    <p>So, as you requested Win NT 'solution' only, here is my code.It lists network interfaces with current configured values.</p> <p>Note EnableDHCP registry key value, I think this is the point.</p> <p>As I already mentioned in comment under your question, you need as least simple JNI wrapper.</p> <p>Hope this helps.</p> <p>more info here : <a href="http://support.microsoft.com/kb/314053" rel="nofollow">http://support.microsoft.com/kb/314053</a></p> <pre><code>#include &lt;windows.h&gt; #define NETCARD_ROOT L"SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\NetworkCards" #define TCPIP_ROOT L"SYSTEM\\CurrentControlSet\\services\\Tcpip\\Parameters\\Interfaces" int _tmain(int argc, _TCHAR* argv[]) { //First enumerate all network adapters HKEY hNetCardsKey; LSTATUS lStatus = ERROR_SUCCESS; lStatus = RegOpenKey(HKEY_LOCAL_MACHINE, NETCARD_ROOT, &amp;hNetCardsKey); if(ERROR_SUCCESS == lStatus) { DWORD dwCards = 0L; DWORD dwMaxSubkeyNameLen = 0L; lStatus = RegQueryInfoKey(hNetCardsKey, NULL, NULL, NULL, &amp;dwCards, &amp;dwMaxSubkeyNameLen, NULL, NULL, NULL, NULL, NULL, NULL); if(ERROR_SUCCESS == lStatus &amp;&amp; dwCards) { for(DWORD i = 0; i &lt; dwCards; i++) { TCHAR wszCurrentCardIdxName[MAX_PATH]; wszCurrentCardIdxName[0] = '\0'; lStatus = RegEnumKey(hNetCardsKey, i, wszCurrentCardIdxName, MAX_PATH); if(ERROR_SUCCESS == lStatus) { TCHAR wszAdapterKeyName[MAX_PATH]; wszAdapterKeyName[0] = '\0'; wsprintf(wszAdapterKeyName, L"%s\\%s", NETCARD_ROOT, wszCurrentCardIdxName); HKEY hCardNameKey; lStatus = RegOpenKey( HKEY_LOCAL_MACHINE, wszAdapterKeyName, &amp;hCardNameKey); if(ERROR_SUCCESS == lStatus) { TCHAR wszServiceNameGuid[MAX_PATH]; TCHAR wszAdapterName[MAX_PATH]; DWORD dwSize = sizeof(wszServiceNameGuid); wszServiceNameGuid[0] = '\0'; RegQueryValueEx( hCardNameKey, L"ServiceName", NULL, NULL, (LPBYTE)wszServiceNameGuid, &amp;dwSize); dwSize = sizeof(wszAdapterName); RegQueryValueEx( hCardNameKey, L"Description", NULL, NULL, (LPBYTE)wszAdapterName, &amp;dwSize); OutputDebugStringW(wszServiceNameGuid); OutputDebugStringW(L"\n"); RegCloseKey(hCardNameKey); //Get parameters TCHAR wszCardParamKey[MAX_PATH]; wszCardParamKey[0] = '\0'; wsprintf(wszCardParamKey,L"%s\\%s", TCPIP_ROOT, wszServiceNameGuid); HKEY hParamKey = NULL; lStatus = RegOpenKey( HKEY_LOCAL_MACHINE, wszCardParamKey, &amp;hParamKey); if(ERROR_SUCCESS == lStatus) { DWORD dwEnabledDHCP = 0L; DWORD dwDWSize = sizeof(DWORD); TCHAR wszStaticIP[32]; TCHAR wszDHCPIP[32]; DWORD dwIPSize = sizeof(wszDHCPIP); ZeroMemory(wszDHCPIP, dwIPSize); ZeroMemory(wszStaticIP, dwIPSize); lStatus = RegQueryValueEx( hParamKey, L"EnableDHCP", NULL, NULL, (LPBYTE)&amp;dwEnabledDHCP, &amp;dwDWSize); if(SUCCEEDED(lStatus)) { wprintf_s(L"Adapter : %s [%s] \n\tDHCP : %s\n", wszServiceNameGuid, wszAdapterName, dwEnabledDHCP ?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
