Cannot enumerate reg keys

10 posts in this topic

#1 ·  Posted (edited)

I am trying to enumerate, and/or get a count of registry subkeys. I have never had this problem before, but I am unable to subkeys that are definitely there. I am starting my script so it is running elevated, but this makes no difference.

Here is the code that I am using to get the subkey count.

$rKey = _WinAPI_RegOpenKey($HKEY_LOCAL_MACHINE,"SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Userdata\S-1-5-18\Products")
$arrayRKEY = _WinAPI_RegQueryInfoKey($rKey)
If IsArray($arrayRKEY) Then
                _ArrayDisplay($arrayRKEY)
Else
                MsgBox(0,"","No array" & @CR & "Error: " & @error & @CR & "Extended Error: " & @extended)
EndIf

The problem seems to be with the registry path, and If I change the path to this:

$rKey = _WinAPI_RegOpenKey($HKEY_LOCAL_MACHINE,"SOFTWARE\Microsoft\Windows\CurrentVersion")

It works fine. 

I don't get why I cannot get the information from the path I want.

Attached is a screenshot proving that I have numerous subkeys.

has anyone else seen this, or have a way to fix it? 

Thanks,

Jeff

Have you tried it with RegEnumKey instead?

Local $sSubKey = "", $i = 1
While 1
    $sSubKey = RegEnumKey("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Userdata\S-1-5-18\Products", $i)
    If @error Then ExitLoop
    ConsoleWrite("SubKey #" & $i & " under HKLM\SOFTWARE: " & $sSubKey & @CRLF)
    $i += 1
WEnd

Thanks for your quick responses.

The built in Reg Functions were the first thing I tried, but I wasn't having success, so I started looking at the API functions.

BrewmanNH - Using the While loop with RegEnumKey was the first thing I tried, but I had no success. I just tried again with your code, but it still doesn't work.

I just tried rebooting my machine in case there was something causing the problem there, but that didn't help.

Would you please so kind to post a complete script.

Then we could try and see, where the error is.

I certainly could post all my code, but you're assuming there is something else wrong with the code , but that is not the case. This is the only piece of code that is failing. Here is all the code of a script I am using:

#include <WinAPIReg.au3>
#include <Array.au3>
Local $sHKLM_Inst = "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer"
Local $sHKLM_UnInst64 = "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall"
Local $sHKLM_UnInst = "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
$rKey = _WinAPI_RegOpenKey($HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Userdata\S-1-5-18\Products")
$arrayRKEY = _WinAPI_RegQueryInfoKey($rKey)
If IsArray($arrayRKEY) Then
    _ArrayDisplay($arrayRKEY)
Else
    MsgBox(0, "", "No array" & @CR & "Error: " & @error & @CR & "Extended Error: " & @extended)
EndIf
_WinAPI_RegCloseKey($rKey)
Local $sSubKey = "", $i = 1
While @error <> 0
    $sSubKey = RegEnumKey("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Userdata\S-1-5-18\Products", $i)
    MsgBox(0, "", "SubKey #" & $i & " under HKLM\SOFTWARE: " & $sSubKey & @CRLF)
    $i += 1
WEnd

I tried running a Reg Query from command line and this populates the subkeys fine... It's kind of a crappy way to get the information, but I may have to resort to exporting the keys from here. It seems like there is probably a configuration setting on my PC that isn't working. 

I am going to test this code on another box to see if that is also having problems reading back the registry keys to me.

Your While loop is wrong, @error will never happen so you're going to get stuck in it forever. Write it the way I wrote it and you'll be able to get out of the loop when you run out of keys to enumerate. BTW, my code as written works on my computer.

Exit. Thank you very much. The registry key I used was missing the 64... I am sure I didn't have to do that before. Oh well it's working now :-) Thanks very much
