csharp querybyattributes

[David Lowther]

Tamas,

So here's the weird thing: queryByAttributes gets a resultCache with the
correct number of results and correct extent for all these shapefiles
(county, Garfield, precinct). It highlights for county and precinct, but NOT
Garfield. If I queryByRect all shapefiles highlight. Of course, by highlight
I mean drawQuery shows yellow.

This all leads me to believe there is something about the shapefile causing
the issue. If you still need me to post a sample app or the shapefiles let
me know.

Do you see anything obvious I am missing?

Here's OGRINFO -so for the 3 files:

Hi,

I haven't found this kind of behaviour. Are you sure your resultcache
is not empty?
Could you post a sample to reproduce this problem?

Best Regards,

Tamas
