Hi, I have a program that reads data from a binary file, 4kilobytes at a time (using INPUT). My problem is, when i close that file and open a new file to do the same, the program does not start from the beginning of the file, and just reacts as if it has reached the end of the file. How can i tell it to begin reading from the beginning of the file again? Heres my code:

Earlier in the code, a file is opened with the following line:
  Open CD.FileName For Binary As #1
  FileSize = FileLen(CD.FileName) / 4096


The following code is then executed everytime i want the next 4k of data from that file:

 cmdSend.Enabled = False
 Dim DataChunk As String
 If FilePos < FileSize Then
  FilePos = FilePos + 1
  DataChunk = Input(4096, #1)
  Ws.SendData DataChunk
  lblConnection = "Transferring... " & Math.Round((FilePos / FileSize * 100), 0) & "%"
  DoEvents
 Else
  Ws.SendData "FileEnd" & FileLen(CD.FileName)
  FilePos = 0
  cmdSend.Enabled = True
  Close#1
 End If

Open CD.FileName For Binary As #1
Seek #1, 1 '<-- add this line
