Need advice for Parent Child insert in transaction mode

P: n/a

I have Parent child table as decribe below:
Parent Table name = TESTPARENT
1. counter bigint isIdentity=Yes Increment=1 Seed=1
2. customer nChar(10)
Child Table name = TESTCHILD
1. counter bigint
2. qty numeric(3,0)

I want to insert new record with code below:
void button1_Click(object sender, EventArgs e)
// Define object to catch @@indentity
object myCounter;
// Connect to database & open
myConnection = new SqlConnection("Data Source=54ND1\\SQL2005;Initial
Catalog=Axioma;User ID=sa; Password=sandi");
// define transaction
SqlTransaction myAtom = myConnection.BeginTransaction();
SqlCommand myAtomCmd = myConnection.CreateCommand();
myAtomCmd.Transaction = myAtom;
// Start insert to database with transaction mode
// Insert parent new record
myAtomCmd.CommandText = string.Format("insert into TESTPARENT
(customer) values ('{0}')", tbCustomer.Text);

// Get Indentity
myAtomCmd.CommandText = "SELECT @@identity from
myCounter = myAtomCmd.ExecuteScalar();
// insert child new record
myAtomCmd.CommandText = string.Format("insert into TESTCHILD
(counter, qty) values ('{0}', {1})",
Convert.ToInt64(myCounter.ToString()), tbQty.Value);

// Commit transaction
MessageBox.Show("Data not inserted");
I already try with 2 workstation and 1 server, that code working well
(not duplicate in parent and insert right relation child parent record
in child table ).
If, i run with many many user, I am not sure that code will stay
Please advice, that code is the right way to archieve parent child
relation insert table??
I using C# and SQl Server 2005
Thank,s and regards
