ExecuteNonQuery and ExecuteScalar does not return or throw an error when executing stored proc

I have a SQLEXPRESS database.  I am using C# and ADO.net to call a stored procedure.  The SQL Stored Procedure has been tested and works as expected.

When the code executes the stored procedure is not called, there is no exception and no error.

I tried the same code with ExecuteScalar() but no difference.

Does anyone see an issue with the code below?




private void InsertTGroup(string strTEntry)
        {
            int          nRetCode = 0;
            
            // Build a connection string...
 
            SqlConnectionStringBuilder objConnString = new SqlConnectionStringBuilder();
 
            objConnString.InitialCatalog = "TGroups";
            objConnString.DataSource = @"(local)\SQLEXPRESS";
            objConnString.IntegratedSecurity = true;
            
            SqlConnection objSqlConn = new SqlConnection(objConnString.ConnectionString);
 
            using (SqlCommand objSqlCmd = 
                        new SqlCommand("InsertTGroup", objSqlConn))
            // -----------------------------------------------------------
            {
                try
                {
 
                    objSqlCmd.CommandType = CommandType.StoredProcedure;
 
                    // Input parameter
 
                    SqlParameter objSqlParam = new SqlParameter();
 
                    objSqlParam.ParameterName = "@strGroupName";
                    objSqlParam.SqlDbType = SqlDbType.NVarChar;
                    objSqlParam.Size = 120;
                    objSqlParam.SqlValue = strTEntry;
                    objSqlParam.Direction = ParameterDirection.Input;
 
                    objSqlCmd.Parameters.Add(objSqlParam);
 
                    nRetCode = objSqlCmd.ExecuteNonQuery();
                }
                catch (SqlException e)
                // -------------------------------------------------------
                {
                    Console.WriteLine(e.Message);
 
                }
 
            }
 
            objSqlConn.Close();
 
        }

you never open the connection:
 
SqlConnection objSqlConn = new SqlConnection(objConnString.ConnectionString);
objSqlConn.Open();  // should be inside the try catch ...
