It is good to see that you got your code working.
I noticed that you were providing a value for the ID property. In SHP, I believe that the identifier is always auto-generated. Perhaps the SHP Provider is not checking, but some providers are more strict and may throw an exception if you supply a value for an auto-generated property.
To find out whether a property is auto-generated, you can use the FdoIDescribeSchema command, and search the resulting object tree for the needed property. The FdoDataPropertyDefinition:: GetIsAutoGenerated() method will say whether the property is auto-generated (in which case, it is best to not provide a value during an Insert).

Thanks a lot Jason. Now work fine.
