How to make a GUICtrlCreateTreeView from a specific data?

[DannyJ]

Hello,

I have a specific data, and I am thinking how to make from this data a TreeView.

I would be grateful if you could me provide some hints or an algorithm.

The data looks like this:

Org/Unit1/Users
Org/Unit1/Computers
Org/Unit1/Computers/Wifi1
Org/Unit1/Computers/Wifi2
Org/Unit1/Computers/Guest/Wifi1
Org/Unit2/Company/Users
Org/Unit2/Company/Tables
Org/Unit2/Computers

Do you have any idea or hint how to make  a TreeView from this data?

Might not be the best way but it should do the trick.

Using recursive algorithm :
