I need a VBA event to call a function with parameters

What's the VBA syntax (in Excel 2007) to have an event call an internal VBA function I will write, passing in a few parameters. I want to resuse that function for  multiple events and to use the input parameter to differentiate calls to the same function from various events?

Thanks.

Write the function like so:

Public Function Foo(ByVal RequestCode As Long, ByVal Variable1 As Variant, ByVal Variable2 As Variant) As Variant

    Select Case RequestCode
        Case 1:
            ' Do this
        Case 2:
            ' Do that
    End Select

End Function

Like so:

Public Sub SomeEventHandler()

    Dim MyResult As Variant

    MyResult = Foo(1, "A", 100)

End Sub

"As Variant" defines the variable as a variant data type which means it can store any type of value.

You can also define a variable as Long, String, Date, an array, a collection, or any of many other types.
