  • Import Hotmail contacts "the right way" ?

    - by AlfaTeK
    I have a website where I want to allow the users to invite their friends, by getting their contacts in hotmail/msn. Google has the google contacts API for these purposes, does MSN publish a similar javascript API? Please note that I do not want to ask the user for their username/password like http://openinviter.com/ . Also, if anyone can provide some tutorials / examples I would appreciate it, as Microsoft docs are usually hard to understand :)

  • IQueryable and lazy loading

    - by Nelson
    I'm having a hard time determining the best way to handle this... With Entity Framework (and L2S), LINQ queries return IQueryable. I have read various opinions on whether the DAL/BLL should return IQueryable, IEnumerable or IList. Assuming we go with IList, then the query is run immediately and that control is not passed on to the next layer. This makes it easier to unit test, etc. You lose the ability to refine the query at higher levels, but you could simply create another method that allows you to refine the query and still return IList. And there are many more pros/cons. So far so good. Now comes Entity Framework and lazy loading. I am using POCO objects with proxies in .NET 4/VS 2010. In the presentation layer I do: foreach (Order order in bll.GetOrders()) { foreach (OrderLine orderLine in order.OrderLines) { // Do something } } In this case, GetOrders() returns IList so it executes immediately before returning to the PL. But in the next foreach, you have lazy loading which executes multiple SQL queries as it gets all the OrderLines. So basically, the PL is running SQL queries "on demand" in the wrong layer. Is there any sensible way to avoid this? I could turn lazy loading off, but then what's the point of having this "feature" that everyone was complaining EF1 didn't have? And I'll admit it is very useful in many scenarios. So I see several options: Somehow remove all associations in the entities and add methods to return them. This goes against the default EF behavior/code generation and makes it harder to do some composite (multiple entity) LINQ queries. It seems like a step backwards. I vote no. If we have lazy loading anyway which makes it hard to unit test, then go all the way and return IQueryable. You'll have more control farther up the layers. I still don't think this is a good option because IQueryable ties you to L2S, L2E, or your own full implementation of IQueryable. Lazy loading may run queries "on demand", but doesn't tie you to any specific interface. I vote no. Turn off lazy loading. You'll have to handle your associations manually. This could be with eager loading's .Include(). I vote yes in some specific cases. Keep IList and lazy loading. I vote yes in many cases, only due to the troubles with the others. Any other options or suggestions? I haven't found an option that really convinces me.

  • How to convert a string into a Point in C#

    - by NateD
    I have a list of strings of the format "x,y". I would like to make them all into Points. The best Point constructor I can find takes two ints. What is the best way in C# to turn "14,42" into new Point(14,42);? I know the Regex for doing that is /(\d+),(\d+)/, but I'm having a hard time turning those two match groups into ints in C#. any help you could offer would be appreciated.

  • What data formats does PowerShell most easily read ?

    - by Jim
    I'm trying to use PowerShell with SharePoint. I'd like my PowerShell scripts to load my SharePoint farm configuration from files rather than either hard coding the configuration in the scripts, or having to pass in the same parameters each time. This the kind of information I need to store. WebFrontEnds: Web1, Web2, Web3 CentralAdmin: Central1 Index: Web1 ContentWebApps: http://user1, http://user2 Does PowerShell easily load this data from CSV, XML, or other formats?

  • Is there a good way of displaying required field indicators when using DataAnnotations in MVC 2?

    - by Jeremy Gruenwald
    I've got validation working with DataAnnotations on all my models, but I'd like to display an indicator for required fields on page load. Since I've got all my validation centralized, I'd rather not hard-code indicators in the View. Calling validation on load would show the validation summary. Has anyone found a good way of letting the model determine what's required, but checking it upon rendering the view, similar to Html.ValidationMessageFor?

  • Consolidating coding styles: Funcs, private method, single method classes

    - by jdoig
    Hi all, We currently have 3 devs with, some, conflicting styles and I'm looking for a way to bring peace to the kingdom... The Coders: Foo 1: Likes to use Func's & Action's inside public methods. He uses actions to alias off lengthy method calls and Func's to perform simple tasks that can be expressed in 1 or 2 lines and will be used frequently through out the code Pros: The main body of his code is succinct and very readable, often with only one or 2 public methods per class and rarely any private methods. Cons: The start of methods contain blocks of lambda rich code that other developers don't enjoy reading; and, on occasion, can contain higher order functions that other dev's REALLY don't like reading. Foo 2: Likes to create a private method for (almost) everything the public method will have to do . Pros: Public methods remain small and readable (to all developers). Cons: Private methods are numerous. With private methods that call into other private methods, that call into... etc, etc. Making code hard to navigate. Foo 3: Likes to create a public class with a, single, public method for every, non-trivial, task that needs performing, then dependency inject them into other objects. Pros: Easily testable, easy to understand (one object, one responsibility). Cons: project gets littered by classes, opening multiple class files to understand what code does makes navigation awkward. It would be great to take the best of all these techniques... Foo-1 Has really nice, readable (almost dsl-like) code... for the most part, except for all the Action and Func lambda shenanigans bulked together at the start of a method. Foo-3 Has highly testable and extensible code that just feels a bit "belt-&-braces" for some solutions and has some code-navigation niggles (constantly hitting F12 in VS and opening 5 other .cs files to find out what a single method does). And Foo-2... Well I'm not sure I like anything about the one-huge .cs file with 2 public methods and 12 private ones, except for the fact it's easier for juniors to dig into. I admit I grossly over-simplified the explanations of those coding styles; but if any one knows of any patterns, practices or diplomatic-manoeuvres that can help unite our three developers (without just telling any of them to just "stop it!") that would be great. From a feasibility standpoint : Foo-1's style meets with the most resistance due to some developers finding lambda and/or Func's hard to read. Foo-2's style meets with a less resistance as it's just so easy to fall into. Foo-3's style requires the most forward thinking and is difficult to enforce when time is short. Any ideas on some coding styles or conventions that can make this work?

  • Can you preload images in a dojo animation.

    - by asynchronous-challenged
    I have a dojo animation object of about 15 images. I'm also using dojo.fx.chain to link them all together. Right before I create all my dojo.fadeIn's and dojo.fadeOut's I added in some basic javascript to preload each image. My question is: Am I doing this the hard way or is there some function/attr I can set in the animation object to do this?

  • How bad is it to use a virtual file system with VMWare? [closed]

    - by user30997
    IT is running a series of VMs that we'd like to see optimized further: if the VMs' are Windows XP, storing their NTFS images out to the virtual disk (ext3) provided by Linux/VMWare, how much of a hit are we taking - as opposed to having a partition of the host hard drive formatted NTFS to eliminate the translation layer and the extra level of operating system IO preparation?

  • Access the path to the app.config programmatically

    - by grenade
    I am looking for a way to programmatically obtain the path to the app.config file from within a Windows Service executable. The build process changes App.config to program-name.exe.config and I could do something like: var configFile = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "program-name.exe.config"); However, I'm looking for some way of obtaining the config file name at runtime that doesn't involve hard coding the exe name into the application. ConfigurationManager has some way of doing it, so it must be possible.
