MsgBox(4096, "_RegReadEx", _
    StringFormat("Return @Error: %i\nReturn @Extended: %i\nReturn $Var: %s", @error, @extended, $Var))

Func _RegReadEx($sKeyName, $sValueName, $sDefault="")
    Local $sRet_Value = RegRead($sKeyName, $sValueName)
    If $sRet_Value = "" Then $sRet_Value = RegWrite($sKeyName, $sValueName, _RegGetExtendedType(@extended), $sDefault)

    Return SetError(@error, @extended, $sRet_Value)
EndFunc
