How to catch access denied error in windows command

The goal is to check if a user has started this bat file as an administrator, if not I echo the message.



I have this line of code in bat file:



echo 192.168.5.10 nsd-server >nul >> %WINDIR%System32DriversEtcHosts


It throws Access denied but when inspecting variable %errorlevel% it's always 0.
How to catch that error?
The solution has to be native, without any setup or installation because I need to run this on many client computers. When they run this file everything has to be completed, no extra steps.






command-line command windows-10

          I've found a solution. You need to use "||". If you use "|| rem" then variable %errorlevel% will contain error number.



            echo 192.168.5.10 nsd-server >nul >> %WINDIR%System32DriversEtcHosts || goto admin
          
echo 192.168.5.10 nsd-server >nul >> %WINDIR%System32DriversEtcHosts || rem

                    What visual should I use to simply compare current year value vs last year in Power BI desktop

                    Image
                    0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
