Hi, i was wondering if someone could show me how to log into a website using c++ .net? I want to login to say megaupload.com for example, now i have to code in c++ but how could i do it in managed c++? A link or something would be great, i see many examples of this in c# but not in c++ =/. Is there a way to call this code in .net?<br/> <br/> I have already got my download code working in managed c++(gui) and i can download files from urls but i want to try to be able to get files from sites that require a login to download directly. <br/> <br/> <br/>
