BinaryFile

Object List Hierarchy Next Object

Definition:

The BinaryFile object is used to read from and write to files in a mode that does not interpret the contents of the file as ASCII text (compare this with TextFile, which does interpret the contents as ASCII text). Binary files in general are not usually directly human-readable.

Specialized Features:

The following tables list and briefly describe the properties and methods added by BinaryFile. There are no added events.

---

Properties Use to...

---

Handle Access the file handle of an open binary file.

IsOpen Indicate whether or not the binary file is open (Read Only).

Position Determine the current position in the binary file.

SwapBytes Determine whether to swap the byte-order of numbers read with ReadInteger, ReadLong, ReadSingle, ReadDouble, etc.
