Get a Substring by Char Index and Length

Demonstrates how to use the GetRange method to get a substring by index and length.

Note: This example demonstrates the GetRange method which was added in Chilkat v9.5.0.87.

Ruby

require 'chilkat'

success = false

sb = Chilkat::CkStringBuilder.new()

# Load a file that contains this string:  0123456789ABCDEF
success = sb.LoadFile("qa_data/txt/remove_chars.txt","utf-8")

# Return "56789A" from the string.
# if removeFlag is true, the returned string is also removed from the sb.
removeFlag = true
result = sb.getRange(5,6,removeFlag)

print result + "\n";
print sb.getAsString() + "\n";

# Output is: 
# 
# 56789A
# 01234BCDE
