ANNHITTESTINFO

typedef struct tagANNHITTESTINFO 
{ 
   L_UINT uStructSize;  //size of this structure 
   L_INT nHandleIndex; 
   L_INT nHandleID; 
   L_INT nReserved; 
}ANNHITTESTINFO, *pANNHITTESTINFO;

The ANNHITTESTINFO structure provides hit test information for the LImageListControl::HitTest function.

Member	Description
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.
nHandleID	The unique ID associated with the user handle.
nReserved	Reserved for future use. Set this field to zero.
