  • How to use switch statement with Enumerations C#

    - by Maximus Decimus
    I want to use a switch statement in order to avoid many if's. So I did this: public enum Protocol { Http, Ftp } string strProtocolType = GetProtocolTypeFromDB(); switch (strProtocolType) { case Protocol.Http: { break; } case Protocol.Ftp: { break; } } but I have a problem of comparing an Enum and a String. So if I added Protocol.Http.ToString() there is another error because it allows only CONSTANT evaluation. If I change it to this switch (Enum.Parse(typeof(Protocol), strProtocolType)) It's not possible also. So, it's possible to use in my case a switch statement or not?

  • Get array of elements from event

    - by Anton
    I have few nested DIV elements. For example: <div id='id1'><div id='id2'>content</div></div> I attach event to DIVs event handler using jQuery: $('div').click(function () { //some code }); There will be two events when user click on content. So there will be two simultaneous events. Is it possible to get inside event handler array of objects (DIVs) what have click event? May be it is possible using other framework but jQuery?

  • How to Validate an XML Node against an XSD in C++?

    - by Ashish
    Hi Please note that I'm asking for validation against a particular node and not the whole file. For examples <somexmldoc> <someNode> <UserDefinedNode> </> <UserDefinedNode> </> </someNode> </somexmldoc> For this XML doc, I have an wholeDoc.XSD which could be used to validate the whole document except "UserDefinedNode" (This node is specified with "any" tag in xsd, which allows a user to define anything under that node). Is it possible to have a separate userdefined.XSD file to validate "UserDefinedNode"? Is it possible to use MSXML for C++ (IXMLDomDocument) to validate this? Thanks!

    - by m-abdi
    I have imported the ShockWave flash Activex Control in my Delphi project. I can manipulate All the properties of a Flash movie file. But I need to define my own Parameters in the my own Flash file and Manipulate those parameters in the Delphi project. I know that passing parameters to a flash file is possible in the HTML script. But my project is a desktop application and i can't use it. Is it possible to get a handle to the defined parameter of a flash file in the Delphi project? in fact All i need is passing parameter to flash file in the Delphi project.

  • Redirecting image to php page.

    - by Searock
    Hi, Is it possible to redirect a user to a php page and then redirect to different image, if the user is requesting for the image ? For example if user requests for the image or if other website requests for the image, it should be redirected to the php page and then redirected to a different image. Like if other website requests for http://example.com/images/a.gif, the website will get a different image i.e. http://example.com/images/b.gif. Is it possible? Let me know if I am not clear with my problem. Thanks. Edit : I am trying to create avatar changer for a forum, but the problem is that I cannot add a php link to my avatar. So I think if I could add a image link and when the forum requests the image I could redirect it internally to a php page and then from the php page I would redirect it to a different image.

  • Creating TCP network errors for unit testing

    - by Robert S. Barnes
    I'd like to create various network errors during testing. I'm using the Berkely sockets API directly in C++ on Linux. I'm running a mock server in another thread from within Boost.Test which listens on localhost. For instance, I'd like to create a timeout during connect. So far I've tried not calling accept in my mock server and setting the backlog to 1, then making multiple connections, but all seem to successfully connect. I would think that if there wasn't room in the backlog queue I would at least get a connection refused error if not a timeout. I'd like to do this all programatically if possible, but I'd consider using something external like IPchains to intentionally drop certain packets to certain ports during testing, but I'd need to automate creating and removing rules so I could do it from within my Boost.Test unit tests. I suppose I could mock the various system calls involved, but I'd rather go through a real TCP stack if possible. Ideas?

  • how to create a backup of a file once the current one is changed using php

    - by SkyLar
    I'm playing around with file info in php and i'm wondering if its possible to do the following: once a file is changed get the contents of the file, then put the contents of the file into another file. kinda like a "backup system" so once you make a change to the file a duplicate one is created, each change to the original file overwrites the duplicate one. i'm trying to do this with storing the time in the db, is this possible? i don't know what there is to test against? more clearly, i would like to do the following: execute a script once a specifeced file is changed on the server

  • Can layouts be chosen by Grails controllers?

    - by maerics
    I'm building a CMS as a learning exercise in Grails and would like to give content managers the ability to choose between different HTML page structures (e.g. 2 column, 3 column, etc). Grails Layouts seem like a logical choice but is it possible for a Grails controller to explicitly name which layout will be used for rendering? Ideally there would be a layout option to the render method, per Ruby on Rails but I don't see anything like it. It seems like it might be possible using the applyLayout method by passing the name of the layout but this requires each GSP page to explicitly request layout (annoying overhead per-page) rather than using Layout by Convention. Any ideas?

  • Threading Problems in ActionScript 2.0?

    - by yar
    Is it possible to have concurrency problems (thread competition) in an onEnterFrame method in ActionScript 2.0? I have written this cheesy code as a guard: if (!busy) { // I suspect some threading problems: is that even possible in flash busy = true; movePanels(); busy = false; } but this is no assurance against thread competition. If so, how can I do a basic semaphore/lock? Note: I suspect threading problems in my app, but if they're impossible, I'll check my code differently.

  • Reconstructing simple 3d enviroment(room) from photo

    - by Riz
    I have photo of a room with three walls and floor/ceiling or both. I am trying to reconstruct this room in 3d asking user for minimal input. Right now I use 8 points defined by user, angles of left and right wall(they can be quite different from 90) and one size "InLeftBottom-InRightBottom"(I need to have real size of this room for later use). I have no info about user's camera(I can read EXIF to get FOV and use constant height but this can be only used as additional info). Is this possible to ask user for less info? Maybe it's possible to get wall angles without user interaction? Or maybe I am completly wrong and should use different approach?

  • Align text with right edge of an html form

    - by williamjones
    I have an html form where the width of a textarea is specified with cols=. I want the textarea to have a specific width in terms of number of characters. However, I also want some controls to be right-justified to the right edge of the textarea. They're not in the textarea, but directly above or below it. Is it possible to do this? I was thinking a possible approach might be enclosing the textarea with some type of container that could grow to the width of the textarea, but I'm not sure how I could right-justify text within that.

  • How to assign a PHP variable that contains a mixed of PHP and html elements?

    - by Rick
    I have a PHP page that contains html and tags and PHP codes and I am using AJAX to manipulate some data and now I need to spit out the response but I am not sure if it is possible to put the mixed content into a string variable to pass through... Is this possible? For example I need to: $response = "<p>some text--<?php echo $something; ?>"; Thanks... To clear things up, I am not trying to send raw PHP code to clientside as that would be silly and won't be evaluated as it is a server side script. I am just looking for a fast way to put everything into a variable without manually re-doing the whole page stripping out the php open and close tags and echos...etc

  • Solving the problem of finding parts which work well with each other

    - by dotnetdev
    Hi, I have a database of items. They are for cars and similar parts (eg cam/pistons) work better than others in different combinations (eg one product will work well with another, while another combination of 2 parts may not). There are so many possible permutations, what solutions apply to this problem? So far, I feel that these are possible approaches (Where I have question marks, something tells me these are solutions but I am not 100% confident they are). Neural networks (?) Collection-based approach (selection of parts in a collection for cam, and likewise for pistons in another collection, all work well with each other) Business rules engine (?) What are good ways to tackle this sort of problem? Thanks

  • Managed HttpListener vs C++ Network Lib - Requires admin rights?

    - by Max
    So, I have noticed that starting an HttpListener is considered impolite according to Win 7. I cannot do so without administrative rights without adding myself to some URL reservation list. In theory, this is alright, but I'd like to make my program as little invasive as possible. My main other alternative is something like the c++ Network Library, which utilizes boost. This is probably not as simple as a HttpListener though. Will this circumvent the admin rights requirement for listening to some HTTP url? How does windows handle http listening? Right now I'm just listening to http://+:xxxx/url, I guess it's fully possible to just create a Socket listening at port xxxx and provide my own/third party http implementation?

  • Missing something with Entity Framework for .NET 3.5?

    - by AC
    Is it not possible to have EF create the necessary entities when I have two related tables linked with a FK in .NET3.5SP1? I see where the checkbox to support this is disabled but it is available in .NET4. I've got a DB that has only tables with relationships in it. I need to build a Silverlight app (SL4) that allows management of the data within this app. I can't use .NET4 on the server... only .NET3.5SP1 so FK relationship bit in EF4 isn't available to me. Looking to avoid building as much of the plumbing to get back to the DB from the SL4 app as possible...

  • Persisting non-entity class that extends an entity (jpa) - example?

    - by Michal Minicki
    The JPA tutorial states that one can have a non-entity that extends entity class: Entities may extend both entity and non-entity classes, and non-entity classes may extend entity classes. - http://java.sun.com/javaee/5/docs/tutorial/doc/bnbqa.html Is it possible to persist such structure? I want to do this: @Entity abstract class Test { ... } class FirstConcreteTest extends Test { ... } // Non-ntity class SecondConcreteTest extends Test { ... } // Non-entity Test test = new FirstConcreteTest(); em.persist(test); What I would like it to do is to persist all fields mapped on abstract Test to a common database table for all concrete classes (first and second), leaving all fields of first and second test class unpersisted (these can contain stuff like EJBs, jdbc pools, etc). And a bonus question. Is it possible to persist abstract property too? @Entity abstract class Test { @Column @Access(AccessType.PROPERTY) abstract public String getName(); } class SecondConcreteTest extends Test { public String getName() { return "Second Concrete Test"; } }

  • using an already proved lema/theorem/corollary in coq

    - by André Hincu
    I am trying to make a proof in Coq, and I would like to use a lemma already definded and proved by me. Is it possible for the following code? Lemma conj_comm: forall A B : Prop, A /\ B -> B /\ A. Proof. intros. destruct H. split. exact H0. exact H. Qed. Lemma not_conj_comm: forall A B : Prop, ~(A /\ B) -> ~(B /\ A). Proof. intros. intro. unfold not in H. apply H. use H0. In the above I want to use the fact that A /\B is the same as B /\ A in order to prove that ~(A /\ B) is the same as ~(B /\ A). Is it possible to use my proved lemma?

  • Android ListView highlight multiple items

    - by Tobias Kuess
    I want my ListView to change its background for each selected item (Multi-Selection). I used this code: <ListView ... android:drawSelectorOnTop="false" android:listSelector="@android:color/darker_gray" > This works fine, but it is just possible to select one single item of the list. If I select another one the selection is resetted and the new one changes its background. Is there an easy and fast way to make it possible to select more than one item at the same time with changing the background of every selected item?
