I am trying to implement line by line scrolling on my richtextbox - Here is the initial code which I think is incomplete and doesnt work.I have VB 2010 Express?
Class RichTextBox1
Inherits RichTextBox
Private Const WM_SCROLL As Short = &H20A
[code]....
I am new to programming- basically I have a richtextbox1 with some data from the database,but when you scroll it scrolls 3 lines, whereas I want to scroll only one line at a time.

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
RichTextBox1.Focus()

View 1 RepliesTo 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'd like to do something I thought was simple. All I'd like is to take the data from a connected database, then put those values into a scrolling line graph. Preferabley with 4 lines (taking information from separate tables) on the same graph. I've connected the database and set up a script to populate it with data, but that's as far as I go with graphs.
I've downloaded 'MSChart.exe', 'MSChart_VisalStudioAddOn.exe', ChartFXLiteNet' and others, yet none work. I've also followed a tutorial here on graphs, but it's for visual studio 2005, and I don't have the options required. I'm using Visual Studio 2008 with VB.NET.
