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.

Note
This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.
JavaScript
var success = false;

var sb = new CkStringBuilder();

// 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.
var removeFlag = true;
var result = sb.GetRange(5,6,removeFlag);

console.log(result);
console.log(sb.GetAsString());

// Output is: 
// 
// 56789A
// 01234BCDE
