  • javascript exceed timeout

    - by user1866265
    I use jquery to develop mobile application, here is my code below the problem that when I add 5 or 6 line to the page contained all goes well. but if I add multiple line displays error message: Javascript execution exeeded timeout. function succes_recu_list_rubrique(tx, results) //apés avoire remplir sqlite { console.log('ENTRééééééééééééééé---') $('#lbtn').prepend("<legend>Selectionner un Rubrique</legend><br>"); for( var i=0; i<results.rows.length; i++ ) //Remplir tableau liste des identifiants étapes { $('#lbtn').append("<input name='opt1' checked type='radio' value="+results.rows.item(i).IdRubrique+" id="+results.rows.item(i).IdRubrique+" />"); $('#lbtn').append('<label for='+results.rows.item(i).IdRubrique+'>'+results.rows.item(i).LibelleRubrique+'</label>'); } $('#lbtn').append('<a href="#page_dialog2" class="offer2" data-rel="dialog" data-role="button" >Consulter</a>').trigger('create'); $('#lbtn').append('<a href="#'+id_grp_rub+'" data-role="button" data-rel="back" data-theme="c" >Cancel</a> ').trigger('create'); }

  • How to use IsKeyboardFocusWithin and IsSelected together?

    - by jpsstavares
    I have a style defined for my ListBoxItems with a trigger to set a background color when IsSelected is True: <Style x:Key="StepItemStyle" TargetType="{x:Type ListBoxItem}"> <Setter Property="SnapsToDevicePixels" Value="true"/> <Setter Property="OverridesDefaultStyle" Value="true"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListBoxItem"> <Border Name="Border" Padding="0" SnapsToDevicePixels="true"> <ContentPresenter /> </Border> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter TargetName="Border" Property="Background" Value="#40a0f5ff"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> This style maintains the selected item even when the ListBox and ListBoxItem loses focus, which in my case is an absolute must. The problem is that I also want the ListBoxItem to be selected when one of its TextBox's child gets focused. To achieve this I add a trigger that sets IsSelected to true when IsKeyboardFocusWithin is true: <Trigger Property="IsKeyboardFocusWithin" Value="True"> <Setter Property="IsSelected" Value="True" /> </Trigger> When I add this trigger the Item is selected when the focus is on a child TextBox, but the first behaviour disappears. Now when I click outside the ListBox, the item is de-selected. How can I keep both behaviours?

  • Should I define a single "DataContext" and pass references to it around or define muliple "DataConte

    - by Nate Bross
    I have a Silverlight application that consists of a MainWindow and several classes which update and draw images on the MainWindow. I'm now expanding this to keep track of everything in a database. Without going into specifics, lets say I have a structure like this: MainWindow Drawing-Surface Class1 -- Supports Drawing DataContext + DataServiceCollection<T> w/events Class2 -- Manages "transactions" (add/delete objects from drawing) Class3 Each "Class" is passed a reference to the Drawing Surface so they can interact with it independently. I'm starting to use WCF Data Services in Class1 and its working well; however, the other classes are also going to need access to the WCF Data Services. (Should I define my "DataContext" in MainWindow and pass a reference to each child class?) Class1 will need READ access to the "transactions" data, and Class2 will need READ access to some of the drawing data. So my question is, where does it make the most sense to define my DataContext? Does it make sense to: Define a "global" WCF Data Service "Context" object and pass references to that in all of my subsequent classes? Define an instance of the "Context" for each Class1, Class2, etc Have each method that requires access to data define its own instance of the "Context" and use closures handle the async load/complete events? Would a structure like this make more sense? Is there any danger in keeping an active "DataContext" open for an extended period of time? Typical usecase of this application could range from 1 minute to 40+ minutes. MainWindow Drawing-Surface DataContext Class1 -- Supports Drawing DataServiceCollection<DrawingType> w/events Class2 -- Manages "transactions" (add/delete objects from drawing) DataServiceCollection<TransactionType> w/events Class3 DataServiceCollection<T> w/events

  • How to pass a Dictionary variable to another procedure

    - by salvationishere
    I am developing a C# VS2008/SQL Server website application. I've never used the Dictionary class before, but I am trying to replace my Hashtable with a Dictionary variable. Here is a portion of my aspx.cs code: ... Dictionary<string, string> openWith = new Dictionary<string, string>(); for (int col = 0; col < headers.Length; col++) { @temp = (col + 1); @tempS = @temp.ToString(); @tempT = "@col" + @temp.ToString(); ... openWith.Add(@tempT, headers[col]); } ... for (int r = 0; r < myInputFile.Rows.Count; r++) { resultLabel.Text = ADONET_methods.AppendDataCT(myInputFile, openWith); } But this is giving me a compiler error on this last line: Argument '2': cannot convert from 'System.Collections.Generic.Dictionary' to 'string' How do I pass the entire openWith variable to AppendDataCT? AppendDataCT is the method that calls my SQL stored proc. I want to pass in the whole row where each row has a unique set of values that I want to add to my database table. For example, if each row requires values for cells A, B, and C, then I want to pass these 3 values to AppendDataCT, where all of these values are strings. How do I do this with Dictionary?

  • Is ADO.NET Entity framework database schema update possible ?

    - by fyasar
    Hi All I'm working on proof of concept application like crm and i need your some advice. My application's data layer completely dynamic and run onto EF 3.5. When the user update the entity, change relation or add new column to the database, first i'm planning make for these with custom classes. After I rebuild my database model layer with new changes during the application runtime. And my model layer tie with tightly coupled to my project for easy reflecting model layer changes (It connected to my project via interfaces and loading onto to application domain in the runtime). I need to create dynamic entities, create entity relations and modify them during the runtime after that i need to create change database script for updating database schema. I know ADO.NET team says "we will be able to provide this property in EF 4.0", but i don't need to wait for them. How can i update database changes during the runtime via EF 3.5 ? For example, i need to create new entity or need to change some entity schema, add new properties or change property types after than how can apply these changes on the physical database schema ? Any ideas ?

  • Java: Combine 2 List <String[]>

    - by battousai622
    I have two List of array string. I want to be able to create a New List (newList) by combining the 2 lists. But it must meet these 3 conditions: 1) Copy the contents of store_inventory into newList. 2) Then if the item names in store_inventory & new_acquisitions match, just add the two quantities together and change it in newList. 3) If new_acquisitions has a new item that does not exist in store_inventory, then add it to the newList. The titles for the CSV list are: Item Name, Quantity, Cost, Price. The List contains an string[] of item name, quantity, cost and price for each row. CSVReader from = new CSVReader(new FileReader("/test/new_acquisitions.csv")); List <String[]> acquisitions = from.readAll(); CSVReader to = new CSVReader(new FileReader("/test/store_inventory.csv")); List <String[]> inventory = to.readAll(); List <String[]> newList; Any code to get me started would be great! =] this is what i have so far... for (int i = 0; i < acquisitions.size(); i++) { temp1 = acquisitions.get(i); for (int j = 1; j < inventory.size(); j++) { temp2 = inventory.get(j); if (temp1[0].equals(temp2[0])) { //if match found... do something? //break out of loop } } //if new item found... do something? }

  • How to get a handle to all JCheckBox objects in order to loop?

    - by EmmyS
    I'm very new to Java and am having some issues looping through JCheckBoxes on a UI. The idea is that I have a bunch of checkboxes (not in a group because more than one can be selected.) When I click a JButton, I want to build a string containing the text from each selected checkbox. The issue I'm having is that our instructor told us that the checkboxes need to be created via a method, which means (see code below) that there isn't a discrete instance name for each checkbox. If there were, I could say something like if(checkBox1.isSelected()) { myString.append(checkBox.getText()); } That would repeat for checkBox2, checkBox3, and so on. But the method provided to us for adding checkboxes to a panel looks like this: public class CheckBoxPanel extends JPanel { private static final long serialVersionUID = 1L; public CheckBoxPanel(String title, String... options) { setBorder(BorderFactory.createTitledBorder(BorderFactory .createEtchedBorder(), title)); setLayout(new BoxLayout(this, BoxLayout.Y_AXIS)); // make one checkbox for each option for (String option : options) { JCheckBox b = new JCheckBox(option); b.setActionCommand(option); add(b); } } } This is called like this: toppingPanel = new CheckBoxPanel("Each Topping $1.50", "Tomato", "Green Pepper", "Black Olives", "Mushrooms", "Extra Cheese", "Pepperoni", "Sausage"); So I now have a panel that contains a border with the title "Each Topping $1.50", and 7 visible checkboxes. What I need to do is get a list of all the selected toppings. We are not supposed to use an ActionListener for each checkbox, but rather get the list when a button is clicked. I'm feeling really clueless here, but I just can't figure out how to get the isSelected property of the checkboxes when the individual checkboxes don't have instance names. Ideally I'd like to somehow add all the checkboxes to an array and loop through the array in the button's action listener to determine which ones are checked, but if I have to check each one individually I will. I just can't figure out how to refer to an individual checkbox when they've been created dynamically.

  • .Net assembly references being lost as soon as project is compiled

    - by Truegilly
    I have a windows service project, one of many C# projects in a solution file. I add a reference to my "Data_objects" class library for my windows service. this is added to the references no problem. all the classes become available and I can begin to code. As soon a I compile the windows service it says "The type or namespace name 'Data_Objects' could not be found (are you missing a using directive or an assembly reference?)" yet in the solution explorer the reference is fine, no yellow exclamation mark. I have to remove and add it again for it to pick it up, but then as soon as I compile it loses it. This reference works fine in my two other web application projects. what the hell is going on !! Truegilly Update there are no naming conflicts the only bit of code I have is a using statement - eg using Data_Objects.DataContext; also this only happens with a windows service project, i just created a new web app project and it works fine.

  • Best way to detect similar email addresses?

    - by Chris
    I have a list of ~20,000 email addresses, some of which I know to be fraudulent attempts to get around a "1 per e-mail" limit. ([email protected], [email protected], [email protected], etc...). I want to find similar email addresses for evaluation. Currently I'm using a levenshtein algorithm to check each e-mail against the others in the list and report any with an edit distance of less than 2. However, this is painstakingly slow. Is there a more efficient approach? The test code I'm using now is: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Threading; namespace LevenshteinAnalyzer { class Program { const string INPUT_FILE = @"C:\Input.txt"; const string OUTPUT_FILE = @"C:\Output.txt"; static void Main(string[] args) { var inputWords = File.ReadAllLines(INPUT_FILE); var outputWords = new SortedSet<string>(); for (var i = 0; i < inputWords.Length; i++) { if (i % 100 == 0) Console.WriteLine("Processing record #" + i); var word1 = inputWords[i].ToLower(); for (var n = i + 1; n < inputWords.Length; n++) { if (i == n) continue; var word2 = inputWords[n].ToLower(); if (word1 == word2) continue; if (outputWords.Contains(word1)) continue; if (outputWords.Contains(word2)) continue; var distance = LevenshteinAlgorithm.Compute(word1, word2); if (distance <= 2) { outputWords.Add(word1); outputWords.Add(word2); } } } File.WriteAllLines(OUTPUT_FILE, outputWords.ToArray()); Console.WriteLine("Found {0} words", outputWords.Count); } } }

  • Why am I having this InstantiationException in Java when accessing final local variables?

    - by Oscar Reyes
    I was playing with some code to make a "closure like" construct ( not working btw ) Everything looked fine but when I tried to access a final local variable in the code, the exception InstantiationException is thrown. If I remove the access to the local variable either by removing it altogether or by making it class attribute instead, no exception happens. The doc says: InstantiationException Thrown when an application tries to create an instance of a class using the newInstance method in class Class, but the specified class object cannot be instantiated. The instantiation can fail for a variety of reasons including but not limited to: - the class object represents an abstract class, an interface, an array class, a primitive type, or void - the class has no nullary constructor What other reason could have caused this problem? Here's the code. comment/uncomment the class attribute / local variable to see the effect (lines:5 and 10 ). import javax.swing.*; import java.awt.event.*; import java.awt.*; class InstantiationExceptionDemo { //static JTextField field = new JTextField();// works if uncommented public static void main( String [] args ) { JFrame frame = new JFrame(); JButton button = new JButton("Click"); final JTextField field = new JTextField();// fails if uncommented button.addActionListener( new _(){{ System.out.println("click " + field.getText()); }}); frame.add( field ); frame.add( button, BorderLayout.SOUTH ); frame.pack();frame.setVisible( true ); } } class _ implements ActionListener { public void actionPerformed( ActionEvent e ){ try { this.getClass().newInstance(); } catch( InstantiationException ie ){ throw new RuntimeException( ie ); } catch( IllegalAccessException ie ){ throw new RuntimeException( ie ); } } } Is this a bug in Java? edit Oh, I forgot, the stacktrace ( when thrown ) is: Caused by: java.lang.InstantiationException: InstantiationExceptionDemo$1 at java.lang.Class.newInstance0(Class.java:340) at java.lang.Class.newInstance(Class.java:308) at _.actionPerformed(InstantiationExceptionDemo.java:25)

  • How to apply CSS theme to only a specific jQuery-UI element?

    - by Thierry-Dimitri Roy
    I have a web site already build with my own CSS theme. I'm using jQuery UI "tabs" widget but no CSS from jQuery-UI. Now, I'm trying to add the "Date Picker" widget in one of my page. It would be great if I could reuse jQuery-UI default theme which is just fine. The problem is that the date picker theme is also applied to my tabs CSS. For example the "ui-widget" css properties is applied to both date picker and tabs elements. I can't seem to find a way to apply the css properties to only the date picker. I can't see a "super selector" that only applies to the date picker DIV. What would be the best way to handle this? [EDIT] The datepicker widget is really the problem. I cannot apply CSS style specific to it. Here is the starting code of the DIV that get pops up: <div style="position: absolute; top: 300.4px; left: 149px; display: block;" id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-helper-hidden-accessible"><div class="ui-datepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> As such, I cannot add a super selector. What would be great would be that the date picker widget supports CSS scope. But it does not. I'm stuck manually editing the jQuery CSS file. The Date Picker is currently being refactored. Hopefully the new code will address this issue.

  • php parsing speed optimization

    - by Arnaud
    I would like to add tooltip or generate link according to the element available in the database, for exemple if the html page printed is: to reboot your linux host in single-user mode you can ... I will use explode(" ", $row[page]) and the idea is now to lookup for every single word in the page to find out if they have a related referance in this exemple let's say i've got a table referance an one entry for reboot and one for linux reboot: restart a computeur linux: operating system now my output will look like (replaced < and by @) to @a href="ref/reboot"@reboot@/a@ your @a href="ref/linux"@linux@/a@ host in single-user mode you can ... Instead of have a static list generated when I saved the content, if I add more keyword in the future, then the text will become more interactive. My main concerne and question is how can I create a efficient enough process to do it ? Should I store all the db entry in an array and compare them ? Do an sql query for each word (seems to be crazy) Dump the table in a file and use a very long regex or a "grep -f pattern data" way of doing it? Or or or or I'm sure it must be a better way of doing it, just don't have a clue about it, or maybe this will be far too resource un-friendly and I should avoid doing such things. Cheers!

  • problem writing xml to file with .net mvc - timeout?

    - by Mark
    Hey, so having an issue with writing out to an xml file. Works fine for single requests via the browser, but when I use something like Charles to perform 5-10 repeated requests concurrently several of them will fail. The trace simply shows a 500 error with no content inside, basically I think they start timing out waiting for write access or something... This method is inside my repository class, have also attempted to have repository instance as a singleton but doesn't appear to make any difference.. Any help would be much appreciated. Cheers public void Add(Request request) { try { XDocument requests; XmlReader xmlReader; using (xmlReader = XmlReader.Create(_requestsFilePath)) { requests = XDocument.Load(xmlReader); XElement xmlRequest = new XElement("request", new XElement("code", request.code), new XElement("date", request.date), new XElement("email", new XCData(request.email)), new XElement("name", new XCData(request.name)), new XElement("recieveOffers", request.recieveOffers) ); requests.Root.Element("requests").Add(xmlRequest); xmlReader.Close(); } requests.Save(_requestsFilePath); } catch (Exception ex) { HttpContext.Current.Trace.Warn("Error writing to file: "+ex); } }

  • iOS MapKit: Selected MKAnnotation coordinates.

    Using the code at the following tutorial, http://www.zenbrains.com/blog/en/2010/05/detectar-cuando-se-selecciona-una-anotacion-mkannotation-en-mapa-mkmapview/, I was able to add an observer to each MKAnnotation and receive a notification of selected/deselected states. I am attempting to add a UIView on top of the selection annotation to display relevant information about the location. This information cannot be conveyed in the 2 lines allowed (Title/Subtitle) for the pin's callout. - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { Annotation *a = (Annotation *)object; // Alternatively attempted using: //Annotation *a = (Annotation *)[mapView.selectedAnnotations objectAtIndex:0]; NSString *action = (NSString *)context; if ([action isEqualToString:ANNOTATION_SELECTED_DESELECTED]) { BOOL annotationSelected = [[change valueForKey:@"new"] boolValue]; if (annotationSelected) { // Actions when annotation selected CGPoint origin = a.frame.origin; NSLog(@"origin (%f, %f) ", origin.x, origin.y); // Test UIView *v = [[UIView alloc] init]; [v setBackgroundColor:[UIColor orangeColor]]; [v setFrame:CGRectMake(origin.x, origin.y , 300, 300)]; [self.view addSubview:v]; [v release]; }else { // Accions when annotation deselected } } } Results using Annotation *a = (Annotation *)object origin (154373.000000, 197135.000000) origin (154394.000000, 197152.000000) origin (154445.000000, 197011.000000) Results using Annotation *a = (Annotation *)[mapView.selectedAnnotations objectAtIndex:0]; origin (0.000000, 0.000000) origin (0.000000, 0.000000) origin (0.000000, 0.000000) The numbers are large. They are not relative to the view (1024 x 768). I believe they are relative to the entire map. How would I be able to detect the exact coordinates relative to the entire view so that I can appropriately position my view?

  • Unobtrusive, self-hosted comments function to put onto existing web pages

    - by Pekka
    I am building a new site which will consist of a mix of dynamic and static pages. I would like to add commenting functionality to those pages with as little work as possible. I'm curious as to whether such a solution exists in PHP. The ideal set of features would be: Completely independent from the surrounding page / site: PHP code gets dropped into page, a page ID is added, done. Simple "write a comment" form Comments for each page are displayed using a PHP function Nice, clean output of <ul><li>.... that can be styled by the surrounding site Optional Captcha Optional Gravatar sensitivity Minimalistic administration area to moderate/delete comments, no ACL, can protect it using .htaccess The ideal integreation would be like this: <?php show_comments("my_page_name"); ?> this would 1. display a form to add a new comment that gets automatically associtated with my_page_name; and 2. display all comments that were made through this form using this ID. Does anybody know a solution like this? Bounty I am setting up a bounty because while there were some good suggestions, they all point to external services. I'm really curious to see whether there isn't anything self-hosted around. If this doesn't exist yet, it sure would be great to see as an Open Source project.

  • Passing an Ajax variable to a Codeigniter function

    - by Matt
    Hello, I think this is a simple one. I have a Codeigniter function which takes the inputs from a form and inserts them into a database. I want to Ajaxify the process. At the moment the first line of the function gets the id field from the form - I need to change this to get the id field from the Ajax post (which references a hidden field in the form containing the necessary value) instead. How do I do this please? My Codeigniter Controller function function add() { $product = $this->products_model->get($this->input->post('id')); $insert = array( 'id' => $this->input->post('id'), 'qty' => 1, 'price' => $product->price, 'size' => $product->size, 'name' => $product->name ); $this->cart->insert($insert); redirect('home'); } And the jQuery Ajax function $("#form").submit(function(){ var dataString = $("input#id") //alert (dataString);return false; $.ajax({ type: "POST", url: "/home/add", data: dataString, success: function() { } }); return false; }); As always, many thanks in advance.

  • Default Button after dispose and setVisible

    - by DaDaDom
    Hi, given the following code: public class DialogTest implements ActionListener { public static void main(String[] args) {DialogTest g = new DialogTest();} public DialogTest() { JButton b1 = new JButton("Button A"); b1.addActionListener(this); JDialog d = new JDialog(); d.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); JPanel p = new JPanel(); p.add(b1); d.add(p); d.getRootPane().setDefaultButton(b1); d.pack(); d.setVisible(true); d.dispose(); d.pack(); d.setVisible(true); } public void actionPerformed(ActionEvent e) {System.out.println("hello");} } Shouldn't pressing the Enter key write something to the console? According to the docs (http://java.sun.com/javase/7/docs/api/java/awt/Window.html#dispose()): The Window and its subcomponents can be made displayable again by rebuilding the native resources with a subsequent call to pack or show. The states of the recreated Window and its subcomponents will be identical to the states of these objects at the point where the Window was disposed Is this intended behaviour?

  • Why doesn't this simple regex match what I think it should?

    I have a data file that looks like the following example. I've added '%' in lieu of \t, the tab control character. 1234:56% Alice Worthington alicew% Jan 1, 2010 10:20:30 AM% Closed% Development Digg: Reddit: Update%% file-one.txt% 1.1% c:/foo/bar/quux Add%% file-two.txt% 2.5.2% c:/foo/bar/quux Remove%% file-three.txt% 3.4% c:/bar/quux Update%% file-four.txt% 4.6.5.3% c:/zzz ... many more records of the above form The records I'm interested in are the lines beginning with "Update", "Add", "Remove", and so on. I won't know what the lines begin with ahead of time, or how many lines precede them. I do know that they always begin with a string of letters followed by two tabs. So I wrote this regex: generate-report-for 1234:56 | egrep "^[[:alpha:]]+\t\t.+" But this matches zero lines. Where did I go wrong? Edit: I get the same results whether I use '...' or "..." for the egrep expression, so I'm not sure it's a shell thing.

    Hello, I have an issue with my ExternalInterface. The way it is currently set up is, on the page load up, a boolean is set to true in JavaScript and then checked by ActionScript constructors (using a timer) until it is true. This marks that JavaScript is ready to get calls from AS3. At this point, AS3 will add the callback and do some internal stuff, and at the end of the constructor I call JavaScript. So far so good. JavaScript will at this point call a function in AS3 (that was defined in the callback described above), and this is where it all messes up. On IE this works perfectly fine. On FireFox though, it does not. When I debug it, I see that the javascript function is called but when it tries to call AS3, nothing happens. I also tried to add a timer, but for some reason the function STILL executes straight away (in IE). What is very weird is that a second or two later, that function will work, so it seems that the Flash is not completely loaded in FireFox? But it runs to the last line of my constructor, so I would believe it's loaded. Any idea please, I am really stuck. Thanks a lot, Rudy

  • Silverlight datagrid fails to display data.

    - by Jekke
    I have a datagrid defined in my project's XAML: <data:DataGrid IsReadOnly="True" Grid.Row="1" Grid.Column="1" x:Name="gridOfferings" Margin="10,10,10,10" AutoGenerateColumns="False"> <data:DataGrid.Columns> <data:DataGridTextColumn Binding="{Binding Trader}" DisplayIndex="0" Header="Trader" Width="Auto" FontSize="11"/> <data:DataGridTextColumn Binding="{Binding Product}" DisplayIndex="1" Header="Product" Width="Auto" FontSize="11"/> </data:DataGrid.Columns> </data:DataGrid> I bind it to a List< of custom objects: public MainPage() { InitializeComponent(); _Rows = new List<OfferingRowData>(); _Rows.Add(new OfferingRowData() { Trader = "Kameilya Loenstein", Product = "American Consolidated AAA", Price = 24.95, OfferingMade = DateTime.Now }); _Rows.Add(new OfferingRowData() { Trader = "Bill Foobar", Product = "IBM Mid-Atlantic Exotic", Price = 204.90, OfferingMade = DateTime.Now.AddMinutes(-3) }); gridOfferings.ItemsSource = _Rows; } When it shows up on the page, the column headers appear, but none of the data does. What am I doing wrong?

  • How to simplify this code or a better design?

    - by Tattat
    I am developing a game, the game have different mode. Easy, Normal, and Difficult. So, I'm thinking about how to store the game mode. My first idea is using number to represent the difficulty. Easy = 0 Normal = 1 Difficult = 2 So, my code will have something like this: switch(gameMode){ case 0: //easy break; case 1: //normal break; case 3: //difficult break; } But I think it have some problems, if I add a new mode, for example, "Extreme", I need to add case 4... ... it seems not a gd design. So, I am thinking making a gameMode object, and different gameMode is sub class of the super class gameMode. The gameMode object is something like this: class GameMode{ int maxEnemyNumber; int maxWeaponNumber; public static GameMode init(){ GameMode gm = GameMode(); gm.maxEnemyNumber = 0; gm.maxWeaponNumber = 0; return gm; } } class EasyMode extends GameMode{ public static GameMode init(){ GameMode gm = super.init(); gm.maxEnemyNumber = 10; gm.maxWeaponNumber = 100; return gm; } } class NormalMode extends GameMode{ public static GameMode init(){ GameMode gm = super.init(); gm.maxEnemyNumber = 20; gm.maxWeaponNumber = 80; return gm; } } But I think it seems too "bulky" to create an object to store gameMode, my "gameMode" only store different variables for game settings.... Is that any simple way to store data only instead of making an Object? thz u.

  • accessing widgets inside a GWT element

    - by flyingcrab
    I want to access the text elements inside this textbox in GWT from the main method (where I call it like this) DialogBox aBox = newCandidatePop.buildNewElecPopup(); aBox.center(); aBox.getWidget(); MiscUiTools.newCandidateHandler(aBox.firstName, aBox.surName); in newCandidateHandler i want to attach a click handler to the two text boxes However, the above doesnt quite work - I cant get access to the aBox.firstName elements because they are static methods -- I am wondering what is best practice, how would you code something like this up? static TextBox firstName = new TextBox(); static TextBox surName = new TextBox(); static DialogBox box; // public newCandidatePop() { // box = buildNewElecPopup(); // } static public DialogBox buildNewElecPopup() { DialogBox box = new DialogBox(); box.setAutoHideEnabled(true); box.setText("Add a New Candidate"); box.setAnimationEnabled(true); box.setGlassEnabled(true); Grid dialogGrid = new Grid(2, 3); dialogGrid.setPixelSize(250 , 125); dialogGrid.setCellPadding(10); dialogGrid.setWidget(0, 0, new HTML("<strong>First Name</strong>")); dialogGrid.setWidget(0, 1, firstName); dialogGrid.setWidget(1, 0, new HTML("<strong>Surname</strong>")); dialogGrid.setWidget(1, 1, surName); box.add(dialogGrid); return box; }
