This article was previously published under Q300189

SYMPTOMS

Microsoft Jet versions 3.51 and 4.0 provide a Paradox ISAM driver that allows access to Paradox 4.x tables. However, the Paradox ISAM driver does not support the BINARY BLOB (type B) Paradox 4.x data type. Thus, fields that use this data type will not be available in Visual Basic.

STATUS

This behavior is by design.

MORE INFORMATION

If you try to open a Data Access Objects (DAO) recordset against Paradox 4.x table that contains a field that has an unsupported data type, that field will be ignored. The field will not appear in the fields collection of any DAO object (TableDef, Table, dynaset, or snapshot).

NOTE: Although DAO does not recognize or work with Paradox BINARY BLOB fields, DAO does recognize and work with Paradox OLE BLOB fields.
