[2008] RichTextBox does not allow newlines&backspace throws cursor into end of text.

Hi,

I have a RichTextBox control and this Form code:

Imports System.Text.RegularExpressions
 
Public Class Form1
    Private Sub RichTextBox2_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RichTextBox2.TextChanged
        Dim text As String
        text = RichTextBox2.Text
 
        Dim re As New Regex("(bold)")
        text = re.Replace(text, "{\b $1}")
 
        text = "{\rtf1\ansi{\fonttbl\f0\fswiss Helvetica;}\f0\pard " & text & "}"
 
        RichTextBox2.Clear()
        RichTextBox2.SelectedRtf = text
    End Sub
End Class

If you try it, you will notice that it works nicely for word 'bold' but if u try to backspace (remove) anything in the middle of the text, it throws the cursor back to end...

Also, the Enter key for newlines is not working. Help?

u should not exchange the whole text each time.
the best, i think is, only to change the word which is just written. This is quit complicated, but it reduces flickering.

It seemed to me on http://geekswithblogs.net/pvidler/ar...10/14/182.aspx there are very efficient approaches published. Dont worry about c#, u can use a codeconverter, eg http://codeconverter.sharpdevelop.ne...Converter.aspx
