SetEOS Method
Sets the position that is the end of the stream.
Syntax
Stream.SetEOS
Remarks
SetEOS updates the value of the EOS property, by making the current Position the end of the stream. Any bytes or characters following the current position are truncated.
Because Write, WriteText, and CopyTo do not truncate any extra values in existing Stream objects, you can truncate these bytes or characters by setting the new end-of-stream position with SetEOS.
Caution
If you set EOS to a position before the actual end of the stream, you will lose all data after the new EOS position.
