    - by davemackey

But, right now it shows all my database tables with the db column names - which aren't always the most friendly (e.g. address_line_1). How can I got about giving these more friendly column titles that will display to the end user?

  • How much memory does a hashtable use?

    - by Michael
    Would a hashtable/hashmap use a lot of memory if it only consists of object references and int's? As for a school project we had to map a database to objects (that's what being done by orm/hibernate nowadays) but eager to find a good way not to store id's in objects in order to save them again we thought of putting all objects we created in a hashmap/hashtable, so we could easily retrieve it's ID. My question is if it would cost me performance using this, in my opinion more elegant way to solve this problem.

  • Using Entity Framework V4 - Mapping Stored Procedures with XML output

    - by ericwahner
    I have been attempting to implement the Entity framework into my project and unfortunately it seems like mapping an XML result set from SQL is not something that is supported. I also have issues with returning multiple result sets, though I understand that the EFExtensions was created to try to mitigate that issue. Is there a way to take a FOR XML EXPLICIT result from a SQL Stored Procedure and map it using the Entity Framework?

  • Main point of Application Delegate class

    - by ahmet732
    What's the main point behind putting variables and method signatures inside ApplicationDelegate.h in Objective-C ? By doing this, all those methods and variables are seen by another view controller classes? Is that the point? And also: is there only one application delegate class inside each project?

  • One-to-One relation classes

    - by SeyZ
    I want to have a class named ProjectDirectory and a class named MetaDirectory. Each project has a MetaDirectory which contains some meta data. Is it the good way to write the classes like this: class ProjectDirectory(object): def __init__(self, directory=None): self.directory = directory self.meta_directory = MetaDirectory(self) def __repr__(self): return self.directory class MetaDirectory(object): def __init__(self, project_directory=None): self.project_directory = project_directory self.directory = "%s/.meta/" % project_directory ProjectDirectory has a reference to MetaDirectory and MetaDirectory has a reference to ProjectDirectory. Is there an other solution or this solution is good ?

  • Localization of UI

    - by Nadeem
    I am working on localization project and when i change the language the UI gets disturbed because some translations are large. For example say there is button with text "Select All". But when this is localized in french it reads as "Sélectionner tout". That is larger than Select All and hence the gui gets affected. Is there any way to localize the gui as well.
