Subject: Re: How to open file dialog in Ruby, and get open FileName? :-(

I find an example from http://www.java2s.com , but pop error:

main.rb:21:in `initialize': failed to create WIN32OLE object from 
`MSComDlg.CommonDialog' (WIN32OLERuntimeError)
    HRESULT error code:0x80040112


  cd = WIN32OLE.new("MSComDlg.CommonDialog")

  cd.filter = "All Files(*.*)|*.*" +"|Ruby Files(*.rb)|*.rb"
  cd.filterIndex = 2

  cd.maxFileSize = 128    # Set MaxFileSize
  cd.showOpen()
  file = cd.fileName      # Retrieve file, path

  if not file or file==""
    puts "No filename entered."
  else
    puts "The user selected: #{file}\n"
  end
