How can you cause a combobox to loose focus?

Question

I am developing a windows forms project in vb.net. I have added a comboBox to my form. the form automatically focuses on the comboBox. Nothing I click on causes the comboBox to loose focus. I do not want the form to focus on the comboBox because I do not want users to change the selected text in the comboBox by accidentally moving the scroll wheel.

I have tried:

comboBox1.CanFocus = False 
comboBox1.Focus = false

These properties are not write-able.

InvokeLostFocus(ComboBox1, New EventArgs)

This does not throw a compiler error but it does not seem to do anything either (focus stays).

I am really stuck and can not find anything on SE or google. Any help is much appreciated.

Thanks!

You need to focus another control. Note that the form itself cannot be focused.

Something like:

label1.Focus()

If this doesn't work for you, you can try this:

Private Sub Form1_Load(sender As Object, e As EventArgs)  
    Me.ActiveControl = label1;       
End Sub

You can even try to disable and enable the ComboBox.
