Hi,
   I need to create a excel sheet(.xls or .xlsx).
My Code:

   if File.exists?("test.xls")
      puts "File EXISTS"
      -----my code----
    else
      File.open(fileToTest, File::WRONLY|File::CREAT|File::EXCL)
  puts "-------FILE CREATED--------"
        ----my code----
    end

It creates an excel file(test.xls), but when I try to open the file I
get an alert box as shown in the attachment.

I working on Windows 7, MS Office 2007

Thanks
