  • Java keep printing a new line in my recursive method

    - by Abra Grace Libretto White
    I am trying to write a recursive method to print n number of asteriks in a line and create a new line at the end. So, TriangleOps.line(5); would print ***** This is the code I wrote: public static void line (int n){ if(n>0){ System.out.println("*"); line(n-1); }} instead it prints * * * * * with a lot of space at the end. Can anyone tell me how to remove the line breaks?

  • Test if a method is an override?

    - by Water Cooler v2
    Is there a way to tell if a method is an override? For e.g. public class Foo { public virtual void DoSomething() {} public virtual int GimmeIntPleez() { return 0; } } public class BabyFoo: Foo { public override int GimmeIntPleez() { return -1; } } Is it possible to reflect on BabyFoo and tell if GimmeIntPleez is an override?

  • Be notified of method calls in .NET

    - by Alex
    Basically, what I want to do is to be notified whenever a specific method has been called. I was hoping I could accomplish this using Reflection, but my attempts haven't gotten me anywhere yet, so I'm hoping that perhaps somebody else with the same need has accomplished this before and can enlighten me. I figured using MethodInfo was the way to go, but like I said, I found nothing there that could help me accomplish what I wanted to do. Any suggestions, hints or solutions would be greatly appreciated.

  • When To Use this.method()?

    - by Soo
    Hi SO, and happy Friday I have a question regarding the use of this.method();. My code seems to work without using the this., but I include it because it seems like the right thing to do. When should .this be used, and because it's presence doesn't always make a difference, what's the best practice for .this?

  • What is the difference between NavigationService.Navigate() method and PhoneApplicationFrame.Source

    - by afriza
    Taken from Exercise 1: Creating Windows Phone Applications with Microsoft Visual Studio 2010 Express for Windows Phone Task 3: Step 9 // navigate this.NavigationService.Navigate(new Uri("/PuzzlePage.xaml", UriKind.Relative)); Note: The PhoneApplicationPage class provides methods and properties to navigate to pages through its NavigationService property. You can call the Navigate method of the NavigationService and pass the URI for the page as a parameter. You can also use the GoBack and GoForward methods to navigate backward or forward in the navigation history. The hardware back button also provides backward navigation within an application. The event handler shown above uses the NavigationService to go to the PuzzlePage.xaml page. Task 4: Step 3 (RootVisual as Microsoft.Phone.Controls.PhoneApplicationFrame).Source = new Uri("/ErrorPage.xaml", UriKind.Relative); Note: ... Whenever you set the Source property to a value that is different from the displayed content, the frame navigates to the new content. ... What are the differences and similarities of both techniques?

  • jquery ajax method always returning an error?

    - by General_9
    I have the following ajax call and it always hits the error callback function every time it is called. The code in the handler is still run after the error but the success callback is never executed. What have I got wrong? $.ajax({ type: "POST", url: "Handlers/TheHandler.ashx", data: { control1: $('[id*=control1]').val(), control2: $('[id*=control2]').val(), control3: $('[id*=control3]').val(), control4: $('#control4').val(), control5: $('[id*=control5]').val(), control6: $('[id*=control6]').val() }, error: function (jqXHR, textStatus, errorThrown) { alert(jqXHR.readyState); alert(textStatus); alert(errorThrown); }, success: function (returnedValue) { alert("Got Here"); alert(returnedValue); } });

  • Equals method of System.Collections.Generic.List<T>...?

    - by Sambo
    I'm creating a class that derives from List... public class MyList : List<MyListItem> {} I've overridden Equals of MyListItem... public override bool Equals(object obj) { MyListItem li = obj as MyListItem; return (ID == li.ID); // ID is a property of MyListItem } I would like to have an Equals method in the MyList object too which will compare each item in the list, calling Equals() on each MyListItem object. It would be nice to simply call... MyList l1 = new MyList() { new MyListItem(1), new MyListItem(2) }; MyList l2 = new MyList() { new MyListItem(1), new MyListItem(2) }; if (l1 == l2) { ... } ...and have the comparisons of the list done by value. What's the best way...?

  • C# yield in nested method

    - by Fastidious
    If I step through the following code the call to ReturnOne() is skipped. static IEnumerable<int> OneThroughFive() { ReturnOne(); yield return 2; yield return 3; yield return 4; yield return 5; } static IEnumerator<int> ReturnOne() { yield return 1; } I can only assume that the compiler is stripping it out because what I'm doing is not valid. I'd like the ability to isolate my enumeration into various methods. Is this possible?

  • Constructing an object and calling a method without assignment in VB.Net

    - by mdryden
    I'm not entirely sure what to call what C# does, so I haven't had any luck searching for the VB.Net equivalent syntax (if it exists, which I suspect it probably doesn't). In c#, you can do this: public void DoSomething() { new MyHelper().DoIt(); // works just fine } But as far as I can tell, in VB.Net, you must assign the helper object to a local variable or you just get a syntax error: Public Sub DoSomething() New MyHelper().DoIt() ' won't compile End Sub Just one of those curiosity things I run into from day to day working on mixed language projects - often there is a VB.Net equivalent which uses less than obvious syntax. Anyone?
