SUMMARY

The Microsoft Jet 2.0/Visual Basic 3.0 Compatibility Layer for Visual Basic version 3.0 provides an updated Paradox ISAM driver that allows access to Paradox 4.x tables. However, the following Paradox 4.x data types are not supported by the Paradox ISAM driver. Therefore, fields that use these data types will not be available in Visual Basic:

  • BINARY BLOB (type B)
  • FORMATTED MEMO (type F)
  • GRAPHIC BLOB (type G)

MORE INFORMATION

If you attempt to open a Paradox 4.x table that contains a field that has an unsupported data type, that field will be ignored by Visual Basic. The field will not appear at all in the fields collection of any Visual Basic data access object (tabledef, table, dynaset, or snapshot).

NOTE: Visual Basic does recognize and work with Paradox OLE BLOB fields, just not BINARY BLOB or GRAPHIC BLOB fields.
