When you set the image list of a tree you are giving it images to use next
to each item. When you add items to the tree you can tell it which image in
the image list to use by passing it the index of the image.

So there won't be any images until you add items to the tree control.

Your image list does not need to be a pointer. You can define your
m_imglist variable as CImageList instead of a CImageList *.

I have a class derived from CTreeCtrl that I would like to change
the images of using SetImageList(). Code in OnInitDialog() of the
class that has the CTreeCtrl as a member:

CBitmap bmp;
int res;
CImageList* img;

res = bmp.LoadBitmap(IDB_IMAGE_BITMAP);
m_imglist = new CImageList;
res = m_imglist->Create(16, 14, ILC_COLOR24, 1, 0);
res = m_imglist->Add(&bmp, RGB(255, 255, 255));
img = m_TreeCtl->SetImageList(m_imglist, TVSIL_NORMAL);

All return values indicate success, but there are no images displayed.
Anything I'm missing?

Thanks,
Drew
