• how to insert page view of a node in another page in drupal

  - by sprugman

  I have a list of node ids and I want to display the 'page' view of each one. For various reasons, I don't want to do this with views, and don't think I should need a module. Just an API call to theme('node'). Something like: $nids = array(3,4,5); foreach ($nids as $nid) { $node = node_load($nid); $result .= theme('node', $node); } but I'm not getting back the full page view of the node. I added this to my node-[type].tpl.php file: if ($page) print "PAGE MODE "; else print "NOT PAGE "; if ($teaser) print "TEASER MODE "; else print "NOT TEASER "; and got: NOT PAGE NOT TEASER I seem to be in some kind of limbo. I suspect there's an argument that I add to the theme function, but the terms are all so general (theme, teaser, page, node), I'm having trouble with my google-fu.

• AS3 try/catch out of memory

  - by StfnoPad

  Hi, I'm loading a few huge images on my flex/as3 app, but I can't manage to catch the error when the flash player runs out of memory. Here is the what I was thinking might work (I use ???? because i dont know what to catch): try{ images = new Array(frames); for (var i:uint = 0; i < frames; i++){ imagesBA[i] = new BitmapData(width, height, false, 0x000000FF); } } catch(error:????){ Alert.show("Out of memory!"); } Any idea what ???? can be? Or does anyone knows how to catch when there is no memory for a variable?

• 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

• Passing a web service an unknown number of parameters

  - by Billyhole

  I'm relatively new to utilizing web services. I'm trying to create one that will be accepting data from a ASP.Net form whose input controls are created dynamically at runtime and I don't how many control values will be getting passed. I'm thinking I'll be using jQuery's serialize() on the form to get the data, but what do I have the web service accept for a parameter? I thought maybe I could use serializeArray(), but still I don't know what type of variable to accept for the JavaScript array. Finally, I was thinking that I might need to create a simple data transfer object with the data before sending it along to the web service. I just didn't wanna go through with the DTO route if there was a much simpler way or an established best practice that I should follow. Thanks in advance for any direction you can provide and let me know I wasn't clear enough, or if you have any questions.

• C# UDP Socket taking time to send data to unknown IP

  - by Mohsan

  Hi. i am sending data to UDP socket using this code Socket udpClient = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Parse(obj.destAddress), obj.destPort); byte[] buf = new byte[obj.length]; Array.Copy((byte[])obj.data, buf, obj.length); int n = udpClient.SendTo(buf, ipEndPoint); udpClient.Close(); this code works fine when IP exists in current network, but it takes 3-5 seconds when I send data to unknown IP address. This causes main application to hang for 3-5 seconds.. What could be the reason behind this problem..

• 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)?

• 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 ?

• CakePHP hasAndBelongsToMany (HABTM) Delete Joining Record

  - by Jason McCreary

  I have a HABTM relationship between Users and Locations. Both Models have the appropriate $hasAndBelongsToMany variable set. When I managing User Locations, I want to delete the association between the User and Location, but not the Location. Clearly this Location could belong to other users. I would expect the following code to delete just the join table record provided the HABTM associations, but it deleted both records. $this->Weather->deleteAll(array('Weather.id' => $this->data['weather_ids'], false); However, I am new to CakePHP, so I am sure I am missing something. I have tried setting cascade to false and changing the Model order with User, User-Weather, Weather-User. No luck. Thanks in advance for any help.

• Determining the number of objects in an NSArray

  - by Viral

  Hi friends, I am making a book application. To move to the next topic I am using a button. The Button works as it moves to the next topic, but at the end of the file my application gets the message obj_fatal and it crashes. If I knew how many objects there are in my NSArray then the problem will be solved. I am getting the details from a .plist file and storing it in to a array. So if any one knows how, please let me know. Thanks in advance. Viral.

I have yet to find anything in the Book or by search. So any help is appreciated. Thanks.

• 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.

• How to perform a join with CodeIgniter's Active Record class on a multicolumn key?

  - by Scott Southworth

  I've been able to make this code work using CodeIgniter's db->query as follows: $sql = 'SELECT mapping_code,zone_name,installation_name FROM installations,appearances,zones WHERE installations.installation_id = zones.installation_fk_id AND appearances.installation_fk_id = installations.installation_id AND appearances.zone_fk_id = zones.zone_id AND appearances.barcode = ? '; return $this->db->query($sql,array($barcode)); The 'appearances' table throws a 'not unique table' error if I try this using the Active Record class. I need to join appearances on both the zone and installations tables. How can I do this?

• what are the recent dataStructure and algorithms that one should know?

  - by Shamik

  Recently I came across the SkipList data structure. It really helped me to solve one otherwise critical problem to be solved. I was struggling to solve the same problem with Balanced Binary tree but it became very complex as the tree needs to be always balanced and I wanted to know the existence of not only a particular value but values in certain range. SkipList helped me to solve that problem effectively. I am wondering what else data structures that I need to know? I know - Array, List, Stack, Queue, Linked List, hashtable, tree and its different forms like B-tree, Trie etc. Would like to know if you find some other data structure/concept very interesting to know yet effective enough to be used in a daily development cycle.

• 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?

  Hi I have a table view, and when I delete a cell I am removing an item from an NSMutableArray, archiving that array, and removing the cell. However, when I do this, it is causing the delete button to lag after I click it. Is there any way to fix this? // Override to support editing the table view. - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { int row = [indexPath row]; [savedGames removeObjectAtIndex:row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; //this line causing lag [NSKeyedArchiver archiveRootObject:savedGames toFile:[self dataFilePath]]; } } Thanks

• Generic TypeIdenitifier convertion.How?

  - by John

  How do I convert the TypeIdenitifier to a class type? I need to use implicit convertion. type TMyChildArray<T>=class(TMyArray<T>) private FData:Array of T; procedure AddEnd(); end; TTypeIdenitifierParentClass=class(TAnotherParentClass) protected TestField:Cardinal; end; procedure TMyChildArray<T>.AddEnd(); var elem:T; begin for elem in Fdata do TTypeIdenitifierParentClass(elem).TestField:=0; end; I get "Invalid typecast" on the implicit convertion "TTypeIdenitifierParentClass(elem).TestField:=0;". The principle I want to use is that the TypeIdenitifier will represent a class that descends from TTypeIdenitifierParentClass.There are many class types,but all of them descend that class. How do I do this?

• How to repopulate DataTables when having lots of data?

  - by chobo2

  Hi I am using datatables jquery plugin. I now have to clear the entire datatable and populate it with new data on the fly(all done through ajax). So what I was thinking to do is when I need to do this. Destroy the datatable remove the data html call up the partial view that renders the table Rebind the datatable with jquery. However it seems that datatable has no destroy method. So I know you can set the datatable to do something with ajax but I am not sure how. My datatable just uses the dom way when the page is loaded. I don't want to use the "fnAddData" as I am not sure how to format this 2d array they want and I don't think this is the best option. I think the best option is some how render the partial view back and use there ajax plugin. But I am not sure where that is or how to use it(I know it exists but that's about it). Thanks

• 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!!

• What is the best way to organize Java code since you can't pass by reference?

  - by Adam

  I'm learning how to code in Java after after coming from C. In C I always separated everything into individual functions to make the code easier to follow and edit. I was trying to do this in java but now since I realized that you can't use pointers, I am a bit confused as to what the best way to do this is. So for example I want to have a method that creates four alerts for me. So I pass it an alert builder that can then create the alerts. I can return them in an array, but in my code I already have the alerts individually named, and I would like to keep it that way so I wouldn't need to refer to them as alert[1], alert[2]... etc. So that means I would have to rename them, which would add additional code which would probably be longer than the code in the actual method! Am I thinking about this the right way? Is there anything I can do?
