error with afxinet.h and windows.h (error c1189)

[cuiky]

hello..
i have an error in my atl application when included file afxinet.h. This application is an OPC Client that is waiting for data from a OPC Server. When data is updated i wake up one thread to connect with a web that return a result of a SQL.
My problem is that when i included file afxinet.h this error appear:

"fatal error c1189: #error: WINDOWS.H already included...."

i'm not included "windows.h"...only my own .h and afxinet.h

what is the solution??


P.D: I'm so sorry for my bad english

If you include any MFC header you do not need any other SDK headers. So remove all includes of winsock2.h and/or windows.h. If you still can't find the error, you should post the full code, and point us to the line where the error happens.

this is my code (only includes):
-> stdafx.h
...
#include "resource.h"
#include <atlbase.h>
#include <atlcom.h>

using namespace ATL;

->OpcClient.cpp
#include "stdafx.h"
#include "OpcClient.h" // Generated throw MIDL
#include "global.h"

-> my_main.cpp
#include "stdafx.h"
#include "OpcClient.h" // Generated throw MIDL
#include "OpcClient_i.c" // Generated throw MIDL
#include "CimplicityConnect.h"
#include "global.h"
#include <fcntl.h>
#include <io.h>

-> CimplicityConnect.cpp
#include "stdafx.h"
#include "OPCDA.h" // Generated throw MIDL
#include "opcda_i.c" // Generated throw MIDL
#include "CimplicityConnect.h"
#include "OPCDataCallback.h"
#include "global.h"

-> OPCDataCallback.cpp
#include "stdafx.h"
#include "OPCDataCallback.h"
#include "global.h"

-> web_access.cpp
#include "stdafx.h"
#include "web_access.h"
#include <afxinet.h> -> this is my problem

when i included afxinet.h in the file web_access.cpp start the error...if comment this line i can't use classes cinternetsesion, chttpconection, etc..

Put #include<afxinet.h> within the stdafx.h itself before all header includes. You may need to shift down this file in headers include (in stdafx.h), if you get some other errors.

i put afxinet.h in stdafx.h and begin to shift down...if #include <afxinet.h> is BEFORE #include <atlbase.h> i have that errors:
--> opcclient.cpp (file with main)
....
class COpcClientModule : public CAtlExeModuleT< COpcClientModule >
{
public :
......
unknow the class CAtlExeModuleT

--> web_access.cpp (file using CInternetSession, etc..)
cerr, endl and cout not declared or not found

if i put #include <afxinet.h> AFTER the initial error of windows.h return
