Geek.Menu Wallpaper switcher?

I did something similar:

dir /a-d | find /i /c "photo" > wallpaperfiles.txt
set /p count=<wallpaperfiles.txt
Set /a Number=(%Random% %%count%)+1
copy photo%Number%.bmp portableapps_wallpaper.bmp /Y

This means that I don't have to change the code if I add a new wallpaper file. As long as the wallpaper files are called photoX.bmp where X is a number and each file is number sequentially from 1 upwards, then the file selected will be totally random. I can add as many wallpapers I like and the one selected should be random.

I also found that by putting in:

rundll32.exe user32.dll,UpdatePerUserSystemParameters

to refresh the desktop background after the call to load StartPortableApps.exe meant that the new background image shows after loading PortableApps. Without it, the old background often remained.

Using XP SP3 and bat2exe to convert to an exe file. Your mileage may vary...
