  • recommendation systems and the cold start problem

    - by Hellnar
    Hello, I am curious what are the methods / approaches to overcome the "cold start" problem where when a new user or an item enters the system, due to lack of info about this new entity, making recommendation is a problem. I can think of doing some prediction based recommendation (like gender, nationality and so on). Thanks

  • Implementation of Nib project to Storyboard, Xcode

    - by Blake Loizides
    I have made a tabbed bar application in storyboard in xcode. I,m new to xcode. I got a Sample TableView XIB project from apple that I edited to my needs,The project has a UITableView that I Customized with Images, And with help of a certain forum member I was able to link up each image to a New View Controller. I tried to port or integrate My Nib Project Code to my StoryBoard Tabbed Bar Application.I thought I had everything right had to comment out a few things to get no errors, But the project only goes to a Blank Table View. Below are 2 links, 1 to my StoryBoard Tabbed Bar Application with the Table Code that I tried to integrate and the other My Successful Nib Project. Also is some code and pictures. If anybody has some free time and does not mind to help I would be extremely grateful for any input given. link1 - Storyboard link2 - XIB DecorsViewController_iPhone.m // // TableViewsViewController.m // TableViews // // Created by Axit Patel on 9/2/10. // Copyright Bayside High School 2010.

  • Service Layer which can switch between Web Service Layer and Data Access Layer

    - by Blake Blackwell
    I am building an application that will function as a client-server application, and also as a disconnected client application. I will be using WPF (browser app for client-server application). When interacting with the server's database, I will need to connect using WCF web services. When connecting with the localized database, I will need to connect using the local db's data access layer. What methods/patterns exist for this sort of architecture?

  • The Webbrowser DocumentComplited event wont fire c#

    - by Igal B.
    Hi. I have a problem using C# Webbrowser control. the problem is with the event DocumentComplited. Usually the event works fine. the problem is with this page:http://www.voiproblem.com/emulators/Netgear/WGR614v6/fw_forward.html when I (automatically) press on "add" the control navigates to:http://www.voiproblem.com/emulators/Netgear/WGR614v6/pforward.html. but it never firing the DocumentComplited event. I build a simple application that does the same and there it works fine. I mean when the app invokes InvokeMember("click") it does go to the DocumentComplited event. in my real app it doesnt. anyone can help me to figure it up what is the problem? thanks. <code> private void button1_Click(object sender, EventArgs e) { webBrowser1.Navigate("http://www.voiproblem.com/emulators/Netgear/WGR614v6/fw_forward.html"); } private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { HtmlElement elm = webBrowser1.Document.GetElementById("Add"); if (elm != null) webBrowser1.Document.GetElementById("Add").InvokeMember("click"); } </code>

  • Index out of bounds exception while iterating through a List<string>.

    - by Sergio Tapia
    I have a List of the location of images on a folder. I have five pictureBoxes that emulate a coverflow type area for users to skim through the images of a given folder. I know that the error is fired because the first image in the collection is set to the first picturebox, then if I click on cycleLeft(), there is a negative number. How can I account for this? For example, if the first image in the List is already set to the farthest left and someone clicks flip left, have that first image put on the last position of the list. Any guidance? private void leftArrow_Click(object sender, EventArgs e) { cycleImagesLeft(); } private void rightArrow_Click(object sender, EventArgs e) { cycleImagesRight(); } public void cycleImagesLeft() { //imageThree is the center image, that's why I use it as a frame of reference. int currentImage = pictures.IndexOf(imageThree.ImageLocation); imageOne.ImageLocation = pictures[currentImage - 3]; imageTwo.ImageLocation = pictures[currentImage - 2]; imageThree.ImageLocation = pictures[currentImage - 1]; imageFour.ImageLocation = pictures[currentImage]; imageFive.ImageLocation = pictures[currentImage + 1]; } public void cycleImagesRight() { int currentImage = pictures.IndexOf(imageThree.ImageLocation); imageOne.ImageLocation = pictures[currentImage - 1]; imageTwo.ImageLocation = pictures[currentImage]; imageThree.ImageLocation = pictures[currentImage + 1]; imageFour.ImageLocation = pictures[currentImage + 2]; imageFive.ImageLocation = pictures[currentImage + 3]; }

  • Problem in implementing IAlertUpdateHandler interface

    - by TheVillageIdiot
    I've implemented IAlertUpdateHandler interface in a class and used it for handling creation and updating of alerts. The code is fired but it goes into endless loop by calling itself again and again. Actually I want to suppress email notification so I'm calling a.Update(false); but this again calls PreUpdate or PostUpdate method and there is StackOverFlowException :( I've tried returning true/false from both the methods but nothing is helping.

  • Sending email via GMail in .NET

    - by VP
    I am getting the following error when I try to send an email in my C# program. I am using Visual Studio 2008 on windows 7. I would paste my code first and then the error: class email_log_files { private string login_username = "my_gmail_id"; private string login_password = "my_gmail_password"; public void send_email() { string src_address = "[email protected]"; string dest_address = "[email protected]"; try { MailMessage email_msg = new MailMessage(); SmtpClient email_client = new SmtpClient(); email_msg.From = new MailAddress(src_address); email_msg.Sender = new MailAddress(src_address); email_msg.ReplyTo = new MailAddress(src_address); email_msg.To.Add(dest_address); email_msg.Subject = "Test"; email_msg.Body = "Body of the message"; NetworkCredential credentials = new NetworkCredential(login_username, login_password); email_client.Credentials = credentials; email_client.Host = "smtp.gmail.com"; email_client.Port = 465; email_client.EnableSsl = true; email_client.Send(email_msg); Console.WriteLine("Message Sent Successfully!!"); Console.ReadLine(); } } } And the error message is as follows: The operation has timed out. Why is it always timing out? I am sure that I have the correct smtp server address and port number for gmail as I have configured my outlook with the same. Any help or ideas?

  • CF - How to get mouse position when ContextMenu pops up ??

    - by no9
    I have a problem i cannot solve. In my view (that shows a map) i created a contextMenu. When context menu is invoked i need to get the position where the user has clicked on the map. Here is my problem: In the view i already have onMouseDown event that gets me the coordinates where the user clicked. private void MapView_MouseDown(object sender, MouseEventArgs e) { this.lastMouseDownX = e.X; this.lastMouseDownY = e.Y; } When the contextMenu is invoked i need the same data, but the problem is that contextMenu only has EventArgs that dont keep the data i need. Furthermore ... contextMenu is invoked when user presses and holds mouse for a second and when its invoked the code does not enter onMouseDown event ! It just goes into popup event on my context menu.... I tried putting this in my popup event, but the coordinates are not ok. Y coordinate is way off the chart. private void servicesContextMenu_Popup(object sender, EventArgs e) { this.lastMouseUpX = Control.MousePosition.X; this.lastMouseUpX = Control.MousePosition.Y; } I also tried this, but with no success ... the problem remains ... when contextMenu is invoked the code does not fire onMouseDown event. http://www.mofeel.net/58-microsoft-public-dotnet-framework-compactframework/19285.aspx Help?

  • initWithCoder works, but init seems to be overwriting my objects properties?

    - by Zigrivers
    Hi guys, I've been trying to teach myself how to use the Archiving/Unarchiving methods of NSCoder, but I'm stumped. I have a Singleton class that I have defined with 8 NSInteger properties. I am trying to save this object to disk and then load from disk as needed. I've got the save part down and I have the load part down as well (according to NSLogs), but after my "initWithCoder:" method loads the object's properties appropriately, the "init" method runs and resets my object's properties back to zero. I'm probably missing something basic here, but would appreciate any help! My class methods for the Singleton class: + (Actor *)shareActorState { static Actor *actorState; @synchronized(self) { if (!actorState) { actorState = [[Actor alloc] init]; } } return actorState; } -(id)init { if (self = [super init]) { NSLog(@"New Init for Actor started...\nStrength: %d", self.strength); } return self; } -(id)initWithCoder:(NSCoder *)coder { if (self = [super init]) { strength = [coder decodeIntegerForKey:@"strength"]; dexterity = [coder decodeIntegerForKey:@"dexterity"]; stamina = [coder decodeIntegerForKey:@"stamina"]; will = [coder decodeIntegerForKey:@"will"]; intelligence = [coder decodeIntegerForKey:@"intelligence"]; agility = [coder decodeIntegerForKey:@"agility"]; aura = [coder decodeIntegerForKey:@"aura"]; eyesight = [coder decodeIntegerForKey:@"eyesight"]; NSLog(@"InitWithCoder executed....\nStrength: %d\nDexterity: %d", self.strength, self.dexterity); [self retain]; } return self; } -(void) encodeWithCoder:(NSCoder *)encoder { [encoder encodeInteger:strength forKey:@"strength"]; [encoder encodeInteger:dexterity forKey:@"dexterity"]; [encoder encodeInteger:stamina forKey:@"stamina"]; [encoder encodeInteger:will forKey:@"will"]; [encoder encodeInteger:intelligence forKey:@"intelligence"]; [encoder encodeInteger:agility forKey:@"agility"]; [encoder encodeInteger:aura forKey:@"aura"]; [encoder encodeInteger:eyesight forKey:@"eyesight"]; NSLog(@"encodeWithCoder executed...."); } -(void)dealloc { //My dealloc stuff goes here [super dealloc]; } I'm a noob when it comes to this stuff and have been trying to teach myself for the last month, so forgive anything obvious. Thanks for the help!

  • How do I write test code to exercise a C# generic Pair<TKey, TValue> ?

    - by Scott Davies
    Hi, I am reading through Jon Skeet's "C# in Depth", first edition (which is a great book). I'm in section 3.3.3, page 84, "Implementing Generics". Generics always confuse me, so I wrote some code to exercise the sample. The code provided is: using System; using System.Collections.Generic; public sealed class Pair<TFirst, TSecond> : IEquatable<Pair<TFirst, TSecond>> { private readonly TFirst first; private readonly TSecond second; public Pair(TFirst first, TSecond second) { this.first = first; this.second = second; } ...property getters... public bool Equals(Pair<TFirst, TSecond> other) { if (other == null) { return false; } return EqualityComparer<TFirst>.Default.Equals(this.First, other.First) && EqualityComparer<TSecond>.Default.Equals(this.Second, other.Second); } My code is: class MyClass { public static void Main (string[] args) { // Create new pair. Pair thePair = new Pair(new String("1"), new String("1")); // Compare a new pair to previous pair by generating a second pair. if (thePair.Equals(new Pair(new string("1"), new string("1")))) System.Console.WriteLine("Equal"); else System.Console.WriteLine("Not equal"); } } The compiler complains: "Using the generic type 'ManningListing36.Paie' requires 2 type argument(s) CS0305" What am I doing wrong ? Thanks, Scott

  • Best practice - When to evaluate conditionals of function execution

    - by Tesserex
    If I have a function called from a few places, and it requires some condition to be met for anything it does to execute, where should that condition be checked? In my case, it's for drawing - if the mouse button is held down, then execute the drawing logic (this is being done in the mouse movement handler for when you drag.) Option one says put it in the function so that it's guaranteed to be checked. Abstracted, if you will. public function Foo() { DoThing(); } private function DoThing() { if (!condition) return; // do stuff } The problem I have with this is that when reading the code of Foo, which may be far away from DoThing, it looks like a bug. The first thought is that the condition isn't being checked. Option two, then, is to check before calling. public function Foo() { if (condition) DoThing(); } This reads better, but now you have to worry about checking from everywhere you call it. Option three is to rename the function to be more descriptive. public function Foo() { DoThingOnlyIfCondition(); } private function DoThingOnlyIfCondition() { if (!condition) return; // do stuff } Is this the "correct" solution? Or is this going a bit too far? I feel like if everything were like this function names would start to duplicate their code. About this being subjective: of course it is, and there may not be a right answer, but I think it's still perfectly at home here. Getting advice from better programmers than I is the second best way to learn. Subjective questions are exactly the kind of thing Google can't answer.

  • How to Instantiate ObjectFrame in VB.NET

    I am trying to reach methods and properties of ObjectFrame through vb.net. But when I declared this as Dim objOLEObject As ObjectFrame and then trying to instantiate it as ObjOLEObject = New ObjectFrame it shows error like: "429: Retriveing the COM class factory for component with CLSID {3806e95d-e47c-11-cd-8701-00aa003f0f7} failed due to the following error: 80040154" To resolve this we re-installed both MS-Office 2003 and VS-2005, but could not get the solution. Could anyone suggest me how to declare and use this in vb.net? Thanks.

  • Having an issue with org.hibernate.SessionException: Session is closed! in Hibernate

    - by hal10001
    I've done quite a bit a research on this with no luck, but all the answers have a tendency to point toward the session context settings in the config file. What is odd is that I get a session connection the very first time I hit the page (and therefore, a successful result set), but then when I reload I get the following exception: org.hibernate.SessionException: Session is closed! Here are my config settings that are not DB connection string related: <property name="hibernate.show_sql">false</property> <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property> <property name="hibernate.current_session_context_class">thread</property> <property name="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</property> <property name="hibernate.cache.use_query_cache">false</property> <property name="hibernate.cache.use_minimal_puts">false</property> Here is an example of a call I make that produces the situation I described above. public T get(int id) { session.beginTransaction(); T type; try { type = getTypeClass().cast(session.get(getTypeClass(), id)); } catch (ClassCastException classCastException) { throw new ClassCastException(classCastException.getMessage()); } session.getTransaction().commit(); return type; } The session variable reference is to a static field that contains the current session. All of the session connection details are textbook reference manual. For example, here is my Hibernate session utility: import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; public class HibernateSessionFactoryUtil { private static final SessionFactory sessionFactory = buildSessionFactory(); private static SessionFactory buildSessionFactory() { try { return new Configuration().configure().buildSessionFactory(); } catch (Throwable ex) { System.err.println("Initial SessionFactory creation failed." + ex); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; } }
