  • How to avoid that the robot gets trapped in local minimum?

    - by nesmoht
    Hi, I have some time occupying myself with motion planning for robots, and have for some time wanted to explore the possibility of improving the opportunities as "potential field" method offers. My challenge is to avoid that the robot gets trapped in "local minimum" when using the "potential field" method. Instead of using a "random walk" approach to avoid that the robot gets trapped I have thought about whether it is possible to implement a variation of A* which could act as a sort of guide for precisely to avoid that the robot gets trapped in "local minimum". Is there some of the experiences of this kind, or can refer to literature, which avoids local minimum in a more effective way than the one used in the "random walk" approach.

  • In QT 4.6 w/ Webkit: How to handle popup window requests (WebView::createWindow)?

    - by CM
    Hi all, I'm new to QT and have been trying to create a test browser. What I'm trying to do now is to handle js-based popup requests. After reading the QT documentation, I learned that I need to re-implement the QWebView::createWindow method to do just that. Now I've re-implemented this method, but it seems to be not called when I try to click a link that triggers a popup window. Can any one help me? Do I need to subclass both the WebView and WebPage classes? If so, how do I do that? I'm quite new to QT and I've done tons of searches and found nothing. Thank you all in advance for any hint and advice!

  • How to prompt for username and password entry in C# / SQL ASP.NET web app?

    - by salvationishere
    How do I prompt for username and password in my C#/SQL web application? This was developed in VS 2008 on a 32-bit XP. The current connection string I'm using in my web.config file is: <add name="AdventureWorksConnectionString2" connectionString="Data Source=SIDEKICK;Initial Catalog=AdventureWorks;Persist Security Info=false; " providerName="System.Data.SqlClient" /> When I select Basic Authentication it pops up the warning: "The authentication option you have chosen results in passwords being sent over the network without data encryption..." How do I choose this authentication method and still send passwords over securely? So essentially I am looking for the most secure authentication method but that still requires users to input password?

  • touchesEnded:withEvent: from UIScrollView First Responder

    - by Matthew Mitchell
    I've made a UIScrollView the first responder. I need to maintain touch events to a touchesEnded:withEvent: method on a view behind it. I've tried using the nextResponder method and that failed. I've tried forwarding touchesEnded:withEvent to the view behind it and that fails. How do I get this to work? The UIScrollView wont work unless it is the first responder or gets events some other way. Thank you for any help. Shame Apple's documentation and APIs are terrible in areas.

  • measuring a view before rendering it

    - by nourdine
    hello I need to find out how big a view will be after attaching it to its parent. I have overridden this method: onMeasure(int, int); but it looks like this method is invoked only when I actually add my custom view to it's container using: addView(myView); Do you think there is a way to get this information before rendering the view itself? Basically I need to know the actuall size before attaching it and not attach the view at all if it would take more certain amount of space. anybody?

  • Forcing LINQ to SQL to make one single call for all child rows

    - by zaph0d
    Let say I have a method (example taken from another post): public IQueryable<CityBlock> GetCityBlocks(){ var results = from o in db.city_blocks let buildings = GetBuildingsOnBlock(o.block_id) //returns Iqueryable select new CityBlock { BuildingsOnBlock = buildings, BlockOwner = o.block_owner }; return results; } In the calling method I add Skip() and Take() methods plus some filtering and then do a ToList(). The trouble is that I am getting dozens of database calls - one for all the city blocks and then a separate one for each building. Is there a way that I can refactor this code to just make two calls: one for the city blocks and one for all the buildings

  • How do I make my applet turn the user's input into an integer and compare it to the computer's random number?

    - by Kitteran
    I'm in beginning programming and I don't fully understand applets yet. However, (with some help from internet tutorials) I was able to create an applet that plays a game of guess with the user. The applet compiles fine, but when it runs, this error message appears: "Exception in thread "main" java.lang.NumberFormatException: For input string: "" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) at java.lang.Integer.parseInt(Integer.java:470) at java.lang.Integer.parseInt(Integer.java:499) at Guess.createUserInterface(Guess.java:101) at Guess.<init>(Guess.java:31) at Guess.main(Guess.java:129)" I've tried moving the "userguess = Integer.parseInt( t1.getText() );" on line 101 to multiple places, but I still get the same error. Can anyone tell me what I'm doing wrong? The Code: // Creates the game GUI. import javax.swing.*; import java.awt.*; import java.awt.event.*; public class Guess extends JFrame{ private JLabel userinputJLabel; private JLabel lowerboundsJLabel; private JLabel upperboundsJLabel; private JLabel computertalkJLabel; private JButton guessJButton; private JPanel guessJPanel; static int computernum; int userguess; static void declare() { computernum = (int) (100 * Math.random()) + 1; //random number picked (1-100) } // no-argument constructor public Guess() { createUserInterface(); } // create and position GUI components private void createUserInterface() { // get content pane and set its layout Container contentPane = getContentPane(); contentPane.setLayout( null ); contentPane.setBackground( Color.white ); // set up userinputJLabel userinputJLabel = new JLabel(); userinputJLabel.setText( "Enter Guess Here -->" ); userinputJLabel.setBounds( 0, 65, 120, 50 ); userinputJLabel.setHorizontalAlignment( JLabel.CENTER ); userinputJLabel.setBackground( Color.white ); userinputJLabel.setOpaque( true ); contentPane.add( userinputJLabel ); // set up lowerboundsJLabel lowerboundsJLabel = new JLabel(); lowerboundsJLabel.setText( "Lower Bounds Of Guess = 1" ); lowerboundsJLabel.setBounds( 0, 0, 170, 50 ); lowerboundsJLabel.setHorizontalAlignment( JLabel.CENTER ); lowerboundsJLabel.setBackground( Color.white ); lowerboundsJLabel.setOpaque( true ); contentPane.add( lowerboundsJLabel ); // set up upperboundsJLabel upperboundsJLabel = new JLabel(); upperboundsJLabel.setText( "Upper Bounds Of Guess = 100" ); upperboundsJLabel.setBounds( 250, 0, 170, 50 ); upperboundsJLabel.setHorizontalAlignment( JLabel.CENTER ); upperboundsJLabel.setBackground( Color.white ); upperboundsJLabel.setOpaque( true ); contentPane.add( upperboundsJLabel ); // set up computertalkJLabel computertalkJLabel = new JLabel(); computertalkJLabel.setText( "Computer Says:" ); computertalkJLabel.setBounds( 0, 130, 100, 50 ); //format (x, y, width, height) computertalkJLabel.setHorizontalAlignment( JLabel.CENTER ); computertalkJLabel.setBackground( Color.white ); computertalkJLabel.setOpaque( true ); contentPane.add( computertalkJLabel ); //Set up guess jbutton guessJButton = new JButton(); guessJButton.setText( "Enter" ); guessJButton.setBounds( 250, 78, 100, 30 ); contentPane.add( guessJButton ); guessJButton.addActionListener( new ActionListener() // anonymous inner class { // event handler called when Guess button is pressed public void actionPerformed( ActionEvent event ) { guessActionPerformed( event ); } } // end anonymous inner class ); // end call to addActionListener // set properties of application's window setTitle( "Guess Game" ); // set title bar text setSize( 500, 500 ); // set window size setVisible( true ); // display window //create text field TextField t1 = new TextField(); // Blank text field for user input t1.setBounds( 135, 78, 100, 30 ); contentPane.add( t1 ); userguess = Integer.parseInt( t1.getText() ); //create section for computertalk Label computertalkLabel = new Label(""); computertalkLabel.setBounds( 115, 130, 300, 50); contentPane.add( computertalkLabel ); } // Display computer reactions to user guess private void guessActionPerformed( ActionEvent event ) { if (userguess > computernum) //if statements (computer's reactions to user guess) computertalkJLabel.setText( "Computer Says: Too High" ); else if (userguess < computernum) computertalkJLabel.setText( "Computer Says: Too Low" ); else if (userguess == computernum) computertalkJLabel.setText( "Computer Says:You Win!" ); else computertalkJLabel.setText( "Computer Says: Error" ); } // end method oneJButtonActionPerformed // end method createUserInterface // main method public static void main( String args[] ) { Guess application = new Guess(); application.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); } // end method main } // end class Phone

  • Please explain class methods

    - by user1209902
    I'm finding it difficult to understand when it is necessary to create class methods. From what I've read, they are important for creating new objects, but I do not see how. The following class create a simple shape black rectangle. Can anyone show me how to incorporate a class method to do something that I could not do with an instance method? Shape.h #import <UIKit/UIKit.h> @interface Shape : UIView; - (id) initWithX: (int)xVal andY: (int)yVal; @end Shape.m #import "Shape.h" @implementation Shape - (id) initWithX:(int )xVal andY:(int)yVal { self = [super init]; UIView *shape = [[UIView alloc] initWithFrame:CGRectMake(xVal, yVal, 10, 10)]; shape.backgroundColor = [UIColor blackColor]; [self addSubview:shape]; return self; } @end

  • How can I know when SQL Full Text Index Population is finished?

    - by GarethOwen
    We are writing unit tests for our ASP.NET application that run against a test SQL Server database. That is, the ClassInitialize method creates a new database with test data, and the ClassCleanup deletes the database. We do this by running .bat scripts from code. The classes under test are given a connection string that connects to the unit test database rather than a production database. Our problem is, that the database contains a full text index, which needs to be fully populated with the test data in order for our tests to run as expected. As far as I can tell, the fulltext index is always populated in the background. I would like to be able to either: Create the full text index, fully populated, with a synchronous (transact-SQL?) statement, or Find out when the fulltext population is finished, is there a callback option, or can I ask repeatedly? My current solution is to force a delay at the end the class initialize method - 5 seconds seems to work - because I can't find anything in the documentation.

  • Data Validation for Random varying Phone Numbers

    - by baron
    I am storing phone numbers of varying lengths in my WPF (C#, VS 08) App. I store them as strings. My question is about my method AddNewPhoneNo(string phoneNo). In this method, I use Int.TryParse to validate the incoming number (i.e. not null, is numeric...). I've since realized this is probably not the best way to do this, because then I am limited to a number which is ± 2147483647. Definetly this is not always the case with phone numbers. What is a good, easy way to validate phone numbers? I guess the basic rules would be as follows: All numeric All positive Upto 25 chars (could be more, but this will to do for time being) Can't thing if theres any more rules at the moment, that's probably it.

  • How do you add < or > to a summary tag in Visual studio?

    - by Tony
    How do you add < (less than) or (greater than) to a summary comment in visual studio? I am in Visual Studio 2008. I have a generic method: public bool IsMemberProtected<T>(Expression<Func<T, object>> expression) Would love to have a summary tag of something like this /// <summary> /// Determines whether a member is protected. /// /// Usage: IsMemberProtected<ExampleType>(x => x.Member) /// </summary> But when I do that, the tooltip for the property no longer works when a developer hovers over the method in code to view the summary tag. Thoughts?

  • Printing python tkinter output

    - by Eric
    I am trying to print the contents of a python tkinter canvas. I have tried using the postscript method of canvas to create a postscript file, but I get a blank page. I know this is because I have embedded widgets, and these do not get rendered by the postscript method. Before I rewrite my program to create a more printer-friendly layout, can someone suggest a way to approach this problem? All of the programming books I have ever read approach the problem of sending output to a printer with a bit of hand-waving, something along the lines of: "It's a difficult problem that depends on interacting with the operating system." I also have a hard time finding resources about this because of all the pages related to printing to the screen. I am using Python 2.6, on Ubuntu 9.04.

  • Rails - How do you dynamically call the request methods "get put destroy etc" at runtime in tests

    - by adam
    I'm always writing tests to check my controller restricts people from certain actions depending on their status i.e. logged in, admin? etc Regardless of whether its a get to :index or a puts to :create the code is always the same. I'm trying to refactor this so that i have one method such as should_redirect_unauthenticated_to_login_action(request, action) and call it like so should_redirect_unauthenticated_to_login_action(:get, :index) = get :index But not sure how to dynamically call the various response methods rails provides for functional tests which seem to live in the module ActionController I mucked around with module = Kernel.const_get("ActionController") module::TestProcess.get NoMethodError: undefined method `get' for ActionController::TestProcess:Module can anyone help (im very new to dynamic calling in ruby)

    - by user469652
    I'm using entity framework model first development, and I need to do database migration often, The EF database generation power pack doesn't help a lot, because that data migration never worked here. The database migration here I mean, change the model, and then I can update the existing database from the model, but creating a new one. Is there any free of charge tool here invented here yet? Or would this going to be a new feature of next EF release? PS: I love django's ORM.
