• Search for all instances of certain annotation type

  - by user1064918

  Suppose I have this annotation @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.FIELD) public @interface Name { String value(); } This is going to be used as follows @Name("name1") public static Foo foo = new Foo(); I have multiples of these across my project source files. Is there an fairly simple way to search and collect all those "foo"s that're preceded by @Name? In other words, I'd like to write a method that would return a Set<Foo> containing these. Thanks!!!

• How do i make a UILabel act as a link?

  - by user2918086

  I have built a "teacher directory" of sorts, i have the data fill into 3 fields, name, position, and email. All of the fields are UILabels. How do i make it so that you can click on the email and it opens a blank email? @interface PersonDetailTableViewController () @end @implementation PersonDetailTableViewController @synthesize fnameLabel, snameLabel, emailLabel, person; - (void)viewDidLoad { [super viewDidLoad]; [super viewDidLoad]; self.fnameLabel.text = self.person.fname; self.snameLabel.text = self.person.sname; self.emailLabel.text = self.person.email; } (this is the table view controller where the data is being displayed)

• Printing a list using reflection

  - by TFool

  public class Service{ String serviceName; //setter and getter } public class Version{ String VersionID; //setter and getter } public void test(Object list){ //it shd print the obtained list } List< Service list1; //Service is a Bean List< Version list2; //Version is a Bean test(list1); test(list2); Now the test method shd print the obtained list - (i.e) If the list is of type Service ,then serviceName should be printed using its getter. If the list type is Version versionID should be printed. Is it possible to achieve this without using Interface or abstract class?

• How to use multiple restrictions in C# Generics properly?

  - by plouh

  I am attempting to bind c# generics to a class and an interface like this: public class WizardPage<T> where T : UserControl, IWizardControl { private T page; public WizardPage( T page ) { this.page = page; } } And use it with this: public MyControl : UserControl, IWizardControl { //... } Somehow C# doesn't seem to be able to decide that MyControl is a proper instance of T as public class Wizard<T> where T : UserControl, IWizardControl { private WizardPage<T> Page1; public Wizard( MyControl control ) { this.Page1 = new WizardPage(control); } } fails with error The best overloaded method match for 'Controls.WizardPage.WizardPage(T)' has some invalid arguments Am I doing something wrong or is this just not going to work?

• RESTful web service, PUTting an unnamed resource?

  - by James L

  I have a back-end service that creates unique identifiers for resources. The general idea is that resources are saved and versioned, so you can perform: GET http://service/sales/targets/7818181919/latest or GET http://service/sales/targets/7818181919/4 for version 4, and so on. My question is about the most correct way to upload these resources in the first place. How about: PUT http://service/sales/targets/ returning 303 See other /service/sales/targets/ It seems a little wrong as you should PUT and GET from exactly the same place using a resource-oriented interface, but I can't think of a better option. Any ideas?

• How to use .DefaultListCellRenderer

  First, i'm new at Java-programming and my native lang is not english, but still i hope to get some help from you all. What I try to do is a simple java-interface with a jComboBox and a jList.

• Inter-project dependencies

  - by Mike Hordecki

  Hello! I'm doing some Delphi (2010) work this summer, and I've stumbled upon this problem: My project consists of reusable backend library and a bunch of GUIs that tap into its interface. In this circumstances I've decided to make the backend and GUIs separate projects within single project group (I hope my train of thought is correct). The problem is, how can I include units from the backend in a GUI project? I've tried to modify Project Options > Directories and Conditionals but compiler still complains about being unable to find proper .dcu's. Any ideas? Your help will be appreciated.

• how to load local html file into uiwebview iphone

  - by madcoderz

  I'm trying to load a html file into my UIWebView but it won't work. Here's the stage: I have a folder called html_files in my project. Then I created a webView in interface builder and assigned an outlet to it in the viewController. This is the code I'm using to append the html file: -(void)viewDidLoad { NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"html" inDirectory:@"html_files"]; NSData *htmlData = [NSData dataWithContentsOfFile:htmlFile]; [webView loadData:htmlData MIMEType:@"text/html" textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:@""]]; [super viewDidLoad]; } That won't work and the UIWebView is blank. I'd appreciate some help.

• Can a method return an NSRange?

  - by Dan Donaldson

  I have a method that returns an NSRange. When I call this method from outside the class I get a compile error. NSRange tmpRange; tmpRange = [phrase rangeInString:searchString forString:theLetter goingForward:YES]; return tmpRange.location == -1; in the .h file: #import <Foundation/Foundation.h> @interface Phrase : NSObject { } - (NSRange) rangeInString:(NSString *) tgt forString:(NSString *) find goingForward:(BOOL) fwd; @end This method is called within the Phrase object by other methods without problems. The compiler says 'incompatible types in assignment'. Can anyone explain this to me? I assume it has to do with returning an NSRange/struct type value generated outside the object, but I don't know why it works in one place and not the other.

• Xcode method navigation

  - by Bill

  In Xcode 4, I can press Ctrl-6 to get a list of all the methods in the current file. The problem is, if I have private methods declared at the top of my implementation file, say: @interface Foo () -(void)tap:(id)sender; @end @implementation Foo ... -(void)tap:(id)sender { ... } then starting to type "tap" while the method list is visible will just take me to the declaration, since it comes first in the file, when what I really want is the implementation. Is there any way to exclude these declarations from the method list or do I need to resort to separate Foo.h and Foo+Private.h headers? Thanks!

• C++ Boost bind value type {solved}

  - by aaa

  hello. I look in documentation and source code but cannot figure out how to get return value type of boost bind functor. I am trying to accomplish following: 35 template<typename T,size_t N, class F> 36 boost::array<typename F::value_type, N> make_array(T (&input)[N], F unary) { 37 boost::array<typename F::value_type, N> array; 38 std::transform(input, input + N, array.begin(), unary); 39 return array; 40 } where F can be bind functor. the above does not work because functor does not have value_type. for that matter, is there standard interface for unary/binary functor as far as return value. solution: it should be result_type. also equivalent defined are argument_type and first/second_argument_type for binary functions Thanks

• How to arrange labels in a flowlayout manner?

  - by Tim Büthe

  How do I arrange some UILabels and/or UIButtons of a variable length? I just want to add them to a UITableViewCell and they should arrange in a left-to-right flow, much like lines of text in a paragraph. I only found possibilities to create lables with a fixed size and position using "initWithFrame:...". Same seems to be true for Interface Builder, as far as I can tell. Any solution is appreciated no matter if it's done in code or using a custom cell XIB-file.

• javascript call url from different domain

  - by user246114

  Hi, I want to post some data via javascript to another domain. Something like: http://www.othersite.com/submitfunnyname?name=blah The other site (othersite.com) has a REST interface that you can call (well actually this is a get example) to submit a funny name to them. Can I do this already with javascript? I'm a little confused on this - I know if that service wants to return some data, I'd need to use something like JSON-P - even though here I'm submitting some data, I guess the service will return some message structure letting me know the result, so it would have to be JSON-P, right? Thanks

• [iphone] use NSString in other method?!

  - by user134282

  It's really embarrassing but i stuck on it for two hours of trial and error. I declared an NSString in the interface as: NSString *testString; Then i made a property and synthesized it. I allocate it in viewDidLoad with: testString = [[NSString alloc] initWithFormat:@"thats my value: %i", row]; If i want to get the value of the string in another method it always return (null). So the string is empty, but why? how do i make it accessible for every function inside of one class? So i don't want to make a global var just a "global variable inside the class" It's really confusing because as long as i code i never ran into this problem :( thanks a lot for helping me!

• How can i access my custom webpart in sharepoint foundation 2010?

  - by oklahoma_overlord

  Hi, So i just started trying to develop a simple webpart today for a sharepoint foundation i put on a virtual machine. I have no previous experience with sharepoint whatsoever. As i cant run a sharepoint 2010 on my local machine for dev purposes i followed advices in this thread http://social.technet.microsoft.com/Forums/en/sharepoint2010programming/thread/cda807f6-4edf-4efc-8e9b-4d446356c8ae to able to actually develop something (just the registry bit). I created the simple test web part (writes out "hi"), uploaded it to virtual machine, added it with add-spsolution and install-spsolution in powershell with success. When i do get-solution through powershell on my webpart it says deployed = true. What am i missing from here to get it to actually show up somewhere in the web interface so i can add it to a page? Cheers

• C# determining generic type

  - by Chris Klepeis

  I have several templated objects that all implement the same interface: I.E. MyObject<datatype1> obj1; MyObject<datatype2> obj2; MyObject<datatype3> obj3; I want to store these objects in a List... I think I would do that like this: private List<MyObject<object>> _myList; I then want to create a function that takes 1 parameter, being a datatype, to see if an object using that datatype exists in my list.... sorta clueless how to go about this. In Pseudo code it would be: public bool Exist(DataType T) { return (does _myList contain a MyObject<T>?); }

• How to cast/convert form Object in an byte[] array

  - by maddash

  I've got a maybe simple problem, but at the moment I am not able to solve it. I have an Object and I need to convert it into a byte[]. public byte[] GetMapiPropertyBytes(string propIdentifier) { return (byte[])this.GetMapiProperty(propIdentifier); //InvalidCastException } Exception: Unable to cast COM object of type 'System.__ComObject' to class type 'System.Byte[]'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface. So far so good - I've tried to serialize it, but I got another exception - NOT serializable Could someone help me? I need a method to convert it...

• Passing data from one viewcontroller to another

  - by user1392515

  I subclassed two view controllers. The first one is supposed to pass data, a NSUrl object to the second one. .m of the first one: NSURL *temp = [NSURL URLWithString:@"http://example.com"]; UIViewController *presentationsFullScreen_ViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PresentationsFullScreen_ViewController"]; presentationsFullScreen_ViewController.urlToUse = temp; .h of the second one: #import <UIKit/UIKit.h> @interface PresentationsFullScreen_ViewController : UIViewController { NSURL *urlToUse; } @property (nonatomic,retain) NSURL *urlToUse; It is obviously not working and not compiling,telling me essentially that I didn't subclass it and that the property urlToUse is not found on UIViewController. How do I subclass correctly? Thanks!

• How to get all possible generic type in StructureMap?

  - by Soul_Master

  I just used StructureMap few days ago. I use StructureMap for collecting all validator class like the following code. public class BaseClassA {} public class ClassB : BaseClassA {} public class ClassC : BaseClassB {} public BaseClassAValidator : IValidator<BaseClassA>() {} In StructureMap, I only register IValidator interface for BaseClassAValidator class. But I want to get the same result when I call IValidator or IValidator that mean StructureMap should return IValidator where T is requested class or parent class of requested class. Is it possible? Or I need to manually call it.

• Generic collection class?

  - by Mark

  Is there anyway I can do this? class TSOC<TCollection, TValue> : ICollection<TValue>, INotifyCollectionChanged where TCollection : ICollection { private TCollection<TValue> collection; } It doesn't like my definition of collection. I'd prefer the definition to look like TSOC<TCollection> where the user can pass in List<int> or something, but then I need to pull out the "int" to know what interface to implement.

• How do I return an object that is able to execute on the server?

  - by mafutrct

  Coming from a Java background, this is the way I'm thinking: The server provides an object to the client. This object should be able to execute on the server. Server: private string _S = "A"; public interface IFoo { void Bar(); } private class Foo : IFoo { void Bar() { _S = "B";} } public IFoo GetFoo() { return new Foo(); } Client: IFoo foo = serverChannel.GetFoo(); foo.Bar(); Remoting is legacy (everyone keeps pointing to WCF instead) and WCF does not support this at all basically ( http://stackoverflow.com/questions/2431510 ), so how should I implement this kind of behavior? Using 3rd party components is possible iff required. I searched on SO but found no similar question. If this has indeed been answered before, just let me know and I'll delete.

• Can I just release the top object (iPhone)?

  - by yar

  If I release the object that's holding a reference to the variable that I need to release, is that sufficient? Or must I release at every level of the containment hierarchy? I fear that my logic comes from working with a garbage collector for too long. For instance, I assigned to this property of a UIPickerView instance by hand instead of using IB @property(nonatomic, assign) id<UIPickerViewDelegate> delegate Since it's an assign property, I can't just release the reference after I assign it. When I finally release my UIPickerView instance, do I need to do this: [singlePicker.delegate release]; [singlePicker release]; or is the second line sufficient? Also: Are these assign properties the norm, or is that mostly for Interface Builder? I thought that retain properties were the normal thing to expect.

• NSString inheritance

  - by Stef

  Hi, I'm doing an useless thing for my first step in Obj-C @interface String : NSString { int m_isnull; } - (id) init; - (int) isNull; @end @implementation String - (id) init { self = [super init]; m_isnull=1; return self; } - (int) isNull { return m_isnull; } @end test : String *a; a=@"ok"; Works fine, but just 2 little questions 1) When I'm compiling I have this warning warning: incompatible Objective-C types assigning 'struct NSString *', expected 'struct String *' I don't know how to avoid it !? 2) a=@"ok" is a fastest way to initialize a string, but when I'm debugging, I don't stop by at my init constructor why ?
