  • C Structure Pointer Problem

    - by Halo
    I have this struct; #define BUFSIZE 10 struct shared_data { pthread_mutex_t th_mutex_queue; int count; int data_buffer_allocation[BUFSIZE]; int data_buffers[BUFSIZE][100]; }; and I want to allocate one of the data_buffers for a process, for that purpose I execute the following function; int allocate_data_buffer(int pid) { int i; for (i = 0; i < BUFSIZE; i++) { if (sdata_ptr->data_buffer_allocation[i] == NULL) { sdata_ptr->data_buffer_allocation[i] = pid; return i; } } return -1; } but the compiler warns me that I'm comparing pointer to a value. When I put a & in front of sdata_ptr it calms down but I'm not sure if it will work. Isn't what I wrote above supposed to be true?

  • Substituting variables in a loop?

    - by jksl
    I am trying to write a loop in R but I think the nomenclature is not correct as it does not create the new objects, here is a simplified example of what I am trying to do: for i in (1:8) { List_i <-List colsToGrab_i <-grep(predefinedRegex_i, colnames(List_i$table)) List_i$table <- List_i$table[,predefinedRegex_i] } I have created 'predefinedRegex'es 1:8 which the grep should use to search The loop creates an object called "List_i" and then fails to find "predefinedRegex_i". I have tried putting quotes around the "i" and $ in front of the i but these do not work. Any help much appreciated. Thank you.

  • Please explain this php expression "!$variable"

    - by DogBot
    What does an exclamaton mark in front of a variable mean? And how is it being used in this piece of code? EDIT: From the answers so far I suspect that I also should mention that this code is in a function where one of the parameters is $mytype ....would this be a way of checking if $mytype was passed? - Thanks to all of the responders so far. $myclass = null; if ($mytype == null && ($PAGE->pagetype <> 'site-index' && $PAGE->pagetype <>'admin-index')) { return $myclass; } elseif ($mytype == null && ($PAGE->pagetype == 'site-index' || $PAGE->pagetype =='admin-index')) { $myclass = ' active_tree_node'; return $myclass; } elseif (!$mytype == null && ($PAGE->pagetype == 'site-index' || $PAGE->pagetype =='admin-index')) { return $myclass; }`

  • When loading shopping cart in Magento with a new Payment module, I get an error I haven't been able

    - by Joseph
    I am trying to add a new payment module into Magento. However, even after commenting out the vast majority of the code, I still get the following error: Fatal error: Call to a member function isAvailable() on a non-object in /var/www/html/app/code/core/Mage/Payment/Helper/Data.php on line 71 I am using Magento 1.4.0.1, and have disabled the cache. I even emptied the cache several times just in case. The only code currently not commented out is based on the tutorials here and here. The error occurs when the cart is loaded either from the administration area or the front end. Is there anyone out there that has run into a similar issue? I would post code, but I am not sure what needs to be posted. Thanks for the assistance.

  • Share Link - Perform action in background

    - by Justin
    I have an application that will accept URLs from the built in web browser via the "Share page" menu item. I'm using the send intent and it works just fine. However, I'd like to accept a URL and process it in the background without bringing my application to the front. I don't want the user to have to actually leave the web browser. It will notify the user it has finished processing the URL with a Toast message. I'm just not sure what type of activity should be used for this. A good example of this behavior is the "Read Later" instapaper application in the android market. Any help would be greatly appreciated.

  • How to use anonymous types with Netflix OData API

    - by obautista
    If I create this collection: IEnumerable<_TITLE> _titles = null; How can I set the result set from Netflix in this expression: _titles = from t in Titles where t.Id == "ApUFq" select new {t, t.Cast} I am getting: Cannot implicitly convert type 'System.Linq.IQueryable' to 'System.Collections.Generic.IEnumerable<_Title'. An explicit conversion exists (are you missing a cast?) I understand it's because I am using an anonymous type. _TITLE is a custom complex object I create that exposes a subset of Netflix properties. If I add "_TITLE" in front the of the "new" it says that my object does not implement IENUMBERABLE. If then _TITLE implements IENUMBERABLE, it says _TITLE does not contain a definition for ADD and still getting conversion error. Basically, I want to set the _TITLE properties with the data returned from Netflix. I have defined _TITLE to contain the fields I need, plus a collection of PERSON (for Cast).

  • How do I access the ASP.NET Configuration Tool when a site is live? This is ASP.NET MVC.

    - by Mike Marks
    I was wondering if it's possible to access the ASP.NET Configuration Tool once a site is live. To be able to create and edit users and roles is obviously very important, and from what I've been reading, once a site is deployed, the Configuration Tool is no longer accessible. If this is the case, HOW do I add users, etc.? By the way, I found a User Management plugin which brings a lot of the Configuration Tool's capabilities to the front end of a User Management section of the deployed website, but it DOES NOT offer the capability to add a new user. Help??? Thanks!!

  • Is SQL Server Compact *ever* OK to use on a web server?

    - by Troy
    I'd like to host a personal database for about 500 people (1 database per person) on my web server. A person could possibly share their database with a friend or two. On my web server, I'd have some web services, perhaps for doing synchronization, and maybe even an ASP.NET Web Forms front end to the database. If I restart my IIS web server, would this likely cause database corruptions? Would this be expected to perform ok? If not Compact, should I instead use SQL Express and create a database in SQL Server for each of my 500 people?

  • nginx + ssi + remote uri access does not work

    - by stunti
    I have a setup where my nginx is in front with apache+PHP behind. My PHP application cache some page in memcache which are accessed by nginx directly except some dynamic part which are build using SSI in Nginx. The first problem I had was nginx didnt try to use memcache for ssi URI. <!--# include virtual="/myuser" --> So I figured that if I force it to use a full URL, it would do it. <!--# include virtual="http://www.example.com/myuser" --> But in logs file (both nginx and apache) I can see that a slash has been added at the beginning of the url http ssi filter "/http://www.example.com/myuser" In the source code of the SSI module I see a PREFIX that seems to be added, but I can really tell if I can disable it. Anybody got this issue? Nginx version : 0.7.62 on Ubuntu Karmic 64bits Thanks a lot

  • Can I assume Flash and PHP will generate the same floating point numbers?

    - by Fragsworth
    In a multiplayer game I'm developing, we have a few values that are floating point numbers. The back-end (in PHP) and the front-end (in Flash) occasionally perform the same calculations on these numbers, to minimize communication. I am currently making sure that both sides are using 64-bit doubles, but am I safe to assume that all calculations will be the same? For instance, what about string to float conversion - should I worry about Flash having a potentially different implementation as PHP? (If this happens, our game will go out of sync - the client will think it is in one state while the server is in another) With some testing, it appears to be the same, but I'm just not sure. Can someone clarify this for me?

  • Joomla article not showing in the frontend but its visible in administrative part.

    - by user248674
    I have a very big article to be put into our joomla site. At first I was getting "Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 285487 bytes) in..." . But then I increased the memory_limit in php.ini . And I was able to create the article. Now I can view the article by logging into backend. But the article is not at all visible in the front end. If I click on the menu item pointing to that article, all I can see is a blank page with nothing in it. All other articles in the site are visible properly. Any idea? ps: I have enabled the error reporting to maximum, also ran the site in debugging mode. But saw nothing unusual.

  • Querying my JPA provider (Hibernate) for a collection of <Id,Name> of an entity

    - by Ittai
    Hi, I have an entity which looks something like this: Id (PK) Name Other business properties and associations... I have the need for my DAL (JPA with hibernate as provider) to return a list of the entities which correlate to some constraints (or just return them all) but instead of returning the entities themselves I'd like to receive only the Id and the Name properties. I know this can be achieved with HQL/SQL (something like: select id,name from entity where...) but I don't want to go down that road. I was thinking of somehow defining the pair a compositioned part of the entity and thought that might help me but I'm not sure that's "legal" as the Id is the PK. The logic for this scenario is to have a textbox which asynchronously queries the web-service (and through it the DAL) for the relevant entities and once an entity is selected then it is loaded as a whole and shipped to the front-end. Would appreciate any feedback, Ittai

  • How do I make my browser brute force an input field?

    - by user210904
    Hi, There's a website I frequent that gives codes such as GD??Q-TPY32-TPTT3-9CM9P-F2QMQ and hints that the ?? is a number and a letter. If you're the first to unlock the code you can redeem the modest prize. So the obvious way to solve this problem is to brute-force the code. But obviously I don't want to sit in front of the computer for an hour to manually input all 10 * 26 combinations. Is there a way for me to tell my browser to input these codes (assume that each 5-character block is an individual text field). Or is there a special browser that enables some sort of macro-type feature? Thanks.

  • Tips for improving performance of DB that is above size 40 GB (Sql Server 2005) and growing monthly

    - by HotTester
    The current DB or our project has crossed over 40 GB this month and on an average it is growing monthly by around 3 GB. Now all the tables are best normalized and proper indexing has been used. But still as the size is growing it is taking more time to fire even basic queries like 'select count(1) from table'. So can u share some more points that will help in this front. Database is Sql Server 2005. Further if we implement Partitioning wouldn't it create a overhead ? Thanks in advance.

  • What are the alternatives for Java authentication?

    - by Crusader
    Preferably something that integrates well with a Flex front end. Yes the Spring Security guys say this is possible, but all examples seem to use legacy jsp tag libraries making them half useless as examples. I don't want to spend a month setting up and learning how to use a security tool. I would like a tool which supports using annotations (@RolesAllowed etc), MINIMAL XML, and 'remember-me' features (not cookie based). Apache Shiro seems to support Flex/Silverlight/Swing as well but I'd like to know if there are any other alternatives that are NOT container specific.

  • Joining two tables (through a link), one which may yield multiple rows, together into one result.

    Lets say I've got a table listing car brands or models: Cars: Id | Brand ----------- 1 | BMW 2 | Audi 3 | Volvo And I've also got another table which links features.

  • Safe way to support hosting files from asp.net mvc site

    - by ooo
    i have an asp.net-mvc site where users can add content and links and the data gets saved in a database. They now want the ability to upload attachments to pages and i wanted to figure out a few things: I have upload code that will upload files (pdfs, images, etc) but i wanted to see where i should be storing them. should i store them outside the website directory structure ? Is there any file types that i should be concerned with storing. I would basically have a file picker on the front end.

  • A depth (z-index) nightmare.

    - by JCOC611
    The best way to illustrate this question is with...a Fiddle! Before you visit the fiddle, notice there is text behind the grayest element, which is on top of a light gray element that has a border. There is a main wrapping div (root), and two wrapping divs inside (wrap1 and wrap2). The problem here is that I need the content of wrap2 (highlight) to be behind the content of wrap1 (text), but in front of the background of the root. This, however, must not change: The HTML, the elements and wraps should be left untouched. Excluding the order of wrap1 and wrap2 inside root. The highlight div must keep the absolute positioning. Styling highlight with background-color is not an option, the existence of highlight is a must. PS: the italics reference the id's of <div>s in the fiddle example, for whomever was too lazy to visit it.

  • Is node.js ready for production use?

    - by Simon Wentley
    Starting a new project. It's basically a blogging/commenting system. We're considering node.js as the back end server. Is node.js ready for this sort of thing or is it too early and experimental? We need HTTPS and gzip compression - perhaps a front end nginx server could provide this? What's missing from node.js that would make developing a web app difficult? From a production ready perspective, we're wondering if it is stable enough for building a commercial app on top of. Thanks

  • Strange problem with ie6 messing up layout, and fixing byitself some time after loading

    - by 0al0
    We have a big ie6 layout problem with a newly launched website: in the header in our homepage, we have a coda-slider, and apparently its messing upt the wole layout of the front page. I have been looking at float and height problems but cannot seem to solve it. Also, the most strange part is that if you wait a while after loading, the layout "fixes itself". Help! The url is the following (without the spaces, sorry) w w w . r e - c r e a r t . c o m Edit: update, it sounds crazy, but if you press control and use the mouse wheel (as if you were zooming in /out in a modern browser, although ie6 doesnt do that) the layout fixes as well. Please help, I am going crazy.

  • event vs thread programming on server side.

    - by AlxPeter
    We are planning to start a fairly complex web-portal which is expected to attract good local traffic and I've been told by my boss to consider/analyse node.js for the serve side. I think scalability and multi-core support can be handled with an Nginx or Cherokee up in the front. 1) Is this node.js ready for some serious/big business? 2) Does this 'event/asynchronous' paradigm on server side has the potential to support the heavy traffic and data operation ? considering the fact that 'everything' is being processed in a single thread and all the live connections would be lost if it got crashed (though its easy to restart). 3) What are the advantages of event based programming compared to thread based style ? or vice-versa. (I know of higher cost associated with thread switching but hardware can be squeezed with event model.) Following are interesting but contradicting (to some extent) papers:- 1) http://www.usenix.org/events/hotos03/tech/full_papers/vonbehren/vonbehren_html 2) http://pdos.csail.mit.edu/~rtm/papers/dabek:event.pdf

  • Is it possible get the functionality of namespaces inside a class?

    - by CowKingDeluxe
    I have the following code: Public Class Form1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Class What I would like to do is be able to separate the code, similar to the following (which obviously doesn't work): Public Class Form1 Namespace Step1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function End Namespace Namespace Step2 Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Namespace End Class I would like the functionality of namespaces inside of a class, as in something that would let me call Step2.Execute() instead of having to put Step2_ in front of a whole bunch of functions. I don't want to have to create separate classes / modules for step1, step2, etc. Is there a way that I can accomplish namespace functionality from inside a class?

  • Loading jQuery with Tapestry 5

    - by American Yak
    Okay, so I'm not a Java guy, but I work with loads of them. We generally load Prototype with Tapestry 5, as Tapestry was built on this javascript library. As a UI/front end developer/engineer, I know the awesomeness of jQuery and the lack of prototype therein. (Feel free to debate that elsewhere -- this ticket doesn't concern that question, ha.) I've been curious for some time if it's possible to port jQuery into Tapestry instead of Prototype -- as in completely removing Prototype and Scriptaculous -- I realize it kind of defeats the purpose of the already bundled Prototype, but I wanted other opinions on the matter. Thanks.
