Hi,

I am new to ruby and hence need some help in defining a dynamic array.  
What I need to do is this:

1. I have 5 browsers open in my desktop.
2. I want to assign them browser id’s 1,2,3,4,5 (should be dynamic,  
since 5 browsers, so using 5 browser id’s). 1 way I thought was to use  
the window handle (hwnd) for each of the open browser.
3. So I used hwnd method and am storing it like @browserID = ie.hwnd.  
But I want the browserID to be a dynamic array which would increment  
everytime a new browser is open and will store the value of its window  
handle.

Can anyone help me create a dynamic array and store the hwnd to it as  
and when a browser is open? Even if you can help me with the basics of  
using a dynamic array, I would be satisfied.

Thanks,  
Anukul

ruby arrays are dynamic.

ff is a simple example. it just automatically stores 5 watir instances  
in the array. fr then on, you can access each instance or browser by  
just referencing the array…

a=[]  
#=\> []

5.times do  
a \<\< Watir::IE.new  
end  
#=\> 5

a.first.goto “[www.google.com](http://www.google.com)”  
#=\> 2.032

a.last.goto “[www.yahoo.com](http://www.yahoo.com)”  
#=\> 9.719

a.first.url\_list  
#=\> [“about:blank”, “[http://www.google.com.ph/](http://www.google.com.ph/)”]

a[1].url\_list  
#=\> [“about:blank”]

a.last.url\_list  
#=\> [“about:blank”, “[http://www.yahoo.com/](http://www.yahoo.com/)”]
