How to extract Access table schema with decimal places on numeric fields?

In a VBA module within an Access database I am trying to create a query which needs the schema information for a table. I can get the field names, type and size but cannot get the decimal places for the various numeric types. Anyone have a clue how to get the field properties as seen in design mode?

Following are a couple of failed tries which do not give me the decimal places for the various fields.
Code:
Private Function GetSchema1(tcTable As String)
Dim oDatabase As Database, oTabledef As TableDef
Set oDatabase = CurrentDb()
Set oTabledef = oDatabase.TableDefs(tcTable)

For Each oField In oTabledef.Fields
   a = 1
Next oField
End Function

Code:
Private Function CreateSQL(tcTable As String)
Dim cSQL As String, oDatabase As Database, oRecordset As Recordset
cSQL = "SELECT * FROM " + tcTable + " WHERE 1=0"
Set oDatabase = CurrentDb()
Set oRecordset = oDatabase.OpenRecordset(cSQL, dbOpenDynaset)
Dim iFields As Integer, oField As Object, cFieldName As String
For iFields = 0 To oRecordset.Fields.Count - 1
   Set oField = oRecordset.Fields(iFields)
   With oField
   cFieldName = .Name
   Select Case .Type
   Case Is = dbBigInt
   End With
Next iFields
End Function
TIA, Mark
 
Your code needs...
Code:
For iFields = 0 To oRecordset.Fields.Count - 1
   Set oField = oRecordset.Fields(iFields)
   With oField
      cFieldName = .Name
      Select Case .Type
         Case Is = dbBigInt[b]
      End Select[/b]
   End With
Next iFields

Some field properties such as format are not available until after you have set them.

You can do a simple test to find properties with code like the following which is not meant for production and will error out if allowed.

Code:
Sub PrintProperties(strTable As String, strField As String)
    Dim db As DAO.Database
    Dim td As DAO.TableDef
    Dim fd As DAO.Field
    Dim intProp As Integer
    On Error Resume Next
    Set db = CurrentDb
    Set td = db.TableDefs(strTable)
    Set fd = td.Fields(strField)
    For intProp = 1 To fd.Properties.Count
        Debug.Print fd.Properties(intProp).Name, fd.Properties(intProp).Value
    Next
    Set fd = Nothing
    Set td = Nothing
    Set db = Nothing
End Sub
