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.

PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Sb
integer li_RemoveFlag
string ls_Result

li_Success = 0

loo_Sb = create oleobject
li_rc = loo_Sb.ConnectToNewObject("Chilkat.StringBuilder")
if li_rc < 0 then
    destroy loo_Sb
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// Load a file that contains this string:  0123456789ABCDEF
li_Success = loo_Sb.LoadFile("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.
li_RemoveFlag = 1
ls_Result = loo_Sb.GetRange(5,6,li_RemoveFlag)

Write-Debug ls_Result
Write-Debug loo_Sb.GetAsString()

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


destroy loo_Sb
