  • Custom back button click event on pushed view controller

    - by TechFusion
    Hello, I have pushed view controller and load WebView and Custom rectangular rounded button on right down left corner into view using programmatic way. -(void)loadView { CGRect frame = CGRectMake(0.0, 0.0, 480, 320); WebView = [[[UIWebView alloc] initWithFrame:frame] autorelease]; WebView.backgroundColor = [UIColor whiteColor]; WebView.scalesPageToFit = YES; WebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleTopMargin); WebView.autoresizesSubviews = YES; WebView.exclusiveTouch = YES; WebView.clearsContextBeforeDrawing = YES; self.roundedButtonType = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain]; self.roundedButtonType.frame = CGRectMake(416.0, 270.0, 44, 19); [self.roundedButtonType setTitle:@"Back" forState:UIControlStateNormal]; self.roundedButtonType.backgroundColor = [UIColor grayColor]; [self.roundedButtonType addTarget:self action:@selector(back:) forControlEvents:UIControlEventTouchUpInside]; self.view = WebView; [self.view addSubview: self.roundedButtonType ]; [WebView release]; } This is action that I have added as back button of navigation. -(void)back:(id)sender{ [self.navigationController popViewControllerAnimated:YES]; } -(void)viewDidUnload{ self.WebView = nil; self.roundedButtonType = nil; } -(void)dealloc{ [roundedButtonType release]; [super dealloc]; } Here, When Back button click then it is showing previous view but application got stuck in that view and GDB shows Program received signal :EXC_BAD_ACCESS message. how resolve this issue? Thanks,

  • Why can't I build this Javascript object?

    - by Alex Mcp
    I have an object I'm trying to populate from another object (that is, iterate over a return object to produce an object with only selected values from the original). My code looks like this: var collect = {}; function getHistoricalData(username){ $.getJSON("http://url/" + username + ".json?params", function(data){ for (var i=0; i < data.length; i++) { console.log(i); collect = { i : {text : data[i].text}}; $("#wrap").append("<span>" + data[i].text + "</span><br />"); }; console.log(collect); }); } So I'm using Firebug for debugging, and here's what I know: The JSON object is intact console.log(i); is showing the numbers 1-20 as expected When I log the collect object at the end, it's structure is this: var collect = { i : {text : "the last iteration's text"}}; So the incrementer is "applying" to the data[i].text and returning the text value, but it's not doing what I expected, which is create a new member of the collect object; it's just overwriting collect.i 20 times and leaving me with the last value. Is there a different syntax I need to be using for assigning object members? I tried collect.i.text = and collect[i].text = and the error was that whatever I tried was undefined. I'd love to know what's going on here, so the more in-depth an explanation the better. Thanks!

  • Ruby on Rails: reducing complexity of parameters in a RESTFul HTTP POST request (multi-model)

    - by randombits
    I'm using cURL to test a RESTFul HTTP web service. The problem is I'm normally submitting a bunch of values normally like this: curl -d "firstname=bob&lastname=smith&age=25&from=kansas&someothermodelattr=val" -H "Content-Type: application/x-www-form-urlencoded" http://mysite/people.xml -i The problem with this is my controller will then have code like this: unless params[:firstname].nil? end unless params[:lastname].nil? end // FINALLY @person = People.new(params[:firstname], params[:lastname], params[:age], params[:from]) etc.. What's the best way to simplify this? My Person model has all the validations it needs. Is there a way (assuming the request has multi-model parameters) that I can just do: @person = People.new(params[:person]) and then the initializer can take care of the rest?

  • Build an unbound form in Acess 2007

    - by DoubleJ92
    I have an access application that has a form that allows the user to enter case notes. The main field of this form is tied to a SQL Server varchar(MAX) field in the source table. Since the users switched to Access 2007, their program keeps crashing when they are on the case notes form. As a possible solution to this problem, I would like to try unbinding this form and re-building it as an unbound form. This form needs to be able to add and update records into my SQL Server database. It also needs to be able to browse between records. I guess I am at a loss as to where to start. Any suggestions/code snippets is appreciated.

  • A better way to build this MySQL statement with subselects

    - by Corey Maass
    I have five tables in my database. Members, items, comments, votes and countries. I want to get 10 items. I want to get the count of comments and votes for each item. I also want the member that submitted each item, and the country they are from. After posting here and elsewhere, I started using subselects to get the counts, but this query is taking 10 seconds or more! SELECT `items_2`.*, (SELECT COUNT(*) FROM `comments` WHERE (comments.Script = items_2.Id) AND (comments.Active = 1)) AS `Comments`, (SELECT COUNT(votes.Member) FROM `votes` WHERE (votes.Script = items_2.Id) AND (votes.Active = 1)) AS `votes`, `countrys`.`Name` AS `Country` FROM `items` AS `items_2` INNER JOIN `members` ON items_2.Member=members.Id AND members.Active = 1 INNER JOIN `members` AS `members_2` ON items_2.Member=members.Id LEFT JOIN `countrys` ON countrys.Id = members.Country GROUP BY `items_2`.`Id` ORDER BY `Created` DESC LIMIT 10 My question is whether this is the right way to do this, if there's better way to write this statement OR if there's a whole different approach that will be better. Should I run the subselects separately and aggregate the information?

  • C# Simple Event Handler for Setting Alarm

    Why does the following line "alarm.AlarmEvent += new AlarmEventHandler(alarm_Sound);" gives me "An object reference is required for the non-static field, method, or property 'AlarmClock.Alarm.alarm_Sound(object, System.EventArgs)'" public static void Main(string[] args) { Alarm alarm = new Alarm(new DateTime(2010, 4, 7, 23, 2, 0)); alarm.Set(); alarm.AlarmEvent += new AlarmEventHandler(alarm_Sound); } Full source code here: Program.cs AlarmEventArgs

  • Is javac enough to build an OSGi bundle?

    - by Chatanga
    To produce a bundle from source using a tool such as javac, you need to provide it with a linear classpath. Unfortunately, it won't work in some situations still perfectly legal from an OSGi point of view: dependencies with embedded JAR in them; same packages contained by different dependencies. Since javac doesn't understand OSGi metadata, I won't be able to simply but the dependencies in a classpath. A finer package grained approach seems necessary. How this problem is addressed by people using OSGi in an automated process (continuous integration)? Strangely, there is a lot of resources on the web on how to create bundle JAR (creating the metadata, creating the JAR) provided you have the classes/inner JAR to put inside, but very few things on how actually get theses classes compiled.

  • WPF DependencyProperty event before content changed

    - by morsanu
    First I will explain the context of the problem, because you might be able to point me in a better direction. I need to implement a undo-redo like system on an object. The object has a series of dependency properties. Some are double, int, string but some are also of DependencyObject type. I need to save the value of the property before it is changed, and for this I added the CoerceValueCallback. public static readonly DependencyProperty MyBackgroundProperty = DependencyProperty.Register("MyBackground", typeof(MyCustomizableBackground), typeof(MyComponent), new UIPropertyMetadata(default(MyCustomizableBackground), null, new CoerceValueCallback(OnPropertyChanged))); In OnPropertyChanged I save the value before it's changed. MyCustomizableBackground is the DependencyObject that has also some dependency properties. The problem is that in this case, where I have a custom object as a property, the OnPropertyChanged method isn't triggered, but when I have a common type, it is triggered.

  • LinkButton not firing OnClick event in Accordion

    - by lampej
    I have not been able to get the break point I have on LinkButtonDelete_Click to fire. Is there a trick to dealing with buttons inside of Accordions?

  • IO Exception: directory name is invalid using directory from File System Watcher OnChanged Event

    - by Bi
    My C# application throws a System.IO.IOExcepton (The directory name is invalid) for the following code for implementing a filewatcher: public void OnChanged(object source, FileSystemEventArgs e) { DirectoryInfo dList = new DirectoryInfo(e.FullPath); FileInfo[] TxtFiles = dList.GetFiles("*.TXT"); } e.FullPath is "C:/Documents and Settings/Bi/Application Data/TestApp/Reports\\0MA01P62240_000005798_TRI_4947712701738551.TXT". If you notice it seems to append a "\\" to the path when it tracks the file. Any idea what the problem may be?

  • Idiomatic way to build a custom structure from XML zipper in Clojure

    - by Checkers
    Say, I'm parsing an RSS feed and want to extract a subset of information from it. (def feed (-> "http://..." clojure.zip/xml-zip clojure.xml/parse)) I can get links and titles separately: (xml-> feed :channel :item :link text) (xml-> feed :channel :item :title text) However I can't figure out the way to extract them at the same time without traversing the zipper more than once, e.g. (let [feed (-> "http://..." clojure.zip/xml-zip clojure.xml/parse)] (zipmap (xml-> feed :channel :item :link text) (xml-> feed :channel :item :title text))) ...or a variation of thereof, involving mapping multiple sequences to a function that incrementally builds a map with, say, assoc. Not only I have to traverse the sequence multiple times, the sequences also have separate states, so elements must be "aligned", so to speak. That is, in a more complex case than RSS, a sub-element may be missing in particular element, making one of sequences shorter by one (there are no gaps). So the result may actually be incorrect. Is there a better way or is it, in fact, the way you do it in Clojure?

  • How to build a programmer's wiki

    - by Llistes Sugra
    For years I've missed a wiki so everyone could describe the new tools programmed, the servers where they are running, svn information, the internal rules of programming, how-tos, code samples, etc. The wiki might be used for the dozen of programmers in the company and the externals. I've been using a pmwiki (easy install) and now I want a better approach. What wiki do you use? What plug-ins? Do you think there are better systems than wiki for this?
