Simple script to change the MS Windows wallpaper from the command-line. Really just a wrapper around the SetSystemParametersInfo() API call, via Win32::API.
I'm using it as part of another small app. I'm writing (for my GF) to pick random papers. :)
#!/usr/bin/perl
use Win32::API;
use constant SPI_SETDESKWALLPAPER => 20;
use constant SPIF_UPDATEANDSENDINI => 3;
use constant NULL => 0;
my $syspinf = Win32::API->new('user32','SystemParametersInfo', [I,I,P,
+I], I)
or die "Could not import function.\n";
$syspinf->Call(SPI_SETDESKWALLPAPER, 0, $ARGV[0], SPIF_UPDATEANDSENDIN
+I);
