Syntax
HDN_ENDDRAG pNMHeader = (LPNMHEADER) lParam;
Parameters
pNMHeader
Pointer to an NMHEADER structure that contains data about the header item dragged
Return Values
To enable the control to automatically place and reorder the item, return FALSE. Return TRUE to prevent the item from being placed.
Remarks
If the owner is performing external (manual) drag-and-drop management, it must return FALSE. The owner then must reorder header items manually by sending HDM_SETITEM or HDM_SETORDERARRAY.
