    <p><strong>i am trying to get the MAC address of another computer</strong> using a server and client program in c++ using UDP connections. The server is on one computer (it contains 2 listboxes, 1 for the IP addresses of connected clients, the other for the MAC address) the client is on another computer. my current code only gets the MAC address if i run the server and client and the same computer. When i debug the program i see that when trying to get the MAC address of another computer the program doesn't go into the if statement and run the line PrintMACaddress(pAdapterInfo->Address);</p> <pre><code> void CmfcServerDlg:: PrintMACFromIP(const CString &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;// Contains pointer to current adapter info bool found = false; do { const IP_ADDR_STRING *addr_str = &amp;pAdapterInfo-&gt;IpAddressList; if (addr_str != NULL) { if (selected_ip_adr == addr_str-&gt;IpAddress.String) { PrintMACaddress(pAdapterInfo-&gt;Address); } } pAdapterInfo = pAdapterInfo-&gt;Next; } while(pAdapterInfo); } </code></pre> <p>i found that using the ARP function may help with this or since the MAC address is data i may transmit it as a string or raw data but i have idea how to this</p> <p>here is the PrintMAC function:</p> <pre><code> 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); } </code></pre>

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.
