Public Function getDataType(v As Variant) As String
    Select Case VarType(v)
        Case vbArray
        getDataType = "vbArray"
        Case vbBoolean
        getDataType = "vbBoolean"
        Case vbByte
        getDataType = "vbByte"
        Case vbCurrency
        getDataType = "vbCurrency"
        Case vbDataObject
        getDataType = "vbDataObject"
        Case vbDate
        getDataType = "vbDate"
        Case vbDecimal
        getDataType = "vbDecimal"
        Case vbDouble
        getDataType = "vbDouble"
        Case vbEmpty
        getDataType = "vbEmpty"
        Case vbError
        getDataType = "vbError"
        Case vbInteger
        getDataType = "vbInteger"
        Case vbLong
        getDataType = "vbLong"
        Case vbNull
        getDataType = "vbNull"
        Case vbObject
        getDataType = "vbObject"
        Case vbSingle
        getDataType = "vbSingle"
        Case vbString
        getDataType = "vbString"
        Case vbUserDefinedType
