Description
TBytesField represents a bytes field in a dataset.
Data.DB.TVarBytesField inherits from Data.DB.TBytesField. All content below this line refers to Data.DB.TBytesField.
TBytesField represents a bytes field in a dataset.
TBytesField encapsulates the fundamental behavior common to bytes fields. A bytes field value is a set of unformatted bytes of fixed size.
If you use the Fields editor at design time to create a persistent field component for the bytes field, you can access it by name at runtime. When using dynamic field components, you can access the TBytesField instance using the dataset's Fields property or FieldByName method.
