  • Illegal offset type

    - by BFTrick
    Hello, I am having trouble uploading a file through php. I check the file type at the beginning of the process and I get an error. This is the error I am getting: Warning: Illegal offset type in /balblabla/DBfunctions.inc.php on line 183 This is the printed out $_FILES var Array ( [Picture] = Array ( [name] = JPG.jpg [type] = image/jpeg [tmp_name] = /tmp/phpHlrNY8 [error] = 0 [size] = 192221 ) ) Here is the segment of code I am using that is giving me issues: function checkFile($file, $type) { if( in_array($_FILES[$file]['type'], $type) ){ // <--- LINE 183 return true; }//if return false; } // end checkFile() This is the line of code that calls the function if( checkFile( $_FILES['Picture'], array("image/jpeg") ) == true ){ //do stuff }// end if I have used this piece of code on dozens of websites on my own server so i am guessing that this is some different configuration option. How can i modify my code so that it works on this different server?

  • Google apps API problem with read-only feed?

    - by brandonprry
    Hi all, I am beginning to use the google data api (specifically for the finance app). I can read my portfolio's just fine, so I am authenticating correctly (or so I think). However, when i try and create a portfolio, I get a 'feed is read-only' error. The constructor for the service: public class FinanceService : Service, IService { public FinanceService(string applicationName) : base ("finance", applicationName) { this.RequestFactory = new GDataGAuthRequestFactory("finance", applicationName) { ProtocolMajor = 3 }; } } and saving it is private const string _schema = "http://schemas.google.com/finance/2007"; private const string _feed = "http://finance.google.com/finance/feeds/default/portfolios"; AtomFeed atomFeed = new AtomFeed(new Uri(_feed), this.FinanceService); return this.FinanceService.Insert(atomFeed, this as AtomEntry) as PortfolioEntry; Any idea why the atomFeed would come back ReadOnly? The credentials are legit, and I can get my current portfolios without a problem.

  • aacplus frame alignment problems

    - by Daniel Mošmondor
    I have an application that rips aac+ audio streams, cutting them at every regular interval (i.e. 10 minutes). Sometimes files are playable OK, but sometimes, Windows Media Player just closes when trying to build DirectShow graph. I am using Orban aacplus plugin, and it works under directshow. When I play this file with winamp or vlc, that have it's own aacplus decoding engine, it works fine. However, I need it to work under directshow. Anyway, problematic file is here: http://www.videophill.com/files/00272-20100418100002.aac I know that there is frame alignment error and I confirmed my theory by filling first 256 bytes with 0x00, tried to play it again, and it worked. Is there any info on aacplus frames available on the web, so I can try to find the beginning of the frame manually and cut the rest off?

  • What is a good practice for handling SQL connections within a WCF call?

    - by Rising Star
    Suppose I want to create a (stateless) WCF service with three methods exposed on an endpoint: performSqlOperationA(), performSqlOperationB(), and performSqlOperationC(). Each method inserts data into a SQL database. The way I've seen things done at my office, each method would begin with code to initialize a SqlConnection object. Each method would end with code to safely dispose it. What is a good practice for coding these WCF methods so that the SqlConnection object is initialized and disposed in each method without having to do these things in each method? I know that I can have the connection initialized in the constructor for the class for the WCF methods, but I don't know about disposing it... The calls cannot be wrapped in a using block. One solution I'm familiar with is PostSharp, which allows me to set an attribute which causes specific code to automatically run at the beginning and end of each method call, but it would be greatly preferable to do this with only the .net framework.

  • Where is the best place to put <script> tags in HTML markup?

    - by mipadi
    When embedding JavaScript in an HTML document, where is the best place to put the <script> tags and included JavaScript? I seem to recall that you are not supposed to place these in the <head> section, but placing at the beginning of the <body> section is bad, too, since the JavaScript will have to be parsed before the page is rendered completely (or something like that). This seems to leave the end of the <body> section as a logical place for <script> tags. So, where is the best place to put the <script> tags? (This question references this question, in which it was suggested that JavaScript function calls should be moved from <a> tags to <script> tags. I'm specifically using JQuery, but more general answers are also appropriate.)

  • How can i convert a string into byte[] of unsigned int 32 C#

    - by Miroo
    i have string like "0x5D, 0x50, 0x68, 0xBE, 0xC9, 0xB3, 0x84, 0xFF" i wanna convert it into byte[] key= new byte[] { 0x5D, 0x50, 0x68, 0xBE, 0xC9, 0xB3, 0x84, 0xFF}; i thought about splitting the string by ',' then loop on it and setvalue into another byte[] in index of i string Key = "0x5D, 0x50, 0x68, 0xBE, 0xC9, 0xB3, 0x84, 0xFF"; string[] arr = Key.Split(','); byte[] keybyte= new byte[8]; for (int i = 0; i < arr.Length; i++) { keybyte.SetValue(Int32.Parse(arr[i].ToString()), i); } but seems like it doesn't work i get error in converting the string into unsigned int32 on the first beginning an help would be appreciated

  • How can we make a single dimension array to multidimensional Hierarchical ?

    - by Chetan sharma
    I have an single array of Hierarchical categories. Index of the array is the category_id like:: [8846] => Array ( [category_id] => 8846 [title] => Tsting two [description] => Tsting two [subtype] => categories [type] => object [level] => 2 [parent_category] => 8841 [tags] => new [name] => Tsting two ) each value has its parent_category value, I have around 500 elements in the array, what is the best way to make it. Process i followed: krsort categories array, so that all the child categories are at the beginning, then function makeHierarchical() { foreach($this->categories as $guid => $category) { if($category['level'] != 1) $this->multilevel_categories[$category['parent_category']][$guid] = $category; } } but this is not working, it does it only for first level. Can someone point out me the error.

  • Create facebook object each and every time?

    - by oshirowanen
    I have a login page which will log a user into my webapp based on their facebook login details. I then create a session to remember who they are. What I want to know is, should I be creating and/or checking the facebook credential on every single page of my webapp, or should I simply use the session I create at the beginning to login? For example, once they have logged in, I would like to allow them to post a message onto their own facebook wall from my app. Should I check the login credentials before they can post by recreating the facebook object, or should I simply use the stored login details already in my session and use that to post to their facebook wall?

  • Managing Data Prefetching and Dependencies with .NET Typed Datasets

    - by Derek Morrison
    I'm using .NET typed datasets on a project, and I often get into situations where I prefetch data from several tables into a dataset and then pass that dataset to several methods for processing. It seems cleaner to let each method decide exactly which data it needs and then load the data itself. However, several of the methods work with the same data, and I want the performance benefit of loading data in the beginning only once. My problem is that I don't know of a good way or pattern to use for managing dependencies (I want to be sure I load all the data that I'm going to need for each class/method that will use the dataset). Currently, I just end up looking through the code for the various classes that will use the dataset to make sure I'm loading everything appropriately. What are good approaches or patterns to use in this situation? Am I doing something fundamentally wrong? Although I'm using typed datasets, this seems like it would be a common situation where prefetching data is used. Thanks!

  • req.getParameter returns values wrong character encoding

    - by coder247
    I'm trying to get values from a JSP using getParameter which includes ü,é,à etc. But get wrong values in servlet. I've checked the content type with firebug and found that Content-Type text/html;charset=UTF-8 checked the POST section with firebug and found the correct value there, when I try to access it in servlet it is wrong. Gives ö instead of ö req.getCharacterEncoding(); returns null. Tried with setting req.setCharacterEncoding("UTF-8"); at the beginning of servlet but didn't help.

  • How do I clear the contents of a file using c?

    - by Eddy
    I'm writing some code so that at each iteration of a for loop it runs a functions which writes data into a file, like this: int main() { int i; /* Write data to file 100 times */ for(i = 0; i < 100; i++) writedata(); return 0; } void writedata() { /* Create file for displaying output */ FILE *data; data = fopen("output.dat", "a"); /* do other stuff */ ... } How do I get it so that when I run the program it will delete the file contents at the beginning of the program, but after that it will append data to the file? I know that using the "w" identifier in fopen() will open a new file that's empty, but I want to be able to 'append' data to the file each time it goes through the 'writedata()' function, hence the use of the "a" identifier.

  • When to stop following the advice of static code analysis?

    - by bananeweizen
    I do use static code analysis on a project with more than 100.000 lines of Java code for quite a while now. I started with Findbugs, which gave me around 1500 issues at the beginning. I fixed the most severe over time and started using additional tools like PMD, Lint4J, JNorm and now Enerjy. With the more severe issues being fixed, there is a huge number of low severity issues. How do you handle these low priority issues? Do you try fixing all of them? Or only in newly written code? Do you regularly disable certain rules? (I found that I do on nearly any of the available tools). And if you ignore or disable rules, do you document those? What do your managers say about "leaving some thousand low priority issues not fixed"? Do you use (multiple) tool specific comments in the code or is there any better way?

  • PHP validating integers

    - by Mikk
    Hi, I was wondering, what would be the best way to validate an integer. I'd like this to work with strings as well, so I could to something like (string)+00003 - (int)3 (valid) (string)-027 - (int)-27 (valid) (int)33 - (int)33 (valid) (string)'33a' - (FALSE) (invalid) That is what i've go so far: function parseInt($int){ //If $int already is integer, return it if(is_int($int)){return $int;} //If not, convert it to string $int=(string)$int; //If we have '+' or '-' at the beginning of the string, remove them $validate = ($int[0] === '-' || $int[0] === '+')?substr($int, 1):$int; //If $validate matches pattern 0-9 convert $int to integer and return it //otherwise return false return preg_match('/^[0-9]+$/', $validate)?(int)$int:FALSE; } As far as I tested, this function works, but it looks like a clumsy workaround. Is there any better way to write this kind of function. I've also tried filter_var($foo, FILTER_VALIDATE_INT); but it won't accept values like '0003', '-0' etc.

  • in-place permutation of a array follows this rule

    - by Mgccl
    Suppose there is an array, we want to find everything in the odd index, and move it to the end. Everything in the even index move it to the beginning. The relative order of all odd index items and all even index items are preserved. Suppose the values of the array, a[i] = i, n is even. Then we have. 0,1,2,3,4,5,...,n-1 after the operation 0,2,4,6,...,n-2,1,3,5,7,...,n-1 Can this be done in-place and in O(n) time?

  • RewriteRule - Doesn't work on live site - subfolder to new domain

    - by eb_Dev
    I have the following rule on my local dev site and it works fine: RewriteCond %{HTTP_HOST} ^localhost$ RewriteRule ^subdomains/example.com(.*) http://www.example.com$1 [R=301,L] However when I change it to: RewriteCond %{HTTP_HOST} ^www.domain.com$ RewriteRule ^subdomains/example.com(.*) http://www.example.com$1 [R=301,L] and upload it to my live site it doesn't work, if i change the rule to: RewriteCond %{HTTP_HOST} ^www.domain.com$ RewriteRule ^subdomains/(.*) http://www.example.com$1 [R=301,L] the rule functions as expected and directs an url beginning with www.domain.com/subdomains/ to www.example.com/. Does anyone know what is going on here? Thanks for you help.

  • How do I link a Navigation Menu to an already existing Sitemap

    - by JMK
    I am just beginning my journey into web development and I have a very basic question, but I am none the less stumped. I have setup a new ASP.NET Empty Web Application. In this application, I have created a few *.aspx pages and a sitemap called 'Web.sitemap'. I have placed a SiteMapPath control onto my Master page and, with no further configuration, this detected my Web.sitemap and displays the location of the page on any *.aspx page which derives from the master page. However, whenever I add a Navigation Menu, this doesn't happen. When I bring up the Menu Tasks dialogue box, I can't select this from the Choose Data Source dropdown, my only option is to choose <New data source...> which brings up the Data Source Configuration Wizard, and from this I can create a new Site Map, however I want to use the already existing one. How do I go about this? Thanks

  • Problems with Ruby "||" "or"?

    - by Kevin
    Beginning Ruby Question: I'm trying to see if a string variable's contents is either "personal" "email" or "password". I'm trying: if params[:action] == "password" || "email" || "personal" foo else don't foo end But that doesn't work and returns strange results, and using IRB to play around with "or" statements I have no idea why the following happens: irb(main):040:0> a = "email" => "email" irb(main):041:0> a == "password" || "email" => "email" irb(main):042:0> a == "email" || "password" => true I just want something that if any of the 3 variables are true no matter what order they are in it returns true, if not it returns false. Anyone want to help this n00b out?

  • Objective-C NSString Assignment Problem

    - by golfromeo
    In my Cocoa application, in the header file, I declare a NSString ivar: NSString *gSdkPath; Then, in awakeFromNib, I assign it to a value: gSdkPath = @"hello"; Later, it's value is changed in the code: gSdkPath = [NSString stringWithString:[folderNames objectAtIndex:0]]; (the object returned from objectAtIndex is an NSString) However, after this point, in another method when I try to NSLog() (or do anything with) the gSdkPath variable, the app crashes. I'm sure this has something to do with memory management, but I'm beginning with Cocoa and not sure exactly how this all works. Thanks for any help in advance.

  • Join unrelated tables through a second level connected table

    - by Andy M
    Hello! I have two tables of activities on a page: Views & Comments. Views id timestamp project_id user_id page_id Comments id timestamp project_id user_id page_id comment Pages id project_id title Now pages are related to projects: Projects id account_id title I am trying to create a summary page that combines views and comments ordered by time (so that the most recent views/comments are at the beginning, grouped by projects. Also, only projects for a specific account. So the result could potentially be: Project 1 View 5 (June 20th) View 4 (June 18th) Comment 5 (June 15th) Comment 4 (June 14th) Comment 3 (June 12th) Project 3 View 3 (June 10th) View 2 (June 8th) Comment 2 (June 7th) Project 2 View 1 (June 5th) Comment 1 (June 4th) If you could help with how to do this using SQL (or even doctrine) that would be awesome. Thank you.

  • Would the world be a better place if there were only one programming language?

    - by Simon
    Well, perhaps not the world, but would it encourage more-re-use, less replication of basic code, or at least an uplift in what is considered basic code, more time advancing the application science and a greater encouragement to share, a more advanced base of understanding for new programmers, since the language could be taught ubiquitously and patterns of teaching would have emerged which were optimised for students learning etc etc? I think all of those things would make the programming world better and would probably have significant commercial benefit too. This is definitely not a religious debate about which language is best, and is predicated on the notion of some super-being having designed the perfect language to start with, which was improbable, but it strikes me that if, from the beginning, there were only a single programming language we may be further along in terms of the evolution of the software industry and software science. And although it is now impossible, if you buy some or all of these assertions is there an argument for standardising on a single language for the future so we can accelerate our collective progress rather than all of us re-inventing some part of the same wheel and consigning our children to the same fate?

  • is PHP itself transforming into a framework or big library?

    - by Elzo Valugi
    At the beginning PHP was a scripting language. But after the introduction and improvement of OOP I see more and more objects added to the core. They started with SPL which grew a lot, now we have DOMDocument family, DateTime family which should be part of PECL, Pear or Zend Framework or implemented by each one of us. Shouldn't be php only for build-in functions and all these objects passed to something else? Example. DateTime class is part of the core and I see it very similar with Zend_Date.

  • What's causing “Session state has created a session id, but cannot save it because the response was

    - by mike nelson
    I'm getting this fault intermittently. I found this link which summarises fairly well what I was able to find on the Google: http://www.wacdesigns.com/2009/02/03/session-state-has-created-a-session-id-but-cannot-save-it-because-the-response-was-already-flushed-by-the-application/ Basically it says you can try setting the web config setting DisplayWhenNewSession, or try kicking the session state thing into life by getting the Session.SessionID in the Session_OnStart. But does anyone: a) have an explanation for this or even better, b) have a tried and tested fix I realise that I can't flush the response after doing anything that would affect the http response header. If I did this it would cause an error every time but this is intermittent. The SessionID should surely be created by ASP.NET at the beginning of the page response automatically, before anything in the ASPX page or the Page_Load (which is where all my flushes are called).

  • Resharper: how to force introducing new private fields at the bottom of the class?

    - by Igor Brejc
    Resharper offers a very useful introduce and initialize field xxx action when you specify a new parameter in a constructor like: Constructor (int parameter) The only (minor) nuisance is that it puts the new field at the beginning of the class - and I'm a fan of putting private parts as far away as possible from the prying eyes of strangers ;). If, however, you already have some private fields in the class, Resharper will put the new field "correctly" (note the quotes, I don't want to start a flame war over this issue) next to those, even if they are at the end of the class. Is there a way to force Resharper to always put new fields at the end of the class? UPDATE: OK, I forgot to mention I know about the "Type Members Layout in Options" feature, but some concrete help on how to modify the template to achieve fields placement would be nice.
