Hi all,

below is my code  
def gotourl(url)  
begin  
$ie.goto(url)  
rescue Watir::Exception::NavigationException =\> e  
puts “navigation error”  
printscreen(url)  
end  
end

1.in IE 8.0 version i get this error message when i navigate to invalid  
URL “Internet Explorer cannot display the webpage”

my doubt is why rescue part is not executing for this error.

2.i want to know is it possible to use only “Watir::Exception” in my  
rescue portion some thing this like this.

def gotourl(url)  
begin  
$ie.goto(url)  
rescue Watir::Exception =\> e  
puts “navigation error”  
printscreen(url)  
end  
end

def clickbutton()  
begin  
$ie.button(:name,‘btnGs’).flash  
rescue Watir::Exception =\> e # instead of  
Watir::Exception::UnknownObjectException  
puts “object not found error”  
printscreen($ie.title)  
end  
end
