This is simple to perform with VBA and DAO:

Dim rs As DAO.Recordset

Set rs = CurrentDb.OpenRecordset("Select YourField From YourTable")
' or, if some criteria:
' Set rs = CurrentDb.OpenRecordset("Select YourField From YourTable Where SomeField = " & SomeNumericValue & "")
' Set rs = CurrentDb.OpenRecordset("Select YourField From YourTable Where SomeField = '" & SomeTextValue & "'")
If IsNumeric(rs!Fields(0).Value) Then
    rs.Edit
        rs.Fields(0).Value = Val(rs.Fields(0).Value) + 1
        ' or, if the field's data type is Text:
        ' rs.Fields(0).Value = LTrim(Str(Val(rs.Fields(0).Value) + 1))
    rs.Update
End If
rs.Close

You can also do this with just a simple update statement.
Example:
dbEngine(0)(0).Execute("Update OneRowTable Set SomeField=SomeField+1 Where IsNumeric(SomeField)=True")

Open in new window

i get an error says something about unable to update linked file using isam

You can only update linked Access or ODBC tables.
Linked Text files and Excel worksheets are not updatable directly; that takes some more code.
