Disregard this inquiry - I've figured it out. I needed to call lyr.SetFeature(feat); immediately after Feature.SetField

Everything works great, except that I cannot get my changed field values saved to disk. I open the .shp for update, calls Feature.SetField and DataSource.SyncToDisk but the changed field value does not appear in the .dbf. No files are being written. How do I get my changed fields to persist back on the disk? My code: OSGeo.OGR.DataSource ds = OSGeo.OGR.Ogr.Open(shpFileName, 1); OSGeo.OGR.Layer lyr = ds.GetLayerByIndex(0); lyr.ResetReading(); OSGeo.OGR.Feature feat = lyr.GetNextFeature(); while (feat != null) { feat.SetField("Lat", -999); feat = lyr.GetNextFeature(); } ds.SyncToDisk(); -Tom
