关于CTreeCtrl控件

[愤怒的豆沙包]

最近在学习OCX控件，想做一个仅仅显示一个TreeView控件，内容设置好了，该怎么设置去显示它呢？

int CAa_testCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
	if (COleControl::OnCreate(lpCreateStruct) == -1)
		return -1;

	m_treeDlog = new treeDlog();
	//Check if new succeeded and we got a valid pointer to a dialog object
	if(m_treeDlog != NULL)
	{
		BOOL ret = m_treeDlog->Create(IDD_FORMVIEW,this);
		if(!ret)   //Create failed.
			AfxMessageBox(_T("Error creating Dialog"));
		m_treeDlog->ShowWindow(SW_SHOW);
	}
	else
		AfxMessageBox(_T("Error Creating Dialog Object"));
	

	//m_treeDlog.ShowCaret();

	TV_INSERTSTRUCT tvinsert;
	tvinsert.hParent=NULL;
	tvinsert.hInsertAfter=TVI_LAST;
	tvinsert.item.mask=TVIF_IMAGE|TVIF_SELECTEDIMAGE|TVIF_TEXT|TVIF_STATE;
	tvinsert.item.hItem=NULL;
	tvinsert.item.state=INDEXTOSTATEIMAGEMASK( 1 );
	tvinsert.item.stateMask=TVIS_STATEIMAGEMASK;
	tvinsert.item.cchTextMax=6;
	tvinsert.item.iSelectedImage=1;
	tvinsert.item.cChildren=0;
	tvinsert.item.lParam=0;

	tvinsert.item.pszText = (unsigned short*)"dfdf";
	tvinsert.item.iImage=0;
	HTREEITEM hRoot=m_treeCtrl.InsertItem(&tvinsert);

	m_treeCtrl.SetItemState( hRoot, INDEXTOSTATEIMAGEMASK(0), TVIS_STATEIMAGEMASK , true);

	//second level
	tvinsert.hParent=hRoot;
	tvinsert.item.iImage=0;
	tvinsert.item.pszText=(unsigned short*)"江苏省";
	m_treeCtrl.InsertItem(&tvinsert);
	
	tvinsert.hParent=hRoot;
	tvinsert.item.pszText=(unsigned short*)"湖北省";
	HTREEITEM h1=m_treeCtrl.InsertItem(&tvinsert);
	
	tvinsert.hParent=hRoot;
	tvinsert.item.pszText=(unsigned short*)"广东省";
	m_treeCtrl.InsertItem(&tvinsert);
	
	tvinsert.hParent=h1;
	tvinsert.item.pszText=(unsigned short*)"武汉市";
	m_treeCtrl.InsertItem(&tvinsert);
	

	AfxMessageBox( (LPCTSTR)"InsertItem", MB_OK, 0);

	m_treeCtrl.ShowWindow(SW_SHOW);
	return 0;
}
