Hi Guys

Just need a quick hint with fixing a Check for Listbox contains value statement.

The code below does not return my Msgbox as it should.

Dim MyService As New ListView
        MyService.Text = NewServiceTextBox.Text
        If ListBox12.Items.Contains(MyService.Text) = True Then
            MsgBox("Service Exists")
        End If

FindbyValue is not a member of "System.Windows.Forms.ListBox.ObjectCollection

I see...
Dim MyService As New ListView
        MyService.Text = NewServiceTextBox.Text
        If ListBox12.Items.IndexOf(MyService.Text) >= 0 Then
            MsgBox("Service Exists")
        End If
