c# database help

I've been working on this for days. I can't seem to insert into my access db. here is my code. When the code is run, the "YEAH!!!" message is displayed, but no new record in the db. Any help would be fantastic.


string conString ="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\\BT1.mdb;providerName=System.Data.OleDb";
OleDbConnection BoardConnection = new OleDbConnection(conString);

try
{

OleDbCommand cmd = new OleDbCommand("INSERT INTO tblBoards (BoardName, BoardSerial, BoardOpened, EmpOpened, BoardPos) values (@BoardName, @BoardSerial, @BoardOpened, @EmpOpened, @BoardPos)", BoardConnection);



cmd.Parameters.Add("@BoardName", OleDbType.VarChar).Value = varBoardNames;
cmd.Parameters.Add("@BoardSerial", OleDbType.VarChar).Value = varBoardSers;
cmd.Parameters.Add("@BoardOpened", OleDbType.DBDate).Value = varBoardOpen;
cmd.Parameters.Add("@EmpOpened", OleDbType.VarChar).Value = "mike";
cmd.Parameters.Add("@BoardPos", OleDbType.Integer).Value = varBoardPos;


BoardConnection.Open();
int numRows = cmd.ExecuteNonQuery();
BoardConnection.Close();
if (numRows == 1)
{

MessageBox.Show("YEAH!!!");
}
else
{

MessageBox.Show("****");
}


}
catch (Exception e)
{ }

finally
{
if (BoardConnection != null)
{
BoardConnection.Close();
}
}

This doesn't return any rows

Code:

---

int numRows = cmd.ExecuteNonQuery();

---

You'll have to check afterwords to see if its there.

I wonder about the |Data Directory| statement

Code:

---

string conString ="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\\BT1.mdb;providerName=System.Data.OleDb";
