  • android: using listpreference and retrieving key string...

    - by Allan
    I have a settings menu that pops up and in it is a listpreference type menu. It is associated with a settings.xml file where there are 'array-strings' within it. It all works good but I don't know how to retrieve the users preference. As an example, let's say the user picks a color (red, green, or blue). The list that I've made within my 'array-strings' contain the text red, green, and blue. Within my code, I would like to do something if the user has choosen red, something else if they choose blue, etc., etc. Would I use a 'case' statement or an 'if' statement? And most importantly, how would I retrieve the users preference - the key? (am I checking for a boolean?) Help would be appreciated...thank you...

  • How do I make matlab legends match the colour of the graphs?

    - by Alex Gosselin
    Here is the code I used: x = linspace(0,2); e = exp(1); lin = e; quad = e-e.*x.*x/2; cub = e-e.*x.*x/2; quart = e-e.*x.*x/2+e.*x.*x.*x.*x/24; act = e.^cos(x); mplot = plot(x,act,x,lin,x,quad,x,cub,x,quart); legend('actual','linear','quadratic','cubic','quartic') This produces a legend matching the right colors to actual and linear, then after that it seems to skip over red on the graph, but not on the legend, i.e. the legend says quadratic should be red, but the graph shows it as green, the legend says cubic should be green, but the graph shows it as purple etc. Any help is appreciated.

  • Subnav "active" when it shouldn't be.

    - by wilwaldon
    http://wilwaldon.com/itsbroken/templateleftnav.php As you can see on the left navigation the link for Template 01 is highlighted green. The link underneath is also highlighted green. I think the problem lies with the initial LI controlling the ul underneath somehow. I need to keep the xhtml formatted exactly how it is right now and only change the CSS to fix this problem. I'd appreciate any help you may be able to point me in the right direction, I'm pretty stuck at this point. Thank you in advance!

  • Random value from Flags enum

    - by Chris Porter
    Say I have a function that accepts an enum decorated with the Flags attribute. If the value of the enum is a combination of more than one of the enum elements how can I extract one of those elements at random? I have the following but it seems there must be a better way. [Flags] enum Colours { Blue = 1, Red = 2, Green = 4 } public static void Main() { var options = Colours.Blue | Colours.Red | Colours.Green; var opts = options.ToString().Split(','); var rand = new Random(); var selected = opts[rand.Next(opts.Length)].Trim(); var myEnum = Enum.Parse(typeof(Colours), selected); Console.WriteLine(myEnum); Console.ReadLine(); }

  • Doing permutation of different arrays in perl

    - by nubie2
    Hello! I want to do permutation in perl. For example I have three arrays. ["big", "tiny", "small"] and then I have ["red", "yellow", "green"] and also ["apple", "pear", "banana"]. How do I get: ["big", "red", "apple"] ["big", "red", "pear"] ..etc.. ["small", "green", "banana"] I understand this is called permutation. But I am not sure how to do it. Also I don't know how many arrays I can have. There may be three or four, so I don't want to do nested loop.

  • Graph databases and Php

    - by stagas
    I want to use a graph database using php. Can you point out some resources on where to get started? Is there any example code / tutorial out there? Or are there any other methods of storing data that relate to each other in totally random/abstract situations? Very abstract example of the relations needed: John relates to Mary, both relate to School, John is Tall, Mary is Short, John has Blue Eyes, Mary has Green Eyes, query I want is which people are related to 'Short people that have Green Eyes and go to School' - answer John It is possible in MySQL but it would require a fixed set of attributes/columns for each item and a complex non-flexible query, instead I need every attribute to be an item by itself and instead of 'belonging' to something, to be 'related' to something.

  • Getting Data From Webpages?

    - by fuzzygoat
    When looking to get data from a web page whats the recommended method if the page does not provide a structured data feed? Am I right in thinking that its just a case of doing an NSURLRequest and then hacking what you need out of the responseData(NSData*)? I am not too concerned about the implementation in Xcode, I am more curious about actually collecting the data, before I start coding a "hunt & peck" through a list of data. gary

  • Getting filtered results with subquery

    - by josepv
    I have a table with something like the following: ID Name Color 1 Bob Blue 2 John Yellow 1 Bob Green 3 Sara Red 3 Sara Green What I would like to do is return a filtered list of results whereby the following data is returned: ID Name Color 1 Bob Blue 2 John Yellow 3 Sara Red i.e. I would like to return 1 row per user. (I do not mind which row is returned for the particular user - I just need that the [ID] is unique.) I have something already that works but is really slow where I create a temp table adding all the ID's and then using a "OUTER APPLY" selecting the top 1 from the same table, i.e. CREATE TABLE #tb ( [ID] [int] ) INSERT INTO #tb select distinct [ID] from MyTable select T1.[ID], T2.[Name], T2.Color from #tb T1 OUTER APPLY ( SELECT TOP 1 * FROM MyTable T2 WHERE T2.[ID] = T1.[ID] ) AS V2 DROP TABLE #tb Can somebody suggest how I may improve it? Thanks

  • No colors when using autospec

    - by kfitzpatrick
    When I'm using autospec to test a non-Rails Ruby project, I always have trouble getting my tests to show up red or green. When I run a regular 'spec spec/ --color' command I get normal red/green responses. I've tried putting all sorts of commands in the .autotest file and I can't get that to work. Also, in my Rails projects, I don't get this problem. Note: I do have the ZenTest(4.2.1) and redgreen (1.2.2) gems installed. I'm currently trying to get it working with this project: http://github.com/coreyhaines/kata-number-to-led

  • ViewController init?

    - by fuzzygoat
    I have just noticed that my ViewController does not call init (See below) when it starts up. -(id)init { self = [super init]; if(self) { NSLog(@"_init: %@", [self class]); otherStuff... } return self; } Is there a reason for this, or is it replaced by viewDidLoad -(void)viewDidLoad { otherStuff .. [super viewDidLoad]; } cheers gary

  • filtering for multiple values on one column. All values must exist, else - return zero

    - by Andrew
    Hello All, I would like to filter one column in a table for couple values and show results only if all those values are there. If one or more is missing, then return zero results. example table +----+--------+----------+ | id | Fruit | Color | +----+--------+----------+ | 1 | apple | red | | 2 | mango | yellow | | 3 | banana | yellow | +----+--------+----------+ example "wrong" code: (this must return 3 rows) select Fruit FROM table WHERE Color = red AND Color = yellow but select Fruit FROM table WHERE Color = red AND Color = green must return 0 rows. (If i use select Fruit FROM table WHERE Color = red OR Color = green i get 1 row which is not what i need) I am using PHP with form where user checks different checkboxes that represent different values of the same column. So when he selects multiple checkboxes, all those values should be in the result set, otherwise no result should be given. Thank you, Andrew

  • Latex change color of intext citing with hyperref package and natbib

    - by Thomas
    I am using the natbib and hyperref package in conjunction with my latex document. I would like to change to the color of my hyppereferenced citations (the box around the citation) from the ugly baseline green to a more muted (violet or navy blue). However, in using the suggested code to do this, I can not get the citation link colors to change. My code is as follows \usepackage[usenames,dvipsnames]{color} \usepackage[round]{natbib} \usepackage[hyperfootnotes=false]{hyperref} \usepackage[hyperfootnotes=false]{hyperref} \hypersetup{ colorlinks=false, citecolor=Violet, linkcolor=Red, urlcolor=Blue} \begin{document} \bibliographystyle{apsr} \bibliography{exp_final} \end{document} However, when I compile (I compiled multiple times to make sure) this my pdf file looks the same as if I had excluded the formatting in the hypersetup (still the same ugly green). I would also like to box the footnote citations as well. Any ideas or help would be much appreciated. Thanks, Thomas

  • 3ds collada UV mapping problem in Papervision

    - by MonsieurOreilles
    Hi everyone, as I briefly explained in the title, my prblem concerns texturing a collada export in papervision. Basically I was exporting collada models from Cinema 4d with its uv map. I was able to see everything, but the texture was not displaying properly (hidden polygons). So I decided to try with 3dsMax. I used the same code to display the texture : var materials:MaterialsList = new MaterialsList(); var torusMaterial:BitmapFileMaterial = new BitmapFileMaterial("model/tex.png"); torusMaterial.precise = true; materials.addMaterial(torusMaterial, "ID1"); Again, I can see every elements, but this time my model uses only one pixel of my texture. So if I use a red texture and if I color only the pixel at the left bottom corner in green, all my model will be green. Any advice about how to properly wrap the texture around a 3ds export model ? Thank you.

The code I'm working with is like this: $('#main .green-tabs a').live("click",function(event){ $('.green-tabs a').removeClass('active'); $(this).addClass('active'); event.preventDefault(); var that = this; return LolPage(event,that);});

  • CSS button not styling

    - by o-logn
    Hey, I must be missing something obvious, but can someone explain what I'm doing wrong with my CSS? I would like all buttons to have a certain format, except a few. I was expecting to use CssClass in order to override the few that should be different, but they all seem to use the standard one. My CSS: .btn { border:none; background-color:red; } input[type="submit"] { border: 2px solid black; background-color:green; } All the buttons take the second value (green background, with a border). However, I have this button: <asp:Button ID="btnAdd" CssClass="btn" runat="server" Text="Add" /> I was expecting this to have no border, and a red background, but it's the same as every other button. Any ideas what I'm doing wrong? Thanks
