  • Problems with MYSQL database

    - by shinjuo
    I have a database that worked fine until I decided to add a log onto the page. here is what I have now: <body> <?php if($_SERVER['REQUEST_METHOD'] == 'POST') { require("serverInfo.php"); mysql_query("UPDATE `cardLists` SET `AmountLeft` = `AmountLeft` + ".mysql_real_escape_string($_POST['Add'])."

  • Wordpress installed in root folder, subdomain now not working, GoDaddy host

    - by Kristin
    Hi, please forgive me for being a complete beginner at this, I'd rather not have to try to deal with this myself but as GoDaddy support have not replied after 2 days I'm going to have to. I think my problem is the same as the one above, but I'm not 100% sure, so I'm reposting it, I'm not really confident enough to attempt to try the fixes I've seen here so I need someone to give me baby instructions? Our original website (www.mwpics.com.au) was built in Dreamweaver etc, recently we created a new website in Wordpress, in a subdomain, then migrated it over to the root folder where it is now operating fine. I also moved the files for the old website into another directory which I called 'old', so they're all still there. The problem is that I have a subdomain set up - which is still showing as set up in the control panel on godaddy the url is www.mwpics.com.au/clients and it is at www.clients.mwpics.com.au. This directory contains loads of other directories, each of which is password protected by .htaccess files and which our clients access directly (not through the site) to download their finished work. The test one and the one for random clients is www.mwpics.com.au/clients/temp - username and password both temp (the usernames are all the same as the directory names). Since the WP install to the root directory the /clients extension no longer works (it should bring up an information page which is an .html index page in the directory) and the /clients/name extensions no longer works - it goes back to the wp site with a 'not found' error message. Strangely it does bring up the box for the username and password, but when you enter it it just goes back to the 'not found' message. Someone told me it was the .htaccess file - so as an experiment, I renamed the .htaccess file in the root directory and then copied the .htaccess file from the old root files into the root directory, eureka! It worked - and also the WP site opened to the home page... but bummer - the /pages in the WP site now no longer worked! But at least I know the source of the problem. So I switched it back and this is the status quo - I have no idea how to fix this, and with everyone back at work tomorrow, clients are going to want to start downloading their stuff... Can anyone help me? I'm starting to panic a bit

  • BULK INSERT from one table to another all on the server

    - by steve_d
    I have to copy a bunch of data from one database table into another. I can't use SELECT ... INTO because one of the columns is an identity column. Also, I have some changes to make to the schema. I was able to use the export data wizard to create an SSIS package, which I then edited in Visual Studio 2005 to make the changes desired and whatnot. It's certainly faster than an INSERT INTO, but it seems silly to me to download the data to a different computer just to upload it back again. (Assuming that I am correct that that's what the SSIS package is doing). Is there an equivalent to BULK INSERT that runs directly on the server, allows keeping identity values, and pulls data from a table? (as far as I can tell, BULK INSERT can only pull data from a file) Edit: I do know about IDENTITY_INSERT, but because there is a fair amount of data involved, INSERT INTO ... SELECT is kinda of slow. SSIS/BULK INSERT dumps the data into the table without regards to indexes and logging and whatnot, so it's faster. (Of course creating the clustered index on the table once it's populated is not fast, but it's still faster than the INSERT INTO...SELECT that I tried in my first attempt) Edit 2: The schema changes include (but are not limited to) the following: 1. Splitting one table into two new tables. In the future each will have its own IDENTITY column, but for the migration I think it will be simplest to use the identity from the original table as the identity for the both new tables. Once the migration is over one of the tables will have a one-to-many relationship to the other. 2. Moving columns from one table to another. 3. Deleting some cross reference tables that only cross referenced 1-to-1. Instead the reference will be a foreign key in one of the two tables. 4. Some new columns will be created with default values. 5. Some tables aren’t changing at all, but I have to copy them over due to the "put it all in a new DB" request.

  • ActionResult - Service

    - by cem
    I bored, writing same code for service and ui. Then i tried to write a converter for simple actions. This converter, converting Service Results to MVC result, seems like good solution for me but anyway i think this gonna opposite MVC pattern. So here, I need help, what you think about algorithm - is this good or not? Thanks ServiceResult - Base: public abstract class ServiceResult { public static NoPermissionResult Permission() { return new NoPermissionResult(); } public static SuccessResult Success() { return new SuccessResult(); } public static SuccessResult<T> Success<T>(T result) { return new SuccessResult<T>(result); } protected ServiceResult(ServiceResultType serviceResultType) { _resultType = serviceResultType; } private readonly ServiceResultType _resultType; public ServiceResultType ResultType { get { return _resultType; } } } public class SuccessResult<T> : ServiceResult { public SuccessResult(T result) : base(ServiceResultType.Success) { _result = result; } private readonly T _result; public T Result { get { return _result; } } } public class SuccessResult : SuccessResult<object> { public SuccessResult() : this(null) { } public SuccessResult(object o) : base(o) { } } Service - eg. ForumService: public ServiceResult Delete(IVUser user, int id) { Forum forum = Repository.GetDelete(id); if (!Permission.CanDelete(user, forum)) { return ServiceResult.Permission(); } Repository.Delete(forum); return ServiceResult.Success(); } Controller: public class BaseController { public ActionResult GetResult(ServiceResult result) { switch (result.ResultType) { case ServiceResultType.Success: var successResult = (SuccessResult)result; return View(successResult.Result); break; case ServiceResultType.NoPermission: return View("Error"); break; default: return View(); break; } } } [HandleError] public class ForumsController : BaseController { [ValidateAntiForgeryToken] [Transaction] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Delete(int id) { ServiceResult result = ForumService.Delete(WebUser.Current, id); /* Custom result */ if (result.ResultType == ServiceResultType.Success) { TempData[ControllerEnums.GlobalViewDataProperty.PageMessage.ToString()] = "The forum was successfully deleted."; return this.RedirectToAction(ec => Index()); } /* Custom result */ /* Execute Permission result etc. */ TempData[ControllerEnums.GlobalViewDataProperty.PageMessage.ToString()] = "A problem was encountered preventing the forum from being deleted. " + "Another item likely depends on this forum."; return GetResult(result); } }

  • Is there a way to enforce/preserve order of XML elements in an XML Schema?

    - by MarcoS
    Let's consider the following XML Schema: <?xml version="1.0" encoding="UTF-8"?> <schema targetNamespace="http://www.example.org/library" elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:lib="http://www.example.org/library"> <element name="library" type="lib:libraryType"></element> <complexType name="libraryType"> <sequence> <element name="books" type="lib:booksType"></element> </sequence> </complexType> <complexType name="booksType"> <sequence> <element name="book" type="lib:bookType" maxOccurs="unbounded" minOccurs="1"></element> </sequence> </complexType> <complexType name="bookType"> <attribute name="title" type="string"></attribute> </complexType> </schema> and a corresponding XML example: <?xml version="1.0" encoding="UTF-8"?> <lib:library xmlns:lib="http://www.example.org/library" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.example.org/library src/library.xsd "> <lib:books> <lib:book title="t1"/> <lib:book title="t2"/> <lib:book title="t3"/> </lib:books> </lib:library> Is there a way to guarantee that the order of <lib:book .../> elements is preserved? I want to be sure that any parser reading the XML will return books in the specified oder, that is first the book with title="t1", then the book with title="t2", and finally the book with title="t3". As far as I know XML parsers are not required to preserve order. I wonder whether one can enforce this through XML Schema? One quick solution for me would be adding an index attribute to the <lib:book .../> element, and delegate order preservation to the application reading the XML. Comments? Suggestions?

  • How to create a simple Proxy to access web servers in C

    - by jesusiniesta
    Hi. I’m trying to create an small Web Proxy in C. First, I’m trying to get a webpage, sending a GET frame to the server. I don’t know what I have missed, but I am not receiving any response. I would really appreciate if you can help me to find what is missing in this code. int main (int argc, char** argv) { int cache_size, //size of the cache in KiB port, port_google = 80, dir, mySocket, socket_google; char google[] = "www.google.es", ip[16]; struct sockaddr_in socketAddr; char buffer[10000000]; if (GetParameters(argc,argv,&cache_size,&port) != 0) return -1; GetIP (google, ip); printf("ip2 = %s\n",ip); dir = inet_addr (ip); printf("ip3 = %i\n",dir); /* Creation of a socket with Google */ socket_google = conectClient (port_google, dir, &socketAddr); if (socket_google < 0) return -1; else printf("Socket created\n"); sprintf(buffer,"GET /index.html HTTP/1.1\r\n\r\n"); if (write(socket_google, (void*)buffer, LONGITUD_MSJ+1) < 0 ) return 1; else printf("GET frame sent\n"); strcpy(buffer,"\n"); read(socket_google, buffer, sizeof(buffer)); // strcpy(message,buffer); printf("%s\n", buffer); return 0; } And this is the code I use to create the socket. I think this part is OK, but I copy it just in case. int conectClient (int puerto, int direccion, struct sockaddr_in *socketAddr) { int mySocket; char error[1000]; if ( (mySocket = socket(AF_INET, SOCK_STREAM, 0)) == -1) { printf("Error when creating the socket\n"); return -2; } socketAddr->sin_family = AF_INET; socketAddr->sin_addr.s_addr = direccion; socketAddr->sin_port = htons(puerto); if (connect (mySocket, (struct sockaddr *)socketAddr,sizeof (*socketAddr)) == -1) { snprintf(error, sizeof(error), "Error in %s:%d\n", __FILE__, __LINE__); perror(error); printf("%s\n",error); printf ("-- Error when stablishing a connection\n"); return -1; } return mySocket; } Thanks!

  • Spring MVC, REST, and HATEOAS

    - by SingleShot
    I'm struggling with the correct way to implement Spring MVC 3.x RESTful services with HATEOAS. Consider the following constraints: I don't want my domain entities polluted with web/rest constructs. I don't want my controllers polluted with view constructs. I want to support multiple views. Currently I have a nicely put together MVC app without HATEOAS. Domain entities are pure POJOs without any view or web/rest concepts embedded. For example: class User { public String getName() {...} public String setName(String name) {...} ... } My controllers are also simple. They provide routing and status, and delegate to Spring's view resolution framework. Note my application supports JSON, XML, and HTML, yet no domain entities or controllers have embedded view information: @Controller @RequestMapping("/users") class UserController { @RequestMapping public ModelAndView getAllUsers() { List<User> users = userRepository.findAll(); return new ModelAndView("users/index", "users", users); } @RequestMapping("/{id}") public ModelAndView getUser(@PathVariable Long id) { User user = userRepository.findById(id); return new ModelAndView("users/show", "user", user); } } So, now my issue - I'm not sure of a clean way to support HATEOAS. Here's an example. Let's say when the client asks for a User in JSON format, it comes out like this: { firstName: "John", lastName: "Smith" } Let's also say that when I support HATEOAS, I want the JSON to contain a simple "self" link that the client can then use to refresh the object, delete it, or something else. It might also have a "friends" link indicating how to get the user's list of friends: { firstName: "John", lastName: "Smith", links: [ { rel: "self", ref: "http://myserver/users/1" }, { rel: "friends", ref: "http://myserver/users/1/friends" } ] } Somehow I want to attach links to my object. I feel the right place to do this is in the controller layer as the controllers all know the correct URLs. Additionally, since I support multiple views, I feel like the right thing to do is somehow decorate my domain entities in the controller before they are converted to JSON/XML/whatever in Spring's view resolution framework. One way to do this might be to wrap the POJO in question with a generic Resource class that contains a list of links. Some view tweaking would be required to crunch it into the format I want, but its doable. Unfortunately nested resources could not be wrapped in this way. Other things that come to mind include adding links to the ModelAndView, and then customizing each of Spring's out-of-the-box view resolvers to stuff links into the generated JSON/XML/etc. What I don't want is to be constantly hand-crafting JSON/XML/etc. to accommodate various links as they come and go during the course of development. Thoughts?

  • Define Javascript slider hit/rollover area

    - by Rob
    Hey, Im having an issue defining the hit area for a javascript sliding element. See example: http://www.warface.co.uk/clients/warface.co.uk/ Please slide over the grey box on the right side to reveal the button, although this works I would only like for the slider to only be triggered by rolling over the red block. CSS .slidingtwitter { /* -- This is the hit area -- */ background: #ccc; width:255px; height:55px; overflow: hidden; top:50%; right: 0px; /* -- This is the sliding start point -- */ position: fixed; font-family: Gotham, Sans-Serif; z-index: 50; } .slidingtwitter.right { right:0px; } .slidingtwitter .caption { /* -- This is the sliding area -- */ background: #fff; position: absolute; width:260px; height:55px; right: -205px; /* -- This is the sliding start point -- */ } .slidingtwitter a { color: #484848; font-size: 20px; text-transform: uppercase; } .slidingtwitter a:hover { color: black; } .slidingtwitter .smaller { font-size: 12px; font-family: Gotham Medium; } .twitterblock { background: #f35555 url("styles/images/button_twitter.png") no-repeat 14px 15px ; width:35px; height:35px; padding:10px; float:left; display:block; } .slidingtwitter .followme { background: url("styles/images/button_arrowheadthin.jpg")no-repeat right 0; height:35px; display:block; float:left; line-height:14px; width:140px; margin:10px 0px 0px 14px; padding-top:6px; padding-right: 40px; } JS $('.slidingtwitter').hover(function(){ $(".slide", this).stop().animate({right:'0px'},{queue:false,duration:400}); //Position on rollover },function() { $(".slide", this).stop().animate({right:'-205px'},{queue:false,duration:400}); //Position on rollout }); Any suggestions would be much appreciated.

  • One Controller is Sometimes Bound Twice with Ninject

    - by Dusda
    I have the following NinjectModule, where we bind our repositories and business objects: /// <summary> /// Used by Ninject to bind interface contracts to concrete types. /// </summary> public class ServiceModule : NinjectModule { /// <summary> /// Loads this instance. /// </summary> public override void Load() { //bindings here. //Bind<IMyInterface>().To<MyImplementation>(); Bind<IUserRepository>().To<SqlUserRepository>(); Bind<IHomeRepository>().To<SqlHomeRepository>(); Bind<IPhotoRepository>().To<SqlPhotoRepository>(); //and so on //business objects Bind<IUser>().To<Data.User>(); Bind<IHome>().To<Data.Home>(); Bind<IPhoto>().To<Data.Photo>(); //and so on } } And here are the relevant overrides from our Global.asax, where we inherit from NinjectHttpApplication in order to integrate it with Asp.Net Mvc (The module lies in a separate dll called Thing.Web.Configuration): protected override void OnApplicationStarted() { base.OnApplicationStarted(); //routes and areas AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); //Initializes a singleton that must reference this HttpApplication class, //in order to provide the Ninject Kernel to the rest of Thing.Web. This //is necessary because there are a few instances (currently Membership) //that require manual dependency injection. NinjectKernel.Instance = new NinjectKernel(this); //view model factory. NinjectKernel.Instance.Kernel.Bind<IModelFactory>().To<MasterModelFactory>(); } protected override NinjectControllerFactory CreateControllerFactory() { return base.CreateControllerFactory(); } protected override Ninject.IKernel CreateKernel() { var kernel = new StandardKernel(); kernel.Load("Thing.Web.Configuration.dll"); return kernel; } Now, everything works great, with one exception: For some reason, sometimes Ninject will bind the PhotoController twice. This leads to an ActivationException, because Ninject can't discern which PhotoController I want. This causes all requests for thumbnails and other user images on the site to fail. Here is the PhotoController in it's entirety: public class PhotoController : Controller { public PhotoController() { } public ActionResult Index(string id) { var dir = Server.MapPath("~/" + ConfigurationManager.AppSettings["UserPhotos"]); var path = Path.Combine(dir, id); return base.File(path, "image/jpeg"); } } Every controller works in exactly the same way, but for some reason the PhotoController gets double-bound. Even then, it only happens occasionally (either when re-building the solution, or on staging/production when the app pool kicks in). Once this happens, it continues to happen until I redeploy without changing anything. So...what's up with that?

  • Hidden divs for "lazy javascript" loading? Possible security/other issues?

    - by xyld
    I'm curious about people's opinion's and thoughts about this situation. The reason I'd like to lazy load javascript is because of performance. Loading javascript at the end of the body reduces the browser blocking and ends up with much faster page loads. But there is some automation I'm using to generate the html (django specifically). This automation has the convenience of allowing forms to be built with "Widgets" that output content it needs to render the entire widget (extra javascript, css, ...). The problem is that the widget wants to output javascript immediately into the middle of the document, but I want to ensure all javascript loads at the end of the body. When the following widget is added to a form, you can see it renders some <script>...</script> tags: class AutoCompleteTagInput(forms.TextInput): class Media: css = { 'all': ('css/jquery.autocomplete.css', ) } js = ( 'js/jquery.bgiframe.js', 'js/jquery.ajaxQueue.js', 'js/jquery.autocomplete.js', ) def render(self, name, value, attrs=None): output = super(AutoCompleteTagInput, self).render(name, value, attrs) page_tags = Tag.objects.usage_for_model(DataSet) tag_list = simplejson.dumps([tag.name for tag in page_tags], ensure_ascii=False) return mark_safe(u'''<script type="text/javascript"> jQuery("#id_%s").autocomplete(%s, { width: 150, max: 10, highlight: false, scroll: true, scrollHeight: 100, matchContains: true, autoFill: true }); </script>''' % (name, tag_list,)) + output What I'm proposing is that if someone uses a <div class=".lazy-js">...</div> with some css (.lazy-js { display: none; }) and some javascript (jQuery('.lazy-js').each(function(index) { eval(jQuery(this).text()); }), you can effectively force all javascript to load at the end of page load: class AutoCompleteTagInput(forms.TextInput): class Media: css = { 'all': ('css/jquery.autocomplete.css', ) } js = ( 'js/jquery.bgiframe.js', 'js/jquery.ajaxQueue.js', 'js/jquery.autocomplete.js', ) def render(self, name, value, attrs=None): output = super(AutoCompleteTagInput, self).render(name, value, attrs) page_tags = Tag.objects.usage_for_model(DataSet) tag_list = simplejson.dumps([tag.name for tag in page_tags], ensure_ascii=False) return mark_safe(u'''<div class="lazy-js"> jQuery("#id_%s").autocomplete(%s, { width: 150, max: 10, highlight: false, scroll: true, scrollHeight: 100, matchContains: true, autoFill: true }); </div>''' % (name, tag_list,)) + output Nevermind all the details of my specific implementation (the specific media involved), I'm looking for a consensus on whether the method of using lazy-loaded javascript through hidden a hidden tags can pose issues whether security or other related? One of the most convenient parts about this is that it follows the DRY principle rather well IMO because you don't need to hack up a specific lazy-load for each instance in the page. It just "works". UPDATE: I'm not sure if django has the ability to queue things (via fancy template inheritance or something?) to be output just before the end of the </body>?

  • Trouble with ASP.NET MVC auto-scaffolder template

    - by DanM
    I'm trying to write an auto-scaffolder template for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IQueryable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. Here's what I have so far: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; // How do I make this generic? var properties = items.First().GetMetadata().Properties .Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm)); %> <table> <tr> <% foreach(var property in properties) { %> <th> <%= property.DisplayName %> </th> <% } %> </tr> <% foreach(var item in items) { HtmlHelper itemHtml = ????; // What should I put in place of "????"? %> <tr> <% foreach(var property in properties) { %> <td> <%= itemHtml.Display(property.DisplayName) %> </td> <% } %> </tr> <% } %> </table> Two problems with this: I'd like it to be generic. So, I'd like to replace var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; with var items = (IQueryable<T>)Model; or something to that effect. A property Html is automatically created for me when the view is created, but this HtmlHelper applies to the whole collection. I need to somehow create an itemHtml object that applies just to the current item in the foreach loop. I'm not sure how to do this, however, because the constructors for HtmlHelper don't take a Model object. How do I solve these two problems?

  • MooTools event listener disappears after element.innerHTML is changed

    - by acoder
    Hi everyone, I am trying to achieve this task using MooTools. Description: I attached an event listener to "myButton" link. A click on this link initiates an AJAX request and updates "myDiv" content based on the response text. During this request a POST variable is being sent to "button.php", but it's not used at the moment.. (i wish to use it later) OK, as a result, "myDiv" gets exactly the same link with the same ID (myButton) + a random number, so that we could see that each click generates a new number. The problem: After the first click on "myButton", "myDiv" updates correctly, showing a random number. When I click "myButton" for the second time (this time in newly updated div), the div does not refresh anymore. Please note that I need "myButton" to be inside "myDiv", and "myDiv" must be updated (refreshed) after each click without having to refresh the entire page. Can somebody show me how to achieve this task based on this simplified code example? index.html <html> <head> <script type="text/javascript" src="mootools-1.2.4-core-nc.js"></script> <script> window.addEvent('domready', function() { $('myButton').addEvent('click', function(e) { e.stop(); var myRequest = new Request({ method: 'post', url: 'button.php', data: { action : 'test' }, onRequest: function() { $('myDiv').innerHTML = '<img src="images/loading.gif" />'; }, onComplete: function(response) { $('myDiv').innerHTML = response; } }); myRequest.send(); $('myButton').removeEvent('click'); }); }); </script> </head> <body> <div id="myDiv"> <a id="myButton" href="#">Button</a> </div> </body> </html> button.php <a id="myButton" href="#">Button</a> clicked <?php echo rand(1,100); ?>

  • X264 encoding using Opencv

    - by user573193
    I am working with a high resolution camera: 4008x2672. I a writing a simple program which grabs frame from the camera and sends the frame to a avi file. For working with such a high resolution, I found only x264 codec that could do the trick (Suggestions welcome). I am using opencv for most of the image handling stuff. As mentioned in this post http://doom10.org/index.php?topic=1019.0 , I modified the AVCodecContext members as per ffmpeg presets for libx264 (Had to do this to avoid broken ffmpeg defaults settings error). This is output I am getting when I try to run the program [libx264 @ 0x992d040]non-strictly-monotonic PTS 1294846981.526675 1 0 //Timestamp camera_no frame_no 1294846981.621101 1 1 1294846981.715521 1 2 1294846981.809939 1 3 1294846981.904360 1 4 1294846981.998782 1 5 1294846982.093203 1 6 Last message repeated 7 times [avi @ 0x992beb0]st:0 error, non monotone timestamps -614891469123651720 = -614891469123651720 OpenCV Error: Unspecified error (Error while writing video frame) in icv_av_write_frame_FFMPEG, file /home/ajoshi/ext/OpenCV-2.2.0/modules/highgui/src/cap_ffmpeg.cpp, line 1034 terminate called after throwing an instance of 'cv::Exception' what(): /home/ajoshi/ext/OpenCV-2.2.0/modules/highgui/src/cap_ffmpeg.cpp:1034: error: (-2) Error while writing video frame in function icv_av_write_frame_FFMPEG Aborted Modifications to the AVCodecContext are: if(codec_id == CODEC_ID_H264) { //fprintf(stderr, "Trying to parse a preset file for libx264\n"); //Setting Values manually from medium preset c-me_method = 7; c-qcompress=0.6; c-qmin = 10; c-qmax = 51; c-max_qdiff = 4; c-i_quant_factor=0.71; c-max_b_frames=3; c-b_frame_strategy = 1; c-me_range = 16; c-me_subpel_quality=7; c-coder_type = 1; c-scenechange_threshold=40; c-partitions = X264_PART_I8X8 | X264_PART_I4X4 | X264_PART_P8X8 | X264_PART_B8X8; c-flags = CODEC_FLAG_LOOP_FILTER; c-flags2 = CODEC_FLAG2_BPYRAMID | CODEC_FLAG2_MIXED_REFS | CODEC_FLAG2_WPRED | CODEC_FLAG2_8X8DCT | CODEC_FLAG2_FASTPSKIP; c-keyint_min = 25; c-refs = 3; c-trellis=1; c-directpred = 1; c-weighted_p_pred=2; } I am probably not setting the dts and pts values which I believed ffmpeg should be setting it for me.

  • Having problems creating an array from XML data in Acrobat Javascript, please help if you can

    - by Kevin Minke
    I have a manually created array that already works example below: var PartsData = { 179: { ref:"", partNum: "201-2007-C00-00", descript: "System Monitor Card (Tracewell Only)", cage: "39764", qty: "1", SMR: "XBOZZ", UOC: "A" }}; Now this array above is is just one value in the array and it works fine. Here is the XML that I am trying to use to dynamically change the values. <?xml version="1.0" encoding="utf-8"?> <partsTables> <partsList> <part sheetNum="ta1"> <breakDownIndexNo>-1 </breakDownIndexNo> <referenceDesg/> <indent>20534220P01 </indent> <description/> <cage>TAC RI, GRADE-A SHOCK (TEC RACK), ALT P/N 72304-1</cage> <qtyPerAssy>23991 </qtyPerAssy> <smr>1 </smr> <uoc>ADODD </uoc> <blank/> </part> </partsList> </partsTables> I have this parsing just fine in Acrobat. Now I want to make the array work for me in using these values. if I have the following below it will work. Where part.item(i).indent.value equals the value of the indent node, etc. newArr = { 179: { ref: part.item(i).referenceDesg.value, partNum: part.item(i).indent.value, descript: part.item(i).cage.value, cage: part.item(i).qtyPerAssy.value, qty: part.item(i).smr.value, SMR: part.item(i).uoc.value, UOC: part.item(i).blank.value}}; As soon as I try to make the 179 value, which is in the breakDownIndexNo node, dynamic by using the direct part.item(i).breakDownIndexNo.value it will not compile. Acrobat is using javascript so I'm not sure why I can not get this to parse. I have tried to create a variable out of the breakDownIndexNo node and typed it to both a String and an Integer. this will let it create the array but it will not let me output from the array. newArr[indexNum].partNum gives me "no properties" where newArr[179].partNum if I were to manually set the index number to 179 will print out the value of part.item(i).indent.value. If any of you have an idea or an answer please let me know.

  • A case-insensitive related implementation problem

    - by Robert
    Hi All, I am going through a final refinement posted by the client, which needs me to do a case-insesitive query. I will basically walk through how this simple program works. First of all, in my Java class, I did a fairly simple webpage parsing: title=(String)results.get("title"); doc = docBuilder.parse("http://" + server + ":" + port + "/exist/rest/db/wb/xql/media_lookup.xql?" + "&title=" + title); This Java statement references an XQuery file "media_lookup.xql" which is stored on localhost, and the only parameter we are passing is the string "title". Secondly, let's take at look at that XQuery file: $title := request:get-parameter('title',""), $mediaNodes := doc('/db/wb/portfolio/media_data.xml'), $query := $mediaNodes//media[contains(title,$title)], Then it will evaluate that query. This XQuery will get the "title" parameter that are passes from our Java class, and query the "media_data" xml file stored in the database, which contains a bunch of media nodes with a 'title' element node. As you may expect, this simple query will just match those media nodes whose 'title' element contains a substring of what the value of string 'title' is. So if our 'title' is "Chi", it will return media nodes whose title may be "Chicago" or "Chicken". The refinment request posted by the client is that there should be NO case-sensitivity. The very intuitive way is to modify the XQuery statement by using a lower-case funtion in it, like: $query := $mediaNodes//media[contains(lower-case(title/text(),lower-case($title))], However, the question comes: this modified query will run my machine into memory overflow. Since my "media_data.xml" is quite huge and contains thouands of millions of media nodes, I assume the lower-case() function will run on each of the entries, thus causing the machine to crash. I've talked with some experienced XQuery programmer, and they think I should use an index to solve this problem, and I will definitely research into that. But before that, I am just posting this problem here to get other ideas or any suggestions, do you think any other way may help? for example, could I tweak the Java parse statement to realize the case-insensitivity? Since I think I saw some people did some string concatination by using "contains." in Java before passing it to the server. Any idea or help is welcomed, thanks in advance.

  • Having a Link Only Appear If a Logged-In User Appears on a Dynamic List

    - by John
    Hello, For the function below, I would like the link <div class="footervote"><a href="http://www...com/.../footervote.php">Vote</a></div> to only appear if the logged in user currently appears on editorlist.php. (I. e. if the loginid in the function corresponds to any of the usernames that currently appear in editorlist.php.) Appearing on editorlist.php is something that is dynamic. How can I do 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)?

  • Configuring a html page from an original demo page

    - by Wold
    I forked into rainyday.js through github, an awesome javascript program made by maroslaw at this link: https://github.com/maroslaw/rainyday.js. Basically I tried taking his demo page and my own photo city.jpg and changed the applicable fields so that I could run it on my own site, but only the picture loads and the script itself doesn't start to run. I'm pretty new to html and javascript so I'm probably omitting something very simple, but here is the script for the demo code: <script src="rainyday.js"></script> <script> function getURLParameter(name) { return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search)||[,''])[1].replace(/\+/g, '%20'))||null; } function demo() { var image = document.getElementById('background'); image.onload = function () { var engine = null; var preset = getURLParameter('preset') || '1'; if (preset === '1') { engine = new RainyDay({ element: 'background', blur: 10, opacity: 1, fps: 30, speed: 30 }); engine.rain([ [1, 2, 8000] ]); engine.rain([ [3, 3, 0.88], [5, 5, 0.9], [6, 2, 1] ], 100); } else if (preset === '2') { engine = new RainyDay({ element: 'background', blur: 10, opacity: 1, fps: 30, speed: 30 }); engine.VARIABLE_GRAVITY_ANGLE = Math.PI / 8; engine.rain([ [0, 2, 0.5], [4, 4, 1] ], 50); } else if (preset === '3') { engine = new RainyDay({ element: 'background', blur: 10, opacity: 1, fps: 30, speed: 30 }); engine.trail = engine.TRAIL_SMUDGE; engine.rain([ [0, 2, 0.5], [4, 4, 1] ], 100); } }; image.crossOrigin = 'anonymous'; if (getURLParameter('imgur')) { image.src = 'http://i.imgur.com/' + getURLParameter('imgur') + '.jpg'; } else if (getURLParameter('img')) { image.src = getURLParameter('img') + '.jpg'; } var youtube = getURLParameter('youtube'); if (youtube) { var div = document.getElementById('sound'); var player = document.createElement('iframe'); player.frameborder = '0'; player.height = '1'; player.width = '1'; player.src = 'https://youtube.com/embed/' + youtube + '?autoplay=1&controls=0&showinfo=0&autohide=1&loop=1'; div.appendChild(player); } } </script> This is where I am naming my background and specifying the photo from within the directory. <body onload="demo();"> <div id="sound" style="z-index: -1;"></div> <div id="parent"> <img id='background' alt="background" src="city.jpg" /> </div> </body> The actual code for the whole entire rainyday.js script can be found here: https://github.com/maroslaw/rainyday.js/blob/master/rainyday.js Thanks in advance for any help and advice!

  • OpenGL, how to set a monocrome texture to a colored shape?

    - by Santiago
    I'm developing on Android with OpenGL ES, I draw some cubes and I change its colors with glColor4f. Now, what I want is to give a more realistic effect on the cubes, so I create a monochromatic 8bit depth, 64x64 pixel size PNG file. I loaded on a texture, and here is my problem, witch is the way to combine the color and the texture to get a colorized and textured cubes onto the screen? I'm not an expert on OpenGL, I tried this: On create: public void asignBitmap(GL10 gl, Bitmap bitmap) { int[] textures = new int[1]; gl.glGenTextures(1, textures, 0); mTexture = textures[0]; gl.glBindTexture(GL10.GL_TEXTURE_2D, mTexture); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); gl.glTexEnvf(GL10.GL_TEXTURE_ENV, GL10.GL_TEXTURE_ENV_MODE, GL10.GL_REPLACE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_ALPHA, bitmap, 0); ByteBuffer tbb = ByteBuffer.allocateDirect(texCoords.length * 4); tbb.order(ByteOrder.nativeOrder()); mTexBuffer = tbb.asFloatBuffer(); for (int i = 0; i < 48; i++) mTexBuffer.put(texCoords[i]); mTexBuffer.position(0); } And OnDraw: public void draw(GL10 gl, int alphawires) { gl.glColor4f(1.0f, 0.0f, 0.0f, 0.5f); //RED gl.glBindTexture(GL10.GL_TEXTURE_2D, mTexture); gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); gl.glEnable(GL10.GL_TEXTURE_2D); gl.glEnable(GL10.GL_BLEND); gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, mTexBuffer); //Set the face rotation gl.glFrontFace(GL10.GL_CW); //Point to our buffers gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer); //Enable the vertex and color state gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); //Draw the vertices as triangles, based on the Index Buffer information gl.glDrawElements(GL10.GL_TRIANGLES, 36, GL10.GL_UNSIGNED_BYTE, indexBuffer); //Disable the client state before leaving gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glDisable(GL10.GL_BLEND); gl.glDisable(GL10.GL_TEXTURE_2D); } I'm even not sure if I have to use a blend option, because I don't need transparency, but is a plus :) Thank's

  • Layout issue regarding a JQuery smoothDivScroll

    - by MichaelMcCabe
    Hi all. I have been scratching my head for a while on this one. I dont really play around with HTML formatting that often. I have a smoothDivScroll using JQuery (http://maaki.com/thomas/SmoothDivScroll/) to scroll through dynamically generated images. What I want it for, is to have multiple small images lined up right next to each other, and each image has a section of writting underneath. about 25 images, 140px width each in a 7560px span. I acheived this great by putting a table inside the div, and each image inside a<td>.This works problem i have, is that i need the slider to start from the furthest RIGHT image, and slide automatically left. This is acheived by (if you look at the link above) - startAtElementId: But if I am using a table inside the div, it is taking the TABLE as a element and not the TD... so it doesnt work. I know this because if I change every image to be inside tables (i.e 25 tables), it works... but obviously then the formatting is not how I want. Can anyone think of a way I can use this slider (modifications to the js code or not), with 25 images that NEED to be right next to each other, no gap. I guess this is more of a formatting question, than about the slider. Because I only know ONE way of doing what I want, and thats to have below which will not alow me to set startAtElementId. <div class="scrollableArea"> <table width="7560px" class="index-body"> <tr> <td width="140px"><center><a onclick="__doPostBack('getEarlierDate');" ><img src="../images/olderGraphs.gif" width="140" height="60"></a>Click for more</center></td> <td width="300px"><center><a onclick="__doPostBack('chartClicked25');" ><cewolf:img chartid="verticalbar25" renderer="cewolf" width="300" height="60"/></a><c:out value="${date25}"/></center></td> <td width="300px"><center><a onclick="__doPostBack('chartClicked24');" ><cewolf:img chartid="verticalbar24" renderer="cewolf" width="300" height="60"/></a><c:out value="${date24}"/></center></td> and so on

  • Android browser touch events stop display being updated inc. canvas/elements - How to work around?

    - by Ed Kirk
    On some android's native browser touching the page seems to stop the display from being updated until the finger is released. This occurs for both html element based animation (switching classes) and for canvas based animation. It does not however stop normal js execution and other events are fired as normal. On devices with this problem the dolphin browser also seems effected (not firefox though). Touchstart/move both have preventDefault() fired as well as stopPropergation(), cancelBubble = true; and e.returnValue = false;. In the CSS webkit selection has also been disabled. The page will not scroll. A similar question has been asked here: Does Android browser lock DOM on touchStart? but I'd like to find out if this behaviour can be overcome, or at least to discover what devices will be effected by the problem, is it a device or version android issue? If you cannot answer the question running the demo and reporting your experience along with your device model and useragent (displayed at bottom of demo page) as a comment might help others or myself answer the question. Here is a demo and steps to reproduce the behaviour. A QR code for the link can be found here https://s3-eu-west-1.amazonaws.com/canvas-test-pd/tmp.png. https://s3-eu-west-1.amazonaws.com/canvas-test-pd/index.html The web page has a canvas at the top and a div with a background image at the bottom. Every second the canvas is cleared and a different image displayed and the div has it's class switched (both toggle between 0 and 1 pngs). Once this has toggled a few times place your finger on the canvas (the top grey box) and hold it there. Wait to see if the animation continues (sometimes it will once or twice then stops) and if there are any visual distortions. Update It seems that the Galaxy Tab running 3.2 requires handlers for touchstart/end of document, not just required divs for the screen to continue updating the display. Thanks jimpic. I'm starting to believe it's an issue caused by manufacturers skins, although this is difficult to prove.
