  • Extend base class properties

    - by user1888033
    I need your help to extend my base class, here is the similar structure i have. public class ShowRoomA { public audi AudiModelA { get; set; } public benz benzModelA { get; set; } } public class audi { public string Name { get; set; } public string AC { get; set; } public string PowerStearing { get; set; } } public class benz { public string Name { get; set; } public string AC { get; set; } public string AirBag { get; set; } public string MusicSystem { get; set; } } //My Implementation class like this class Main() { private void UpdateDetails() { ShowRoomA ojbMahi = new ShowRoomA(); GetDetails( ojbMahi ); // this works fine } private void GetDetails(ShowRoomA objShowRoom) { objShowRoom = new objShowRoom(); objShowRoom.audi = new audi(); objShowRoom.audi.Name = "AUDIMODEL94CD698"; objShowRoom.audi.AC = "6 TON"; objShowRoom.audi.PowerStearing = "Electric"; objShowRoom.benz= new benz(); objShowRoom.audi.Name = "BENZMODEL34LCX"; objShowRoom.audi.AC = "8 TON"; objShowRoom.audi.AirBag = "Two (1+1)"; objShowRoom.audi.MusicSystem = "Poineer 3500W"; } } // Till this cool. // Now I got requirement for ShowRoomB with replacement of old audi and benz with new models and new other brand cars also added. // I don't want to modify GetDetails() method. by reusing this method additional logic i want to apply to my new extended model. // Here I struck in designing my new model of ShowRoomB (base of ShowRoomA) ... I have tried some thing like... but not sure. public class audiModelB:audi { public string JetEngine { get; set; } } public class benzModelB:benz { public string JetEngine { get; set; } } public class ShowRoomB { public audiModelB AudiModelB { get; set; } public benzModelB benzModelB { get; set; } } // My new code to Implementation class like this class Main() { private void UpdateDetails() { ShowRoomB ojbNahi = new ShowRoomB(); GetDetails( ojbNahi ); // this is NOT working! I know this object does not contain base class directly, still some what i want fill my new model with old properties. Kindly suggest here } } Can any one please give me solutions how to achieve my extending requirement for base class "ShowroomA" Really appreciated your time and suggestions. Thanks in advance,

  • how to generate JMX MXBean compatible java class model from JAXB?

    - by yucubby
    From the JMX MXBean specification, a java class type J must satisfy Either if J has at least one public constructor with a ConstructorProperties annotation, Or if J has a public no-arg constructor, and for every getter in J with type T and name N there is a corresponding setter with the same name and type So how can I use JAXB to generate JAVA class model which satisfy the MXBean constrain?

  • build-helper-maven-plugin add-source does not working when trying to add linked resources

    - by Julian
    I am new to maven and hit a problem that looks easy in the first place but I already kept me busy for a whole day about and no way to get it working. First as part of running eclipse:eclipse plugin I create a linked folder like below: <linkedResources> <linkedResource> <name>properties</name> <type>2</type> <location>${PARENT-2-PROJECT_LOC}/some_other_project/properties</location> </linkedResource> <linkedResource> <name>properties/messages.properties</name> <type>1</type> <location>${PARENT-2-PROJECT_LOC}/some_other_project/properties/messages.properties</location> </linkedResource> And then I am adding that folder as a source folder like below: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>build-helper-maven-plugin</artifactId> <version>1.7</version> <executions> <execution> <id>add-source</id> <phase>generate-sources</phase> <goals> <goal>add-source</goal> </goals> <configuration> <sources> <source>properties</source> <source>some_real_folder</source> </sources> </configuration> </execution> </executions> </plugin> However when I am looking at the generated .classpath in eclipse the “some_real_folder” is there but the “properties” is not. It looks like by default the build-helper-maven-plugin will check if the folder is there and if it is not it won’t add it. I am using maven 3.0.4 outside eclipse to run the build and I can see in the maven logs something like this: [INFO] Source directory: <some path>\properties added. This is my project structure: project1 \-- properties (this is the real folder) project2 \-- some_real_folder \-- properties (this is the link resource pointing to the project1/properties folder) All I need is to have both "some_real_folder" and the linked resource "properties" added to the .classpath of the project2

  • In MVC framworks (such as Ruby on Rails), do usually Model spell as singular and controller and view

    - by Jian Lin
    I usually see Ruby on Rails books using script/generate model Story name:string link:string which is a singular Story, while when it is controller script/generate controller Stories index then the Story now is Stories, which is plural. Is this a standard on Ruby on Rails? Is it true in other MVC frameworks too, like CakePHP, Symfony, Django, or TurboGears? I see that in the book Rails Space, the controller is also called User, which is the same as the model name, and it is the only exception I see.

  • How to Access a Button present inside a Custom Control, from the implementing page?

    Hi, I have my generic.xaml containing the following code: <ControlTemplate TargetType="local:customVideoControl"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="600"/> <RowDefinition Height="200"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="200"/> <ColumnDefinition Width="200"/> <ColumnDefinition Width="200"/> </Grid.ColumnDefinitions> <MediaElement x:Name="customMediaPlayer" Source="{TemplateBinding CustomMediaSource}" HorizontalAlignment="Center" VerticalAlignment="Center" Height="{TemplateBinding Height}" Width="{TemplateBinding Width}" Grid.Row="0" Grid.ColumnSpan="3" /> <ToggleButton x:Name="playPauseBtn" Height="50" Width="50" Content="Pause" Grid.Row="1" Grid.Column="0"/> <Button x:Name="prevBtn" Height="50" Width="50" Content="Prev" Grid.Row="1" Grid.Column="1"/> <Button x:Name="nextBtn" Height="50" Width="50" Content="Next" Grid.Row="1" Grid.Column="2"/> </Grid> </ControlTemplate> Now on applyTemplate , I am accessing the controls like below: public override void OnApplyTemplate() { base.OnApplyTemplate(); ToggleButton playPauseBtn = GetTemplateChild("playPauseBtn") as ToggleButton; Button prevBtn= GetTemplateChild("prevBtn") as Button; Button nextBtn = GetTemplateChild("nextBtn") as Button; MediaElement customMediaPlayer = GetTemplateChild("customMediaPlayer") as MediaElement; playPauseBtn.Checked += (obj, Args) => { customMediaPlayer.Pause(); playPauseBtn.Content = "Play"; }; playPauseBtn.Unchecked += (obj, Args) => { customMediaPlayer.Play(); playPauseBtn.Content = "Pause"; }; nextBtn.Click += (obj, Args) => { customMediaPlayer.Source=new Uri(CustomMediaSource.ToString(),UriKind.RelativeOrAbsolute); }; prevBtn.Click += (obj, Args) => { customMediaPlayer.Source = new Uri(CustomMediaSource.ToString(), UriKind.RelativeOrAbsolute); }; } Now I want acccess the nextBtn, in the page where I am implementing like CustomVideoControl myVControl=new CustomVideoControl(); This will create the instance of the control, but I want to do something on the click of next and previous button, thta is present inside the CustomVideoControl in generic.xaml. Any help will be greatly appreciated. Thanks, Subhen

  • Select options not showing in IE

    - by donkapone
    I have a dynamically generated select with some options and it shows the options fine in normal browsers, but its empty options in IE. Here's the generated HTML: <select name="0" id="custom_0" style="border-bottom: #c0cedb 1px solid; border-left: #c0cedb 1px solid; background-color: #ededed; width: 280px; font-size: 0.87em; border-top: #c0cedb 1px solid; border-right: #c0cedb 1px solid"> <option id="1000" value="0" name="00">1x2GB ECC DDRIII 2GB ECC DDRIII</option> <option id="1001" value="10" name="01">2x2GB ECC DDRIII 4GB ECC DDRIII (+10.00 €)</option> </select> I can't really show you the javascript, since there's so much of it and I would be able to make it simple just for a demo. Maybe you had some of you would've had a similar experience and could figure this one out. Thanks I've added some javascript: $('#custom_order').append('<tr id="custom_'+category+'_row"><td'+padding+'>'+header+'<select id="custom_'+category+'" name="'+category+'" style="background-color:#EDEDED;border:1px solid #C0CEDB;width:280px;font-size:0.87em"></select>'+plusspan+'</td></tr>'); for (var i=0;i<components[category]['value'].length;i++){ $('#custom_'+category).append('<option id="'+components[category]['value'][i]['id']+'" value="'+components[category]['value'][i]['price']+'"></option>'); removals(category,i); dependencies(category,i); selectInput(category); } getDiff(category); getDiff() function adds the values to the options with html() function. The weird thing is, if I alert the html of the option just after the getDiff() function, it shows the value filled out. And it I put the getDiff() function in the for loop where the options are generated, it fills the values and shows them in IE, just not the last one. I'm calling getDiff() outside the loop for optimization, and since I can add the values later after all the options are generated. Well at least I thought I could, since it works on Firefox and Chrome.

  • Silverlight: Binding to a LayoutRoot value from within a DataTemplate

    - by Rosarch
    I have a DataTemplate for a ListBox, where I have several controls that bind to an item. I would also like to bind to a value on LayoutRoot.DataContext. I'm unsure of how to do this. <!--LayoutRoot is the root grid where all page content is placed--> <StackPanel x:Name="LayoutRoot" Background="Transparent"> <ListBox ItemsSource="{Binding Items}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding}" /> <TextBlock Text="{Binding ElementName=LayoutRoot, Path=DataContext.Foo}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </StackPanel> public partial class MainPage : PhoneApplicationPage { public string Foo { get { return "the moon"; } } private int startIndex = 1; private IList<string> _data = new List<string>() { "foo", "bar", "baz" }; public IList<string> Items { get { return _data; } } // Constructor public MainPage() { InitializeComponent(); LayoutRoot.DataContext = this; } } This doesn't work; only the _data items are displayed. The following binding errors appear in the Debug output: System.Windows.Data Error: BindingExpression path error: 'Foo' property not found on 'foo' 'System.String' (HashCode=1502598398). BindingExpression: Path='DataContext.Foo' DataItem='System.Windows.Controls.Border' (HashCode=78299055); target element is 'System.Windows.Controls.TextBlock' (Name=''); target property is 'Text' (type 'System.String')..

BindingExpression: Path='DataContext.Foo' DataItem='System.Windows.Controls.Border' (HashCode=78298703); target element is 'System.Windows.Controls.TextBlock' (Name=''); target property is 'Text' (type 'System.String')..

Do I have a syntax error somewhere? Update I'm aiming for something that looks like this: foo the moon bar the moon baz the moon Instead, all I'm getting is: foo bar baz

  • How do I specify attributes for a Html.TextBox helper while maintaing the value retreival from ViewD

    - by BigJoe714
    I am using the Html.TextBox helper to create textboxes. I want to set attributes on the textbox, which I understand is done using the following overload: Html.TextBox (string name, object value, object htmlAttributes) However, I want to maintain the functionality where the html helper automatically uses the value from either ViewData or ViewData.Model and I do not see a way to just specify the name and the htmlAttributes. Is this possible?

  • problem with logout script in php

    - by user225269
    I'm a beginner in php, and I am trying to create a login and logout. But I am having problems in logging out. My logout just calls for the login form which is this: <? session_start(); session_destroy(); ?> <table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC"> <tr> <form name="form1" method="post" action="checklogin.php"> <td> <table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF"> <tr> <td colspan="3"><strong>Member Login </strong></td> </tr> <tr> <td width="78">Username</td> <td width="6">:</td> <td width="294"><input name="myusername" type="text" id="myusername"></td> </tr> <tr> <td>Password</td> <td>:</td> <td><input name="mypassword" type="text" id="mypassword"></td> </tr> <tr> <td>&nbsp;</td> <td>&nbsp;</td> <td><input type="submit" name="Submit" value="Login"></td> </tr> </table> </td> </form> </tr> </table> My problem is, when I try to press the back button in the browser. Whoever user is using it can still access what is not supposed to be accessed when a user hasn't logged in. Do I need to add a code on the user page? I have this code on the user page: <? session_start(); if(!session_is_registered(myusername)){ header("location:main_login.php"); } ?> What can you recommend that I would do so that a script will prompt to enter the username and password again when a user clicks on the back button.
