  • CIL and JVM Little endian to big endian in c# and java

    - by Haythem
    Hello, I am using on the client C# where I am converting double values to byte array. I am using java on the server and I am using writeDouble and readDouble to convert double values to byte arrays. The problem is the double values from java at the end are not the double values at the begin giving to c# writeDouble in Java Converts the double argument to a long using the doubleToLongBits method , and then writes that long value to the underlying output stream as an 8-byte quantity, high byte first. DoubleToLongBits Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "double format" bit layout. The Program on the server is waiting of 64-102-112-0-0-0-0-0 from C# to convert it to 1700.0 but he si becoming 0000014415464 from c# after c# converted 1700.0 this is my code in c#: class User { double workingStatus; public void persist() { byte[] dataByte; using (MemoryStream ms = new MemoryStream()) { using (BinaryWriter bw = new BinaryWriter(ms)) { bw.Write(workingStatus); bw.Flush(); bw.Close(); } dataByte = ms.ToArray(); for (int j = 0; j < dataByte.Length; j++) { Console.Write(dataByte[j]); } } public double WorkingStatus { get { return workingStatus; } set { workingStatus = value; } } } class Test { static void Main() { User user = new User(); user.WorkingStatus = 1700.0; user.persist(); } thank you for the help.

  • Rails: Multiple "has_many through" for the two same models?

    - by neezer
    Can't wrap my head around this... class User < ActiveRecord::Base has_many :fantasies, :through => :fantasizings has_many :fantasizings, :dependent => :destroy end class Fantasy < ActiveRecord::Base has_many :users, :through => :fantasizings has_many :fantasizings, :dependent => :destroy end class Fantasizing < ActiveRecord::Base belongs_to :user belongs_to :fantasy end ... which works fine for my primary relationship, in that a User can have many Fantasies, and that a Fantasy can belong to many Users. However, I need to add another relationship for liking (as in, a User "likes" a Fantasy rather than "has" it... think of Facebook and how you can "like" a wall-post, even though it doesn't "belong" to you... in fact, the Facebook example is almost exactly what I'm aiming for). I gathered that I should make another association, but I'm kinda confused as to how I might use it, or if this is even the right approach. I started by adding the following: class Fantasy < ActiveRecord::Base ... has_many :users, :through => :approvals has_many :approvals, :dependent => :destroy end class User < ActiveRecord::Base ... has_many :fantasies, :through => :approvals has_many :approvals, :dependent => :destroy end class Approval < ActiveRecord::Base belongs_to :user belongs_to :fantasy end ... but how do I create the association through Approval rather than through Fantasizing? If someone could set me straight on this, I'd be much obliged!

  • Redraw and flicker issues

    - by AngryHacker
    I have an Outlook style app. So basically I have a sidebar on the left and on the right I have a panel control (pnlMainBody) that hosts content. The content is typically a user control that I add to the panel when user clicks appropriate button in the side bar. The way I add the user control to the panel is as follows: // _pnlEmails is the User Control that I am adding to the panel _pnlEmails = new pnlEmails(); _pnlEmails.Dock = DockStyle.Fill; this.pnlMainBody.Controls.Add(_pnlEmails); Some of the user controls that I add to the main panel are quite complex UI-wise. So when this.pnlMainBody.Controls.Add(_pnlEmails); fires, I see the control appear on the screen, then it resizes itself to fill the body of the panel control. It's quite ugly actually, so I was wondering whether there is a way to not show the resizing until it's actually done resizing? I've tried setting the user control's .Visible to false. I've tried doing .SuspendLayout, all to no avail. Is there a way to do this so the screen transitions are smooth?

  • failed to connect to any given host:port - RoR Error?

    - by Sam Hursey
    Hi all I'm very new to Ruby on Rails so please go easy! I've uploaded the whole application to the server (Dreamhost) and gone through the steps. But when I try to run it I get the following error: failed to connect to any given host:port (Mongo::ConnectionFailure) I have installed the Mongo gem; but maybe I haven't got it configured correctly? I know you can't use localhost for describing where a Dreamhost mysql database is; might it be something like that? These are the first five lines of the backtrace if that helps?: /home/user/.gem/ruby/1.8/gems/mongo-0.19.1/lib/../lib/mongo/connection.rb 440 in `connect_to_master' 1 /home/user/.gem/ruby/1.8/gems/mongo-0.19.1/lib/../lib/mongo/connection.rb 131 in `initialize' 2 /home/user/.gem/ruby/1.8/gems/magent-0.3/lib/magent.rb 19 in `new' 3 /home/user/.gem/ruby/1.8/gems/magent-0.3/lib/magent.rb 19 in `connection' 4 /home/user/.gem/ruby/1.8/gems/magent-0.3/lib/magent.rb 27 in `database=' 5 /home/user/.gem/ruby/1.8/gems/magent-0.3/lib/magent.rb 35 Any help much appreciated and apologies for my n00bishness!

  • Generics with constraints hierarchy

    - by devoured elysium
    I am currently facing a very disturbing problem: interface IStateSpace<Position, Value> where Position : IPosition // <-- Problem starts here where Value : IValue // <-- and here as I don't { // know how to get away this // circular dependency! // Notice how I should be // defining generics parameters // here but I can't! Value GetStateAt(Position position); void SetStateAt(Position position, State state); } As you'll down here, both IPosition, IValue and IState depend on each other. How am I supposed to get away with this? I can't think of any other design that will circumvent this circular dependency and still describes exactly what I want to do! interface IState<StateSpace, Value> where StateSpace : IStateSpace where Value : IValue { StateSpace StateSpace { get; }; Value Value { get; set; } } interface IPosition { } interface IValue<State> where State : IState { State State { get; } } Basically I have a state space IStateSpace that has states IState inside. Their position in the state space is given by an IPosition. Each state then has one (or more) values IValue. I am simplifying the hierarchy, as it's a bit more complex than described. The idea of having this hierarchy defined with generics is to allow for different implementations of the same concepts (an IStateSpace will be implemented both as a matrix as an graph, etc). Would can I get away with this? How do you generally solve this kind of problems? Which kind of designs are used in these cases? Thanks

  • Python Twitter library: which one?

    - by Parand
    I realize this is a bit of a lazyweb question, but I wanted to see which python library for Twitter people have had good experiences with. I've used Python Twitter Tools and like its brevity and beauty of interface, but it doesn't seem to be one of the popular ones - it's not even listed on the Twitter Libraries page. There are, however, plenty of others listed: oauth-python-twitter2 by Konpaku Kogasa. Combines python-twitter and oauth-python-twitter to create an evolved OAuth Pokemon. python-twitter by DeWitt Clinton. This library provides a pure Python interface for the Twitter API. python-twyt by Andrew Price. BSD licensed Twitter API interface library and command line client. twitty-twister by Dustin Sallings. A Twisted interface to Twitter. twython by Ryan McGrath. REST and Search library inspired by python-twitter. Tweepy by Josh Roesslein. Supports OAuth, Search API, Streaming API. My requirements are fairly simple: Be able to use OAuth Be able to follow a user Be able to send a direct message Be able to post Streaming API would be nice Twisted one aside (I'm not using twisted in this case), have you used any of the others, and if so, do you recommend them? [Update] FWIW, I ended up going with Python Twitter Tools again. The new version supported OAuth nicely, and it's a very clever API, so I stuck to it.

  • Django's self.client.login(...) does not work in unit tests

    - by thebossman
    I have created users for my unit tests in two ways: 1) Create a fixture for "auth.user" that looks roughly like this: { "pk": 1, "model": "auth.user", "fields": { "username": "homer", "is_active": 1, "password": "sha1$72cd3$4935449e2cd7efb8b3723fb9958fe3bb100a30f2", ... } } I've left out the seemingly unimportant parts. 2) Use 'create_user' in the setUp function (although I'd rather keep everything in my fixtures class): def setUp(self): User.objects.create_user('homer', '[email protected]', 'simpson') Note that the password is simpson in both cases. I've verified that this info is correctly being loaded into the test database time and time again. I can grab the User object using User.objects.get. I can verify the password is correct using 'check_password.' The user is active. Yet, invariably, self.client.login(username='homer', password='simpson') FAILS. I'm baffled as to why. I think I've read every single Internet discussion pertaining to this. Can anybody help? The login code in my unit test looks like this: login = self.client.login(username='homer', password='simpson') self.assertTrue(login) Thanks.

  • Wrapping FUSE from Go

    - by Matt Joiner
    I'm playing around with wrapping FUSE with Go. However I've come stuck with how to deal with struct fuse_operations. I can't seem to expose the operations struct by declaring type Operations C.struct_fuse_operations as the members are lower case, and my pure-Go sources would have to use C-hackery to set the members anyway. My first error in this case is "can't set getattr" in what looks to be the Go equivalent of a default copy constructor. My next attempt is to expose an interface that expects GetAttr, ReadLink etc, and then generate C.struct_fuse_operations and bind the function pointers to closures that call the given interface. This is what I've got (explanation continues after code): package fuse // #include <fuse.h> // #include <stdlib.h> import "C" import ( //"fmt" "os" "unsafe" ) type Operations interface { GetAttr(string, *os.FileInfo) int } func Main(args []string, ops Operations) int { argv := make([]*C.char, len(args) + 1) for i, s := range args { p := C.CString(s) defer C.free(unsafe.Pointer(p)) argv[i] = p } cop := new(C.struct_fuse_operations) cop.getattr = func(*C.char, *C.struct_stat) int {} argc := C.int(len(args)) return int(C.fuse_main_real(argc, &argv[0], cop, C.size_t(unsafe.Sizeof(cop)), nil)) } package main import ( "fmt" "fuse" "os" ) type CpfsOps struct { a int } func (me *CpfsOps) GetAttr(string, *os.FileInfo) int { return -1; } func main() { fmt.Println(os.Args) ops := &CpfsOps{} fmt.Println("fuse main returned", fuse.Main(os.Args, ops)) } This gives the following error: fuse.go:21[fuse.cgo1.go:23]: cannot use func literal (type func(*_Ctype_char, *_Ctype_struct_stat) int) as type *[0]uint8 in assignment I'm not sure what to pass to these members of C.struct_fuse_operations, and I've seen mention in a few places it's not possible to call from C back into Go code. If it is possible, what should I do? How can I provide the "default" values for interface functions that acts as though the corresponding C.struct_fuse_operations member is set to NULL?

  • Multiple dynamic timers

    - by Rickard
    I am working on a project where I need to let the user create one (or more) timers to fire off an event. The user is supposed to define variables such as if the timer should be active and how often the timer will fire along with some other variables of what will happen when the timer is fiering. All these variables are stored in a dictionary (Disctionary) where the object holds all the variables the user has set and the string is the name that the user has chosen for this timer. I then want my program to loop through this dictionary and search for all objects which has the variable t_Active set to true (this I have already achieved). What I need help with figuring out is the follwoing: When it detects the variable, and if it's set to true, I need the program to see if there is already a timer created for this. If it isn't, it should create one and set the relevant parameters for the timer. The two variables t_num and t_period should decide the interval of the timer. t_num is an int and t_period is a string which will be set to either minutes, hours or days. Combining t_num with 60000 (minutes), 3600000 (hours) or 86400000 should give the corrct interval. But how would I go on about programatically create a timer for each user-defined active object? And how do I get the program to detect wether or not a timer has already been created? I have been searching both here and on google, but so far I haven't come across something that makes sense to me. I am still learning C#, so what make sense to you guys may not neccessarilly make sense to me yet. :) I hope I have explaned what I need good enough, please do ask me to clarify if you don't get me. Edit: Maybe I should also mention that the mentioned dictionary will also be saved to an XML file to that the user can pick up all the settings they made at any time.

  • Silverlight 4 seems like starving of memory

    - by Marco
    I have been playing a bit with Silverlight and try to port my Silverlight 3.0 application to Silverlight 4.0. My application loads different XAP files and upon a user request create an instance of a Xaml user control and adds it to the main container, in a sort of MEF approach in order I can have an extensible and pluggable application. The application is pretty huge and to keep acceptable the performances and the initial loading I have built up some helper classes to load in the background all pages and user controls that might be used later on. On Silverlight 3.0 everything was running smoothly without any problem so far. Switching to SL 4.0 I have noticed that when the process approaches to create the instances of the user controls the layout freezes unexpectedly for a minute and sometimes for more. Looking at the task manager the memory usage of IE jumps from 50MB to 400MB and sometimes up to 1.5 GB. If the process won't take that much the layout is rendered properly even though the memory usage is still extremely high. Otherwise everything crashes due to out of memory exception. Running the same application compiled in SL3, the memory used is about 200MB when all the usercontrols are loaded. Time spent to load the application in SL3 is about 10 seconds, while it takes up to 3 mins in SL4 There are no transparencies, no opacities set, no effects and animations in the layout. User controls are instantied on the fly and added or removed in the visual tree on purpose when the user switches from one screen to another. The resources are all cleaned properly when a usercontrol is removed from the visual tree to allow the GC to operate in the background. I may do something wrong but I could not figure out where exactly nail out the source of this problem. As far as I know there is no memory profiler in SL4 that can help me out to find where to look at. But again I could not be updated on new debugging tools available.

  • how to atomically claim a row or resource using UPDATE in mysql

    - by Igor
    i have a table of resources (lets say cars) which i want to claim atomically. if there's a limit of one resource per one user, i can do the following trick: UPDATE cars SET user = 'bob' WHERE user IS NULL LIMIT 1 SELECT * FROM cars WHERE user IS bob that way, i claim the resource atomically and then i can see which row i just claimed. this doesn't work when 'bob' can claim multiple cars. i realize i can get a list of cars already claimed by bob, claim another one, and then SELECT again to see what's changed, but that feels hackish. What I'm wondering is, is there some way to see which rows i just updated with my last UPDATE? failing that, is there some other trick to atomically claiming a row? i really want to avoid using SERIALIZABLE isolation level. If I do something like this: 1 SELECT id FROM cars WHERE user IS NULL 2 <here, my PHP or whatever picks a car id> 3 UPDATE cars SET user = 'bob' WHERE id = <the one i picked> would REPEATABLE READ be sufficient here? in other words, could i be guaranteed that some other transactions won't claim the row my software has picked during step 2?

  • Rails - Logic for finding info from a :has_many :through needed!

    - by Jty.tan
    I have 3 relevant tables. User, Orders, and Viewables The idea is that each User has got many Orders, but at the same time, each User can View specific other Orders that belong to other Users. So Viewables has the attributes of user_id and order_id. Orders has a :has_many :Users, :through => :viewables Is it possible to do a find through an Order's view? So something like @viewable_orders = Orders.find(:all, :conditions = ["Viewable.user_id=?",1]) To get a list of Orders which are viewable by user_id=1. (This doesn't work, else I won't be asking. :( ) The idea being that I can do something like a sidebar where the current user (the logged-in one) can view a list of other people's orders that he can view. For example Three other Users who have some Orders that he can view should be eventually displayed like this: Jack (2) Basic Order (registry_id: 1) New Order (registry_id: 29) Amy (4) Short Order (registry_id: 12) Jill (5) Hardware Order (14) Pink Order (17) Software Order (76) (The number in brackets are the respective user_id or registry_id) So to find the list of all of the orders that the current user can find (assuming user_id of the current user is 1), would be found by doing @viewable_orders = Viewable.find(:all, :conditions => ["user_id=?", 1]) And that would give me the collection of the above 6 registries. Now, the easiest way to do this, is for me to just have a list of + Jill's Hardware Order + Jill's Pink Order + Amy's Short Order + etc But that gets ugly for long lists. Thanks!

  • How do I implement repository pattern and unit of work when dealing with multiple data stores?

    - by Jason
    I have a unique situation where I am building a DDD based system that needs to access both Active Directory and a SQL database as persistence. Initially this wasnt a problem because our design was setup where we had a unit of work that looked like this: public interface IUnitOfWork { void BeginTransaction() void Commit() } and our repositories looked like this: public interface IRepository<T> { T GetByID() void Save(T entity) void Delete(T entity) } In this setup our load and save would handle the mapping between both data stores because we wrote it ourselves. The unit of work would handle transactions and would contain the Linq To SQL data context that the repositories would use for persistence. The active directory part was handled by a domain service implemented in infrastructure and consumed by the repositories in each Save() method. Save() was responsible with interacting with the data context to do all the database operations. Now we are trying to adapt it to entity framework and take advantage of POCO. Ideally we would not need the Save() method because the domain objects are being tracked by the object context and we would just need to add a Save() method on the unit of work to have the object context save the changes, and a way to register new objects with the context. The new proposed design looks more like this: public interface IUnitOfWork { void BeginTransaction() void Save() void Commit() } public interface IRepository<T> { T GetByID() void Add(T entity) void Delete(T entity) } This solves the data access problem with entity framework, but does not solve the problem with our active directory integration. Before, it was in the Save() method on the repository, but now it has no home. The unit of work knows nothing other than the entity framework data context. Where should this logic go? I argue this design only works if you only have one data store using entity framework. Any ideas how to best approach this issue? Where should I put this logic?

  • Reflection: cast an object to subclass without use instaceof

    - by Fabrizio
    I have this simple interface/class: public abstract class Message { } public class Message1 extends Message{ } public class Message2 extends Message{ } And an utility class: public class Utility { public void handler(Message m){ System.out.println("Interface: Message"); } public void handler(Message1 m){ System.out.println("Class: Message1"); } public void handler(Message2 m){ System.out.println("Class: Message2"); } } Now, the main class: public static void main(String[] args) { Utility p=new Utility(); Message1 m1=new Message1(); p.handler(m1); Message m=(Message) m1; p.handler(m); } The output is Class: Message1 Interface: Message I would that p.handler(m) call the method p.handler(m:Message1) I don't want use the "manual" command instanceof because I have many cases: if(m instance of Message1) p.handler((Message1)m) else if (m instanceof Message2) p.handler((Message2)m) ... If I call m.getClass() I obtain "mypackage.Message1", so the subclass and not the superclass. I try with this code (use reflection): p.handler(m.getClass().cast(m)); But the output is Interface: Message So, this is my problem. I would do a runtime cast of superclass object to subclassobject without use the "code command" istanceof. I would a right command like this: p.handler((m.getclass)m); How can I obtain it? It's possible? Thank in advance. Fabrizio

  • C# ErrorProvider Want to know if any are Active

    - by RcK
    I want to know if any ErrorProvider are active in my form. being able to find this out might help reduce my code.. I did find this thing here Counting ErrorProvider but incase someone knows a better way... so here goes. Ok so basically I have a WinForm which has many TextBoxes Now when user enters values I use Validating to perform validation and if it does not match Regex I set the ErrorProvider ON for that Control.. similarly if the user changes the value to a acceptable one I switch ErrorProvider OFF for that Control.. but when SAVE is clicked i have to do another check anyways incase the user did not listen to me and change the thing like he was supposed to and still clicked SAVE.. I dont want the thing crashing.. soo mm is there like a thing where I could say if ErrorProviders is not active then proceed with save else message box saying change it. [ANOTHER QUESTION] Umm When Validating it only Validates when the Control loses Focus... I kinda of want it to do validation when user stops typing.. I hope you get what I mean Like Email Address(textbox) when user is typing his/her name in I [DON'T] want it to do validation yet, but when user has finished entering is waiting for ErrorProvider to disappear(But it doesn't coz it only does that when control loses focus) 2 odd seconds after typing can i make the validation take place?

  • Delphi Mock Wizard

    - by Todd
    Let me preface this by saying I'm fairly new to Unit Testing, Mocks, Stubs, Etc... I've installed Delphi-Mock-Wizard. When I select a unit and "Generate Mock", a new unit is created but it's very basic and not anything what I understand Mocks to be. unit Unit1; (** WARNING - AUTO-GENERATED MOCK! Change this unit if you want to, but be aware that any changes you make will be lost if you regenerate the mock object (for instance, if the interface changes). My advice is to create a descendent class of your auto-generated mock - in a different unit - and override things there. That way you get to keep them. Also, the auto-generate code is not yet smart enough to generate stubs for inherited interfaces. In that case, change your mock declaration to inherit from a mock implementation that implements the missing interface. This, unfortunately, is a violation of the directive above. I'm working on it. You may also need to manually change the unit name, above. Another thing I am working on. **) interface uses PascalMock, TestInterfaces; type IThingy = interface; implementation end. Looking at the source there seems to be quite a bit commented out. I'm wondering, has anyone gotten this to work? My IDE is D2010. Thanks.

  • @Autowire strange problem

    - by Javi
    Hello, I have a strange behaviour when autowiring I have a similar code like this one, and it works @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2{ ... } The problem is that I need that the Class2 implements an interface so I've only changed the Class2 so it's now like: @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2 implements IServiceReference<Class3, Long>{ ... } public interface IServiceReference<T, PK extends Serializable> { public T reference(PK id); } with this code I get a org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type for Class2. It seems that @ Transitional annotation is not compatible with the interface because if I remove the @Transitional annotation or the "implements IServiceReference" the problem disapears and the bean is injected (though I need to have both in this class). It also happens if I put the annotation @Transitional in the methods instead of in the Class. I use Spring 3.0.2 if this helps. Is not compatible the interface with the transactional method? May it be a Spring bug? Thanks

  • How will Arel affect rails' includes() 's capabilities.

    - by Tim Snowhite
    I've looked over the Arel sources, and some of the activerecord sources for Rails 3.0, but I can't seem to glean a good answer for myself as to whether Arel will be changing our ability to use includes(), when constructing queries, for the better. There are instances when one might want to modify the conditions on an activerecord :include query in 2.3.5 and before, for the association records which would be returned. But as far as I know, this is not programmatically tenable for all :include queries: (I know some AR-find-includes make t#{n}.c#{m} renames for all the attributes, and one could conceivably add conditions to these queries to limit the joined sets' results; but others do n_joins + 1 number of queries over the id sets iteratively, and I'm not sure how one might hack AR to edit these iterated queries.) Will Arel allow us to construct ActiveRecord queries which specify the resulting associated model objects when using includes()? Ex: User :has_many posts( has_many :comments) User.all(:include => :posts) #say I wanted the post objects to have their #comment counts loaded without adding a comment_count column to `posts`. #At the post level, one could do so by: posts_with_counts = Post.all(:select => 'posts.*, count(comments.id) as comment_count', :joins => 'left outer join comments on comments.post_id = posts.id', :group_by => 'posts.id') #i believe #But it seems impossible to do so while linking these post objects to each #user as well, without running User.all() and then zippering the objects into #some other collection (ugly) #OR running posts.group_by(&:user) (even uglier, with the n user queries)

  • how to match var/id to class

    - by circey
    Hi. I'm new to jquery and, in addition, I think I'm having a brain freeze. I have a number of links with different ids. I want to match the clicked link with a div with the corresponding class so the div will show/hide/toggle as appropriate. I have: <script type="text/javascript"> $(document).ready(function() { $('.folioBox').hide(); $('a.interface').click(function(){ var currentId = $(this).attr('id'); var currentBox = $('.folioBox .' + currentId); $(currentBox).toggle(400); }); }); </script> <a class="interface" id="apple">Apple flavor</a> <a class="interface" id="banana">Banana flavor</a> <a class="interface" id="cherry">Cherry flavor</a> <div class="folioBox apple">content</div> <div class="folioBox banana">content</div> <div class="folioBox cherry">content</div> I just can't get it to work and I can't figure out whether I would be best using match or find or filter. Some assistance would be much appreciated!

  • Problem with persisting a collection, that references an internal property, at design time in winfor

    ETA: Jesus, I'm sick of this. This problem was specifically about persisting an interface collection but now on further testing it doesn't work for a normal collection. Here's some even simpler code: Public Class Anger End Class Public Class MyButton Inherits Button Private _Annoyance As List(Of Anger) <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As List(Of Anger) Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New List(Of Anger) Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class The designer screws up the persistence code in the same way as the original problem. ---- Original Problem The easiest way to explain this problem is to show you some code: Public Interface IAmAnnoyed End Interface Public Class IAmAnnoyedCollection Inherits ObjectModel.Collection(Of IAmAnnoyed) End Class Public Class Anger Implements IAmAnnoyed End Class Public Class MyButton Inherits Button Private _Annoyance As IAmAnnoyedCollection <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As IAmAnnoyedCollection Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New IAmAnnoyedCollection Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class And this is the code that the designer generates: Private Sub InitializeComponent() Dim Anger1 As Anger = New Anger Me.MyButton1 = New MyButton ' 'MyButton1 ' Me.MyButton1.Annoyance.Add(Anger1) // Should be: Me.MyButton1.Annoyance.Add(Me.MyButton1.InternalAnger) ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub I've added a comment to the above to show how the code should have been generated. Now, if I dispense with the interface and just have a collection of Anger, then it persists correctly. Any ideas?

  • understanding the models in MVC

    - by fayer
    i cant fully understand the models in MVC. so i am using symfony with doctrine. the doctrine models are created. does this mean that i don't have to create any models? are the doctrine models the only models i need? where should i put the code that uses the doctrine models: eg. $phoneIds = array(); $phone1 = new Phonenumber(); $phone1['phonenumber'] = '555 202 7890'; $phone1->save(); $phoneIds[] = $phone1['id']; $phone2 = new Phonenumber(); $phone2['phonenumber'] = '555 100 7890'; $phone2->save(); $phoneIds[] = $phone2['id']; $user = new User(); $user['username'] = 'jwage'; $user['password'] = 'changeme'; $user->save(); $user->link('Phonenumbers', $phoneIds); should this code be in the controller or in another model? and where should i validate these fields (check if it exists in database, that email is email etc)? could someone please shed a light on this. thanks.

  • Make browser to go back by reloading page 1st and then scrolling it back again too

    - by Marco Demaio
    EXPLAINING WHAT I'M TRYING TO SOLVE: I have a webpage (file_list.php) showing a list of files, and next to each file there is a button to delete it. When user press the DELETE button close to a certain file name, the browser goes to a script called delete_file.php that deletes the file and then it tells browser to go back to the file_list.php delete_file.php uses a simple header("Location: file_list.php”); to go back to file_list.php When browser goes back to file_list.php it reloads the page, but it DOES NOT scroll it back again to where the user was before. So let's say the user scrolled the files list and deleted the last file, when the browser shows again the page file_list.php it won't be scrolled to the bottom of the page again. THE WORKAROUND I CAME OUT WITH: I found a strange way to work around this, basically instead of using header("Location: file_list.php”); in delete_file.php I simply use a javascript call window.history.go(-1). This workaround works perfectly when user is in session (simply using PHP session_start function): the browser RELOADS the file_list.php page and then scrolls it also bask to where it was before. But if the user is NOT in session the browser scrolls the page but IT DOES NOT RELOAD IT before, so the user would still see the file he deleted in the file list. THE QUESTIONS Do you know how to reproduce the behavior of the browser when goes back being in session even if we are not in session? Do you know a way out of this, even another way of solving this matter? Thanks! *I know I could use AJAX to delete the file so I would not have to go every time to delete_file.php, but this is not the answer*.

  • Some regular expression help?

    - by Rohan
    Hey there. I'm trying to create a Regex javascript split, but I'm totally stuck. Here's my input: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. ***This is a comment 11:30 am This is some more input. I want the output array after the split() to be (I've removed the \n for readability): ["9:30 pm The user did action A.", "10:30 pm Welcome, user John Doe.", "***This is a comment", "11:30 am This is some more input." ]; My current regular expression is: var split = text.split(/\s*(?=(\b\d+:\d+|\*\*\*))/); This works, but there is one problem: the timestamps get repeated in extra elements. So I get: ["9:30", "9:30 pm The user did action A.", "10:30", "10:30 pm Welcome, user John Doe.", "***This is a comment", "11:30", "11:30 am This is some more input." ]; I cant split on the newlines \n because they aren't consistent, and sometimes there may be no newlines at all. Could you help me out with a Regex for this? Thanks so much!!

  • nhibernate not taking mappings from assembly

    - by cvista
    Hi I'm using fnh and castle nhib facility. I followed the advice from mike hadlow here: http://mikehadlow.blogspot.com/2009/01/integrating-fluent-nhibernate-and.html here is my FluentNHibernateConfigurationBuilder: public Configuration GetConfiguration(IConfiguration facilityConfiguration) { var defaultConfigurationBuilder = new DefaultConfigurationBuilder(); var configuration = defaultConfigurationBuilder.GetConfiguration(facilityConfiguration); configuration.AddMappingsFromAssembly(typeof(User).Assembly); return configuration; } i know the facility is picking it up as i can break inside that method and it steps through. however, when it's done, non of the mappings are created and i get the following error when i try to save an entity: No persister for: IsItGd.Model.Entities.User here is my user class: //simple model of web user public class User { public virtual int Id { get; set; } public virtual string FullName { get; set; } } and here is the mapping: public class UserMap : ClassMap<User> { public UserMap() { Id(x=>x.Id); Map(x=>x.FullName); } } i really can't see what the problem is. the strange thing is - is that if i use automapping it picks everything up - but i don't want to use automapping as i can't do certain things in that scenario. any clues? w://
