Cache and Visual .net problem

[jalil]

Hi everybody,
I have a problem when I try to connect .Net and cache, is there any 
settings to do like Visual6 and cache.
When I connect Cach� to Visual c++ 6 it work correctly but if I export 
my Visual6 project to .Net it doesn't work.

Please help me.
Thanks jalil.
here is the code:
#include <cppbind.h>
int main()
{
	
	try{
	// establish the physical connection to Cache'
	Db_err conn_err;
	d_connection conn = tcp_conn::connect("localhost[1972]:VIDB","_SYSTEM", 
"SYS", &conn_err);
	if (conn->is_connected())
	{
		std::cout << "Connection Suceeded "<<'\n';
	}
	else
	{
		std::cout <<"Connection failed" << '\n';
	}

     return 0;
                // all objects are closed automatically
        }
        catch(const Db_err& err) {
                std::cerr << err << '\n';
                return -1;
        }
}
