    Hi, I'm trying to update a tabledef programatically, using
    field descriptions that exist as text in another table. I
    can't find anyway to set or reference the field's
    description property via VBA. Is this possible?

    Thanks,
    Kate

    The Description property doesn't actually exist until you add a description.
    If you try to refer to the Description property before then, you'll get an
    error 3270 (Property Not Found)

    You can use the CreateProperty method to add it in the first place.

    Here's some untested air-code that should create the description if it
    doesn't exist, or change it if it does.

    Sub SetDescription(WhatField As DAO.Field, NewDescription As String)
    On Error GoTo Err_SetDescription

    Dim prpDesc As DAO.Property

    WhatField.Properties("Description") = NewDescription

    End_SetDescription:
    Exit Sub

    Err_SetDescription:
    If Err.Number = 3270 Then
    Set prpDesc = WhatField.CreateProperties( _
    "Description", _
    dbText, _
    NewDescription)
    WhatField.Properties.Append prpDesc
    Else
    MsgBox "Error " & Err.Number & " (" & _
    Err.Description & ") occurred."
    End If
    Resume End_SetDescription

    End Sub
