ADO GetChunk Method
 Complete Field Object Reference
The GetChunk method returns a variant that contains all or a part of the
contents of a large text or binary data Field object.
This method can divide long values into small portions, so if the system
memory is limited and can't deal with long values, this method can be used.
When the GetChunk method is called, it starts to retrieve data from where the previous GetChunk call
ended, as long as you stay on the same field in the current record.
You can use the GetChunk method for a field if the Attributes property of a
Field object is set to adFldLong.
Note: There has to be a current record when you use the GetChunk method on a Field
object.
Note: This method does not work on Field objects of a Record object.
