如何改变treeview画出来的treectrl的位置?

//CTreeView::OnInitialUpdate();
//加载图标资源
m_hIcon[0]=AfxGetApp()->LoadIcon(IDI_ICON_SENDING);
m_hIcon[1]=AfxGetApp()->LoadIcon(IDI_ICON_SENT);
m_hIcon[2]=AfxGetApp()->LoadIcon(IDI_ICON_RECYCLE);
m_hIcon[3]=AfxGetApp()->LoadIcon(IDI_ICON_COUNT);
m_hIcon[4]=AfxGetApp()->LoadIcon(IDI_ICON_CONFIG);
m_hIcon[5]=AfxGetApp()->LoadIcon(IDI_ICON_STATE);//托盘图标
for(int i=0;i<6;++i)
        m_lstImage.Add(m_hIcon[i]);
// TODO: Add your specialized code here and/or call the base class
CTreeCtrl &pTree=this->GetTreeCtrl();
pTree.SetItemHeight(19);
    pTree.SetIndent(5);
pTree.SetTextColor(RGB(0,87,174));
pTree.SetImageList(&m_lstImage,TVSIL_NORMAL);
pTree.InsertItem("正在发送...",0,0,TVI_ROOT);
pTree.InsertItem("已经发送",1,1,TVI_ROOT);
pTree.InsertItem("已删除",2,2,TVI_ROOT);
pTree.InsertItem("统计信息",3,3,TVI_ROOT);
pTree.InsertItem("简历配置",4,4,TVI_ROOT);
//SetWindowPos(&pTree,120,120,100,100,SWP_NOSIZE);
//MoveWindow(10,10,100,100,true);}
主要代码是上边的.我在左右分割的窗口左边用treeview来导航.不过它离左边窗口边框太近了.我想改变一下.比如说居中.离上边与左边有点距离..
试了一下.mov setwindow都不行.
