Specifies how the object is represented. Valid values are taken from the enumeration DVASPECT or DVASPECT2.
Pointer to a RECT structure specifying the bounding rectangle of the OLE control client area.
Pointer to the POINT structure specifying the point to be checked for a hit. The point is specified in OLE client area coordinates.
The distance that defines "close" to the point checked for a hit.
Pointer to the result of the hit query. One of the following values:
HITRESULT_OUTSIDEptlLoc is outside the OLE object and not close.
HITRESULT_TRANSPARENTptlLoc is within the bounds of the OLE object, but not close to the image. For example, a point in the middle of a transparent circle could be HITRESULT_TRANSPARENT.
HITRESULT_CLOSEptlLoc is inside or outside the OLE object but close enough to the object to be considered inside. Small, thin, or detailed objects may use this value. Even if a point is outside the bounding rectangle of an object it may still be close (this is needed for hitting small objects).
HITRESULT_HITptlLoc is within the image of the object.
