Remarks

If the row's type is not visTagPolylineTo, an exception is raised.

If the GetPolylineData method succeeds, xyArray returns a one-dimensional array of n doubles (VT_R8) indexed from 0 to n - 1. The argument xyArray is an out argument that is allocated by the GetPolylineData method, which passes ownership back to the caller. The caller should eventually perform SafeArrayDestroy on the returned array. (Microsoft Visual Basic and Visual Basic for Applications manage this for you.)

The flags argument is a bit mask that specifies options for returning points. Its value should be visGeomWHPct, visGeomXYLocal, or a combination of either of those values with visGeomExcludeLastPoint. If neither visGeomWHPct nor visGeomXYLocal is passed as part of the flags argument, an error will be generated.
