Code:

Copy      Help

SystemParametersInfo SPI_SETDESKWALLPAPER 0 _s.expandpath("$commonpictures$\Sample Pictures\Forest.jpg") 3 ;;change
5
SystemParametersInfo SPI_SETDESKWALLPAPER 0 "" 3 ;;remove
5
SystemParametersInfo SPI_SETDESKWALLPAPER 0 SETWALLPAPER_DEFAULT 3 ;;should restore default, but does not work on my computer


SPI_SETDESKWALLPAPER is 20
SETWALLPAPER_DEFAULT is -1

If gives 'unknown identifier' error (it may be in older QM versons), change these SPI_... constants to these values.

Works on all OS. (Edit: must be bmp file on XP).

ok iv done some looking around on the internet and i found that this code will only work with .bmp in xp, vista can use both .jpg and bmp

Code:

Copy      Help

str sPath  =  "C:\Users\Administrator\Pictures\Internet Explorer Wallpaper.bmp"

SystemParametersInfo SPI_SETDESKWALLPAPER 0 _s.expandpath(sPath) SPIF_UPDATEINIFILE|SPIF_SENDWININICHANGE

that seems to be what works best but in xp i cant use jpg how would i convert jpg or other image formats to bmp (with QM)?.

Try something like this:

Code:

Copy      Help

int b=LoadPictureFile(pathofjpgorgif 0)
SaveBitmap(b pathofbmp)
DeleteObject(b)

Or search the forum for gflax.
