  • Loading a entity IDs CSV column as hydrated entities in NHibernate

    - by James L
    I have a number of database table that looks like this: EntityId int : 1 Countries1: "1,2,3,4,5" Countries2: "7,9,10,22" I would like to have NHibernate load the Country entities identifed as 1,2,3,4,5,7,9 etc. whenever my EntityId is loaded. The reason for this is that we want to avoid a proliferation of joins, as there are scores of these collections.

  • Getting started with unit testing in VS2010?

    - by Herb Caudill
    I'm new to both unit testing and Visual Studio 2010 (just upgraded from 2008). I'm interested in using VS2010's new built-in unit testing tools, but would like to get the lay of the land first. I haven't been able to find any resources or tutorials on unit testing with VS2010 specifically - has anyone found a good walk-through? I'm also open to persuasion that we should stick with NUnit or the like, if anyone knows a reason to avoid the built-in tools.

  • No IO exception reported for socket operation when the interface is removed

    - by user352536
    The wifi network is connected, the application setup a socket connection and exchange data with the remote server. But when turn off the wifi, the inteface is removed, while socket operation read/write on this socket is still like normal, no any IO exception reported. The application has to do some extra checking to avoid waiting for the data forever. Is this the normal case for Android design? Is there any plan to fix it?

  • Avoiding dependency carrying

    - by dotnetdev
    When coding, I often come across the following pattern: -A method calls another method (Fine), but the method being called/callee takes parameters, so in the wrapping method, I pass in parameters. Problem is, this dependency carrying can go on and on. How could I avoid this (any sample code appreciated)? Thanks

  • decorating a function and adding functionalities preserving the number of argument

    - by pygabriel
    I'd like to decorate a function, using a pattern like this: def deco(func): def wrap(*a,**kw): print "do something" return func(*a,**kw) return wrap The problem is that if the function decorated has a prototype like that: def function(a,b,c): return When decorated, the prototype is destroyed by the varargs, for example, calling function(1,2,3,4) wouldn't result in an exception. Is that a way to avoid that? How can define the wrap function with the same prototype as the decorated (func) one? There's something conceptually wrong?

  • Stored Queries?

    - by phpeffedup
    Is it considered crazy to store common SQL queries for my web app in a database for use in execution? Or is that common practice? Or is it impossible? My thinking is, this way, I avoid hard-coding SQL into my application files, and add another level of abstraction. Is this crazy? Is this what a stored procedure is? Or is that something else?

  • Method parameters confusion

    - by elec
    Often time methods take more than 3 parameters which are all of the same type, eg. void mymethod (String param1, String param2, String param3) then it's very easy for the client to mix up the parameters orders, for instance inverting param1 and param2: mymethod (param2, param1, param3); ...which can be the cause of much time spent debugging what should be a trivial matter. Any tips on how to avoid this sort of mistake (apart from unit tests) ?

  • iPhone SDK development obj-C vs interface builder

    - by Amy
    I'm new to the iOS platform. I'm not clear on the purpose of the interface builder. It looks like I can avoid using it entirely and just write all the code in objective c. am I right? is there anything that IB can do but obj-c cannot? It reminds me of visual basic 6.

  • Which user account to assign as owner when attaching an SQL Server database?

    - by FreshCode
    This is a simple database security & performance question, but I've always used either a special user (eg. mydbuser), or Windows' built-in NETWORK SECURITY account as the owner when attaching databases to my SQL Server instances. When deploying my database to a production server, is there a specific user I should stick to or avoid? I would think that using an account with a set password could open the database up to a potential security issue.

  • Can I Force A ASP.Net Website to Show Time in A Specific Time Zone?

    - by KevDog
    I have a client request that all times be displayed in Pacific Time Zone, regardless of client settings. I'd like to avoid a scenario where I have to call a function for every time display and instead have a single point where I can make the switch. I'm thinking a custom culture might do the trick, but I wanted to ask before I set off down a potentially blind alley (or miss something trivially easy).

  • How do I escape backslashes in JSON?

    - by peteb
    I am using Firefox's native JSON.parse() to parse some JSON strings that include regular expressions as values, for example: var test = JSON.parse('{"regex":"/\\d+/"}'); The '\d' in the above throws an exception with JSON.parse(), but works fine when I use eval (which is what I'm trying to avoid). What I want is to preserve the '\' in the regex - is there some other JSON-friendly way to escape it?

  • how to store data crawled from website

    - by Richard
    I want to crawl a website and store the content on my computer for later analysis. However my OS file system has a limit on the number of sub directories, meaning storing the original folder structure is not going to work. Suggestions? Map the URL to some filename so can store flatly? Or just shove it in a database like sqlite to avoid file system limitations?

  • Rails SQL injection?

    - by yuval
    In Rails, when I want to find by a user given value and avoid SQL injection (escape apostrophes and the like) I can do something like this: Post.all(:conditions => ['title = ?', params[:title]]) I know that an unsafe way of doing this (possible SQL injection) is this: Post.all(:conditions => "title = #{params[:title]}") My question is, does the following method prevent SQL injection or not? Post.all(:conditions => {:title => params[:title]})

  • Neat way of calling InvokeRequired and Invoke

    - by ho
    I seem to remember seeing some neat way of calling InvokeRequired and Invoke to avoid repeating too much code in every event handler but I can't remember what that was. So does anyone know a neat way of writing that code? Preferably for VB.Net 2005.
