Either the constructor of Connection, or the Query() method throws an exception of type const char *. You can catch it, by enclosing the calls with try, and adding a catch block, like:

Code:
try {
    Connection DbConnection(Host, Database, UserId, Password);
    query="select * from the test"; // test is my database
    result = DbConnection.Query(query); // perform the required database operation..
}
catch (const char *errmsg)
{
    std::cerr << "error message from connection: " << errmsg << "\n";
    return 1;
}
