Hello
Is it possible to get user input by using an Input Box e.g
Does a file exists - my code is as follows ........
puts "The file you are looking for does exist" if File.exist?("c:/Phil.txt")
.... then maybe get a message box to give the answer
I would like to get the user to enter c:/Phil.txt - is this possible and how

Regards
Phil

try something like this

#puts the question
puts "Add a filename here:"

# read a line from the commandline
str1 = STDIN.gets

#test for file existence (write logic yourself)

#echo
puts "#{str1} does exist"

note that you can use the FileTest module for checking the existence of the file

#puts the question
puts "Add a filename here:"

# read a line from the commandline
str1 = STDIN.gets

#test for file existence
flag = FileTest::exists?(str1.strip)
#echo
if flag then
      puts "#{str1.strip} does exist"
else
      puts "#{str1.strip} does NOT exist"
end

cheers

When I run the code it opens a command screen and does not allow me to make an entry.

SciTE is for development by the way, is there a reason why you want to launch a program this way, other than for debugging?

Not really - I guess it's easier for me to cut and paste etc - and visually it looks easier on the eye.
