What's going on?! Subtraction works fine until I get to 0.1 - 0.1. I'm in visual c# 2008 using the nonoba.com API. Console.WriteLine("hit! " + Users[targetNum].character.health + " : " + player.character.profile.attackPower); Users[targetNum].character.health -= player.character.profile.attackPower; Console.WriteLine("health!

I used a backslash to continue a Ruby statement on the next line. print abc \ + def I added a space after the backslash, because I like to blow things up, and, sure enough, I got an error: unexpected $undefined, expecting $end I assume $undefined is a global variable that means anything the compiler sees that it doesn't recognize -...
Hi, I created a class with four methods. I inserted print statements into them, so I could see if they work properly. There is no problem with the first three. But when I call the fourth method nothing prints out. Strangely when I initiate debugger and move through the method step by step, the statements are called(and output printed). ...
I am trying to throw a (custom) ImportException from the method importUsers in class UserHelper. I can see in the debugger that the throw clause is executed, but the method, from which the importUsers method is called, never catches the exception. Here is the method, where the exception is thrown: public static AccessorValidator impor...
Quite often I run into items in the .NET framework that have little or no code examples on how to use the features. On other occasions, there are plenty of examples, but none of them seem to work as prescribed. Case in point: The System.Diagnostics.ConsoleTraceListener class. From everything I've read and every code example I've seen, ...

I'm trying to show a small loading image during a slow operation with jQuery and can't get it right. It's a BIG table with thousands of rows. When I check the "mostrarArticulosDeReferencia" checkbox it removes the "hidden" class from these rows. This operation takes a couple of seconds and I want to give some feedback. "loading" is a di...

Can anyone shed some insight onto why the following happens? irb(main):001:0> r = '1'..'30' => "1".."30" irb(main):002:0> r.each do |i| irb(main):003:1* puts "#{i} : #{r.include?(i)}" irb(main):004:1> end 1 : true 2 : true 3 : true 4 : false 5 : false 6 : false 7 : false 8 : false 9 : false 10 : true ...

The following modify method somehow modifies the whole @x array instead of just simply generating another element to be pushed later. How come? def modify i, s t = @x[-1] t[i] = t[i] + s t end @x = [ [10, 12] ] @x << modify(0, 1) puts @x Edited The following code have done the trick. Still I wonder if its possible to get rid o...

I call the div2.appendChild() method on child element of div1. It removes the child from div1 and appends it to div2. If I then try to appe...

On my ubuntu server I run the following command: python -c 'import os; os.kill(5555, 0)' This is done so that I can see if pid 5555 is running. From my understanding this should raise an OSError if the pid is not running. This is not raising an OSError for me which means it should be a running process. However when I run: ps aux |...

Hello, I am coding a batch file. Here is a sample: if exist rootsys.txt del rootsys.txt if %lang%==1 ( if %bit%==32 echo C:\Program Files\path\to\the dir>rootsys.txt if %bit%==64 echo C:\Program Files(x86)\path\to\the dir>rootsys.txt goto :waset ) This goes on for six times (so if %lang%==2 etc... to if %lang%==6.)

For some reason, whenever I run this program it exits at permute(permutater, length, lenth); . This doesn't happen whenever I comment out the line and the function doesn't even run. Any help? ...
Hi, If you have seen my previous questions, you'd already know I am a big nuby when it comes to Ruby. So, I discovered this website which is intended for C programming, but I thought whatever one can do in C, must be possible in Ruby (and more readable too). The challenge is to print out a bunch of numbers. I discovered this nifty met...
