Windows batch script to switch desktop background
提问by Tejen Shrestha
Is there a way to check what a user currently has as their background and then changing it depending on what it is? For example: I want a white background during day time and a black background for night time. Running the script would check the current background, if it is white it will switch to the black background, and if it is black it will switch to the white.
有没有办法检查用户当前的背景是什么，然后根据背景进行更改？例如：我想要白天的白色背景和晚上的黑色背景。运行脚本会检查当前背景，如果是白色则切换到黑色背景，如果是黑色则切换到白色。
I'm a little unfamiliar with Windows batch script and I'm seeking some tips and advice on how I can accomplish the task above. Here is what I've been able to find so far:
我对 Windows 批处理脚本有点不熟悉，我正在寻求一些关于如何完成上述任务的提示和建议。到目前为止，这是我能够找到的：
@echo off
call :quiet>nul 2>&1
goto :EOF
:quiet
:: Configure Wallpaper
REG ADD "HKCU\Control Panel\Desktop" /V Wallpaper /T REG_SZ /F /D "%SystemRoot%\energybliss.bmp"

You can use code like that:
你可以使用这样的代码：
@echo off
:: '>nul 2>&1' was moved to other place
call :quiet
exit /b
:quiet
:: Put there wallpaper name (with extension, bigger that 8 symbols)
set "Wallpaper.Night.BadWrited=Wallpaper1.bmp"
:: It is a dirty hack and example of bad code
for /F "tokens=*" %%a in ('reg query "HKCU\Control Panel\Desktop" /v Wallpaper') do set "Wallpaper.Current.BadWrited=%%a"
:: Take last 8 symbols of wallpaper name. Change number of symbols to your own minimal
set "Wallpaper.Current.BadWrited=%Wallpaper.Current.BadWrited:~-8%"
set "Wallpaper.Night.BadWrited=%Wallpaper.Night.BadWrited:~-8%"
if "%Wallpaper.Current.BadWrited%"=="%Wallpaper.Night.BadWrited%" (
call :MakeDayWallpaper>nul 2>&1
) else (
call :MakeNightWallpaper>nul 2>&1
)
exit /b
:MakeDayWallpaper
echo Day wallpaper setted
:: Put your code here
exit /b
:MakeNightWallpaper
echo Night wallpaper setted
:: Put your code here
exit /b
But i recommend to use the system scheduler. You can acces it from control panel, 'Scheduled Tasks' or something. You can make 2 files named 'makeday.bat' and 'makenight.bat'. Scheduler will run them every day at needed time
但我建议使用系统调度程序。您可以从控制面板、“计划任务”或其他方式访问它。您可以制作 2 个名为“makeday.bat”和“makenight.bat”的文件。调度程序将每天在需要的时间运行它们
