Wait, are you asking for how to include functions for internet API in windows?

Well, you'll have to research winsocks for internet in windows. Then you'll have to use the import table (see example below) to import the functions you want to use then use invoke or cinvoke to use them. All you have to do is elaborate on the following code based on your reading up of winsocks. The thing with fasm includes is that fasm includes don't do much outside of really useful macros, while functions/procs are in the OS's dlls. MSDN is pretty good at telling you what functions are in what dlls if you lookup the function.

Code:

format PE console
entry main
include 'win32ax.inc'

section '.code' readable executable
main:
cinvoke printf, <"HELLO!", 0> ;printf
cinvoke system, <"PAUSE", 0> ;To hold screen visible.
invoke ExitProcess, 0 ;Close program

section '.idata' readable import data

library kernel, 'kernel32.dll',\  ;kernel is our new identifier/pointer for whatever
                               \  ;is in the string beside it, which is kernel32.dll
        crtdll, 'crtdll.dll'

import kernel, ExitProcess, "ExitProcess" ;ExitProcess is the function we're importing.

import crtdll, printf, 'printf',\
               system, 'system'

There is no real need for winsocks, wininet provides access to HTTP and FTP protocols (among I don't remember how many others). For maximun control you can use sockets but you'll need to implement the protocols yourself so perhaps wininet is fine if your program does not demand special requirements.

I did use wininet before to do an IP address detector but I formatted the HD of the computer where I developed it and also accidentaly erased the backup. Yes I was very happy for my own stupidity!! I even couldn't blame physical media failures this time Sad

Anyway, I did it as kohlrak says, creating the import table by hand and picking the required constants and types from somewhere else (I looked inside the include files of the MASM package if I remember right).

wininet is pretty fine for basic operation indeed, but it's unsuitable for more advanced operations - like, afaik, not being able to override the default max # of per-server connections, unless you change a registry setting (bad!).

It'd probably be easier to just use the import table. Especially because it's the same names you use for getprocaddress, only you have to import a whole extra function just to import a function. If you ask me, it's easier just to import it in the import table.

I can only imagin that there are restrictions on what kind of data you can send as well along with maybe making protocols of your own? I think i recall seeing a library in windows that did all the HTTP work for you.
