    #include <windows.h> and #include <wininet.h>


    VS c++ 2008

    I am creating a http client application.

    In doing some research I found that I have to include the wininet.h library into my application. I did this and when I compiled I got 283 errors.

    However, I included the header <windows.h> and all thoughs error disppeared.

    I guess that the wininet.h has dependances in the windows.h? And anyone correct if I am wrong about this.

    Another thing, can't I include my headers like this:
    #include <windows>
    #include <wininet>

    As I am writing a programming in C++ I thought I could do away with the .h extensions?

    Many thanks,

    No you cannot
    C++ comes with set of headers that name has no extention, they should be included as

    #include <vector>
    other headers have extention - so you should use the corect name like
    #include <windows.h>
    #include "my_very_special_header.hpp"
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.

    Yes, what vart says is correct. The reason for that is that some header files in C++ have exactly the same name as the ones in C, e.g. string - so to differentiate the C header file string.h from the STL string class file, the latter has no .h on the end.

    Including <string.h> gives you a quite different set of stuff than <string>, and in some cases you may even want both at the same time.

    So all STL headers have no .h [older ones, say in Turbo C do have for example iostream.h, but those are not in the C++ standard set].

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    Download the Windows SDK. You will get your heads & all other necessary files.
    As for networking, may I suggest taking a look at Boost Asio? Perhaps it might just contain some of what you need.

    Outside of your DOS world, your header file is meaningless.
