See if this helps for the TrackBar.
1 MenuStrip(MenuStrip1)

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim myTrackBar As New TrackBar '// Declare New TrackBar.
        myTrackBar.Minimum = 12 : myTrackBar.Maximum = 25 '// Customize.
        AddHandler myTrackBar.Scroll, AddressOf TrackBar_Scroll '// Give it a Event to Handle.
        Dim myCtlHost As New ToolStripControlHost(myTrackBar)
        MenuStrip1.Items.Add(myCtlHost) '// Add to Main Menu.
        '// OR...
        'FileToolStripMenuItem.DropDownItems.Add(myCtlHost) '// Add to DropDownItems.
    End Sub

    Private Sub TrackBar_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) ' Handles TrackBar1.Scroll
        Dim trk As TrackBar = CType(sender, TrackBar)
        Me.Text = trk.Value.ToString '// For testing.
    End Sub
End Class

If "numeric dropdown" is a ComboBox, right click Menu and view attached image.

Again and again you made it work! And easy! Thanks so much.

Btw, by Numeric Dropdown, I mean this (I've mentioned it wrong, sorry.)
