The database field referenced by the AllPropertiesMember must be of a type that is able to store a byte array of variable size per record. The exact type of the field is a function of the data provider. For SQL Server, the 'varbinary' type can be used; for MS Access, the 'OLE Object' type can be used.
The Project class's Save method returns a byte array that is compatible for use with the AllPropertiesMember field.
