my little suggestions: char szhostname[128]; //gethostname if( gethostname(szhostname, 128) == 0 ) { // get ipaddr. struct hostent * phost; phost = gethostbyname(szhostname); } //and refer to msdn Hello World!

see: // TODO: Add extra validation here CString strTemp; struct hostent *host; struct in_addr *ptr; // To retrieve the IP Address DWORD dwScope = RESOURCE_CONTEXT; NETRESOURCE *NetResource = NULL; HANDLE hEnum; WNetOpenEnum( dwScope, NULL, NULL, NULL, &hEnum ); WSADATA wsaData; WSAStartup(MAKEWORD(1,1),&wsaData); if ( hEnum ) { DWORD Count = 0xFFFFFFFF; DWORD BufferSize = 2048; LPVOID Buffer = new char[2048]; WNetEnumResource( hEnum, &Count, Buffer, &BufferSize ); NetResource = (NETRESOURCE*)Buffer; char szHostName[200]; unsigned int i; for ( i = 0; i < BufferSize/sizeof(NETRESOURCE); i++, NetResource++ ) { if ( NetResource->dwUsage == RESOURCEUSAGE_CONTAINER && NetResource->dwType == RESOURCETYPE_ANY ) { if ( NetResource->lpRemoteName ) { CString strFullName = NetResource->lpRemoteName; if ( 0 == strFullName.Left(2).Compare("\\\\") ) strFullName = strFullName.Right( strFullName.GetLength()-2); gethostname( szHostName, strlen( szHostName ) ); host = gethostbyname(strFullName); if(host == NULL) continue; ptr = (struct in_addr *) host->h_addr_list[0]; // Eg. 211.40.35.76 split up like this. int a = ptr->S_un.S_un_b.s_b1; // 211 int b = ptr->S_un.S_un_b.s_b2; // 40 int c = ptr->S_un.S_un_b.s_b3; // 35 int d = ptr->S_un.S_un_b.s_b4; // 76 strTemp.Format("%s --> %d.%d.%d.%d", strFullName,a,b,c,d); AfxMessageBox(strTemp); } } } delete Buffer; WNetCloseEnum( hEnum ); } WSACleanup(); //******************************************* I try ,but fail ! thanks all the same !
