How to return the field type and field size of a table

I am trying to determine the data type and size of fields in a specified table.
I am using the following code to return the list of fields in the table and write the information to table "TableFieldNames"

        Dim fld As DAO.Field
        Dim db As DAO.Database
        Dim rs2 As DAO.Recordset

        Set db = OpenDatabase(txtdatabasename)    
        Set rs2 = Currentdb.OpenRecordset("TableFieldNames")
        Currentdb.Execute ("DELETE TableFieldNames.* FROM TableFieldNames")

        For Each fld In db.TableDefs(cmbTable).Fields
              rs2.AddNew
              rs2!NamofTable = cmbTable
              rs2!NameOfField = fld.Name
              rs2!TypeofField = ??????????
              rs2!SizeofField = ?????????
              rs2.Update
        Next fld
        rs2.close

In rs2!TypeofField I want to put the specified data type for the field (Text, Number, Date/Time, etc.)
If the data type is Text or Number I want to put the specified field size in rs2!Sizeoffield (255, integer, double, etc.)
Is this doable?

use

              rs2!TypeofField = fld.type
              rs2!SizeofField = fld.size

I tried using fld.type and fld.size but what I get is numbers.
For example, a field that has a data type of "Text" returns a "10" for the field type.  The field size returns correctly.
A field with a data type of "Number" and a field size of "Double" returns "7" for the datatype and "8" for the field size.
Is there a way to return the actual data type and size as it shows in the field properties of the table?
