sender Is (control) with Option Strict On

Select Case True
    Case sender Is PrintPreviewToolStripMenuItem, sender Is PrintPreviewToolStripButton
You can use Select Case as in the following:

Select Case True
   Case sender Is TextBox1
      Label1.Text = TextBox1.Text
Case sender Is TextBox2
      Label1.Text = TextBox2.Text
End Select

However, this translates into IL (and decompiled using Reflector) as:

 Dim flag1 As Boolean = True
      If (flag1 = (sender Is Me.TextBox1)) Then
            Me.Label1.Text = Me.TextBox1.Text
            If (flag1 = (sender Is Me.TextBox2)) Then
                  Me.Label1.Text = Me.TextBox2.Text
            End If
      End If

I don’t know if this helps.
