[fdo-users] Insert new feature object on SHP File

[Jason Birch]

I'm not an FDO coder, but there are a couple things I'd look at.

First, FDODimensionality isn't an integer value representing the number of
dimensions, it's a bit-field enumeration. In this case, 2 evaluates to
FdoDimensionality_M (although, since the value of FdoDimensionality_XY is 0,
this is included by default in the evaluation of FdoDimensionality_M -
neat).

http://fdo.osgeo.org/files/fdo/docs/FDO_API/d3/d95/group__enums_g3778ef9845e2ba00e8669c32ec42e113.htm#g3778ef9845e2ba00e8669c32ec42e113

Second, the docs for CreateLineString indicate that it's looking for the
number of ordinates, not co-ordinates.  I'm not sure if this is just a
terminology issue, but perhaps it is looking for 6 in your case.
