WinHttpGetIEProxyConfigForCurrentUser function (winhttp.h)
The WinHttpGetIEProxyConfigForCurrentUser function retrieves the Internet Explorer proxy configuration for the current user.
BOOL WinHttpGetIEProxyConfigForCurrentUser( [in, out] WINHTTP_CURRENT_USER_IE_PROXY_CONFIG *pProxyConfig );
[in, out] pProxyConfig
A pointer, on input, to a WINHTTP_CURRENT_USER_IE_PROXY_CONFIG structure. On output, the structure contains the Internet Explorer proxy settings for the current active network connection (for example, LAN, dial-up, or VPN connection).
Returns TRUE if successful, or FALSE otherwise. For extended error information, call GetLastError. Among the error codes returned are the following.
||No Internet Explorer proxy settings can be found.|
||An internal error has occurred.|
||Not enough memory was available to complete the requested operation. (Windows error code)|
In Internet Explorer, the proxy settings are found on the Connections tab of the Tools / Internet Options menu option. Proxy settings are configured on a per-connection basis; that is, the proxy settings for a LAN connection are separate from those for a dial-up or VPN connection. WinHttpGetIEProxyConfigForCurrentUser returns the proxy settings for the current active connection.
This function is useful in client applications running in network environments in which the Web Proxy Auto-Discovery (WPAD) protocol is not implemented (meaning that no Proxy Auto-Configuration file is available). If a PAC file is not available, then the WinHttpGetProxyForUrl function fails. The WinHttpGetIEProxyConfigForCurrentUser function can be used as a fall-back mechanism to discover a workable proxy configuration by retrieving the user's proxy configuration in Internet Explorer.
This function should not be used in a service process that does not impersonate a logged-on user.If the caller does not impersonate a logged on user, WinHTTP attempts to retrieve the Internet Explorer settings for the current service process: for example, the local service or the network service. If the Internet Explorer settings are not configured for these system accounts, the call to WinHttpGetIEProxyConfigForCurrentUser will fail.
