typedef struct _HD_HITTESTINFO {  
    POINT pt;  
    UINT flags; 
    int iItem; 
} HDHITTESTINFO, FAR *LPHDHITTESTINFO;

Contains information about a hit test. This structure is used with the HDM_HITTEST message. This structure supersedes the HD_HITTESTINFO structure.

pt
POINT structure that contains the point to be hit test, in client coordinates.
flags
Variable that receives information about the results of a hit test. This member can be one or more of the following values:
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
If the hit test is successful, contains the index of the item at the hit test point.
