  • NHibernate + Cannot insert the value NULL into...

    - by mybrokengnome
    I've got a MS-SQL database with a table created with this code CREATE TABLE [dbo].[portfoliomanager]( [idPortfolioManager] [int] NOT NULL PRIMARY KEY IDENTITY, [name] [varchar](45) NULL ) so that idPortfolioManager is my primary key and also auto-incrementing. Now on my Windows WPF application I'm using NHibernate to help with adding/updating/removing/etc. data from the database. Here is the class that should be connecting to the portfoliomanager table namespace PortfolioManager { [Class(Table="portfoliomanager",NameType=typeof(PortfolioManagerClass))] public class PortfolioManagerClass { [Id(Name = "idPortfolioManager")] [Generator(1, Class = "identity")] public virtual int idPortfolioManager { get; set; } [NHibernate.Mapping.Attributes.Property(Name = "name")] public virtual string name { get; set; } public PortfolioManagerClass() { } } } and some short code to try and insert something PortfolioManagerClass portfolio = new PortfolioManagerClass(); Portfolio.name = "Brad's Portfolios"; The problem is, when I try running this, I get this error: {System.Data.SqlClient.SqlException: Cannot insert the value NULL into column 'idPortfolioManager', table 'PortfolioManagementSystem.dbo.portfoliomanager'; column does not allow nulls. INSERT fails. The statement has been terminated... with an outer exception of {"could not insert: [PortfolioManager.PortfolioManagerClass][SQL: INSERT INTO portfoliomanager (name) VALUES (?); select SCOPE_IDENTITY()]"} I'm hoping this is the last error I'll have to solve with NHibernate just to get it to do something, it's been a long process. Just as a note, I've also tried setting Class="native" and unsaved-value="0" with the same error. Thanks! Edit: Ok removing the 1, from Generator actually allows the program to run (not sure why that was even in the samples I was looking at) but it actually doesn't get added to the database. I logged in to the server and ran the sql server profiler tool and I never see the connection coming through or the SQL its trying to run, but NHibernate isn't throwing an error anymore. Starting to think it would be easier to just write SQL statements myself :(

  • Get nul value from one ViewController to one ViewController

    - by sovannarith
    I have 2 ViewControllers namely V1 and V2. I want to pass value from V2 to V1 but I get value 0 for countV1 in V1. I saw more questions in stackoverflow but I can't deal with this small problem. I use ARC. In V1 .h file @property(nonatomic,unsafe_unretained) int countV1; .m file @synthesize countV1; In V2 .m file int countV2 = 1; V1 *v1 = [V1 alloc] initWithNibName:@"V1" bundle:nil]; v1.countV1 = countV2;

  • Binding a value to one of two possibilities in Guice

    - by Kelvin Chung
    Suppose I have a value for which I have a default, which can be overridden if System.getProperty("foo") is set. I have one module for which I have bindConstant().annotatedWith(Names.named("Default foo")).to(defaultValue); I'm wondering what the best way of implementing a module for which I want to bind something annotated with "foo" to System.getProperty("foo"), or, if it does not exist, the "Default foo" binding. I've thought of a simple module like so: public class SimpleIfBlockModule extends AbstractModule { @Override public void configure() { requireBinding(Key.get(String.class, Names.named("Default foo"))); if (System.getProperties().containsKey("foo")) { bindConstant().annotatedWith(Names.named("foo")).to(System.getProperty("foo")); } else { bind(String.class).annotatedWith(Names.named("foo")).to(Key.get(String.class, Names.named("Default foo"))); } } } I've also considered creating a "system property module" like so: public class SystemPropertyModule extends PrivateModule { @Override public void configure() { Names.bindProperties(binder(), System.getProperties()); if (System.getProperties().contains("foo")) { expose(String.class).annotatedWith(Names.named("foo")); } } } And using SystemPropertyModule to create an injector that a third module, which does the binding of "foo". Both of these seem to have their downsides, so I'm wondering if there is anything I should be doing differently. I was hoping for something that's both injector-free and reasonably generalizable to multiple "foo" attributes. Any ideas?

  • How do I get the default constructor value in a function

  • how to hook key event.

    - by backspace7
    I'd like to limit the text length of EditText widget, And if user type more charactes than the limited length, I want to show a kind of warning popup, however I can't show popup. The problem is that we can't show popup while typing, Probably, many people think a way of utilizing OnKeyListener or OnKeyDown. But, when the word is composing, nothing come into OnKeyListener or OnKeyDown, So, we can't show popup when we want to. Is there anyone who have smart idea to solve this problem?

  • What exactly is a "key container"?

    - by saugata
    Is it something specific, with a definite structure, or just an arbitrary data file with some form of encryption to hold keys, and potentially other secret information? Can someone please explain the term or point me to a link.

  • What are the hibernate annotations used to persist a Map with an enumerated type as a key?

    - by Jason Novak
    I am having trouble getting the right hibernate annotations to use on a Map with an enumerated class as a key. Here is a simplified (and extremely contrived) example. public class Thing { public String id; public Letter startLetter; public Map<Letter,Double> letterCounts = new HashMap<Letter, Double>(); } public enum Letter { A, B, C, D } Here are my current annotations on Thing @Entity public class Thing { @Id public String id; @Enumerated(EnumType.STRING) public Letter startLetter; @CollectionOfElements @JoinTable(name = "Thing_letterFrequencies", joinColumns = @JoinColumn(name = "thingId")) @MapKey(columns = @Column(name = "letter", nullable = false)) @Column(name = "count") public Map<Letter,Double> letterCounts = new HashMap<Letter, Double>(); } Hibernate generates the following DDL to create the tables for my MySql database create table Thing (id varchar(255) not null, startLetter varchar(255), primary key (id)) type=InnoDB; create table Thing_letterFrequencies (thingId varchar(255) not null, count double precision, letter tinyblob not null, primary key (thingId, letter)) type=InnoDB; Notice that hibernate tries to define letter (my map key) as a tinyblob, however it defines startLetter as a varchar(255) even though both are of the enumerated type Letter. When I try to create the tables I see the following error BLOB/TEXT column 'letter' used in key specification without a key length I googled this error and it appears that MySql has issues when you try to make a tinyblob column part of a primary key, which is what hibernate needs to do with the Thing_letterFrequencies table. So I would rather have letter mapped to a varchar(255) the way startLetter is. Unfortunately, I've been fussing with the MapKey annotation for a while now and haven't been able to make this work. I've also tried @MapKeyManyToMany(targetEntity=Product.class) without success. Can anyone tell me what are the correct annotations for my letterCounts map so that hibernate will treat the letterCounts map key the same way it does startLetter?

  • checkbox selected value is lost after coming back to the pagei.e., viewstate value is lost with use

    - by M.Vijay bhasker
    In the left navigation i have a series of check boxes and a grid view in the page body.Grid view results changes based on the check box selection,whenever i click on the links in grid view it goes to the second page and there is a link on the page which takes me back to the first page,but the check box selected value is maintained for the first time only and if we repeat the same process for the second time and i see that the first time selection of the check box is maintained.Here the grid view is placed in update panel and the check box in the left is called using .... AsyncPostBackTrigger ControlID="cphLeftNavigation". I've tried removing the above code referring the cphLeftNavigation and i see the results are coming up correctly and the last selected check box value is being maintained correctly and i want the same functionality to be implemented with/without update panel. Can anyone let me know,what exactly should i change to implement the above mentioned functionality.

  • Value from UISlider method?

  • How to sort time column by value instead of alphabetically

    - by Turch
    I'm creating a pivot table by connecting to an SSAS tabular model (Data - From Other Sources - From Analysis Services) . The model has a "time" column that I want to sort by. The default (database) sorting is earliest to latest: When I click the triangle next to 'Row Labels' and select "Sort A to Z", I get alphabetically sorted times: How can I get the times to sort by time? Changing the number format from "General" to "Time" does nothing. The times aren't stored as text either - the data type of the column in the SSAS model is Auto (Date)

  • Show image in cell based on cell value

    - by JoeM
    I am creating a weekly income comparison table. I want to compare A5 and A10 cells and display appropriate image in B7 cell. The image will be either UP or DOWN arrow (which reflects increase or decrease). I've created a formula which puts text up or down in the cell, but I don't know how to replace it with the up/down image. =IF(D77>D69, "up", IF(D77<D69, "down")) How can I do it? I know it's possible. Note: I am using Google Docs Excel, so please let me know if this cannot be done in it, but I have to use the real Excel installed on my laptop.

  • function to efficiently check a change of value in a nested hashmap

    - by zcaudate
    the motivation is for checking what has changed in a deeply nest map, kind of like a reverse of update-in. This is a simple example: (def p1 {:a {:a1 :1 :a2 :2} :b {:b1 :1 :b2 :2}}) (def p2 (update-in p1 [:a :a1] (constantly :updated)) ;; => {:a {:a1 :updated :a2 :2} ;; :b {:b1 :1 :b2 :2}} (what-changed? p1 p2) ;; => {:keys [:a :a1] :value :updated) (what-changed? p2 p1) ;; => {:keys [:a :a1] :value :2) I'm hoping that because clojure maps are persistent data-structures, there may be a smart algorithm to figure this out by looking at the underlying structure as opposed to walking through the nested maps and comparing the difference.

  • (Python) algorithm to randomly select a key based on proportionality/weight

    - by LaundroMat
    Hi - I'm a bit at a loss as to how to find a clean algorithm for doing the following: Suppose I have a dict k: >>> k = {'A': 68, 'B': 62, 'C': 47, 'D': 16, 'E': 81} I now want to randomly select one of these keys, based on the 'weight' they have in the total (i.e. sum) amount of keys. >>> sum(k.values()) >>> 274 So that there's a >>> 68.0/274.0 >>> 0.24817518248175183 24.81% percent change that A is selected. How would you write an algorithm that takes care of this? In other words, that makes sure that on 10.000 random picks, A will be selected 2.481 times?

  • GPG - why am I encrypting with subkey instead of primary key?

    - by khedron
    When encrypting a file to send to a collaborator, I see this message: gpg: using subkey XXXX instead of primary key YYYY Why would that be? I've noticed that when they send me an encrypted file, it also appears to be encrypted towards my subkey instead of my primary key. For me, this doesn't appear to be a problem; gpg (1.4.x, macosx) just handles it & moves on. But for them, with their automated tool setup, this seems to be an issue, and they've requested that I be sure to use their primary key. I've tried to do some reading, and I have the Michael Lucas's "GPG & PGP" book on order, but I'm not seeing why there's this distinction. I have read that the key used for signing and the key used for encryption would be different, but I assumed that was about public vs private keys at first. In case it was a trust/validation issue, I went through the process of comparing fingerprints and verifying, yes, I trust this key. While I was doing that, I noticed the primary & subkeys had different "usage" notes: primary: usage: SCA subkey: usage: E "E" seems likely to mean "Encryption". But, I haven't been able to find any documentation on this. Moreover, my collaborator has been using these tools & techniques for some years now, so why would this only be a problem for me?

  • Windows Macro + Hot Key - Paste Without Formatting

    - by JasonStoltz
    Not sure if this appropriate to put as a question or not? It's sort of a scripting question I think. Just down vote me if not :p Basically, what I'm looking for is a way to push a windows hotkey and have whatever text is in the clipboard be stripped of formatting. An example of what the macro could do: I push (whatever hotkey combo here) open notepad.exe Paste to notepad from clipboard Select all text in notepad Copy/Cut all text from notepad Close notepad I'm just wondering if someone has done something like this before, or knows how it could be accomplished. I think this could be a huge time-saver for almost anyone. I find myself doing this all the time when cutting and pasting between different office applications, etc.

  • C++ Boost bind value type

    - by aaa
    hello. I look in documentation and source code but cannot figure out how to get return value type of boost bind functor. I am trying to accomplish following: 35 template<typename T,size_t N, class F> 36 boost::array<typename F::value_type, N> make_array(T (&input)[N], F unary) { 37 boost::array<typename F::value_type, N> array; 38 std::transform(input, input + N, array.begin(), unary); 39 return array; 40 } where F can be bind functor. the above does not work because functor does not have value_type. for that matter, is there standard interface for unary/binary functor as far as return value. Thanks

  • Looking up a value, depending on which set of dates another date falls between

    - by Ruffles
    Hello, and apologies if this is a duplicate - if you could point me in the direction of any existing answers, that would be great. I have a set of date ranges in Excel, each of which has some kind of label. e.g. LabelA 01/01/10 31/01/10 LabelB 01/02/10 28/02/10 LabelC 01/03/10 31/03/10 If I have another date, I would like to look up the label relating to the date range within which this date falls. e.g. For 15/02/10 I would like to return LabelB. I know that the date ranges will not overlap, although there could be a gap between the end date of one, and the start date of the next.

  • Convert PHP array into Key => Value Array

    - by Feature
    Total PHP Noob and I couldn't find an answer to this specific problem. Hope someone can help! $myvar is an array that looks like this: Array ( [aid] = Array ( [0] = 2 [1] = 1 ) [oid] = Array( [0] = 2 [1] = 1 ) ) And I need to set a new variable (called $attributes) to something that looks like this: $attributes = array($myvar['aid'][0] => $myvar['oid'][0], $myvar['aid'][1] => $myvar['oid'][1], etc...); And, of course, $myvar may contain many more items... How do I iterate through $myvar and build the $attributes variable?
