Hi

I am using the following procedure to import a text file into Access.
When I run it more than once it seems to append the new data to the existing table.
How would I change the code to rather overwrite that table?

   Sub Import_CSV_to_Access_table(ByVal oTextFilePath As String, ByVal oTableName As String, ByVal oSpecificationName As String)
        Try

          Dim arrSplit As Object = Split(Globals.ThisAddIn.oRIGHT.lblConnectionString.Text, "=")
            Dim Access_File_Path As String = Mid(arrSplit(2), 1, Len(arrSplit(2)) - 1)

            Dim appAccess As New Microsoft.Office.Interop.Access.Application

            appAccess.OpenCurrentDatabase(Access_File_Path)
            appAccess.Visible = True

            If oSpecificationName = "" Then
                appAccess.DoCmd.TransferText(TransferType:=Microsoft.Office.Interop.Access.AcTextTransferType.acImportDelim, TableName:=oTableName, _
               FileName:=oTextFilePath, HasFieldNames:=True)
            Else
                appAccess.DoCmd.TransferText(TransferType:=Microsoft.Office.Interop.Access.AcTextTransferType.acImportDelim, SpecificationName:=oSpecificationName, TableName:=oTableName, _
                FileName:=oTextFilePath, HasFieldNames:=True)
            End If

            appAccess.CloseCurrentDatabase()
            appAccess = Nothing

     Catch ex As Exception
            MsgBox(ex.Message & " poph11")
        End Try
    End Sub
