I'm assuming I need to or in the ILC_MASK, but I'm not seeing clear doc on how to subsequently set the mask. Any insights would be appreciated.

CImageList lst;
// Using 32 bit icons
lst.Create(16, 16, ILC_COLOR32 | ILC_MASK, 0, 2);
// Using < 32 bit icons
lst.Create(16, 16, ILC_COLOR24 | ILC_MASK, 0, 2);
lst.Add(hIcon1);
lst.Add(hIcon2);

lst.Create(16, 16, ILC_COLOR32 | ILC_MASK, 0, 2);
lst.Add(&bmpImage, &bmpMask);

lst.Create(MAKEINTRESOURCE(IDB_MYBITMAP), 16, 2, RGB(0xFF, 0xFF, 0));

• ILC_COLOR24 for all image lists to which I intend to add different bitmaps and use a transparency color
  
• ILC_COLOR32 for all image lists for which I intend to add 32 bit icons, just to preserve the alpha channel
  
• ILC_COLORWhatever for static image lists - i.e., image lists which you feed ONE composite bitmap. Such a bitmap will have only one palette, and is therefore not subject to palette freakization.
