How to catch SQL Exception in ASP?

I have make a SQL Statement to insert into db:

strSQL = "insert into lgr_logreg values(" + strUI + ",'" + strPassword + "','" + strEmail + "','" &_
 strTel + "','" + strRank + "','" + strPosition + "','" + strFullname +"','" + strRemoteIP + "','2001-07-01','test');"

This is true that sometimes the user will insert duplicated Primary Key Value. So, how can catch the SQL exception of ASP or can i test the statement to return boolean for me ? like

trueOrFalse = connection.Execute(strSQl)

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC SQL Server Driver][SQL Server]Violation of PRIMARY KEY constraint 'PK_lgr_logreg'. Cannot insert duplicate key in object 'lgr_logreg'.
/regpoint.asp, line 33


Please give me some code example. Thanks!

Howe about putting in some transaction management in the database and use raiserror when an exception occurs. You could code your insert statment into a server side stored procedure ?
