  • problems with infinite loop

    - by Tom
    function addAds($n) { for ($i=0;$i<=$n;$i++) { while($row=mysql_fetch_array(mysql_query("SELECT * FROM users"))) { $aut[]=$row['name']; } $author=$aut[rand(0,mysql_num_rows(mysql_query("SELECT * FROM users")))]; $name="pavadinimas".rand(0,3600); $rnd=rand(0,1); if($rnd==0) { $type="siulo"; } else { $type="iesko"; } $text="tekstas".md5("tekstas".rand(0,8000)); $time=time()-rand(3600,86400); $catid=rand(1,9); switch ($catid) { case 1: $subid=rand(1,8); break; case 2: $subid=rand(9,16); break; case 3: $subid=rand(17,24); break; case 4: $subid=rand(25,32); break; case 5: $subid=rand(33,41); break; case 6: $subid=rand(42,49); break; case 7: $subid=rand(50,56); break; case 8: $subid=rand(57,64); break; case 9: $subid=rand(65,70); break; } mysql_query("INSERT INTO advert(author,name,type,text,time,catid,subid) VALUES('$author','$name','$type','$text','$time','$catid','$subid')") or die(mysql_error()); } echo "$n adverts successfully added."; } The problem with this function, is that it never loads. As I noticed, my while loop causes it. If i comment it, everything is ok. It has to get random user from my db and set it to variable $author.

  • Efficient way to handle multiple HTMLPurifier configs.

    - by anomareh
    I'm using HTMLPurifier in a current project and I'm not sure about the most efficient way to go about handling multiple configs. For the most part the only major thing changing is the allowed tags. Currently I have a private method, in each class using HTMLPurifier, that gets called when a config is needed and it creates one from the default. I'm not really happy with this as if 2 classes are using the same config, that's duplicating code, and what if a class needs 2 configs? It just feels messy. The one upside to it, is it's lazy in the sense that it's not creating anything until it's needed. The various classes could be used and never have to purify anything. So I don't want to be creating a bunch of config objects that might not even be used. I just recently found out that you can create a new instance of HTMLPurifier and directly set config options like so: $purifier = new HTMLPurifier(); $purifier->config->set('HTML.Allowed', ''); I'm not sure if that's bad form at all or not, and if it isn't I'm not really sure of a good way to put it to use. My latest idea was to create a config handler class that would just return an HTMLPurifier config for use in subsequent purify calls. At some point it could probably be expanded to allow the setting of configs, but just from the start I figured they'd just be hardcoded and run a method parameter through a switch to grab the requested config. Perhaps I could just send the stored purifier instance as an argument and have the method directly set the config on it like shown above? This to me seems the best of the few ways I thought of, though I'm not sure if such a task warrants me creating a class to handle it, and if so, if I'm handling it in the best way. I'm not too familiar with the inner workings of HTMLPurifier so I'm not sure if there are any better mechanisms in place for handling multiple configs. Thanks for any insight anyone can offer.

  • WPF Image change source when button is disabled

    - by Taylor
    Hi, I'm trying to show a different image when the button is disabled. Should be easy with triggers, right?! For some reason, I have not been able to get the images to switch. I've tried setting triggers on both the image and button. What is wrong with what I have below? How can I change the image source when the button is enabled/disabled? Thanks! <Button x:Name="rleft" Command="{Binding Path=Operation}" CommandParameter="{x:Static vm:Ops.OpA}"> <Button.Content> <StackPanel> <Image Width="24" Height="24" RenderOptions.BitmapScalingMode="NearestNeighbor" SnapsToDevicePixels="True" Source="/MyAssembly;component/images/enabled.png"> <Image.Style> <Style> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=rleft, Path=Button.IsEnabled}" Value="False"> <Setter Property="Image.Source" Value="/MyAssembly;component/images/disabled.png" /> </DataTrigger> </Style.Triggers> </Style> </Image.Style> </Image> </StackPanel> </Button.Content> </Button>

  • Lightweight spinlocks built from GCC atomic operations?

    - by Thomas
    I'd like to minimize synchronization and write lock-free code when possible in a project of mine. When absolutely necessary I'd love to substitute light-weight spinlocks built from atomic operations for pthread and win32 mutex locks. My understanding is that these are system calls underneath and could cause a context switch (which may be unnecessary for very quick critical sections where simply spinning a few times would be preferable). The atomic operations I'm referring to are well documented here: http://gcc.gnu.org/onlinedocs/gcc-4.4.1/gcc/Atomic-Builtins.html Here is an example to illustrate what I'm talking about. Imagine a RB-tree with multiple readers and writers possible. RBTree::exists() is read-only and thread safe, RBTree::insert() would require exclusive access by a single writer (and no readers) to be safe. Some code: class IntSetTest { private: unsigned short lock; RBTree<int>* myset; public: // ... void add_number(int n) { // Aquire once locked==false (atomic) while (__sync_bool_compare_and_swap(&lock, 0, 0xffff) == false); // Perform a thread-unsafe operation on the set myset->insert(n); // Unlock (atomic) __sync_bool_compare_and_swap(&lock, 0xffff, 0); } bool check_number(int n) { // Increment once the lock is below 0xffff u16 savedlock = lock; while (savedlock == 0xffff || __sync_bool_compare_and_swap(&lock, savedlock, savedlock+1) == false) savedlock = lock; // Perform read-only operation bool exists = tree->exists(n); // Decrement savedlock = lock; while (__sync_bool_compare_and_swap(&lock, savedlock, savedlock-1) == false) savedlock = lock; return exists; } }; (lets assume it need not be exception-safe) Is this code indeed thread-safe? Are there any pros/cons to this idea? Any advice? Is the use of spinlocks like this a bad idea if the threads are not truly concurrent? Thanks in advance. ;)

  • rich:tabPanel and problems when filed has required="true"

    Hello, Let's consider following, simplified example: we have 2 tabs withing , each tab has and at the moment we want to switch from one tab to another, and the inputText is empty (we dont want to submit value from it anyway, we want to go to another tab) we get "Validation Error: Value is required." the example code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:a4j="http://richfaces.org/a4j" xmlns:rich="http://richfaces.org/rich" > <a4j:form id="mainForm" reRender="mainForm" ajaxSubmit="true" > <rich:tabPanel switchType="ajax"> <rich:tab label="TabA" > <a4j:region> <h:outputText value="Tab A content" /> <h:inputText value="" required="true" /> </a4j:region> </rich:tab> <rich:tab label="TabB"> <a4j:region> <h:outputText value="Tab B content" /> <h:inputText value="" required="true" /> </a4j:region> </rich:tab> </rich:tabPanel> <rich:messages /> </a4j:form> </html>

  • NSUserDefaults not saving properly

    - by BWC
    Hey Guys I'm having issues with NSUserDefaults and I don't quite understand what's going on My App has 5 levels and each level does the exact same thing with NSUserDefaults (Retrieves the levels defaults, changes the value as the user plays the level and then sets the defaults and syncronizes at the end of the level) the first 4 levels...work without a hitch but the last level doesn't save the values. The app doesn't crash and the last level isn't the very last thing that happens, And I even have the defaults synchronized when the application terminates. Is there a max size on the NSUserDefaults or is there anything anyone can think of that I haven't, I'll post the code below but like I said the first four levels work perfectly //header NSUserDefaults *userData; @property(nonatomic,retain) NSUserDefaults *userData; //class file //Sets the boolean variables for the class to use userData = [NSUserDefaults standardUserDefaults]; boolOne = [userData boolForKey:@"LevelFiveBoolOne"]; boolTwo = [userData boolForKey:@"LevelFiveBoolTwo"]; boolThree = [userData boolForKey:@"LevelFiveBoolThree"]; boolFour = [userData boolForKey:@"LevelFiveBoolFour"]; boolFive = [userData boolForKey:@"LevelFiveBoolFive"]; boolSix = [userData boolForKey:@"LevelFiveBoolSix"]; boolSeven = [userData boolForKey:@"LevelFiveBoolSeven"]; //End Of Level [userData setBool:boolOne forKey:@"LevelFiveBoolOne"]; [userData setBool:boolTwo forKey:@"LevelFiveBoolTwo"]; [userData setBool:boolThree forKey:@"LevelFiveBoolThree"]; [userData setBool:boolFour forKey:@"LevelFiveBoolFour"]; [userData setBool:boolFive forKey:@"LevelFiveBoolFive"]; [userData setBool:boolSix forKey:@"LevelFiveBoolSix"]; [userData setBool:boolSeven forKey:@"LevelFiveBoolSeven"]; [userData synchronize]; When when I switch to the view that uses these defaults they values are correct but when I terminate the application and restart it, these values aren't saved, every other level does the exact same process this is the only level that doesn't work. I've stared at this for quite awhile and I'm hoping someone out there has run into the same problem and can give me some insight on how they resolved it. Thank you in Advance BWC

  • WPF ValidationRule Validate when the control is loaded

    - by PaN1C_Showt1Me
    Hi ! I have a control with this validation <MyPicker.SelectedItem> <Binding Path="Person.Value" Mode="TwoWay" UpdateSourceTrigger="PropertyChanged" NotifyOnValidationError="True"> <Binding.ValidationRules> <rules:MyValidationRule ValidationType="notnull"/> </Binding.ValidationRules> </Binding> </MyPicker.SelectedItem> This is the Validation Class: class MyValidationRule : ValidationRule { private string _validationType; public string ValidationType { get { return _validationType; } set { _validationType = value; } } public override ValidationResult Validate(object value, CultureInfo cultureInfo) { ValidationResult trueResult = new ValidationResult(true, null); switch (_validationType.ToLower()) { case "notnull": return value == null ? new ValidationResult(false, "EMPTY FIELD") : trueResult; default: return trueResult; } } } Question: When the property is changed, then the Validate( ) method is called which is correct. But to call this method at the very beginning when the MyControl is created? I need to prove immediate after initialize if the there's a null value in the control (and display a validation error)

  • Core Data - Entity Relationships Not Working as expected

    - by slimms
    I have set up my data model in xcode like so EntityA AttA1 AttA2 EntityB AttB1 AttB2 AttB3 I then set up the relationships EntityA Name: rlpToEntityB Destination: EntityB Inverse: rlpToEntityA To Many: Checked EntityB Name: rlpToEntityA Destination: EntityA Inverse: rlpToEntityB To Many: UnChecked i.e. relationship between the two where Each one of EntityA can have many EntityB's It is my understanding that if i fetch a subset of EntityB's I can then retrieve the values for the related EntityA's. I have this working so that i can retrieve the EntityB values using NSManagedObject *objMO = [fetchedResultsController objectAtIndexPath:indexPath]; strValueFromEntityB = [objMO valueForKey:@"AttB1"]; However, if I try to retrieve a related value from EntityA by doing the following strValueFromEntityA = [objMO valueForKey:@"AttA1"]; I get the error "The entity EntityB is not Key value coding-compliant for the key Atta1" Not surprisingly i suppose if i switch things around to fetch from EntityA i cannot access attributes of EntityB So it appears the defined relationshipare being ignored. Can anyone spot what i am doing wrong? I confess im very new to iPhone programming and especially to Core Data so please go easy on me and provide verbose explanations or point me in the direction a specific resource. I have downloaded the apple sample apps (Core Data Books, Top Songs and recipes) but I still can't work this out. Thanks in advance, Nev.

  • Help me create a Firefox extension (Javascript XPCOM Component)

    - by Johnny Grass
    I've been looking at different tutorials and I know I'm close but I'm getting lost in implementation details because some of them are a little bit dated and a few things have changed since Firefox 3. I have already written the javascript for the firefox extension, now I need to make it into an XPCOM component. This is the functionality that I need: My Javascript file is simple, I have two functions startServer() and stopServer. I need to run startServer() when the browser starts and stopServer() when firefox quits. Edit: I've updated my code with a working solution (thanks to Neil). The following is in MyExtension/components/myextension.js. Components.utils.import("resource://gre/modules/XPCOMUtils.jsm"); const CI = Components.interfaces, CC = Components.classes, CR = Components.results; // class declaration function MyExtension() {} MyExtension.prototype = { classDescription: "My Firefox Extension", classID: Components.ID("{xxxx-xxxx-xxx-xxxxx}"), contractID: "@example.com/MyExtension;1", QueryInterface: XPCOMUtils.generateQI([CI.nsIObserver]), // add to category manager _xpcom_categories: [{ category: "profile-after-change" }], // start socket server startServer: function () { /* socket initialization code */ }, // stop socket server stopServer: function () { /* stop server */ }, observe: function(aSubject, aTopic, aData) { var obs = CC["@mozilla.org/observer-service;1"].getService(CI.nsIObserverService); switch (aTopic) { case "quit-application": this.stopServer(); obs.removeObserver(this, "quit-application"); break; case "profile-after-change": this.startServer(); obs.addObserver(this, "quit-application", false); break; default: throw Components.Exception("Unknown topic: " + aTopic); } } }; var components = [MyExtension]; function NSGetModule(compMgr, fileSpec) { return XPCOMUtils.generateModule(components); }

  • Faster image loading

    - by nemiss
    I want to display about 5-8 images on my page, one by one, but I would like them to pre-load one and not loading them each time i switch to anohter image. I have seen some examples where they have all images (hidden) on the page something like: <a href=""><img id="img1" src="images/image1.png" class="image" alt="" /></a> <a href=""><img id="img2" src="images/image1.png" class="image" alt="" /></a> <a href=""><img id="img3" src="images/image1.png" class="image" alt="" /></a> And the unhide the current image. And what I have is one image that i change it's src attribute for path for new images from th array. SwitchNextImage: function(){ var theimg=document.getElementById("imgContainer"); this.currentIndex = this.currentIndex+ 1 == this.totalImageCount ? 0 : this.currentIndex + 1; theimg.src=this.slideimages[this.currentIndex].src; } The first method is obviously faster loading. But requies static links. My questions is how can I make my method more faster loading?

  • Class; Struct; Enum confusion, what is better?

    - by Angel Brighteyes
    I have 46 rows of information, 2 columns each row ("Code Number", "Description"). These codes are returned to the client dependent upon the success or failure of their initial submission request. I do not want to use a database file (csv, sqlite, etc) for the storage/access. The closest type that I can think of for how I want these codes to be shown to the client is the exception class. Correct me if I'm wrong, but from what I can tell enums do not allow strings, though this sort of structure seemed the better option initially based on how it works (e.g. 100 = "missing name in request"). Thinking about it, creating a class might be the best modus operandi. However I would appreciate more experienced advice or direction and input from those who might have been in a similar situation. Currently this is what I have: class ReturnCode { private int _code; private string _message; public ReturnCode(int code) { Code = code; } public int Code { get { return _code; } set { _code = value; _message = RetrieveMessage(value); } } public string Message { get { return _message; } } private string RetrieveMessage(int value) { string message; switch (value) { case 100: message = "Request completed successfuly"; break; case 201: message = "Missing name in request."; break; default: message = "Unexpected failure, please email for support"; break; } return message; } }

  • How do we greatly optimize our MySQL database (or replace it) when using joins?

    - by jkaz
    Hi there, This is the first time I'm approaching an extremely high-volume situation. This is an ad server based on MySQL. However, the query that is used incorporates a lot of JOINs and is generally just slow. (This is Rails ActiveRecord, btw) sel = Ads.find(:all, :select = '*', :joins = "JOIN campaigns ON ads.campaign_id = campaigns.id JOIN users ON campaigns.user_id = users.id LEFT JOIN countries ON countries.campaign_id = campaigns.id LEFT JOIN keywords ON keywords.campaign_id = campaigns.id", :conditions = [flashstr + "keywords.word = ? AND ads.format = ? AND campaigns.cenabled = 1 AND (countries.country IS NULL OR countries.country = ?) AND ads.enabled = 1 AND campaigns.dailyenabled = 1 AND users.uenabled = 1", kw, format, viewer['country'][0]], :order = order, :limit = limit) My questions: Is there an alternative database like MySQL that has JOIN support, but is much faster? (I know there's Postgre, still evaluating it.) Otherwise, would firing up a MySQL instance, loading a local database into memory and re-loading that every 5 minutes help? Otherwise, is there any way I could switch this entire operation to Redis or Cassandra, and somehow change the JOIN behavior to match the (non-JOIN-able) nature of NoSQL? Thank you!

  • cakephp, i18n .po files, How to use them correctly

    - by ion
    I have finally managed to set up a multilingual cakephp site. Although not finished it is the first time where I can change the DEFAULT_LANGUAGE in the bootstrap and I can see the language to change. My problem right now is that I cannot understand very well how to use the po files correctly. According to the tutorials I've used I need to create a folder /app/locale and inside that folder create a folder for each language in the following format: /locale/eng/LC_MESSAGES. I have done that and I have also managed to extract a default.pot file using cake i18n extract. And it appears that all occurrences of the __() function have been found succesfully. In my application I'm using 2 languages: eng and gre. I can see why you would need a seperate folder for each language. However in my case nothing happens when I edit the po files inside each folder....well almost nothing. If I edit the /app/locale/gre/LC_MESSAGES/default.po I have no language changes. If I edit the /app/locale/eng/LC_MESSAGES/default.po then the language changes to the new value (on the translation field) and it does not switch to the other language. What am I doing wrong. I hope I made myself as clear as possible.

  • After Navigate2 Method returns S_OK Stuck at READYSTATE of READYSTATE_LOADING

    - by Stone Free
    I am working on a MFC Document View architecture application which has multiple documents and views and a tabbed window interface. I have been tasked with making an automatic switch to another tab on the press of the OK button in one of the other tabs. When the other tab is clicked on it uses a C++ wrapper over IWebBrowser2 to navigate to a specific web page. When this is done manually by clicking on the tab everything is fine and the webpage within the view loads successfully. In my first attempt at doing this the tab successfully switched in response to a call to AfxGetMainWnd()->SendMessageToDescendants(SOME_MESSAGE, ...); however by sending this windows message at the wrong point the application would crash once control returned because the chain of events caused the (modeless) dialog (*) that sent the message, to no longer exist. I then found the correct place to make the call, but now when the other tab is activated, it no longer displays the webpage as it should. To debug this problem I added code to check the READYSTATE in both the situation where it works and the situation where it does not. When the page fails to load (despite the call to Navigate2 returning S_OK), the READYSTATE just stays at READYSTATE_LOADING. Unfortunately now I am to many edits away from when I had it partially working. I have added TRACE statements to the most obvious events such as OnSetFocus, CView::OnActivateView but all traces come out in the same order despite the behaviour being different * hosted in the view

  • How to assign .net membership roles to individual database records

    - by mdresser
    I'm developing a system where we want to restrict the availability of information displayed to users based on their roles. e.g. I have a tabled called EventType (ID, EventTypeDescription) which contains the following records: 1, 'Basic Event' 2, 'Intermediate Event' 3, 'Admin Event' What I need to achieve is to filter the records returned based on the username (and hence role) of the logged-in user. e.g if an advanced user is logged in they will see all the event types, if the standard user is logged in they will only see the basic event type etc. Ideally id like to do this in a way which can be easily extended to other tables as necessary. So I'd like to avoid simply adding a 'Roles' field to each table where the data is user context sensitive. One idea I'm thinking of is to create some kind of permissions table like: PermissionsTable ( ID, Aspnet_RoleId, TableName, PrimaryKeyValue ) this has the drawback of using this is obviously having to use the table name to switch which table to join onto. Edit: In the absence of any better suggestions, I'm going to go with the last idea I mentioned, but instead of having a TableName field, I'm going to normalise the TableName out to it's own table as follows: TableNames ( ID, TableName ) UserPermissionsTable ( ID, Aspnet_UserId, TableID, PrimaryKeyValue )

  • Setcookie > sniff > output on same page

    - by lokust
    Hi, I wonder if someone can help shed some light on this: I drop a cookie if a user arrives to the site with a specific key/value in query string. i.e.: http://www.somesite.com?key=hmm01 The cookie code exists at top of the template before <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML ) : <?php header("Content-Type: text/html; charset=utf-8"); ob_start(); if (isset($_GET['key'])) { setcookie("cookname", $_GET['key'], time()+2592000); /* Expires in a month */ } ob_end_flush(); ?> On the same page though within the : I have the following php code that sniffs the cookie and outputs some text: ` switch ($cookievalue) { case hmm01: echo "abc"; break; case hmm02: echo "def"; break; case hmm03: echo "ghi"; break; default: echo "hello"; } ?` -- Problem is when the user first arrives the sniffer script doesn't detect the cookie and outputs the default text: hello Only when user refreshes page or navigates to a different page does the sniffer detect the cookie. Any ideas on how to drop the cookie and output the correct text without a page refresh? Many thanks.

  • NetBeans Tips and Tricks

    - by cdmckay
    I just saw an Eclipse tips & tricks post and was wondering if anyone had any tips & tricks for my IDE of choice: NetBeans. Here's a few I know and find to be useful: Removing a package: After you remove a package in NetBeans, it sticks around as a grayed-out package in your Project view. To get rid of that, switch to Files view and delete the directory. Alt-Insert (in Windows) opens up a Generate submenu at your cursor. A nice shortcut for quickly generating getters/setters (among other things). Selecting a chunk of code, right-clicking and then clicking "Refactor Introduce Method" will have NetBeans introduce a method, complete with arguments and return value. Of course you have to make sure the chunk of code only has one return value. Sometimes when you run a build and it crashes, the Java window sticks around at the bottom. I used to just click X until Windows let me End Task, but there's a nicer way to get rid of them. Click "Run Stop Build/Run" and NetBeans will close the window for you. It'll even let you close multiple applications at once. These may seem obvious to grizzled NetBeans developers, but I thought they might be useful for NetBeans newbs like me. Anyone else have any tips/tricks to share? Here are some from the comments: NetBeans allows for code templates. You can even add yours on the Code Templates tab under the Editor settings on the Options window. Some examples: Type sout and hit the tab key as a shorcut for System.out.println("") Type psvm and hit the tab key as a shorcut for public static void main(String args[]) {} Ctrl Shift C: Comments out the selected block of code. Alt Shift F: Formats the selected block of code. Ctrl E: Deletes current line. Ctrl Shift I: Fixes your imports, handy if you've just written a piece of code that needs a lot of packages imported.

This doesn't seem to work (based on 1809155): public class KeyAwareFlexTable extends FlexTable implements KeyDownHandler, HasKeyDownHandlers { public KeyAwareFlexTable() { this.addKeyDownHandler(this); } @Override public void onKeyDown(KeyDownEvent event) { GWT.log("onKeyDown"); // check if up/down & do something useful } @Override public HandlerRegistration addKeyDownHandler(KeyDownHandler handler) { return addDomHandler(handler, KeyDownEvent.getType()); } } I've also tried this (based on this site): FlexTable table = new FlexTable() { @Override public void onBrowserEvent(Event event) { super.onBrowserEvent(event); GWT.log("Event type = " + DOM.eventGetType(event)); switch (DOM.eventGetType(event)) { case Event.ONKEYDOWN: if (DOM.eventGetKeyCode(event) == KeyCodes.KEY_UP) { GWT.log("up"); } else if (DOM.eventGetKeyCode(event) == KeyCodes.KEY_DOWN) { GWT.log("down"); } break; default: break; } } }; table.sinkEvents(Event.ONKEYDOWN); I'm looking for a way to have this behavior more or less. Does anybody have a way to do this in GWT?

  • Reading from a file, atoi() returns zero only on first element

    - by Nazgulled
    Hi, I don't understand why atoi() is working for every entry but the first one. I have the following code to parse a simple .csv file: void ioReadSampleDataUsers(SocialNetwork *social, char *file) { FILE *fp = fopen(file, "r"); if(!fp) { perror("fopen"); exit(EXIT_FAILURE); } char line[BUFSIZ], *word, *buffer, name[30], address[35]; int ssn = 0, arg; while(fgets(line, BUFSIZ, fp)) { line[strlen(line) - 2] = '\0'; buffer = line; arg = 1; do { word = strsep(&buffer, ";"); if(word) { switch(arg) { case 1: printf("[%s] - (%d)\n", word, atoi(word)); ssn = atoi(word); break; case 2: strcpy(name, word); break; case 3: strcpy(address, word); break; } arg++; } } while(word); userInsert(social, name, address, ssn); } fclose(fp); } And the .csv sample file is this: 900011000;Jon Yang;3761 N. 14th St 900011001;Eugene Huang;2243 W St. 900011002;Ruben Torres;5844 Linden Land 900011003;Christy Zhu;1825 Village Pl. 900011004;Elizabeth Johnson;7553 Harness Circle But this is the output: [900011000] - (0) [900011001] - (900011001) [900011002] - (900011002) [900011003] - (900011003) [900011004] - (900011004) What am I doing wrong?

  • Toggle button and Toggle visibility

    - by danit
    I'm using this jQuery to hide a DIV: $("#slider").click(function() { $(".help").slideToggle(); $("#wrapper").animate({ opacity: 1.0 },200).slideToggle(200, function() { $("#slider a").text($(this).is(':visible') ? "Hide" : "Show"); }); }); Instead of altering the text show I want to display a graphic, I want the grpahic to change based on the .toggle Current HMTL: <div id="wrapper"> LI ITEMS </div> <div class="help"> IMAGE </div> <div id="slider"> <a href="#">Hide</a> </div> I'd like to add two images into .slider, removing the <a>: <div id="slider"> <img class="show" title="Hide" alt="Hide" src="images/showbutton.png" /> <img class="hide" title="Hide" alt="Hide" src="images/hidebutton.png" /> </div> Perhaps I can use css to hide the 'hide' button, then switch that using jquery in some way? Any suggestions?

  • osCommerce custom PHP page

    - by Afrosimon
    Hello! One of my client has an old osCommerce website and while working on it I have to implement what I would call "custom php page", i.e. a page which query a MySQL table, not related to osCommerce, and list the result. I'm not sure of the version, this trick I have seen a lot didn't gave me any result : http://www.clubosc.com/how-to-know-what-version-of-oscommerce-you-are-using.html . And I'm having a hard time doing this seemingly simple task, since osCommerce doesn't allow any php code in the page creation, and I didn't find any module giving me this possibility (not that it is easy to search in this mess : http://addons.oscommerce.com/). At this point I figured it would be easier to just hack'n slash through the code and come up with a custom page : I copied the index.php (the entry point in the application) : <?php require('includes/application_top.php'); if(!$smarty->is_cached($sContentPage, $sCachingGroup)) { //we switch on the content recognition require('includes/pages/' . $sContentClass . '.php'); } $smarty->display($sContentPage, $sCachingGroup); require(DIR_WS_INCLUDES . 'application_bottom.php'); ?> Here I gave a specific value to $sContentClass (with or without the if makes no difference) and customize the corresponding PHP file so it show my custom content but also initialize the same variable than those other PHP file in the pages/ folder. But alas, all of this curious and dubious code simply return me the home page. So here I am, is there an osCommerce Guru around here, or would anyone has a better idea (oh and I also posted on the osCommerce forum, but I'm still waiting for a response...)? Thanks a lot in advance.

  • Spring - How do you set Enum keys in a Map with annotations

    - by al nik
    Hi all, I've an Enum class public enum MyEnum{ ABC; } than my 'Mick' class has this property private Map<MyEnum, OtherObj> myMap; I've this spring xml configuration. <util:map id="myMap"> <entry key="ABC" value-ref="myObj" /> </util:map> <bean id="mick" class="com.x.Mick"> <property name="myMap" ref="myMap" /> </bean> and this is fine. I'd like to replace this xml configuration with Spring annotations. Do you have any idea on how to autowire the map? The problem here is that if I switch from xml config to the @Autowired annotation (on the myMap attribute of the Mick class) Spring is throwing this exception nested exception is org.springframework.beans.FatalBeanException: Key type [class com.MyEnum] of map [java.util.Map] must be assignable to [java.lang.String] Spring is no more able to recognize the string ABC as a MyEnum.ABC object. Any idea? Thanks
