以下是我的程序中用到的一部代码,关键内容都已经在其中

BEGIN_MESSAGE_MAP(CListCtrlEx, CListCtrl)
//{{AFX_MSG_MAP(CExListCtrl)
......
ON_NOTIFY_REFLECT(NM_CUSTOMDRAW, OnCustomDraw)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()


void CListCtrlEx::OnCustomDraw(NMHDR* pNMHDR, LRESULT* pResult)
{
LPNMLVCUSTOMDRAW lplvcd = (LPNMLVCUSTOMDRAW)pNMHDR;
DWORD dp=0;
switch(lplvcd->nmcd.dwDrawStage)
{
case CDDS_PREPAINT:
// Request prepaint notifications for each item.
*pResult = CDRF_NOTIFYITEMDRAW;
break;

case CDDS_ITEMPREPAINT: // Requested notification
if (!m_clrTextMap.IsEmpty()||!m_clrTextBkMap.IsEmpty())
{
dp=GetItemData((int)lplvcd->nmcd.dwItemSpec);
DWORD Text,TextBk;
COLORREF clrT,clrTB;
long lResult=GetItemColorIndex(dp,Text,TextBk);
