Hi Experts,

I have a problem i can get my head around.

With Notepad.exe you can open any file type as text. When i try to replicate this using streams it doesnt work.

I only shows about 5 of the characters.

How would i be able to to achieve this?

Cheers,

Tom

What are you trying to replicate it in?  Most of the controls that display text in VB.NET - e.g textbox, messagebox, label - stop reading as soon as they encounter a Null - Chr(0).  Non-text files usually have lots of those in them.  You will probably have to use a .Replace of some sort to change any Nulls to something else before you can display it.

when i read the stream using a streamreader, it only gets the first few characters when using the readtoend function.

Try this.  Imports System.IO.  One form. One button.  One OpenFileDialog.  One RichTextBox.  

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        OpenFileDialog1.ShowDialog()
        Dim filename As String = OpenFileDialog1.FileName
        Dim sr As New StreamReader(filename)
        Dim s As String = sr.ReadToEnd
        sr.Close()
        Dim displaytext As String = s.Replace(Chr(0), Chr(126)) ' replaces Null with ~
        RichTextBox1.Text = displaytext
    End Sub
