  • Auto mapping a IDictionary<string, myclass> with fluent nhibernate

    - by Marcus
    I have a simple class that looks like this: public class Item { // some properties public virtual IDictionary<string, Detail> Details { get; private set; } } and then I have a map that looks like this: map.HasMany(x => x.Details).AsMap<string>("Name").AsIndexedCollection<string>("Name", c => c.GetIndexMapping()).Cascade.All().KeyColumn("Item_Id")) with this map I get the following error and I don't know how to solve it? The type or method has 2 generic parameter(s), but 1 generic argument(s) were provided. A generic argument must be provided for each generic parameter.

  • Using Linq2Sql to insert data into multiple tables using an auto incremented primary key

    - by Thomas
    I have a Customer table with a Primary key (int auto increment) and an Address table with a foreign key to the Customer table. I am trying to insert both rows into the database in one nice transaction. using (DatabaseDataContext db = new DatabaseDataContext()) { Customer newCustomer = new Customer() { Email = customer.Email }; Address b = new Address() { CustomerID = newCustomer.CustomerID, Address1 = billingAddress.Address1 }; db.Customers.InsertOnSubmit(newCustomer); db.Addresses.InsertOnSubmit(b); db.SubmitChanges(); } When I run this I was hoping that the Customer and Address table automatically had the correct keys in the database since the context knows this is an auto incremented key and will do two inserts with the right key in both tables. The only way I can get this to work would be to do SubmitChanges() on the Customer object first then create the address and do SubmitChanges() on that as well. This would create two roundtrips to the database and I would like to see if I can do this in one transaction. Is it possible? Thanks

  • UTF-8 to ISO-8859-1 mapping / lossless conversion libraries in Java

    - by Pawel Krupinski
    I need to perform a conversion of characters from UTF-8 to ISO-8859-1 in Java without losing for example all of the UTF-8 specific punctuation. Ideally would like these to be converted to equivalents in ISO (e.g. there are probably 5 different single quotes in UTF-8 and would like them all converted to ISO single quote character). String.getBytes("ISO-8859-1") just won't do the trick in this case as it will lose the UTF-8-specific chars. Do you know of any ready mappings or libraries in Java that would map UTF-8 specific characters to ISO?

  • NHibernate Collection Mapping - Read Only Properties

    - by Chris Meek
    I have the following class public class Person { private IList<Person> _children; public IEnumerable<Person> Children { get; } public void AddChild(Person child) { // Some business logic and adding to the internal list } } What changes would I have to make for NHibenrate to be able to persist the Child collection (apart from making everything virtual, I know that one). Do I have to add a setter to the children property which does something like a _children.Clear(); _children.AddRange(value). Currently the model expresses my intent quite nicely but I'm not sure how much alteration is need for NH to be able to help me out with persistence.

  • Doctrine Default Primary Key Problem (Again)

    - by 01010011
    Hi, Should I change all of my uniquely-named MySQL database primary keys to 'id' to avoid getting errors related to Doctrine's default primary key set in the plugin 'doctrine_pi.php'? To further elaborate, I am getting the following reoccurring error, this time after trying to login to my login page: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'u.book_id' in 'field list'' in... I suspect the problem resides at a MySQL table used for my login, of which has a primary key called id Marc B originally solved an identical problem for me in this post http://stackoverflow.com/questions/2702229/doctrine-codeigniter-mysql-crud-errors when I had the same problem with a different table within the same database. Following his suggestion, I changed the default primary key located at system/application/plugins/doctrine_pi.php from 'id' to 'book_id': <?php // system/application/plugins/doctrine_pi.php ... // set the default primary key to be named 'id', integer, 4 bytes Doctrine_Manager::getInstance()->setAttribute( Doctrine::ATTR_DEFAULT_IDENTIFIER_OPTIONS, array('name' => 'book_id', 'type' => 'integer', 'length' => 4)); and that solved my previous problem. However, my login page stopped working. So what is the safe thing to do? Change all of my primary keys to 'id' (will that solve the problem without causing some other problem I am not aware of). Or should I add some lines of code in doctrine_pi.php?

  • Mapping Hilbert values to 3D points

    - by Alexander Gladysh
    I have a set of Hilbert values (length from the start of the Hilbert curve to the given point). What is the best way to convert these values to 3D points? Original Hilbert curve was not in 3D, so I guess I have to pick by myself the Hilbert curve rank I need. I do have total curve length though (that is, the maximum value in the set). Perhaps there is an existing implementation? Some library that would allow me to work with Hilbert curve / values? Language does not matter much.

  • Mapping of relative path to absolute path of webpage links

    - by Sagar
    I am Final Year IT Engineering student. I am Doing Content Management System in ASP.net for my college. I have given link on my master page for various pages in the application; where I have specified only relative path of those pages. When I run this project and follow any link it works well for only first time and for second time when I click any link it .net run time environment unable to find the absolute address of that page. This may be problem due to relative addressing. How can I resolve this problem? Can anybody help me out?

  • Compute the AES-encryption key given the plaintext and its ciphertext?

    - by Null Pointers etc.
    I'm tasked with creating database tables in Oracle which contain encrypted strings (i.e., the columns are RAW). The strings are encrypted by the application (using AES, 128-bit key) and stored in Oracle, then later retrieved from Oracle and decrypted (i.e., Oracle itself never sees the unencrypted strings). I've come across this one column that will be one of two strings. I'm worried that someone will notice and presumably figure out what those two values to figure out the AES key. For example, if someone sees that the column is either Ciphertext #1 or #2: Ciphertext #1: BF,4F,8B,FE, 60,D8,33,56, 1B,F2,35,72, 49,20,DE,C6. Ciphertext #2: BC,E8,54,BD, F4,B3,36,3B, DD,70,76,45, 29,28,50,07. and knows the corresponding Plaintexts: Plaintext #1 ("Detroit"): 44,00,65,00, 74,00,72,00, 6F,00,69,00, 74,00,00,00. Plaintext #2 ("Chicago"): 43,00,68,00, 69,00,63,00, 61,00,67,00, 6F,00,00,00. can he deduce that the encryption key is "Buffalo"? 42,00,75,00, 66,00,66,00, 61,00,6C,00, 6F,00,00,00. I'm thinking that there should be only one 128-bit key that could convert Plaintext #1 to Ciphertext #1. Does this mean I should go to a 192-bit or 256-bit key instead, or find some other solution? (As an aside, here are two other ciphertexts for the same plaintexts but with a different key.) Ciphertext #1 A ("Detroit"): E4,28,29,E3, 6E,C2,64,FA, A1,F4,F4,96, FC,18,4A,C5. Ciphertext #2 A ("Chicago"): EA,87,30,F0, AC,44,5D,ED, FD,EB,A8,79, 83,59,53,B7.

  • Why OpenGL ES texture mapping is very slow?

    - by Cinar
    I have an Android application that displays VGA (640x480) frames using OpenGL ES. The application reads each frame from a movie file and updates the texture accordingly. My problem is that, it is taking almost 30 ms. to draw each frame using OpenGL. Similar test using the Canvas/drawBitmap was around 6 ms on the same device. I'm following the same OpenGL calls that VLC Media Player is using, so I'm assuming that those are optimized for this purpose. I just wanted to hear your thoughts and ideas about it?

  • [Java] Implement a RSA algorithm

    - by Robin Monjo
    Hello everyone. I want to implement a RSA algorithm to encrypt an image (byte[]). To generate my two keys I used this piece of code : KeyPairGenerator keygen = KeyPairGenerator.getInstance("RSA"); keygen.initialize(512); keyPair = keygen.generateKeyPair(); Once public and private key are generated, I would like to show them to the user so he can distribute the public key and use the private key to decode. How can I get back those key ? Using keygen.getPrivateKey() and keygen.getPublicKey() give me all the information of the RSA algorithm, not only the keys I need. Thanks

  • Need help in understanding the mapping of user-space send, sendto, sendmsg to kernel-space sendmsg

    - by bala1486
    Hello, I am trying to implement my own transport layer protocol in Linux for an experiment. I am going to use socket interface and add my protocol using sock_register. For the proto_ops i can see that the parameters for the sendmsg and recvmsg are (struct kiocb *iocb, struct socket *sock, struct msghdr *msg, size_t len, int flags). But there are three types of user api's send, sendto, sendmsg. Of these three only sendmsg contains a parameter for msghdr. I find that the other two api's are incompatible with the parameters supplied by the kernel to my kernel-space sendmsg function. So what happens when we use send and sendto user-space api's? Hope i am clear.. Thanks, Bala

  • SQL multiple primary keys - localization

    - by Max Malmgren
    I am trying to implement some localization in my database. It looks something like this (prefixes only for clarification) tbl-Categories ID Language Name tbl-Articles ID CategoryID Now, in my tbl-Categories, I want to have primary keys spanning ID and language, so that every combination of ID and language is unique. In tbl-Articles I would like a foreign key to reference ID in categories, but not Language, since I do not want to bind an article to a certain language, only category. Of course, I cannot add a foreign key to part of the primary key. I also cannot have the primary key only on the ID of categories, since then there can only be one language. Having no primary keys disables foreign keys altogether, and that is also not a great solution. Do you have any ideas how I can solve this in an elegant fashion? Thanks.

  • C# KeyEvent doesn't log the enter/return key

    - by Pieter888
    Hey all, I've been making this login form in C# and I wanted to 'submit' all the data as soon as the user either clicks on submit or presses the enter/return key. I've been testing a bit with KeyEvents but nothing so far worked. void tbPassword_KeyPress(object sender, KeyPressEventArgs e) { MessageBox.Show(e.KeyChar.ToString()); } The above code was to test if the event even worked in the first place. It works perfectly, when I press 'd' it shows me 'd' when I press '8' it shows me '8' but pressing enter doesn't do anything. So I though this was because enter isn't really bound to a character but it did show backspace, it worked just fine so it got me confused about why it didn't register my enter key. So the question is: How do I log the enter/return key? and why doesn't it log the key press right right now like it should? note: I've put the event in a textbox tbPassword.KeyPress += new KeyPressEventHandler(tbPassword_KeyPress); So it fires when the enter button is pressed WHILE the textbox is selected (which is was the whole time of course) maybe that has something to do with the execution of the code.

  • Mapping java.util.Date to xs:date instead of xs:dateTime in JAX-WS

    - by Larsing
    Hi all, We hav an EJB, jws-anotated as a web service. It has a pretty complex pojo-model that generates an equally complex xsd. The pojos contain numerous java.util.Date. These all map to xs:dateTime. This service is used as "business service" in Oracle(BEA) OSB(AquaLogic). We also have a "proxy service" which we map to the BS with XQuery (the OSB/AquaLogic way). The proxy service's xsd has xs:date for the corresponding fields. For some reason, Oracle's implementation of XQuery does not support casting from xs:date to xs:dateTime(!). I could solve this by casting to xs:string and concat:ing with "T00:00:00", however, i would rather try to get JAX-WS to generate an xsd with xs:date instead. Only, I can't find any info on how to do this (anotations?). Can anyone give me a hint? Kind regards, Lars

  • case insensitive mapping for Spring MVC @RequestMapping annotations

    - by Zahid Riaz
    I have Controller having multiple @RequestMapping annotations in it. @Controller public class SignUpController { @RequestMapping("signup") public String showSignUp() throws Exception { return "somejsp"; } @RequestMapping("fullSignup") public String showFullSignUp() throws Exception { return "anotherjsp"; } @RequestMapping("signup/createAccount") public String createAccount() throws Exception { return "anyjsp"; } } How can I map these @RequestMapping to case insensitive. i.e. if I use "/fullsignup" or "/fullSignup" I should get "anotherjsp". But this is not happening right now. Only "/fullSignup" is working fine.

  • Mapping a drop-down menu over an image

    - by Pieter
    I have a menu bar that is rotated slightly. Here are two buttons as an example: As a result, I can't use regular HTML to handle this. I need to use a <map> to put hyperlinks over the menu parts. (Or am I missing a killer CSS feature I don't know about?) I want to map drop-down menus to these buttons. This looks like a nice way to implement drop-down menus: http://javascript-array.com/scripts/simple_drop_down_menu/ However, this does not work on <map>s, I believe. Or am I wrong? Is there a different approach I can take to constructing drop-down menus for a menu bar that is not aligned horizontally?

  • Mapping an Array to a Single Row

    - by João Bragança
    I have the following classes: public class InventoryItem { private Usage[] usages = new Usage[12]; virtual public Usage[] Usages { get { return usages; }} virtual public string Name{get;set;} } public class Usage { virtual public double Quantity{get;set;} virtual public string SomethingElse{get;set;} } I know that Usages.Length will always be 12. I think it would be best to store it in the DB like so: Name nvarchar(64), Usage_Quantity_0 float, Usage_SomethingElse_0 nvarchar(16), Usage_Quantity_1 float, Usage_SomethingElse_1 nvarchar(16), ... Usage_Quantity_11 float, Usage_SomethingElse_11 nvarchar(16), How can I get this done?

  • Mapping child objects in fluent nhibernate to a read-only view

    - by grenade
    Given that I am implementing a read-only UI, how do I create a ClassMap for Shop: public class Shop { public int Id { get; set; } public City City { get; set; } } public class City { public string Name { get; set; } public string CountryCode { get; set; } } The DB interface for Shops is a View containing 3 columns (ShopId, CityName, CountryCode). I was hoping to do something like this: public sealed class ShopMap : ClassMap<Shop> { public ShopMap() { Table("Shop"); Id(x => x.Id, "ShopId"); Map(x => x.City.Name, "CityName"); Map(x => x.City.CountryCode, "CountryCode"); } } Will fluent auto-instantiate Shop.City?

  • Mapping US zip code to time zone

    - by Doug Kavendek
    When users register with our app, we are able to infer their zip code when we validate them against a national database. What would be the best way to determine a good potential guess of their time zone from this zip code? We are trying to minimize the amount of data we explicitly have to ask them for. They will be able to manually set the time zone later if our best guess is wrong. I realize zip codes won't help with figuring out the time zone outside the US, but in that case we'd have to manually ask anyway, and we deal predominantly with the US regardless. I've found a lot of zip code databases, and so far only a few contain time zone information, but those that do are not free, such as this one. If it's absolutely necessary to pay a subscription to a service in order to do this, then it will not be worth it and we will just have to ask users explicitly. Although language isn't particularly relevant as I can probably convert things however needed, we're using PHP and MySQL.
