You will be able to see the icon only if you add some item to the list control.
Like

HIMAGELIST hList = ImageList_Create(32,32, ILC_COLOR8 |ILC_MASK , 8, 1);
m_cImageListNormal.Attach(hList);
CBitmap cBmp;
cBmp.LoadBitmap(IDB_IMAGES_NORMAL);
m_cImageListNormal.Add(&cBmp, RGB(255,255, 255));
cBmp.DeleteObject();
m_ListCtrl.SetImageList(&m_cImageListNormal, LVSIL_NORMAL);
m_ListCtrl.InsertItem(0,_T( "Test" ), 0 );

if you are not able to see the icon even after this, the problem can be the size of the bitmap IDB_IMAGES_NORMAL. change its size to exactly 32*32 or more than 32.
