multiple transactions


I want to use transactions in a application. This is the working code I have so far:

       Dim sqlCommand As String = "SELECT * FROM tblMyTable"

        Dim da1 As New SqlClient.SqlDataAdapter

        da1 = New SqlClient.SqlDataAdapter(sqlCommand, objConnection)

        Dim cmdClientsBuilder As New SqlClient.SqlCommandBuilder
        cmdClientsBuilder = New SqlClient.SqlCommandBuilder(da1)
        da1.InsertCommand = cmdClientsBuilder.GetInsertCommand()
        da1.DeleteCommand = cmdClientsBuilder.GetDeleteCommand()
        da1.UpdateCommand = cmdClientsBuilder.GetUpdateCommand()

        Dim txn As SqlClient.SqlTransaction = objConnection.BeginTransaction

        da1.UpdateCommand.Transaction = txn
        da1.DeleteCommand.Transaction = txn
        da1.InsertCommand.Transaction = txn

            Console.WriteLine("Insert succeeded")
        Catch ex As Exception
            Console.WriteLine("Insert Failed")
            'Optional. A Finally block is always executed when execution leaves any part of the Try statement.
        End Try

HOWEVER, I am puzzled how to use this if I had another update which I wanted to perform. For example, suppose I wanted to update another table as well e.g. dt2

            Console.WriteLine("Insert succeeded")

To do this, would I need to have two transaction objects?

Could somebody point me in the right direction, with example code, on how to do this?

Thanks in advance

You have to set the transaction property also to da2.

da2.UpdateCommand.Transaction = txn
da2.DeleteCommand.Transaction = txn
da2.InsertCommand.Transaction = txn

Beware: the transaction will rollback BOTH the updates if one of them fails.
