Question

I have a text area and a function to do syntax highlighting on it. Right now it reads the entire RichTextBox. How would I get a string variable containing the current line? Below is the code i currently have.

Private Sub HighLight()     Dim rm As System.Text.RegularExpressions.MatchCollection     Dim m As System.Text.RegularExpressions.Match     Dim x As Integer ''lets remember where the text courser was before we mess with it      For Each pass In FrmColors.lb1.Items         x = rtbMain.SelectionStart         rm = System.Text.RegularExpressions.Regex.Matches(LCase(rtbMain.Text), LCase(pass))         For Each m In rm             rtbMain.Select(m.Index, m.Length)             rtbMain.SelectionColor = Color.Blue         Next         rtbMain.Select(x, 0)         rtbMain.SelectionColor = Color.Black     Next End Sub 

Answer 1

Not tried it but:

rtbMain.Lines(lineNumber) 

if not assign the Lines property to an array and access the array element.
