What is wrong with my _GUICtrlTreeView_GetText() ?

[Exit]

The _GUICtrlTreeView_GetText() function returns an empty string.

#include <GuiTreeView.au3>
While WinClose("[class:MMCMainFrame]") ; close all device manager windows
WEnd
Run("mmc devmgmt.msc")
$winhandle = WinWaitActive("[class:MMCMainFrame]")
$hWnd = ControlGetHandle($winhandle, "", "[Class:SysTreeView32;Instance:1]")
ControlFocus($winhandle, "", $hWnd)
$hItem = _GUICtrlTreeView_GetFirstItem($hWnd)
While Sleep(50)
$text = _GUICtrlTreeView_GetText($hWnd, $hItem) ; <======= get text
ConsoleWrite($hItem & ">" & $text & "<" & @LF)   ; <======= show text
$hItem = _GUICtrlTreeView_GetNext($hWnd, $hItem)
If $hItem = 0 Then ExitLoop
_GUICtrlTreeView_SelectItem($hWnd, $hItem, $TVGN_CARET)
WEnd
Exit

Console output:

Where is the bug ?

You can do what you are asking for with command line. No need to interact with the MMC.

[Exit]

Please be more specific or give an example how to read the text entries of the devicemanagers treeview.

Thanks.

Thanks for the link. The information is new and valuable to me.

There are two programs mentioned.

1.) DevCon.exe

Not applicable since it needs a separate installation of WDK.

The users of my program have no installed copy of this program.

2.) PNPUtil.exe

Is 'out of the box'. No installation needed.

But does not show the text of the devicemanager treeview.

Back to my original question.

What is wrong with my code ? Why I get empty text strings?

The function _GUICtrlTreeView_GetText() returns @error=0 and @extended=0

Here a new version of the code with @error and @extended display included

and a messagebox to see results in compiled version.

#include <GuiTreeView.au3>
While WinClose("[class:MMCMainFrame]") ; close all device manager windows
WEnd
$t = ""
Run("mmc devmgmt.msc")
$winhandle = WinWaitActive("[class:MMCMainFrame]", "", 3)
$hWnd = ControlGetHandle($winhandle, "", "[Class:SysTreeView32;Instance:1]")
ControlFocus($winhandle, "", $hWnd)
$hItem = _GUICtrlTreeView_GetFirstItem($hWnd)
While Sleep(50)
$text = _GUICtrlTreeView_GetText($hWnd, $hItem) ; read the text
$t1 = @error & " " & @extended & " " & $hItem & ">" & $text & "<" & @LF
ConsoleWrite($t1) ; and show
$t &= $t1
$hItem = _GUICtrlTreeView_GetNext($hWnd, $hItem)
If $hItem = 0 Then ExitLoop
_GUICtrlTreeView_SelectItem($hWnd, $hItem, $TVGN_CARET) ; to show, that the items are correct. See the blue selection of text moving down.
WEnd
MsgBox(262144, " ", $t, 0)
Exit

Works fine for me if I use #RequireAdmin on Windows 7 x64. I get nothing if I don't run it as Admin though, it won't even run the device manager.

EDIT: BTW, you should check out DevManView from Nirsoft.

Thanks for your feedback.

DevManView is no option since my program will be used by other users who are not willing to install another software.

I compiled it with X64 and without #requireadmin

My system is WIN7 x64

Now, the text is shown.

DevManView doesn't need to be installed, and you can FileInstall it in the compiled exe, and if needed delete it as you exit the script.

[Exit]

I compiled my script on a Win7 x86 and it works there too.

Conclusion:

_GUICtrlTreeView_GetText() works ok in x86 mode on a x86 machine and in x64 mode on a x64 machine.

But not in x86 mode on a x64 machine.

I will fileinstall both exe's in a x86 wrapper exe.

No need to fileinstall DevManView.
