o.k. - i suk with windows.

any clue how one would determine the path of, and exec IE5 in windoze? do i
need to assume, as in unix, that it should be in the path? does ENV[‘PATH’]
do the same thing? could i be any more clueless? :wink:

any links you windoze guys could suggest?

thanks!

If you just need to open an URL you can start #{url} and windows will fire
the default web browser (guess which?).

If you wanna go the COM route:

require ‘win32ole’
ie = WIN32OLE.new(‘InternetExplorer.Application’)
ie.visible = true
ie.navigate(‘http://ruby-lang.org’)

Otherwise, try:

start iexplore

(The start dealy is a little bit of magic … it’s not just in the path,
or at least not on my machine).

Why do you need to exec IE?

It is possible – there are some difficulties – to simply launch an HTML
file with Windows (NT/2000/XP at least) and that will launch the user’s
default web browser. (You can usually launch a .htm and get IE, and .html
will get the default.)

I did this very recently. You have to use:

#{ENV['COMSPEC']} /c #{s}

Where s is the path to the HTML file you wish to open.

(The start dealy is a little bit of magic … it’s not just in the path,
or at least not on my machine).

It’s a command internal to the command interpreter which gets
spawned by the backtick operator. This solution has the drawback
of launching a DOS console. A 3d possibility is the following:

require ‘Win32API’

SW_SHOWNORMAL = 1
mydoc = ‘index.html’

se = Win32API.new(
‘shell32’,
‘ShellExecute’,
[‘L’,‘P’,‘P’,‘P’,‘P’,‘L’],
‘L’ )

se.Call(0,‘open’,mydoc,0,0,SW_SHOWNORMAL)

This will launch the correct application associated with
“mydoc”, not just html.
