Device manager not able to select root

[vikrams]

Hi All , 

I want to automate driver installation using device manager . I am able to get device manager windows pop up but i am not able to  select root tree item .

Please let me know  i am missing something given below code 

#Include <GuiTreeView.au3>

ShellExecute('devmgmt.msc')
WinWaitActive("Device Manager")
Global $hTree = ControlGetHandle("Device Manager", "", "[Class:SysTreeView32;Instance:1]")
MsgBox(0, "ControlGetHandle Example", "The control handle of Edit1 is: " & $hTree)
$hItem = _GUICtrlTreeView_FindItem($hTree, "Human Interface Device", True)
_GUICtrlTreeView_SelectItem($hTree, $hItem, $TVGN_CARET)
$next = _GUICtrlTreeView_GetNext($hTree, $hItem)
; Focus treeview and Send Enter
ControlFocus("Device Manager", "", $hTree)
ControlSend("Device Manager", "", $hItem, "{ENTER}")

Exit

Thanks and Regards,

Vikram

the way to automate such system-related tasks is rarely best handled by the GUI. have you tried DevCon?

Seems to work for me.  HID root is selected and next returns the handle for the next treeview item.

What are you trying to do with the tree view?  What do you expect to happen when you send "{Enter}"?

Also, I agree with Orbs suggestion.
