Excel VBA: how to cast a generic control object into a ComboBox object?

I need to cast a generic VBA form control object into a ComboBox object so that I can add items to it. The generic object won't allow me to insert items into my existing lists ``` Dim ctlCurrent As MSForms.Control For Each ctlCurrent In frmItemInput.Controls If TypeName(ctlCurrent) = "ComboBox" Then Dim lbCurrentComboBox As MSForms.ComboBox lbCurrentComboBox = ctlCurrent 'This is where the error occurs, when I try to convert one into another ' Adiciona os itens necessários lbCurrentComboBox.AddItem ("R") lbCurrentComboBox.AddItem ("D") End If Next ctlCurrent ``` My problem is: I have tons of ComboBoxes in my form and I need to add the same options for all of them. So I would like to do this progrmatically.
