user: handle special cases for SPI_SETDESKWALLPAPER
The special cases remove the wallpaper or set it to default.
Previously, these cases were ignored, so Wine would crash.
-if (filename == (LPSTR)-1)
+if ((LPCSTR)SETWALLPAPER_DEFAULT == filename || (LPCSTR)NULL ==
filename || '\0' == filename[0])
{
-GetProfileStringA( desktop, WallPaper, (None), buffer, 256 );
-filename = buffer;
+ /* set default wallpaper or remove wallpaper*/
+ if (hbitmapWallPaper)
+ DeleteObject( hbitmapWallPaper );
+ return TRUE;
}
hdc = GetDC( 0 );
According to MSDN, if
- pvParam==SETWALLPAPER_DEFAUL || pvParam==NULL, then wallpaper will be
set to default one
- pvParam[0]=='\0', then wallpaper will be removed.
I cannot see any signs of such distinction in your code :)
When I ran the unit test on Windows 2000, that's what it did: in all
three cases (SETWALLPAPER_DEFAULT, NULL, or '\0'), Windows 2000 removed
the wallpaper. So, it seems the default wallpaper is no wallpaper, and
a test could be added to show that. (I already have a test that checks
the default wallpaper is the same on both SETWALLPAPER_DEFAULT and NULL).
Beyond the cosmetics of changing the wallpaper, the purpose of the new
code is to keep Wine from crashing on SETWALLPAPER_DEFAULT.
