How to test a registry ValueName If exist

[coucou]

Hello,

I'm looking for how to test a registry ValueName If exist

$var = RegRead("HKEY_CURRENT_USER\Control Panel\Desktop", "PreferredUILanguages")
    If @error <> 0 Then ; registry ValueName exist
       MsgBox(4096, "SubKey #" & $var) ; display registry ValueName and ValueData

    Else ; registry ValueName NOT exist
      MsgBox(4096, "No Regsistry #" & $var)
   EndIf

I'll appreciate any help

Regards

$var = RegRead("HKCU\Control Panel\Desktop", "PreferredUILanguages")
    If @error = 0 Then ; registry ValueName exist
       MsgBox(4096, "" , "SubKey #" & $var) ; display registry ValueName and ValueData

    Else ; registry ValueName NOT exist
      MsgBox(4096, "" , "No Registry #")
   EndIf

You could use something like this:

$sValueName = "CaretWidth"
;$sValueName = "PreferredUILanguages"
$sValueData = RegRead("HKEY_CURRENT_USER\Control Panel\Desktop", $sValueName)
If @error = 0 Then ; registry ValueName exist
    MsgBox(4096, "", "ValueName: " & $sValueName & @CRLF & "ValueData: " & $sValueData & @CRLF & "ValueType: " & @extended) ; display registry ValueName, ValueData and ValueType
Else ; registry ValueName NOT exist
    MsgBox(4096, "", "ValueName: " & $sValueName & @CRLF & "does not exist")
EndIf

MsgBox(0, "_IsRegistryExist()", _IsRegistryExist("HKEY_CURRENT_USERControl PanelDesktop", "Test")) ; 0 = Doesn't Exist
MsgBox(0, "_IsRegistryExist()", _IsRegistryExist("HKEY_CURRENT_USERControl PanelDesktop", "CaretWidth")) ; 1 = Exists

Func _IsRegistryExist($sKeyName, $sValueName)
    RegRead($sKeyName, $sValueName)
    Return Number(@error = 0)
EndFunc   ;==>_IsRegistryExist
