Subject: IE Automation/Recorder - Watir/Wet

Hi,
I am trying to write a Record and Playback utility for Watir and WET,
using Ruby and the OLE provision it provides.

My detailed knowledge about IE and DOM is limited though, I am using
the the code below to capture HTML events by extending the sample code
at the end of this email.

ev = WIN32OLE_EVENT.new(ie, 'HTMLElementEvents2')
ev.on_event {|*args| html_event_handler(*args)}

I am able to detect clicks on components , focus in /out etc. however I
am unable to successfully, detect "onchange".

I am particularly interested in capturing this change so that i can
determine when the user entered data in fields, comboboxes, text areas
etc.

Any takers ?
Thanks and Regards,
Asif



Sample code you will find relevant

$urls = []
def navigate(url)
  $urls << url
end

def stop_msg_loop
  puts "IE has exited..."
  throw :done
end

def default_handler(event, *args)
  case event
  when "BeforeNavigate"
    puts "Now Navigating to #{args[0]}..."
  end
end

ie = WIN32OLE.new('InternetExplorer.Application')
ie.visible = TRUE
ie.gohome
ev = WIN32OLE_EVENT.new(ie, 'DWebBrowserEvents')

ev.on_event {|*args| default_handler(*args)}
ev.on_event("NavigateComplete") {|url| navigate(url)}
ev.on_event("Quit") {|*args| stop_msg_loop}

catch(:done) {
  loop {
    WIN32OLE_EVENT.message_loop
  }
}


puts "You Navigated to the following URLs: "
$urls.each_with_index do |url, i|
  puts "(#{i+1}) #{url}"
end
