    <p>i created a client server program that displays the MAC and ip addresses of the clients and i have a function that gets the MAC address of the computer but I'm having trouble printing the MAC address in a listbox. I created a print function that did work before but i changed the code for finding the mac address and now its not working (also i don't know if i'm calling printMACaddress in the right place). I have two list boxes - one displays the ip address the other displays the MAC address. When i click the ip address i want the MAC address of that computer to be displayed but right now its not displaying. nothing happens when i click the ip address</p> <pre><code> void CmfcServerDlg::OnLbnSelchangeListClientaddr() { bool GetMACFromIP(BYTE Address[MAX_ADAPTER_ADDRESS_LENGTH], const std::string &amp;selected_ip_adr); } void CmfcServerDlg::PrintMACaddress(unsigned char MACData[]) { CString strText; strText.Format("%02X-%02X-%02X-%02X-%02X-%02X\n",MACData[0], MACData[1], MACData[2], MACData[3], MACData[4], MACData[5]); m_ClientIdList.AddString(strText); } bool CmfcServerDlg::GetMACFromIP(BYTE Address[MAX_ADAPTER_ADDRESS_LENGTH], const std::string &amp;selected_ip_adr) { IP_ADAPTER_INFO AdapterInfo[16]; DWORD dwBufLen = sizeof(AdapterInfo); DWORD dwStatus = GetAdaptersInfo( AdapterInfo, &amp;dwBufLen); assert(dwStatus == ERROR_SUCCESS); PIP_ADAPTER_INFO pAdapterInfo = AdapterInfo; bool found = false; do { const IP_ADDR_STRING *addr_str = &amp;pAdapterInfo-&gt;IpAddressList; while(addr_str != NULL) { if(selected_ip_adr == addr_str-&gt;IpAddress.String) { found = true; break; } } if(found) { memcpy(Address, pAdapterInfo-&gt;Address, MAX_ADAPTER_ADDRESS_LENGTH); PrintMACaddress(pAdapterInfo-&gt;Address); //problem here break; } else { PrintMACaddress(pAdapterInfo-&gt;Address); pAdapterInfo = pAdapterInfo-&gt;Next; } } while(pAdapterInfo); return found; } </code></pre>

    1. CO*"I created a print function that did work before but i changed the code for finding the mac address and now its not working"* Why did you change the code for finding the MAC address if it was working?

    2. CObecause the original code was for only finding the MAC address of the current computer but i am trying to find the MAC address of any computer that connects to the server. I had the old code in the list box event handler but now i created a separate function for finding the address

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
