Missign Columntypes

Mar 3, 2011 at 7:16 PM


I'm using the previous release(before 11 februari 2011) and I'm missing 4 columntypes which cannot be retrieved if I'm correct?

Unsigned Short
Unsigned Long



Is this taken care off in the present version? Otherwise will this be added in the near future? I really need columtype 14 and 16 to

be implemented for my project.

There is full support for those types in the current (1.6) version.

I use JET_coltyp.* in a switch statement to figure how to retreive a column. However playing with the new version this weekend I couldn't use columntypes like this:




How can I match these columns?

Those types were added in Vista so you need to use


using Microsoft.Isam.Esent.Interop.Vista;

case VistaColtyp.LongLong:
case VistaColtyp.UnsignedShort:
