pt
The position to hit test, in client coordinates.
flags
The variable that receives information about the results of a hit test. This member can be one or more of the following values:
You can use LVHT_ABOVE, LVHT_BELOW, LVHT_TOLEFT, and LVHT_TORIGHT to determine whether to scroll the contents of a list-view control. Two of these values may be combined. For example, if the position is above and to the left of the client area, you could use both LVHT_ABOVE and LVHT_TOLEFT.
You can test for LVHT_ONITEM to determine whether a specified position is over a list-view item. This value is a bitwise-OR operation on LVHT_ONITEMICON, LVHT_ONITEMLABEL, and LVHT_ONITEMSTATEICON.
LVHT_ABOVE
The position is above the control's client area.
LVHT_BELOW
The position is below the control's client area.
LVHT_NOWHERE
The position is inside the list-view control's client window, but it is not over a list item.
LVHT_ONITEMICON
The position is over a list-view item's icon.
LVHT_ONITEMLABEL
The position is over a list-view item's text.
LVHT_ONITEMSTATEICON
The position is over the state image of a list-view item.
LVHT_TOLEFT
The position is to the left of the list-view control's client area.
LVHT_TORIGHT
The position is to the right of the list-view control's client area.
