Question

I want to retrieve default proxy settings. To do this I use next code:

WINHTTP_PROXY_INFO ProxyInfo;
ZeroMemory( &ProxyInfo, sizeof(ProxyInfo) );

BOOL result = WinHttpGetDefaultProxyConfiguration(&ProxyInfo);

if (result)
{
    //...
}

The function returns TRUE, but in ProxyInfo I have: WINHTTP_ACCESS_TYPE_NO_PROXY and lpszProxy == NULL no matter what settings I put via ProxyCfg.exe->Connections->LAN Settings->Proxy Server. Do you know what I’m doing wrong here?

I tested this code on Win7 64bits machine, but I need it to work in all WinXP+ versions.

I checked libproxy project and there proxy settings are retrieved from registries. Is this method reliable? Is the same registry path for proxy configuration in all Windows versions?

Answer 1

I’ve tried the method used in Chrome and it works fine. Also it should be tested in multiple Windows versions.

WINHTTP_CURRENT_USER_IE_PROXY_CONFIG ProxyInfo;
BOOL result = WinHttpGetIEProxyConfigForCurrentUser(&ProxyInfo);
