  • a Facebook app beginner question

    - by Robert
    Dear all, I have written up my first php script to learn facebook API stuff.It goes like this: require_once('facebook/client/facebook.php'); $facebook = new Facebook('0fff13540b7ff2ae94be38463cb4fa67','8a029798dd463be6c94cb8d9ca851696'); http://stackoverflow.com/questions/ask $fb_user = $facebook-require_login(); ? Hello ' useyou='false' possessive='true' /! Welcome to my first application! I put "facebook.php" in the same directory as my php script. However,after I deploy the php on a web server and link it with facebook and run it,I got error saying: "Fatal error: Call to undefined method Facebook::require_login() in /home/a2660104/public_html/facebook-php-sdk-94fcb13/src/default.php on line 16" Could anyone help me a bit on this?I am a beginner to the facebook app programming.Thanks a lot!

  • Setting up separate ctags db's for C/C++ standard libs, boost, and third party libs

    - by Robert S. Barnes
    I want to set up separate ctags databases for various libraries in /usr/include/ for use with OmniCppComplete. The idea is to be able to pull in only the libraries needed for a particular project in the target language - C or C++. For example, I'd like to have one database for the standard C libraries, one for system libraries that might be used by either C or C++ programs ( sockets / networking comes to mind ) one for the standard C++ libs / STL / Boost, and then other databases for various third party libraries such as QT or glib. Then I could pull something in simply by typing set tags+= ~/.vim/somelib.tags in vim. I assume that everything related to the C++ stdlib and STL are in the /usr/include/c++ and that Boost is all in /usr/include/boost. Unfortunately it seems that the standard C libs and system libs are just kind of dumped directly into /usr/include/ with a variety of other stuff. How can I get a list of which files and directories belong to which libs? I'm on Ubuntu 8.04.

  • Smarty: including a template file from the same directory

    - by Robert Munteanu
    I have a Smarty template located in a directory under templates_dir: templates/some/dir/template.tpl . In the same directory, I have a sub-template: templates/some/dir/_component.tpl . I can't include the sub-component using an unqualified include, since apparently it looks it up under the templates_dir: {include file='_component.tpl'} How can I tell Smarty to read the file from the same directory, as opposed to the templates root ? I do not want to specify absolute paths, since it will cause problems when changing directory structures.

  • LINQ - Using where or join - Performance difference ?

    - by Patrick Säuerl
    Hi Based on this question: http://stackoverflow.com/questions/3013034/what-is-difference-between-where-and-join-in-linq My question is following: Is there a performance difference in the following two statements: from order in myDB.OrdersSet from person in myDB.PersonSet from product in myDB.ProductSet where order.Persons_Id==person.Id && order.Products_Id==product.Id select new { order.Id, person.Name, person.SurName, product.Model,UrunAdi=product.Name }; and from order in myDB.OrdersSet join person in myDB.PersonSet on order.Persons_Id equals person.Id join product in myDB.ProductSet on order.Products_Id equals product.Id select new { order.Id, person.Name, person.SurName, product.Model,UrunAdi=product.Name }; I would always use the second one just because it´s more clear. My question is now, is the first one slower than the second one? Does it build a cartesic product and filters it afterwards with the where clauses ? Thank you.

  • OO Design: use Properties or Overloaded methods?

    - by Robert Frank
    Question about OO design. Suppose I have a base object vehicle. And two descendants: truck and automobile. Further, suppose the base object has a base method: FixFlatTire(); abstract; When the truck and automobile override the base object's, they require different information from the caller. Am I better off overloading FixFlatTire like this in the two descendant objects: Procedure Truck.FixFlatTire( OfficePhoneNumber: String; NumberOfAxles: Integer): Override; Overload; Procedure Automobile.FixFlatTire( WifesPhoneNumber: String; AAAMembershipID: String): Override; Overload; Or introducing new properties in each of the descendants and then setting them before calling FixFlatTire, like this: Truck.OfficePhoneNumber := '555-555-1212'; Truck.NumberOfAxles := 18; Truck.FixFlatTire(); Automobile.WifesPhoneNumber := '555-555-2323'; Automobile.AAAMembershipID := 'ABC'; Automobile.FixFlatTire();

  • How to search array for duplicates using a single array?

    - by patrick
    I am checking a list of 10 spots, each spot w/ 3 top users to see if a user is in an array before echoing and storing. foreach($top_10['top_10'] as $top10) //loop each spot { $getuser = ltrim($top10['url'], " users/" ); //strip url if ($usercount < 3) { if ((array_search($getuser, $array) !== true)) { echo $getuser; $array[$c++] = $getuser; } else { echo "duplicate <br /><br />"; } } } The problem I am having is that for every loop, it creates a multi-dimensional array for some reason which only allows array_search to search the current array and not all combined. I am wanting to store everything in the same $array. This is what I see after a print_r($array) Array ( [0] => 120728 [1] => 205247 ) Array ( [0] => 232123 [1] => 091928 )

  • Preventing fixed footer from overlapping content

    - by Robert Morgan
    I've fixed my footer DIV to the bottom of the viewport as follows: #Footer { position: fixed; bottom: 0; } This works well if there isn't much content on the page. However, if the content fills the full height of the page (i.e. the vertical scroll bar is visible) the footer overlaps the content, which I don't wont. How can I get the footer to stick to the bottom of the viewport, but never overlap the content?

  • CSS/Javascript: multiple columns

    - by Patrick
    hi, I'm looking for a columnizer plugin (making columns of my small divs). It is very important it has the following features: 1) It has to be as light as possible (if it is only css would be great, but I guess it is difficult make it work on IE then...) 2) It has to be cross-browser (I don't need IE6... IE7 and IE8 compatibility is required). 3) The divs has not to be broken. In other terms, the nodes have to be moved to next block but not splitted in 2. The nodes are div elements, they might include other divs, images and text. 4) The column have to have a fixed width and fixed margin. This means that when I resize the browser, and new columns are created (become the window becomes wider), the new columns have to rigidly keep the same width and distance between them. (margin:20px) (width:200px) Would be great to have some css.. but I'm afraid I need some jQuery plugin because I need all 4 features being supported. I found several plugins and css styleshits with very good solutions, but I couldn't find a complete one. Thanks

  • Hibernate NamingStrategy implementation that maintains state between calls

    - by Robert Petermeier
    Hi, I'm working on a project where we use Hibernate and JBoss 5.1. We need our entity classes to be mapped to Oracle tables that follow a certain naming convention. I'd like to avoid having to specify each table and column name in annotations. Therefore, I'm currently considering implementing a custom implementation of org.hibernate.cfg.NamingStrategy. The SQL naming conventions require the name of columns to have a suffix that is equivalent to a prefix of the table name. If there is a table "T100_RESOURCE", the ID column would have to be named "RES_ID_T100". In order to implement this in a NamingStrategy, the implementation would have to maintain state, i.e. the current class name it is creating the mappings for. It would rely on Hibernate to always call classToTableName() before propertyToColumnName() and to determine all column names by calling propertyToColumnName() before the next call to classToTableName() Is it safe to do that or are there situations where Hibernate will mix things up? I am not thinking of problems through multiple threads here (which can be solved by keeping the last class name in a ThreadLocal) but also of Hibernate deliberately calling this out of order in certain circumstances. For example Hibernate asking for mappings of three properties of class A, then one of class B, then again more attributes of class A.

  • php extending but with a new constructor...possible?

    - by Patrick
    I have a class: class test { function __construct() { print 'hello'; } function func_one() { print 'world'; } } what I would like to do is a have a class that sort of extends the test class. I say 'sort of', because the class needs to be able to run whatever function the test class is able to run, but NOT run the construct unless I ask it to. I do not want to override the construct. Anyone has any idea how to achieve this?

  • Dynamically include files in MSI setup

    - by Patrick Klug
    I am trying to deploy a bunch of files in a directory in my MSI setup. As the files will change frequently I don't want to add the files directly but rather have a way of automatically including all files from within a directory and deploy them to a certain location. I am using a Visual Studio Setup Project. Anybody know how/if this is possible?

  • Creating a floating button

    - by Robert Smith
    Hey all, I'm working on a Firefox extension and am out of ideas on how to implement a floating button. I need a button that is overlayed on my page that I can show/hide and dynamically position just about anywhere on my page. I thought I could do something like a fancy CSS tool-tip except replace it with button functionality, but that idea failed because I couldn't pull my example apart well enough to understand what all I need to include, need to change, etc. I've thought about using jQuery(though wouldn't mind avoiding, unless it makes this painfully easy) but will be looking more into that as a possibility now. If anyone can offer a tutorial link, ideas, sample code, anything to help get me moving in the right direction I will greatly appreciate it! Thanks! Edit: Clarification I'm not entirely sure how to actually create the overlayed button. I tried to create a a floating div with some text in it, and nothing showed up, but I got no errors, which means I'm doing something wrong, but I have no idea what that is. http://www.fijiwebdesign.com/blog/css-tooltips-floating-html-elements.html If you take a look at that webpage you see that there is that floating "feedback" button, I would like to create something similar, only it wouldn't be anchored to the sides, but I could position it over text, etc. #floatingBtn { position: absolute; z-index: 10000; top: 50%; left: 50%; } Thats the CSS I used to try and float my div. I don't know if I'm creating the div in the wrong place or... I thought if I could get a floating div with some text, I could turn that into my button.

  • "Socket operation on non-socket" error due to strange sytax

    - by Robert S. Barnes
    I ran across the error Socket operation on non-socket in some of my networking code when calling connect and spent a lot of time trying to figure out what was causing it. I finally figured out that the following line of code was causing the problem: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol) < 0)) { See the problem? Here's what the line should look like: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol)) < 0) { What I don't understand is why the first, incorrect line doesn't produce a warning. To put it another way, shouldn't the general form: if ( foo = bar() < baz ) do_somthing(); look odd to the compiler, especially running with g++ -Wall -Wextra? If not, shouldn't it at least show up as "bad style" to cppcheck, which I'm also running as part of my compile?

  • PHP/codeigniter - use of exit()

    - by Patrick
    I have a few pages that require login, so all controllers that link to these pages start with $this->checkSession(); //...rest of the code CheckSession should verify the session is still live, otherwise display a message and stop the execution of the rest of the code in the controller: function checkSession() { if (!$this->session->userdata('is_logged_in')) { //the session has expired! $data['main'] = 'confirmation_message'; $data['title'] = "Session expired"; $this->load->vars($data); $this->load->view('template'); exit(); } } . I was expecting these instructions to happen in sequence, but I only get a blank page. How can I make sure exit() gets executed only after all views are loaded?

  • Stored proc in .net dataset class vs studio management

    - by Robert
    Morning all. Got myself a simple query which returns ten rows in SQL Server Management Studio. I call the stored proc by right clicking it and feeding in the parameters. The results are returned immediately. In .NET we have set up a dataset class, added a table adapter whose select is this same procedure. I pass in the very same parameters and the execution times out after the standard 30 seconds. It continues to run immediately when called in sql server management studio. Any ideas why the execution time is seemingly infinite in the .net dataset class. The query is very simple.

  • Name for a "naive" timekeeping system?

    - by Robert L
    I am thinking of a "naive" timekeeping system of the sort I believe would be likely to be implemented by non-specialists. A day is exactly 24 hours. An hour is exactly 60 minutes. A minute is exactly 60 seconds. No exceptions (i.e. no Daylight Saving or leap seconds). A leap year occurs exactly once every four years: if the year modulo 4 equals 0, it is a leap year. The month lengths are the normal 31 days for January, 28 or 29 days for February, etc., that you would expect to find on a wall calendar. Days of the week, if they are used, are what you would get by taking your contemporary (late 1900's / early 2000's) wall calendar and, using the above rules for leap years and month lengths, extrapolating in both directions: if the calendar goes far back enough, February 29, 1900 exists and is a Wednesday; and if the calendar goes far forward enough, February 29, 2100 exists and is a Monday. What name, if any, is used to describe precisely this system?

  • Looking for early paper about compiling object-oriented code

    - by Robert Kosara
    I remember reading a paper a long time ago that talked about object-oriented programming. I believe that this was from the early 1980s or perhaps even before then. This was at the time when object-oriented programming was still done through pre-processors, and one thing that stuck with me is this: it argued that you could write code in either procedural or object-oriented fashion, and after preprocessing/compiling, you would end up with the exact same machine code. Does anybody know which paper I'm talking about?

  • how to convert numbers to alpha numeric system with php

    - by Patrick
    Im not sure what this is called, which is why im having trouble searching for it. What im looking to do, is take numbers, and convert them to some alpha numeric base so that the number say 5000, wouldnt read 5000, but like G4u or something like that. The idea being to save space and also not make it obvious how many records there are in a given system. Im using php, so if there is something like this built into php even better, but even a name for this method would be helpful at this point Again, sorry for not being able to be more clear, im just not sure what this is called.

  • Visual Studio 2008 having problems with namespaces when used as type in Generic coolection

    - by patrick
    I just upgraded last week from Visual Studio 2005 to 2008. I am having an issue with compiler resolving namespaces when I use a class as a type in a Generic collection. Intellisense recognizes the class and the compiler generates no errors when I use the class except when it is a type in a Generic collection declaration either as return type for a Property or as a parameter to a method. This is happening in my only project that is targeting the 3.5 framework, but changing the project containing the class to use the 3.5 framework doesn't fix the problem. Examples Compile fine MyClass myClass = new MyClass(); SortedList <DateTime,MyClass> listOfClasses = new SortedList<DateTime,MyClass> Compile error - Namespace could not be found public SortedList<DateTime,MyClass> ClassList { get; set; } private void DoSomethingToLists(SortedList<DateTime,MyClass> classList) Intellisense has no problem resolving the namespace, only the compiler. Is this a known bug or am I missing something obvious? Will SP1 fix it? I was able to create a new library containing just this class targeting 3.5 and am now able to successfully use this in both 3.5 and 2.0 projects. My guess is that even though I tried to change the target of my original library, since it was still referencing 2.0 projects there was some conflict.

  • How can I build and parse HTTP URL's / URI's / paths in Perl?

    - by Robert S. Barnes
    I have a wget-like script which downloads a page and then retrieves all the files linked in IMG tags on that page. Given the URL of the original page and the the link extracted from the IMG tag in that page I need to build the URL for the image file I want to retrieve. Currently I use a function I wrote: sub build_url { my ( $base, $path ) = @_; # if the path is absolute just prepend the domain to it if ($path =~ /^\//) { ($base) = $base =~ /^(?:http:\/\/)?(\w+(?:\.\w+)+)/; return "$base$path"; } my @base = split '/', $base; my @path = split '/', $path; # remove a trailing filename pop @base if $base =~ /[[:alnum:]]+\/[\w\d]+\.[\w]+$/; # check for relative paths my $relcount = $path =~ /(\.\.\/)/g; while ( $relcount-- ) { pop @base; shift @path; } return join '/', @base, @path; } The thing is, I'm surely not the first person solving this problem, and in fact it's such a general problem that I assume there must be some better, more standard way of dealing with it, using either a core module or something from CPAN - although via a core module is preferable. I was thinking about File::Spec but wasn't sure if it has all the functionality I would need.
