简介一边听听音乐，一边写写文章。
typedef struct _info{
CListCtrl * m_list;
int col;
bool asc;
}INFO;
bool asc = true;
一、基于视图工程 CListView
int CALLBACK CompareFunc(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
{
CString text1,text2;
INFO* info = (INFO*)lParamSort;
LVFINDINFO fi;
fi.flags = LVFI_PARAM;
fi.lParam = lParam1;
LVFINDINFO fi1;
fi1.flags = LVFI_PARAM;
fi1.lParam = lParam2;
//从LVITEM结构中的lParam成员来查找对应项的索引号
int index1 = info->m_list->FindItem(&fi);
int index2 = info->m_list->FindItem(&fi1);
text1 = info->m_list->GetItemText(index1, info->col);
text2 = info->m_list->GetItemText(index2, info->col);
int i = 0;
if (info->asc)
i = wcscmp(text1.GetBuffer(), text2.GetBuffer());
else
i = wcscmp(text2.GetBuffer(), text1.GetBuffer());
return i;
}
void CDemoView::OnLvnColumnclick(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);
// TODO: Add your control notification handler code here
static int iSorted = -1; //排序列号
if (pNMLV->iSubItem == iSorted)
asc = !asc;
CListCtrl &ctrl = GetListCtrl();
INFO info;
info.col = iSorted = pNMLV->iSubItem;
info.m_list = &ctrl;
info.asc = asc;
ctrl.SortItems((PFNLVCOMPARE)CompareFunc, (LPARAM)&info);
*pResult = 0;
}
typedef struct _info{
