  • Special kind of queue

    - by devoured elysium
    I am looking for something like a Queue that would allow me to put elements at the end of the queue and pop them out in the beggining, like a regular Queue does. The difference would be that I also need to compact the Queue from time to time. This is, let's assume I have the following items on my Queue (each character, including the dot, is an item in the Queue): e d . c . b . a (this Queue has 8 items) Then, I'd need for example to remove the last dot, so to get: e d . c . b a Is there anything like that in the Java Collection classes? I need to use this for a program I am doing where I can't use anything but Java's classes. I am not allowed to design one for myself. Currently I'm just using a LinkedList, but I thought maybe this would be more like a Queue than a LinkedList. Thanks

  • Balanced File Distribution from server to client

    - by Abhinav
    To design a client-server code in LINUX where server will send the file equally to its entire client connected(all not at a time). Suppose 15 files are there, client1 makes a connection, server starts sending files to it. After 4 files a new connection comes the first client gets halted (not terminated) and client2 start getting the file. After 2 files another connection comes. Server starts sending file to client3. after sending 3[2(client2)+1] files, server resumes client2.then client2 & client3 goes on till file count reaches 4.then client1 wakeup & remaining 3 files are transferred to each 3 clients. File's name are pre written in a file from where server reads it(not a big deal)

  • PHP want to buy / find a eMall, Shopping Mall system with multiple vendor management backend

    - by Shiro
    Basically I am looking for a Shopping Mall system in PHP. User included Member / User Administrator Vendor Affiliate I find a lot ecommerce that support multiple shop, but each vendor don't have their own login and management. And in the front I would like to share the cart. and can buy from different shop. If multiple subdomain supported that would be more better. Web 2.0 design would be much more preferable. Any suggestion? I google some of it, hopefully can get more references. Buy / Open source also please advice. I don't think this kind of system got open source :p

  • Allow native DLL to output stdout / stderr in c# console application

    - by xaw
    I have a native DLL which outputs via stdout / stderr. I have a C# console application which calls this DLL and outputs binary data to a parent C# application which started the C# console exe, processing stdout / stderr. Currently when I call the C# exe it works just fine (the DLL hooks up to the stdout of my console application and puts its data in just fine). Is this by design (and shouldn't be broken in future .NET framework versions)? Are there limitations on my managed code's deployment with this strategy (full-trust, permission requirements, GAC issues, etc)? I can't seem to find any documentation about stdout with a managed exe and an unmanaged dll both putting data in that standard output on MSDN. Thanks,

  • Metatool for automatic xml code generation

    - by iceman
    I want to develop a programming tool for developers which can do automatic xml code generation for specifying a GUI design and its controls. The aim is to allow non-programmers specify GUI controls(which in this case perform higher level task unlike WinForms ) from a GUI. So the xml code generated is essentially an internal representation which programmers can understand and further use in any automatic GUI generator. So the workflow is GUI(non-programmers)-xml(for programmers)-GUI(non-programmers). Is there a Microsoft project similar to this?

  • iPhone: change height of UITableViewCell coming from a NIB

    - by Stefan Klumpp
    I have a UITableView of custom UITableViewCells which looks like this: [ CELL 0 [ description ] [ dynamic content type 1 ] [ dynamic content type 2 ] [ dynamic content type 3 ] ] [ CELL 1 [ description ] [ dynamic content type 1 ] [ dynamic content type 3 ] ] [ CELL 2 [ description ] [ dynamic content type 2 ] ] [ ... and so on ... ] Since the [description] part is already pretty complex I decided to use Interface Builder to design it and at add the [dynamic content] in the cellForRowAtIndexPath programmatically with [cell addSubview:...]. My problem is now, that I set a default height for my custom UITableViewCell in Interface Builder, but when I add my [dynamic content] (which might range between 0..3) I have different cells with different heights. One thing is of course to calculate the total height and change the return value in heightForRowAtIndexPath, but how do I change the height value of my actual cell (which was loaded from a nib file with a fixed height)?

  • How to organize asp.net mvc project (using entity framework) and a corresponding database project?

    - by Bernie
    I recently switched to vs2010 and am experimenting with asp.net MVC2. I am building a simple website and use the entity framework to design the data model. From the .edmx file, I generate the database tables. After a few iterations, I decided that it would be nice to have version control of the database schema as well, and therefore I added a database project into which I imported the script that is generated from the datamodel. As a result, I have to generate the sql every time that I change the model and redo the import. The database project automatically updates the database. Although the manual steps to generate the sql and the import are annoying, this works pretty well, until I wanted to add the standard tables for user accounts/authorization etc. I can use the framework tools to add the necessary tables, views etc. to the database, but as I do not want to have them in the .edmx model I end up with a third manual step. Is anybody facing similar issues?

  • Roles / Permissions framework for c#?

    - by mark smith
    Hi there, Does anyone know of a good framework to allow me design permission and roles against users. Basically allowing me to automatically check a user can do a certain thing, and then disabling or enabling menu items etc I am not really looking for asp.net security ... as i need to use it in my own service layer and clients both WEB and WPF will use it. I was hoping for something that allows me to create new roles and groups against users and then check what type of permissions a user has or a group has Any help really appreciated.. I am sure some kind of open source framework is available, well i was hoping not having to create my own Thanks

  • Is unit testing the definition of an interface necessary?

    - by HackedByChinese
    I have occasionally heard or read about people asserting their interfaces in a unit test. I don't mean mocking an interface for use in another type's test, but specifically creating a test to accompany the interface. Consider this ultra-lame and off-the-cuff example: public interface IDoSomething { string DoSomething(); } and the test: [TestFixture] public class IDoSomethingTests { [Test] public void DoSomething_Should_Return_Value() { var mock = new Mock<IDoSomething>(); var actualValue = mock.Expect(m => m.DoSomething()).Returns("value"); mock.Object.DoSomething(); mock.Verify(m => DoSomething()); Assert.AreEqual("value", actualValue); } } I suppose the idea is to use the test to drive the design of the interface and also to provide guidance for implementors on what's expected so they can draw good tests of their own. Is this a common (recommended) practice?

  • Equivalent of describeType for Flex Component EVENTS

    - by Joshua
    Using "introspection" In Flex I can say: var classInfo:XML=describeType(SomeObject); Which will list for me the Accessors, Methods And Variables. (http://livedocs.adobe.com/flex/3/html/help.html?content=usingas_8.html) But what is the equivalent to programmatically inspect all of an object's possible EVENTS? (NOT JUST the events for which event listeners have been set, but to somehow step through a list of all VALID EVENTS for which event listeners may POTENTIALLY be set -- I realize that such lists are readily available online, and that's great for cases when I know the object's type at design type, but I require some way to inspect any given displayobject programmatically at runtime, and determine what events, if any, are or may be associated with it.)

  • sql server 2005 reporting services-- how to use multiple datasets in report

    - by larryq
    Hi everyone, I'm new to SQL Server reporting services, and am trying to decipher an existing report. It's nothing too bad, but I notice it does have two report datasets defined. (They are generated via separate stored procedures) I'm trying to figure out where and how the report datasets are linked together so the Fields collection has both sets of columns available and the report has a single rowset to traverse. Is there a section in the report layout where a joining of datasets is defined? I'm using Visual Studio 2005 to design and preview the report fwiw. Thanks for your help!

  • How do you handle files that can't support concurrent edits in Mercurial?

    - by Scott Whitlock
    I'm using Mercurial with TortoiseHg. Each developer has their own repositories, and there's one central repository on the server for synchronizing our changes. (This will sound lame, but we're using it to manage the source for a legacy VB6 project. Nothing we can do about that...) As has been pointed out elsewhere, there is a big problem in VB6 with merging the .frx (form resources) files. So code changes seem to merge fine, but if two developers both make changes at the same time in the form design view, we can't merge. I'm ok with disallowing concurrent edits, but of course the whole point of Mercurial is that it's distributed so there is no option to force a file to be locked before editing. I don't believe there's a Mercurial solution for this, so I'm wondering: other developers who are using Mercurial for version control, do you have some 3rd party tool that assists with locking files for editing in the cases where it's necessary? Did we make a mistake using Mercurial instead of something like SVN?

  • Best Practice Guide: Swing

    - by wishi_
    Hi! Does anybody know Swing related GUI guidelines - specifically on how to design Swing apps and which components I should use? I'm not looking for an official standard, but pragmatic tips I can use to set a good standard for my projects. I haven't used too much of Swing by myself. Surely clicking a GUI with a GUI designer isn't a big deal. However I'd like to get some insights from people who have experience with Swing and know what to avoid. Swing lately (in Java 6- 10) got decent changes. So there isn't too much specific standardization out there currently.

  • How can I use my own connection class with a strongly typed dataset?

    - by Maslow
    I have designed a class with sqlClient.SqlCommand wrappers to implement such functionality as automatic retries on timeout, Async (thread safety), error logging, and some sql server functions like WhoAmI. I've used some strongly typed datasets mainly for display purposes only, but I'd like to have the same database functionality that I use with my class. Is there an interface I can implement or a way to hook my command/connection class into the dataset at design or runtime? Or would I need to somehow write a wrapper for the dataset to implement these types of functions? if this is the only option could it be made generic to wrap anything that inherits from dataset?

  • Why is memory management so visible in Java VM?

    - by Emil
    I'm playing around with writing some simple Spring-based web apps and deploying them to Tomcat. Almost immediately, I run into the need to customize the Tomcat's JVM settings with -XX:MaxPermSize (and -Xmx and -Xms); without this, the server easily runs out of PermGen space. Why is this such an issue for Java VMs compared to other garbage collected languages? Comparing counts of "tune X memory usage" for X in Java, Ruby, Perl and Python, shows that Java has easily an order of magnitude more hits in Google than the other languages combined. I'd also be interested in references to technical papers/blog-posts/etc explaining design choices behind JVM GC implementations, across different JVMs or compared to other interpreted language VMs (e.g. comparing Sun or IBM JVM to Parrot). Are there technical reasons why JVM users still have to deal with non-auto-tuning heap/permgen sizes?

  • How to gain greater control of network packets on Android

    - by mauvehead
    I'm looking to design an application that will require some deep control over IP packets. Looking over the reference guide on the developers site at Android I see very limited control over packets from java.net:SocketOptions and java.net:DatagramPacket. Specifically I'm looking to control the individual bits within the packet to set TCP Flags, SYN/ACK/RST, and so forth. Based on the docs I am assuming I cannot do this within the Java API provided by Android and I'm guessing I'll have to do it some other way? Anyone have any insight on this?

  • Merge overlapping triangles into a polygon

    - by nornagon
    I've got a bunch of overlapping triangles from a 3D model projected into a 2D plane. I need to merge each island of touching triangles into a closed, non-convex polygon. The resultant polygons shouldn't have any holes in them (since the source data doesn't). Many of the source triangles share (floating point identical) edges with other triangles in the source data. What's the easiest way to do this? Performance isn't particularly important, since this will be done at design time.

  • .NET: What is the purpose of the ProhibitDtd property in XmlReaderSettings? Why is DTD a security i

    - by Cheeso
    The documentation says: When set to true, the XmlReader throws an XmlException when any DTD content is encountered. Do not enable DTD processing if you are concerned about Denial of Service issues or if you are dealing with untrusted sources. If you have DTD processing enabled, you can use the XmlSecureResolver to restrict the resources that the XmlReader can access. You can also design your application so that the XML processing is memory and time constrained. For example, configure time-out limits in your ASP.NET application. Can someone please explain the issue? Why would a reader application want to prohibit the retrieval of a DTD? Where is the denial-of-service issue, if it is a reading application? What is the "trust" issue that is mentioned? Thanks

  • Where to Start with build a personal site and WordPress, CSS and CMS

    - by Simon
    Hey guys im in a very confused state of mind at the moment and need some help with Word Press and generally starting a website. My parents have had a business for 20 years and have finally decided to get a website! As im studying IT and Business i said id get it done for them. Rather than design it from scratch i used a template which i bought from themeforest.net (awesome template!) and yesterday a friend mentioned in passing using word press as a CMS which i had never heard of before, and he left before i could ask any questions. SO basically i have a site working on my computer and i have no idea how to get it live as a .com or .com.au, so far as i can see wordpress is a blog with .wordpress.com which isnt what im looking for. Thanks in advance Simon

  • VS2008 Complains about css class names it should know about

    - by Matt Dawdy
    I've seen this in a webcast somewhere, but I can't remember where, and all searching terms I'm trying are coming up unhelpful. I've got a stylesheet for my site, and it's referenced in a master page. Child pages that use this master page use these styles, but .Net doesn't know about them. When the site is run, it all works great, but I'm trying to figure out how to get .Net to know about them at design time. This should also fix the issue with not knowing about the javascript files I'm including, too -- I think it's all related and I can't for the life of me figure out how.

  • What Belongs to the Aggregate Root

    - by jlembke
    This is a practical Domain Driven Design question: Conceptually, I think I get Aggregate roots until I go to define one. I have an Employee entity, which has surfaced as an Aggregate root. In the Business, some employees can have work-related Violations logged against them: Employee-----*Violations Since not all Employees are subject to this, I would think that Violations would not be a part of the Employee Aggregate, correct? So when I want to work with Employees and their related violations, is this two separate Repository interactions by some Service? Lastly, when I add a Violation, is that method on the Employee Entity? Thanks for the help!

  • Why is SVN better than VSS? [closed]

    - by tsilb
    I've heard soooo many people complain about VSS, and noooo people complaining about SVN. We use SVN on my work project. It's slow, regularly freezes up my IDE, and has wonky behavior like looking for a database server every time I right-click the Solution node in my Solution Explorer. When I used VSS, everything worked beautifully, except for access restrictions which I of course blame on the people who control access. VSS is built by Microsoft and thus has great integration with Visual Studio. SVN is written by pretty much anybody with some free time (right?) and thus kinda works most of the time... And I honestly get the impression they had a dozen different directions in the design instead of one. So why do I keep hearing that SVN is better than VSS?

  • Ideal way to deliver large data over Web Services

    - by zengr
    We are trying to design 6 web services, which will serve another client component. The client component requires data from the web service we are implementing. Now, the problem is, there is not 1 WS we are implementing, there is one WS which the client component hits, this initiates a series (5 more) of WSs which gather data from their respective data stores and finally provide the data back to the original WS, which then delivers the data back to the client component. So, if the requested data becomes huge, then, this will be a serious problem for our internal communication channel. So, what do you guys suggest? What can be done to avoid overloading of the communication channel between the internal WS and at the same time, also delivering the data to the client component.

  • Jquery draggable persistence either through mysql or saving cookie in the database?

    - by Muhammad Jehanzaib
    I want to know that how can I persist the divs dropped on a draggable. I have been trying since long but stuck at this point. Actually you can see the demo here. I have to save the user designed wedding floor. So whenever user logins next time he/ she is able to see the last design saved. The code is shown below: $(document).ready(function() { $("#droppable").droppable({ accept: '.draggable', drop: function(event, ui) { $(this).append($(ui.draggable).clone()); $("#droppable .draggable").addClass("objects"); $(".objects").removeClass("ui-draggable draggable"); $(".objects").draggable({ containment: 'parent', }); } }); $(".draggable").draggable({ helper: 'clone', tolerance: 'touch', cursor:'move' }); });
