HI, this is what i did:

#define CAPS_WALLPAPER_BESTFIT 0
#define CAPS_WALLPAPER_STRETCH 1
#define CAPS_WALLPAPER_TILE 2

void CMainFrame::SetWallPaper ( int Style )
{
// Get window path and save image to the directory
char* Filepath = _T("C:\\Winnt\\ACD Wallpaper.bmp");

// Prepare the entry value
BYTE TileFlag[2] = {'0',0};
BYTE StyleFlag[2] = {'0',0};

if ( Style == CAPS_WALLPAPER_STRETCH )
StyleFlag[0] = '2';
if ( Style == CAPS_WALLPAPER_TILE )
TileFlag[0] = '1';

// Set the Wall Paper now
HKEY hKey;
if ( RegOpenKeyEx (HKEY_CURRENT_USER, "Control Panel\\Desktop", 0, KEY_ALL_ACCESS, &hKey)
== ERROR_SUCCESS )
{
LPCSTR EntryPath = "Wallpaper";
LPCSTR EntryTile = "TileWallpaper";
LPCSTR EntryStyle = "WallpaperStyle";

RegSetValueEx (hKey, EntryTile, 0, REG_SZ, TileFlag, 1);
RegSetValueEx (hKey, EntryStyle, 0, REG_SZ, StyleFlag, 1);
SystemParametersInfo (SPI_SETDESKWALLPAPER, 0, Filepath, SPIF_UPDATEINIFILE|SPIF_SENDWININICHANGE);

RegFlushKey (hKey);
RegCloseKey (hKey);
}
}

void CMainFrame::OnSetWallPaperBestFit()
{
SetWallPaper (CAPS_WALLPAPER_BESTFIT);
}

void CMainFrame::OnSetWallPaperStretch()
{
SetWallPaper (CAPS_WALLPAPER_STRETCH);
}

void CMainFrame::OnSetWallPaperTile()
{
SetWallPaper (CAPS_WALLPAPER_TILE);
}
