Description

TVarBytesField represents a variable-length untyped binary field in a dataset.

A variable bytes field value is a set of bytes of variable size, with the actual length of the value stored in the first two bytes.

If you use the Fields editor at design time to create a persistent field component for the variable bytes field, you can access it by name at runtime. When using dynamic field components, you can access the TVarBytesField instance using the dataset's Fields property or FieldByName method.
