  • How to get this.grandparent() functionality in Mootools?

    - by RyOnLife
    I have built a class in Mootools and extended it twice, such that there is a grandparent, parent, and child relationship: var SomeClass1 = new Class({ initialize: function() { // Code }, doSomething: function() { // Code } }); var SomeClass2 = new Class({ Extends: SomeClass1, initialize: function() { this.parent(); }, doSomething: function() { this.parent(); // Some code I don't want to run from Class3 } }); var SomeClass3 = new Class({ Extends: SomeClass2, initialize: function() { this.parent(); }, doSomething: function() { this.grandParent(); } }); From Class3, the child, I need call the doSomething() method from Class1, the grandparent, without executing any code in Class2#doSomething(), the parent. What I need is a grandParent() method to complement the Mootools parent(), but it appears that one does not exist. What's the best way to accomplish this in either Mootools or pure JavaScript? Thanks.

  • Stored procedure execution problem

    - by geeta
    Iam implementing entity spaces in C# application and was able to execute queries such as the below one successfully. coll.query.where(coll.prodlineid.equal("id") if( coll.query.load()) However I need to replace all these queries in the code with Stored procedures. For this I used: coll.Load(esQuerytype.storedprocedure, "testproc", param) At this point, Iam getting error as 'EntitySpaces.Core.esEntityCollection.Load(EntitySpaces.DynamicQuery.esQueryType, string, params object[])' is inaccessible due to its protection level esEntityCollection is a metadata file, so I could not change the access modifier there from protected to public. Help:-)

  • Testing Broadcasting and receiving messages

    - by Avik
    Guys am having some difficulty figuring this out: I am trying to test whether the code(in c#) to broadcast a message and receiving the message works: The code to send the datagram(in this case its the hostname) is: public partial class Form1 : Form { String hostName; byte[] hostBuffer = new byte[1024]; public Form1() { InitializeComponent(); StartNotification(); } public void StartNotification() { IPEndPoint notifyIP = new IPEndPoint(IPAddress.Broadcast, 6000); hostName = Dns.GetHostName(); hostBuffer = Encoding.ASCII.GetBytes(hostName); UdpClient newUdpClient = new UdpClient(); newUdpClient.Send(hostBuffer, hostBuffer.Length, notifyIP); } } And the code to receive the datagram is: public partial class Form1 : Form { byte[] receivedNotification = new byte[1024]; String notificationReceived; StringBuilder listBox; UdpClient udpServer; IPEndPoint remoteEndPoint; public Form1() { InitializeComponent(); udpServer = new UdpClient(new IPEndPoint(IPAddress.Any, 1234)); remoteEndPoint=null; startUdpListener1(); } public void startUdpListener1() { receivedNotification = udpServer.Receive(ref remoteEndPoint); notificationReceived = Encoding.ASCII.GetString(receivedNotification); listBox = new StringBuilder(this.listBox1.Text); listBox.AppendLine(notificationReceived); this.listBox1.Items.Add(listBox.ToString()); } } For the reception of the code I have a form that has only a listbox(listBox1). The problem here is that when i execute the code to receive, the program runs but the form isnt visible. However when I comment the function call( startUdpListener1() ), the purpose isnt served but the form is visible. Whats going wrong?

  • How cross-platform .Net framework really is?

    - by Ivan
    What is normally to be done to run a WinForms application on a Mac or Linux machine? a. Just copy and run (assuming they have a Framework installed). b. Rebuild. c. Cosmetic source code modifications. d. Heavy source code modifications and forms redesign. Assuming that the application is developed as 100% managed C# 3 code by means Visual C# Express or Visual Studio 2008 targeting .Net Framework 3.5, developed without using any 3-rd party components/libraries, without encapsulating nonmanaged code or any low-level hacks - only standard Microsoft-documented .Net Framework C# API used). Or the same conditions but C# 4 language, .Net Framework 4 and Visual Studio 2010.

  • Do I have to create a static library to test my application?

    - by Christopher Gateley
    I'm just getting started with TDD and am curious as to what approaches others take to run their tests. For reference, I am using the google testing framework, but I believe the question is applicable to most other testing frameworks and to languages other than C/C++. My general approach so far has been to do either one of three things: Write the majority of the application in a static library, then create two executables. One executable is the application itself, while the other is the test runner with all of the tests. Both link to the static library. Embed the testing code directly into the application itself, and enable or disable the testing code using compiler flags. This is probably the best approach I've used so far, but clutters up the code a bit. Embed the testing code directly into the application itself, and, given certain command-line switches either run the application itself or run the tests embedded in the application. None of these solutions are particularly elegant... How do you do it?

  • Hot deploy on Heroku with no downtime

    - by zetarun
    A bad side of pushing to Heroku is that I must push the code (and the server restarts automatically) before running my db migrations. This can obviously cause some 500 errors on users navigating the website having the new code without the new tables/attributes: the solution proposed by Heroku is to use the maintenance mode, but I want a way with no downside letting my webapp running everytime! Is there a way? For example with Capistrano: I prepare the code to deploy in a new dir I run (backward) migrations and the old code continue to work perfectly I swith mongrel instance to the new dir and restart the server ...and I have no downtime!

  • Is it possible to run locally JRuby on Google App Engine without restarting server on every change?

    - by elado
    Unfortunately, GAE requires restart of the server on each code change. Is it possible to prevent it and have immediate feedback after code save? Or, can I import Google App Engine's API into my ruby code and run it on Sinatra server? Tried this but it fails on "import com.google.appengine.api" (it doesn't know what 'com' is). For Sinatra, I use "Rerun" ( http://github.com/alexch/rerun ) which restarts server immediately after a change with minimum wait. Thanks.

  • Transform any JavaScript function into a page event

    - by Laith
    I need to be able to achieve the following (one way or another): function ShowContent() {} document.onShowContent = function () { // anything I want to happen.... } What I'm trying to do is to add a kind of listener to me Advertisement code on the page that will auto refresh the ad slot when a specific function is called. Instead of having that function "ShowContent()" directly refresh the ad code, I want the ad code to refresh if it detects that "ShowContent()" has been called. Thanks.

  • compile wxWidget on Snow Leopard

    - by Quincy
    I just downloaded wxWidget source code on my snow leopard machine. The source code is the multiplatform one, so it contains windows and GTK components of wxWidget as well. I'd like to compile the wxWidget source code, but haven't found a good guide yet. This is my first step to create a multiplatform project, hopefully I would be able to use CMake to generate makefile later on. Any help would be appreciated.

  • The fastest way to iterate through a collection of objects

    - by Trev
    Hello all, First to give you some background: I have some research code which performs a Monte Carlo simulation, essential what happens is I iterate through a collection of objects, compute a number of vectors from their surface then for each vector I iterate through the collection of objects again to see if the vector hits another object (similar to ray tracing). The pseudo code would look something like this for each object { for a number of vectors { do some computations for each object { check if vector intersects } } } As the number of objects can be quite large and the amount of rays is even larger I thought it would be wise to optimise how I iterate through the collection of objects. I created some test code which tests arrays, lists and vectors and for my first test cases found that vectors iterators were around twice as fast as arrays however when I implemented a vector in my code in was somewhat slower than the array I was using before. So I went back to the test code and increased the complexity of the object function each loop was calling (a dummy function equivalent to 'check if vector intersects') and I found that when the complexity of the function increases the execution time gap between arrays and vectors reduces until eventually the array was quicker. Does anyone know why this occurs? It seems strange that execution time inside the loop should effect the outer loop run time.

  • GPL License in closed source application

    - by Alec Smart
    Hello, This question has been asked multiple times I know. From what I understand, broadly speaking, if I include a GPL module in my app, I have to also release my app's source code for free. Now if the module is a java app (which I have modified) and included in my own java app, and say I use it as an applet on my website, do I need to distribute the source code to all the users visiting the website? Can I distribute the code only to people who ask for it? If I sell my applet, do I need to distribute the source code to all the users or ONLY to the users who purchase my applet? Thank you very much for your time.

  • Why does Microsoft advise against readonly fields with mutable values?

    - by Weeble
    In the Design Guidelines for Developing Class Libraries, Microsoft say: Do not assign instances of mutable types to read-only fields. The objects created using a mutable type can be modified after they are created. For example, arrays and most collections are mutable types while Int32, Uri, and String are immutable types. For fields that hold a mutable reference type, the read-only modifier prevents the field value from being overwritten but does not protect the mutable type from modification. This simply restates the behaviour of readonly without explaining why it's bad to use readonly. The implication appears to be that many people do not understand what "readonly" does and will wrongly expect readonly fields to be deeply immutable. In effect it advises using "readonly" as code documentation indicating deep immutability - despite the fact that the compiler has no way to enforce this - and disallows its use for its normal function: to ensure that the value of the field doesn't change after the object has been constructed. I feel uneasy with this recommendation to use "readonly" to indicate something other than its normal meaning understood by the compiler. I feel that it encourages people to misunderstand the meaning of "readonly", and furthermore to expect it to mean something that the author of the code might not intend. I feel that it precludes using it in places it could be useful - e.g. to show that some relationship between two mutable objects remains unchanged for the lifetime of one of those objects. The notion of assuming that readers do not understand the meaning of "readonly" also appears to be in contradiction to other advice from Microsoft, such as FxCop's "Do not initialize unnecessarily" rule, which assumes readers of your code to be experts in the language and should know that (for example) bool fields are automatically initialised to false, and stops you from providing the redundancy that shows "yes, this has been consciously set to false; I didn't just forget to initialize it". So, first and foremost, why do Microsoft advise against use of readonly for references to mutable types? I'd also be interested to know: Do you follow this Design Guideline in all your code? What do you expect when you see "readonly" in a piece of code you didn't write?

  • Giving another object a NSManagedObject

    - by Wayfarer
    Alright, so I'm running into an issue with my code. What I have done is subclassed UIButton so I can give it some more infomormation that pertain to my code. I have been able to create the buttons and they work great. Capiche. However, one of the things I want my subclass to hold is a reference to a NSMangedObject. I have this code in my header file: @interface ButtonSubclass : UIButton { NSManagedObjectContext *context; NSManagedObject *player; } @property (nonatomic, retain) NSManagedObject *player; @property (nonatomic, retain) NSManagedObjectContext *context; - (id)initWithFrame:(CGRect)frame andTitle:(NSString*)title; //- (void)setPlayer:(NSManagedObject *)aPlayer; @end As you can see, it has a instance variable to the NSMangedobject I want it to hold (as well as the Context). But for the life of me, I can't get it to hold that NSManagedObject. I run both the @synthesize methods in the Implementation file. @synthesize context; @synthesize player; So I'm not sure what I'm doing wrong. This is how I create my button: ButtonSubclass *playerButton = [[ButtonSubclass alloc] initWithFrame:frame andTitle:@"20"]; //works playerButton.context = self.context; //works playerButton.player = [players objectAtIndex:i]; //FAILS And I have initilaized the players array earlier, where I get the objects. Another weird thing is that when it gets to this spot in the code, the app crashes (woot) and the the console output stops. It doesn't give me any error, and notification at all that the app has crashed. It just... stops. So I don't even know what the error is that is crashing the code, besides it has to do with that line up there setting the "player" variable. Thoughts and ideas? I'd love your wisdom!

  • How to test silverlight behaviors using Rhino Mocks?

    - by Derek
    I have slightly adapted the custom behavior code that can be found here: http://www.reflectionit.nl/blog/default.aspx?guid=d81a8cf8-0345-48ee-bbde-84c2e3f21a25 that controls a MediaElement. I need to know how to go about testing this with Rhino Mocks e.g. how to instantiate a new ControlMediaElementAction in test code and then call the Invoke method etc. Doing something simple like this in test code: mMediaElementControlBehaviour = new ControlMediaElementAction (); gives me an exception "The type initializer for 'System.Windows.DependencyObject' throw an exception. Thinking it was the instantiation of the MediaElement, I tried this two lines of code: MediaElement mediaElementStub = MockRepository.GenerateStub(); this.Container.RegisterInstance(mediaElementStub); This gave the exception 'Can't create mocks of sealed classes' If someone can point me in the right direction, it would be apreciated. Silverlight 4, Rhino Mocks 3.5 Silverlight v2.0.50727 Thanks,

  • C# DLL Deployed in COM+. Error while accessing the methods.

    - by Dakshinamurthy
    I have the C# Dll (ABService) deployed in COM + and my os Is windows 2008. I have given the strong name for this dll and its dependent dll’s When I access the method of this dll through localhost or if I add the reference to the client project the method are executed successfully. Simply if I access the dll from the same machine with the reference it is working. So I think there is no problem with the way I deployed in the COM +. I have the doubt whether I have the problem in OS and Visual Studio 2008 combination. I have built all the dll with the Visual Studio 2008 with Target cpu as x86 and targert framework as 2.0. I have given in below the codes I have tried with and the errors. I need to create the object for the dll in server machine(64 bit) and access its method from the client(32 bit) Code : Type svr = Type.GetTypeFromProgID("ABService.Service", strserver1url[2],false); ABService.Service service1= (ABService.Service)Activator.CreateInstance(svr); strresult = service1.ExecuteService(orequest.xml); Error :{"Retrieving the COM class factory for remote component with CLSID {77BF00E0-41AC-3967-9E72-A4927CC0B880} from machine 10.105.138.64 failed due to the following error: 80040154."} Code Type svr = Type.GetTypeFromProgID("ABService.Service", strserver1url[2],true); object Service1 = null; Service1 = (ABService.Service)Activator.CreateInstance(svr, true); strresult = Convert.ToString(ReflectionHelper.Invoke(Service1, "ExecuteService", new object[] { orequest.xml })); Service1 = null; Error: Retrieving the COM class factory for remote component with CLSID {77BF00E0-41AC-3967-9E72-A4927CC0B880} from machine ftpsite failed due to the following error: 80040154. With the below code instead of C#.Net dll if i have the vb dll in Com + the method is executed successfully.
