Members

uStructSize

Size of this structure. Use sizeof(HITTESTINFO).

nHandleIndex

This is the zero-based index of the handle. This field is valid only if puResult of is updated with either ANNHIT_HANDLE or ANNHIT_USER_HANDLE. The default handles and the user handles are maintained internally as separate arrays of handles. This means that there is both a default handle "0" and a user handle "0". This index can be used with other annotation handle functions.
