  • How to create a splash activity , call a second activity via a button, simple data form 5 fields and 2 buttons

    - by Mike
    New to Android need help with one solid build that I can refer to and study for future projects. The first activity is a background image with a button,when clicked the it takes you to the second activity which is a form with 5 data fields and 2 buttons. One button calls an intent to take a picture within the app and one button that submits the data from the form along with the picture to URL. lastly a third activity that says complete thank you. I can make some of this but don't know how to link button or open and merge camera with the app to be sent as a package of data. I suppose I could also hook into GPS acquire location as well as the camera call?

  • How to create an image from array of pixel colors? (Flash, Actionscript 3)

    - by Ole Jak
    I have a Width and Height parametr. I have been given an array of colors in such format: [r, g, b, a, r, g, b, a, r, g, b, a... etc] Data can be acsessed by something like this for(var y = 0; y < height; y++) { for(var x = 0; x < width; x++) { r = data[y*width + x + 0] g = data[y*width + x + 1] b = data[y*width + x + 2] a = data[y*width + x + 3] } } I want to paint that data on some sprite. How to do such thing? BTW: I use Flash Builder for mxml+actionscript coding. So if it is easy for you you can give example using MXML (not todraw on some sprite but on some MXML component).

    - by Robin

  • Simplest way to create a wrapper class around some strings for a WPF DataGrid?

    - by Joel
    I'm building a simple hex editor in C#, and I've decided to use each cell in a DataGrid to display a byte*. I know that DataGrid will take a list and display each object in the list as a row, and each of that object's properties as columns. I want to display rows of 16 bytes each, which will require a wrapper with 16 string properties. While doable, it's not the most elegant solution. Is there an easier way? I've already tried creating a wrapper around a public string array of size 16, but that doesn't seem to work. Thanks *The rational for this is that I can have spaces between each byte without having to strip them all out when I want to save my edited file. Also it seems like it'll be easier to label the rows and columns.

  • Templates --> How to decipher, decide if necessary and create?

    - by ML
    Hi All, I have a few classes in a project that I inherited that are really old, last I knew they compiled with CodeWarrior 8. I am not in XCode 3.2 Here is an example of what I struggle with: template <class registeredObject> typename std::vector<registeredObject>::iterator FxRegistry<registeredObject>::begin(void) { return mRegistryList.begin(); } The errors are: no 'typename std::vector<registeredObject, std::allocator<_CharT> >::iterator FxRegistry<registeredObject>::begin()' member function declared in class 'FxRegistry<registeredObject>' template definition of non-template 'typename std::vector<registeredObject, std::allocator<_CharT> >::iterator FxRegistry<registeredObject>::begin()' How do I decide how to solve these and where do I start looking?

  • How to create a hover effect in a newsletter?

    - by Moak
    I'm creating a newsletter, and i want to have panels that change background-color on mouse over. Seeing as the newsletter wont have a head, I am defining all styles inline. I'm pretty sure most popular mail clients will block JS. So I was wondering if I can define a hover effect in the style attribute. Or is there any other solution to achieve this effect? Peace

  • What is the easiest way to create a clickable grid for a game in C++?

    - by mangoman13
    I haven't used C++ in a while, so I decided to take on a small project to become familiar with it again. I am trying to make a chinese checkers game, but I have no experience with GUI design in C++. Is there a real simple way to just make grid (i.e. bitmap hexagons or something) that when clicked on, will give me the index number of the one I've clicked on? If someone has any examples of how to do this, even with just a 2D grid of squares, that would be helpful. Any help is appreciated, thanks!

  • How to create a project template for Ruby on Rails projects?

    - by wgpubs
    When I build Rails applications I find myself doing the same things over and over again. This includes adding the same gems/plugins, configuration info and custom initializers, rake tasks etc... etc.... This can't be a good thing. So, is there a way to package all this repetitive code into some sort of project template ... so that I can do a "rails myapp" and have everything good to go from there? Btw, running 2.3.5 if that matters :) thanks

  • How do I create a polymorphic model with a collection_select?

    - by muxe
    This are my models: class Speaker < ActiveRecord::Base belongs_to :session, :foreign_key => :session_id, :class_name => :Session belongs_to :speakable, :polymorphic => true end class Session < ActiveRecord::Base has_many :speakers accepts_nested_attributes_for :speakers end class Person < ActiveRecord::Base has_many :speakers, :as => :speakable end class Company < ActiveRecord::Base has_many :speakers, :as => :speakable end What I want to do now is something like this: app/views/sessions/edit.html.erb <% f.fields_for :speakers do |sf| %> <p> <%= sf.label :speaker %><br /> <%= sf.collection_select :speakable, Company.all + Person.all, :id, :full_name %> </p> <% end %> But it is not working because of the polymorphic assignment. How do I approach this problem? EDIT: The Error is: undefined method `base_class' for String:Class with params being: "speaker"=>{"speakable"=>"1063885469", "session_id"=>"1007692731"} The value passed to speakable is the id of the Speaker/Company. Yes, this is the value I specified the collection_select to return, but how can I manage to supply both values (speakable_id and speakable_type) ?

  • How do I create a list of timedeltas in python?

    - by eunhealee
    I've been searching through this website and have seen multiple references to time deltas, but haven't quite found what I'm looking for. Basically, I have a list of messages that are received by a comms server and I want to calcuate the latency time between each message out and in. It looks like this: 161336.934072 - TMsg out: [O] enter order. RefID [123] OrdID [4568] 161336.934159 - TMsg in: [A] accepted. ordID [456] RefNumber [123] Mixed in with these messages are other messages as well, however, I only want to capture the difference between the Out messages and in messages with the same RefID. So far, to sort out from the main log which messages are Tmessages I've been doing this, but it's really inefficient. I don't need to be making new files everytime.: big_file = open('C:/Users/kdalton/Documents/Minicomm.txt', 'r') small_file1 = open('small_file1.txt', 'w') for line in big_file: if 'T' in line: small_file1.write(line) big_file.close() small_file1.close() How do I calculate the time deltas between the two messages and sort out these messages from the main log?

  • Using Zend_Navigation, how do I create image-based navigation?

    - by SimpleCoder
    (I'm assuming my navigation should be in a layout script.) I have a navigation bar composed of rollover images. The image corresponding to the page that is active should be a different color, though. I do this by changing the image. My question is, where and how should I implement this using Zend_Navigation? Details: The menu itself is just a stack of divs that are floated to the left within a container. Each div has a background image. Thank you for your help,

  • How to take a NSString such as, "0+1+2", get the sum of those and create new string. Obj-C

    - by Ace Legend
    Alright. My app has a text field and next to it are two buttons (Plus button and Equals button). When you press the "Plus" button, it takes the text inside of the textField and adds a "+" to it. Code below: - (IBAction)plusButtonPressed:(id)sender { NSString *plusString = @"+"; NSString *inputString = carbsField.text; NSString *outputString = [NSString stringWithFormat:@"%@%@",inputString,plusString]; NSLog(@"%@",outputString); [carbsField setText:outputString]; } I will eventually make that more intelligent so that I can't put two pluses or whatever. Anyway, then I want the equal button to take whatever is in the textField, which should look something like: "23+54+2.2" and get the sum of those values. I believe I know how to take an Integer and make it a String, but I want to verify it: int *value = 56; NSString *string = @"%d",value; Well, if anyone can show me how to do this, I would be very appreciative. Thanks. EDIT At the moment, I have not tried anything. This is because I do not know where to start. I have an idea of what to do, but I do not know how to execute it. I believe I need to get all characters before a "+" convert them into int and then get the sum of some array of those values.

  • How to pass an integer to create new variable name?

    - by Joe
    I have 50 svg animations named animation0, animation1, animation2 etc. and I want to load them when the integer 0 to 49 is passed to this function: function loadAnimation(value){ var whichswiffy = "animation" + value; var stage = new swiffy.Stage(document.getElementById('swiffycontainer'), whichswiffy); stage.start(); } It doesn't work at the moment, maybe it's passing 'whichswiffy' rather than 'animation10'? Any ideas?

  • Can I create a two-column layout that fluidly adapts to narrow windows?

    - by Brant Bobby
    I'm trying to design a page that has two columns of content, div#left and div#right. (I know these aren't proper semantic identifiers, but it makes explaining easier) The widths of both columns are fixed. Desired result - Wide viewport When the viewport is too narrow to display both side-by-side, I want #right to be stacked on top of #left, like this: Desired result - narrow viewport My first thought was simply to apply float: left to #left and float: right to #right, but that makes #right attach itself to the right side of the window (which is the proper behavior for float, after all), leaving an empty space. This also leaves a big gap between the columns when the browser window is really wide. Wrong - div#right is not flush with the left side of the viewport Wrong - div#right is not on top of div#left Applying float: left to both divs would result in the wrong one moving to the bottom when the window was too small. I could probably do this with media queries, but IE doesn't support those until version 9. The source order is unimportant, but I need something that works in IE7 minimum. Is this possible to do without resorting to Javascript?
