  • UITableView custom popping

    - by ckrames1234
    Okay, I made an app that has a list of items as a main view, and when you select an item it pushes a detail view controller. In this detail view controller you can switch between items. I want to be able to push a view, scroll a few items, and pop the view as if the current item was initially selected. I want to push a view, and then when i pop it, i want it to look like a different view was initially pushed. Here's a rough image, because its hard to explain in writing: http://96.248.81.29:83/misc/PushPopSituation.png (Thats a fixed IP, its not going anywhere) If anyone knows how I could do something like this, it would be a great help to me.

  • String length difference between ruby 1.8 and 1.9

    - by Raghu
    I have a website thats running on ruby 1.8.7 . I have a validation on an incoming post that checks to make sure that we allow upto max of 12000 characters. The spaces are counted as characters and tab and carriage returns are stripped off before the post is subjected to the validation. Here is the post that is subjected to validation http://pastie.org/5047582 In ruby 1.9 the string length shows up as 11909 which is correct. But when I check the length on ruby 1.8.7 is turns out to be 12044. I used codepad.org to run this ruby code which gives me http://codepad.org/OxgSuKGZ ( which outputs the length as 12044 which is wrong) but when i run this same code in the console at codeacademy.org the string length is 11909. Can anybody explain me why this is happening ??? Thanks

  • What are some good web development blogs?

    - by Poita_
    I'm just getting into some basic web development (just a personal homepage for now, but I have plans for bigger things once I know the basics). I find that blogs can be quite helpful in getting into the mindset of a particular activity, so I was wondering if anyone knew some good ones. I'm particularly looking for education blogs i.e. ones that actually explain how to do things instead of just making commentary on them. If the blog is specific to LAMP, or any one (or more) of those things (Linux, Apache, MySQL, PHP) then that's a bonus. Thanks in advance.

  • SmartGWT Canvas width problem

    - by Doug
    I am having problems with showing my entire SmartGWT Canvas on my initial page. I've stripped everything out and am left with an extremely basic EntryPoint to illustrate my issue. When I just create a Canvas and add it to the root panel, I get a horizontal scrollbar in my browser. Can anyone explain why and what I can do to have the Canvas sized to the width of the window? Thanks in advance. public class TestModule implements EntryPoint { protected Canvas view = null; /** * This is the entry point method. */ public void onModuleLoad() { view = new Canvas(); view.setWidth100(); view.setHeight100(); view.setShowEdges( true ); RootPanel.get().add( view ); } }

  • ODBC Connection String Problem

    - by Brett
    Hi there, I am having major trouble connecting to my database via ODBC. The db is local (but I have a mirror on a virtual machine), so I am trying to use the connectionstring: Dsn=MonetDB;host=TARBELL where TARBELL is the name of my computer. However, it doesn't connect. BUT, this string does: Dsn=MonetDB;host=localhost as does Dsn=MonetDB Can anyone explain this? I am at a complete loss. I have taken down my firewalls (at least until I get this figured out), so that can't be the problem. I eventually want to change the TARBELL to the mirrored virtual machine running another instance of the database. Many thanks, Brett

  • Good book for THINKING in terms of algorithms?

    - by chrisgoyal
    Before you mark this is a duplicate, let me explain why this is different. Most of the books on algorithms are more of a reference. You basically have a list of algorithms at your disposal. But what happens when you need to create a new algorithm for something? These books don't teach how to think in terms of algorithms. So I'm looking for books that will teach me the thinking-process of creating algorithms. Any good suggestions?

  • Android 2.2 deprecates restartPackage but adds another headache...

    - by mob1lejunkie
    Android 2.2 release notes have just been released. ActivityManager.restartPackage method has been deprecated and the description is: the previous behavior here is no longer available to applications because it allows them to break other applications by removing their alarms, stopping their services, etc. Instead 2.2 has given another tool for pesky "task killer" apps by introducing new ActivityManager.killBackgroundProcesses method. More Info Can someone explain whether ActivityManager.killBackgroundProcesses will kill our scheduled alarms? If so, deprecating ActivityManager.restartPackage was pointless as "task killer" will now abuse ActivityManager.killBackgroundProcesses.

  • Playing a .wav sound file in JPanel/JFrame using Java (Swing)

    - by JavaIceCream
    I need some code example on how I would use a filepath from a harddrive location to then play a .wav sound file when opened in swing GUI. I don't need it to show a play button, or pause or stop. I just want it to play when I select the 'Sound' option from my 'Files' in my window (I know how to do that already, no need to explain that). So basically, just how to play a .wav sound file from a filepath (i.e. c:/cake/thereisnone.wav) inside of a JFrame. And how can I easily apply methods to that sound file afterwards. Also, if anyone knows how to apply methods on a BufferedImage in a JFrame, that would be helpful too. Thank you very much everyone!

  • Initializing a Global Struct in C

    - by Scott
    What is the best way to accomplish the following in C? #include <stdio.h> struct A { int x; }; struct A createA(int x) { struct A a; a.x = x; return a; } struct A a = createA(42); int main(int argc, char** argv) { printf("%d\n", a.x); return 0; } When I try to compile the above code, the compiler reports the following error: "initializer element is not constant" The bad line is this one: struct A a = createA(42); Can someone explain what is wrong? I'm not very experienced in C. Thanks!

  • WinForms - Localization - UI controls positions different in additional Culture

    - by binball
    Hi, I did my UI settings.Original language is English. After that I set Localizable property to True. Copied original resx file to frmMain.de-De.resx (for example). Translated all strings. Everything works. But now I would like to change positions of controls. After that changes are visible only for original/primary Culture (En). When I change Culture to de-De then UI controls are on the "old positions"(?!) Is this normal behaviour? :O I'm unable to change controls positions on my form after localization? Can someone explain me this and give some best solution. I really have to change UI design but I don't want to manual copy all translated strings again. If my description is not clear then I can post source code, just please let me know. I use VS 2008. Greetz!

  • Vim: how to undo a regex with a new regex?

    - by Victor Tihomirov
    my I have here a text that has been encrypted in Vi this way: 1,$s/\(.\)\1/&&/g 1,$s/\(.\)\(.\)\2\2\2/\2\2\2\1\2/g 1,$s/\(.\)\(.\)\(.\)\(.\)/\3\1\4\2/g 1,$s/\(...\)\(...\)/\2\1/g The task is to write a new regex for each regex in order to undo the the changes, so-called decrypting of the text. I figured out how to undo the last 2 changes: :1,$s/\(...\)\(...\)/\2\1/g :1,$s/\(.\)\(.\)\(.\)\(.\)/\2\4\1\3/g I'd like you to explain me what do the first two regex do. What does \1 or \2\2\2 mean before the forward slash? I assume that after the slash they change place (but wouldn't it be enough to just write \2\1 instead of \2\2\2\1\2(what does it mean?)? I just don't get it). And what does & or && mean? Thank you

  • C# - Pass by value & Pass by Reference

    - by Lijo
    Hi Team, Could you please explain the following behavior of C# Class. I expect the classResult as "Class Lijo"; but actual value is “Changed”. We’re making a copy of the reference. Though the copy is pointing to the same address, the method receiving the argument cannot change original. Still why the value gets changed ? public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Person p = new Person(); p.Name = "Class Lijo"; Utilityclass.TestMethod(p); string classResult = p.Name; Response.Write(classResult); } } public class Utilityclass { public static void TestMethod(Person k) { k.Name = "Changed"; } } public class Person { private string name; public string Name { get { return name; } set { name = value; } } } Thanks Lijo

  • How to use a SOAP API in ASP.NET?

    - by jonhobbs
    Hi, I've trying to use the API for CapsuleCRM... http://capsulecrm.com/help/page/api_gettingstarted I've been reading some articles on SOAP in asp.net and I just don't get it. Most of them seem to be ablut creating a web service, not using it and none of them seem to explain how to use basic HTTP authentication. I have got as far as constructing the XML i want to send to the API but I could really do with seeing some example code which makes an http call using http authentication to a SOAP API. Maybe I'm just searching for the wrong thing but I've drawn a blank so far. Can anybody show me how? Jon

  • Simple python oo issue

    - by Alex K
    Hello, Have a look a this simple example. I don't quite understand why o1 prints "Hello Alex" twice. I would think that because of the default self.a is always reset to the empty list. Could someone explain to me what's the rationale here? Thank you so much. class A(object): def __init__(self, a=[]): self.a = a o = A() o.a.append('Hello') o.a.append('Alex') print ' '.join(o.a) # >> prints Hello Alex o1 = A() o1.a.append('Hello') o1.a.append('Alex') print ' '.join(o1.a) # >> prints Hello Alex Hello Alex

  • Java enums: Gathering info from another enums

    - by Samuel Carrijo
    I made a similar question a few days ago, but now I have new requirements, and new challenges =). As usual, I'm using the animal enums for didactic purposes, once I don't want to explain domain-specific stuff I have a basic enum of animals, which is used by the whole zoo (I can add stuff to it, but must keep compatibility): public enum Animal { DOG, ELEPHANT, WHALE, SHRIMP, BIRD, GIRAFFE; } I need to categorize them in a few, non-related categories, like gray animals (whale (my whale is gray) and elephant), small animals (bird, shrimp and dog), sea animals (whale and shrimp). I could, as suggested in my previous questions, add a lot of booleans, like isGray, isSmall and isFromSea, but I'd like an approach where I could keep this somewhere else (so my enum doesn't need to know much). Something like: public enum Animal { DOG, ELEPHANT, WHALE, SHRIMP, BIRD, GIRAFFE; public boolean isGray() { // What comes here? } } Somewhere else public enum GrayAnimal { WHALE, ELEPHANT; } How is this possible? Am I requesting too much from Java?

  • What is the purpose of both target API and minSDK

    - by Scott Ferguson
    Can somebody explain to me the difference between the project target and the minimum SDK? I want my app to run on Donut devices, and the APK I built with a target of 7 worked just fine. When I set an explicit minimum SDK in the Android manifest of 4 (1.6) the compiler bitched at me that the target exceeded the minimum. I reset the target to 4 only to see what would happen, and now I've got compiler errors. An example is the START_NOT_STICKY constant in android.app.Service. It doesn't exist in API level 4, but does exist in API level 7. This is also the case with Service.onStartCommand(). In API level 7 you need to explicity override this method, whereas in API level 4 you don't. So why does the app work in 1.6 despite all this? How could 1.6 know how to use SERVICE_NOT_STICKY when the associated API level doesn't know about it?

  • Setting freemarker template from classpath

    - by wuntee
    I have a web application that I need to manually obtain a Freemarker template - the template is obtained via a class in a library project, but the actual tpl file is contained in the web application classpath. So, there are 2 projects, one 'taac-backend-api' and another 'taac-web'; taac-backend-api has the code to grab the template, and process it, but taac-web is where the template is stores (specifically in: WEB-INF/classes/email/vendor.tpl) - I have tried everything from using springs classpath resource to using Freemarkers setClassForTemplateLoading method. I assume this would work: freemarkerConfiguration = new Configuration(); freemarkerConfiguration.setClassForTemplateLoading(this.getClass(), ""); Template freemarkerTemplate = freemarkerConfiguration.getTemplate("/email/vendor.tpl"); yet, I always get a FileNotFoundException. Can someone explain the best way to obtain a template from the classpath? Thanks.

  • Need help understanding Generics, How To Abstract Types Question.

    - by kmacmahon
    I could use some really good links that explain Generics and how to use them. But I also have a very specific question, relater to working on a current project. Given this class constructor: public class SecuredDomainViewModel<TDomainContext, TEntity> : DomainViewModel<TDomainContext, TEntity> where TDomainContext : DomainContext, new() where TEntity : Entity, new() And its creation this way: DomainViewModel d; d = new SecuredDomainViewModel<MyContext, MyEntityType>(this.context, selectedProtectedItem); Assuming I have 20 EntityTypes within MyContext, is there any easier way to call the constructor without a large switch statement? Also, since d is DomainViewModel and I want to access methods for SecuredDomainViewModel, it seems I need to do this: if (((SecuredDomainViewModel<MyContext, MyEntityType>)d).IsBusy) But again "MyEntityType" could actually be one of 20 types. Is there anyway to write these types of statements where MyEntityType is returned from some sort of Reflection?

  • Why is XHTML1.1 dated *before* XHTML1.0 ? What is the preferred XHTML today?

    - by Cheeso
    I'm not clear on the status of XHTML - v1.0 and v1.1. Can someone explain which is preferred at this point, and why? The specs from w3c say that XHTML 1.1 predates* XHTML 1.0, which is exactly counter-intuitive, to me. http://www.w3.org/TR/xhtml11/ - W3C Recommendation 31 May 2001 http://www.w3.org/TR/xhtml1/ - W3C Recommentation, updated 1 August 2002 Also, I noted earlier today that the latest version of htmltidy emits XHTML 1.0, when I request xhtml. Hmmm....Even though the XHTML 1.1 spec is 9 years old, it's still not supported by mainstream tools. That suggests that XHTML 1.1 is either completely unnecessary or spurious. Which one should I use if I am authoring pages today? What if I am building tools - should I bother to support both? Or do I need only one? Thanks.

  • Big 0 theta notation

    - by niggersak
    Can some pls help with the solution Use big-O notation to classify the traditional grade school algorithms for addition and multiplication. That is, if asked to add two numbers each having N digits, how many individual additions must be performed? If asked to multiply two N-digit numbers, how many individual multiplications are required? Suppose f is a function that returns the result of reversing the string of symbols given as its input, and g is a function that returns the concatenation of the two strings given as its input. If x is the string hrwa, what is returned by g(f(x),x)? Explain your answer - don't just provide the result!
