Description

Creates a blob stream for a Binary large object (BLOB) field in the dataset.

Call CreateBlobStream to obtain a stream for reading and writing the value of the field specified by the Field parameter.

Field is a string containing the name of the BLOB (or comparable type) field in the dataset.

Mode indicates whether the stream will be used for reading the field's value (bmRead), writing the field's value (bmWrite), or both (bmReadWrite).
