ControlTreeView - GetItemCount returns 0

[cw86]

Hello,

I have an issue where I am attempting to get the item count from a SysTreeView32 control from an install wizard - see attached screenshot.

I have verified the correct handle is being returned by comparing the return value from ControlGetHandle vs the control handle displayed in the AutoIt v3 Window Info tool.

I have also tried using _GUICtrlTreeView_GetCount, which also returns 0.

 

$hTreeView=ControlGetHandle("VLC media player Setup","","[CLASS:SysTreeView32; INSTANCE:1;]")
MsgBox($MB_SYSTEMMODAL, "Title", ControlTreeView("VLC media player Setup","",$hTreeView,"GetItemCount"), 10)
MsgBox($MB_SYSTEMMODAL, "Title", _GUICtrlTreeView_GetCount($hTreeView), 10)

 

Any help would be greatly appreciated!
