Description¶
TByteField is instantiated when a dataset must manage a field with 8-bit unsigned data: the data type ftByte. It overrides some methods of TField to handle Byte data, and sets some of the properties to values for Byte data. It also introduces some methods and properties specific to integer data such as MinValue and MaxValue.
It should never be necessary to create an instance of TByteField manually, a field of this class will be instantiated automatically for each integer field when a dataset is opened.
Methods¶
