To read any form's text (except RichTextBox) line by line I've always used this splitting
Dim Lines() as String = Split(TextBox1.Text, vbNewLine)MsgBox(Lines(0))This code just works perfectly.But whenever I try this code on a RichTextBox like this:Dim Lines() as String = Split(RichTextBox1.Text, vbNewLine)MsgBox(Lines(0))The message box appears with the whole lines.I think maybe the RichTextBox1.Text() returns another new line character (means not vbNewLine).
I've been search and I can't found an answer that works, I need to remove (delete) the last line in a RichTextBox1 in vb .net, I mean remove last line and 'breakline' too, but only the last, no others,

I have a richtextbox control. It contains many lines of text (multiline is enabled). My goal is: When user clicks with right-click mouse, I'd like to display all the text of the line where the cursor is. I'm using this method to get the cursor's line:
Dim line As Integer = RichTextBox1.GetLineFromCharIndex(RichTextBox1.SelectionStart)

I am using VB2008 Express. In my program I have a loop that is updating variables. As these variables are updated, the updated information must be displayed in the RichTextBox.

I would like each update to be on a new line, so I need to force a new line in my code. Here is the code for part of the loop so far.[code]
