Copy part of text from richtextbox (Split)

[AnooooPower]

I want to outpout part of a richtextbox content to a textbox.

Exemple (This is just part of the richboxtext1:

<meta http-equiv="refresh" content="0;url=?sid=defd7592f5b806ad8a4fa1273bd73077">		<

This is code i used but is faulty :(
:

Dim strBuild As String = Nothing
        strBuild = Split(Split(RichTextBox1.Text, "sid=")(1), "''>")(0)

        TextBox6.Text = strBuild

I want whats between "sid=" and the "''>"
sid=defd7592f5b806ad8a4fa1273bd73077">

Dim strS As String() = Nothing
            Dim actaulstring As String = ""
            strS = RichTextBox1.Text.Split("=")
            actaulstring = strS.GetValue(1)
            strS = actaulstring.Split(">")
            actaulstring = strS(0)
            TextBox2.Text = actaulstring

This only copies:

h" content="0;url=?

From:

<meta http-equiv="refresh" content="0;url=?sid=defd7592f5b806ad8a4fa1273bd73077">

Note that i did edit the tags to "sid=" and "''>"

Dim strS As String() = Nothing
            Dim actaulstring As String = ""
            strS = RichTextBox1.Text.Split("=")
            actaulstring = strS.GetValue(2)
            strS = actaulstring.Split(">")
            actaulstring = strS(0)
            TextBox2.Text = actaulstring

Dim start As Integer = 1
            Dim F1 As Integer
            Dim F2 As Integer
            F1 = InStr(start, RichTextBox1.Text, "sid=")
            F2 = InStr(F1 + 1, RichTextBox1.Text, """>")
            If F2 = 0 Then F2 = Len(RichTextBox1.Text)
            TextBox6.Text = (Mid(RichTextBox1.Text, F1, F2 - F1))

Solved.

Not really sure, but I believe that "Len" is from vb6 and might cause issues in the future when used as code in vb.net.
If "Len" is length, then use RichTextBox1.Text.Length .

As for your already solved issue, see if this helps.

Dim iStartIndex, iEndIndex As Integer
        With RichTextBox1.Text
            iStartIndex = .IndexOf("sid=") + 4
            iEndIndex = .IndexOf(""">", iStartIndex)
            MsgBox(.Substring(iStartIndex, iEndIndex - iStartIndex))
        End With

Oh wow this works perfect, thanks coderorder.
