Windows批处理脚本切换桌面背景 [英] Windows batch script to switch desktop background

问题描述

是否可以检查用户当前的背景，然后根据背景进行更改?例如:我希望白天使用白色背景，而夜间使用黑色背景.运行脚本会检查当前背景，如果是白色，它将切换为黑色背景，如果是黑色，则将切换为白色.

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.

我对Windows批处理脚本有点不熟悉，我正在寻找一些有关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:

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:

@echo off
call :quiet>nul 2>&1
goto :EOF

:quiet

REG ADD "HKCU\Control Panel\Desktop" /V Wallpaper /T REG_SZ /F /D "%SystemRoot%\energybliss.bmp"

推荐答案

您可以使用如下代码:

@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

但是我建议使用系统调度程序.您可以从控制面板，计划任务"等访问它.您可以制作两个名为"makeday.bat"和"makenight.bat"的文件. Scheduler会在需要的时间每天运行它们

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
