flags
Receives information about the results of a hit test. It can be one or more of the following values.
| Value | Description |
| HHT_NOWHERE | The point is inside the header control’s bounding rectangle but is not over a header item. |
| HHT_ONDIVIDER | The point is on the divider between two header items. |
| HHT_ONDIVOPEN | The point is on the divider of an item that has a width of zero. Dragging the divider reveals the item instead of resizing the item to the left of the divider. |
| HHT_ONHEADER | The point is inside the header control’s bounding rectangle. |
| HHT_TOLEFT | The point is to the left of the header control’s bounding rectangle. |
| HHT_TORIGHT | The point is to the right of the header control’s bounding rectangle. |
Two of these values can be combined, such as when the position is above and to the left of the client area.
iItem
Receives the index of item at point, if any.
