Re[fdo-users] turn geometries

[Gavin Cramer]

So... is the problem that ReadNext() only returns 'true' once, or that all geometries have the same value?

For instance, there are 44 counties within one shapefile - it only returns
one.  There are 100+ points in another shapefile, it only returns one.

NOTE: pcoords holds the geometry from GetGeometry - it is type byte[].  I
acutally pass this byte[] into another function to convert it into geometry
with CreateGeometryFromFgf.  That is why the code is not clear with the loop
and the definition of pcoords.

Thanks....
