  Huge project tons of classes and directories. Do I make my unit test project mirror these directories or do I put them all at the root directory? Somewhat annoying to have to make directory changes and class name changes twice.

• Use textbox value on submit as a query string variable

  - by Eric

  How would I take a text box value and use it in the query string on submit? I'd like it to start as this, /News?favorites=True and end up something like this after the user enters in a search and clicks search. /News?query=test&favorites=True The controller action looks like this public ActionResult Index(string query,bool favorites) { //search code } This question is something close to what I'd like to do, but I'd like to use the query string and maintain the existing values in the query string. Thanks.

• Delphi and Outlook TaskItem: How to know if DueDate is empty?

  - by Steve

  This seems like a no-brainer but I couldn't find anything on it. How do I detect if a date variant in Outlook is "empty"? For example TaskItem.DueDate - the duedate is not necessarily filled. If it's not filled Outlook returns "4501.01.01." - I can test for this value, but this just doesn't seem "elegant" enough. Thanks!

• How to get number of entries in a Lua table?

  - by romkyns

  Sounds like a "let me google it for you" question, but somehow I can't find an answer. The Lua # operator only counts entries with integer keys, and so does table.getn: tbl = {} tbl["test"] = 47 tbl[1] = 48 print(#tbl, table.getn(tbl)) -- prints "1 1" count = 0 for _ in pairs(tbl) do count = count + 1 end print count -- prints "2" How do I get the number of all entries?

• How do I verify my EF4 Code-Only mappings?

  - by Tomas Lycken

  In NHibernate, there is a method doing something like ThisOrThat.VeryfyMappings() (I don't know the exact definition of it since it was a while ago I last tried NHibernate...) I recall seeing a blog post somewhere where the author showed how to do some similar testing in Entity Framework 4, but now I cant find it. So, how do I test my EF4 Code-Only mappings?

• asp.net mvc 2 multithread

  - by Chris Cap

  I'm getting some weird behavior in asp.net MVC2 (at least it's not what I'm expecting). I have a controller httppost action that processes credit cards. I'm setting a session variable on the server to let me know if a user has attempted to process a card. I clear that session variable when I'm done. I am doing some very quick posts to test the process and the session variable is coming back null everytime because I clear the session variable at the end of the process. I have some debug prints that show me that the all requests are processed synchronously. That is...the first attempt occurs, it fails, session variable is cleared, second attempt tries and fails and the variable is cleared, etc... My first thought was that this was a side effect of debugging and that it just lined requests up for debugging purposes using the local webserver. So I put it on a development server and the same thing is occurring. Multiple submits/posts are processed synchronously. I even put a System.Threading.Sleep in there to make sure it would stop right after I set the session variable and it still won't even START the second request until the first is done. Has anyone else seen this behavior? My understanding was that a worker process was spawned for each request and that these actions could happen asychronously. Here's some psuedo code if (Session["CardCharged"] != null) return RedirectToAction("Index", "Problem"); Session["CardCharged"] = false; //starting the process System.Threading.Thread.Sleep(10000); //charge card here if (!providerResponse.IsApproved) { System.Diagnostics.Debug.WriteLine("failed"); Session["CardCharged"] = null; //have to allow them to charge again since this failed return View(myModel); } Session["CardCharged"] = true; return RedirectToAction("Index", "OrderComplete"); I should mention that my code ALWAYS fails the credit card check for testing purposes. I'm trying to test the situation where processing is STILL occurring and redirect the user elsewhere. I have set a dummy session variable elsewhere to assure that the session id "sticks". So I know the session id is the same for each request. Thanks

• Accessing Custom Configurations in NUnit class

  - by Martin Ongtangco

  I'm really banging my head onto this one. I can't make the Custom Configuration to work with NUnit. It kept on failing to read the configuration file. I followed carefully this article: http://devlicio.us/blogs/derik_whittaker/archive/2006/11/13/app-config-and-custom-configuration-sections.aspx placed the references in the Unit test class App.Config, still everything failed. Is there some sort of a magic setting to do here?

• When an active_record is saved, is it saved before or after its associated object(s)?

  - by SeeBees

  In rails, when saving an active_record object, its associated objects will be saved as well. But has_one and has_many association have different order in saving objects. I have three simplified models: class Team < ActiveRecord::Base has_many :players has_one :coach end class Player < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end class Coach < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end I use the following code to test these models: t = Team.new team.coach = Coach.new team.save! team.save! returns true. But in another test: t = Team.new team.players << Player.new team.save! team.save! gives the following error: > ActiveRecord::RecordInvalid: > Validation failed: Players is invalid I figured out that when team.save! is called, it first calls player.save!. player needs to validate the presence of the id of the associated team. But at the time player.save! is called, team hasn't been saved yet, and therefore, team_id doesn't yet exist for player. This fails the player's validation, so the error occurs. But on the other hand, team is saved before coach.save!, otherwise the first example will get the same error as the second one. So I've concluded that when a has_many bs, a.save! will save bs prior to a. When a has_one b, a.save! will save a prior to b. If I am right, why is this the case? It doesn't seem logical to me. Why do has_one and has_many association have different order in saving? Any ideas? And is there any way I can change the order? Say I want to have the same saving order for both has_one and has_many. Thanks.
