Hi!
I am trying to find out how to create an empty textfile (.txt) and add
content made of two different types of formats; string and binary, and then
save it.

The idea is to first add the "dokumentheadtext" as a string,
second to add the "documentbody" as binary by extracting the content from a
uploaded httpPostedFile (.txt or .doc for example) and convert it to binary,
third I want to be able to add the "documentfoot" as a string.

Is this possible? Anyone have any good suggestions how this is best made, or
at least some good advise?

Would be most thankful...
Regards, Diana from Sweden

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
_________________________________________________

Hope it helps, nice name Diana :-)

*lol*
Thank you so much, your suggestion was similar to what I alreday had tried
but I realized I missed out on the 'ToBase64String'...
I'll try it right away! Thanks again!
