Application crash wen fetching "LONG" data

Question

Working on an Oracle 9i project on Windows Server 2003 platform with Microsoft VC++ 6.0. When I tried to query a table with column storing LONG data, my simple application keep crashing. The error message is: "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.". It happened whenever "l_res->next(); " was added. If this line was removed, everything is OK. Also, if I only query the integer column in the same table, there is nothing wrong. It seems fetching LONG data is not supported in OCCI, am I right? Thanks for help!
The source code is:
#include <stdio.h>
#include <iostream>
#include <string>
#include <exception>
#include <occi.h>
using namespace oracle::occi;
using namespace std;
int main(int argc, char* argv[])
     Environment* l_env = Environment::createEnvironment(Environment::DEFAULT);
     Connection* l_con = l_env->createConnection("scott", "tiger", "test1");
     Statement* l_stmt = l_con->createStatement("select col1, col2 from to_be_drop");
     ResultSet* l_res = l_stmt->executeQuery();
     //l_res->setCharacterStreamMode(2, 4000);
     cout << "status of resultset is: " << l_res->status() << endl;
     l_res->next();
     /*try
          Stream* l_stream = l_res->getStream(2);
     catch(SQLException ex)
          cout << "error no: " << ex.getErrorCode() << endl;
          cout << ex.getMessage() << endl;
     l_stmt->closeResultSet(l_res);     
     l_con->terminateStatement (l_stmt);
     l_env->terminateConnection(l_con);
     return 0;
The table is:
create table to_be_drop
     col1 number,
     col2 long
This table was populated with:
insert into to_be_drop values (1, 'this is a sunny day?!');
insert into to_be_drop values (2, 'this is a rainy day?!');
insert into to_be_drop values (3, 'this is a snowy day?!');
commit;

I found where the problem was and solved it. There are two ways to handle this kind of error.
