• Eclipse Outline View - Visible JavaScript Categories in Eclipse?

  - by leeand00

  I just found an option in the little white down arrow in Eclipse that reads "Visible Categories..." How can I use this? It seems to me that it could be used to only show functions that have an @category in their comments, but I haven't been able to make that work. If it did work it would be incredibly useful for separating out Unit Tests from their common-functions and separating them from the setUp and tearDown methods, so what is it really for? By the way I'm editing a Javascript file in the Eclipse "Javascript Editor", I don't know if that makes any difference or not.

• how u guys learn coding and programming

  - by dramasea

  Hi, I am a newbie on programming and currently still learning. Can you contribute your opinion on how to learn that faster. I learn every single element of the language such as Javascript date object methods and properties: http://www.w3schools.com/jsref/jsref_obj_date.asp but it is pretty much all the same, should i read through it? or i just left it. You know that's very boring with just reading. So, can I ask those professional programmer, do you also read these when you learn programming?

• WCF Proxy generation

  - by dragonfly

  Hi, I'm generating proxy using svcutil tool. My contract methods return objects of particular type. However generated proxy client interface has return value of type object. What is more I get exception with message: System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail] : The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:name. The InnerException message was 'XML 'Element' 'http://tempuri.org/:name' does not contain expected attribute 'http://schemas.microsoft.com/2003/10/Serialization/:Type'. The deserializer has no knowledge of which type to deserialize. Check that the type being serialized has the same contract as the type being deserialized.'. Please see InnerException for more details. Any ideas what's going on?

• RESTful API Documentation

  - by PartlyCloudy

  I'm going to design a RESTful API soon, thus I need to describe it in order to enable other people to start implementing clients using it. I've looked around a bit, but unfortunately, I've not found any standardized form of describing web-based RESTful services. What I'am looking for is something like JavaDoc, although it don't have to be generated out of any sort of code. I'm also not talking about something like WADL, I rather want to have some human-readable documentation I can hand out. Due to the nature of RESTful web-based services, it should be quite easy to standardize a documentation. It should just list available ressources, corresponding URIs, allowed methods, content-types and describe the availabe actions. Do you have any suggestions therefore? Thanks in advance & Greets

• How to determine MS Access field size via OleDb

  - by Andy

  The existing application is in C#. During startup the application calls a virtual method to make changes to the database (for example a new revision may need to calculate a new field or something). An open OleDb connection is passed into the method. I need to change a field width. The ALTER TABLE statement is working fine. But I would like to avoid executing the ALTER TABLE statement if the field is already the appropriate size. Is there a way to determine the size of an MS Access field using the same OleDb connection?

• How to access the Principal from a Java service object without using FlexContext?

  - by Marplesoft

  We're building some Java objects that are exposed via BlazeDS to our flex client application. So basically the BlazeDS messagebroker servlet instantiates and invokes methods on these objects in response to client requests. Works great. We're using app server-based authentication and have set up a security constraint on the <destination> elements in the remoting-config.xml file element to prevent unauthenticated clients from being able to access these remote java objects. Again, works fine. However, there are several places within the implementation of these java objects where we want to get the currently logged on user's username. Right now we are doing this via FlexContext.getUserPrincipal(), which gives access to this but we have a nagging concern that we don't like the idea that the implementation of these objects (the service layer) has a hard dependency on a BlazeDS class. But we're not sure how else to get access to this. The same applies to accessing the ServletContext and such. Any ideas?

• Creating a common selector class with UITableView or UIPicker

  - by trevrosen

  I have several places in my app where I need to select a Foo for further processing from a list of Foo objects. I'd like to do this as a modal view, but neither UIPicker nor UITableView seems to lend itself to the standard approach, since the usual way to do a modal view controller involves setting the parent view controller up as the delegate, and both of those classes need to implement data source protocols, etc. Implementing the data source and selection protocol methods in my parent view controller defeats the purpose of trying to use one common class for implementing this modal selector screen all over my app. Does anyone have any solutions to this problem or am I effectively stuck implementing this selector class over and over again?

• Dealing with the lack of closures in Objective-C

  - by Sean Clark Hess

  Maybe it's just the fact that I've been using http://nodejs.org/ lately, but the lack of closures in Objective-C (iphone) has been really hard to work around. For example, I'm creating service classes. Each service class can have several methods, each of which makes a different URL request. I can use the delegate pattern, but that means that I have to create a new service each time I want to call a method on it (because it has to store the delegate and selector for that request, and new method calls would overwrite them). Even more difficult for me is the fact that I can't easily keep local variables around in the scope for a callback. I have to store anything I want to send back to the delegate on the service class itself, which makes it harder to have more than one method on each class. How do you pros do it? Should I just quit whining and do it another way?

• How to tell a rightCalloutAccessoryView has been touched for MapKit

  - by iamdadude

  I have a MKAnnotationView being allocated with a DetailDisclosure button being displayed on the right side of the annotation. How would I go about knowing when a user clicked on the annotation button? This is what my code looks like right now - UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; pinView.rightCalloutAccessoryView = rightButton; pinView.animatesDrop = YES; Is there a built in method to detect when a accessory view has been touched? I'm guessing it would be like the UITableView methods, but I can't find anything. Thanks for any help.

• Checking existence of file types via extensions bash.

  - by Tommy

  Hi, I need to test if various file types exist in a directory. I've tried $ [ -f *.$fileext] where fileext is the file extension but that does not seem to work. Both of these methods work function checkext() { fileext=$1 ls *.$fileext>/dev/null 2>&1 if [ $? -eq 0 ] then echo "We have $fileext files!" else echo "We don't have any $fileext files!" fi } and function checkext2() { extention=$1 filescheck=(`ls *.$1`) len=${#filescheck[*]} if [ $len -gt 0 ] then echo "We have $extention files!" else if [ $len -eq 0 ] then echo "We don't have any $extention files!" else echo "Error" fi fi } The second method is less tidy as any ls error is shown so I prefer method 1. Could people please suggest any improvements, more elegant solutions e.t.c

• Asp.net override Membership settings at runtime (asp.net mvc)

  - by minal

  I had an application that hooked onto 1 single database. The app now needs to hook into multiple databases. What we want to do is, using the same application/domain/hostname/virtual dir give the user the option on the login screen to select the "App/Database" they want to connect into. Each database has the App tables/data/procs/etc as well as the aspnet membership/roles stuff. When the user enters the username/password and selects (select list) the application, I want to validate the user against the selected applications database. Presently the database connection string for membership services is saved in the web.config. Is there any way I can override this at login time? Also, I need the "remember me" function to work smoothly as well. How does this work when the user comes back to the app in 5 hours... This process should be able to identify the user and application and log in appropriately.

• Creating line graph/chart in vb.net (VS2008)

  - by typoknig

  I am reluctant to ask this question because a lot of similar questions have been asked, but after reading through them I am not getting the info I need. I am trying to follow this tutorial and I think it is going to work ok, but I have a lot of data to put in and the tutorial has the reader create the chart data points manually. I want the data points to be generated from an integer which can change while the program is running (thus the chart size needs to change) and the y coordinate of the data points needs to come from an array. I have attempted to "bind" the data but I am messing it up somehow and I don't even think that is the best way to do what I want. Also, I do not have to use the methods suggested in the tutorial, I am looking for the highest quality most efficient way to generate a line graph in vb.net (VS2008) based on the criteria I previously mentioned.

• Memory leak found with clang but cant release and autorelease crashes

  - by Rudiger

  I have a class that builds a request based on a few passed in variables. The class also has all the delegate methods to receive the data and stores it in a property for the calling class to retrieve. When the class initializes it creates a connection and then returns itself: NSURLConnection *connection; if (self = [super init]) { self.delegate = theDelegate; ...some code here... connection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self startImmediately:YES]; } return self; So I can't release it normally and if I autorelease it crashes. Is it the job of the calling class to release? And if so does just releasing the initilised object also release connection or do you have to release it specifically? If so how would you? Thanks

• Fastest way to call a COM objects method without using a RCW

  - by Nathan W

  I'm trying to find the cleanest and fastest way for calling a COM objects methods. I was using a RCW for the object but every time a new version of the third party COM object comes out its GUID changes which then renders the RCW useless, so I had to change and start using Type mytype = Type.GetTypeFromProgID("MyCOMApp.Application"); so that every time a new version of the COM object comes out I don't have to recomplie and redeploy my app. At the moment I am using refelection like mytype.InvokeMemeber but I feel it is so slow compared to just calling the RCW. How does everyone else tackle the problem of changing 3rd party COM object versions, but still maintaining the speed of a RCW?

• How do I get the SharedPreferences from a PreferenceActivity in Android?

  - by Dave

  Hi, I am using a PreferenceActivity to show some settings for my application. I am inflating the settings via a xml file so that my onCreate (and complete class methods) looks like this: public class FooActivity extends PreferenceActivity { @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); addPreferencesFromResource(R.xml.preference); } } The javadoc of PreferenceActivity states, that These preferences will automatically save to SharedPreferences as the user interacts with them. To retrieve an instance of SharedPreferences that the preference hierarchy in this activity will use, call getDefaultSharedPreferences(android.content.Context) with a context in the same package as this activity. But how I get the name of the SharedPreference in another Activity? I can only call getSharedPreferences(name, mode) in the other activity but I need the name of the SharedPreference which was used by the PreferenceActivity. What is the name or how can i retrieve it?

• Implementation of ECC in Java

  - by Rookie_22

  While trying to encrypt a given input using Elliptic Curve Cryptography in Java I'm using the following algorithms for generating the cipher and the key: KeyPairGenerator g = KeyPairGenerator.getInstance("ECDSA"); Cipher cipher = Cipher.getInstance("ECIES"); Now as expected, the cipher isn't accepting the keys generated by the ECDSA algorithm. I get the error as - must be passed IE key. I searched for the ciphers being supported by these 2 methods here: http://java.sun.com/javase/6/docs/technotes/guides/security/StandardNames.html#Cipher Unfortunately no else algo is supported for ECC. Has anyone used ECC generated keys to encrypt/decrypt an input? Which algo should I use for both so that they don't clash with each other?

• DataContractJsonSerializer produces list of hashes instead of hash

  - by Jacques

  I would expect a Dictionary object of the form: Dictionary<string,string> dict = new Dictionary<string,string>() {["blah", "bob"], ["blahagain", "bob"]}; to serialize into JSON in the form of: { "blah": "bob", "blahagain": "bob" } NOT [ { "key": "blah", "value": "bob" }, { "key": "blahagain", "value": "bob"}] What is the reason for what appears to be a monstrosity of a generic attempt at serializing collections? The DataContractJsonSerializer uses the ISerializable interface to produce this thing. It seems to me as though somebody has taken the XML output from ISerializable and mangled this thing out of it. Is there a way to override the default serialization used by .Net here? Could I just derive from Dictionary and override the Serialization methods? Posting to hear of any caveats or suggestions people might have.

• open webim ( Mibew Messenger ) time out, reconnecting

  - by Senthil Kumar

  hi, i hope you guys know about webim a.k.a mibew messenger. I know only java, jsp and no idea about php except for some basics. Anyways, i ran this app in my apache2.2 local server. Everything works superb! But if i change my db to a virtual machine and give its address in the config.php (previously i had used localhost), in the visitors page, i get timeout, reconnecting. Login has no prob, so my guess is db connection is fine. I even changed the default page refresh time from 2 to 10. Nothing happens. Still same thing. You guys have any idea?

• Python class design - Splitting up big classes into multiple ones to group functionality

  - by Ivo Wetzel

  OK I've got 2 really big classes 1k lines each that I currently have split up into multiple ones. They then get recombined using multiple inheritance. Now I'm wondering, if there is any cleaner/better more pythonic way of doing this. Completely factoring them out would result in endless amounts of self.otherself.do_something calls, which I don't think is the way it should be done. To make things clear here's what it currently looks like: from gui_events import GUIEvents # event handlers from gui_helpers import GUIHelpers # helper methods that don't directly modify the GUI # GUI.py class GUI(gtk.Window, GUIEvents, GUIHelpers): # general stuff here stuff here One problem that is result of this is Pylint complaining giving me trillions of "init not called" / "undefined attribute" / "attribute accessed before definition" warnings.

• moviePlayBackDidFinish: is not called in application.

  - by srikanth rongali

  In my application I have used these notifications when playing a video. But, The problem is the control of the program is not entering in to the first two methods(moviePreLoadDidFinish and moviePlayBackDidFinish). It is entering into last method. So, after the video is played and I pressed Done button in the video, I cannot touch any object in screen. I mean I used play button for video to play in a view. After the video played the play button is deactivated. - (void) moviePreloadDidFinish:(NSNotification*)notification { } // Notification called when the movie finished playing. - (void) moviePlayBackDidFinish:(NSNotification*)notification { } // Notification called when the movie scaling mode has changed. - (void) movieScalingModeDidChange:(NSNotification*)notification { } I could not get where I was wrong ? Thank You.

• FlexUnit nested async tests

  - by sharvey

  I'm trying to test some async functionality in flex 4. My test has two stages : var loader:MySuperLoader = new MySuperLoader() loader.load('foo.swf'); loader.addEventListener(Event.COMPLETE, Async.asyncHandler(this, function(e:Event):void { loader.removeEventListener(Event.COMPLETE, arguments.callee); var foo:* = loader.content; loader.load('bar.swf'); loader.addEventListener(Event.COMPLETE, Async.asyncHandler(this, function(e:Event):void { /* This call to asyncHandler generates the error */ }, 5000)); }, 5000)); The second call to asyncHandler generates an error saying : Error: Cannot add asynchronous functionality to methods defined by Test,Before or After that are not marked async Is there a way to test such funcitonality?

• Response.TransmitFile() with UNC share (ASP.NET)

  - by frankadelic

  In the comments of this page: http://msdn.microsoft.com/en-us/library/12s31dhy.aspx ..it says that TransmitFile() cannot be used with UNC shares. As far as I can tell, this is the case; I get this error in Event Log when I attempt it: TransmitFile failed. File Name: \\myshare1\e$\file.zip, Impersonation Enabled: 0, Token Valid: 1, HRESULT: 0x8007052e The suggested alternative is to use WriteFile(), however, this is problematic because it loads the file into memory. In my application, the files are 200MB, so this is not going to scale. Is there a method in ASP.NET for streaming files to users that's: scalable (doesn't read entire file into RAM or occupy ASP.NET threads) works with UNC shares Mapping a network drive as a virtual directory is not an option for us. I would like to avoid copying the file to the local web server as well. Thanks

• Ninject : ninject.web - How to apply on a regular ASP.Net Web (!MVC)

  - by No Body

  What I am looking is something similar to the below (http://github.com/ninject/ninject.web.mvc): README.markdown This extension allows integration between the Ninject core and ASP.NET MVC projects. To use it, just make your HttpApplication (typically in Global.asax.cs) extend NinjectHttpApplication: public class YourWebApplication : NinjectHttpApplication { public override void OnApplicationStarted() { // This is only needed in MVC1 RegisterAllControllersIn("Some.Assembly.Name"); } public override IKernel CreateKernel() { return new StandardKernel(new SomeModule(), new SomeOtherModule(), ...); // OR, to automatically load modules: var kernel = new StandardKernel(); kernel.AutoLoadModules("~/bin"); return kernel; } } Once you do this, your controllers will be activated via Ninject, meaning you can expose dependencies on their constructors (or properties, or methods) to request injections.

• Objective-C (iPhone) Memory Management

  - by Steven

  I'm sorry to ask such a simple question, but it's a specific question I've not been able to find an answer for. I'm not a native objective-c programmer, so I apologise if I use any C# terms! If I define an object in test.h @interface test : something { NSString *_testString; } Then initialise it in test.m -(id)init { _testString = [[NSString alloc] initWithString:@"hello"]; } Then I understand that I would release it in dealloc, as every init should have a release -(void)dealloc { [_testString release]; } However, what I need clarification on is what happens if in init, I use one of the shortcut methods for object creation, do I still release it in dealloc? Doesn't this break the "one release for one init" rule? e.g. -(id)init { _testString = [NSString stringWithString:@"hello"]; } Thanks for your helps, and if this has been answered somewhere else, I apologise!!

• How can I locate the indexpath of the UITableviewCell a certain button is in when I click that butto

  I've added a button as an accessory view to uitableviewcell, and I when I press it, I'd like to be able to access the index path of the table view cell it's currently inside of so I can delete/modify the contents of that cell. Should I subclass UIbutton and add make it have it's own index path property? If so, do I need to implement any specific button methods in that subclass of will they automatically be loaded? Any help would be greatly appreciated. Sorry if this is a noobie question.
