一、定义一个CImageList m_ImageList;
二、初始化加载图片列表：
m_ImageList.Create(18, 18, ILC_COLORDDB | ILC_MASK, 0, 1);
CBitmap camer;
CBitmap camerg;
camer.LoadBitmap(IDB_Video);
camerg.LoadBitmap(IDB_VideoGroup);
m_ImageList.Add(&camerg,RGB(192, 192, 192));
m_ImageList.Add(&camer, RGB(192, 192, 192));
m_TreeList.SetImageList(&m_ImageList,TVSIL_NORMAL);
DWORD dwStyles = GetWindowLong(m_TreeList.m_hWnd,GWL_STYLE);
dwStyles |= TVS_HASBUTTONS|TVS_HASLINES|TVS_LINESATROOT|TVS_EDITLABELS;
SetWindowLong(m_TreeList.m_hWnd,GWL_STYLE,dwStyles);
HTREEITEM hItem,hSubItem;
hItem = m_TreeList.InsertItem("Parent1",TVI_ROOT,TVI_LAST);
//在根结点上添加Parent1
hSubItem = NULL;
hSubItem = m_TreeList.InsertItem("Child1_1",1,1,hItem,hSubItem);
//在Parent1上添加一个子结点
hSubItem = m_TreeList.InsertItem("Child1_2",1,1,hItem,hSubItem);
//在Parent1上添加一个子结点，排在Child1_1后面
hSubItem = m_TreeList.InsertItem("Child1_3",1,1,hItem,hSubItem);
m_TreeList.Expand(hItem, TVE_EXPAND);
hItem = m_TreeList.InsertItem("Parent2",TVI_ROOT,hItem);
hItem = m_TreeList.InsertItem("Parent3",TVI_ROOT,hItem);
