  • Who likes short shorts?

    - by kiwicptn
    I got $2 change instead of $3 today and that got me thinking about short for some reason. What can do (these days ;-p) with a variable of the short primitive type (16 bits signed)? Any good reason to keep them around?

  • variables in jasper report

    - by ed1t
    Is there a way I could declare a variable of type HashMap which would call some java method to populate the HashMap? I want to have a hashmap in a report so depending on what the value of a certain field is, I would like to get the full description of it from an Hashmap.

  • Globals are bad! But should I use them in this context?

    - by Matt
    Would setting the $link to my database be one thing that I should use a GLOBAL scope for? In my setting of (lots of functions)...it seems as though having only one variable that is in the global scope would be wise. I am currently using the functions to transfer it back and forth so that way I do not have it in the global scope. But it is a bit of a hindrance to my script. Please advise.

  • Python: Create a duplicate of an array

    - by Dan
    I have an double array alist[1][1]=-1 alist2=[] for x in xrange(10): alist2.append(alist[x]) alist2[1][1]=15 print alist[1][1] and I get 15. Clearly I'm passing a pointer rather than an actual variable... Is there an easy way to make a seperate double array (no shared pointers) without having to do a double for loop? Thanks, Dan

  • Does WF4 have the ability to search for instances?

    - by racingcow
    Hello, I have a WF4 workflow service deployed in AppFabric. Is there any built-in way to do a generic search across all currently active workflow instances? For example, "get me a list of all active instances that have variable x = 5"? If someone could point me in the right direction on this it would be much appreciated.

  • What's the best way to structure this Linq-to-Events Drag & Drop code?

    - by Rob Fonseca-Ensor
    I am trying to handle a drag & drop interaction, which involves mouse down, mouse move, and mouse up. Here is a simplified repro of my solution that: on mouse down, creates an ellipse and adds it to a canvas on mouse move, repositions the ellipse to follow the mouse on mouse up, changes the colour of the canvas so that it's obvious which one you're dragging. var mouseDown = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonDown"); var mouseUp = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonUp"); var mouseMove = Observable.FromEvent<MouseEventArgs>(canvas, "MouseMove"); Ellipse ellipse = null; var q = from start in mouseDown.Do(x => { // handle mousedown by creating a red ellipse, // adding it to the canvas at the right position ellipse = new Ellipse() { Width = 10, Height = 10, Fill = Brushes.Red }; Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); canvas.Children.Add(ellipse); }) from delta in mouseMove.Until(mouseUp.Do(x => { // handle mouse up by making the ellipse green ellipse.Fill = Brushes.Green; })) select delta; q.Subscribe(x => { // handle mouse move by repositioning ellipse Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); }); the XAML is simply <Canvas x:Name="canvas"/> There's a few things I don't like about this code, and I need help refactoring it :) First of all: the mousedown and mouseup callbacks are specified as side effects. If two subscriptions are made to q, they will happen twice. Second, the mouseup callback is specified before the mousemove callback. This makes it a bit hard to read. Thirdly, the reference to the ellipse seems to be in a silly place. If there's two subscriptions, that variable reference will get overwritten quite quickly. I'm sure that there should be some way we can leverage the let keyword to introduce a variable to the linq expression that will mean the correct ellipse reference is available to both the mouse move and mouse up handlers How would you write this code?

  • Card game in python

    - by matt1024
    What is the best way to store the cards and suits in python so that I can hold a reference to these values in another variable? For example, if I have a list called hand (cards in players hand), how could I hold values that could refer to the names of suits and values of specific cards, and how would these names and values of suits and cards be stored?

  • Need helping creating a loop in R. Have many similarly named variables I have to apply the same func

    - by user335897
    I am using a dataset w/variables that have very similar names. I have to apply the same functions to 13 variables at a time and I'm trying to shorten the code, instead of doing each variable individually. q01a.F=factor(q01a) q01b.F=factor(q01b) q01c.F=factor(q01c) q01d.F=factor(q01d) q01e.F=factor(q01e) q01f.F=factor(q01f) q01g.F=factor(q01g) q01h.F=factor(q01h) q01i.F=factor(q01i) q01j.F=factor(q01j) q01k.F=factor(q01k) q01l.F=factor(q01l) q01m.F=factor(q01m) Suggestions?

  • Passing local variables to Erlydtl block

    - by Justin
    Hi, I've got a block of erlydtl code which I use repeatedly and would like to abstract to some kind of block / partial template. The issue is that I need to pass the block a local variable. This is possible with Rails partial templates; it looks like it's possible with Django's blocks [albeit with some kind of Python hackery]; I'm wondering if it's possible with Erlydtl [Erlang implementation of Django templates] Ideas ? Thanks you.

  • How do I sort an array of Person Objects by using compareto()?

    - by Adam
    Here is my code: > import java.util.Scanner; import java.util.Arrays; /** This class tests the Person class. */ public class PersonDemo { public static void main(String[] args) { int count = 0; Scanner in = new Scanner(System.in); boolean more = false; Person first = null; Person last = null; while (more) { System.out.println( "Please enter the person's name or a blank line to quit"); String name = in.nextLine(); if (name.equals("")) more = false; else { Person p = new Person(name); //new person object created with inputted name Person[] people = new Person[10]; //new array of 10 person objects people[count] = p; //declare person object with index of variable count as the new person object first = people[count]; // I have no idea what to do here. This is where I'm stuck. last = people[count]; // I can't figure out what to do with this either. first.compareTo(p); //call compareTo method on first and new person object last.compareTo(p); //call compareTo method on last and new person object count++; // increase count variable } } System.out.println("First: " + first.toString()); System.out.println("Last: " + last.toString()); } } And the Person class: /** A person with a name. */ public class Person implements Comparable { /** * Constructs a Person with a name. * @param aName the person's name */ public Person(String aName) { name = aName; } public String getName() { return name; } @Override public int compareTo(Object otherObject) { Person other = (Person)otherObject; if (name.compareTo(other.name) < 0) return -1; if (name.compareTo(other.name) > 0) return 1; return 0; } /** Returns a string representation of the object. @return name of Person */ public String toString() { return "[name=" + name + "]"; } private String name; }

  • Tomcat on Windows

    - by andrew007
    Hi, I installed Tomcat 6.0.18 on Windows 2003 as a service. I try to set the CATALINA_OPTS environment variable but it seems to be ignored by Tomcat. Do I need to use the Tomcat Service Manager (procrun) instead? Is it normal that if I install Tomcat as a service it doesn't see the enviroment variables but it only wotks with procrun? THANKS

  • Fixing VBSCRIPT inaccurate mathematical results due to rounding

    - by jay
    Try running this in a .VBS file MsgBox(545.14-544.94) You get a neat little answer of 0.199999999999932! This rounding issue also occurs unfortunately in Sin(2 * pi) since VB can only ever see the (user defined) variable pi as accurate as 3.14159265358979. Is rounding it manually (and loosing accuracy) the only way to improve the result? What is the most effective way of dealing with this kind of problem?

  • How to ignore expired certificates from outside a Java application?

    - by Creepy Gnome
    We have a Java application that we need to ignore an expired self-signed cert, however we cannot modify the code to do this. I wondering if there was a System Property or environment variable that we could provide at start up that would allow us to have all expired cert's ignored for now, or even be more specific and provide externally the specific cert that we would like to have the expiration ignored. Anyone have any ideas that would work?
