<br>内容：iImage并不是你的BITMAP的资源ID，而是imagelist的次序。<BR>1.在你的CTreeDlg.h中定义一个成员变量：CImageList imageTree;<BR><BR>2.在CDialog::OnInitDialog();后加上下面的代码：<BR>imageTree.Create(16, 16, ILC_MASK, 1, 0);&nbsp;&nbsp;&nbsp;&nbsp;// 大小为16x16<BR>imageTree.SetBkColor(RGB(255,255,255));&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// 背景色为白色<BR>CBitmap bmpItem;<BR>bmpItem.LoadBitmap(IDB_BITMAP1);<BR>imageTree.Add(&amp;bmpItem, RGB(255, 255, 255));<BR>m_TreeCtrl.SetImageList(&amp;imageTree, TVSIL_NORMAL);<BR><BR>3.再把tvItem.iImage=IDB_BITMAP1换成：<BR>tvItem.iImage = 0;<BR><BR><BR>
