MFC中ListCtrl，改变具体单元格的文本和背景颜色

先要创建NM_CUSTOMDRAW的消息

// A code block
var foo = 'bar';

// An highlighted block
void CStudentDlg::OnNMCustomdrawList(NMHDR *pNMHDR, LRESULT *pResult)
{
	NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>(pNMHDR);
	// TODO: Add your control notification handler code here
	*pResult = CDRF_DODEFAULT;


	if (CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage)
	{
		*pResult = CDRF_NOTIFYITEMDRAW;
	}
	else if (CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage)
	{
		// This is the notification message for an item. We'll request
		// notifications before each subitem's prepaint stage.

		*pResult = CDRF_NOTIFYSUBITEMDRAW;
	}//这上面的都是默认的不用理
	else if ((CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage)
	{
		COLORREF clrNewTextColor, clrNewBkColor;//当前单元格的文本颜色以及背景颜色
		int nItem = static_cast<int>(pLVCD->nmcd.dwItemSpec);//当前行
		CString strTemp = mList.GetItemText(nItem, pLVCD->iSubItem);//当前行的某一列的内容
		switch (pLVCD->iSubItem)//pLVCD->iSubItem表示当前列，等到所有列都遍历完才会进入下一行
		{
		case 3://表明处理到此行的第3列时
		{
				  int age = atoi((CT2A(strTemp.GetBuffer())));//字符串转int
				  if (age > 22 || age < 18)//当年龄超过范围，设置字体颜色异常
				  {
					  clrNewTextColor = RGB(255, 0, 0);
					  clrNewBkColor = RGB(255, 255, 255);
					  pLVCD->clrText = clrNewTextColor;
					  pLVCD->clrTextBk = clrNewBkColor;
				  }  
				  else //正常年龄范围为黑色文本
				  {
					  pLVCD->clrText = RGB(0, 0, 0);
					  pLVCD->clrTextBk = RGB(255, 255, 255);
				  }
				  *pResult = CDRF_DODEFAULT;
				  break;
		}
		case 4://表明处理到此行的第4列时
		{
				  int height = atoi((CT2A(strTemp.GetBuffer())));//字符串转int
				  if (height > 190 || height < 150)//当身高超过范围，设置字体颜色异常
				  {
					  clrNewTextColor = RGB(0, 0, 255);
					  clrNewBkColor = RGB(255, 255, 255);
					  pLVCD->clrText = clrNewTextColor;
					  pLVCD->clrTextBk = clrNewBkColor;
				  }
				  else //正常年龄范围为黑色文本
				  {
					  pLVCD->clrText = RGB(0, 0, 0);
					  pLVCD->clrTextBk = RGB(255, 255, 255);
				  }
				  *pResult = CDRF_DODEFAULT;
				  break;
		}
		default://默认为黑色文本
			pLVCD->clrText = RGB(0, 0, 0);
			pLVCD->clrTextBk = RGB(255, 255, 255);
			*pResult = CDRF_DODEFAULT;
			break;
		}
	}
}

下面的第3列和第四列就是对应上面case 3和case 4的处理
