Unable to query proxy "Automatically Detect Settings" on windows 7

Question

Hi,

I am trying to capture proxy setting ("Automatically Detect Settings"). My code works on XP and Vista. But it is NOT working on Windows 7

Please see the details of target platform

Windows 7 Enterprise, IE 8.0.7600.16385, Wininet.dll 8.0.7600.16535

Please see the code snippet

INTERNET_PER_CONN_OPTION_LIST List; INTERNET_PER_CONN_OPTION Option[1];

unsigned long nSize = sizeof(INTERNET_PER_CONN_OPTION_LIST); Option[0].dwOption = INTERNET_PER_CONN_FLAGS; List.dwSize = sizeof(INTERNET_PER_CONN_OPTION_LIST); List.pszConnection = NULL; List.dwOptionCount = 1; List.dwOptionError = 0; List.pOptions = Option;

if(!InternetQueryOption(NULL, INTERNET_OPTION_PER_CONNECTION_OPTION, &List, &nSize)) AfxMessageBox(L"InternetQueryOption failed! (%d)\n");

if(Option[0].Value.pszValue != NULL) AfxMessageBox(Option[0].Value.pszValue);

TCHAR a[100]; swprintf(a, L"Flag value is : %d",Option[2].Value.dwValue, 80); AfxMessageBox(a);

But on Windows 7, even if "Automatically Detect Settings" option in IE is checked, the program says that that flag is not set

I tried with WinHttp api also as shown below.

WINHTTP_CURRENT_USER_IE_PROXY_CONFIG stProxyConfig = {0};

WinHttpGetIEProxyConfigForCurrentUser(&stProxyConfig);

if (stProxyConfig.fAutoDetect == TRUE) AfxMessageBox(L"Auto proxy detection enabled"); else AfxMessageBox(L"Auto proxy detection disabled");

On Windows 7, above code also fails to capture the "Automatically Detect Settings" option Any inputs on this is highly appreciated.

Thanks John
