According to the MSDN Library (July 2001) it is possible to get the path of
the desktop wallpaper (in Win2K or later) using the SystemParametersInfo
function setting the SPI_GETDESKWALLPAPER constant as the uiAction (first)
parameter.
I tried to use that function but the compiler tells me that SPI_GETDESKWALLPAPER
is not defined and certainly it is is not declared in the Winuser.h file.
Can anyone please tell me the value of that constant so I can define it in
my project?

Thanks a lot!
