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.

Tcl

load ./chilkat.dll

set success 0

set sb [new_CkStringBuilder]

# Load a file that contains this string:  0123456789ABCDEF
set success [CkStringBuilder_LoadFile $sb "qa_data/txt/remove_chars.txt" "utf-8"]

# Return "56789A" from the string.
# if removeFlag is 1, the returned string is also removed from the sb.
set removeFlag 1
set result [CkStringBuilder_getRange $sb 5 6 $removeFlag]

puts "$result"
puts [CkStringBuilder_getAsString $sb]

# Output is: 
# 
# 56789A
# 01234BCDE

delete_CkStringBuilder $sb
