  • How can I write cocoa bindings as code instead of in the Interface Builder?

    - by johnjohndoe
    In my modell got an NSMutableArray that keeps track of a changing number of elements. In my view I got a NSTextField that shows the number of elements. The view gots unarchived from the nib file and alloc/inits the modell. Therefore it knowns about the modell and the contained array. I established the connection as follows. In the Interface Builder at the textfield I added a Cocoa Binding "path" like this: myModell.myArray.@count. By this I can access the count property (which is a must since the array itself does not change). The binding is based on key-value compliance which I established at the modell so the array can be accessed. But key-value compliance is not part of the questions. My question: How can I put the binding into the sourcecode and not writing it into the Interface Builder?

  • Forcing positive sign on double in .Net String.Format

    - by Max Yaffe
    Context: .Net, C# I want to print a complex number made from two doubles. The sign needs to show on the imaginary part. I'd like to use the default double formatting for each part to minimize the number of characters. I tried using String.Format("{0:+G;-G}{1:+G;-G}j", real, imaginary) but this ended up printing: "+G-Gj". Not quite what I wanted. Is there any way to do this using the G specifier or do I need to do a custom format which would sacrifice auto-switching the exponent, e.g. {1:+#.######e###;-#.######e###}j"

  • devise register confirmation

    - by mattherick
    hello! i have a user and an admin role in my project. i created my authentification with devise, really nice and goot tool for handling the authentification. in my admin role i don´t have any confirmation or something like that. it is really simple and doesn´t make problems. but in my user model i have following things: model: devise :database_authenticatable, :confirmable, :recoverable, :rememberable, :trackable, :validatable, :timeoutable, :registerable # Setup accessible (or protected) attributes for your model attr_accessible :email, :username, :prename, :surname, :phone, :street, :number, :location, :password, :password_confirmation and few validations, but they aren´t relevant this time. my migration looks like following one: class DeviseCreateUsers < ActiveRecord::Migration def self.up create_table(:users) do |t| t.database_authenticatable :null = false t.confirmable t.recoverable t.rememberable t.trackable t.timeoutable t.validateable t.string :username t.string :prename t.string :surname t.string :phone t.string :street t.integer :number t.string :location t.timestamps end add_index :users, :email, :unique => true add_index :users, :confirmation_token, :unique => true add_index :users, :reset_password_token, :unique => true add_index :users, :username, :unique => true add_index :users, :prename, :unique => false add_index :users, :surname, :unique => false add_index :users, :phone, :unique => false add_index :users, :street, :unique => false add_index :users, :number, :unique => false add_index :users, :location, :unique => false end def self.down drop_table :users end end into my route.rb I added following statements: map.devise_for :admins map.devise_for :users, :path_names = { :sign_up = "register", :sign_in = "login" } map.root :controller = "main" and now my problem.. if I register a new user, I fill in all my data in the register form and submit it. After that I get redirected to the controller main with the flash-notice "You have signed up successfully." And I am logged in. But I don´t want to be logged in, because I don´t have confirmed my new user account yet. If I open the console I see the last things in the logs and there I see the confirmation-mail and the text and all stuff, but I am already logged in... I can´t explain why, ... does somebody of you have an idea? If I copy out the confirmation-token from the logs and confirm my account, I can log in, but if I don´t confirm, I also can log in..

  • How to implement square root and exponentiation on arbitrary length numbers?

    - by tomp
    I'm working on new data type for arbitrary length numbers (only non-negative integers) and I got stuck at implementing square root and exponentiation functions (only for natural exponents). Please help. I store the arbitrary length number as a string, so all operations are made char by char. Please don't include advices to use different (existing) library or other way to store the number than string. It's meant to be a programming exercise, not a real-world application, so optimization and performance are not so necessary. If you include code in your answer, I would prefer it to be in either pseudo-code or in C++. The important thing is the algorithm, not the implementation itself. Thanks for the help.

  • How can I get jcifs to play nicely with apache axis

    - by Ben Hammond
    I need to connect Apache Axis 1.4 to a Webservice that uses NTLM authentication to restrict access to its operations. I'm expecting to use Samba Jcifs to handle the NTLM handshake. I found http://hc.apache.org/httpcomponents-client/ntlm.html which gives me fantastic directions for how to wire up HttpClient 4.0 with jcifs. Trouble is, Axis wants to use Http Client 3.0 and the two apis look very different. There are 2 possibilities that I can see Write an object for Axis that lets it plug into HttpClient 4. Figure out how to wire HttpClient 3.0 up with Samba Jcifs. Number 1. looks non-trivial, but possible Number 2. I cannot find any encouraging messages on the web describing how to do this. My question is: has anyone successfully connected samba jcifs with HttpClient 3.0 ? Has anyone already created an Axis HttpSender object that works with HttpClient 4 ? Is there some better alternative that I have not considered?

  • Avoiding Nested Blocks

    - by Helium3
    If there is a view controller that wants to execute a number of block based tasks one at a time, how can the control be given back to the view controller after a completion block has executed. Lets say ViewControllerOne wants to execute a number of tasks, each relying on the result of the previous one, how would this control be given back to the viewcontroller after each completion block has been executed? I started thinking about this and I was heading towards a deeply nested block pattern that will surely only cause confusion to whoever else reads or tests it. A task executes and the completion block returns the result or error which is needed by the next task, which has its own completion task, that the next task relies on and so forth. How can the control be managed in one place, the viewcontroller? Would the completion block just call the next function that handles the next task, using a pointer to the view controller?

  • Selecting items from events, as evenly spaced as possible

    - by Matt Warren
    If I have an event that happens 15 times a second (numbered 1 - 15), but I only want to process it 3 times I can choose [1], [6] and [11],. It's important that the events I process are as evenly spaced as possible and take into account wrap-around, i.e. the events are continuous 13, 14, 15, 1, 2, 3 etc. If I want 4 items the best I can do is [1], [5], [9] & [13]. Is there a general algorithm that will calculate which events I need to process given the total number of events (total) and the number to process (processAmount).

  • Hide other domains' menus from node edit form on a Drupal site using domain access

    - by monkeyninja
    I'm in the process of making some improvements to a live Drupal site that's using the Domain Access module to run a number of microsites. I'm trying to find a way of restricting the menus a user can post content to from the node edit screen. A user on one of the domains should only be able to post content to menus associated with that domain. Is there a simple way of achieving this? I'm guessing there are some hooks I could use, but so far I have been unable to identify them. I'd prefer not to have to install further modules to achieve this and to be able to add some code to the current site to alter the forms. The site is struggling with the large number of modules we've had to install on it already.

  • Log information inside a JUnit Suite

    - by Alex Marinescu
    I'm currently trying to write inside a log file the total number of failed tests from a JUnite Suite. My testsuite is defined as follows: @RunWith(Suite.class) @SuiteClasses({Class1.class, Class2.class etc.}) public class SimpleTestSuite {} I tried to define a rule which would increase the total number of errors when a test fails, but apparently my rule is never called. @Rule public MethodRule logWatchRule = new TestWatchman() { public void failed(Throwable e, FrameworkMethod method) { errors += 1; } public void succeeded(FrameworkMethod method) { } }; Any ideas on what I should to do to achieve this behaviour?

  • Multiple ports listed in SQL Server connection string

    - by BBlake
    I have a legacy VB6 app where the servername, databasename, username, etc are defined in an INI file, but the port number for the connection string (the default 1433) is hard coded in the app. It's being moved to a new sql server back end that runs off a different port number. I'm trying to avoid having to alter and recompile the application which entails signifigant retesting, documentation, etc. I tried altering the INI file so that for the new server I have put in: SERVERNAME\INSTANCE,NEWPORTNUMBER This effectively builds the connection with Data Source = SERVERNAME\INSTANCE,NEWPORTNUMBER,1433; This appears to work correctly as it connects to the database when I run the app. It appears to me that the ,1433 portion is being ignored. Is this a valid assumption or will this cause me some problem I'm not seeing here?

  • How to keep Hibernate mapping use under control as requirements grow

    - by David Plumpton
    I've worked on a number of Java web apps where persistence is via Hibernate, and we start off with some central class (e.g. an insurance application) without any time being spent considering how to break things up into manageable chunks. Over time as features are added we add more mappings (rates, clients, addresses, etc.) and then amount of time spent saving and loading an insurance object and everything it connects to grows. In particular you get close to a go-live date and performance testing with larger amounts of data in each table is starting to demonstrate that it's all too slow. Obviously there are a number of ways that we could attempt to partition things up, e.g. map only the client classes for the client CRUD screens, etc., which would have been better to get in place earlier rather than trying to work it in at the end of the dev cycle. I'm just wondering if there are recommendations about ways to handle/mitigate this.

  • Excel - Counting unique values that meet multiple criteria

    - by wotaskd
    I'm trying to use a function to count the number of unique cells in a spreadsheet that, at the same time, meet multiple criteria. Given the following example: A B C QUANT STORE# PRODUCT 1 75012 banana 5 orange 6 56089 orange 3 89247 orange 7 45321 orange 2 apple 4 45321 apple In the example above, I need to know how many unique stores with a valid STORE# have received oranges OR apples. In the case above, the result should be 3 (stores 56089, 89247 and 45321). This is how I started to try solving the problem: =SUM(IF(FREQUENCY(B2:B9,B2:B9)>0,1)) The above formula will yield the number of unique stores with a valid store#, but not just the ones that have received oranges or bananas. How can I add that extra criteria?

  • MooTools event listener disappears after element.innerHTML is changed

    - by acoder
    Hi everyone, I am trying to achieve this task using MooTools. Description: I attached an event listener to "myButton" link. A click on this link initiates an AJAX request and updates "myDiv" content based on the response text. During this request a POST variable is being sent to "button.php", but it's not used at the moment.. (i wish to use it later) OK, as a result, "myDiv" gets exactly the same link with the same ID (myButton) + a random number, so that we could see that each click generates a new number. The problem: After the first click on "myButton", "myDiv" updates correctly, showing a random number. When I click "myButton" for the second time (this time in newly updated div), the div does not refresh anymore. Please note that I need "myButton" to be inside "myDiv", and "myDiv" must be updated (refreshed) after each click without having to refresh the entire page. Can somebody show me how to achieve this task based on this simplified code example? index.html <html> <head> <script type="text/javascript" src="mootools-1.2.4-core-nc.js"></script> <script> window.addEvent('domready', function() { $('myButton').addEvent('click', function(e) { e.stop(); var myRequest = new Request({ method: 'post', url: 'button.php', data: { action : 'test' }, onRequest: function() { $('myDiv').innerHTML = '<img src="images/loading.gif" />'; }, onComplete: function(response) { $('myDiv').innerHTML = response; } }); myRequest.send(); $('myButton').removeEvent('click'); }); }); </script> </head> <body> <div id="myDiv"> <a id="myButton" href="#">Button</a> </div> </body> </html> button.php <a id="myButton" href="#">Button</a> clicked <?php echo rand(1,100); ?>

  • Adding files to the DPR file vs project paths in Delphi 2010

    - by Robert McCabe
    We are just migrating from D7 to D2010 and are having a debate about cleaning up the project paths. We have a number of directories with a large number of Pas files that are included on some project paths, but only a few of the files are actually used by any single project. One option is to eliminate the project paths completely and only have all used files in the dpr. The second option is to keep only the needed files in the dpr and have project paths to the directories for the rest of the files. Is there any argument for one option over the other?

  • Monitoring .NET ASP.NET Applications

    - by James Hollingworth
    I have a number of applications running on top of ASP.NET I want to monitor. The main things I care about are: Exceptions: We currently some custom code which will email us when an exception occurs. If the application is failing hard it will crash our outlook... I know (and use) elmah which partly solves the problem however it is still just a big table of exceptions with a pretty(ish) UI. I want something that makes sense of all of these exceptions (e.g. groups exceptions, alerts when new ones occur, tells me what the common ones are that I should fix, etc) Logging: We currently log to files which are then accessible via a shared folder which dev's grep & tail. Does anyone know of better ways of presenting this information. In an ideal world I want to associate it with exceptions. Performance: Request times, memory usage, cpu, etc. whatever stats I can get I'm guessing this is probably going to be solved by a number of tools, has anyone got any suggestions?

  • Hibernate: getting a record but it's being updated in the database?

    - by jack
    For some reason Hibernate seems to be keeping my session open and updating the object without me explicitely invoking a save/update/saveorupdate. I guess the session is staying open and it's beeing marked as dirty. However this is not the desired behaviour, so what's the cleanest way to fix this? The issue seems to occur because I store a phone number without formatting in the database but the getter of the object returns a formatted telephone number. My flow: go to a jsp = controller = service = dao DAO getter function if(userId != 0) { return (User)dbFactory.get(User.class, userId); } return null; The service just passes it to the controller and the controller puts te User object in the request scope. I display it on my JSP page using EL.

  • UIPickerView and empty core data array

    - by Mark
    I have a viewcontroller showing items from a core data entity. I also have a tableview listing records from the same entity. The table is editable, and the user could remove all the records. When this happens, the view controller holding the pickerview bombs because it's looking for records in an empty array. How to prevent this? I'm assuming I need to do something different at objectAtIndex:row... # pragma mark PickerView Section - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 1; // returns the number of columns to display. } - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { return [profiles count]; // returns the number of rows } - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { // Display the profiles we've fetched on the picker Profiles *prof = [profiles objectAtIndex:row]; return prof.profilename; } //If the user chooses from the pickerview - (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { selectedProfile = [[profiles objectAtIndex:row]valueForKey:@"profilename"]; }

  • How do I view how many concurrent long polling requests there are on my server?

    - by Pascal
    My host is Joyent. My host says I have 15 process limit and prstat -J shows those processes but that doesn't tell me how many long polling requests are currently being served. I could record it myself but that would add alot of performance overhead. I need to know when the server is at its long polling limits. I know this limit occurs far before the memory or CPU is used up. From experimentation, I've already verified that the number of long polls open is NOT equivalant to the number of processes running, probably because each process has multiple threads, each serving a request. thanks.

  • How to retrieve row count of one-to-many relation while also include original entity?

    - by kaa
    Say I have two entities Foo and Bar where Foo has-many Bar's, class Foo { int ImportantNumber { get; set; } IEnumerable<Bar> Bars { get; set; } } class FooDTO { Foo Foo { get; set; } int BarCount { get; set; } } How can I efficiently sum up the number of Bars per Foo in a DTO using a single query, preferrably only with the Criteria interface. I have tried any number of ways to get the original entity out of a query with ´SetProjection´ but no luck. The current theory is to do something like SELECT Foo.*, BarCounts.counts FROM Foo LEFT JOIN ( SELECT fooId, COUNT(*) as counts FROM Bar GROUP BY fooId ) AS BarCounts ON Foo.id=BarCounts.fooId but with Criterias, and I just can't seem to figure out how.

  • Sorting a list of variable length integers delimited by decimal points...

    - by brewerdc
    Hey guys, I'm in need of some help. I have a list of delimited integer values that I need to sort. An example: Typical (alpha?) sort: 1.1.32.22 11.2.4 2.1.3.4 2.11.23.1.2 2.3.7 3.12.3.5 Correct (numerical) sort: 1.1.32.22 2.1.3.4 2.3.7 2.11.23.1.2 3.12.3.5 11.2.4 I'm having trouble figuring out how to setup the algorithm to do such a sort with n number of decimal delimiters and m number of integer fields. Any ideas? This has to have been done before. Let me know if you need more information. Thanks a bunch! -Daniel

  • Is it possible to manipulate the format on a DataGridView that is bound to a Data Source?

    - by Jack Johnstone
    I´m using SQL Server 2005 and Visual Studio 2008, C#. In the data source (the SQL Server data table) I use the date format mm/dd/yyyy, however, in a forms overview (DataGridView) users would like to see a completely other format, with year, week number and day number of week (yyww,d). I´ve created an algorithm for this transformation, but can I populate the affected cells with yyww,d instead of mm/dd/yyyy? And in that case - how would I do it? I guess I need to do it after the cells are populated, but before they are shown. The generic question is - how do I manipulate the format of Data Source bound DataGridView cells.
