Take advantage of today's free time, post some practical P

I know this has been posted by someone else, but I have something different.

Mine can set jpg images as background, someone else has posted before that can set jpg images, but it requires DLL file support, but mine doesn't.

It seems to involve the problem that the system automatically converts jpg to bmp format. I hope those with knowledge can study out how the system automatically converts it.

"%userProfile%\Local Settings\Application Data\Microsoft\Wallpaper1.bmp"
This is the complete path of the current desktop background.

Test environment: XP SP2

::Copy to change desktop background.bat::

::Drag a BMP format image into P

@echo off

title Change desktop background

cd/d %~dp0

if /i %~x1==.BMP copy %1 "%userProfile%\Local Settings\Application Data\Microsoft\Wallpaper1.bmp"

echo Changing desktop background

Poor, no one is reading, bumping it myself.

::Can also prohibit changing the wallpaper through desktop properties

Personally, I think this is not good.

把你的两个批处理合并成一个不就行了吗

One use doesn't work. You need to wait for the system to successfully convert the image, otherwise it won't work.

Also, the system automatically converts jpg to bmp. Has anyone studied this? I can't figure it out. Is it using mspaint or shimgvw.dll?

I once used PNG to write to the registry, but the actual boot result might have a half-screen black screen phenomenon when loading the PNG wallpaper. Finally, it was found that all formats were finally converted to BMP format. So it's not troublesome to use BMP for all.
