No.
Add the following line on the top of your script:
Dir.pwd
This will show you in which working directory ruby was started from. 
Guessing from the screenshot I assume it will be C:\Program 
Files\Notepad++.
Since you did not specify the path of test.txt, ruby will try to open a 
file test.txt in that directory.
There are a couple of ways around:
a) Change the working directory before you start ruby. For example open 
a command prompt, enter "cd /d g:\docs\l_ruby", then run the script: 
"ruby analyzer.rb"
b) Change the working directory after you start ruby. Add a line before 
your "File.read...." line:
Dir.chdir("g:/docs/l_ruby")
That will change the working directory to the one that contains the 
test.txt file.
c) Figure out how to change the working directory that Notepad++ starts 
ruby in. I have no idea how to do this.
I hope this will get you back on the track again. I suggest you have a 
look at http://en.wikipedia.org/wiki/Working_directory to learn what a 
working directory is, if you don't know already. It's essential to know 
when writing scripts.
