To populate a ComboBox with images from resources :

   For Each dicEntry As DictionaryEntry In resourceSet.OfType(Of Object)()
        If TypeOf (dicEntry.Value) Is Drawing.Image Then
            ComboBox1.Items.Add(dicEntry.Key.ToString())              
        End If
   Next

To select the image and set it to a PictureBox :

 Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
     Dim comboBox As ComboBox = CType(sender, ComboBox)
     Dim sSelectedItem = CType(comboBox.SelectedItem, String)
     Dim img As Image = CType(My.Resources.ResourceManager.GetObject(sSelectedItem), Image)
     PictureBox1.BackgroundImage = img
 End Sub

Is there a way to specify a folder inside resources folder? – Shan Jun 15 '19 at 17:12 — Shan, Jun 15 '19 at 17:12

There are a few things to address here. Most importantly, Image objects don't have a name, so there's nothing to list. Maybe you mean the names of the files that the Image objects were created from, but that's something different. You won't be able to get those from the PictureBox controls unless you set the ImageLocation properties to load the files. Assuming that you have done that, you could get the name of each file from the PictureBoxes like this:

Dim fileNames = Controls.OfType(Of PictureBox)().
                         Select(Function(pb) IO.Path.GetFileName(pb.ImageLocation))

That still doesn't really make sense though. It seems like getting the names of the files before loading the Images would make more sense. You haven't really explained enough to provide a confident solution though.

Your update is of no value. There's no indication of what the relationship is between the list of names you have displayed and the `Images` you describe. You've addressed nothing that I raised in my answer. — jmcilhinney, Jun 15 '19 at 16:18
