When I include the winsock2 header in my msvc++ compiler and try to compile my code it gives my many errors talkin about re-definitions. If i do not include it the code compiles. What do i do to include the header so i can use winsock. "Computers are only as smart as their programers" My Site-> Still working on it.

What else are ou including and/or what are the redifinition errors (ie. what types).

Other than that i am only including windows.h,stdio.hm ddraw.h and a header that I made for ddraw. I will give you some of the errors.

You are probably including windows.h, which includes winsock.h by default. (winsock, not winsock2)

Do one of two things:
#define WIN32_LEAN_AND_MEAN
prior to including windows.h.

Or try including winsock2.h before you include windows.h.

One of those will fix it.

what do I do about this.

You need to include the Winsock library file..

Do this in your code:
#pragma comment(lib, "ws2_32.lib")

Or just use the project settings "Link" tab to include a ref.

-Nate

Also i was just reading this in my book last night that before you include window.h do this

#define _WINSOCKAPI_

or something like that ....at work now.

I''m not sure if that is included in the #deinfe WIN32_LEAN_AND_MEAN

It would be included in winsock2.h so if you include that before windows.h it should be right
