  • Cannot get a session with Facebook app? (using its Graph API)

    - by Jian Lin
    I have really simple few lines of Facebook app, using the new Facebook API: <pre> <?php require 'facebook.php'; // Create our Application instance. $facebook = new Facebook(array( 'appId' => '117676584930569', 'secret' => '**********', // hidden here on the post... 'cookie' => true, )); var_dump($facebook); ?> but it is giving me the following output: http://apps.facebook.com/woolaladev/i2.php would give out object(Facebook)#1 (6) { ["appId:protected"]=> string(15) "117676584930569" ["apiSecret:protected"]=> string(32) "**********" <--- just hidden on this post ["session:protected"]=> NULL <--- Session is NULL for some reason ["sessionLoaded:protected"]=> bool(false) ["cookieSupport:protected"]=> bool(true) ["baseDomain:protected"]=> string(0) "" } Session is NULL for some reason, but I am logged in and can access my home and profile and run other apps on Facebook (to see that I am logged on). I am following the sample on: http://github.com/facebook/php-sdk/blob/master/examples/example.php http://github.com/facebook/php-sdk/blob/master/src/facebook.php (download using raw URL: wget http://github.com/facebook/php-sdk/raw/master/src/facebook.php ) Trying on both hosting companies at dreamhost.com and netfirms.com, and the results are the same.

  • longest string in texts

    - by davit-datuashvili
    Ihave following code in Java: import java.util.*; public class longest{ public static void main(String[] args){ int t=0;int m=0;int token1, token2; String words[]=new String[10]; String word[]=new String[10]; String common[]=new String[10]; String text="saqartvelo gabrwyindeba da gadzlierdeba aucileblad "; String text1="saqartvelo gamtliandeba da gadzlierdeba aucileblad"; StringTokenizer st=new StringTokenizer(text); StringTokenizer st1=new StringTokenizer(text1); token1=st.countTokens(); token2=st1.countTokens(); while (st.hasMoreTokens()){ words[t]=st.nextToken(); t++; } while (st1.hasMoreTokens()){ word[m]=st1.nextToken(); m++; } for (int k=0;k<token1;k++){ for (int f=0;f<token2;f++){ if (words[f].compareTo(word[f])==0){ common[f]=words[f]; } } } while (i<common.length){ System.out.println(common[i]); i++; } } } I want that in common array put elements which i in both text or these words saqartvelo (georgia in english) da (and in english) gadzlierdeba (will be stronger) aucileblad (sure) and then between these words find string which has maximum length but it does not work more correctly it show me these words and also many null elements. How do I correct it?

  • problem getting info from a cookie with javascript

    - by Jason
    I am having an issue with my cookies and I can't figure it out. Basically I have it set up so it checks for the cookie to see if the user is logged in, and then displays either a welcome message or a login link. It works - except that instead of returning the persons name in the welcome message it just is blank where the name should be. The cookie is there, with all the appropriate info.. not sure what I am doing wrong. var itm = new Array(); itm[0] = findCookie("ui"); if (itm[0] == null) { document.write("<h2><a href='logreg.html'>Log In or Sign Up</a></h2>"); } else { var c1 = itm[0].indexOf(","); var c2 = itm[0].indexOf(",",c1); var c3 = itm[0].indexOf(",",c2); var gname = itm[0].substring(c2,c3); document.write("<h2>Welcome "+gname+"!</h2>"); } The findCookie function is.. function findCookie(val){ var cookie = null; var findVal = val + "="; var dc = document.cookie; if (dc.length > 0) { var start = dc.indexOf(findVal); if (start >= 0) { start += findVal.length; lastVal = dc.indexOf(";", start); if (lastVal == -1) { lastVal = dc.length; } cookie = (dc.substring(start, lastVal)); } else { return cookie; } } return cookie; }

  • CodeIgniter's Scaffolding and Helper Functions Not Working

    - by 01010011
    Hi, I'm following CodeIgniter's tutorial "Create a blog in 20 minutes" and I am having trouble getting the helper, anchor and Scaffolding functions to work. I can't seem to create links on my HTML page using the helper and anchor functions. I put $this->load->helper('url'); $this->load->helper('form'); in the constructor under parent::Controller(); and <p>&lt;?php anchor('blog/comments','Comments'); ?&gt;</p> within the foreach loop as specified in the tutorial. But Im not getting the links to appear. Secondly, I keep getting a 404 Page Not Found error whenever I try to access CodeIgniter's Scaffolding page in my browser, like so: localhost/codeignitor/index.php/blog/scaffolding/mysecretword I can access localhost/codeignitor/index.php/blog just fine. 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 assistance will be appreciated. Thanks in advance?

  • PHP XML Strategy: Parsing DOM to fill "Bean"

    - by Mike
    I have a question concerning a good strategy on how to fill a data "bean" with data inside an xml file. The bean might look like this: class Person { var $id; var $forename = ""; var $surname = ""; var $bio = new Biography(); } class Biography { var $url = ""; var $id; } the xml subtree containing the info might look like this: <root> <!-- some more parent elements before node(s) of interest --> <person> <name pre="forename"> Foo </name> <name pre="surname"> Bar </name> <id> 1254 </id> <biography> <url> http://www.someurl.com </url> <id> 5488 </id> </biography> </person> </root> At the moment, I have one approach using DOMDocument. A method iterates over the entries and fills the bean by "remembering" the last node. I think thats not a good approach. What I have in mind is something like preconstructing some xpath expression(s) and then iterate over the subtrees/nodeLists. Return an array containing the beans as defined above eventually. However, it seems not to be possible reusing a subtree /DOMNode as DOMXPath constructor parameter. Has anyone of you encountered such a problem?

  • Calculating odds distribution with 6-sided dice

    - by Stephen
    I'm trying to calculate the odds distribution of a changing number of 6-sided die rolls. For example, 3d6 ranges from 3 to 18 as follows: 3:1, 4:3, 5:6, 6:10, 7:15, 8:21, 9:25, 10:27, 11:27, 12:25, 13:21, 14:15, 15:10, 16:6, 17:3, 18:1 I wrote this php program to calculate it: function distributionCalc($numberDice,$sides=6) { for ( $i=0; $i<pow($sides,$numberDice); $i++) { $sum=0; for ($j=0; $j<$numberDice; $j++) { $sum+=(1+(floor($i/pow($sides,$j))) % $sides); } $distribution[$sum]++; } return $distribution; } The inner $j for-loop uses the magic of the floor and modulus functions to create a base-6 counting sequence with the number of digits being the number of dice, so 3d6 would count as: 111,112,113,114,115,116,121,122,123,124,125,126,131,etc. The function takes the sum of each, so it would read as: 3,4,5,6,7,8,4,5,6,7,8,9,5,etc. It plows through all 3^6 possible results and adds 1 to the corresponding slot in the $distribution array between 3 and 18. Pretty straightforward. However, it only works until about 8d6, afterward i get server time-outs because it's now doing billions of calculations. But I don't think it's necessary because die probability follows a sweet bell-curve distribution. I'm wondering if there's a way to skip the number crunching and go straight to the curve itself. Is there a way to do this, so, for example, with 80d6 (80-480)? Can the distribution be projected without doing 6^80 calculations? I'm not a professional coder and probability is still new to me, so thanks for all the help! Stephen

  • How do I DRY up my CouchDB views?

    - by James A. Rosen
    What can I do to share code among views in CouchDB? Example 1 -- utility methods Jesse Hallett has some good utility methods, including function dot(attr) { return function(obj) { return obj[attr]; } } Array.prototype.map = function(func) { var i, r = [], for (i = 0; i < this.length; i += 1) { r[i] = func(this[i]); } return r; }; ... Where can I put this code so every view can access it? Example 2 -- constants Similarly for constants I use in my application. Where do I put MyApp = { A_CONSTANT = "..."; ANOTHER_CONSTANT = "..."; }; Example 3 -- filter of a filter: What if I want a one view that filters by "is this a rich person?": function(doc) { if (doc.type == 'person' && doc.net_worth > 1000000) { emit(doc.id, doc); } } and another that indexes by last name: function(doc) { if (doc.last_name) { emit(doc.last_name, doc); } } How can I combine them into a "rich people by last name" view? I sort of want the equivalent of the Ruby my_array.select { |x| x.person? }.select { |x| x.net_worth > 1,000,000 }.map { |x| [x.last_name, x] } How can I be DRYer?

  • Strange ng-model behavior inside ng-repeat

    - by Mike Fisher
    I'm trying to build up a complex post request to run a report in my Angular app. I have a list of inputs all dynamically generated via an ng-repeat a simple version of my html looks like this. <div ng-repeat="filter in lists.filters"> <input type="checkbox" ng-model="report.options.filters[filter.value]['type']/> <input type="text" ng-model="report.options.filters[filter.value]['values']/> </div> ng-repeat is looping over this array [ {name: 'Advertisers', value: 'advertisers'}, {name: 'Sizes', value: 'sizes'}, {name: 'Campaign IDs', value: 'campaigns'}, {name: 'Creative IDs', value: 'creatives'}, {name: 'Publishers', value: 'publishers'}, {name: 'Placement IDs', value: 'placements'}, {name: 'Seller Types', value: 'seller_types'}, {name: 'Impression Types', value: 'impression_types'}, {name: 'Bid Types', value: 'bid_types'}, {name: 'Seller Members', value: 'seller_members'}, {name: 'Buyer Members', value: 'buyer_members'}, {name: 'Insertion Order Ids', value: 'insertion_orders'}, {name: 'Countries', value: 'countries'}, {name: 'Site Ids', value: 'sites'}, {name: 'Sources', value: 'sources'} ]; The JSON I'm sending back needs to be structured like this: "filters": { "state": "all", "campaigns": {type:"include", values":[1,2]}, "creatives": {type:"exclude","values":[1,2]}, "publishers": {"values":[1,2]}, "placements": {type:"exclude",values":[1,2]}, "advertisers": {"values":[1,2]}, "sizes": {"values":[1,2]}, "countries": {"values":[1,2]}, "insertion_orders": {"values":[1,2]}, "sites": {"values":[1,2]}, "bid_types": {"values":[1,2]}, "seller_types": {"values":[1,2]}, "impression_types": {"values":[1,2]}, "seller_members": {"values":[1,2]}, "buyer_members": {"values":[1,2]}, "sources": {"values":[1,2]} } When I do this Angular throws an error: 'Cannot set property 'values' of undefined' and 'Cannot set property 'type' of undefined' Yet if I do this (inside ng-repeat) <input type="text" ng-model="report.options.filters[filter.value]/> Or this outside of ng-repeat <input type="text" ng-model="report.options.filters[filter.value]['values']/> No errors are thrown and everything works fine. I'm positive that filter.value is defined and available on the scope even though Angular thinks it's not for some reason. I'm not quite sure what I'm doing wrong. Any help is much appreciated.

  • Websql to google maps markers

    - by Roy van Neden
    I am busy with my web application for a school project. It has has two pages. The first page uploads the location(latitude and longitude), price, date and kind of fuel. It works and i saved it with websql.(see screenshot) Now i want to get everything out of the web database and put it as a marker on my google maps card. I have my own location already. But i dont know how to get everything from the database to the map as a marker. I'm using jquery mobile/html5/css/javascript only. Code to put it in a array or something else that will work. db.transaction(function(tx){ tx.executeSql('SELECT brandstofsoort, literprijs, datum, latitude, longitude FROM brandstofstatus', [], function (tx, results) { var lengte = results.rows.length, i; for(var i = 0; i< lengte; i++){ var locations = [ [ ], [ ], [ ], [ ], [ ] ]; } // / for loop });// /tx.executeSql });// /db.transaction Thanks in advance!

  • How to debug anomalous C memory/stack problems

    - by EBM
    Hello, Sorry I can't be specific with code, but the problems I am seeing are anomalous. Character string values seem to be getting changed depending on other, unrelated code. For example, the value of the argument that is passed around below will change merely depending on if I comment out one or two of the fprintf() calls! By the last fprintf() the value is typically completely empty (and no, I have checked to make sure I am not modifying the argument directly... all I have to do is comment out a fprintf() or add another fprintf() and the value of the string will change at certain points!): static process_args(char *arg) { /* debug */ fprintf(stderr, "Function arg is %s\n", arg); ...do a bunch of stuff including call another function that uses alloc()... /* debug */ fprintf(stderr, "Function arg is now %s\n", arg); } int main(int argc, char *argv[]) { char *my_arg; ... do a bunch of stuff ... /* just to show you it's nothing to do with the argv array */ my_string = strdup(argv[1]); /* debug */ fprintf(stderr, "Argument 1 is %s\n", my_string); process_args(my_string); } There's more code all around, so I can't ask for someone to debug my program -- what I want to know is HOW can I debug why character strings like this are getting their memory changed or overwritten based on unrelated code. Is my memory limited? My stack too small? How do I tell? What else can I do to track down the issue? My program isn't huge, it's like a thousand lines of code give or take and a couple dynamically linked external libs, but nothing out of the ordinary. HELP! TIA!

  • How to pass binary data between two apps using Content Provider?

    - by Viktor
    I need to pass some binary data between two android apps using Content Provider (sharedUserId is not an option). I would prefer not to pass the data (a savegame stored as a file, small in size < 20k) as a file (ie. overriding openFile()) since this would necessitate some complicated temp-file scheme to cope with concurrency with several content provider accesses and a running game. I would like to read the file into memory under a mutex lock and then pass the binary array in the simplest way possible. How do I do this? It seems creating a file in memory is not a possibility due to the return type of openFile(). query() needs to return a Cursor. Using MatrixCursor is not possible since it applies toString() to all stored objects when reading it. What do I need to do? Implement a custom Cursor? This class has 30 abstract methods. Do I read the file, put it in a SQLite db and return the cursor? The complexity of this seemingly simple task is mindboggling.

  • Threading is slow and unpredictable?

    - by Jake
    I've created the basis of a ray tracer, here's my testing function for drawing the scene: public void Trace(int start, int jump, Sphere testSphere) { for (int x = start; x < scene.SceneWidth; x += jump) { for (int y = 0; y < scene.SceneHeight; y++) { Ray fired = Ray.FireThroughPixel(scene, x, y); if (testSphere.Intersects(fired)) sceneRenderer.SetPixel(x, y, Color.Red); else sceneRenderer.SetPixel(x, y, Color.Black); } } } SetPixel simply sets a value in a single dimensional array of colours. If I call the function normally by just directly calling it it runs at a constant 55fps. If I do: Thread t1 = new Thread(() => Trace(0, 1, testSphere)); t1.Start(); t1.Join(); It runs at a constant 50fps which is fine and understandable, but when I do: Thread t1 = new Thread(() => Trace(0, 2, testSphere)); Thread t2 = new Thread(() => Trace(1, 2, testSphere)); t1.Start(); t2.Start(); t1.Join(); t2.Join(); It runs all over the place, rapidly moving between 30-40 fps and sometimes going out of that range up to 50 or down to 20, it's not constant at all. Why is it running slower than it would if I ran the whole thing on a single thread? I'm running on a quad core i5 2500k.

  • Why is an Add method required for { } initialization?

    - by Dan Tao
    To use initialization syntax like this: var contacts = new ContactList { { "Dan", "[email protected]" }, { "Eric", "[email protected]" } }; ...my understanding is that my ContactList type would need to define an Add method that takes two string parameters: public void Add(string name, string email); What's a bit confusing to me about this is that the { } initializer syntax seems most useful when creating read-only or fixed-size collections. After all it is meant to mimic the initialization syntax for an array, right? (OK, so arrays are not read-only; but they are fixed size.) And naturally it can only be used when the collection's contents are known (at least the number of elements) at compile-time. So it would almost seem that the main requirement for using this collection initializer syntax (having an Add method and therefore a mutable collection) is at odds with the typical case in which it would be most useful. I'm sure I haven't put as much thought into this matter as the C# design team; it just seems that there could have been different rules for this syntax that would have meshed better with its typical usage scenarios. Am I way off base here? Is the desire to use the { } syntax to initialize fixed-size collections not as common as I think? What other factors might have influenced the formulation of the requirements for this syntax that I'm simply not thinking of?

  • Add Zend_Navigation to the View with old legacy bootstrap

    - by Grant Collins
    Hi, I've been struggling with Zend_Navigation all weekend, and now I have another problem, which I believe has been the cause of a lot of my issues. I am trying to add Zend_Navigation to a legacy 1.7.6 Zend Framework application, i've updated the Zend Library to 1.9.0 and updated the bootstrap to allow this library update. The problem is that I don't know how, and the examples show the new bootstrap method of how to add the Navigation object to the view, I've tried this: //initialise the application layouts with the MVC helpers $layout = Zend_Layout::startMvc(array('layoutPath' => '../application/layouts')); $view = $layout->getView(); $configNav = new Zend_Config_Xml('../application/config/navigation.xml', 'navigation'); $navigation = new Zend_Navigation($configNav); $view->navigation($navigation); $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer(); $viewRenderer->setView($view); This seems to run through fine, but when I go to use the breadcrumb view helper in my layout, it errors with: Strict Standards: Creating default object from empty value in C:\www\moobia\development\website\application\modules\employers\controllers\IndexController.php on line 27 This is caused by the following code in the init() function of my controller. $uri = $this->_request->getPathInfo(); $activeNav = $this->view->navigation()->findByUri($uri); <- this is null when called $activeNav->active = true; I believe it's because the Zend_Navigation object is not in the view. I would look at migrating the bootstrap to the current method, but at present I am running out of time for a release. Thanks, Grant

  • What ever happened to APL?

    - by lkessler
    When I was at University 30 years ago, I used a programming language called APL. I believe the acronym stood for "A Programming Language", This language was interpretive and was especially useful for array and matrix operations with powerful operators and library functions to help with that. Did you use APL? Is this language still in use anywhere? Is it still available, either commercially or open source? I remember the combinatorics assignment we had. It was complex. It took a week of work for people to program it in PL/1 and those programs ranged from 500 to 1000 lines long. I wrote it in APL in under an hour. I left it at 10 lines for readability, although I should have been a purist and worked another hour to get it into 1 line. The PL/1 programs took 1 or 2 minutes to run on the IBM mainframe and solve the problem. The computer charge was $20. My APL program took 2 hours to run and the charge was $1,500 which was paid for by our Computer Science Department's budget. That's when I realized that a week of my time is worth way more than saving some $'s in someone else's budget. I got an A+ in the course. p.s. Don't miss this presentation entitled: "APL one of the greatest programming languages ever"

  • Endless problems with a very simple python subprocess.Popen task

    - by Thomas
    I'd like python to send around a half-million integers in the range 0-255 each to an executable written in C++. This executable will then respond with a few thousand integers. Each on one line. This seems like it should be very simple to do with subprocess but i've had endless troubles. Right now im testing with code: // main() u32 num; std::cin >> num; u8* data = new u8[num]; for (u32 i = 0; i < num; ++i) std::cin >> data[i]; // test output / spit it back out for (u32 i = 0; i < num; ++i) std::cout << data[i] << std::endl; return 0; Building an array of strings ("data"), each like "255\n", in python and then using: output = proc.communicate("".join(data))[0] ...doesn't work (says stdin is closed, maybe too much at one time). Neither has using proc.stdin and proc.stdout worked. This should be so very simple, but I'm getting constant exceptions, and/or no output data returned to me. My Popen is currently: proc = Popen('aux/test_cpp_program', stdin=PIPE, stdout=PIPE, bufsize=1) Advise me before I pull my hair out. ;)

    I have a really tricky thing going up here. My project has around 100 tables and they are all mapped by LINQ. Everything works fine in a dev and test environment. These enviroments are MS Win 2008 r2 servers with SQL 2008 sp1 databases. IIS and SQL are on a different machines. Now on production enviroment which is MS Win 2003 x64 web farm + geoclustered SQL 2008 IT DOES not work.

  • Testing background audio in the simulator

    - by Cactuar
    I'm experimenting with the new background audio service in iPhone OS 4.0 but I can't get it to work in the simulator. According to this page: iPhone Application Programming Guide: Executing Code in the Background it seems that all I have to do is add the a UIBackgroundModes key with an array containing audio to my Info.plist file and the audio my application plays should automatically continue when I switch to another app. I have done this but the audio still pauses as I switch to another app, when I switch back it continues where it left off. This is the code I'm using to play the sound: NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/audio.mp3", [[NSBundle mainBundle] resourcePath]]]; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; audioPlayer.numberOfLoops = -1; if (audioPlayer == nil) NSLog(@"%@", [error userInfo]); else [audioPlayer play]; Has anyone gotten this to work? Could it be that it would work on an actual device and it's just a problem with the simulator? I'm a bit hesitant to install 4.0 on my phone since I've heard it's still very buggy. Wish I had another device to use only for development.

  • jquery .live() event interactions

    - by ddango
    Let's say I have a scenario where I have a global plugin (or at least a plugin that binds to a wider array of events). This plugin takes a selector, and binds a live click to it. Something in pseudo-jquery that might look like this: $.fn.changeSomething = function(){ $(this).live("change", function(){ alert("yo");}); } On another page, I have an additional live binding something like this: $("input[type='checkbox']").live("click", function(){alert("ho");}); Within this scenario, the checkbox would ideally end up being bound to both live events. What I'm seeing is that the change event fires as it should, and I'm alerted "yo". However, using this live click event, I never trigger it. However, using an explicit click binding, I DO hit it. The easy workaround is to trigger a click event at the end of the live change handler, but this seems janky to me. Any ideas? Note that this is using jquery 1.4.2 and only occurs in IE8 (I supposed 6/7 would too, but I haven't tested them).

  • structured vs. unstructured data in db

    - by Igor
    the question is one of design. i'm gathering a big chunk of performance data with lots of key-value pairs. pretty much everything in /proc/cpuinfo, /proc/meminfo/, /proc/loadavg, plus a bunch of other stuff, from several hundred hosts. right now, i just need to display the latest chunk of data in my UI. i will probably end up doing some analysis of the data gathered to figure out performance problems down the road, but this is a new application so i'm not sure what exactly i'm looking for performance-wise just yet. i could structure the data in the db -- have a column for each key i'm gathering. the table would end up being O(100) columns wide, it would be a pain to put into the db, i would have to add new columns if i start gathering a new stat. but it would be easy to sort/analyze the data just using SQL. or i could just dump my unstructured data blob into the table. maybe three columns -- host id, timestamp, and a serialized version of my array, probably using JSON in a TEXT field. which should I do? am i going to be sorry if i go with the unstructured approach? when doing analysis, should i just convert the fields i'm interested in and create a new, more structured table? what are the trade-offs i'm missing here?

  • Using stdint.h and ANSI printf?

    - by nn
    Hi, I'm writing a bignum library, and I want to use efficient data types to represent the digits. Particularly integer for the digit, and long (if strictly double the size of the integer) for intermediate representations when adding and multiplying. I will be using some C99 functionality, but trying to conform to ANSI C. Currently I have the following in my bignum library: #include <stdint.h> #if defined(__LP64__) || defined(__amd64) || defined(__x86_64) || defined(__amd64__) || defined(__amd64__) || defined(_LP64) typedef uint64_t u_w; typedef uint32_t u_hw; #define BIGNUM_DIGITS 2048 #define U_HW_BITS 16 #define U_W_BITS 32 #define U_HW_MAX UINT32_MAX #define U_HW_MIN UINT32_MIN #define U_W_MAX UINT64_MAX #define U_W_MIN UINT64_MIN #else typedef uint32_t u_w; typedef uint16_t u_hw; #define BIGNUM_DIGITS 4096 #define U_HW_BITS 16 #define U_W_BITS 32 #define U_HW_MAX UINT16_MAX #define U_HW_MIN UINT16_MIN #define U_W_MAX UINT32_MAX #define U_W_MIN UINT32_MIN #endif typedef struct bn { int sign; int n_digits; // #digits should exclude carry (digits = limbs) int carry; u_hw tab[BIGNUM_DIGITS]; } bn; As I haven't written a procedure to write the bignum in decimal, I have to analyze the intermediate array and printf the values of each digit. However I don't know which conversion specifier to use with printf. Preferably I would like to write to the terminal the digit encoded in hexadecimal. The underlying issue is, that I want two data types, one that is twice as long as the other, and further use them with printf using standard conversion specifiers. It would be ideal if int is 32bits and long is 64bits but I don't know how to guarantee this using a preprocessor, and when it comes time to use functions such as printf that solely rely on the standard types I no longer know what to use.

  • AutoMapper and flattening nested arrays

    - by Bryan Slatner
    I'm trying to use AutoMapper to flatten multiple levels of arrays. Consider the following source classes: class X { public string A { get; set; } public Y[] B { get; set; } } class Y { public string C { get; set; } public Z[] D { get; set; } } class Z { public string E { get; set; } public string F { get; set; } } And the following destination: class Destination { public string A { get; set; } public string C { get; set; } public string E { get; set; } public string F { get; set; } } What I'd like to be able to do is get a List from one or more X, e.g.: Mapper.Map<IEnumerable<X>, IEnumerable<Destination>>(arrayOfX); I'm unable to figure out what sort of mapping configuration to use to achieve this. MapFrom seems like the way to go for 1:1 compositions, but doesn't seem to be able to handle the array (or other enumerable) unless I use AutoMapper's destination naming convention. Any insights on how to achieve this?

  • New Perl user: using a hash of arrays

    - by Zach H
    I'm doing a little datamining project where a perl script grabs info from a SQL database and parses it. The data consists of several timestamps. I want to find how many of a particular type of timestamp exist on any particular day. Unfortunately, this is my first perl script, and the nature of perl when it comes to hashes and arrays is confusing me quite a bit. Code segment: my %values=();#A hash of the total values of each type of data of each day. #The key is the day, and each key stores an array of each of the values I need. my @proposal; #[drafted timestamp(0), submitted timestamp(1), attny approved timestamp(2),Organiziation approved timestamp(3), Other approval timestamp(4), Approved Timestamp(5)] while(@proposal=$sqlresults->fetchrow_array()){ #TODO: check to make sure proposal is valid #Increment the number of timestamps of each type on each particular date my $i; for($i=0;$i<=5;$i++) $values{$proposal[$i]}[$i]++; #Update rolling average of daily #TODO: To check total load, increment total load on all dates between attourney approve date and accepted date for($i=$proposal[1];$i<=$proposal[2];$i++) $values{$i}[6]++; } I keep getting syntax errors inside the for loops incrementing values. Also, considering that I'm using strict and warnings, will Perl auto-create arrays of the right values when I'm accessing them inside the hash, or will I get out-of bounds errors everywhere? Thanks for any help, Zach
