Rich Text Box to Variable

I have incoming messages from a socket client going into a rich text box. Is there a way to find a part of a string and then extract x amount of characters out of that line into a variable?

Example:

I send a <T> command to the unit
I send a <V> command to the unit

the unit responds into the RTB
<TXXXX>
<VXXXX>

(XXXX could be any combination of numbers)

I need to get the TXXXX and put it in 1 variable and put the VXXXX into another variable.

it'll be easier to intercept it before it gets in to the rtb

here's an example using regex:

vb Code:

Dim testStr As String = "<T1234>" & Environment.NewLine & "<V5678>"
 
Dim rx As New Regex("(?<=\<T).+?(?=\>)")
MsgBox(String.Format("T{0}", rx.Match(testStr).Value))
 
rx = New Regex("(?<=\<V).+?(?=\>)")
MsgBox(String.Format("V{0}", rx.Match(testStr).Value))

don't forget to import regex:

vb Code:

Imports System.Text.RegularExpressions

That would be so much easier, I do not like RTB. RegEx is already installed with VS2008 correct? I am new to VS2008.

yes regex is installed. to use my code you need to import it as i recommended

this is where you put imports statements. at the top line of your form or class:

vb Code:

Imports System.Text.RegularExpressions
 
Public Class Form1
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
    End Sub
 
End Class

vb Code:

Here is how my message are received, how do I intercept them?
 
    Private Sub appendText1(ByRef incomingMessage1 As String)
        rtbR1.Clear()
        'Delegates.RichTextBoxes.appendText(Me, rtbDebug, incomingMessage1)
        Delegates.RichTextBoxes.appendText(Me, rtbR1, incomingMessage1)
 
        If frmMain.lbStations.SelectedIndex = 1 Then
            Delegates.RichTextBoxes.appendText(frmMain, frmMain.rtbMain, incomingMessage1)
        End If
 
    End Sub

it looks like incomingMessage1 is the text in 2 parts

From what I understand from the code I manipulated, I have to use the delegates command to be able to see the message coming in and RTB is the only option I can see. I could be wrong and I hope I am... Here is the code I use to connect, you can see where I define it.

vb Code:

Try
            AddHandler readerSock1.IncomingData, AddressOf appendText1
 
            readerSock1.Connect(arrIP.Item(0), arrPort.Item(0))
 
            If readerSock1.isConnected Then
                rtbDebug.AppendText("Reader 1 Connected" & vbCrLf)
            Else
                rtbDebug.AppendText("Reader 1 NOT Connected" & vbCrLf)
            End If
        Catch ex As Exception
            rtbDebug.AppendText(ex.Message)
        End Try

The addressOf command I am not to familiar with. Maybe there is a better command?
