    <p>Right now I am building a scripting language (EngineScript). Currently you can only type a single command/function (IE: <code>sout "Hello world"</code>) but I want to expand it.</p> <p>So I was wondering whether you guys knew any code to get the characters typed after a newline into a separate variable in VB2012.Net. Thanks :-)</p> <p>Here is my code: </p> <pre><code>Public Class Form1 Dim strvar0 As String Dim strvar1 As String Dim strvar2 As String Dim strvar3 As String Dim numvar As Integer Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Dim first4Chars As String = TextBox1.Text.Substring(0, 4) Dim restOfChars As String = TextBox1.Text.ToString.Substring(5) Select Case first4Chars Case "sout" Select Case restOfChars Case "box:str0" TextBox2.Text = strvar0 &amp; vbCrLf &amp; vbCrLf &amp; vbCrLf &amp; vbCrLf &amp; "COMMAND //sout\\ has been successfully used" Case Else TextBox2.Text = restOfChars &amp; vbCrLf &amp; vbCrLf &amp; vbCrLf &amp; vbCrLf &amp; "COMMAND //sout\\ has been successfully used" End Select Case "str0" strvar0 = restOfChars Case Else TextBox2.Text = "Error".ToString End Select End Sub Private Sub HelpToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles HelpToolStripMenuItem.Click Dim a As New Help End Sub Private Sub RunToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles RunToolStripMenuItem.Click Button1.PerformClick() End Sub End Class </code></pre> <p>...I am doing this is a Windows form</p> <p>@Jamby when I use your code:</p> <pre><code>Public Class Form1 Dim strvar0 As String Dim strvar1 As String Dim strvar2 As String Dim strvar3 As String Dim numvar As Integer Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click For Each Line In TextBox1.Text.Split(vbNewLine) Dim first4Chars As String = TextBox1.Text.Substring(0, 4) Dim restOfChars As String = TextBox1.Text.ToString.Substring(5) Select Case first4Chars Case "sout" Select Case restOfChars Case "box:str0" TextBox2.Text = strvar0 &amp; vbCrLf &amp; vbCrLf &amp; vbCrLf &amp; vbCrLf &amp; "COMMAND //sout\\ has been successfully used" Case Else TextBox2.Text = restOfChars &amp; vbCrLf &amp; vbCrLf &amp; vbCrLf &amp; vbCrLf &amp; "COMMAND //sout\\ has been successfully used" End Select Case "str0" strvar0 = restOfChars Case "exit" Me.Close() Case "lofi" Select Case restOfChars Case "box:str0" Process.Start(strvar0) Case Else Process.Start(restOfChars) End Select Case "inet" Process.Start("iexplore.exe" + restOfChars) Case Else TextBox2.Text = "Error".ToString End Select Next TextBox1.Clear() End Sub Private Sub HelpToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles HelpToolStripMenuItem.Click Dim a As New Help End Sub Private Sub RunToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles RunToolStripMenuItem.Click Button1.PerformClick() End Sub Private Sub MenuStrip1_ItemClicked(sender As Object, e As ToolStripItemClickedEventArgs) Handles MenuStrip1.ItemClicked End Sub End Class </code></pre> <p>It does not generate errors but when I type</p> <p><code>sout Hello</code> newline <code>sout World</code></p> <p>the following should output from my output window:</p> <pre><code>Hello COMMAND //sout\\ has been successfully used World COMMAND //sout\\ has been successfully used </code></pre> <p>But instead this happens:</p> <pre><code>Hello sout World COMMAND //sout\\ has been successfully used </code></pre> <p>Help!!!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
