Question

有没有办法检查用户当前拥有的背景，然后根据具体情况进行更改？例如：我想在白天拍摄白色背景，在夜间拍摄黑色背景。运行脚本将检查当前背景，如果它是白色，它将切换到黑色背景，如果它是黑色，它将切换到白色。

我对Windows批处理脚本有点不熟悉，我正在寻求有关如何完成上述任务的一些提示和建议。这是我到目前为止所能找到的：

@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"
REG ADD "HKCU\Control Panel\Desktop" /V WallpaperStyle /T REG_SZ /F /D 0
REG ADD "HKCU\Control Panel\Desktop" /V TileWallpaper /T REG_SZ /F /D 2


:: Configure the screen saver.
:: REG ADD "HKCU\Control Panel\Desktop" /V SCRNSAVE.EXE /T REG_SZ /F /D "%SystemRoot%\System32\scrnsave.scr"
:: REG ADD "HKCU\Control Panel\Desktop" /V ScreenSaveActive /T REG_SZ /F /D 1


:: Set the time out to 900 seconds (15 minutes).
:: REG ADD "HKCU\Control Panel\Desktop" /V ScreenSaveTimeOut /T REG_SZ /F /D 900


:: Set the On resume, password protect box 
:: REG ADD "HKCU\Control Panel\Desktop" /V ScreenSaverIsSecure /T REG_SZ /F /D 1


:: Remove the user's ability to see the Screen Saver, background, and appearance tabs of Display Properties. 
::REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System" /V NoDispScrSavPage /T REG_DWORD /F /D 1
::REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System" /V NoDispBackgroundPage /T REG_DWORD /F /D 1
::REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System" /V NoDispAppearancePage /T REG_DWORD /F /D 1

:: Make the changes effective immediately

您可以使用以下代码：

@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”或其他内容访问它。你可以制作两个名为'makeday.bat'和'makenight.bat'的文件。调度程序将在每个需要的时间运行它们
