UTF8 & Textbox RichTextBox

[ZeroEffect]

I would like to display a file in a textbox or RichTextbox. I how load the file but the file is encoded in UTF8 format. and some characters do not show. Like chr(0) chr(1) chr(3). Things that are not really displayed. Is there away to display these characters? I know it would be more of a "place holder" but that is what I would like.

 

Thanks

Ok I have found that null chr(0) cannot be displayed and when loading the file it stops at a null character. Any thoughts?

How are you loading the data into the control in question?

Thanks for the reply, this is how I am doing it.

 

       tbreadfromfile.Clear()
       Dim sr As New StreamReader(TextBox1.Text & ".dat", Encoding.UTF8)
       Dim data As Object = sr.ReadToEnd
       tbreadfromfile.Text = data
       sr.Close()

What is generating the file? Are you sure it is UTF-8 if it is containing invalid characters?

 

Just as an aside I would declare the variable data as a String rather than Object in your sample as ReadToEnd returns a string.

I'll make that change. I am makeing the file too.

 

       Dim sw As New System.IO.StreamWriter(TextBox1.Text & ".dat", False, Encoding.UTF8)

       Dim k As Integer = 4
       For i As Integer = 0 To holder.Length - 1
           If i = k Then
               k = k + 5
               sw.Write(Chr(0))
               sw.Write(Chr(1))
               sw.Write(Chr(2))
           Else

           End If
           sw.Write(Hex(Asc(holder.Substring(i, 1))))
           tbFinalOutput.AppendText(Hex(Asc(holder.Substring(i, 1))))

       Next
       sw.Write(Chr(0))
       sw.Close()

Out of interest what kind of data are you storing in this file? Just curios as things like Chr(0), Chr(1) etc. are generally taken to have special meanings.
