Thread: cannot convert parameter 1 from 'char *' to 'long'

I've got this now:

Code:

bool Request::handle_requests()
{
	cout << "Started Winamp Request Handler" << endl;
	while(true)
	{
		if(!Request::winamp->CurrentPos)
		{
			if(!mysql_query(Request::mysql_conn, "SELECT * FROM e107_wa_request ORDER BY request_id ASC LIMIT 1"))
			{
				cout << "Error in selecting requests:\n" << mysql_error(Request::mysql_conn) << endl;
				return false;
			}
			
			result = mysql_use_result(Request::mysql_conn);
			row = mysql_fetch_row(result);
			
			long playlist_pos = reinterpret_cast<long>(row[1]);
			
			Request::winamp->put_PlayListPos(playlist_pos);
			Request::winamp->Play();
			
			cout << "Requesting: " << Request::winamp->GetSongTitle(playlist_pos) << "..." << endl;  						
		}
	}
	
	return false;
}

and this works

But now, I get some other errors..

I think I know how to fix this problem, just add the libmysql linker to my project. But does anyone know where I can add linkers to my project in Visual C++ 2005?
