Applying Function Arguments As A Control/class Name

I'm not sure what verbage to use in order to describe what I'm trying to accomplish.

Let me give you a piece of code and the question will be clear.


Function addValuesToComboBox(arg1)
arg1.AddItem("one")
arg1.AddItem("two")
arg1.AddItem("three")
End Function

I would like to use this function later in the code in the form of:


addValuesToComboBox("Combobox1")
addValuesToCombobox("Combobox2")

VBA will error out with "Run-time error '424': Object required". I know I need to declare the variable arg1 as a type in order to use it in this form, but I don't know the correct data type.

I also ran across a similar issue like this where the advice was to use the Set function in the form of:


Function addValuesToComboBox(arg1)
Set arg1 = arg1.AddItem("one")
Set arg1 = arg1.AddItem("two")
Set arg1 = arg1.AddItem("three")
End Function
