  • Shake to open view modally

    - by Vivas
    Hi, I have my 'shake' working fine (using motionEnded), based off of Apple's GLPaint code. When the user shakes the device (running 3.0 and up) I want to open a view controller modally using presentModalViewController. In my appdelegate I have the notification (as per the GLPaint sample code): [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(shakeToOpenHiddenScreen) name:@"shake" object:nil]; In my shakeToOpenHiddenScreen I just want to open view 'x' modally but I don't think that my appdelegate will respond to presentModalViewController. Is there a way around this?

  • Question about design (inheritance, polymorphism)

    - by Dan
    Hi, I have a question about a problem I'm struggling with. Hope you can bear with me. Imagine I have an Object class representing the base class of a hierarchy of physical objects. Later I inherit from it to create an Object1D, Object2D and Object3D classes. Each of these derived classes will have some specific methods and attributes. For example, the 3d object might have functionality to download a 3d model to be used by a renderer. So I'd have something like this: class Object {}; class Object1D : public Object { Point mPos; }; class Object2D : public Object { ... }; class Object3D : public Object { Model mModel; }; Now I'd have a separate class called Renderer, which simply takes an Object as argument and well, renders it :-) In a similar way, I'd like to support different kinds of renderers. For instance, I could have a default one that every object could rely on, and then provide other specific renderers for some kind of objects: class Renderer {}; // Default one class Renderer3D : public Renderer {}; And here comes my problem. A renderer class needs to get an Object as an argument, for example in the constructor in order to retrieve whatever data it needs to render the object. So far so good. But a Renderer3D would need to get an Object3D argument, in order to get not only the basic attributes but also the specific attributes of a 3d object. Constructors would look like this: CRenderer(Object& object); CRenderer3D(Object3D& object); Now how do I specify this in a generic way? Or better yet, is there a better way to design this? I know I could rely on RTTI or similar but I'd like to avoid this if possible as I feel there is probably a better way to deal with this. Thanks in advance!

  • NewBie Question, jQuery: How can we implement if...else logic and call function

    - by Rachel
    I am new to jQuery and so don't mind this question if it sounds stupid but here is something that I am trying to do : I have 3 functions like: AddToCart Function which adds item to the shopping cart: //offer_id is the offer which we are trying to add to cart. addToCart: function(offer_id) { this.submit({action: 'add', 'offer_id': offer_id}, {'app_server_url': this.app_server_url}); }, RemoveFromCart which removes data from the cart //target is link clicked and event is the click event. removeFromCart: function(target, event) { this.uniqueElmt('cart_table').find('.sb_item_remove').unbind('click'); var offer_id = $(target).parent().find('.offer_id').html(); this.submit({action: 'remove', 'offer_id': offer_id, 'next_action': this.config.current_action}, {'app_server_url': this.app_server_url}); }, Get the current state of the cart //return string which represents current state of cart. getCartItems: function() { return this.contents; } Now I am trying to do 3 things: if there is no content in cart and addToCart is called than some action, so basically here we need to check the current state of cart and that is obtained by calling getCartItems and if it is Null and than if addToCart is called than we perform some action if there is content in the cart and addToCart is called than some action,so basically here we need to check the current state of cart and that is obtained by calling getCartItems and check if it is Null or not and than if addToCart is called than we perform some action if we had some content in the cart. if there is content in the cart and removeFromCart is called some action, so basically here we need to check the current state of cart and that is obtained by calling getCartItems and if it is not Null and if removeFromCart is called than we perform some action Pseudocode of what I am trying to do: if there is no content in cart and addToCart is called than $(document).track( { 'module' : 'Omniture', 'event' : 'instant', 'args' : { 'linkTrackVars' : 'products,events', 'linkTrackEvents' : 'scAdd,scOpen', 'linkType' : 'o', 'linkName' : 'Cart : First Product Added' // could be blank, but can include event name as added feature 'svalues' : { 'products' : ';OFFERID1[,;OFFERID2]', 'events' : 'scAdd,scOpen', }, } 'defer' : '0' } ); if there is content in the cart and addToCart is called than $(document).track( { 'module' : 'Omniture', 'event' : 'instant', 'args' : { 'linkTrackVars' : 'products,events', 'linkTrackEvents' : 'scAdd', 'linkType' : 'o', 'linkName' : 'Cart : Product Added' // could be blank, but can include event name as added feature 'svalues' : { 'products' : ';OFFERID1[,;OFFERID2]', 'events' : 'scAdd', }, }, 'defer' : '0' } ); if there is content in the cart and removeFromCart is called $(document).track( { 'module' : 'Omniture', 'event' : 'instant', 'args' : { 'linkTrackVars' : 'products,events', 'linkTrackEvents' : 'scRemove', 'linkType' : 'o', 'linkName' : 'Cart : Product Removed' // could be blank, but can include event name as added feature 'svalues' : { 'products' : ';OFFERID1[,;OFFERID2]', 'events' : 'scRemove', }, } 'defer' : '0' } ); My basic concern is that am complete newbie to jQuery and JavaScript and so am not sure how can I implement if...else logic and how can I call a funtion using jQuery/JavaScript.

  • Question about DBD::CSB Statement-Functions

    - by sid_com
    From the SQL::Statement::Functions documentation: Function syntax When using SQL::Statement/SQL::Parser directly to parse SQL, functions (either built-in or user-defined) may occur anywhere in a SQL statement that values, column names, table names, or predicates may occur. When using the modules through a DBD or in any other context in which the SQL is both parsed and executed, functions can occur in the same places except that they can not occur in the column selection clause of a SELECT statement that contains a FROM clause. # valid for both parsing and executing SELECT MyFunc(args); SELECT * FROM MyFunc(args); SELECT * FROM x WHERE MyFuncs(args); SELECT * FROM x WHERE y < MyFuncs(args); # valid only for parsing (won't work from a DBD) SELECT MyFunc(args) FROM x WHERE y; Reading this I would expect that the first SELECT-statement of my example shouldn't work and the second should but it is quite the contrary. #!/usr/bin/env perl use warnings; use strict; use 5.010; use DBI; open my $fh, '>', 'test.csv' or die $!; say $fh "id,name"; say $fh "1,Brown"; say $fh "2,Smith"; say $fh "7,Smith"; say $fh "8,Green"; close $fh; my $dbh = DBI->connect ( 'dbi:CSV:', undef, undef, { RaiseError => 1, f_ext => '.csv', }); my $table = 'test'; say "\nSELECT 1"; my $sth = $dbh->prepare ( "SELECT MAX( id ) FROM $table WHERE name LIKE 'Smith'" ); $sth->execute (); $sth->dump_results(); say "\nSELECT 2"; $sth = $dbh->prepare ( "SELECT * FROM $table WHERE id = MAX( id )" ); $sth->execute (); $sth->dump_results(); outputs: SELECT 1 '7' 1 rows SELECT 2 Unknown function 'MAX' at /usr/lib/perl5/site_perl/5.10.0/SQL/Parser.pm line 2893.

  • JavaFX - question regarding binding button's disabled state

    - by jamiebarrow
    I'm trying to create a dummy application that maintains a list of tasks. For now, all I'm trying to do is add to the list. I enter a task name in a text box, click on the add task button, and expect the list to be updated with the new item and the task name input to be cleared. I only want to be able to add tasks if the task name is not empty. The below code is my implementation, but I have a question regarding the binding. I'm binding the textbox's text variable to a string in my view model, and the button's disable variable to a boolean in my view model. I have a trigger to update the disabled state when the task name changes. When the binding of the task name happens the boolean is updated accordingly, but the button still appears disabled. But then when I mouse over the button, it becomes enabled. I believe this is due to JavaFX 1.3's binding being lazy - only updates the bound variable when it is read. Also, when I've added the task, I clear the task name in the model, but the textbox's text doesn't change - even though I'm using bind with inverse. Is there a way to make the textbox's text and the button's disabled state update automatically via the binding as I was expecting? Thanks, James AddTaskViewModel.fx: package jamiebarrow; import java.lang.System; public class AddTaskViewModel { function logChange(prop:String,oldValue,newValue):Void { println("{System.currentTimeMillis()} : {prop} [{oldValue}] to [{newValue}] "); } public var newTaskName: String on replace old { logChange("newTaskName",old,newTaskName); isAddTaskDisabled = (newTaskName == null or newTaskName.trim().length() == 0); }; public var isAddTaskDisabled: Boolean on replace old { logChange("isAddTaskDisabled",old,isAddTaskDisabled); }; public var taskItems = [] on replace old { logChange("taskItems",old,taskItems); }; public function addTask() { insert newTaskName into taskItems; newTaskName = ""; } } Main.fx: package jamiebarrow; import javafx.scene.control.Button; import javafx.scene.control.TextBox; import javafx.scene.control.ListView; import javafx.scene.Scene; import javafx.scene.layout.VBox; import javafx.stage.Stage; import javafx.scene.layout.HBox; def viewModel = AddTaskViewModel{}; var txtName: TextBox = TextBox { text: bind viewModel.newTaskName with inverse onKeyTyped: onKeyTyped }; function onKeyTyped(event): Void { txtName.commit(); // ensures model is updated cmdAddTask.disable = viewModel.isAddTaskDisabled;// the binding only occurs lazily, so this is needed } var cmdAddTask = Button { text: "Add" disable: bind viewModel.isAddTaskDisabled with inverse action: onAddTask }; function onAddTask(): Void { viewModel.addTask(); } var lstTasks = ListView { items: bind viewModel.taskItems with inverse }; Stage { scene: Scene { content: [ VBox { content: [ HBox { content: [ txtName, cmdAddTask ] }, lstTasks ] } ] } }

  • Automatically open files given as command line arguments in Python

    - by mk
    I have a lot of Perl scripts that looks something like the following. What it does is that it will automatically open any file given as a command line argument and in this case print the content of that file. If no file is given it will instead read from standard input. while ( <> ) { print $_; } Is there a way to do something similar in Python without having to explicitly open each file?

  • Quick question regarding this issue, Why doesnt it print out the second value(converted second value

    - by sil3nt
    Quick question, What have I done wrong here. The purpose of this code is to get the input into a string, the input being "12 34", with a space in between the "12" and "32" and to convert and print the two separate numbers from an integer variable known as number. Why doesn't the second call to the function copyTemp, not produce the value 34?. I have an index_counter variable which keeps track of the string index and its meant to skip the 'space' character?? what have i done wrong? thanks. #include <stdio.h> #include <string.h> int index_counter = 0; int number; void copyTemp(char *expr,char *temp); int main(){ char exprstn[80]; //as global? char tempstr[80]; gets(exprstn); copyTemp(exprstn,tempstr); printf("Expression: %s\n",exprstn); printf("Temporary: %s\n",tempstr); printf("number is: %d\n",number); copyTemp(exprstn,tempstr); //second call produces same output shouldnt it now produce 34 in the variable number? printf("Expression: %s\n",exprstn); printf("Temporary: %s\n",tempstr); printf("number is: %d\n",number); return 0; } void copyTemp(char *expr,char *temp){ int i; for(i = index_counter; expr[i] != '\0'; i++){ if (expr[i] == '0'){ temp[i] = expr[i]; } if (expr[i] == '1'){ temp[i] = expr[i]; } if (expr[i] == '2'){ temp[i] = expr[i]; } if (expr[i] == '3'){ temp[i] = expr[i]; } if (expr[i] == '4'){ temp[i] = expr[i]; } if (expr[i] == '5'){ temp[i] = expr[i]; } if (expr[i] == '6'){ temp[i] = expr[i]; } if (expr[i] == '7'){ temp[i] = expr[i]; } if (expr[i] == '8'){ temp[i] = expr[i]; } if (expr[i] == '9'){ temp[i] = expr[i]; } if (expr[i] == ' '){ temp[i] = '\0'; sscanf(temp,"%d",&number); index_counter = i+1; //skips? } } // is this included here? temp[i] = '\0'; }

  • JQuery selfbuild plugin question - default value is overwritten.

    - by Bruno
    Hi jQuery ninjas. I need your help. I have made a really clean and simple example to illustrate my problem. I have build my own jquery plugin: (function($) { $.fn.setColorTest = function(options) { options = $.extend($.fn.setColorTest.defaults,options); return this.each(function() { $(this).css({ 'color': options.color}); }); } $.fn.setColorTest.defaults = { color: '#000' }; })(jQuery); As you can see I'm setting a default color and making it possible for the user to change it. My problem/question is: I have two paragraphs on the same page where I want to use the default color for the first and a different color for the second paragraph: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Color Test</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $('a#click').click(function() { $('#test1').setColorTest(); }); $('a#click2').click(function() { $('#test2').setColorTest({color: '#fff666'}); }); }); </script> </head> <body> <a id="click">click here</a> <a id="click2">click here2</a> <p id="test1">Test 1</p> <p id="test2">Test 2</p> </body> </html> My problem is that if I click on the second paragraph (p) that overrides the default color and afterwards clicks on the first p it will use the overwritten color and not the default color for the first p. How can I ensure that the first p always will use the default color? I know I can just define the color for the first p as well but that is not an option here $('#test1').setColorTest('color': '#000'); So what to do?

  • Array Sorting Question for News System

    - by lemonpole
    Hello all. I'm currently stuck trying to figure out how to sort my array files. I have a simple news posting system that stores the content in seperate .dat files and then stores them in an array. I numbered the files so that my array can sort them from lowest number to greatest; however, I have run into a small problem. To begin here is some more information on my system so that you can understand it better. The function that gathers my files is: function getNewsList() { $fileList = array(); // Open the actual directory if($handle = opendir(ABSPATH . ADMIN . "data")) { // Read all file from the actual directory while($file = readdir($handle)) { if(!is_dir($file)) { $fileList[] = $file; } } } // Return the array. return $fileList; } On a seperate file is the programming that processes the news post. I didn't post that code for simplicity's sake but I will explain how the files are named. The files are numbered and the part of the post's title is used... for the numbering I get a count of the array and add "1" as an offset. I get the title of the post, encode it to make it file-name-friendly and limit the amount of text so by the end of it all I end up with: // Make the variable that names the file that will contain // the post. $filename = "00{$newnumrows}_{$snipEncode}"; When running print_r on the above function I get: Array ( [0] => 0010_Mira_mi_Soledad.dat [1] => 0011_WOah.dat [2] => 0012_Sinep.dat [3] => 0013_Living_in_Warfa.dat [4] => 0014_Hello.dat [5] => 001_AS.dat [6] => 002_ASASA.dat [7] => 003_SSASAS.dat ... [13] => 009_ASADADASADAFDAF.dat ) And this is how my content is displayed. For some reason according to the array sorting 0010 comes before 001...? Is there a way I can get my array to sort 001 before 0010?

  • Windows Question: RunOnce/Second Boot Issues [closed]

    - by Greg
    Moved to Super User: Windows Question: RunOnce/Second Boot Issues I am attempting to create a Windows XP SP3 image that will run my application on Second Boot. Here is the intended workflow. 1) Run Image Prep Utility (I wrote) on windows to add my runonce entries and clean a few things up. 2) Reboot to ghost, make image file. 3) Package into my ISO and distribute. 4) System will be imaged by user. 5) On first boot, I have about 5 things that run, one of which includes a driver updater (I wrote) for my own specific devices. 6) One of the entries inside of HKCU/../runonce is a reg file, which adds another key to HKLM/../runonce. This is how second boot is acquired. 7) As a result of the driver updater, user is prompted to reboot. 8) My application is then launched from HKLM/../runonce on second boot. This workflow works perfectly, except for a select few legacy systems that contain devices that cause the add hardware wizard to pop up. When the add hardware wizard pops up is when I begin to see problems. It's important to note, that if I manually inspect the registry after the add hardware wizard pops up, it appears as I would expect, with all the first boot scripts having run, and it's sitting in a state I would correctly expect it to be in for a second boot scenario. The problem comes when I click next on the add hardware wizard, it seems to re-run the single entry I've added, and re-executes the runonce scripts. (only one script now as it's already executed and cleared out the initial entries). This causes my application to open as if it were a second boot, only when next is clicked on the add hardware wizard. If I click cancel, and reboot, then it also works as expected. I don't care as much about other solutions, because I could design a system that doesn't fully rely on Microsoft's registry. I simply can't find any information as to WHY this is happening. I believe this is some type of Microsoft issue that's presenting itself as a result of an overstretched image that's expected to support too many legacy platforms, but any help that can be provided would be appreciated. Thanks,

  • Rails has-and-belongs-to-many form question

    - by swilliams
    Sorry for the semi-generic title, but I'm still pretty new at rails and couldn't think of a succinct way to put the question. I have a basic habtm model setup: a Project has many Resources and a Resource can have many Projects. I have the database and models setup properly, and can do everything I need to via the console, but I'm having trouble translating it all into the view. On the show view for the Project, I want to be able to create a Resource and automatically assign it to the current Project. Here's my basic html: <p> <b>Name:</b> <%=h @project.name %> </p> <h2>Equipment</h2> <ul> <% @project.resources.each do |r| %> <li><%=h r.name %></li> <% end %> </ul> <h2>Add A Resource</h2> <% form_for(@project) do |f| %> <%= f.error_messages %> <p> Resource Name:<br /> <%= f.text_field :resources %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> Obviously, that form won't work, but I'm at a loss for what to do next. I've searched around for various examples, but haven't found one for what I'm trying to do here. One thing I've thought of was to change the form to be form_for(Resource.new) and include a hidden input of the @project.id. And then when the resource_controller handles the form, check for that id and go from there. That seems like an ugly kludge though.

  • Just a small problem regarding javscript BOM question

    - by caramel1991
    The question is this: Create a page with a number of links. Then write code that fires on the window onload event, displaying the href of each of the links on the page. And this is my solution <html> <body language="Javascript" onload="displayLink()"> <a href="http://www.google.com/">First link</a> <a href="http://www.yahoo.com/">Second link</a> <a href="http://www.msn.com/">Third link</a> <script type="text/javascript" language="Javascript"> function displayLink() { for(var i = 0;document.links[i];i++) { alert(document.links[i].href); } } </script> </body> </html> This is the answer provided by the book <html> <head> <script language=”JavaScript” type=”text/javascript”> function displayLinks() { var linksCounter; for (linksCounter = 0; linksCounter < document.links.length; linksCounter++) { alert(document.links[linksCounter].href); } } </script> </head> <body onload=”displayLinks()”> <A href=”link0.htm” >Link 0</A> <A href=”link1.htm”>Link 2</A> <A href=”link2.htm”>Link 2</A> </body> </html> Before I get into the javascript tutorial on how to check user browser version or model,I was using the same method as the example,by acessing the length property of the links array for the loop,but after I read through the tutorial,I find out that I can also use this alternative ways,by using the method that the test condition will evalute to true only if the document.links[i] return a valid value,so does my code is written using the valid method??If it's not,any comment regarding how to write a better code??Correct me if I'm wrong,I heard some of the people say "a good code is not evaluate solely on whether it works or not,but in terms of speed,the ability to comprehend the code,and could posssibly let others to understand the code easily".Is is true??
