VS 2008 - How To Get Text By Line From RichTextbox
Jun 20, 2009
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)
But how do I get the text of the line? Should I copy the whole text to a string array , and then just print the relevant line item?

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 have a RichTextBox in a VB2008 Windows Form application. The RichTextBox has tabs set at 250 and 400. The following code snippet is used to populate the RichTextBox using the result of a LINQ query.
rtbData.AppendText(String.Format("{0}.
{4}{1}. {4}{2}{3}", strTitle, strAuthor, strBook, ControlChars.CrLf, ControlChars.Tab))
I've noticed that most of the time it takes several mouse clicks to highlight a desired line of text in the RichTextBox. Is there some code that will allow selecting the entire line that a user clicks on? The length each line in the RichTextBox is not the same.

Going in more depth currently over on MSDN on how to parse a color line to the richtextbox.
To explain more imagine you have various types of information. For example sake say a....
PRIVMSG
NOTICE
MODE
being parsed to the richtextbox. Now we have one sub to deal with all these three messages from the server but each needs it's own color.
Now currently i can only think about on each arrival of a new message loop the RTB length and match a a string.
Is there any way when we append to the RTB with the new string we can parse that new strings color also?

When i am receiving server responses some are to long for the RTB so obviously continue on the next line. Each line is time stamped. If the word is to long it looks as follows:
15:00 this is a long
message
15:01 another message and so on
what i would like is for the new line to be indented to under the text above so it does not wrap directly under the time stamp. [Code]

I would like for my program to open up a new form (It will be in Form4 webbrowser) and the form will navigate via the text line that was double-clicked in a RichTextBox1. Here is an illustration showing what I'm trying to accomplish:
Here is the code that I have so far:
Private Sub RichTextBox1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox1.MouseDoubleClick
Form4.Show()
Form4.WebBrowser1.Navigate("http://www.google.com/search?q=" & "THIS IS THE AREA OF CODE THAT I NEED TO MAKE THE RICHTEXTBOX1 CLICKABLE!!!" )
End Sub

I am reading text from a file (*.TXT) 1 line at a time using streamreader. As I read that input, I am looking for specific starting and ending character strings ("<" and ">") . When I find those strings, I would like to select the characters between those string and have it set to BOLD and BLUE before appending that input line to the contents of a richtextbox.The only way I have found to do this is to first append the input line to the richtextbox then use the richtextbox.selection (color and font) methods to change the text.

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

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. Everything works fine and I can display my first line of data, but then the next time the second line of data overwrites the first line. 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]

The following code selects a line ina richtextbox. It works OK expect from one problem:
When a line is biger than the size of the richtextbox, it wraps it. This create a big problem as I can not select the last line of the richtextbox (when a line is wrapped it becomes two lines). When I set wordwrap to off it works just fine
Private Sub RichTextBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox1.MouseMove
