I' ve got a listbox on a dialogbox.
I want to make a drag list box.

As it described in Win32 Programmer's Reference I used
MakeDragList(hlistbox);
then
uDragListMsg=RegisterWindowMessage(DRAGLISTMSGSTRING);

So when processing uDragListMsg I see that no DL_DRAGGING notification comes. DL_BEGINDRAG, DL_CANCELDRAG, DL_DROPPED work good.

Same trouble occurs when I compile any other compiler.

/*============================================================================*/
int Process_WM_MYDRAGLISTBOXMSG(HWND hwnd, WPARAM wParam, LPARAM lParam)
{

switch ( (*(DRAGLISTINFO *)lParam).uNotification )
{
case DL_BEGINDRAG:
break;
case DL_CANCELDRAG:
break;
case DL_DRAGGING:
DrawInsert(hwnd, GetDlgItem(hwnd, wParam), DL_MOVECURSOR);
return DL_MOVECURSOR;
case DL_DROPPED:
break;
default:
return FALSE;
}
return TRUE;
}
