m_pImageList->Add(&m_bitmap, (COLORREF)0x000000);
m_pImageList->SetOverlayImage(0,1);
m_ctrltree.SetImageList(m_pImageList,0);
m_bitmap.DeleteObject();
m_bitmap.LoadBitmap(IDB_BITMAP_USER);
m_pImageList->Add(&m_bitmap, (COLORREF)0x000000);
m_pImageList->SetOverlayImage(2,1);
m_ctrltree.SetImageList(m_pImageList,0);

Answer 1

HICON hicon[4];
    m_imageList.Create(16 ,16 , TRUE | ILC_COLOR16, 8, 8);
    hicon[0]=AfxGetApp()->LoadIcon(IDI_ITEMICON1);
    hicon[1]=AfxGetApp()->LoadIcon(IDI_ITEMICON2);
    hicon[2]=AfxGetApp()->LoadIcon(IDI_ITEMICON3);
    hicon[3]=AfxGetApp()->LoadIcon(IDI_ITEMICON4);
    for(int n = 0 ;n < 4;n++)
        m_imageList.Add(hicon[n]);
    m_ShowConfig.SetImageList(&m_imageList, TVSIL_NORMAL);

Answer 2

HICON   hicon[4]; 
        m_imageList.Create(16   ,16   ,   TRUE   ¦   ILC_COLOR16,   8,   8); 
        hicon[0]=AfxGetApp()-> LoadIcon(IDI_ITEMICON1); 
        hicon[1]=AfxGetApp()-> LoadIcon(IDI_ITEMICON2); 
        hicon[2]=AfxGetApp()-> LoadIcon(IDI_ITEMICON3); 
        hicon[3]=AfxGetApp()-> LoadIcon(IDI_ITEMICON4); 
        for(int   n   =   0   ;n   <   4;n++) 
                m_imageList.Add(hicon[n]);     CTreeCtrl* pTree=(CTreeCtrl*)pWnd;
pTree->SetImageList(pImageList,TVSIL_NORMAL);
        HTREEITEM hItem=pTree->InsertItem("工程信息",1,2);

Answer 3

                HICON       hicon[4];   
                m_imageList.Create(16       ,16       ,       TRUE       ¦       ILC_COLOR16,       8,       8);   
                hicon[0]=AfxGetApp()->   LoadIcon(IDI_ITEMICON1);   
                hicon[1]=AfxGetApp()->   LoadIcon(IDI_ITEMICON2);   
                hicon[2]=AfxGetApp()->   LoadIcon(IDI_ITEMICON3);   
                hicon[3]=AfxGetApp()->   LoadIcon(IDI_ITEMICON4);   
                for(int n = 0;n<4;n++)   
                  m_imageList.Add(hicon[n]); 
                CTreeCtrl*   pTree = this ->GetTreeCtrl();
                pTree-> SetImageList(pImageList,TVSIL_NORMAL); 
                 HTREEITEM   hItem=pTree-> InsertItem("工程信息",1,2);   //其中第二个参数为其图片在CImageList中的索引，其第三个参数为选中时其图片的索引。
