• sermyadmin 2.01

  - by lepricon123

  I am able to install sermyadmin 2.0.1 and got everything working. Only user registration is not working. When I register a user the entry goe sin DB etc find but the email is not send to the user. We are using our own smtp server with no authentication. And I am sure there is nothing wrong with the smtp server. I can see that it has received a request from sermyadmin but in the logs Is ee that the FROM adddress is missing. So it is throwing 553 5.1.8 Domain of sender address does not exist. The domain does exist. Here is my resources.xml with all the valid entries. Since I don;t need the smtp authentication which the server is not using, i removed that. <beans xmlns="www.springframework.org/schema/beans" xmlns:xsi="www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" www.springframework.org/schema/beans www.springframework.org/schema/beans/spr...ns-2.0.xsd"> <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host" value="10.100.22.365" /> </bean> <bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage"> <property name="from" value="[email protected]" /> </bean> </beans>

• NHibernate save / update event listeners: listening for child object saves

  - by James Allen

  I have an Area object which has many SubArea children: public class Area { ... public virtual IList<SubArea> SubAreas { get; set; } } he children are mapped as a uni-directional non-inverse relationship: public class AreaMapping : ClassMap<Area> { public AreaMapping() { HasMany(x => x. SubAreas).Not.Inverse().Cascade.AllDeleteOrphan(); } } The Area is my aggregate root. When I save an area (e.g. Session.Save(area) ), the area gets saved and the child SubAreas automatically cascaded. I want to add a save or update event listener to catch whenever my areas and/or subareas are persisted. Say for example I have an area, which has 5 SubAreas. If I hook into SaveEventListeners: Configuration.EventListeners.SaveEventListeners = new ISaveOrUpdateEventListener[] { mylistener }; When I save the area, Mylistener is only fired once only for area (SubAreas are ignored). I want the 5 SubAreas to be caught aswell in the event listener. If I hook into SaveOrUpdateEventListeners instead: Configuration.EventListeners.SaveOrUpdateEventListeners = new ISaveOrUpdateEventListener[] { mylistener }; When I save the area, Mylistener is not fired at all. Strangely, if I hook into SaveEventListeners and SaveOrUpdateEventListeners: Configuration.EventListeners.SaveEventListeners = new ISaveOrUpdateEventListener[] { mylistener }; Configuration.EventListeners.SaveOrUpdateEventListeners = new ISaveOrUpdateEventListener[] { mylistener }; When I save the area, Mylistener is fired 11 times: once for the area, and twice for each SubArea! (I think because NHIbernate is INSERTing the SubArea and then UPDATING with the area foreign key). Does anyone know what I'm doing wrong here, and how I can get the listener to fire once for each area and subarea?

• Search in Stack

  - by WPS

  Hi, I've a Java Stack created and some custom objects added to it. These objects contains unique id as one of their field. I need to get the index of that object in stack based on the unique name. Please find the example. class TestVO{ private String name; private String uniqueId; //getters and setters } public class TestStack{ public static void main(String args[]){ TestVO vo1=new TestVO(); TestVO vo2=new TestVO(); TestVO vo3=new TestVO(); vo1.setName("Test Name 1") vo1.setId("123") vo2.setName("Test name 2"); vo2.setId("234"); Stack<TestVO> stack=new Stack<TestVO>(); stack.add(vo1); stack.add(vo2); //I need to get the index of a VO from stack using it's unique ID } } Can someone please help me to implement this?

• Capture keystrokes (e.g., function keys) while a messagebox is up

  - by FastAl

  We have a large WinForms app, and there is a built-in bug reporting system that can be activated during testing via the F5 Key. I am capturing the F5 key with .Net's PreFilterMessage system. This works fine on the main forms, modal dialog boxes, etc. Unfortunately, the program also displays windows messageboxes when it needs to. When there is a bug with that, e.g., wrong text in the messagebox or it shouldn't be there, the messagefilter isn't executed at all when the messagebox is up! I realize I could fix it by either rewriting my own messagebox routine, or kicking off a separate thread that polls GetAsyncKeyState and calls the error reporter from there. However I was hoping for a method that was less of a hack. Here's code that manifests the problem: Public Class Form1 Implements IMessageFilter Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click MsgBox("now, a messagebox is up!") End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Application.AddMessageFilter(Me) End Sub Public Function PreFilterMessage(ByRef m As System.Windows.Forms.Message) _ As Boolean Implements IMessageFilter.PreFilterMessage Const VK_F5 As Int32 = &H74 Const WM_KEYDOWN As Integer = &H100 If m.Msg = WM_KEYDOWN And m.WParam.ToInt32 = VK_F5 Then ' In reality code here takes a screenshot, saves the program state, and shows a bug report interface ' IO.File.AppendAllText("c:\bugs.txt", InputBox("Describe the bug:")) End If End Function End Class Many thanks.

• Silverlight 3 - How to "refresh" a DataGrid content?

  - by Josimari Martarelli

  I have the following scenery: 1 using System; 2 using System.Windows; 3 using System.Windows.Controls; 4 using System.Windows.Documents; 5 using System.Windows.Ink; 6 using System.Windows.Input; 7 using System.Windows.Media; 8 using System.Windows.Media.Animation; 9 using System.Windows.Shapes; 10 using System.Collections.Generic; 11 12 namespace refresh 13 { 14 public partial class MainPage : UserControl 15 { 16 17 List c = new List(); 18 19 public MainPage() 20 { 21 // Required to initialize variables 22 InitializeComponent(); 23 c.Add(new Customer{ _nome = "Josimari", _idade = "29"}); 24 c.Add(new Customer{_nome = "Wesley", _idade = "26"}); 25 c.Add(new Customer{_nome = "Renato",_idade = "31"}); 26 27 this.dtGrid.ItemsSource = c; 28 } 29 30 private void Button_Click(object sender, System.Windows.RoutedEventArgs e) 31 { 32 c.Add(new Customer{_nome = "Maiara",_idade = "18"}); 33 } 34 35 } 36 37 public class Customer 38 { 39 public string _nome{get; set;} 40 public string _idade{get; set;} 41 } 42 } Where, dtGrid is my DataGrid control... The Question is: How to get the UI Updated after adding one more register to my list. I get to solve it setting the DataGrid's Item Source to "" and then setting to the list of Customer objects again, like that: 1 private void Button_Click(object sender, System.Windows.RoutedEventArgs e) 2 3 { 4 5 c.Add(new Customer{_nome = "Maiara",_idade = "18"}); 6 7 this.dtGrid.ItemsSource=""; 8 9 this.dtGrid.ItemsSource=c; 10 11 } 12 Is there a way to get the UI updated or the datagrid's itemsSource refreshed automatically after updating, altering or deleting an item from the list c ? Thank you, Josimari Martarelli

• WCF for a shared data access

  - by Audrius

  Hi all, I have a little experience with WCF and would like to get your opinion/suggestion on how the following problem can be solved: A web service needs to be accessible from multiple clients simultaneously and service needs to return a result from a shared data set. The concrete project I'm working on has to store a list of IP addresses/ranges. This list will be queried by a bunch of web servers for a validation purposes and we speak of a couple of thousand or more queries per minute. My initial draft approach was to use Windows service as a WCF host with service contract implementing class that is decorated with ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple) that has a list object and a custom locking for accessing it. So basically I have a WCF service singleton with a list = shared data - multiple clients. What I do not like about it is that data and communication layers are merged into one and performance wise this doesn't feel "right". What I really really (- want is Windows service running an instance of IP list holding container class object, a second service running WCF service contract implementation and a way the latter querying the former in a nice way with a minimal blocking. Using another WCF channel would not really take me far away from the initial draft implementation or would it? What approach would you take? Project is still in a very early stage so complete design re-do is not out of question. All ideas are appreciated. Thanks! UPDATE: The data set will be changed dynamically. Web service will have a separate method to add IP or IP range and on top of that there will be a scheduled task that will trigger data cleanup every 10-15 minutes according to some rules. UPDATE 2: a separate benchmark project will be kicked up that should use MSSQL as a data backend (instead on in-memory list).

• Wordpress dynamic navigation function for highlighting single post tabs

  - by user269959

  I am trying to write a function that i can reuse in my wordpress themes that will allow me to build robust dynamic navigation menus. Here is what i have so far: function tab_maker($page_name, $href, $tabname) { //opens <li> tag to allow active class to be inserted if tab is on proper page echo "<li"; //checks that we are on current page and highlights tab as active if so if(is_page($page_name)){ echo " class='current_page_item'>"; } //closes <li> tab if not active else { echo ">"; } //inserts the link as $href and the name of the tab to appear as $tabname then closes <li> echo "<a href=$href>$tabname</a>"; echo "</li>"; } This code works as expected except i cant enable it to highlight for a single blog post as the page names are dynamic. I know about the wordpress function is_single() which ive used to implement this feature in previous nav menus but i cant find a way to integrate it into this function. appreciate any help!

• If statement with code on same block in haml, RoR

  Hello, i have this Haml view: !!! strict %html{:xmlns => "http://www.w3.org/1999/xhtml"} %head %meta{:content => "text/html; charset=utf-8", "http-equiv" => "Content-Type"} %title Lighty | #{@page_title || "Home"} %body #popup Login here #fade #wrapper #container #header %a#logo{:href => "/"} #menu %ul#main %li#lighty %a{:href => "/"} Lighty %ul %li %a Link here %li#community %a{:href => "/community"} Community #content And i would like to add an if on line #16 to check if it is the currently visited page and add the class "active" to the li if it returns true. How do i write that if statement there and is there any easier way to do this? My plan now is to use a variable like @current_page and testif it @current_page == "community" and add a class if it returns right. Am i thinking wrong? any easier way to accomplish this? Thanks for your answer and sorry for my bad english.

• What causes exception in string.concat

  - by Budda

  Here are few classes: public class MyItem : ParamOut { public string Code { get { return _quoteCode; } } public InnerItem[] Skus { get { return _skus; } } public PriceSummary Price { get { return _price; } } public override string ToString() { return string.Concat("Code=", Code, "; SKUs=[", Skus != null ? "{" + string.Join("},{", Array.ConvertAll(Skus, item => item.ToString())) + "}" : "", "]" , "; Price={", Price.ToString(), "}", base.ToString() ); } ... } public abstract class ParamOut { public override string ToString() { return null; } public string ErrorMessage { get; set; } } Here is calling functionality: { MyItem item = new MyItem{ ErrorMessage = "Bla-bla-bla" }; string text = item.ToString(); } I am getting NullReference exception inside of 'ToString()' method (each property of item variable is null). Question: Q1. what overload of string.Concat will be called in this case? I have 9 parameters, so I guess one of the following: public static string Concat(params Object[] args) or public static string Concat(params string[] values) But which of them? Q2. Why exception is generated? Shouldn't 'null' be converted into something like 'null' or "" (empty string)? Thanks a lot!

• How can I inject an object into an WCF IErrorHandler implementation with Castle Windsor?

  - by Michael Johnson

  I'm developing a set of services using WCF. The application is doing dependency injection with Castle Windsor. I've added an IErrorHandler implementation that is added to services via an attribute. Everything is working thus far. The IErrorHandler object (of a class called FaultHandler is being applied properly and invoked. Now I'm adding logging. Castle Windsor is set up to inject the logger object (an instance of IOurLogger). This is working. But when I try to add it to FaultHandler my logger is null. The code for FaultHandler looks something like this: class FaultHandler : IErrorHandler { public IOurLogger logger { get; set; } public bool HandleError(Exception error) { logger.Write("Exception type {0}. Message: {1}", error.GetType(), error.Message); // Let WCF handle things its way. We only want to log. return false; } public void ProvideFault(Exception error, MessageVersion version, Message fault) { } } This throws it's own exception, since logger is null when HandleError() is called. The logger is being successfully injected into the service itself and is usable there, but for some reason I can't use it in FaultHandler. Update: Here is the relevant part of the Windsor configuration file (edited to protect the innocent): <configuration> <components> <component id="Logger" service="Our.Namespace.IOurLogger, Our.Namespace" type="Our.Namespace.OurLogger, Our.Namespace" /> </components> </configuration>

• How to pass SAFEARRAY of UDTs to unmaged code from C#.

I also able to cast elements of obtained SAFEARRAY at unmanaged side to GUID type. But If i tried to pass my UDT class MY_CLASS to unmanaged code with SAFEARRAY then it fails on managed code. (as above code snippet) It shows exception "An unhandled exception of type 'System.Runtime.InteropServices.SafeArrayTypeMismatchException' occurred in myapp.exe" "Additional information: Specified array was not of the expected type." Plz help me in such a situation to pass SAFEARRAY of UDTs to unmaged code.

• Marshal.StringToCoTaskMemAnsi converting non-Latin characters when sending raw data to a printer

  - by rem

  For sending raw data to a thermal DATAMAX printer I'm using RawPrinterHelper class from this Microsoft KB article. When a string sent to printer contains only Latin characters, everything is OK. But non-Latin, in my case Russian characters in a string, are not printed correct. I think the problem is in using Marshal.StringToCoTaskMemAnsi method for converting the string: public static bool SendStringToPrinter(string szPrinterName, string szString) { IntPtr pBytes; Int32 dwCount; // How many characters are in the string? dwCount = szString.Length; // Assume that the printer is expecting ANSI text, and then convert // the string to ANSI text. pBytes = Marshal.StringToCoTaskMemAnsi(szString); // Send the converted ANSI string to the printer. SendBytesToPrinter(szPrinterName, pBytes, dwCount); Marshal.FreeCoTaskMem(pBytes); return true; } Just to note, Russian characters in the string are put in hex format, like "\x83", but nevertheless the method doesn't put this hex value in unmanaged memory as it is, but converts it, I think, according with ANSI code page to a character and then printer can not read it correctly. If I try to compose a file, using Hex editor and put correct hex values in place of non-Latin characters and then send the file to a printer using another method from the same class SendFileToPrinter, everything, including Russian characters is printed correctly. How in this case the problem with sending string, containing non-Latin characters, could be solved?

• System.Threading.Timer keep reference to it.

  - by Daniel Bryars

  According to [http://msdn.microsoft.com/en-us/library/system.threading.timer.aspx][1] you need to keep a reference to a System.Threading.Timer to prevent it from being disposed. I've got a method like this: private void Delay(Action action, Int32 ms) { if (ms <= 0) { action(); } System.Threading.Timer timer = new System.Threading.Timer( (o) => action(), null, ms, System.Threading.Timeout.Infinite); } Which I don't think keeps a reference to the timer, I've not seen any problems so far, but that's probably because the delay periods used have been pretty small. Is the code above wrong? And if it is, how to I keep a reference to the Timer? I'm thinking something like this might work: class timerstate { internal volatile System.Threading.Timer Timer; }; private void Delay2(Action action, Int32 ms) { if (ms <= 0) { action(); } timerstate state = new timerstate(); lock (state) { state.Timer = new System.Threading.Timer( (o) => { lock (o) { action(); ((timerstate)o).Timer.Dispose(); } }, state, ms, System.Threading.Timeout.Infinite); } The locking business is so I can get the timer into the timerstate class before the delegate gets invoked. It all looks a little clunky to me. Perhaps I should regard the chance of the timer firing before it's finished constructing and assigned to the property in the timerstace instance as negligible and leave the locking out.

I created a folder /useradmin/ in my project directory and similar to contrib/admin/_init_.py I added an autodiscover() which will register models defined in useradmin.py modules instead of admin.py: # useradmin/__init__.py def autodiscover(): # Same as admin.autodiscover() but registers useradmin.py modules ... for app in settings.INSTALLED_APPS: mod = import_module(app) try: before_import_registry = copy.copy(site._registry) import_module('%s.useradmin' % app) except: site._registry = before_import_registry if module_has_submodule(mod, 'useradmin'): raise I also cretated sites.py under useradmin/ to override AdminSite similar to contrib/admin/sites: # useradmin/sites.py class UserAdminSite(AdminSite): def has_permission(self, request): # Don't care if the user is staff return request.user.is_active def login(self, request): # Do the login stuff but don't care if the user is staff if request.user.is_authenticated(): ... else: ... site = UserAdminSite(name='useradmin') In the project's URLs: # urls.py from django.contrib import admin import useradmin admin.autodiscover() useradmin.autodiscover() urlpatterns = patterns('', (r'^admin/', include(admin.site.urls)), (r'^useradmin/', include(useradmin.site.urls)), ) And I try to register different models in admin.py and useradmin.py modules under app directories: # products/useradmin.py import useradmin class ProductAdmin(useradmin.ModelAdmin): pass useradmin.site.register(Product, ProductAdmin) But when registering models in useradmin.py like useradmin.site.register(Product, ProductAdmin), I get 'module' object has no attribute 'ModelAdmin' exception. Though when I try this via shell; import useradmin from useradmin import ModelAdmin does not raise any exception. Any ideas what might be wrong? Edit: I tried going the @Luke way and arranged the code as follows as minimal as possible: (file paths are relative to the project root) # admin.py from django.contrib.admin import autodiscover from django.contrib.admin.sites import AdminSite user_site = AdminSite(name='useradmin') # urls.py (does not even have url patterns; just calls autodiscover()) import admin admin.autodiscover() # products/admin.py import admin from products.models import Product admin.user_site.register(Product) As a result I get an AttributeError: 'module' object has no attribute 'user_site' when admin.user_site.register(Product) in products/admin.py is called. Any ideas? Solution: I don't know if there are better ways but, renaming the admin.py in the project root to useradmin.py and updating the imports accordingly resolved the last case, which was a naming and import conflict.

• Showing right sub-ul of parent ul menu

  - by Micke

  Hello, i have this html menu: <ul id='main'> <li class='active current' id='lighty'> <a href='/'>Lighty</a> <ul> <li class='sub'> <a href='/'>Hem</a> </li> </ul> </li> <li id='community'> <a href='/community'>Community</a> </li> </ul> And this jquery: $("#menu ul > li").mouseenter(function(){ id = $(this).attr("id"); $("#menu #main li").removeClass("active"); $(this).addClass("active"); }).mouseleave(function(){ id = $(this).attr("id"); menu.timers[id] = setTimeout(function(){$("#menu #main li#"+id).removeClass("active");}, 2000); }); What i am trying to acomplish is that when i hover one of the li's in the main ul the child ul of that li should be displayed. and when i move the mouse out of the li or the child ul the menu should be visible for 2 seconds. It works through the main li button but if on the child ul and move out it just disapears, it doesnt wait for two seconds. The waiting two seconds is so you can go in to the menu if you accidentaly move the mouse out of it. Can anybody help me to fix this error? Maybe you have a better solution? Here is also a screenshot on how the menu looks if it helps: screen shot under or click here

• Websphere 7 EntityManagerFactory creation problem

  - by mihaela

  Hello, I'm working on a maven project which uses seam 2.2.0, hibernate 3.5.0-CR-2 as JPA provider, DB2 as database server and Websphere 7 as application server. Now I'm facing de following problem: In my EJBs that are seen also as SEAM components I want to use the EntityManager from EJB container (@PersistenceContext private EntityManager em) not Seam's EntityManager (@In private EntityManager em). But this is the problem, I cannot obtain an EntityManager using @PersistenceContext. On server logs it sais that it cannot create an EntityManagerFactory and gets a ClassCastException: java.lang.ClassCastException: org.hibernate.ejb.HibernatePersistence incompatible with javax.persistence.spi.PersistenceProvider After a lot of debugging and searching on forums I'm assuming that the problem is that Websphere doesn't use the Hibernate JPA provider. Has anyone faced this problem and has a solution? I configured already WAS class loader order for my application to load the classes with the application class loader first and I\ve packed all necessary jars in application ear as written in: WAS InfoCenter: Features for EJB 3.0 development . If necessary I'll post my persistence.xml, components.xml files and stack trace. I've found this problem discussed also here: Websphere EntityManagerFactory creation problem Hibernate 3.3 fail to create entity manager factory in Websphere 7.0. Please help Any hint will be useful. Thanks in advance! Mihaela

• Scope of Connection Object for a Website using Connection Pooling (Local or Instance)

  - by Danny

  For a web application with connection polling enabled, is it better to work with a locally scoped connection object or instance scoped connection object. I know there is probably not a big performance improvement between the two (because of the pooling) but would you say that one follows a better pattern than the other. Thanks ;) public class MyServlet extends HttpServlet { DataSource ds; public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } void SomeWork(String sql) { Connection conn = null; try { conn = ds.getConnection(); // execute some sql ..... } finally { if(conn != null) { conn.close(); // return to pool } } } } Or public class MyServlet extends HttpServlet { DataSource ds; Connection conn;* public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { try { conn = ds.getConnection(); SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } finally { if(conn != null) { conn.close(); // return to pool } } } void SomeWork(String sql) { // execute some sql ..... } }

• What is the best way to route a static controller in Rails?

  - by yuval

  I have a static_controller that is in charge of all the static pages in the site and works as follows in routes.rb: map.connect ':id', :controller => 'static', :action => 'show' I have a static page called about that among other information, has a contact form. I currently have a contacts_controller that is in charge of inserting the contact information to the database. Inside my routes.rb file, I have: map.resources :contacts My contact form (simplified) looks like this: <% form_for @contact do |f| %> <p class="errors"><%= f.error_messages %></p> <p> <%= f.label :first_name %> <%= f.text_field :first_name %> </p> <p class="buttons"><%= f.submit %></p> <% end %> Which in turn submits to the create action of my contacts_controller. My create action looks like this: def create @contact = Contact.new(params[:contact]) if @contact.save flash[:notice] = "Email delivered successfully." end redirect_to "about" end The problem is, is the that when I redirect back to my about page the error_messages for the form get lost (since the error_messages for the form only exist for one request, and that request ends upon redirect). How would I go about preserving the error_messages and still linking the users back to the about static url? Would a session/flash be sufficient (if so, what code would I use to pass error messages) or am I going about this whole thing wrong? Thanks!

• undefined method `build_users' with nested models

  - by Cédric

  I've got into trouble with nested attributes. Here is my Account model : class Account < ActiveRecord::Base has_many :products has_many :blogs has_many :openings has_many :users has_one :logo, :class_name => "AccountPicture" has_one :address, :class_name => "AccountAddress" has_and_belongs_to_many :options accepts_nested_attributes_for :logo, :allow_destroy => true accepts_nested_attributes_for :address, :allow_destroy => true accepts_nested_attributes_for :users, :allow_destroy => true end And here is my User model : class User < ActiveRecord::Base belongs_to :account end As you can see, Account accepts nested attributes for logo, address, and users. While testing, i can use nested attributes for logo and address, but not for user. a = Account.new => #<Account id: nil, hostname: nil, subdomain: nil, name: nil, description: nil, base_line: nil, footer: nil, phone_number: nil, mobile_number: nil, email_address: nil, created_at: nil, updated_at: nil> # building the address works fine >> a.build_address => #<AccountAddress id: nil, account_id: nil, country: nil, state: nil, county: nil, city: nil, suburb: nil, zipcode: nil, street: nil, streetno: nil, longitude: nil, latitude: nil, error_code: nil> # building the users fails >> a.build_users NoMethodError: undefined method `build_users' for #<Account:0x7f6862a5f948> from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/attribute_methods.rb:260:in `method_missing' from (irb):2 Thus, in my views, when i use the nested forms, i got this error back : User(#69850615730460) expected, got Array(#69850664775200) Any help would be appreciated. Thanks.
