CListCtrl, 重载DrawItem 函数
定义你自己的类，继承CListCtrl 类，然后重载DrawItem 函数，并保证在属性中有LVS_OWNERDRAWFIXED 风格.
exp:
CListCtrlExt m_ListCtrl;
m_ListCtrl.ModifyStyle(0,LVS_OWNERDRAWFIXED,0);
void CListCtrlExt::DrawItem(LPDRAWITEMSTRUCT lpDIS)
{
int nItem=lpDIS->itemID;
if(nItem == -1)
return ;
CRect rcCol = lpDIS->rcItem;
CString sText;
CDC* pDC=CDC::FromHandle(lpDIS->hDC);
int nOldDCMode=pDC->SaveDC();
LVITEM item;
item.iItem = nItem;
item.iSubItem = 0;
item.mask = LVIF_IMAGE|LVIF_STATE;
item.stateMask = 0XFFFF;
GetItem(&item);
BOOL bSelected = item.state&LVIS_SELECTED;
COLORREF color=::GetSysColor(COLOR_WINDOW);
if(bSelected )
{
pDC->SetBkColor(::GetSysColor(COLOR_HIGHLIGHT));
pDC->SetTextColor(::GetSysColor(COLOR_HIGHLIGHTTEXT));
color=::GetSysColor(COLOR_HIGHLIGHT);
}
else
{
pDC->SetBkColor(color);
pDC->SetTextColor(::GetSysColor(COLOR_WINDOWTEXT));
}
LV_COLUMN lvc;
lvc.mask=LVCF_FMT|LVCF_WIDTH;
rcCol.right = rcCol.left;
for(int nCol=0; GetColumn(nCol,&lvc); nCol++)
{
rcCol.left = rcCol.right;
rcCol.right = rcCol.left + GetColumnWidth(nCol);
HPEN hOldPen = (HPEN)::SelectObject(lpDIS->hDC, ::CreatePen(PS_SOLID, 1, RGB(0xc0,0xc0,0xc0)));
HBRUSH hOldBrush = (HBRUSH)::SelectObject(lpDIS->hDC, ::CreateSolidBrush(color));
::Rectangle(lpDIS->hDC, rcCol.left-1, rcCol.top-1, rcCol.right, rcCol.bottom);
::DeleteObject(SelectObject(lpDIS->hDC, hOldBrush));
::DeleteObject(SelectObject(lpDIS->hDC, hOldPen));
sText=MakeShortString(pDC,GetItemText(nItem,nCol),rcCol.Width());
pDC->DrawText(sText, -1, CRect::CRect(rcCol.left+3,rcCol.top,rcCol.right,rcCol.bottom-2), DT_LEFT);
}

CListView实现自画功能
在实现自画功能的时候, 注意要画的时候只能对一个CRect 里面来描画, 也就是说对一个item 所占的格子进行描画, 不能同时画这个区域,DrawItem 函数当画面有什么变化时都会自动调用.
// 機能：DrawItem 関数のオーバーライドので、リストビューの自画ことができる。

最后在保存到html 里面, 注意<PRE></PRE> 语法是用于保存txt 里面的内容原封不动的放到html 里面, 还要注意用:<table width= "...."> 来控制画面的大小
通过处理NM_CUSTOMDRAW ，可以实现你的功能！但是NM_CUSTOMDRAW 在Class Wizard 中有可能看不到，不用管他，直接按照小面的方法添加处理过程即可！
1. 在消息映射表中
BEGIN_MESSAGE_MAP(CIHISSERVERView, CListView)
//{{AFX_MSG_MAP(CIHISSERVERView)
...
ON_NOTIFY_REFLECT(NM_CUSTOMDRAW, OnCustomDraw)
...
//}}AFX_MSG_MAP
// Standard printing commands
END_MESSAGE_MAP()
2. 在头文件中
afx_msg void OnCustomDraw(NMHDR*, LRESULT*);
3. 在cpp 文件中
void CIHISSERVERView::OnCustomDraw(NMHDR* pNMHDR, LRESULT* pResult)
