  • Clear Select options when selecting one field while using multiple forms on same page

    - by Nizam
    Hi all, I have a situation where the second select list option is generated from the first select list selected option. Like when we select Country corresponding states are generated in next select list. In my case I am having multiple forms on single page which are same. Can anyone let me know how to implement it on multiple forms. I tried the following code but it didn't work $(".country").change(function(){ $.get("sample.php?val=" + $(this).val(), function(data){ $(this).parent().next().children('.state').children('option').remove(); $(this).parent().next().children('.state').append(data); }); Waiting for your support thanks in advance

  • Simple WCF question.

    - by bearrito
    So I am learning WCF and I have run across an issue that I believe has to do with Instance Control/State but I am not sure. Workflow is as follows, Basic client/server paradigm. The client calls a Method RetrieveBusinessObjects(criteria) and the server calls the datalayer and then puts them in an IList on the server side. It does not return this list to the calling Client. The client would then call a method say DisplayBusinessObjects() which would retrieve the IList from the Server, serialize them, bring them across the wire and display them. If i try this using the WCFTestClient it works. If I run it from an actual client then I get back an BusinessObject[] of size 0. Which to me indicates I had no objects to return. Is that a state mgmt issue or am I missing something?

  • Atoms and references

    - by StackedCrooked
    According to the book Programming Clojure refs manage coordinated, synchronous changes to shared state and atoms manage uncoordinated, synchronous changes to shared state. If I understood correctly "coordinated" implies multiple changes are encapsulated as one atomic operation. If that is the case then it seems to me that coordination only requires using a dosync call. For example what is the difference between: (def i (atom 0)) (def j (atom 0)) (dosync (swap! i inc) (swap! j dec)) and: (def i (ref 0)) (def j (ref 0)) (dosync (alter i inc) (alter j dec))

  • Computer "Server"

    - by user328379
    so at home we had the idea of instead of buying 3 different pc's we would somehow create a "server" for the computers where a cable would come to our screens and keyboard and mouses, so the actual pc was somewhere else in the house with all the others. Does such a thing exist? And is it possible to have such a thing for high performance workflow? (Compiling, High-End Games, just as if it was a separate pc )

  • Why are functional languages considered a boon for multi threaded environments?

    - by Billy ONeal
    I hear a lot about functional languages, and how they scale well because there is no state around a function; and therefore that function can be massively parallelized. However, this makes little sense to me because almost all real-world practical programs need/have state to take care of. I also find it interesting that most major scaling libraries, i.e. MapReduce, are typically written in imperative languages like C or C++. I'd like to hear from the functional camp where this hype I'm hearing is coming from....

  • Best practice to test a web application, regarding domain name and integration with external service

    - by ycseattle
    I have run into these problems several times and was never able to find a comfortable solution. Let's say my website has the domain name MyDomain.com. When I run the tests on the test machine (a continuous integration server), I will modify the HOSTS file on this machine so the MyDomain.com is mapped to this local machine instead of the real production server. This doesn't work very well for many situations. For example, my application will create subdomain names user1.MyDomain.com dynamically but this is difficult to keep the testing flexible. Another problem is my web application will interact with Amazon S3, and sometimes other service like Amazon Simple Message Queue. I am only comfortable to include these interaction in my tests but I am never happy with my solution for mixing testing and production on Amazon services. Could somebody offer some tips on these issues? I would like to make my testing framework clean and flexible. I am sure this is a common question for all web applications and there must be a mature way to deal with these. Thanks!

  • Did anyone see the spasticNav.js Menu for jQuery ?

    - by Ricky
    Helooo all, If anyone doesn't know what i'm talking about, this is the link: http://net.tutsplus.com/tutorials/html-css-techniques/how-to-build-a-lava-lamp-style-navigation-menu/ How can i click the menu, and make it “stick” :) without reloading the whole page ? The plugin takes a static state of the tag UL – and run the plugin on it. which mean that if i move the “currentPageItem” from the first LI tag and give it to the next LI tag – the spasticNav doesn’t run for each object again. it still “remembers” the old state. ( because the .js file run only once at the top of the page ) So what should I add to the code in order to get dynamic “Click” event ? ( without reloading the whole page [ ajax ] ) Does anyone have any ideas about this specific plugin ? Thanks.

  • jQuery toggling divs, expand collapse all and keep first item selected when page loads

    - by hollyb
    Hi, I have a question about some functionality I'm trying to add to my jQuery to enable a button or text to expand/contract all the divs on click... and I'd like to figure out how to keep the first div open when the page loads. Here is the jQuery: (document).ready(function(){ //Hides containers on load $(".toggle_container").hide(); //Switch "Open" and "Close" state on click $("h2.trigger").toggle(function(){ $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); //Slide up and down on click $("h2.trigger").click(function(){ $(this).next(".toggle_container").slideToggle("slow"); }); }); And the css: // uses a background image with an on (+) and off (-) state stacked on top of each other h2.trigger { background: url(buttonBG.gif) no-repeat;height: 46px;line-height: 46px;width: 300px;font-size: 2em;font-weight: normal;} h2.trigger a {color: #fff;text-decoration: none; display: block;} h2.active {background-position: left bottom;} .toggle_container { overflow: hidden; } .toggle_container .block {padding: 20px;} And the html <h2 class="trigger"><a href="#">Heading</a></h2> <div class="toggle_container"> <div class="block">Stuff goes here</div> </div> <h2 class="trigger"><a href="#">Heading 2</a></h2> <div class="toggle_container"> <div class="block">Stuff goes here</div> </div> So it works great and looks great. However, when I try to get it to keep the first instance open, the background image that should adjust show the (-) state doesn't change. The code I used to this was: $(".toggle_container:first").show(); So, my question is, does anyone know of an easier way to show the first instance of this as open without having to created specials rules/class for the first item? Also, any ideas about how to make an open all/close all link? Thanks!

  • How to resize an openGL window created with wglCreateContext?

    - by Nick
    Is it possible to resize an openGL window (or device context) created with wglCreateContext without disabling it? If so how? Right now I have a function which resizes the DC but the only way I could get it to work was to call DisableOpenGL and then re-enable. This causes any textures and other state changes to be lost. I would like to do this without the disable so that I do not have to go through the tedious task of recreating the openGL DC state. HWND hWnd; HDC hDC; void View_setSizeWin32(int width, int height) { // resize the window LPRECT rec = malloc(sizeof(RECT)); GetWindowRect(hWnd, rec); SetWindowPos( hWnd, HWND_TOP, rec->left, rec->top, rec->left+width, rec->left+height, SWP_NOMOVE ); free(rec); // sad panda DisableOpenGL( hWnd, hDC, hRC ); EnableOpenGL( hWnd, &hDC, &hRC ); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(-(width/2), width/2, -(height/2), height/2, -1.0, 1.0); // have fun recreating the openGL state.... } void EnableOpenGL(HWND hWnd, HDC * hDC, HGLRC * hRC) { PIXELFORMATDESCRIPTOR pfd; int format; // get the device context (DC) *hDC = GetDC( hWnd ); // set the pixel format for the DC ZeroMemory( &pfd, sizeof( pfd ) ); pfd.nSize = sizeof( pfd ); pfd.nVersion = 1; pfd.dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL | PFD_DOUBLEBUFFER; pfd.iPixelType = PFD_TYPE_RGBA; pfd.cColorBits = 24; pfd.cDepthBits = 16; pfd.iLayerType = PFD_MAIN_PLANE; format = ChoosePixelFormat( *hDC, &pfd ); SetPixelFormat( *hDC, format, &pfd ); // create and enable the render context (RC) *hRC = wglCreateContext( *hDC ); wglMakeCurrent( *hDC, *hRC ); } void DisableOpenGL(HWND hWnd, HDC hDC, HGLRC hRC) { wglMakeCurrent( NULL, NULL ); wglDeleteContext( hRC ); ReleaseDC( hWnd, hDC ); }

  • Basic Team Foundation Server 2010 Question - System Resource Usage?

    - by user127954
    Guys / Gals i have a real basic Team Foundation Server 2010 question. For those of you who have played around with tfs 2010 is it a lot more light weight than tfs2008 is? I remember installing all the pieces needed for TFS 2008 one one machine at work. I remember it being a pain to install (i know 2010 is supposed to be much better) We wanted to play around with it a little bit to see if it met our needs. Well it brought that machine to a screeching halt. I'm needing a source control repository for home and i thought why not just install tfs 2010 so i can get familiar with it and maybe in the future i can make a better sell to my organization and FINALLY get them to move off of Source Safe but my concern is i only have one server at home (granted i already have SQL Server installed) and don't want to buy a machine just for this purpose. I'd also like to get more familiar with CI too. Anyways, if team is going to be to heavy i'll just use subversion but i'd like to use TFS if possible. Any help would be appreciated. thanks, Ncage

The last alert shows that the value of the bool variable is "true". However, when I do page source views of the hidden variable, below is the result. The values of the hidden variable when the page loads and when the last alert button finishes are as follows: My local machine: The remote machine: As you can see, the value on my machine is set to true when the process executes. However, on the remote machine, it is set to false where it then doesn't excute. Why isn't the value in the model being returned as TRUE on the remote machine?

  • Does Seaside scale?

    - by Richard Durr
    Seaside is known as "the heretical web framework". One of the points that make it heretical is that it has much shared state. That however is something which, in my current understanding, hinders easy scaling. Ruby on rails on the other hand shares as less state as possible. It has been known to scale pretty well, even if it is dog slow compared to modern smalltalk vms. flickr uses php and has scaled to an extremly big infrastructure... So has anybody some experience in the scaling of Seaside?

  • Hibernate multi column discriminator

    - by shikarishambu
    I have a single lookup table that manages all lookups - legacy and new lookup table structure is context,name, code, value context is either legacy or new name is the name of the lookup - state, status etc...for example code is the code and value is the value associated with the code Is there a way to specify multiple columns as discriminators so that I can get all legacy state code/values or all new status code/values. Is there a different way to do this if discriminators cannot do it? <class name="com.company.domain.Lookup"> <id name="Id" column="id" type="big_integer"> <generator class="org.hibernate.id.TableHiLoGenerator" /> </id> <discriminator column="context" insert="false" /> <property name="code" type="string"/> <property name="value" type="string"/> <property name="desc" type="string"/> <subclass name="com.company.domain.LegacyLookup" discriminator-value="legacy">

  • C++ game designing & polymorphism question

    - by Kotti
    Hi! I'm trying to implement some sort of 'just-for-me' game engine and the problem's plot goes the following way: Suppose I have some abstract interface for a renderable entity, e.g. IRenderable. And it's declared the following way: interface IRenderable { // (...) // Suppose that Backend is some abstract backend used // for rendering, and it's implementation is not important virtual void Render(Backend& backend) = 0; }; What I'm doing right now is something like declaring different classes like class Ball : public IRenderable { virtual void Render(Backend& backend) { // Rendering implementation, that is specific for // the Ball object // (...) } }; And then everything looks fine. I can easily do something like std::vector<IRenderable*> items, push some items like new Ball() in this vector and then make a call similiar to foreach (IRenderable* in items) { item->Render(backend); } Ok, I guess it is the 'polymorphic' way, but what if I want to have different types of objects in my game and an ability to manipulate their state, where every object can be manipulated via it's own interface? I could do something like struct GameState { Ball ball; Bonus bonus; // (...) }; and then easily change objects state via their own methods, like ball.Move(...) or bonus.Activate(...), where Move(...) is specific for only Ball and Activate(...) - for only Bonus instances. But in this case I lose the opportunity to write foreach IRenderable* simply because I store these balls and bonuses as instances of their derived, not base classes. And in this case the rendering procedure turns into a mess like ball.Render(backend); bonus.Render(backend); // (...) and it is bad because we actually lose our polymorphism this way (no actual need for making Render function virtual, etc. The other approach means invoking downcasting via dynamic_cast or something with typeid to determine the type of object you want to manipulate and this looks even worse to me and this also breaks this 'polymorphic' idea. So, my question is - is there some kind of (probably) alternative approach to what I want to do or can my current pattern be somehow modified so that I would actually store IRenderable* for my game objects (so that I can invoke virtual Render method on each of them) while preserving the ability to easily change the state of these objects? Maybe I'm doing something absolutely wrong from the beginning, if so, please point it out :) Thanks in advance!

  • What is the procedure for debugging a production-only error?

    - by Lord Torgamus
    Let me say upfront that I'm so ignorant on this topic that I don't even know whether this question has objective answers or not. If it ends up being "not," I'll delete or vote to close the post. Here's the scenario: I just wrote a little web service. It works on my machine. It works on my team lead's machine. It works, as far as I can tell, on every machine except for the production server. The exception that the production server spits out upon failure originates from a third-party JAR file, and is skimpy on information. I search the web for hours, but don't come up with anything useful. So what's the procedure for tracking down an issue that occurs only on production machines? Is there a standard methodology, or perhaps category/family of tools, for this? The error that inspired this question has already been fixed, but that was due more to good fortune than a solid approach to debugging. I'm asking this question for future reference. Some related questions: Test accounts and products in a production system Running test on Production Code/Server

  • Deploying a Rails app on an Ubuntu server using Git

    - by NudeCanalTroll
    I'm completely new to Linux, but today I find myself setting up a server (Ubuntu 10.04 LTS lucid) from scratch to host a Rails application. Anyway, I managed to get a Rails app up and running on the server itself, but I had to scrap that because I want to use Git. So I setup a git repository on the server, then pushed all the code from my local machine to the repository. Buuuut, of course Git doesn't actually store the files themselves in the repository -- all the code for my Rails app is now only on my local machine. How am I supposed to tell the server to host that? Right now my solution is to have the server use git to pull the code from its own repository. That's the code I'll host for all the world to see. In order to update the code, I guess I'll have to do something like this: Update the code on my local machine. Do some git adds, git commits, and a git push. On the server, do a git pull to update the code. So my question is, am I doing this the right way? enter code here

  • O'Reilly book clarification on 2d linear system

    - by Eric
    The Oreilly book "Learning openCV" states at page 356 : Quote Before we get totally lost, let’s consider a particular realistic situation of taking measurements on a car driving in a parking lot. We might imagine that the state of the car could be summarized by two position variables, x and y, and two velocities, vx and vy. These four variables would be the elements of the state vector xk. Th is suggests that the correct form for F is: x = [ x; y; vx; vy; ]k F = [ 1, 0, dt, 0; 0, 1, 0, dt; 0, 0, 1, 0; 0, 0, 0, 1; ] It seems natural to put 'dt' just there in the F matrix but I just don't get why. What if I have a n states system, how would I spray some "dt" in the F matrix?

  • Use HTTP PUT to create new cache (ehCache) running on the same Tomcat?

    - by socal_javaguy
    I am trying to send a HTTP PUT (in order to create a new cache and populate it with my generated JSON) to ehCache using my webservice which is on the same local tomcat instance. Am new to RESTful Web Services and am using JDK 1.6, Tomcat 7, ehCache, and JSON. I have my POJOs defined like this: Person POJO: import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Person { private String firstName; private String lastName; private List<House> houses; // Getters & Setters } House POJO: import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class House { private String address; private String city; private String state; // Getters & Setters } Using a PersonUtil class, I hardcoded the POJOs as follows: public class PersonUtil { public static Person getPerson() { Person person = new Person(); person.setFirstName("John"); person.setLastName("Doe"); List<House> houses = new ArrayList<House>(); House house = new House(); house.setAddress("1234 Elm Street"); house.setCity("Anytown"); house.setState("Maine"); houses.add(house); person.setHouses(houses); return person; } } Am able to create a JSON response per a GET request: @Path("") public class MyWebService{ @GET @Produces(MediaType.APPLICATION_JSON) public Person getPerson() { return PersonUtil.getPerson(); } } When deploying the war to tomcat and pointing the browser to http://localhost:8080/personservice/ Generated JSON: { "firstName" : "John", "lastName" : "Doe", "houses": [ { "address" : "1234 Elmstreet", "city" : "Anytown", "state" : "Maine" } ] } So far, so good, however, I have a different app which is running on the same tomcat instance (and has support for REST): http://localhost:8080/ehcache/rest/ While tomcat is running, I can issue a PUT like this: echo "Hello World" | curl -S -T - http://localhost:8080/ehcache/rest/hello/1 When I "GET" it like this: curl http://localhost:8080/ehcache/rest/hello/1 Will yield: Hello World What I need to do is create a POST which will put my entire Person generated JSON and create a new cache: http://localhost:8080/ehcache/rest/person And when I do a "GET" on this previous URL, it should look like this: { "firstName" : "John", "lastName" : "Doe", "houses": [ { "address" : "1234 Elmstreet", "city" : "Anytown", "state" : "Maine" } ] } So, far, this is what my PUT looks like: @PUT @Path("/ehcache/rest/person") @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) public Response createCache() { ResponseBuilder response = Response.ok(PersonUtil.getPerson(), MediaType.APPLICATION_JSON); return response.build(); } Question(s): (1) Is this the correct way to write the PUT? (2) What should I write inside the createCache() method to have it PUT my generated JSON into: http://localhost:8080/ehcache/rest/person (3) What would the command line CURL comment look like to use the PUT? Thanks for taking the time to read this...

I can get this to happen, but then it just goes back to its up state. I want it to stick on the down state, which I have to do by disabling the button. So I tried this: buttonList.selectedItem.enabled = false; for(var i:Number = 0; i< buttonList.numChildren; i++) { var loopBtn = buttonList.getChildAt(i); if(loopBtn != buttonList.selectedItem) { loopBtn.enabled = true; } } But this doesn't seem to work. What am I doing wrong here?

  • MySQL Can Connect Remotely but not Locally

    - by A Wizard Did It
    This is a weird problem and I'm not sure what's going on. I installed MySQL on a linux box I have running Ubuntu 10.04 LTS. I can access mysql via SSH mysql -p and perform all my commands that way. I added a user, and I can use AddedUser to connect remotely from my machine, but not from the local machine. It makes no sense to me... SELECT host, user FROM mysql.user Yields: +-----------+------------------+ | host | user | +-----------+------------------+ | % | AddedUser | | 127.0.0.1 | root | | li241-255 | root | | localhost | debian-sys-maint | | localhost | root | +-----------+------------------+ Problem is I'm developing on this machine using Node.js, and I can't connect locally from the server using the same username. I've tried FLUSH PRIVILEGES but that seems to have no effect. I know it's not Node.js because I'm using the same code on another database and it's working in that environment. Edit This is the error node is giving me. node.js:50 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: ECONNREFUSED, Connection refused at Stream._onConnect (net.js:687:18) at IOWatcher.onWritable [as callback] (net.js:284:12) Edit 2 I have the right port & server as best I can tell. My /etc/mysql/my.cnf contains this: port = 3306 socket = /var/run/mysqld/mysqld.sock My MySQL object contains: { host: 'localhost', port: 3306, user: 'removed', password: 'removed', database: '', typeCast: true, flags: 260047, maxPacketSize: 16777216, charsetNumber: 192, debug: false, ending: false, connected: false, _greeting: null, _queue: [], _connection: null, _parser: null, server: 'ExternalIpAddress' } Possibly useful? netstat -ln | grep mysql unix 2 [ ACC ] STREAM LISTENING 1016418 /var/run/mysqld/mysqld.sock

  • HD Crash SQL server -> DBCC - consistency errors in table 'sysindexes'

    - by Julian de Wit
    Hello A client of mine has had an HD crash an a SQL DB got corrupt : They did not make backups so they have a big problem. When I tried (an ultimate measure) to DBCC-repair I got the following message. Can anybody help me with this ? Server: Msg 8966, Level 16, State 1, Line 1 Could not read and latch page (1:872) with latch type SH. sysindexes failed. Server: Msg 8944, Level 16, State 1, Line 1 Table error: Object ID 2, index ID 0, page (1:872), row 11. Test (columnOffsets->IsComplex (varColumnNumber) && (ColumnId == COLID_HYDRA_TEXTPTR || ColumnId == COLID_INROW_ROOT || ColumnId == COLID_BACKPTR)) failed. Values are 2 and 5. The repair level on the DBCC statement caused this repair to be bypassed. CHECKTABLE found 0 allocation errors and 1 consistency errors in table 'sysindexes' (object ID 2). DBCC execution completed. If DBCC printed error messages, contact your system administrator.

  • How can I organize many results in a selectbox?

    - by zeckdude
    I have a select box that is part of a form. It is currently querying the addresses table and displaying the addresses into the select box. I plan on having up to 100 addresses. I'm looking for a solution where I can show all the states if the user clicks on the select box. Then if the user hovers over a state it will show all the addresses for that specific state. Then if the user clicks on an address, it will show that as the picked option in the select box. This is like a dropdown menu within a select box. Does anyone know where I can find a solution as this?

  • Java replacement for C macros

    - by thkala
    Recently I refactored the code of a 3rd party hash function from C++ to C. The process was relatively painless, with only a few changes of note. Now I want to write the same function in Java and I came upon a slight issue. In the C/C++ code there is a C preprocessor macro that takes a few integer variables names as arguments and performs a bunch of bitwise operations with their contents and a few constants. That macro is used in several different places, therefore its presence avoids a fair bit of code duplication. In Java, however, there is no equivalent for the C preprocessor. There is also no way to affect any basic type passed as an argument to a method - even autoboxing produces immutable objects. Coupled with the fact that Java methods return a single value, I can't seem to find a simple way to rewrite the macro. Avenues that I considered: Expand the macro by hand everywhere: It would work, but the code duplication could make things interesting in the long run. Write a method that returns an array: This would also work, but it would repeatedly result into code like this: long tmp[] = bitops(k, l, m, x, y, z); k = tmp[0]; l = tmp[1]; m = tmp[2]; x = tmp[3]; y = tmp[4]; z = tmp[5]; Write a method that takes an array as an argument: This would mean that all variable names would be reduced to array element references - it would be rather hard to keep track of which index corresponds to which variable. Create a separate class e.g. State with public fields of the appropriate type and use that as an argument to a method: This is my current solution. It allows the method to alter the variables, while still keeping their names. It has the disadvantage, however, that the State class will get more and more complex, as more macros and variables are added, in order to avoid copying values back and forth among different State objects. How would you rewrite such a C macro in Java? Is there a more appropriate way to deal with this, using the facilities provided by the standard Java 6 Development Kit (i.e. without 3rd party libraries or a separate preprocessor)?
