INTERNET_OPEN_TYPE_PRECONFIG means to use the registry proxy entries for the
connection. If you've never run Pocket IE and connected to an Internet
website, there may not be any settings in the registry. (A back-compat.
workaround to support ActiveX controls that don't use CM was added to Pocket
IE that will write them -- you may be seeing this on your PPC 2002 device.)

Technically, you should establish a connection with Connection Manager and
get the proxy settings from the connection manager info struct after
establishing the connection, then pass in these values through
InternetOpen(), rather than using Connection Manager. This will allow
configuration via CM by your application users and be more consistent with
any URL mappings they specify in the CM user interface.

I believe there is a sample of Connection Manager usage in the PPC 2003 SDK.

I am getting an InternetOpenUrl error 12029 ("A connection with the server
could not be established") with code that works fine in Pocket PC 2002 and
HINTERNET hInet = ::InternetOpen(L"testapp",
INTERNET_OPEN_TYPE_PRECONFIG,
NULL, NULL, INTERNET_INVALID_PORT_NUMBER);
if (hInet) {
HINTERNET hURL = ::InternetOpenUrl(hInet,
L"http://10.4.10.81/test.txt", NULL, 0, INTERNET_FLAG_RELOAD, 0);
if (!hURL) {
DWORD dwErr = ::GetLastError();
}
Is there some trick to this now in 2003? It works fine on the other
platforms, and it also downloads the file fine if I type the URL into IE,

it really doesn't make sense to me that it fails. If I use
INTERNET_OPEN_TYPE_DIRECT it works on 2003, but then it won't work with
proxies. Right now I am working around this - if the original call fails,

try again with type "direct". Is this a bug in Pocket PC 2003?
Thanks,
-Derek

But if you have never configured a proxy, shouldn't it default to a direct
connection instead of failing? It did this in 2002, but now fails in 2003
if you have never configured the connection.

Thanks,

BTW, the Internet connection has been configured previously (no proxy) and
IE has been run and used extensively prior to attempting the
InternetOpenUrl().
