories in the queue. My question is what it the best way to model the relationship in ActiveRecord? Obviously there are many ways this could be done, but what is the best or the most in line with how ActiveRecord should be used? Cheers, Chris

• Implementing a runtime Look Up Table in C#

  - by Yarok

  Hey all, I'm currently working on a robot interface GUI, using C#. The robot has two sensors, and two powered wheels. I need to let the user the option to load a Look Up Table (LUT) during runtime, one for each sensor, that will tell the robot what to do according to the sensor's reading. I think the best way to do it is using a .csv file, formatted like so: index , right wheel order, left wheel order the index is an int between 0-1023 and is actually the sensor's reading. the orders for the right and left wheel are integers, between -500 - 500. Example - left sensor's readings: 1,10,20 meaning: sensor reads 1 -- left wheel 10 rpm right wheel 20 rpm So my question is this: what is the best way to implement it? using a dataset?(if so, how?) using an array? (if so, how do I load it during runtime?) Any help would be much appreciated, Yarok

• Generating a beveled edge for a 2D polygon

  - by Metaphile

  I'm trying to programmatically generate beveled edges for geometric polygons. For example, given an array of 4 vertices defining a square, I want to generate something like this. But computing the vertices of the inner shape is baffling me. Simply creating a copy of the original shape and then scaling it down will not produce the desired result most of the time. My algorithm so far involves analyzing adjacent edges (triples of vertices; e.g., the bottom-left, top-left, and top-right vertices of a square). From there, I need to find the angle between them, and then create a vertex somewhere along that angle, depending on how deep I want the bevel to be. And because I don't have much of a math background, that's where I'm stuck. How do I find that center angle? Or is there a much simpler way of attacking this problem?
