    - by Akk
    How can i create a 3 table schema from the following model classes. public class Product { public int Id {get; set;} public string Name {get; set;} public IList<Photo> Photos {get; set;} } public class Photo { public int Id {get; set;} public string Path {get; set;} } I want to create the following table structure in the database: Product ------- Id Name ProductPhotos ------------- ProductId (FK Products.Id) PhotoId (FK Photos.Id) Photos ------ Id Path How i can express the above Database Schema using Fluent NHibernate? I could only manage the following the Mapping but this does not get me the 3rd Photo ref table. public class ProductMap : ClassMap<Product> { public CityMap() { Id(x => x.Id); Map(x => x.Name); Table("Products"); HasMany(x => x.Photos).Table("ProductPhotos").KeyColumn("ProductId"); } }

    - by TerrorAustralis
    Hi guys, I have a class, for experiment sake call it foo() and another class, call it bar() I have a data template for class foo() defined in my xaml, but one of foo()'s properties is a bar() object such that foo() { Public string Name {get; set;} Public int ID {get; set;} Public bar barProp {get; set;} } and bar() { Public string Description{get; set;} } I want my data template of foo to display the Description property of bar. I have tried the simple <textblock Text="{Binding Path=barProp.Description}" /> and variants to no avail Seeking wisdom, DJ

  • Trouble creating a makefile

    - by catia
    Hi everyone! I'm having some trouble making a Makefile. Write now I just compile everything every time. Although, the professor is ok with that, I do want to get it working faster and to avoid unnecessary compiling. Here's what I have. FILES= p6.cpp SetIter.cpp Node.cpp Set.cpp CFLAGS= -ansi -pendantic -Wall -Wextra CC= g++ MakePg6: p6.cpp SetIter.cpp Node.cpp Set.cpp $(CC) $(CFLAGS) $(FILES) -o pg6 Node.cpp - node class Set.cpp - uses nodes. Friend of Node. SetIter.cpp - gets a set and uses a pointer to iterator through I'm confused with some of the depencies arising from the friends thing and the point of lib.o being included in the Makefile as some sites have. Any help is greatly appreciated. Thanks in advance.

  • Using database default values with Linq to SQL codewise

    - by Ivo
    I am using Dynamic Data with linq to SQL and SQL Server 2008. I have a GUID column that gets his value from the default value with newguid(). When I set IsDbGenerated to true in the designer it works like a charm. But when I renew table this property is set back to false again. So I added it to the metadata. For some reason it's not being pickup, "00000000-0000-0000-0000-000000000000" is being inserted in database. The displayname and readonly change are being pick up. What am I missing? [MetadataType(typeof(CMS_Data_HistoryMetadata))] public partial class CMS_Data_History { } [TableName("Content")] public class CMS_Data_HistoryMetadata { [DisplayName("Pagina Title")] public object pageTitleBar { get; set; } [ReadOnly(true)] [DisplayName("Versie")] public object version_date { get; set; } [ColumnAttribute(IsDbGenerated = true)] public object entity_id; }

  • java setting resolution and print size for an Image

    - by Ingrid
    I wrote a program that generates a BufferedImage to be displayed on the screen and then printed. Part of the image includes grid lines that are 1 pixel wide. That is, the line is 1 pixel, with about 10 pixels between lines. Because of screen resolution, the image is displayed much bigger than that, with several pixels for each line. I'd like to draw it smaller, but when I scale the image (either by using Image.getScaledInstance or Graphics2D.scale), I lose significant amounts of detail. I'd like to print the image as well, and am dealing with the same problem. In that case, I am using this code to set the resolution: HashPrintRequestAttributeSet set = new HashPrintRequestAttributeSet(); PrinterResolution pr = new PrinterResolution(250, 250, ResolutionSyntax.DPI); set.add(pr); job.print(set); which works to make the image smaller without losing detail. But the problem is that the image is cut off at the same boundary as if I hadn't set the resolution. I'm also confused because I expected a larger number of DPI to make a smaller image, but it's working the other way. I'm using java 1.6 on Windows 7 with eclipse.

  • Java, How to Instance HttpCookie from a String, any convenient ways?

    - by user435657
    Hi all, I have got a cookie string from HTTP response header like the following line: name=value; path=/; domain=.g.cn; expire=... I can parse the above line to key-value pairs, and, also it's easy to set the name and value to HttpCookie instance as this pair comes the first. But how to set the other pairs since I don't know which set-method corresponds to the name of the next name-value pair. Traverse all possible keys a cookie may contian and call the matched set-method, like below snippet? if (key.equalsIgnoreCase("path")) cookie.setPath(value); else if (key.equalsIgnoreCase("domain")) cookie.setDomain(value); That's foolish, any convenient ways? Thanks in advance.

  • Universal control - simple question about dock and anchor

    - by Vytas999
    I use Visual Studio .NET to develop internal applications. I create a Windows control that will display custom status bar information. Different developers will use the control to display the same information in many different applications. The control must always be displayed at the bottom of the parent form in every application. It must always be as wide as the form. When the form is resized, the control should be resized and repositioned accordingly. How should I do that in the best way and why? A)Create a property to allow the developers to set the Dock property of the control. Set the default value of the property to AnchorStyle.Bottom. B) Create a property to allow the developer to set the Anchor property of the control. Set the default value of the property to AnchorStyle.Bottom.

  • jQuery cookie behaves differently on local machine vs production server

    - by user1810414
    I'm setting a jQuery cookie for some site javascript effects. I'm setting expiration date to 30 days. On local development machine cookie expiration is set properly, whereas on production expiration is being set to end of session. After inspecting the created cookies with web develoer tools, everything is identical except production machine cookie is marked as "session cookie" and setting expiration is disallowed, while cookie created on local development machine is not set to "session" and expiration date is editable. Is there a way to make production machine cookie accept the expiration date? This is how I set the cookie: $.cookie('skip_animation','skip', 2592000); Using jQuery 1.6.4 (legacy site) All browsers behave the same way

  • What does a forward slash before a pipe in cmd do to remove the line ending of an echo?

    This code: @echo off echo/|set /p ="Executing backup...." echo/|set /p =" backup procedure" ... came from Echoing in the same line and produces the below output in a cmd window: Executing backup....backup procedure However, I cant seem to find an explanation through google on what the forward slash does to the ¿pipe? to cause set's output to be echoed to the console / stdout If anyone could also suggest a good website for learning more about cmd / cmd programs' features like this, it would be appreciated.

  • Asp.net MVC - Model binding image button

    - by big dave
    I've got a very complex form and i'm using the MVC model binding to capture all the information I've got it set up to capture all the different submissions that can happen as there are about 10 different submit buttons on the form, and there are also 2 image buttons I tried to get a bit clever (or so i thought) with capturing the image button submissions, and have created a child class so that i can capture the x value that's returned public class ImageButtonViewData { public int x { get; set; } public string Value { get; set; } } The parent class looks something like this public class ViewDataObject { public ImageButtonViewData ImageButton { get; set; } public ViewDataObject(){ this.ImageButton = new ImageButton(); } } The html for the image button then looks like <input type="image" id="ViewDataObject_ImageButton" name="ViewDataObject.ImageButton" /> This works fine in all browsers except for Chrome. When i debug it in chrome, the Request.Form object contains the values that i would expect, but after the model binding has occurred, the ImageButton property on the ViewDataObject has been set to null The only difference that i can see between the submission values is that Chrome passes the x as lower case (ViewDataObject.ImageButton.x) and IE passes it as upper case (ViewDataObject.ImageButton.X) but i didn't think that model binding took any notice of casing on property names Does anyone have any ideas ?

  • What C# container is most resource-efficient for existence for only one operation?

    - by ccornet
    I find myself often with a situation where I need to perform an operation on a set of properties. The operation can be anything from checking if a particular property matches anything in the set to a single iteration of actions. Sometimes the set is dynamically generated when the function is called, some built with a simple LINQ statement, other times it is a hard-coded set that will always remain the same. But one constant always exists: the set only exists for one single operation and has no use before or after it. My problem is, I have so many points in my application where this is necessary, but I appear to be very, very inconsistent in how I store these sets. Some of them are arrays, some are lists, and just now I've found a couple linked lists. Now, none of the operations I'm specifically concerned about have to care about indices, container size, order, or any other functionality that is bestowed by any of the individual container types. I picked resource efficiency because it's a better idea than flipping coins. I figured, since array size is configured and it's a very elementary container, that might be my best choice, but I figure it is a better idea to ask around. Alternatively, if there's a better choice not out of resource-efficiency but strictly as being a better choice for this kind of situation, that would be nice as well.

  • What is the appropriate granularity in building a ViewModel?

    - by JasCav
    I am working on a new project, and, after seeing some of the difficulties of previous projects that didn't provide enough separation of view from their models (specifically using MVC - the models and views began to bleed into each other a bit), I wanted to use MVVM. I understand the basic concept, and I'm excited to start using it. However, one thing that escapes me a bit - what data should be contained in the ViewModel? For example, if I am creating a ViewModel that will encompass two pieces of data so they can be edited in a form, do I capture it like this: public PersonAddressViewModel { public Person Person { get; set; } public Address Address { get; set; } } or like this: public PersonAddressViewModel { public string FirstName { get; set; } public string LastName { get; set; } public string StreetName { get; set; } // ...etc } To me, the first feels more correct for what we're attempting to do. If we were doing more fine grain forms (maybe all we were capturing was FirstName, LastName, and StreetAddress) then it might make more sense to go down to that level. But, I feel like the first is correct since we're capturing ALL Person data in the form and ALL Address data. It seems like it doesn't make sense (and a lot of extra work) to split things apart like that. Appreciate any insight.

  • Oracle global_names DELETE problem

    - by jyzuz
    I'm using a database link to execute a DELETE statement on another DB, but the DB link name doesn't conform to global naming, and this requirement cannot change. Also I have global_names set to false, and cannot be changed either. When I try to use these links however, I receive: ORA-02069: - global_names parameter must be set to TRUE for this operation Cause: A remote mapping of the statement is required but cannot be achieved because GLOBAL_NAMES should be set to TRUE for it to be achieved. - Action: Issue `ALTER SESSION SET GLOBAL_NAMES = TRUE` (if possible) What is the alternative action when setting global_names=true is not possible? Cheers, Jean

  • Is there a way to specify a per-host deploy_to path with Capistrano?

    - by Chad Johnson
    I have searched and searched and asked a question already and have not received a clear answer. I have the following deploy script (snippet): set :application, "testapplication" set :repository, "ssh://domain.com//srv/hg/#{application}" set :scm, :mercurial set :deploy_to, "/srv/www/#{application}" role :web, "domain1.com", "domain2.com" role :app, "domain1.com", "domain2.com" role :db, "domain1.com", :primary => true, :norelease => true role :db, "domain2.com", :norelease => true As you see, I have set deploy_to to a specific path. And, I also have specified multiple web servers. However, each web server should have a different deployment path. I want to be able to run "cap deploy" and deploy to all hosts in one shot. I am NOT trying to deploy to staging and then to production. This is all production. My question is: how exactly do I specify a path per server? I have read the "Roles" documentation for Capistrano, and this is unclear. Can someone please post a deploy file example? I have read the documentation, and it is unclear how to do this. Does anyone know? Am I crazy? Am I thinking of this wrong or something? No answers anywhere online. Nowhere. Nothing. Please, someone help.

  • PostgreSQL function to iterate through/act on many rows with state

    - by Claudiu
    I have a database with columns looking like: session | order | atype | amt --------+-------+-------+----- 1 | 0 | ADD | 10 1 | 1 | ADD | 20 1 | 2 | SET | 35 1 | 3 | ADD | 10 2 | 0 | SET | 30 2 | 1 | ADD | 20 2 | 2 | SET | 55 It represents actions happening. Each session starts at 0. ADD adds an amount, while SET sets it. I want a function to return the end value of a session, e.g. SELECT session_val(1); --returns 45 SELECT session_val(2); --returns 55 Is it possible to write such a function/query? I don't know how to do any iteration-like things with SQL, or if it's possible at all.

  • Access.Application.CurrentDb is Nothing?

    - by Allain Lalonde
    I'm at a loss to explain this one: I'm getting an error "91" (Object or With block not set) on the second line below: Dim rs As DAO.Recordset Set rs = CurrentDb.OpenRecordset("SELECT * FROM employees") The following also causes it: Set rs = CurrentDb.OpenRecordset("employees") Executing ?CurrentDb.Name alone in the immediate window causes the error as well. Now, clearly the database is open since I'm editing the form within it, so what can cause this error here?

  • Concatenating a Text in front of Individual Database Records with Tcl

    - by DFM
    Hello: In short, currently I am using the following code to pull records from multiple tables in a Sqlite Db and insert them in a single combobox ($SearchBar): set SrchVals1 [db eval {SELECT DISTINCT Stitle From Subcontract Order By Stitle ASC}] set SrchVals2 [db eval {... set SrchVals3 ... set SrchValsALL [concat $SrchVals1 $SrchVals2 $SrchVals3] $SearchBar configure -value $SrchValsAll For the variable "SrchVals1", I am trying to figure out a way to concatenate the text "Sub: " to each individual record in SrchVals1. For example, if SrchVals1 shows the following records in the combobox: First Title Second Title Third Title I would like to concatenate so that the records in the combobox look like this: Sub: First Title Sub: Second Title Sub: Third Title I understand that I might have to use a foreach statement; however, I am having no luck writing one that adds "Sub: " in front of each record, as opposed to one. This seems like something that should be pretty easy, but I cannot seem to figure it out. Does anyone know how I can achieve these results? Thank you, DFM

  • Using boost::iterator_adaptor

    - by Neil G
    I wrote a sparse vector class (see #1, #2.) I would like to provide two kinds of iterators: The first set, the regular iterators, can point any element, whether set or unset. If they are read from, they return either the set value or value_type(), if they are written to, they create the element and return the lvalue reference. Thus, they are: Random Access Traversal Iterator and Readable and Writable Iterator The second set, the sparse iterators, iterate over only the set elements. Since they don't need to lazily create elements that are written to, they are: Random Access Traversal Iterator and Readable and Writable and Lvalue Iterator I also need const versions of both, which are not writable. I can fill in the blanks, but not sure how to use boost::iterator_adaptor to start out. Here's what I have so far: class iterator : public boost::iterator_adaptor< iterator // Derived , value_type* // Base , boost::use_default // Value , boost::?????? // CategoryOrTraversal > class sparse_iterator : public boost::iterator_adaptor< iterator // Derived , value_type* // Base , boost::use_default // Value , boost::random_access_traversal_tag? // CategoryOrTraversal >
