Blank Record Reading.

[ARPFre]

Good afternoon everyone,

I would like to know why not return the correct value?

Where am I going wrong in this simple function, even running as an administrator. And even copying the example from AutoIt Help.

Or if anyone has another idea how to get the username (and not the login) I would appreciate it.

Could you please teach me?

#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <MsgBoxConstants.au3>
#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 615, 437, 192, 124)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

;#RequireAdmin

Local $sFilePath = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI", "LastLoggedOnDisplayName")
MsgBox($MB_SYSTEMMODAL, "", "Result: " & $sFilePath)

;RegTests
;HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\SessionData\1
;or
;HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI

What does the error Flag return  ? :

MsgBox($MB_SYSTEMMODAL, "", "Error = " & @error & @CRLF & "Result: " & $sFilePath)

What happens, when you use the registrykey from the Help ? :

Local $sFilePath = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion", "ProgramFilesDir")

Since the key exists, I checked, including to not have a typo I copy the information.

Please use this MsgBox call. If RegRead does not return an error, then Error = 0 should appear there.

Yea! It also works, I would like to learn how it works.

Two ways to skin a cat today! Thank you!

It forces your script to run in 64 bits (instead of 32 bits which is the default), thus reading differently the registry.  Just like @Musashi did with a more explicit approach.
