Hi,
I wanna set new field value to an existing shape file which has been
opened with update access, but it doesn't work, my code like this:
OGRFeature* pFeature = pLayer->GetFeature(2);
int nIdx = pFeature->GetFieldIndex("Name");
pFeature->UnsetField(nIdx);
pFeature->SetField( "Name", "hanJ reiver" );
Anyone give me some advices?
Chen Xuexia,
After modifying the in memory feature, you need to write it back to the
file using OGRLayer::SetFeature().
Best regards,
