Some Notes on the Len() Function

In VB, function Len() is mainly used to return the length of a string. However, if you pass something other than a string type variable as its argument, the result may be different. For example, test the following code:
Public Sub TestLen()
    Dim sVal As String
    Dim lVal As Long
    Dim iVal As Integer
    Dim dVal As Double
    Dim vVal As Variant
