<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal">I’m using OGR via the swig/C# wrapper. 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?
