m_TreeView.InsertItem(L"Skills");
HTREEITEM main = m_TreeView.InsertItem(L"Technical");
m_TreeView.InsertItem(L"C++", main);
m_TreeView.InsertItem(L"Java", main);
m_TreeView.InsertItem(L".Net", main);

First of all you need to create CImageList object instance.

m_TreeIcons.Create(16, 16, ILC_COLOR32|ILC_MASK, 0, 1);

You can use either bitmap or icon as image source.

m_FileIcons.Add(AfxGetApp()->LoadIcon(IDI_FOLDER));
m_FileIcons.Add(AfxGetApp()->LoadIcon(IDI_FILE));

And the last step is to bind your image list with your tree:

m_Tree.SetImageList(&m_TreeIcons, LVSIL_SMALL);
