Isn't it disturbing, that you have to select the database driver interactively? To stop it change the first part of your code:
Example 3-1. Preselect the driver and user information
1 #include <hk_classes.h> 2 #include <iostream> 3 int main() 4 { 5 hk_drivermanager* mydrivermanager = new hk_drivermanager(); 6 if (mydrivermanager==NULL) {cout <<"error creating mydrivermanager"<<endl;exit(1);} 7 hk_connection* myconnection = mydrivermanager->new_connection("mysql"); 8 if (myconnection==NULL) {cout <<"error creating myconnection"<<endl;exit(1);} 9 myconnection->set_host("localhost"); 10 myconnection->set_user("root"); 11 myconnection->set_password("mypasswd"); 12 myconnection->connect(); 13 . 14 . 15 . |
