如何根据MFC中CListCtrl的单元格值来获取一行CListCtrl

问题描述

我正在使用以下处理程序来突出显示一行但是在这里我无法根据CListCtrl的单元格值进行突出显示。请非常紧急。



以下是CListCtrl的指针。

I am using the following handler to highlight a row but here i am not able to highlight based on cell value of a CListCtrl. please its very urgent.

this following is the pointer for CListCtrl.

CListCtrl *ptrListHistory;

afx_msg void OnNMCustomdrawListHistory(NMHDR *pNMHDR, LRESULT *pResult);

void CCylanceCollectDlg::OnNMCustomdrawListHistory(NMHDR *pNMHDR, LRESULT *pResult)
{
    LPNMLVCUSTOMDRAW pLVCD = reinterpret_cast<lpnmlvcustomdraw>(pNMHDR);
    
    *pResult = CDRF_DODEFAULT;
    
    switch(pLVCD->nmcd.dwDrawStage)
    {
        case CDDS_PREPAINT:
        *pResult = CDRF_NOTIFYITEMDRAW;
        break;
        
        case CDDS_ITEMPREPAINT:
        {
            /*COLORREF crText;
            if ( (pLVCD->nmcd.dwItemSpec) == 0 )
            crText = RGB(0,0,255);*/
            /*else if ( (pLVCD->nmcd.dwItemSpec % 3) == 1 )
            crText = RGB(0,255,0);*/
            
            
            // Store the color back in the NMLVCUSTOMDRAW struct.
            /*pLVCD->clrText = crText;*/
            
            // Tell Windows to paint the control itself.
            *pResult = CDRF_NOTIFYPOSTPAINT;
        }
        break;
        
        case (CDDS_ITEMPREPAINT | CDDS_SUBITEM):
        {
            LVITEM rItem;
            int    nItem = static_cast<int>( pLVCD->nmcd.dwItemSpec );
            
            ZeroMemory ( &rItem, sizeof(LVITEM) );
            rItem.mask  = LVIF_IMAGE | LVIF_STATE;
            rItem.iItem = nItem;
            rItem.stateMask = LVIS_SELECTED;
            ptrListHistory->GetItem(&rItem);//.GetItem ( &rItem );
            
            
            *pResult = CDRF_NEWFONT;
            return;
            //if(lpLVCustomDraw->iSubItem == 1)
            //{
            ////if(lpLVCustomDraw->nmcd.lItemlParam)
            //{
            //   lpLVCustomDraw->clrText = RGB(255, 0, 0);
            //  }
            //}
            // *pResult = CDRF_NEWFONT;
            //            return;
        }
        default:
            break;
    }
}

My problem is i want to highlight a row based on the cell value of CListCtrl.

for example

I have the following rows in my listcontrol

SNo                  URl                                  LastVisitDate

1      https://accounts.google.com/ServiceLoginAuth       20/03/2014 11:22:57

2      https://accounts.google.com/ServiceLoginAuth       20/03/2014 11:22:39

3      https://accounts.google.com/ServiceLoginAuth       20/03/2014 11:22:16

4      https://accounts.google.com/ServiceLoginAuth       20/03/2014 11:22:07

So from the above rows I want highlight a row when i clicked on tree node  based on the recent LastVisitDate value in CListCtrl in the mfc application
