I am having trouble implementing transactions.. Here's my code..
-----
Dim myConnection As OleDbConnection
Dim myCommand As OleDbCommand
Dim myReader As OleDbDataReader
Dim transaction As OleDbTransaction
myConnection = New OleDbConnection(connStr)
myConnection.Open()
transaction = myConnection.BeginTransaction()
Try
myCommand.Transaction = transaction
sql = "insert into table values (1,2)"
myCommand = New OleDbCommand(sql, myConnection)
myCommand.ExecuteNonQuery()
sql = "insert into table2 values (3,4)"
myCommand = New OleDbCommand(sql, myConnection)
myCommand.ExecuteNonQuery()
transaction.commit()
Catch ex As Exception
display ex.Message and ex.ToString
transaction.rollback()
End Try
myConnection.Close()
----------
The error I get is
Execute requires the command to have a transaction object when the
connection assigned to the command is in a pending local transaction.
The Transaction property of the command has not been initialized.
System.InvalidOperationException: Execute requires the command to have a
transaction object when the connection assigned to the command is in a
pending local transaction. The Transaction property of the command has

What am I doing wrong?
