In Visual Basic.net I managed to get this little arrow symbol ↵ in the TextBox some time ago, but lost it.

Is this font dependent? I used Consolas and Courier New. Do i need a RichTextBox or something else?

I tried chr(10) and chr(13), environment.newline and vbLf, vbCr and what else but I'm lost.

I just want to have that special character to be visible for "debug purposes". My system is UTF capable.

The TextBox does not display unprintable characters, like most text editors can do.

You can, however, simply insert the ↵ symbol yourself, be replacing each newline character with ↵ and a newline character.

Example:

Dim f = New Form()
Dim txt = New TextBox() With { .MultiLine = True, .Dock = DockStyle.Fill}

Dim text = <text>This is just
                 some multine text
                 to be displayed</text>.Value

txt.Text = Regex.Replace(text, "(\n\r|\r|\n)", "↵$1")

f.Controls.Add(txt)
f.ShowDialog()

Result:

  • Thanks, this will do the trick! Somehow I managed to do this in some other way also but how, that remains as a mystery. (Like I mentioned I forgot the code allready) – LAamanni Sep 20 '13 at 07:22

  • My textbox is readonly and I write to it in my code. I write CR/LF to end of every line. But I can't see that symbol in the text box. I know this should be possible somehow. But normally it doesn't appear there, of course. – LAamanni Sep 19 '13 at 11:36
