How to select string in AutoIT?

[oemript]

I would like to know on how to select the string after the fourth dot as shown below using AutoIT.

$Str = "abc.edf.hjk.fde1244.3d8rhfjdhsh8ceuehh"

How to select the string within $Str?

$Result = "3d8rhfjdhsh8ceuehh"

Does anyone have any suggestions?
Thanks in advance for any suggestions

@oemript dog ate your help file? Take a look at String Management in the help file and you'll see several ways, including StringInStr (you almost typed it verbatim in your post) and StringSplit, as well as more complex Regex entries.
