NM_CUSTOMDRAW CDDS_ITEMPREPAINT时 isubitem 值一直为0

[woshi_hujunjun]

问题如题：
LPNMCUSTOMDRAW pNMCD = reinterpret_cast<LPNMCUSTOMDRAW>(pNMHDR);
NMLVCUSTOMDRAW * lplvdr = (NMLVCUSTOMDRAW*)pNMHDR;
switch (lplvdr->nmcd.dwDrawStage)
{
case CDDS_PREPAINT:
*pResult = CDRF_NOTIFYITEMDRAW;
return;
case CDDS_ITEMPREPAINT:
{
//lplvdr->iSubItem
int a = _ttoi(GetItemText(pNMCD->dwItemSpec, 1));
if (a == 1)
{
lplvdr->clrText = RGB(255, 0, 0);
//lplvdr->clrTextBk = ;
}
}
*pResult = CDRF_DODEFAULT;

void CReportCtrl::OnCustomDraw(NMHDR* pNMHDR, LRESULT* pResult) 
{
	LPNMLVCUSTOMDRAW lplvcd = (LPNMLVCUSTOMDRAW)pNMHDR;

	if (lplvcd->nmcd.dwDrawStage == CDDS_PREPAINT)

    else if (lplvcd->nmcd.dwDrawStage == CDDS_ITEMPREPAINT)
	{
	    *pResult = CDRF_NOTIFYSUBITEMDRAW;
	}
    else if (lplvcd->nmcd.dwDrawStage == (CDDS_ITEMPREPAINT | CDDS_SUBITEM))
    {
		CItemData* p = (CItemData*)(CListCtrl::GetItemData(lplvcd->nmcd.dwItemSpec));
		ASSERT(p != NULL);

注意 CDRF_NOTIFYSUBITEMDRAW;
