Sorting Treeview created via UDF

[Armag3ddon]

Hi!

I try to sort a treeview with a sort function. I got a solution from the forum, it's here:

I copied _GUICtrlTreeView_Sort

Problem is, this only works when the treeview control was created using GUICtrlCreateTreeView like in Authenticity's example. I use a treeview that was created via _GUICtrlTreeView_Create. I can't figure out what the problem is resp. what I need to change.

Can anyone help?

I've attached Authenticity's example script, modified so it uses _GUICtrlTreeView_Create. I added ConsoleWrite in the _CompareFunc which shows what the problem is: Both ilParam and ilParam2 are 0 when the function is called.
