pegar ip e checar MySQL

[myNameX 0]

galera me ajuda a como verificar se o ip existe no banco de dados.

 

to tentando faz tempo, mais fala algo de char e não string

WORD wVersionRequested = MAKEWORD(1, 1);
WSADATA wsaData;
char Name[256], *ip;
PHOSTENT host;
int i;
ip = (char *)malloc(256);
WSAStartup(wVersionRequested, &wsaData);
gethostname(Name, sizeof(Name));
host = gethostbyname(Name);
ip = inet_ntoa(*(struct in_addr *)host->h_addr_list[0]);


String^ constring = L"datasource=localhost;port=3306;username=root;password=";
MySqlConnection^ conDataBase = gcnew MySqlConnection(constring);
MySqlCommand ^cmdDataBase = gcnew MySqlCommand("SELECT * FROM `blabla`.`users` WHERE IP='" + std::string(ip) + "';", conDataBase);
MySqlDataReader ^myReader;
