  • Integrating Google Analytics into GWT application

    - by Domchi
    This should be totally simple but I can't get it working no matter what I try. I'm trying to use Google Analytics with GWT application. From what I understood, there are two way to do it: First is synchronous, by inserting tracking code at the end of <head> section HTML page and then calling this method: public static native void recordAnalyticsHit(String pageName) /*-{ pageTracker._trackPageview(pageName); }-*/; Second is asynchronous, by inserting tracking code just after <body> tag and then calling this method: public static native void recordAnalyticsHit(String pageName) /*-{ _gaq.push(['_trackPageview(' + pageName + ')']); }-*/; When running each of those methods, however, I get this exceptions in hosted mode: [ERROR] [myproject] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (ReferenceError): pageTracker is not defined [ERROR] [myproject] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (ReferenceError): _gaq is not defined When observing site in Firebug, I see that ga.js gets loaded, but that's about it. Did anyone get Analytics working with GWT? Also, does _gaq accept page name as trackPageview parameter, since all the examples I've seen use this call: _gaq.push(['_trackPageview()']); (Of course, that also doesn't work for me.)

  • Ext.data.Store, Javascript Arrays and Ext.grid.ColumnModel

    - by Michael Wales
    I am using Ext.data.Store to call a PHP script which returns a JSON response with some metadata about fields that will be used in a query (unique name, table, field, and user-friendly title). I then loop through each of the Ext.data.Record objects, placing the data I need into an array (this_column), push that array onto the end of another array (columns), and eventually pass this to an Ext.grid.ColumnModel object. The problem I am having is - no matter which query I am testing against (I have a number of them, varying in size and complexity), the columns array always works as expected up to columns[15]. At columns[16], all indexes from that point and previous are filled with the value of columns[15]. This behavior continues until the loop reaches the end of the Ext.data.Store object, when the entire arrays consists of the same value. Here's some code: columns = []; this_column = []; var MetaData = Ext.data.Record.create([ {name: 'id'}, {name: 'table'}, {name: 'field'}, {name: 'title'} ]); // Query the server for metadata for the query we're about to run metaDataStore = new Ext.data.Store({ autoLoad: true, reader: new Ext.data.JsonReader({ totalProperty: 'results', root: 'fields', id: 'id' }, MetaData), proxy: new Ext.data.HttpProxy({ url: 'index.php/' + type + '/' + slug }), listeners: { 'load': function () { metaDataStore.each(function(r) { this_column['id'] = r.data['id']; this_column['header'] = r.data['title']; this_column['sortable'] = true; this_column['dataIndex'] = r.data['table'] + '.' + r.data['field']; // This display valid information, through the entire process console.info(this_column['id'] + ' : ' + this_column['header'] + ' : ' + this_column['sortable'] + ' : ' + this_column['dataIndex']); columns.push(this_column); }); // This goes nuts at columns[15] console.info(columns); gridColModel = new Ext.grid.ColumnModel({ columns: columns });

  • JQuery Validate: only takes the last addMethod?

    - by Neuquino
    Hi, I need to add multiple custom validations to one form. I have 2 definitions of addMethod. But it only takes the last one... here is the code. $(document).ready(function() { $.validator.addMethod("badSelectionB",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_B_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) == -1){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $.validator.addMethod("badSelectionA",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_A_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) == -1){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $("#inscripcionForm").validate( { rules : { nombre : "required", apellido : "required", dni : { required: true, digits: true, }, mail : { required : true, email : true, }, comision_A_6: { badSelectionA:true, }, comision_B_6: { badSelectionB: true, } }, messages : { nombre : "Ingrese su nombre.", apellido : "Ingrese su apellido.", dni : { required: "Ingrese su dni.", digits: "Ingrese solo números.", }, mail : { required : "Ingrese su correo electrónico.", email: "El correo electrónico ingresado no es válido." } }, }); }); Do you have any clue of what is happening?

  • XMPP and Android interaction

    - by Ameya Phadke
    I am currently finding about how to build a XMPP client application on android 2.0.I came across this link which somewhat talks about the same problem.I am a newbie to android dev and thus found the solution given there to be difficult to digest. The system currently has Active MQ as a JMS provider.My job is to fed the messages coming from JMS to the XMPP server and then develope XMPP client on android 2.0 which will listen and show notification to the events pushed by the server. I have following concerns(which might sound foolish) 1.How do I push the events from JMS to the XMPP server which will in turn push them on android? 2.Which XMPP server implementation I should use?I have 3 options * Openfire: Very mature (was a commercial product), but sounds like it's heavyweight, written in Java * Prosody: Lightweight and easy to use, written in Lua. Doesn't have PubSub module yet * Tigase: Also lightweight, written in Java, supports PubSub How do I test and setup these servers.Do I need PubSub funcationality for my app? 3.For XMPP client I came across Smack API given here which is updated like 2 years back.Can anyone please tell me how do I make use of it for Android 2.0.If possible can anyone please mail me latest working Smack jar files. Thanks, Ameya

  • UIView using Quartz rendering engine to display PDF has poor quality compared to original.

    - by Josh Kerr
    I'm using the quartz rendering engine to display a PDF file on the iphone using the 3.0 SDK. The result is a bit blurry compared to a PDF being shown in a UIWebView. How can I improve the quality in the UIView so that I don't need to rewrite my app to use the UIWebView. I'm using pretty much close to the example code that Apple provides. Here is some of my sample code: CGContextRef gc = UIGraphicsGetCurrentContext(); CGContextSaveGState(gc); CGContextTranslateCTM(gc, 0.0, rect.size.height); CGContextScaleCTM(gc, 1.0, -1.0); CGAffineTransform m = CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, rect, 0, false); CGContextConcatCTM(gc, m); CGContextSetGrayFillColor(gc, 1.0, 1.0); CGContextFillRect(gc, rect); CGContextDrawPDFPage(gc, page); CGContextRestoreGState(gc); Apple's tutorial code actually results in a blurry PDF view as well. If you drop the same PDF into a UIWebView you'll see it is actually sharper. Anyone have any ideas? This one issue is holding a two year development project from launching. :(

  • Generate JSON object with transactionReceipt

    - by Carlos
    Hi, I've been the past days trying to test my first in-app purchse iphone application. Unfortunately I can't find the way to talk to iTunes server to verify the transactionReceipt. Because it's my first try with this technology I chose to verify the receipt directly from the iPhone instead using server support. But after trying to send the POST request with a JSON onbject created using the JSON api from google code, itunes always returns a strange response (instead the "status = 0" string I wait for). Here's the code that I use to verify the receipt: - (void)recordTransaction:(SKPaymentTransaction *)transaction { NSString *receiptStr = [[NSString alloc] initWithData:transaction.transactionReceipt encoding:NSUTF8StringEncoding]; NSDictionary *jsonDictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"algo mas",@"receipt-data",nil]; NSString *jsonString = [jsonDictionary JSONRepresentation]; NSLog(@"string to send: %@",jsonString); NSLog(@"JSON Created"); urlData = [[NSMutableData data] retain]; //NSURL *sandboxStoreURL = [[NSURL alloc] initWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"]]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]]; NSLog(@"will create connection"); [[NSURLConnection alloc] initWithRequest:request delegate:self]; } maybe I'm forgetting something in the request's headers but I think that the problem is in the method I use to create the JSON object. HEre's how the JSON object looks like before I add it to the HTTPBody : string to send: {"receipt-data":"{\n\t\"signature\" = \"AUYMbhY ........... D0gIjEuMCI7Cn0=\";\n\t\"pod\" = \"100\";\n\t\"signing-status\" = \"0\";\n}"} The responses I've got: complete response { exception = "java.lang.IllegalArgumentException: Property list parsing failed while attempting to read unquoted string. No allowable characters were found. At line number: 1, column: 0."; status = 21002; } Thanks a lot for your guidance.

  • Version control a content management system?

    - by Mike
    I have the following directory structure in the CMS application we have written: /application /modules /cms /filemanager /block /pages /sitemap /youtube /rss /skin /backend /default /css /js /images /frontend /default /css /js /images Application contains code specific to the current CMS implementation, i.e code for this specific cms. Modules contain reusable portions of code that we share across projects, such as libraries to work with youtube or rss feeds. We include these as git submodules, so that we can update the module in any website and push the changes back across all other projects. It makes it really easy to apply a change to our code and distribute it. We wanted to turn the CMS into a module so we get the same benefit - we can run the entire project under source control, then update the cms as required through a git-submodule. We have run into a problem however: the cms requires javascript/images/css in order for it to work correctly. Things we have thought about: We could create 2 submodules, one for cms-skin and one for cms, but this means you cannot "git pull" one version without having some idea of which versions of skin work with which versions of cms. i.e version 1.2.2 CMS might have issues with 1.0.3 CMS-Skin We could add the skin to the cms module but this has the following problems: Skin should be available on the document root, module code shouldn't be, and if it is it should probably be secured via .htaccess It doesn't seem to make any sense bundling assets with php code We could create a symlink between /skin/backend/ to go to /modules/cms/skin but does this cause any security problems, and do we want to require something like a symlink for the application to work? We could create a hook for git or a shell script that copies files from modules/cms/skin to skin/backend when an update occurs, but this means we lose the ability to edit CMS core files in a project then push them back How is this typically done in large scale cms's? How is it possible to get the source code for a cms under version control, work on the application for a client, then update the sourcecode as releases and given by the vendor? How do applications like Magento or Drupal do this?

  • iPhone Keychain Questions

    - by AO
    Some questions: * Is there some way to view the data present in the iPhone keychain? * The items an application adds, cannot be accessed by any other application, can it? * What is the purpose of the identifier and access group in the initialization? My guess is that the identifier is simply used to find items but I'm a little bit unsure of the access group. If the access group is assigned nil, all applications can access the items? If the access group is assigned X, could the items be accessed by another application with the same string X as access group or what is the purpose of the access group in this case? * Is the data in the keychain removed when the application is removed? If not, how do I achieve that? And finally: I can't get the KeychainItemWrapper (Apple example) to work. I've added the KeychainItemWrapper files to my project and when running it on the phone, an exception is thrown by SecItemAdd, saying that one or more parameters were not valid (result code -50). The code triggering the SecItemAdd follows: KeychainItemWrapper* wrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"something" accessGroup:@"com.company.whatever"]; [wrapper setObject:@"this is my password" forKey:@"password"]; NSLog(@"Password: %@", [wrapper objectForKey:@"password"]); The code can be found at http://developer.apple.com/iphone/library/samplecode/GenericKeychain/index.html

  • Opening a LWJGL window from a SWT app on Mac

    - by TomA
    I have a SWT app that opens a OpenGL window (using the LWJGL library) after a button is pressed. Works fine on Windows. On Mac, I get this error: 2010-03-05 02:28:25.315 java[1315:a07] [Java CocoaComponent compatibility mode]: Enabled 2010-03-05 02:28:25.316 java[1315:a07] [Java CocoaComponent compatibility mode]: Setting timeout for SWT to 0.100000 2010-03-05 02:28:25.317 java[1315:a07] Apple AWT Startup Exception : _createMenuRef called with existing principal MenuRef already associated with menu 2010-03-05 02:28:25.318 java[1315:a07] Apple AWT Restarting Native Event Thread The SWT window closes and then the app hangs, with no windows open. It looks like the SWT app doesn't shut down cleanly and leaves it's menu entries associated with it, which prevents the LWJGL window from opening. Mac OS X only wants one application menu. SWT doesn't free it's own menu and LWJGL wants to add another. Facts: A button in the SWT dialog is supposed to close the dialog and open a LWJGL window (org.lwjgl.opengl.Display). The button sets a static variable in the app to tell it what to do next after the SWT window is closed, so the LWJGL window is NOT being opened from a SWT callback directly. The button then closes the SWT window. I don't know the correct way of doing this but tried various combinations of shell.close, shell.dispose, display.close and display.dispose, none of them worked. They all close the window but the error occurs every time. Does anyone know what could be done to make this work?

  • Best practice: git, github, lighthouse and 2 developers

    - by Alxandr
    I'm setting up a new project and plan on using git and github for sourcecontroll and hosting of repo and lighthouse for bugtracking. I've been working with git for some while now, but only been using it for more of a backup solution than collaborate coding solution. Also, I've noticed that in github you can setup a servicehook to lighthouse so that whenever you push to github it notifies lighthouse of the changes. This uses a token for user-authentication and has the ability to change tickets to resolved etc. However, this token I believe functions that way so that whenever a user pushes to the repo (dosn't matter who), it's the owner of the repo that "updates" to lighthouse. This is a problem. So, I believe it is necessary with 2 separate repos at github (one for each dev), and I'm wondering about the workflow that should be used. Any1 care to shred any light on this matter? Like when to pull and push (and where), and how to make the two github repos in sync or something like that? Or another solution to the problem altogether.

  • How can an iPhone access another non-iPhone device over wireless or bluetooth?

    - by Tai Squared
    I'm trying to figure out if an iPhone can connect to another non-iPhone device over wireless or bluetooth and have seen conflicting information. Much of what I've found was before version 3.0 of the SDK came out, when it certainly wasn't possible. Looking at questions like this mention you can't connect to an arbitrary device unless if it's part of the "Works for iPhone" device. Do I need hardware that is part of this program? Looking through the Apple documentation, it mentions connecting two iPhones, not an iPhone to another Bluetooth device. Then there are articles like this that includes this quote ...and with the newly-announced "standard support" should allow file transfer between the iPhone and a computer, as well as between nearby iPhones Other questions mention Bonjour, and the Apple documentation talk about connecting to Bonjour devices, but can an iPhone connect to any Bonjour device? Does it have to have a wifi connection, or can it use Bluetooth? Even if I could use Bluetooth to connect to another device, it won't be available on first generation iPhones and iTouches, I believe. Is that correct? I'm thinking of an iPhone application that would need to communicate with other non-iPhone devices in the area, probably using Bluetooth, but possibly a direct wireless connection. What are the possibilities and limitations of this approach? Is it not possible to have an iPhone connect to an arbitrary Bluetooth device? Does the other device have to be on a wireless Bonjour network that? I'm trying to figure out if it's even possible for this to work or if it's not worth the effort.

  • Leopard => Snow Leopard architecture woes with nokogiri / rails

  • Java 1.5 crypto on OS X - AccessControlException

  • Cannot find interface declaration for 'UIResponder'

    - by lfe-eo
    Hi all, I am running into this issue when trying to compile code for an iPhone app that I inherited from a previous developer. I've poked around on a couple forums and it seems like the culprit may be a circular #import somewhere. First - Is there any easy way to find if this is the case/find what files the loop is in? Second - Its definitely possible this isn't the problem. This is the full error (truncated file paths so its easier to view here): In file included from [...]/Frameworks/UIKit.framework/Headers/UIView.h:9, from [...]/Frameworks/UIKit.framework/Headers/UIActivityIndicatorView.h:8, from [...]/Frameworks/UIKit.framework/Headers/UIKit.h:11, from /Users/wbs/Documents/EINetIPhone/EINetIPhone_Prefix.pch:13: [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:15: error: expected ')' before 'UIResponder' [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:17: error: expected '{' before '-' token [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:42: warning: '@end' must appear in an @implementation context [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:51: error: expected ':' before ';' token [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:58: error: cannot find interface declaration for 'UIResponder' As you can see, there are other errors alongside this one. These seem to be simple syntax errors, however, they appear in one of Apple's UIKit files (not my own) so I am seriously doubting that Apple's code is truly producing these errors. I'm stumped as to how to solve this issue. If anyone has any ideas of things I could try or ways/places I could get more info on the problem, I'd really appreciate it. I'm very new to Obj-C and iPhone coding.

  • UIWebView not loading URL

    - by jerincbus
    I'm having trouble getting a UIWebView to load a URL that I'm sending to it. Before I get into my code I was wondering if URL has to start with "http://" or can it start with "www."? I'm using an IBAction to push a UIView on to the stack: (IBAction)goToWebView { WebViewController *webController = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:[NSBundle mainBundle]]; //set the strings webController.webTitle = [self Title]; webController.webURL = [self website]; //Push the new view on the stack [[self navigationController] pushViewController:webController animated:YES]; [webController release]; webController = nil; } Then here is my WebViewController.h file: @interface WebViewController : UIViewController { IBOutlet UIWebView *webView; NSString *webTitle; NSString *webURL; } @property (nonatomic, retain) IBOutlet UIWebView *webView; @property (nonatomic, retain) NSString *webTitle; @property (nonatomic, retain) NSString *webURL; here And my WebViewController.m file: - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = webURL; //Create a URL object.

  • iPhone: Fastest way to create a binary Plist with simple key/value strings

    - by randombits
    What's the best way to create a binary plist on the iPhone with simple string based key/value pairs? I need to create a plist with a list of recipe and ingredients. I then want to be able to read this into an NSDictionary so I can do something like NSString *ingredients = [recipes objectForKey:@"apple pie"]; I'm reading in an XML data file through an HTTP request and want to parse all of the key value pairs into the plist. The XML might look something like: <recipes> <recipe> <name>apple pie</name> <ingredients>apples and pie</ingredients> </recipe> <recipe> <name>cereal</name> <ingredients>milk and some other ingredients</ingredients> </recipe> </recipes> Ideally, I'll be able to write this to a plist at runtime, and then be able to read it and turn it into an NSDictionary later at runtime as well.

  • Cocoa Bindings and Application Preferences - Crash

    - by iaefai
    Using the document provided by Apple to create an application preferences window that doesn't require any extra code, I seem to have triggered a crash that cannot be traced by me. While the stuff from Apple is older, I believe I have the settings pretty much the same as shown here: When I run my application (Hcode) and go to the preferences menu item, it brings up the proper window with the defaults I specified in the bindings with the exception of the Spaces per tab is blank (no idea how to fix this). When the window is closed, the application crashes with a backtrace similar to this: (gdb) bt #0 0x00007fff800cb1d4 in objc_msgSend_vtable5 () #1 0x00007fff80447cf3 in -[NSMenu _enableItem:] () #2 0x00007fff80447ad8 in -[NSCarbonMenuImpl _carbonUpdateStatusEvent:handlerCallRef:] () #3 0x00007fff8042b3b0 in NSSLMMenuEventHandler () #4 0x00007fff80e06b57 in DispatchEventToHandlers () #5 0x00007fff80e060a6 in SendEventToEventTargetInternal () #6 0x00007fff80e23d85 in SendEventToEventTarget () #7 0x00007fff80e52e61 in SendHICommandEvent () #8 0x00007fff80e66357 in UpdateHICommandStatusWithCachedEvent () #9 0x00007fff80e02a6d in HIApplication::EventHandler () #10 0x00007fff80e06b57 in DispatchEventToHandlers () #11 0x00007fff80e060a6 in SendEventToEventTargetInternal () #12 0x00007fff80e23d85 in SendEventToEventTarget () #13 0x00007fff80e6599b in SendMenuOpening () #14 0x00007fff80e65388 in DrawTheMenu () #15 0x00007fff80e65149 in MenuChanged () #16 0x00007fff80e643d4 in TrackMenuCommon () #17 0x00007fff80e60dbe in MenuSelectCore () #18 0x00007fff80e60596 in _HandleMenuSelection2 () #19 0x00007fff802fc3b9 in _NSHandleCarbonMenuEvent () #20 0x00007fff802cfeda in _DPSNextEvent () #21 0x00007fff802cf379 in -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] () #22 0x00007fff8029505b in -[NSApplication run] () #23 0x00007fff8028dd7c in NSApplicationMain () #24 0x0000000100001cac in main (argc=1, argv=0x7fff5fbff5e0) at /Users/iaefai/Projects/Hcode/Source/main.m:13 I am at a complete loss as to what the problem is.

  • Is background tasks the solution for this problem?

    - by Trinca
    Hi. I need to develop an enterprise app that monitors the network traffic. Basically it detects if the user is in wi-fi or cellular data and save the amount of bytes was sent and received in a period of time. I saw an App at the AppStore that do exactly this job. Detecting wi-fi or cellular data is quite simple using the Reachability Sample provided by Apple. My problem is to keep monitoring the bytes sent and received while the app is in background. As it is an enterprise App, I used UIBackgroundModes "voip" to avoid the app to be terminated. I also installed the setKeepAliveTimeout method and I'm able to see the logs each 10 minutes, BUT only for 10 seconds after the method runs. I mean, setKeepAliveTimeout brings my App to run a Timer for 10 seconds each 1o minutes. I'm thinking wether or not a task in background is the best solution for my problem. I'll appreciate any comments. EDIT: Ok guys. Thats the perfect way to do it. First of all you must read this: http://www.christian-fries.de/blog/files/tag-ios.html I tried this and it works really fine. All we need to do is to create a second thread detached from the main one. This way we have a continuos threading running forever. You must see the GCD docs at Apple's website also. Second thing you should consider for an enterprise App is to set it up as a voip App, this way iOS will put your App running even after a reboot. It's a special behavior iOS has to keep voip Apps running. Thats it guys. I hope it can help you.

  • - (void)keyboardWasShown not called when switching to another UITextField

    - by Shawn
    I'm having a strange problem that I don't understand. I have a UIScrollView with several UITextField objects. When I switch to the view, I set the first UITextField as firstresponder, and the keyboardWasShown method gets called due to the UIKeyboardDidShowNotification that the view is registered for. The weird thing is, when I touch the next UITextField, the keyboardWasShown method is not called. I don't understand this, since Apple's documentation says "If your interface has multiple text fields, the user can tap between them to edit the values in each one. When that happens, however, the keyboard does not disappear but the system does still generate UIKeyboardDidShowNotification notifications each time editing begins in a new text field." My code I've copied directly from Apple's documentation as well, and it works properly, but it only gets called the first time. What am I missing? - (void)registerForKeyboardNotifications { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:) name:UIKeyboardDidShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasHidden:) name:UIKeyboardDidHideNotification object:nil]; } - (void)keyboardWasShown:(NSNotification *)aNotification { //if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; CGSize kbSize = [[info objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue].size; CGRect bkgndRect = activeField.superview.frame; bkgndRect.size.height += kbSize.height; [activeField.superview setFrame:bkgndRect]; [scrollView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y) animated:YES]; keyboardShown = YES; UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; }

  • Most efficient way of creating tree from adjacency list

    - by Jeff Meatball Yang
    I have an adjacency list of objects (rows loaded from SQL database with the key and it's parent key) that I need to use to build an unordered tree. It's guaranteed to not have cycles. This is taking wayyy too long (processed only ~3K out of 870K nodes in about 5 minutes). Running on my workstation Core 2 Duo with plenty of RAM. Any ideas on how to make this faster? public class StampHierarchy { private StampNode _root; private SortedList<int, StampNode> _keyNodeIndex; // takes a list of nodes and builds a tree // starting at _root private void BuildHierarchy(List<StampNode> nodes) { Stack<StampNode> processor = new Stack<StampNode>(); _keyNodeIndex = new SortedList<int, StampNode>(nodes.Count); // find the root _root = nodes.Find(n => n.Parent == 0); // find children... processor.Push(_root); while (processor.Count != 0) { StampNode current = processor.Pop(); // keep a direct link to the node via the key _keyNodeIndex.Add(current.Key, current); // add children current.Children.AddRange(nodes.Where(n => n.Parent == current.Key)); // queue the children foreach (StampNode child in current.Children) { processor.Push(child); nodes.Remove(child); // thought this might help the Where above } } } } public class StampNode { // properties: int Key, int Parent, string Name, List<StampNode> Children }

  • Error handling in Rails Controller for adding embedded Mongoid documents to Model

    - by Dragonfly
    I have a Item model that has embedded documents. Currently, the following comments_controller code will add a comment to the item successfully. However, if pushing the comment document onto the comments array on item fails, I will not know this. #this does work, but i do not know if the push fails def create comment = Comment.new(:text => params[:text]) @item.comments << comment render :text => comment end I would like to have something like this, but @item.comments << comment does not return true or false: #this does not work def create comment = Comment.new(:text => params[:text]) if @item.comments << comment render :text => comment else render :text => 'oh no' end end Nor does it throw an exception when the document push fails: #this does not work def create begin comment = Comment.new(:text => params[:text]) @item.comments << comment render :text => comment rescue Exception => e render :text => 'oh no' end end Thanks!

  • EXC_BAD_ACCESS NSUrlConnection

    - by Lars
    Hi all, i got an EXC_BAD_ACCESS when i perform the last line of the function (webData). -(void)requestSoap{ NSString *requestUrl = @"http://www.website.com/webservice.php"; NSString *soapMessage = @"the soap message"; //website and soapmessage are valid in original code.
