C# has nullable types, and my guess would be that the ArgumentNullexception happens you assign/pass a nullable value with NULL to a non-nullable equivalent. So it could be that it corresponds to some EVariantisnull error, but that is a bit of a stretch. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
