Warning

This item was deprecated in version 2019r2. Please use Readable.EndOfFile as a replacement.

Description

Returns True when the read reaches the end of the stream.

Sample code

This code reads the rows and columns of data from a tab-delimited text file into a ListBox:

Dim f As FolderItem
Dim textInput As TextInputStream
Dim rowFromFile, oneCell As String

f = GetOpenFolderItem("text/plain") ' defined as a FileType
If f <> Nil Then
  textInput = TextInputStream.Open(f)
  textInput.Encoding = Encodings.UTF8
Do
  rowFromFile = textInput.ReadLine
  If ListBox1.ColumnCount < CountFields(rowFromFile, Chr(9)) Then
    ListBox1.ColumnCount = CountFields(rowFromFile, Chr(9))
  End If

  ListBox1.AddRow(NthField(rowFromFile, Chr(9), 1))
  For i As Integer =1 To CountFields(rowFromFile, Chr(9))
    oneCell = NthField(rowFromFile, Chr(9), i)
    ListBox1.Cell(ListBox1.ListCount - 1, i - 1) = oneCell
  Next
  Loop Until textInput.EOF
  textInput.Close
End If

This example reads each pair of bytes from a file and writes them in reverse order to a new file. The user chooses the source file using the Open-file dialog box and saves the new file using the Save as dialog box. The EOF property is used to terminate the Do...Loop.

Dim readFile As FolderItem = GetOpenFolderItem("text")
If readFile <> Nil Then
  Dim ReadStream As BinaryStream = BinaryStream.Open(readFile, False)
  ReadStream.LittleEndian = True
  Dim writeFile As FolderItem = GetSaveFolderItem("", "")
  If writeFile <> Nil Then
    Dim writeStream As BinaryStream = BinaryStream.Create(writeFile, True)
    writeStream.LittleEndian = True
    Do Until ReadStream.EOF
      writeStream.WriteInt8(ReadStream.ReadInt8)
    Loop
    writeStream = Nil
  End If
  readStream = Nil
End If
