  • Why can't I inject value null with Ninjects ConstructorArgument?

    - by stiank81
    When using Ninjects ConstructorArgument you can specify the exact value to inject to specific parameters. Why can't this value be null, or how can I make it work? Maybe it's not something you'd like to do, but I want to use it in my unit tests.. Example: public class Ninja { private readonly IWeapon _weapon; public Ninja(IWeapon weapon) { _weapon = weapon; } } public void SomeFunction() { var kernel = new StandardKernel(); var ninja = kernel.Get<Ninja>(new ConstructorArgument("weapon", null)); }

  • What will be the value of i in the following pseudocode?

    - by user283403
    I got this question in a programming test. Do you think this question is even correct? Look at the answer choices. (2^x means 2 raised to x) Consider the following pseudocode. x := 1; i := 1; while (x = 1000) begin x := 2^x; i := i + 1; end; What is the value of i at the end of the pseudocode? a) 4 b) 5 c) 6 d) 7 e) 8 I am sure that the value of i will 1. I told the examiner of the discrepancy and he advised me the leave the question unanswered if I felt it was incorrect. What else could I have done?

  • How to pass a variable to an awk print parameter...

    - by Jamie
    I'm trying extract the nth + 1 and nth + 3 columns from a file. This is what tried, which is a useful pseudo code: for i in {1..100} ; do awk -F "," " { printf \"%3d, %12.3f, %12.3f\\n\", \$1, \$($i+1), \$($i+3) } " All_Runs.csv > Run-$i.csv which, obviously doesn't work (but it seemed reasonable to hope). How can I do this?

  • Cannot use String.Empty as a default value for an optional parameter in C# - then what's the point?

    - by Mikeyg36
    I am reading Effective C# by Bill Wagner. In Item 14 - Minimize Duplicate Initialization Logic, he shows the following example of using the new optional parameters feature in a constructor: public MyClass(int initialCount = 0, string name = "") Notice that he used "" instead of string.Empty. He comments: You'll note [in an example above] that the second constructor specified "" for the default value on the name parameter, rather than the more customary string.Empty. That's because string.Empty is not a compile-time constant. It is a static property defined in the string class. Because it is not a compile constant, you cannot use it for the default value for a parameter. If we cannot use the string.Empty static in all situations, then doesn't that defeat the purpose of it? I thought that we would use it to be sure that we have a system-independent means of referring to the empty string. Is my understanding wrong? Thanks.

  • How do I pass a multi-dimensional array as a GET parameter in PHP?

    - by Onema
    I have the following code. $connect = new Connection (); $response = $connect->putFile($fileName, $destination); header("Location: /test.php?response=" . $response); When I invoke header with the response, the file will stop execution, but I will have no error in the console... I am thinking maybe this array needs to be encoded for the url? if that is the case how? Thank you

  • How to get JSON objects value if it's name contains dots?

    - by manakor
    I have a very simple JSON array (please focus on "points.bean.pointsBase" object): var mydata = {"list": [ {"points.bean.pointsBase": [ {"time": 2000, "caption":"caption text", duration: 5000}, {"time": 6000, "caption":"caption text", duration: 3000} ] } ] }; // Usually we make smth like this to get the value: var smth = mydata.list[0].points.bean.pointsBase[0].time; alert(smth); // should display 2000 But, unfortunately, it does display nothing. When I change "points.bean.pointsBase" to smth without dots in it's name - everything works! However, I can't change this name to anything else without dots, but I need to get a value?! Is there any options to get it?

  • How to disable a warning in Delphi about "return value ... might be undefined"?

    - by Lasse V. Karlsen
    I have a function that gives me the following warning: [DCC Warning] filename.pas(6939): W1035 Return value of function 'function' might be undefined The function, however, is clean, small, and does have a known, expected, return value. The first statement in the function is: Result := ''; and there is no local variable or parameter called Result either. Is there any kind of pragma-like directive I can surround this method with to remove this warning? This is Delphi 2007. Unfortunately, the help system on this Delphi installation is shot, so I can't pop up the help for that warning right now. Anyone know off the top of their head what I can do?

  • Is it possible to set a parameterized build or pass an environment variable via a hudson build trigger?

    - by Tim
    I'd like to use hudson to trigger a "promotion" of a build. The build would be a simple script that just copies a release candidate installer file from one location to another. (development dir to release/stable dir) Our build server is not on the public internet, but I want to be able to send an email or a text message or an IM with the build number to hudson, which will parse the build number and then do the copy/move. In looking at the jabber/IM plugin it does not look like this is possible (the parameter part) Has anyone solved this in some way? Should I use some other mechanism? I would prefer not to have to do the manual steps each time (SCP/FTP, etc) - I just want any QA team member to be able to trigger the build server to do the promotion.

  • Pass information to php file from javascript while restricting user from doing it their self?

    - by Sean Madigan
    I am making a game where the battle system uses javascript to battle. At the end of the battle you either win or lose. If the user wins, I need to update the mysql database with the XP they earned. The best way I can think of doing this is to have the javascript run an ajax function when the user wins that POSTs something like addxp.php?amount=235, but if I do that then the user can easilly look at the source and see that they can just enter in that page themself to update their xp without battling. But this is the only way I know how to do it? Help please :-/

  • How to assign a value to an pointer-pointer passed in call by reference?

    - by mystify
    I want to achieve something similar to what these guys do here: - (NSUInteger)countForFetchRequest:(NSFetchRequest *)request error:(NSError **)error like you can see, you pass an NSError pointer and that nice method will assign a real NSError object to your pointer in case there is an error. So the cool thing about this is, that the method returns an NSUInteger but can ALSO return an NSError, without having to mess around with ugly and fat arrays or dictionaries. So how could I assign an object to the passed-in error pointer?

  • How do I display the current value of an Android Preference in the Preference summary?

    - by nyenyec
    This must come up very often. When the user is editing preferences in an Android app, I'd like them to be able to see the currently set value of the preference in the Preference summary. Example: if I have a Preference setting for "Discard old messages" that specifies the number of days after which messages need to be cleaned up. In the PreferenceActivity I'd like the user to see: "Discard old messages" <- title "Clean up messages after x days" <- summary where x is the current Preference value Extra credit: make this reusable, so I can easily apply it to all my preferences regardless of their type (so that it work with EditTextPreference, ListPreference etc. with minimal amount of coding).
