  • What's the best method to be overloaded in ViewPage for inserting some script to all ViewPage?

    - by Soul_Master
    I want to insert some script that is required for my JavaScript library in all view pages. I know that Asp.net MVC is built on Asp.net Framework. Therefore, I can override many methods in “System.Web.UI.Page” class that is a parent of “System.Web.Mvc.ViewPage” class. Nevertheless, I can do it by override Render method but it makes all view pages be invalid for XHTML 1.0 strict. Correct JavaScript must be placed in header tag of HTML document. public class ViewPage<TModel> : ViewPage where TModel : class { protected override void Render(System.Web.UI.HtmlTextWriter writer) { base.Render(writer); writer.Write("<script type='text/javascript>applicationPath = window.applicationPath = 'somePath';</script>"); } } Thanks, PS. I know I can create some code in each master page for doing that. However, it is a quite complicate for other developers to start using my JavaScript source code.

  • WebView inside Tab hiding the tabWidgets

    - by brockoli
    I'm having trouble with a WebView always filling the full screen and thus covering my tabs. Here is my code for the tabhost.. public class tabNZBMobile extends TabActivity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Reusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, NewzbinMobile.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("search").setIndicator("Search", res.getDrawable(R.drawable.ic_tab_search)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, sabnzbWeb.class); spec = tabHost.newTabSpec("sabnzbweb").setIndicator("SabNZBd", res.getDrawable(R.drawable.ic_tab_sabnzbweb)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTabByTag("search"); }} My first tab (NewzbinMobile.class) displays correctly, it's just a relativelayout. But my second tab is an activity showing a webview and it is showing, but using the whole screen, covering my tabs. Here is the code for my second tab. public class sabnzbWeb extends Activity { WebView mWebView; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); String sabNZBurl = new String("http://test.server.org:8080/m"); mWebView = new WebView(this); mWebView.getSettings().setJavaScriptEnabled(true); setContentView(mWebView); mWebView.loadUrl(sabNZBurl); }}

  • How to create a rails habtm that deletes/destroys without error?

    - by Bradley
    I created a simple example as a sanity check and still can not seem to destroy an item on either side of a has_and_belongs_to_many relationship in rails. Whenever I try to delete an object from either table, I get the dreaded NameError / "uninitialized constant" error message. To demonstrate, I created a sample rails app with a Boy class and Dog class. I used the basic scaffold for each and created a linking table called boys_dogs. I then added a simple before_save routine to create a new 'dog' any time a boy was created and establish a relationship, just to get things setup easily. dog.rb class Dog < ActiveRecord::Base has_and_belongs_to_many :Boys end boy.rb class Boy < ActiveRecord::Base has_and_belongs_to_many :Dogs def before_save self.Dogs.build( :name => "Rover" ) end end schema.rb ActiveRecord::Schema.define(:version => 20100118034401) do create_table "boys", :force => true do |t| t.string "name" t.datetime "created_at" t.datetime "updated_at" end create_table "boys_dogs", :id => false, :force => true do |t| t.integer "boy_id" t.integer "dog_id" t.datetime "created_at" t.datetime "updated_at" end create_table "dogs", :force => true do |t| t.string "name" t.datetime "created_at" t.datetime "updated_at" end end I've seen lots of posts here and elsewhere about similar problems, but the solutions are normally using belongs_to and the plural/singular class names being confused. I don't think that is the case here, but I tried switching the habtm statement to use the singular name just to see if it helped (with no luck). I seem to be missing something simple here. The actual error message is: NameError in BoysController#destroy uninitialized constant Boy::Dogs The trace looks like: /Library/Ruby/Gems/1.8/gems/activesupport-2.3.4/lib/active_support/dependencies.rb:105:in const_missing' (eval):3:indestroy_without_callbacks' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.4/lib/active_record/callbacks.rb:337:in destroy_without_transactions' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.4/lib/active_record/transactions.rb:229:insend' ... Thanks.

  • Year split in Quarters using basic jQuery

    - by Alexander Corotchi
    Hi, I have a interesting question: I want to split the year into 4 quarters. What is the idea, A quarter can be different: The HTML Code: <div class="quarterBody"> <span>04-29-2010</span> <span>06-29-2010</span> <span>08-29-2010</span> </div> jQuery (javascript) is total wrong, I hope that w: $(document).ready(function(){ var quarter1 = to make interval (01-01-2010 to 03-31-2010); var quarter2 = to make interval (03-01-2010 to 06-31-2010); var quarter3 = to make interval (06-01-2010 to 09-31-2010); var quarter4 = to make interval (09-01-2010 to 12-31-2010); ... $(".quarterBody span").each(function(){ var date = Date.parse($(this).text()); //to apply some magic code $(this).addClass(quarterNumber); }); }); OUTPUT: <div class="quarterBody"> <span class="Quarter1">02-29-2010</span> <span class="Quarter2">04-29-2010</span> <span class="Quarter3">08-29-2010</span> ... </div> I know right now it is a stupid way, but I hope that somebody can help me, or suggest an idea how to do that in a better way!! Thanks!

  • Spring: PropertyPlaceHolderConfigurer to set values for non-string/integer properties

    - by babyangel86
    Hi, All the examples I have seen where the PropertyPlaceHolderConfigurer is used seem to be setting simple values like Strings and ints. How do you use the PPC to set the values of classes. E.g. If i had a class signature Source(String name, DistributionSample batch, DistributionSample delay) How would I go about setting the batch and delay properties. There is also a small catch. DistributionSample is an abstract class. On the bright side, The class that is using the propertyPlaceHolder knows the beanName of the "Solid" class that needs to be instantiated. Any help would be much appreciated.

  • python: how to design a container with elements that must reference their container

    - by Luke404
    (the title is admittedly not that great. Please forgive my English, this is the best I could think of) I'm writing a python script that will manage email domains and their accounts, and I'm also a newby at OOP design. My two (related?) issues are: the Domain class must do special work to add and remove accounts, like adding/removing them to the underlying implementation how to manage operations on accounts that must go through their container To solve the former issue I'd add a factory method to the Domain class that'll build an Account instance in that domain, and a 'remove' (anti-factory?) method to handle deletions. For the latter this seems to me "anti-oop" since what would logically be an operation on an Account (eg, change password) must always reference the containing Domain. Seems to me that I must add to the Account a reference back to the Domain and use that to get data (like the domain name) or call methods on the Domain class. Code example (element uses data from the container) that manages an underlying Vpopmail system: class Account: def __init__(self, name, password, domain): self.name = name self.password = password self.domain = domain def set_password(self, password): os.system('vpasswd %s@%s %s' % (self.name, self.domain.name, password) self.password = password class Domain: def __init__(self, domain_name): self.name = domain_name self.accounts = {} def create_account(self, name, password): os.system('vadduser %s@%s %s' % (name, self.name, password)) account = Account(name, password, self) self.accounts[name] = account def delete_account(self, name): os.system('vdeluser %s@%s' % (name, self.name)) del self.accounts[name] another option would be for Account.set_password to call a Domain method that would do the actual work - sounds equally ugly to me. Also note the duplication of data (account name also as dict key), it sounds logical (account names are "primary key" inside a domain) but accounts need to know their own name.

  • Datagrid using usercontrol

    - by klawusel
    Hello I am fighting with this problem: I have a usercontrol which contains a textbox and a button (the button calls some functions to set the textbox's text), here is the xaml: <UserControl x:Class="UcSelect" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Name="Control1Name" <Grid x:Name="grid1" MaxHeight="25"> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition Width="25"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="25"/> </Grid.RowDefinitions> <TextBox x:Name="txSelect" Text="{Binding UcText, Mode=TwoWay}" /> <Button x:Name="pbSelect" Background="Red" Grid.Column="1" Click="pbSelect_Click">...</Button> </Grid> And here the code behind: Partial Public Class UcSelect Private Shared Sub textChangedCallBack(ByVal [property] As DependencyObject, ByVal args As DependencyPropertyChangedEventArgs) Dim UcSelectBox As UcSelect = DirectCast([property], UcSelect) End Sub Public Property UcText() As String Get Return GetValue(UcTextProperty) End Get Set(ByVal value As String) SetValue(UcTextProperty, value) End Set End Property Public Shared ReadOnly UcTextProperty As DependencyProperty = _ DependencyProperty.Register("UcText", _ GetType(String), GetType(UcSelect), _ New FrameworkPropertyMetadata(String.Empty, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, New PropertyChangedCallback(AddressOf textChangedCallBack))) Public Sub New() InitializeComponent() grid1.DataContext = Me End Sub Private Sub pbSelect_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) 'just demo UcText = UcText + "!" End Sub End Class The UserControl works fine when used as a single control in this way: <local:UcSelect Grid.Row="1" x:Name="ucSingle1" UcText="{Binding FirstName, Mode=TwoWay}"/> Now I wanted to use the control in a custom datagrid column. As I like to have binding support I choosed to derive from DataGridtextColumn instead of using a DataGridTemplateColumn, here is the derived column class: Public Class DerivedColumn Inherits DataGridTextColumn Protected Overloads Overrides Function GenerateElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oElement = MyBase.GenerateElement(oCell, oDataItem) Return oElement End Function Protected Overloads Overrides Function GenerateEditingElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oUc As New UcSelect Dim oBinding As Binding = CType(Me.Binding, Binding) oUc.SetBinding(UcSelect.UcTextProperty, oBinding) Return oUc End Function End Class The column is used in xaml in the following way: <local:DerivedColumn Header="Usercontrol" Binding="{Binding FirstName, Mode=TwoWay}"></local:DerivedColumn> If I start my program all seems to be fine, but changes I make in the custom column are not reflected in the object (property "FirstName"), the changes are simply rolled back when leaving the cell. I think there must be something wrong with my GenerateEditingElement code, but have no idea ... Any Help would really be appreciated Regards Klaus

  • Uploading to TwitVid using x_verify_credentials_authorization

    - by deepa
    Hi, I am developing an iPhone application that uploads videos to TwitVid using the library TwitVid-iPhone-OAuth3. I have selected this library since Twitter is shifting to OAuth mechanism of authentication. 1) Does this new library allows to upload without user-name and password parameters? 2) I am using the following steps for uploading videos (assumed that new library allows to upload without user-name and password parameters). But, I am getting the error 'Incorrect Signature'. I am not able to identify the mistake that I am doing here. Could you please help me out to solve this problem. Authenticate the app using OAuth (MGTwitterEngine etc) which redirects the user to the web-page asking for log-in and app authentication. If the user authenticates the app, access token will obtained as final step. Upload the video to TwitVid using the following code snippet: OAuth *authorizer = [[OAuth alloc] initWithConsumerKey: @"my_consumer_key" andConsumerSecret: @"my_consumer_secret"]; authorizer.oauth_token = //The key-part of the access token obtained in step 2 authorizer.oauth_token_secret = //The secret-part of the access token obtained in step 2 authorizer.oauth_token_authorized = YES; //Since authenticated in steps 1 and 2 NSString *authHeader = [authorizer oAuthHeaderForMethod: @"POST" andUrl: @"https://api.twitter.com/1/account/verify_credentials.xml" andParams: nil]; twitVid = [[TwitVid alloc] init]; [mTwitVid setDelegate: self]; [mTwitVid authenticateWithXVerifyCredentialsAuthorization: authHeader xAuthServiceProvider: nil]; Thanks and Regards, Deepa

  • VPython in Eclipse - thinks it has the wrong architecture type.

    - by Duncan Tait
    Evening, So I've recently installed VPython on my MacBook (OS X, Snow Leopard) - and it works absolutely fine in IDLE and from the command line (interactive mode). However, eclipse has issues. Firstly it couldn't find it (which is a bit of an issue actually with all these 'easy install' python modules - when they don't tell you where they actually install to!) but I searched it out in the depths of Library\Frameworks... and added that to the System PYTHONPATH listbox in Eclipse. Now it can find it, but it says the following: Traceback (most recent call last): File "/Users/duncantait/dev/workspace/Network_Simulation/src/Basic/Net_Sim1.py", line 15, in <module> import visual File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/__init__.py", line 59, in <module> import cvisual ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/cvisual.so, 2): no suitable image found. Did find: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/cvisual.so: mach-o, but wrong architecture I am guessing that VPython might not be built for a 64-bit architecture (Intel), but the fact remains that it works in both IDLE and command prompt... So there must be a way to configure Eclipse to run it right? (Wishful thinking). Thanks for any help! Duncan

  • Writing JSON with XSLT

  • No compile errors when reference added, but errors seen upon build

    - by cjs
    A solution was just converted from VS 2008 to VS 2010. My VS 2010 build is failing with the popular "The type or namespace X could not be found". When I go to the project and go to Add References and add the appropriate project dll, the class name appears in blue text as if .NET found the correct class. However, when I go to the Build menu and select "Build Solution" I get the "namespace not found error" and the class name is no longer blue. Thanks.

  • ItemsControl ItemTemplate Binding

    - by Wonko the Sane
    Hi All, In WPF4.0, I have a class that contains other class types as properties (combining multiple data types for display). Something like: public partial class Owner { public string OwnerName { get; set; } public int OwnerId { get; set; } } partial class ForDisplay { public Owner OwnerData { get; set; } public int Credit { get; set; } } In my window, I have an ItemsControl with the following (clipped for clarity): <ItemsControl ItemsSource={Binding}> <ItemsControl.ItemTemplate> <DataTemplate> <local:MyDisplayControl OwnerName={Binding OwnerData.OwnerName} Credit={Binding Credit} /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> I then get a collection of display information from the data layer, and set the DataContext of the ItemsControl to this collection. The "Credit" property gets displayed correctly, but the OwnerName property does not. Instead, I get a binding error: Error 40: BindingExpression path error: 'OwnerName' property not found on 'object' ''ForDisplay' (HashCode=449124874)'. BindingExpression:Path=OwnerName; DataItem='ForDisplay' (HashCode=449124874); target element is 'TextBlock' (Name=txtOwnerName'); target property is 'Text' (type 'String') I don't understand why this is attempting to look for the OwnerName property in the ForDisplay class, rather than in the Owner class from the ForDisplay OwnerData property. Edit It appears that it has something to do with using the custom control. If I bind the same properties to a TextBlock, they work correctly. <ItemsControl ItemsSource={Binding}> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel> <local:MyDisplayControl OwnerName={Binding OwnerData.OwnerName} Credit={Binding Credit} /> <TextBlock Text="{Binding OwnerData.OwnerName}" /> <TextBlock Text="{Binding Credit}" /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> Thanks, wTs

  • JSON.Net and Linq

    - by user1745143
    I'm a bit of a newbie when it comes to linq and I'm working on a site that parses a json feed using json.net. The problem that I'm having is that I need to be able to pull multiple fields from the json feed and use them for a foreach block. The documentation for json.net only shows how to pull just one field. I've done a few variations after checking out the linq documentation, but I've not found anything that works best. Here's what I've got so far: WebResponse objResponse; WebRequest objRequest = HttpWebRequest.Create(url); objResponse = objRequest.GetResponse(); using (StreamReader reader = new StreamReader(objResponse.GetResponseStream())) { string json = reader.ReadToEnd(); JObject rss = JObject.Parse(json); var postTitles = from p in rss["feedArray"].Children() select (string)p["item"], //These are the fields I need to also query //(string)p["title"], (string)p["message"]; //I've also tried this with console.write and labeling the field indicies for each pulled field foreach (var item in postTitles) { lbl_slides.Text += "<div class='slide'><div class='slide_inner'><div class='slide_box'><div class='slide_content'></div><!-- slide content --></div><!-- slide box --></div><div class='rotator_photo'><img src='" + item + "' alt='' /></div><!-- rotator photo --></div><!-- slide -->"; } } Has anyone seen how to pull multiple fields from a json feed and use them as part of a foreach block (or something similar?

  • Jquery Accordion and Fading

  • Python: unable to inherit from a C extension.

    - by celil
    I am trying to add a few extra methods to a matrix type from the pysparse library. Apart from that I want the new class to behave exactly like the original, so I chose to implement the changes using inheritance. However, when I try from pysparse import spmatrix class ll_mat(spmatrix.ll_mat): pass this results in the following error TypeError: Error when calling the metaclass bases cannot create 'builtin_function_or_method' instances What is this causing this error? Is there a way to use delegation so that my new class behaves exactly the same way as the original?

  • Generic structure for performing string conversion when data binding.

    - by Rohan West
    Hi there, a little while ago i was reading an article about a series of class that were created that handled the conversion of strings into a generic type. Below is a mock class structure. Basically if you set the StringValue it will perform some conversion into type T public class MyClass<T> { public string StringValue {get;set;} public T Value {get;set;} } I cannot remember the article that i was reading, or the name of the class i was reading about. Is this already implemented in the framework? Or shall i create my own?

  • Should business objects be able to create their own DTOs?

    - by Sam
    Suppose I have the following class: class Camera { public Camera( double exposure, double brightness, double contrast, RegionOfInterest regionOfInterest) { this.exposure = exposure; this.brightness = brightness; this.contrast = contrast; this.regionOfInterest = regionOfInterest; } public void ConfigureAcquisitionFifo(IAcquisitionFifo acquisitionFifo) { // do stuff to the acquisition FIFO } readonly double exposure; readonly double brightness; readonly double contrast; readonly RegionOfInterest regionOfInterest; } ... and a DTO to transport the camera info across a service boundary (WCF), say, for viewing in a WinForms/WPF/Web app: using System.Runtime.Serialization; [DataContract] public class CameraData { [DataMember] public double Exposure { get; set; } [DataMember] public double Brightness { get; set; } [DataMember] public double Contrast { get; set; } [DataMember] public RegionOfInterestData RegionOfInterest { get; set; } } Now I can add a method to Camera to expose its data: class Camera { // blah blah public CameraData ToData() { var regionOfInterestData = regionOfInterest.ToData(); return new CameraData() { Exposure = exposure, Brightness = brightness, Contrast = contrast, RegionOfInterestData = regionOfInterestData }; } } or, I can create a method that requires a special IReporter to be passed in for the Camera to expose its data to. This removes the dependency on the Contracts layer (Camera no longer has to know about CameraData): class Camera { // beep beep I'm a jeep public void ExposeToReporter(IReporter reporter) { reporter.GetCameraInfo(exposure, brightness, contrast, regionOfInterest); } } So which should I do? I prefer the second, but it requires the IReporter to have a CameraData field (which gets changed by GetCameraInfo()), which feels weird. Also, if there is any even better solution, please share with me! I'm still an object-oriented newb.

  • How to configure Spring Security PasswordComparisonAuthenticator

    - by denlab
    I can bind to an embedded ldap server on my local machine with the following bean: <b:bean id="secondLdapProvider" class="org.springframework.security.ldap.authentication.LdapAuthenticationProvider"> <b:constructor-arg> <b:bean class="org.springframework.security.ldap.authentication.BindAuthenticator"> <b:constructor-arg ref="contextSource" /> <b:property name="userSearch"> <b:bean id="userSearch" class="org.springframework.security.ldap.search.FilterBasedLdapUserSearch"> <b:constructor-arg index="0" value="ou=people"/> <b:constructor-arg index="1" value="(uid={0})"/> <b:constructor-arg index="2" ref="contextSource" /> </b:bean> </b:property> </b:bean> </b:constructor-arg> <b:constructor-arg> <b:bean class="com.company.security.ldap.BookinLdapAuthoritiesPopulator"> </b:bean> </b:constructor-arg> </b:bean> however, when I try to authenticate with a PasswordComparisonAuthenticator it repeatedly fails on a bad credentials event: <b:bean id="ldapAuthProvider" class="org.springframework.security.ldap.authentication.LdapAuthenticationProvider"> <b:constructor-arg> <b:bean class="org.springframework.security.ldap.authentication.PasswordComparisonAuthenticator"> <b:constructor-arg ref="contextSource" /> <b:property name="userDnPatterns"> <b:list> <b:value>uid={0},ou=people</b:value> </b:list> </b:property> </b:bean> </b:constructor-arg> <b:constructor-arg> <b:bean class="com.company.security.ldap.BookinLdapAuthoritiesPopulator"> </b:bean> </b:constructor-arg> </b:bean> Through debugging, I can see that the authenticate method picks up the DN from the ldif file, but then tries to compare the passwords, however, it's using the LdapShaPasswordEncoder (the default one) where the password is stored in plaintext in the file, and this is where the authentication fails. Here's the authentication manager bean referencing the preferred authentication bean: <authentication-manager> <authentication-provider ref="ldapAuthProvider"/> <authentication-provider user-service-ref="userDetailsService"> <password-encoder hash="md5" base64="true"> <salt-source system-wide="secret"/> </password-encoder> </authentication-provider> </authentication-manager> On a side note, whether I set the password-encoder on ldapAuthProvider to plaintext or just leave it blank, doesn't seem to make a difference. Any help would be greatly appreciated. Thanks
