UniDAC with Interbase and Unicode TMemoField

Hi,

I have narrowed down an issue with Interbase and UniDAC with Unicode based Memo fields.

I'm having a problem saving to this type of field with any Unicode data - using Params. I think the problem is evident however with Unidac when creating TFields at Design Time. The Firebird 2.5 Unicode Blob Field is being created as a TMemoField and not a TWideMemoField. My thought is because UniDAC doesn't seem to support the EnableMemos feature that IBDac does. Does anyone know of a way around this?

Thanks,

Rhett

Hi, sorry - wasn't trying to duplicate issues. I'm sure these 2 are related, but this was more a design time TField Creation issue. So will this same fix for the link also fix this at Design Time?

Thanks,

You should set the UseUnicode specific option to True in the following way:

Code: Select all

UniConnection.SpecificOptions.Values['UseUnicode'] := 'True';

In this case UniDAC creates TWideMemoField fields for BLOB fields with subtype 1. Otherwise UniDAC creates TMemoField fields.
