With VB6 and NT4
When y create a application with ADODC object and y associate  a DATEGRID
object

Exemple :

With Data_Ado'-------------------- Is a ADODC object
    If .ConnectionString = "" Then
        .ConnectionString = "Provider=Microsoft.Jet.OLEDB.3.51;Data Source="
+ FileTemp
        .RecordSource = "SelectPreview"
    End If
    .Refresh
End With
With Data_Preview '------------- Is a DATAGRID object
    Set .DataSource = Data_Ado
    .DefColWidth = 0
   .Refresh
End With

The application create a file .LDB

When y deconnect the ADO object in this methode :

With Data_Preview
    Set .DataSource = Nothing
End With
With Data_Ado
    .RecordSource = ""
    .ConnectionString = ""
End With

And y want kill a FileTemp => It's not possible

How do y want ?
