[Member 10402390]

i try sort virtual list-view with click on column title but when i click nothing happens this dialog procedure:

BOOL CALLBACK DlgProc(HWND hwnd,UINT msg, WPARAM wParam,LPARAM lParam)
{
static HWND hWndList = 0;

switch(msg)
{
case WM_INITDIALOG:
{
hWndList= CreateWindowEx(0, WC_LISTVIEW, NULL,
WS_CHILD|WS_BORDER|WS_VISIBLE|LVS_OWNERDATA|LVS_REPORT,
20, 20, 620, 300, hwnd, NULL, hInstance,NULL);

  //заголовок
  LV\_COLUMN lvc;
  ZeroMemory(&lvc,sizeof(lvc));

  lvc.mask=LVCF\_FMT|LVCF\_SUBITEM|LVCF\_TEXT|LVCF\_WIDTH;
  lvc.fmt=LVCFMT\_LEFT;//выравнивание
  
  lvc.cx=150;
  lvc.pszText=(LPSTR)"имя файла";
  ListView\_InsertColumn(hWndList,0,&lvc);

  ListView\_SetItemCount(hWndList,directory.size());
  return TRUE;
}

case WM_COMMAND:
switch(LOWORD(wParam))
{
case IDOK:
case IDCANCEL:
EndDialog(hwnd,0);
return true;
}

case WM_NOTIFY:
{
switch (((LPNMHDR)lParam)->code)
{
case LVN_GETDISPINFO:
{
NMLVDISPINFO* plvdi = (NMLVDISPINFO*)lParam;

      switch (plvdi->item.iSubItem)
      {
      case 0:
        {
          plvdi->item.pszText = (LPSTR)directory\[plvdi->item.iItem\].\_name.c\_str();//"имя файла"
          break;
        }
      default:
        break;
      }
    }

    case LVN\_COLUMNCLICK:
    {
      LPNMLISTVIEW pnmv = (LPNMLISTVIEW) lParam;
      //NM\_LISTVIEW \*pnmv= (NM\_LISTVIEW\*)lParam;
      switch (pnmv->iSubItem)
      {
      case 0:
        {
          //"имя файла"
          sort(directory.begin(), directory.end(), boost::bind(less(), boost::bind(&data::\_name, \_1), boost::bind(&data::\_name, \_2)));//возростание
          break;
        }
      default:
        {break;}
      }
      ListView\_RedrawItems(hwnd, 0, directory.size() - 1);
      UpdateWindow(hwnd);
      break;
    }
  }
}

default:
return FALSE;
}
}

i don't understand why??

Did you debug it? Do you reach the lines of code you expected? If not, how far do you get?

constantly are sent LVN_COLUMNCLICK, and the list is constantly being updated

It seems that you're missing 'break' for

case LVN_GETDISPINFO:

switch block.
