This example uses the ActualSize and DefinedSize properties to display the defined size and actual size of a field.
Public Sub ActualSizeX()
Dim rstStores As ADODB.Recordset
Dim strCnn As String
' Open a recordset for the Stores table.
strCnn = "Provider=sqloledb;" & _
"Data Source=srv;Initial Catalog=pubs;User Id=sa;Password=; "
Set rstStores = New ADODB.Recordset
rstStores.Open "stores", strCnn, , , adCmdTable
' Loop through the recordset displaying the contents
' of the stor_name field, the field's defined size,
' and its actual size.
rstStores.MoveFirst
Do Until rstStores.EOF
MsgBox "Store name: " & rstStores!stor_name & _
vbCr & "Defined size: " & _
rstStores!stor_name.DefinedSize & _
vbCr & "Actual size: " & _
rstStores!stor_name.ActualSize & vbCr
rstStores.MoveNext
Loop
rstStores.Close
End Sub
