  • Trouble echoing data - data being converted to 0

    - by Haraldo
    Hi, I feel this is something to do with my httpd setup for apache. I'm using mod_rewrite if that helps but I think that only effects the url. It seems when I output some data such as: $sMessage = 'Error'; echo $sMessage; It works fine but when I do this: $sMessage = 'Error'; echo ''+$sMessage+''; It returns 0. Very odd!

  • MySQL: LOAD DATA reclaim disk space after delete

    - by Michael
    I have a DB schema composed of MYISAM tables, i am interested to delete old records from time to time from some of the tables. I know that delete does not reclaim the memory space, but as i found in a description of DELETE command, inserts may reuse the space deleted In MyISAM tables, deleted rows are maintained in a linked list and subsequent INSERT operations reuse old row positions. I am interested if LOAD DATA command also reuses the deleted space? UPDATE I am also interested how the index space reclaimed?

  • Core data fetch only returns unique managed objects

    - by JK
    I execute a core data fetch which specifies a predicate as follows: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"identifier IN %@", favoritesIDs]; When there are duplicate items in the favoriteIDs array, the fetch request only returns 1 managed object. How can I ensure that more than one instance is fetched? Thank you.

  • Fast data structure for small sets

    - by thr
    I'm in need for a data structure that can handle small sets (10-20 strings, at most 50, of varying length) very fast. False positives is ok, but false negatives are not. The last requirement makes bloom filters seem like a good fit, but I'm not sure about their speed, any other recommendations?

  • RIA Services and Entity Framework POCOs

    WCF RIA Services contains a special domain service for entity framework which will automatically be used if you use the Domain Service template in Visual Studio. This winter I tried the template with a few projects. One of them had EntityObjects and the other had POCO entities. The EntityObjects worked great, but the POCO entities didn’t work at all. The bulk of the problems were based on the fact that the EntityDomainService used methods from the first version of Entity Framework that relied...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Restoring and passing data to an already running instance of a .NET application

    - by mtranda
    The goal is to have an application that runs in the system tray and can either accept user input from its actual GUI (which isn't the actual issue) OR accept command line parameters (that would actually be done via a context menu in windows explorer). Now, while I'm aware that the command line parameters are not exactly possible once the application has started, I need a way to pass data to the already running application instance via some form of handler. I'm thinking maybe define and raise some sort of event? Thanks in advance.

  • Collision free hash function for a specific data structure

    - by Max
    Is it possible to create collision free hash function for a data structure with specific properties. The datastructure is int[][][] It contains no duplicates The range of integers that are contained in it is defined. Let's say it's 0..1000, the maximal integer is definitely not greater than 10000. Big problem is that this hash function should also be very fast. Is there a way to create such a hash function? Maybe at run time depending on the integer range?

    - by wgpubs
    Is it possible to do mass updates on a given entity in Core Data? Given an Person entity for example, can I do something like this: Person.update(@"set displayOrder = displayOrder + 1 where displayOrder > 5") Or is my only option to fetch all the entities needed and then loop through and update them individually???

  • Data Structure Used For SMS Messages In Android

    - by Greenhouse Gases
    Does anybody know what data structures are used to the store messages in an SMS client app, and whether there is an existing API for this. I was perhaps looking at implementing a link list for the purpose but if the work has already been done in an API then perhaps it would be unnecessary to commit time to the task that could be spent programming other parts. Many thanks
