• Processor, OS : 32bit, 64 bit

  - by Sandbox

  I am new to programming and come from a non-CS background (no formal degree). I mostly program winforms using C#. I am confused about 32 bit and 64 bit.... I mean, have heard about 32 bit OS, 32 bit processor and based on which a program can have maximum memory. How it affects the speed of a program. There are lot more questions which keep coming to mind. I tried to go through some Computer Organization and Architecture books. But, either I am too dumb to understand what is written in there or the writers assume that the reader has some CS background. Can someone explain me these things in a plain simple English or point me to something which does that. EDIT: I have read things like In 32-bit mode, they can access up to 4GB memory; in 64-bit mode, they can access much much more....I want to know WHY to all such things. BOUNTY: Answers below are really good....esp one by Martin. But, I am looking at a thorough explanation, but in plain simple English.

• Which of the following Java coding fragments is better?

  - by Simon

  This isn't meant to be subjective, I am looking for reasons based on resource utilisation, compiler performance, GC performance etc. rather than elegance. Oh, and the position of brackets doesn't count, so no stylistic comments please. Take the following loop; Integer total = new Integer(0); Integer i; for (String str : string_list) { i = Integer.parse(str); total += i; } versus... Integer total = 0; for (String str : string_list) { Integer i = Integer.parse(str); total += i; } In the first one i is function scoped whereas in the second it is scoped in the loop. I have always thought (believed) that the first one would be more efficient because it just references an existing variable already allocated on the stack, whereas the second one would be pushing and popping i each iteration of the loop. There are quite a lot of other cases where I tend to scope variables more broadly than perhaps necessary so I thought I would ask here to clear up a gap in my knowledge. Also notice that assignment of the variable on initialisation either involving the new operator or not. Do any of these sorts of semi-stylistic semi-optimisations make any difference at all?

• Should I be worried if I don't get any internships by 3rd year's end?

  - by karamba

  I am in some mediocre college in some corner of India. Am about to complete 3rd year C.S. in a month and a half. I have no idea how to go about "finding an internship" as everyone seems to put it. Looking at online advice, I find that a primary way is to "use your contacts". I am sad to say that I don't have many friends(those I have, I am trying to get help from them for all it's worth), and my family can't help me as they have no idea about the software industry. My college has no official facility for aiding students in this, and the few faculty members who had contacts in "whatever" part of the industry have favoured some students that they have personally come to know. (Though I hear that the "internships" they got involve them stocking equipment in some small companies.... still it's something?) I'm getting nervous. I am considering just spending the coming summer refining my skills in C++ and begin learning MySQL and C#, both of which I have zero experience in. Maybe work on my own project... like a library management system. Relative to those in my college, I think I am among the best programmers there, but that isn't saying much as a lot of students can barely write basic code. I have experience in teaching myself C++, and DirectX9 having created a Tetris clone, some basic 3D apps (bouncing balls), and a basic console-based, text-file-database-using library management system (which I plan to improve this summer). Is it alright if I spend my summer so? Will I be able to get a job later on? I know I have to improve my social skills to get anywhere in life, and I will try, but say I am stuck like this till 4th year's end... will such self studying, online learning help me in landing a decent job? Perhaps after I have learned a bit more, joining some open source project?

• [MVC] logic before dispatcher + controller?

  - by Spoonface

  I believe for a typical MVC web application the router / dispatcher routine is used to decide which controller is loaded based primarily on the area requested in the url by the user. However, in addition to checking the url query string, I also like to use the dispatcher to check whether the user is currently logged in or not to decide which controller is loaded. For example if they are logged in and request the login page, the dispatcher would load their account instead. But is this a fairly non-standard design? Would it violate MVC in any way? I only ask as the examples I've read through this weekend have had no major calculations performed before the dispatcher routine, and commonly check whether the user is logged in or not per controller, and then redirect where necessary. But to me it seems odd to redirect a logged in user from the login area to account area if you could just load the account controller in the first place? I hope I've explained my consternation well enough, but could anyone offer some details on how they handle logged in users, and similar session data?

• HTML5 Drag and Drop styles not displaying on Windows Server 2003

  - by NoR

  I'm working on a file upload utility based on Valum's Ajax-Uploader. The idea is similar to the Gmail attachment process. The user should be able to drag a file from the desktop into the browser window and onto the file upload area to get it to upload. This works fine in the browsers that support this functionality (Firefox 3.6+, Chrome 7+). The problem I'm running into are the styles that should be re-drawn when the user: Drags the file anywhere in the browser Drags the file into the upload area I have tested in the exact same browser versions on WinXP, Vista, and Win7. The appropriate styles are redrawn. However, in Windows Server 2003, they do not. In Win2003, when I inspect the div that should be redrawn via Firebug, the "drop-area" and "drop-area-active" classes are applied correctly. Firebug even shows the correct style declarations, but the changes are never visible. The only difference between FF and Chrome that I'm able to spot is that in Chrome, the "drop-area-active" style is displayed for a split second when the user drops the file. I'm not positive that it is a Windows2003 issue, but that's the only OS in which I'm able to recreate the bug.

• Creating a assertClass() method in JUnit

  - by Mike

  Hi, I'm creating a test platform for a protocol project based on Apache MINA. In MINA when you receive packets the messageReceived() method gets an Object. Ideally I'd like to use a JUnit method assertClass(), however it doesn't exist. I'm playing around trying to work out what is the closest I can get. I'm trying to find something similar to instanceof. Currently I have: public void assertClass(String msg, Class expected, Object given) { if(!expected.isInstance(given)) Assert.fail(msg); } To call this: assertClass("Packet type is correct", SomePacket.class, receivedPacket); This works without issue, however in experimenting and playing with this my interest was peaked by the instanceof operator. if (receivedPacket instanceof SomePacket) { .. } How is instanceof able to use SomePacket to reference the object at hand? It's not an instance of an object, its not a class, what is it?! Once establishing what type SomePacket is at that point is it possible to extend my assertClass() to not have to include the SomePacket.class argument, instead favouring SomePacket?

• MYSQL variables - SET @var

  - by Lizard

  I am attempting to create a mysql snippet that will analyse a table and remove duplicate entries (duplicates are based on two fields not entire record) I have the following code that works when I hard code the variables in the queries, but when I take them out and put them as variables I get mysql errors, below is the script SET @tblname = 'mytable'; SET @fieldname = 'myfield'; SET @concat1 = 'checkfield1'; SET @concat2 = 'checkfield2'; ALTER TABLE @tblname ADD `tmpcheck` VARCHAR( 255 ) NOT NULL; UPDATE @tblname SET `tmpcheck` = CONCAT(@concat1,'-',@concat2); CREATE TEMPORARY TABLE `tmp_table` ( `tmpfield` VARCHAR( 100 ) NOT NULL ) ENGINE = MYISAM ; INSERT INTO `tmp_table` (`tmpfield`) SELECT @fieldname FROM @tblname GROUP BY `tmpcheck` HAVING ( COUNT(`tmpcheck`) > 1 ); DELETE FROM @tblname WHERE @fieldname IN (SELECT `tmpfield` FROM `tmp_table`); ALTER TABLE @tblname DROP `tmpcheck`; I am getting the following error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '@tblname ADD `tmpcheck` VARCHAR( 255 ) NOT NULL' at line 1 Is this because I can't use a variable for a table name? What else could be wrong or how wopuld I get around this issue. Thanks in adavnce

• Defining implicit and explicit casts for C# interfaces

  - by ehdv

  Is there a way to write interface-based code (i.e. using interfaces rather than classes as the types accepted and passed around) in C# without giving up the use of things like implicit casts? Here's some sample code - there's been a lot removed, but these are the relevant portions. public class Game { public class VariantInfo { public string Language { get; set; } public string Variant { get; set; } } } And in ScrDictionary.cs, we have... public class ScrDictionary: IScrDictionary { public string Language { get; set; } public string Variant { get; set; } public static implicit operator Game.VariantInfo(ScrDictionary s) { return new Game.VariantInfo{Language=sd.Language, Variant=sd.Variant}; } } And the interface... public interface IScrDictionary { string Language { get; set; } string Variant { get; set; } } I want to be able to use IScrDictionary instead of ScrDictionary, but still be able to implicitly convert a ScrDictionary to a Game.VariantInfo. Also, while there may be an easy way to make this work by giving IScrDictionary a property of type Game.VariantInfo my question is more generally: Is there a way to define casts or operator overloading on interfaces? (If not, what is the proper C# way to maintain this functionality without giving up interface-oriented design?)

• Right Language for the Job

  - by Manoj

  Using the right language for the job is the key - this is the comment I read in SO and I also belive thats the right thing to do. Because of this we ended up using different languages for different parts of the project - like perl, VBA(Excel Macros), C# etc. We have three to four languages currently in use inside the project. Using the right language for the job has made it immensly more easy to do automate a job, but of late people are complaining that any new person who has to take over the project will have to learn so many different languages to get started. Also it is difficult to find such kind of person. Please note that this is a one to two person working on the project maximum at a given point of time. I would like to know if the method we are following is right or should we converge to single language and try to use it across all the job even though another language might be better suited for it. Your experenece related to this would also help. Languages used and their purpose: Perl - Processing large text file(log files) C# with Silverlight for web based reporting. LabVIEW for automation Excel macros for processing data in excel sheets, generating graphs and exporting to powerpoint.

• Prototype or jQuery for DOM manipulation (client-side dynamic content)

  - by luiggitama

  I need to know which of these two JavaScript frameworks is better for client-side dynamic content modification for known DOM elements (by id), in terms of performance, memory usage, etc.: Prototype's $('id').update(content) jQuery's jQuery('#id').html(content) BTW, both libraries coexist with no conflict in my app, because I'm using RichFaces for JSF development, that's why I can use "jQuery" instead of "$". I have at least 20 updatable areas in my page, and for each one I prepare content (tables, option lists, etc.), based on some user-defined client-side criteria filtering or some AJAX event, etc., like this: var html = []; int idx = 0; ... html[idx++] = '<tr><td class="cell"><span class="link" title="View" onclick="myFunction('; html[idx++] = param; html[idx++] = ')"></span>'; html[idx++] = someText; html[idx++] = '</td></tr>'; ... So here comes the question, which is better to use: // Prototype's $('myId').update(html.join('')); // or jQuery's jQuery('#myId').html(html.join('')); Other needed functions are hide() and show(), which are present in both frameworks. Which is better? Also I'm needing to enable/disable form controls, and to read/set their values. Note that I know my updatable area's id (I don't need CSS selectors at this point). And I must tell that I'm saving these queried objects in some data structure for later use, so they are requested just once when the page is rendered, like this: MyData = {div1:jQuery('#id1'), div2:$('id2'), ...}; ... div1.update('content 1'); div2.html('content 2'); So, which is the best practice?

• Jquery Mobile 1.2 Multiple Checkbox Selection Issue

  - by user1819957

  I'm coding a Jquery Mobile 1.2, Jquery 1.8.2, css, and HTML 5 based app that I need to allow the user to select multiple images and execute a command. The following works if I do NOT use the jquery.mobile-1.2.0.min.js library: CSS Code: .image-checkbox-container input[type="checkbox"]{ display: none; } .image-checkbox-container img{ border: 0; margin: 4px; } HTML: JQuery: $('.image-checkbox-container img').live('click', function(){ if(!$(this).prev('input[type="checkbox"]').prop("checked")){ $(this).prev('input[type="checkbox"]').prop("checked", true); this.style.border = '4px solid #38A'; this.style.margin = '0px'; }else{ $(this).prev('input[type="checkbox"]').prop("checked", false); this.style.border = '0'; this.style.margin = '4px'; } }); As soon as I add in the jquery.mobile-1.2.0.min.js library to the code it does not function correctly anymore. The unchecking/unselecting of the checkboxes does not work. I attempted to use the checkboxradio("refresh") but did not have any luck. Any suggestions would be much appreciated. Thanks

• How to display controllers with proper aligning in iPhone screen ?

  - by chatcja

  I have a issue of displaying information in iPhone screen. Case is as follows. I crated a view-based application in Xcode name as myView. Then open myViewViewController.xib interface builder, change back groung color and added label at top-let (0, 0) of the view. Then I add new file named as myView2ViewController, which is subclass of UIViewController and corresponding XIB also generated. Open myView2ViewController in IB and added a label at top-left as previous. Also changed the background color. In the "applicationDidFinishLaunching" of AppDeligate do following myView2ViewController *mView = [[myView2ViewController alloc] initWithNibName:@"myView2ViewController" bundle:nil]; [window addSubview:mView.view]; When I run the application, it is shown as upper part of the Label is sheared. It seems as whole UI has been moved 20 px upper (Because, there is a horizontal space in the bottom). I guess this is due to some positioning. But still I could not found any way to fix it. Hope somebody will help me to identify this issue !!

• Social Networking & Network Affiliations

  - by Code Sherpa

  Hi. I am in the process of planning a database for a social networking project and stumbled upon this url which is a (crude) reverse engineered guess at facebook's schema: http://www.flickr.com/photos/ikhnaton2/533233247/ What is of interest to me is the notion of "Affiliations" and I am trying to fully understand how they work, technically speaking. Where I am somewhat confused is the NetworkID column in the FacebookGroups", "FacebookEvent", and "Affiliations" tables (NID in Affiliations). How are these network affiliations interconnected? In my own project, I have a simple profile table: CREATE TABLE [dbo].[Profiles]( [profileid] [int] IDENTITY(1,1) NOT NULL, [userid] [uniqueidentifier] NOT NULL, [username] [varchar](255) COLLATE Latin1_General_CI_AI NOT NULL, [applicationname] [varchar](255) COLLATE Latin1_General_CI_AI NOT NULL, [isanonymous] [bit] NULL, [lastactivity] [datetime] NULL, [lastupdated] [datetime] NULL, CONSTRAINT [PK__Profiles__1DB06A4F] PRIMARY KEY CLUSTERED ( [profileid] ASC )WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY], CONSTRAINT [PKProfiles] UNIQUE NONCLUSTERED ( [username] ASC, [applicationname] ASC )WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY] ) ON [PRIMARY] One profile can have many affiliations. And one affiliation can have many profiles. And I would like to design it in such a way that relationships between affiliations tells me something about the associated profiles. In fact, based on the affiliations that users select, I would like to know how to infer as many things as possible about that person. My question is, how should I be designing my network affiliation tables and how do they operate per my above requirements? A rough SQL schema would be appreciated in your response. Thanks in advance...

• Access to and availability of private member functions in C++

  - by David

  I am wandering the desert of my brain. I'm trying to write something like the following: class MyClass { // Peripherally Related Stuff public: void TakeAnAction(int oneThing, int anotherThing) { switch(oneThing){ case THING_A: TakeThisActionWith(anotherThing); break; //cases THINGS_NOT_A: }; }; private: void TakeThisActionWith(int thing) { string outcome = new string; outcome = LookUpOutcome(thing); // Do some stuff based on outcome return; } string LookUpOutcome(int key) { string oc = new string; oc = MyPrivateMap[key]; return oc; } map<int, string> MyPrivateMap; Then in the .cc file where I am actually using these things, while compiling the TakeAnAction section, it [CC, the solaris compiler] throws an an error: 'The function LookUpOutcome must have a prototype' and bombs out. In my header file, I have declared 'string LookUpOutcome(int key);' in the private section of the class. I have tried all sorts of variations. I tried to use 'this' for a little while, and it gave me 'Can only use this in non-static member function.' Sadly, I haven't declared anything static and these are all, putatively, member functions. I tried it [on TakeAnAction and LookUp] when I got the error, but I got something like, 'Can't access MyPrivateMap from LookUp'. MyPrivateMap could be made public and I could refer to it directly, I guess, but my sensibility says that is not the right way to go about this [that means that namespace scoped helper functions are out, I think]. I also guess I could just inline the lookup and subsequent other stuff, but my line-o-meter goes on tilt. I'm trying desperately not to kludge it.

• Alternative to Altova's MissionKit

  - by nomad311

  Anyone know of any good alternatives (other than those listed below which really are only good at specific XML development tasks)? The Why (if you're interested): I've been doing XML development on and off for years now, but someone brought XMLSpy to my attention recently, and it is awesome - the price isn't. Lately I've been using a combination of: Notepad++ (modifying XML) EditX (validating/debugging XML) Eclipse (designing schemas) and MS Visual Studio (validating schemas) ...based on which makes the task(s) easiest. But, I've just found out that we will be using XSL transformations to generate XML in the future. I've never used mission kit before, but I'm just short of positive XMLSpy replaces all the above mentioned tool for XML development. And if their XSL tools are anywhere near the caliber of XMLSpy ...simply put I need it. I don't believe that I can convince the budgeting types to buy licenses for MissionKit at $1000 each (won't stop me from trying). In the mean while some research on alternatives won't hurt, but a few Google queries has only revealed that not many people pay for Altova's (overpriced?) software as there are mostly links to P2P sites for downloading a more free-like version of MissionKit.

• Switching application-wide theme programmatically?

  - by Cheezmeister

  EDIT: Related question here: Multi theme support in android app I'm attempting to get a user-chosen theme and feel like I'm frustratingly close. Defining the theme in AndroidManifest.xml works as it should, but (as best I can tell) can't change based on app preferences: <application android:theme="@style/theme_sunshine" android:icon="@drawable/icon" android:label="@string/app_name"> Alternatively, setting it dynamically in each activity also works: someChosenTheme = PreferenceManager.getDefaultSharedPreferences(this).getString("themePreference", "theme_twilight"); setTheme(someOtherChosenTheme); But that seems messy, and I'd rather set the theme for the entire app in one place. My first thought was to grab the application context as soon as my main activity launches and do it there: getApplicationContext().setTheme(R.style.theme_dummy); As best I can tell[0], this ought to do the trick, but in fact it's not doing anything--the entire app has the default Android style. Is the above valid, and if so, might I be doing something else dumb? I'm working in API level 3 if that matters. Prods in the right direction greatly appreciated!

• Can I use a UINavigationController as the detail view of a UISplitViewController?

  - by B Sweigard

  I'm running into a problem with an iPad app where I would like to have UINavigationControllers in both of the views within a UISplitView. I've looked through other similar questions here, but most link to a tutorial online that doesn't completely solve the problem. Here's a 2-minute walkthrough to re-create the problem I'm having: Create a New Project in XCode, starting from the Split View-based Application template. Add the following NSLog statement as the first line within the DetailViewController's willHideViewController method: NSLog(@"toolbar: %@", toolbar); If you run the application now, the log will show that the DetailViewController's toolbar is alive and well. Now... Open MainWindow.xib and expand the SplitViewController. Drag a Navigation Controller from the library on top of the DetailViewController. Expand the new Navigation Controller and change the class of the UIViewController within to a DetailViewController. Ctrl-drag from the SplitViewController to the DetailViewController and assign it as the delegate. Save MainWindow.xib and run the app again. At this point, the detail view has a navigation bar and an empty toolbar. If you view the logs, you should find that the toolbar is null. Why is this? Am I missing some sort of connection in Interface Builder? Is the navigation bar the problem for some reason? Unlike the tutorial at http://www.cimgf.com/2010/05/24/fixing-the-uisplitviewcontroller-template/, I would like to keep both the navigation bar and the toolbar (preferably with the toolbar at the top when in portrait and not visible when in landscape), so that I still have a functional "Back" button when the iPad is in portrait orientation. Does anyone have any suggestions for fixing this problem? An example project with this sort of set-up would be ideal.

• Migrate from Oracle to MySQL

  - by Cassy

  Hi together. We ran into serious performance problems with our Oracle database and we would like to try to migrate to a MySQL-based database (either MySQL directly or, more preferrable, Infobright). The thing is, we need to let the old and the new system overlap for at least some weeks if not months, before we actually know, if all features of the new database match our needs. So, here is our situation: The Oracle database consists of multiple tables with each millions of rows. During the day, there are literally thousands of statements, which we cannot stop for migration. Every morning, new data is imported into the Oracle database, replacing some thousands of rows. Copying this process is not a problem, so we could, in theory, import in both databases in parallel. But, and here lies the challenge, for this to work, we need to have an export from the Oracle database with a consistent state from one day. (We cannot export some tables on Monday and some others on Tuesday, etc.) This means, that at least the export should be finished in less than one day. Our first thought was to dump the schema, but I wasn't able to find a tool to import an Oracle dump file into mysql. Exporting tables in CSV files might work, but I'm afraid it could take too long. So my question now is: What should I do? Is there any tool to import Oracle dump files into MySQL? Does anybody have any experience with such a large-scale migration? Thanks in advance, Cassy PS: Please, don't suggest performance optimization techniques for Oracle, we already tried a lot :-)

• Reverse wildcard search in codeigniter

  - by Andy Platt

  I am implementing a snippet-based content management system into my current project. Snippets can be associated with a page either by exact match of the full url falling back to a wildcard match on a partial url or finally a default snippet. To implement this I have a created table of page associations with a wildcard flag, the system first checks the current url against the non-wildcard associations and if it doesn't find a match it checks against the partial url's where the wildcard flag is set. In order to achieve this I am getting all the partial url's from the database and putting them into an array then walking the array to check for a match against the current url: protected function _check_wildcard($url = NULL) { if($url) { $q = $this->db->where('wildcard' ,'Y') ->from('content') ->get(); $wildcards = $q->result_array(); foreach($wildcards AS $wildcard) { if(strpos($url,$wildcard['url']) > 0) { return $wildcard['snipppet_id']; } } } else { return NULL; } } Can anyone suggest a better way to do this - preferably one that doesn't involve having to constantly download the full list of all the wildcards each time I load a page as I am afraid that this will have a negative effect on the scalability of the system down the line?

• Sort MySQL query result by a alphanumeric field

  - by Jason Shultz

  I'm querying a table in a db using php. one of the fields is a column called "rank" and has data like the following: none 1-bronze 2-silver 3-gold ... 10-ambassador 11-president I want to be able to sort the results based on that "rank" column. any results where the field is "none" get excluded, so those don't factor in. As you can already guess, right now the results are coming back like this: 1-bronze 10-ambassador 11-president 2-silver 3-gold Of course, I would like for it to be sorted so it is like the following: 1-bronze 2-silver 3-gold ... 10-ambassador 11-president Right now the query is being returned as an object. I've tried different sort options like natsort, sort, array_multisort but haven't got it to work the way I'm sure it can. I would prefer keeping the results in an object form if possible. I'm passing the data on to a view in the next step. although, it's perfectly acceptable to pass the object to the view and then do the work there. so it's not an issue after all. :) thank you for your help. i'm hoping I'm making sense.

• php array problem ..need expert

  - by user295189

  I have tried this in another post but trying my luck again. My current array that I am making produce a different result than I am wanting. I want to have this kind of out put Row: 0: Column: 1: ID 1 Row: 1: Column: 1: ID 1 Row: 0: Column: 2: ID 2 Row: 1: Column: 2: ID 2 Row: 2: Column: 2: ID 2 Row: 3: Column: 2: ID 2 Row: 0: Column: 3: ID 3 Row: 1: Column: 3: ID 3 As you can see the Rows and columns change based on the ID. So if the ID is same it just go to next row in the same column. However if id is changed it goes to next column and rows start. Currently I my code looks like this for($i=0;$i<count($pv->rawData); $i++) { $relative=0; $relativeTypeID = -1; if ($pv->rawData[$i]->relativeTypeID != $relativeTypeID) { $relativeTypeID = $pv->rawData[$i]->relativeTypeID; $iTypeCount++; } if(!empty($pv->rawData[$i]->description)) { $pv->results[$i][$iTypeCount][0] = $pv->rawData[$i]->description; echo "Row: ".$i.": Column: ".$iTypeCount.": ID".$relativeTypeID." <br>"; } } It gives me the following output Row: 0: Column: 1: ID1 Row: 1: Column: 2: ID1 Row: 2: Column: 3: ID2 Row: 3: Column: 4: ID2 Row: 4: Column: 5: ID2 Row: 5: Column: 6: ID2 Row: 6: Column: 7: ID2 Row: 7: Column: 8: ID2 Row: 8: Column: 9: ID2 Row: 9: Column: 10: ID2 Row: 10: Column: 11: ID2 Row: 11: Column: 12: ID2 Row: 12: Column: 13: ID2 …. …. As you can see the Row and Columns are changing but not with ID number. I appreciate your help Thanks

• My UITextView delegate method doesn't respond

  Hi guys. I would like to start we that i'm not a very good english speaker, so excuse me if something is wrong. So I have this code header file : import @interface macViewController : UIViewController { UINavigationItem *navItem; UITextView *iTextView; } @property (nonatomic, retain) IBOutlet UINavigationItem *navItem; @property (nonatomic, retain) IBOutlet UITextView *iTextView; (IBAction) btnClicked; @end implementation file : import "macViewController.h" @implementation macViewController @synthesize navItem, iTextView; (IBAction) btnClicked { if (self.editing == YES) { self.editing = NO; [iTextView resignFirstResponder]; UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Data Saved" message:@"Your data was saved" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; } else { self.editing = YES; [iTextView becomeFirstResponder]; } NSLog(@"works"); self.navItem.rightBarButtonItem = self.editButtonItem; self.navItem.rightBarButtonItem.action = @selector(btnClicked); } (void) textViewDidChangeUITextView *)textView { NSLog(@"works"); } So like you guess it's a view based app wich when i tap Edit button the keyboard pops-up then i press Done button and keyboard disappear and appear a alert view. SO I WANTED TO MAKE THEN I TOUCH THE TEXTVIEW, EDIT BUTTON TO BECOME DONE BUTTON ... THE PROBLEM IS THAT THE METHOD I DELEGATE TO IT DOESN'T RESPOND ... (USING CONSOLE I SAW THAT NOTHING HAPPENS) ... I TRIED DIFFERENT CODE BUT ALL = 0 ... PLEASE HELP I'M NEW ...

• JSON element detection

  - by user3614570

  I’ve created a string… {"atts": [{"name": "wedw"}, {"type": "---"}]} I pile a bunch of these together in an array based on user input and attach them to another string to complete a JSON object that tests out as valid. So I end up with a global array called fields with a bunch of these little snippets. So how do I change the name "weds" with a new name? I’ve tried... function changefieldname(pos){ var obj = JSON.parse(jsonstring); var oldname = obj.tracelog.fields[pos].atts[0]["name"]; var newname = document.getElementById("newlogfieldname"+pos).value; fields[pos].replace(oldname, newname); //writejson(); } And a bunch of variations. I know everything is checking out correct interms of the variables pos, oldname, and newname. I also know that fields[pos] returns the string in the array I want to correct but it’s not happy. I also tried converting fields[pos] to a string, but the replace function doesn't work on it. I’m sure there is a good reason.

• Regex for ignoring consecutive quotation marks in string

  - by will-hart

  I have built a parser in Sprache and C# for files using a format I don't control. Using it I can correctly convert: a = "my string"; into my string The parser (for the quoted text only) currently looks like this: public static readonly Parser<string> QuotedText = from open in Parse.Char('"').Token() from content in Parse.CharExcept('"').Many().Text().Token() from close in Parse.Char('"').Token() select content; However the format I'm working with escapes quotation marks using "double doubles" quotes, e.g.: a = "a ""string""."; When attempting to parse this nothing is returned. It should return: a ""string"". Additionally a = ""; should be parsed into a string.Empty or similar. I've tried regexes unsuccessfully based on answers like this doing things like "(?:[^;])*", or: public static readonly Parser<string> QuotedText = from content in Parse.Regex("""(?:[^;])*""").Token() This doesn't work (i.e. no matches are returned in the above cases). I think my beginners regex skills are getting in the way. Does anybody have any hints? EDIT: I was testing it here - http://regex101.com/r/eJ9aH1
