网上关于在CListCtrl控件里面点击直接修改值的东西比较少，其实是个很简单的东西，知识不太容易想到！在这里将代码写下！

void CAdminDialog::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
// TODO: Add your control notification handler code here
Invalidate();
HWND hWnd1 = ::GetDlgItem(m_hWnd,IDC_LIST1);
LPNMITEMACTIVATE temp = (LPNMITEMACTIVATE) pNMHDR;
RECT rect;
//get the row number
nItem = temp->iItem;
//get the column number
nSubItem = temp->iSubItem;
if(nSubItem == 0 || nSubItem == -1 || nItem == -1)
return ;
//Retrieve the text of the selected subItem from the list
str1 = GetItemText(hWnd1,nItem ,nSubItem);
RECT rect1,rect2;
// this macro is used to retrieve the Rectanle of the selected SubItem
ListView_GetSubItemRect(hWnd1,temp->iItem,temp->iSubItem,LVIR_BOUNDS,&rect);
//Get the Rectange of the listControl
::GetWindowRect(temp->hdr.hwndFrom,&rect1);
//Get the Rectange of the Dialog
::GetWindowRect(m_hWnd,&rect2);

int x=rect1.left-rect2.left;
int y=rect1.top-rect2.top;

if(nItem != -1)
::SetWindowPos(::GetDlgItem(m_hWnd,IDC_EDIT1),HWND_TOP,rect.left + x,rect.top + y,rect.right-rect.left,rect.bottom-rect.top,NULL);
//GetDlgItem(IDC_EDIT1)->SetWindowText(str1);//°ÑEditµÄ¿Ø¼þÖµÉèΪCListCtrlÀïÃæµÄÖµ
m_List.SetItemText(nItem,nSubItem,"");//½«CListCtrlÀïÃæµÃÖµÉèÖóɲ»¿É¼ûµÄ

::ShowWindow(::GetDlgItem(m_hWnd,IDC_EDIT1),SW_SHOW);
::SetFocus(::GetDlgItem(m_hWnd,IDC_EDIT1));
//Draw a Rectangle around the SubItem
::Rectangle(::GetDC(temp->hdr.hwndFrom),rect.left + x,rect.top,rect.right,rect.bottom);
GetDlgItem(IDC_EDIT1)->GetWindowText(str1);//µÃµ½Ð޸ĺóµÄÖµ£¬ÒÔ·½±ãÈ·¶¨Ð޸ĺ󽫴ËÖµÖ±½Óдµ½CListCtrlÉÏ

//Set the listItem text in the EditBox
//::SetWindowText(::GetDlgItem(m_hWnd,IDC_EDIT1),str1);

*pResult = 0;
}

CString CAdminDialog::GetItemText(HWND hWnd, int nItem, int nSubItem) const
{

memset(&lvi, 0, sizeof(LVITEM));
lvi.iSubItem = nSubItem;

nLen *= 2;
lvi.cchTextMax = nLen;
lvi.pszText = str.GetBufferSetLength(nLen);
nRes = (int)::SendMessage(hWnd, LVM_GETITEMTEXT, (WPARAM)nItem,
(LPARAM)&lvi);
} while (nRes == nLen-1);
str.ReleaseBuffer();
return str;
}
