As soon as you're adding binary content, you're *not* creating a text
file, unless you're also converting the binary content to text (eg
using Base64).

Hi

I would use the System.IO.FileStream to create a buffer for a text file then
System.IO.StreamWriter to write all the data.

Transform the bytes to strings, something like:
_________________________________________________
Imports System.IO
Public Module Class1
   Dim bytes() As Byte = {0, 24, 245, 32, 32}
   Dim text As String = "Hola"

   Private testfile As String = "Test.txt"
   Public Sub Main()
       ' Create the new, empty data file.
       Dim fs As New FileStream(testfile, FileMode.Create)
       Console.WriteLine("{0} file created/overwritten", testfile)

       text &= Convert.ToBase64String(bytes)

       ' Create the writer for text.
       Dim sw As New StreamWriter(fs)
       ' Write text
       sw.Write(text)
       sw.Close()

       'Close buffer
       fs.Close()
   End Sub
End Module
