VB.NET Read current line in a text area?
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
Not tried it but:
if not assign the Lines property to an array and access the array element.
