Let's go.

Imports System
Imports System.Collections
Imports System.Drawing
Imports System.Windows.Forms
Module Module1

    Private WithEvents comboBox As ComboBox

    Sub Main()
        Dim myForm As Form = New Form With {.Text = "WinForms ComboBox HashTable Example", .ClientSize = New Size(564, 420), .BackColor = Color.LightSalmon}
        comboBox = New ComboBox With {.Location = New Point(164, 176), .DropDownStyle = ComboBoxStyle.DropDownList}
        Dim nebulae As Hashtable = New Hashtable From {{"Horse Head", "HII REGION"}, {"Black Widow", "REFLECTION NEBULAR"}, {"Ghost Head", "HII REGION"}, {"Witch Head", "PLANETARY NEBULAR"}, {"Cat's Eye", "DARK NEBULAR"}, {"Elephant's Trunk", "HII REGION"}, {"Helix", "SUPERNOVA REMNANTS"}, {"Rosette", "REFLECTION NEBULAR"}, {"Ant", "PLANETARY NEBULAR"}, {"Orion", "HII REGION"}, {"Eagle", "REFLECTION NEBULAR"}, {"Roesette", "PLANETARY NEBULAR"}, {"Bernad 68", "SUPERNOVA REMNANTS"}, {"Butterfly", "DARK NEBULAR"}, {"Snake", "DARK NEBULAR"}, {"Own", "REFLECTION NEBULAR"}, {"Ring", "SUPERNOVA REMNANTS"}, {"Pelican", "PLANETARY NEBULAR"}, {"Cone", "DARK NEBULAR"}, {"Flame", "REFLECTION NEBULAR"}, {"Bumerang", "SUPERNOVA REMNANTS"}}
        Dim bindingSource As BindingSource = New BindingSource(nebulae.Keys, Nothing)
        comboBox.DataSource = bindingSource
    End Sub

    Private Sub comboBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles comboBox.SelectedIndexChanged
    End Sub
End Module
