I really need help with this text file. When there is this weird symbols(char) or whatever we call it on a text file, it reads partial "before a" but it does not returns anything after. This txt file is only part it. The problem is I don't know when there is going to be that char in a txt file.


        Dim sr As New StreamReader(sourcedir) ', System.Text.Encoding.Unicode)

        Dim tmp As String

        tmp = sr.ReadLine
        Me.TextBox1.Text = tmp

What file? It is probably a carriage return or a line feed, without the corresponding cr/lf character (they come in pairs on windows). It can also be any other control character that is considered a newline character. It can even be any of the Unicode newline characters (0x80?), which disrupt correct reading.

You can alternatively read it character for character and create your own lines, plus filter those characters out.

you say that three times... but I think your file is not allowed. Change the extension to *.txt or something.

Well, I believe you, but something is odd about it and it doesn't upload here, which is strange, because txt files can always be uploaded, I do it all the time and quite often they're actually binary files and it goes all fine.

I'd love to help you, but I do need to have a look at that file. You can also try uploading it somewhere else and send the link here.

I figured out out.. I used peek <> -1 method  and system.text.encoding.default.  It worked.
You can close it out now.

As it turns out, this is what I suggested in my first comment, #24330447. I'll leave it up to you to award points or to accept your own comment as answer + award points... :)
