• How can I interrupt a ServerSocket accept() method?

  - by lukeo05

  Hi, In my main thread I have a while(listening) loop which calls accept() on my ServerSocket object, then starts a new client thread and adds it to a Collection when a new client is accepted. I also have an Admin thread which I want to use to issue commands, like 'exit', which will cause all the client threads to be shut down, shut itself down, and shut down the main thread, by turning listening to false. However, the accept() call in the while(listening) loop blocks, and there doesn't seem to be any way to interrupt it, so the while condition cannot be checked again and the program cannot exit! Is there a better way to do this? Or some way to interrupt the blocking method? Thanks!

• Problem of reading OWL/XML

  - by Mikae Combarado

  Hello, I have a problem reading OWL/XML files from Java using Jena. I have no problem reading RDF/XML files, but whenever I create a OWL/XML file from Protege and try to read it, Java gives this error below : WARN [main] (RDFDefaultErrorHandler.java:36) Exception in thread "main" java.lang.NullPointerException at com.hp.hpl.jena.rdf.arp.impl.XMLHandler.endElement(XMLHandler.java:143) The code that I use to retrieve RDF/XML is below : OntModel ontModel = ModelFactory.createOntologyModel(); InputStream in = FileManager.get().open(inputFileName); if (in == null) { throw new IllegalArgumentException( "File: " + inputFileName + " not found"); } ontModel.read(in, ""); This code works with RDF/XML perfectly. However, I cannot read an OWL/XML. I looked at Internet and I couldn't find anything. I would really appreciate, if someone shows me a way. Many thanks

• Algorithmic trading software safety guards

  - by Adal

  I'm working on an automatic trading system. What sorts of safe-guards should I have in place? The main idea I have is to have multiple pieces checking each other. I will have a second independent little process which will also connect to the same trading account and monitor simple things, like ensuring the total net position does not go over a certain limit, or that there are no more than N orders in 10 minutes for example, or more than M positions open simultaneously. You can also check that the actual open positions correspond to what the strategy process thinks it actually holds. As a bonus I could run this checker process on a different machine/network provider. Besides the checks in the main strategy, this will ensure that whatever weird bug occurs, nothing really bad can happen. Any other things I should monitor and be aware of?

• php cpanel

  - by Miguel Ping

  I have a php account with my provider, and I also have cpanel installed for me. I currently have two drupal sites there, let's called the main myMainSite and another one under construction called myNewSite. So when I go to www.myMainSite.com, I go to the main site. When I go to myNewSite.myMainSite.com, i go to the drupal site that is under construction. My question is, when my under construction site goes live, I want that all users that go to www.myMainSite.com see the new site (the one that is under myNewSite.myMainSite.com). How can I accomplish this with cpanel? is it within the "addon domains" configuration? I don't want a redirect that changes the address bar, ie, I want to keep the original url.

• How to change the band height dynamically?

  - by Kumar

  Is it possible to modify the height of detail band dynamically in jasper report? Because in my application i need to create pdf document.I have used one main document inside detail band of that main document i used one subreport. Sub report will take java bean as data source. This java bean return a list of field. So if we fixed the size of band then some time all values are not stretch in the document. Is it possible to change the detail band dynamically.

• Needing forward declaration in Ruby

  - by dbarbosa

  Hi, I am trying to write a Ruby script in one file. I would like to know if it is possible to write the "main" function in the beginning, having the other functions that are used by main, defined after it. In other words, I would like to call a not yet defined function, so that they do not depends on definition order. Just changing the order is not possible because it gives an "undefined method" error. In C/C++ we use forward declarations... is there something similar in Ruby or another solution to this?

• How do I get the value of a DynamicControl?

  - by Telos

  I'm using ASP.NET Dynamic Data functionality to do something a little weird. Namely, create a dynamic list of fields as children of the main object. So basically I have Ticket.Fields. The main page lists all the fields for Ticket, and the Fields property has a DynamicControl that generates a list of controls to collect more data. The tricky part is that this list ALSO uses Dynamic Data to generate the controls, so each field can be any of the defined FieldTemplates... meaning I don't necessarily know what the actual data control will be when I try to get the value. So, how do I get the value of a DynamicControl? Do I need to create a new subclass of FieldTemplate that provides a means to get at the value?

• Usage of closures with multiple arguments in swift

  - by Nilzone-

  This question is largely based on this one: Link The main difference being that I want to pass in arguments to the closure as well. Say I have something like this: func someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> ()) { // function body goes here var error: NSError? let responseDictionary: Dictionary<String, AnyObject> = ["test" : "test2"] completionClosure(venues: responseDictionary, error: error!) } No error here. But when I call this function in my main view controller I have tried several ways but all of the result in different errors: venueService.someFunctionThatTakesAClosure(completionClosure(venues: Dictionary<String, AnyObject>, error: NSError){ }) or like this: venueService.someFunctionThatTakesAClosure((venues: Dictionary<String, AnyObject>, error: NSError){ }) or even like this: venueService.someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> (){ }); I'm probably just way tired, but any help would be greatly appreciated!

• Two '==' equality operators in same 'if' condition are not working as intended.

  - by Manav MN

  I am trying to establish equality of three equal variables, but the following code is not printing the obvious true answer which it should print. Can someone explain, how the compiler is parsing the given if condition internally? #include<stdio.h> int main() { int i = 123, j = 123, k = 123; if ( i == j == k) printf("Equal\n"); else printf("NOT Equal\n"); return 0; } Output: manav@workstation:~$ gcc -Wall -pedantic calc.c calc.c: In function ‘main’: calc.c:5: warning: suggest parentheses around comparison in operand of ‘==’ manav@workstation:~$ ./a.out NOT Equal manav@workstation:~$ EDIT: Going by the answers given below, is the following statement okay to check above equality? if ( (i==j) == (j==k))

• log4j performance

  - by Bob

  Hi, I'm developing a web app, and I'd like to log some information to help me improve and observe the app. (I'm using Tomcat6) First I thought I would use StringBuilders, append the logs to them and a task would persist them into the database like every 2 minutes. Because I was worried about the out-of-the-box logging system's performance. Then I made some test. Especially with log4j. Here is my code: Main.java public static void main(String[] args) { Thread[] threads = new Thread[LoggerThread.threadsNumber]; for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i] = new Thread(new LoggerThread("name - " + i)); } LoggerThread.startTimestamp = System.currentTimeMillis(); for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i].start(); } LoggerThread.java public class LoggerThread implements Runnable{ public static int threadsNumber = 10; public static long startTimestamp; private static int counter = 0; private String name; public LoggerThread(String name) { this.name = name; } private Logger log = Logger.getLogger(this.getClass()); @Override public void run() { for(int i=0; i<10000; ++i){ log.info(name + ": " + i); if(i == 9999){ int c = increaseCounter(); if(c == threadsNumber){ System.out.println("Elapsed time: " + (System.currentTimeMillis() - startTimestamp)); } } } } private synchronized int increaseCounter(){ return ++counter; } } } log4j.properties log4j.logger.main.LoggerThread=debug, f log4j.appender.f=org.apache.log4j.RollingFileAppender log4j.appender.f.layout=org.apache.log4j.PatternLayout log4j.appender.f.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.appender.f.File=c:/logs/logging.log log4j.appender.f.MaxFileSize=15000KB log4j.appender.f.MaxBackupIndex=50 I think this is a very common configuration for log4j. First I used log4j 1.2.14 then I realized there was a newer version, so I switched to 1.2.16 Here are the figures (all in millisec) LoggerThread.threadsNumber = 10 1.2.14: 4235, 4267, 4328, 4282 1.2.16: 2780, 2781, 2797, 2781 LoggerThread.threadsNumber = 100 1.2.14: 41312, 41014, 42251 1.2.16: 25606, 25729, 25922 I think this is very fast. Don't forget that: in every cycle the run method not just log into the file, it has to concatenate strings (name + ": " + i), and check an if test (i == 9999). When threadsNumber is 10, there are 100.000 loggings and if tests and concatenations. When it is 100, there are 1.000.000 loggings and if tests and concatenations. (I've read somewhere JVM uses StringBuilder's append for concatenation, not simple concatenation). Did I missed something? Am I doing something wrong? Did I forget any factor that could decrease the performance? If these figures are correct I think, I don't have to worry about log4j's performance even if I heavily log, do I?

• Reading a file with a supplied name in C++

  - by Cosmina

  I must read a file with a given name (it's caled "hamlet.txt"). The class used to read the file is defined like this #ifndef READWORDS_H #define READWORDS_H /** * ReadWords class. Provides mechanisms to read a text file, and return * capitalized words from that file. */ using namespace std; #include <string> #include <fstream> class ReadWords { public: /** * Constructor.

Opens the file with the given filename. * Program exits with an error message if the file does not exist. * @param filename - a C string naming the file to read. */ ReadWords(char *filename); My definition of the members of the classis this: #include<string> #include<fstream> #include<iostream> #include "ReadWords.h" using namespace std; ReadWords::ReadWords() { wordfile.open("text.txt"); if( !wordfile ) { cout<<"Errors while opening the file!"<<endl; } } ReadWords::ReadWords(char *filename) { wordfile.open(filename); if ( !wordfile ) { cout<<"Errors while opening the file!"<<endl; } wordfile>>nextword; } And the main to test it. using namespace std; #include #include #include "ReadWords.h" int main() { char name[30]; cout<<"Please input a name for the file that you wish to open"; cin>>name; ReadWords x( name[] ); } When I complie it gives me the error: main.cpp:14: error: expected primary-expression before ']' token I know it's got something to do with the function ReadWords( char *filename), but I do not know what. Any help please?

• Multiple actions upon a case statement in Haskell

  - by Schroedinger

  One last question for the evening, I'm building the main input function of my Haskell program and I have to check for the args that are brought in so I use args <- getArgs case length args of 0 -> putStrLn "No Arguments, exiting" otherwise -> { other methods here} Is there an intelligent way of setting up other methods, or is it in my best interest to write a function that the other case is thrown to within the main? Or is there an even better solution to the issue of cases. I've just got to take in one name.

• Qt - problem appending to QList of QList

  - by bullettime

  I'm trying to append items to a QList at runtime, but I'm running on a error message. Basically what I'm trying to do is to make a QList of QLists and add a few customClass objects to each of the inner lists. Here's my code: widget.h: class Widget : public QWidget { Q_OBJECT public: Widget(QWidget *parent = 0); ~Widget(); public slots: static QList<QList<customClass> > testlist(){ QList<QList<customClass> > mylist; for(int w=0 ; w<5 ; w++){ mylist.append(QList<customClass>()); } for(int z=0 ; z<mylist.size() ; z++){ for(int x=0 ; x<10 ; x++){ customClass co = customClass(); mylist.at(z).append(co); } } return mylist; } }; customclass.h: class customClass { public: customClass(){ this->varInt = 1; this->varQString = "hello world"; } int varInt; QString varQString; }; main.cpp: int main(int argc, char *argv[]) { QApplication a(argc, argv); Widget w; QList<QList<customClass> > list; list = w.testlist(); w.show(); return a.exec(); } But when I try to run the application, it gives off this error: error: passing `const QList<customClass>' as `this' argument of `void List<T>::append(const T&) [with T = customClass]' discards qualifiers I also tried inserting the objects using foreach: foreach(QList<customClass> list, mylist){ for(int x=0 ; x<10 ; x++){ list.append(customClass()); } } The error was gone, but the customClass objects weren't appended, I could verify that by using a debugging loop in main that showed the inner QLists sizes as zero. What am I doing wrong?

• Logic differences in C and Java

  Compile and run this code in C #include <stdio.h> int main() { int a[] = {10, 20, 30, 40, 50}; int index = 2; int i; a[index++] = index = index + 2; for(i = 0; i <= 4; i++) printf("%d\n", a[i]); } Output : 10 20 4 40 50 Now for the same logic in Java class Check { public static void main(String[] ar) { int a[] = {10, 20, 30, 40, 50}; int index = 2; a[index++] = index = index + 2; for(int i = 0; i <= 4; i++) System.out.println(a[i]); } } Output : 10 20 5 40 50 Why is there output difference in both languages, output is understandable for Java but I cannot understand output in C One more thing, if we apply the prefix ++ operator, we get the same result in both languages, why?

• C# problem with two threads and hardware access

  - by mack369

  I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

• php split array into smaller even arrays

  I have a function that is supposed to split my array into smaller, evenly distributed arrays, however it seems to be duplicating my data along the way. If anyone can help me out that'd be great. Here's the original array: Array ( [0] => stdClass Object ( [bid] => 42 [name] => Ray White Mordialloc [imageurl] => sp_raywhite.gif [clickurl] => http://www.raywhite.com/ ) [1] => stdClass Object ( [bid] => 48 [name] => Beachside Osteo [imageurl] => sp_beachside.gif [clickurl] => http://www.beachsideosteo.com.au/ ) [2] => stdClass Object ( [bid] => 53 [name] => Carmotive [imageurl] => sp_carmotive.jpg [clickurl] => http://www.carmotive.com.au/ ) [3] => stdClass Object ( [bid] => 51 [name] => Richmond and Bennison [imageurl] => sp_richmond.jpg [clickurl] => http://www.richbenn.com.au/ ) [4] => stdClass Object ( [bid] => 50 [name] => Letec [imageurl] => sp_letec.jpg [clickurl] => www.letec.biz ) [5] => stdClass Object ( [bid] => 39 [name] => Main Street Mordialloc [imageurl] => main street cafe.jpg [clickurl] => ) [6] => stdClass Object ( [bid] => 40 [name] => Ripponlea Mitsubishi [imageurl] => sp_mitsubishi.gif [clickurl] => ) [7] => stdClass Object ( [bid] => 34 [name] => Adrianos Pizza & Pasta [imageurl] => sp_adrian.gif [clickurl] => ) [8] => stdClass Object ( [bid] => 59 [name] => Pure Sport [imageurl] => sp_psport.jpg [clickurl] => http://www.puresport.com.au/ ) [9] => stdClass Object ( [bid] => 33 [name] => Two Brothers [imageurl] => sp_2brothers.gif [clickurl] => http://www.2brothers.com.au/ ) [10] => stdClass Object ( [bid] => 52 [name] => Mordialloc Travel and Cruise [imageurl] => sp_morditravel.jpg [clickurl] => http://www.yellowpages.com.au/vic/mordialloc/mordialloc-travel-cruise-13492525-listing.html ) [11] => stdClass Object ( [bid] => 57 [name] => Southern Suburbs Physiotherapy Centre [imageurl] => sp_sspc.jpg [clickurl] => http://www.sspc.com.au ) [12] => stdClass Object ( [bid] => 54 [name] => PPM Builders [imageurl] => sp_ppm.jpg [clickurl] => http://www.hotfrog.com.au/Companies/P-P-M-Builders ) [13] => stdClass Object ( [bid] => 36 [name] => Big River [imageurl] => sp_bigriver.gif [clickurl] => ) [14] => stdClass Object ( [bid] => 35 [name] => Bendigo Bank Parkdale / Mentone East [imageurl] => sp_bendigo.gif [clickurl] => http://www.bendigobank.com.au ) [15] => stdClass Object ( [bid] => 56 [name] => Logical Services [imageurl] => sp_logical.jpg [clickurl] => ) [16] => stdClass Object ( [bid] => 58 [name] => Dicount Lollie Shop [imageurl] => new dls logo.jpg [clickurl] => ) [17] => stdClass Object ( [bid] => 46 [name] => Patterson Securities [imageurl] => cmyk patersons_withtag.jpg [clickurl] => ) [18] => stdClass Object ( [bid] => 44 [name] => Mordialloc Personal Trainers [imageurl] => sp_mordipt.gif [clickurl] => # ) [19] => stdClass Object ( [bid] => 37 [name] => Mordialloc Cellar Door [imageurl] => sp_cellardoor.gif [clickurl] => ) [20] => stdClass Object ( [bid] => 41 [name] => Print House Graphics [imageurl] => sp_printhouse.gif [clickurl] => ) [21] => stdClass Object ( [bid] => 55 [name] => 360South [imageurl] => sp_360.jpg [clickurl] => ) [22] => stdClass Object ( [bid] => 43 [name] => Systema [imageurl] => sp_systema.gif [clickurl] => ) [23] => stdClass Object ( [bid] => 38 [name] => Lowe Financial Group [imageurl] => sp_lowe.gif [clickurl] => http://lowefinancial.com/ ) [24] => stdClass Object ( [bid] => 49 [name] => Kim Reed Conveyancing [imageurl] => sp_kimreed.jpg [clickurl] => ) [25] => stdClass Object ( [bid] => 45 [name] => Mordialloc Sporting Club [imageurl] => msc logo.jpg [clickurl] => ) ) Here's the php function which is meant to split the array: function split_array($array, $slices) { $perGroup = floor(count($array) / $slices); $Remainder = count($array) % $slices ; $slicesArray = array(); $i = 0; while( $i < $slices ) { $slicesArray[$i] = array_slice($array, $i * $perGroup, $perGroup); $i++; } if ( $i == $slices ) { if ($Remainder > 0 && $Remainder < $slices) { $z = $i * $perGroup +1; $x = 0; while ($x < $Remainder) { $slicesRemainderArray = array_slice($array, $z, $Remainder+$x); $remainderItems = array_merge($slicesArray[$x],$slicesRemainderArray); $slicesArray[$x] = $remainderItems; $x++; $z++; } } }; return $slicesArray; } Here's the result of the split (it somehow duplicates items from the original array into the smaller arrays): Array ( [0] => Array ( [0] => stdClass Object ( [bid] => 57 [name] => Southern Suburbs Physiotherapy Centre [imageurl] => sp_sspc.jpg [clickurl] => http://www.sspc.com.au ) [1] => stdClass Object ( [bid] => 35 [name] => Bendigo Bank Parkdale / Mentone East [imageurl] => sp_bendigo.gif [clickurl] => http://www.bendigobank.com.au ) [2] => stdClass Object ( [bid] => 38 [name] => Lowe Financial Group [imageurl] => sp_lowe.gif [clickurl] => http://lowefinancial.com/ ) [3] => stdClass Object ( [bid] => 39 [name] => Main Street Mordialloc [imageurl] => main street cafe.jpg [clickurl] => ) [4] => stdClass Object ( [bid] => 48 [name] => Beachside Osteo [imageurl] => sp_beachside.gif [clickurl] => http://www.beachsideosteo.com.au/ ) [5] => stdClass Object ( [bid] => 33 [name] => Two Brothers [imageurl] => sp_2brothers.gif [clickurl] => http://www.2brothers.com.au/ ) [6] => stdClass Object ( [bid] => 40 [name] => Ripponlea Mitsubishi [imageurl] => sp_mitsubishi.gif [clickurl] => ) ) [1] => Array ( [0] => stdClass Object ( [bid] => 44 [name] => Mordialloc Personal Trainers [imageurl] => sp_mordipt.gif [clickurl] => # ) [1] => stdClass Object ( [bid] => 41 [name] => Print House Graphics [imageurl] => sp_printhouse.gif [clickurl] => ) [2] => stdClass Object ( [bid] => 39 [name] => Main Street Mordialloc [imageurl] => main street cafe.jpg [clickurl] => ) [3] => stdClass Object ( [bid] => 48 [name] => Beachside Osteo [imageurl] => sp_beachside.gif [clickurl] => http://www.beachsideosteo.com.au/ ) [4] => stdClass Object ( [bid] => 33 [name] => Two Brothers [imageurl] => sp_2brothers.gif [clickurl] => http://www.2brothers.com.au/ ) [5] => stdClass Object ( [bid] => 40 [name] => Ripponlea Mitsubishi [imageurl] => sp_mitsubishi.gif [clickurl] => ) ) [2] => Array ( [0] => stdClass Object ( [bid] => 56 [name] => Logical Services [imageurl] => sp_logical.jpg [clickurl] => ) [1] => stdClass Object ( [bid] => 43 [name] => Systema [imageurl] => sp_systema.gif [clickurl] => ) [2] => stdClass Object ( [bid] => 48 [name] => Beachside Osteo [imageurl] => sp_beachside.gif [clickurl] => http://www.beachsideosteo.com.au/ ) [3] => stdClass Object ( [bid] => 33 [name] => Two Brothers [imageurl] => sp_2brothers.gif [clickurl] => http://www.2brothers.com.au/ ) [4] => stdClass Object ( [bid] => 40 [name] => Ripponlea Mitsubishi [imageurl] => sp_mitsubishi.gif [clickurl] => ) ) [3] => Array ( [0] => stdClass Object ( [bid] => 53 [name] => Carmotive [imageurl] => sp_carmotive.jpg [clickurl] => http://www.carmotive.com.au/ ) [1] => stdClass Object ( [bid] => 45 [name] => Mordialloc Sporting Club [imageurl] => msc logo.jpg [clickurl] => ) [2] => stdClass Object ( [bid] => 33 [name] => Two Brothers [imageurl] => sp_2brothers.gif [clickurl] => http://www.2brothers.com.au/ ) [3] => stdClass Object ( [bid] => 40 [name] => Ripponlea Mitsubishi [imageurl] => sp_mitsubishi.gif [clickurl] => ) ) [4] => Array ( [0] => stdClass Object ( [bid] => 59 [name] => Pure Sport [imageurl] => sp_psport.jpg [clickurl] => http://www.puresport.com.au/ ) [1] => stdClass Object ( [bid] => 54 [name] => PPM Builders [imageurl] => sp_ppm.jpg [clickurl] => http://www.hotfrog.com.au/Companies/P-P-M-Builders ) [2] => stdClass Object ( [bid] => 40 [name] => Ripponlea Mitsubishi [imageurl] => sp_mitsubishi.gif [clickurl] => ) ) [5] => Array ( [0] => stdClass Object ( [bid] => 46 [name] => Patterson Securities [imageurl] => cmyk patersons_withtag.jpg [clickurl] => ) [1] => stdClass Object ( [bid] => 34 [name] => Adriano's Pizza & Pasta [imageurl] => sp_adrian.gif [clickurl] => # ) ) [6] => Array ( [0] => stdClass Object ( [bid] => 55 [name] => 360South [imageurl] => sp_360.jpg [clickurl] => ) [1] => stdClass Object ( [bid] => 37 [name] => Mordialloc Cellar Door [imageurl] => sp_cellardoor.gif [clickurl] => ) ) [7] => Array ( [0] => stdClass Object ( [bid] => 49 [name] => Kim Reed Conveyancing [imageurl] => sp_kimreed.jpg [clickurl] => ) [1] => stdClass Object ( [bid] => 58 [name] => Dicount Lollie Shop [imageurl] => new dls logo.jpg [clickurl] => ) ) [8] => Array ( [0] => stdClass Object ( [bid] => 51 [name] => Richmond and Bennison [imageurl] => sp_richmond.jpg [clickurl] => http://www.richbenn.com.au/ ) [1] => stdClass Object ( [bid] => 52 [name] => Mordialloc Travel and Cruise [imageurl] => sp_morditravel.jpg [clickurl] => http://www.yellowpages.com.au/vic/mordialloc/mordialloc-travel-cruise-13492525-listing.html ) ) [9] => Array ( [0] => stdClass Object ( [bid] => 50 [name] => Letec [imageurl] => sp_letec.jpg [clickurl] => www.letec.biz ) [1] => stdClass Object ( [bid] => 36 [name] => Big River [imageurl] => sp_bigriver.gif [clickurl] => ) ) ) ^^ As you can see there are duplicates from the original array in the newly created smaller arrays. I thought I could remove the duplicates using a multi-dimensional remove duplicate function but that didn't work. I'm guessing my problem is in the array_split function. Any suggestions? :)

• Connect two UIScrollView's together

  - by johnw188

  Here's a tricky iPhone problem I've been working on. I have three UIScrollViews on a page, one that only scrolls horizontally, one that only scrolls vertically, and one that scrolls both horizontally and vertically. I want to lock the views together, so that the horizontal location of the horizontal only scrollview matches the horizontal location of the main scrollview, and the vertical scrollview likewise, so that dragging the main scrollview around controls the horizontal and vertical scrollviews. Problem is, I'm completely stumped. I've looked around inside the apple documentation, but there doesn't seem to be any way to do this officially. One thought that I had was to somehow "clone" any touch on any of the scrollviews to a point on the other two, but I have no idea how to do this. If anyone has any thoughts on this, I'd very much appreciate it.
