Hi guys. While reading about WinHTTP I found one problem I can't solve. It's about IWinHttpRequest::SetProxy method. How to use methods in MASM? I tried to find it in export table of winhttp.dll but it doesn't exist.
Thanks!
it's a COM interface - the masm32 package doesn't have all the necessary includes
we generally make our own for COM
as COM interfaces go, this one's not too bad
this is from the platform sdk, httprequest.idl file
#include "httprequestid.h"
