type redefinition?

[the Wookie]

I haven't working on this program in forever, and I compiled it a week ago without any problems.

I opened it today, no changes have been made, and it's giving these errors:

c:\Documents and Settings\Administrator.NABEEL\My Documents\Visual Studio Projects\C++\RELEASE\L!quidBot\AIDLL\cAIBrain.h(15 ): error C2011: 'cAIBrain' : 'class' type redefinition
c:\Documents and Settings\Administrator.NABEEL\My Documents\Visual Studio Projects\C++\RELEASE\L!quidBot\AIDLL\cAIBrain.h(6) : error C2011: 'BLOCK' : 'struct' type redefinition

The code is:

struct BLOCK {
	vector <string> say;
	vector <string> resp;
	bool nopunc;
	int index;
	BLOCK *next;
};


class cAIBrain {
...
};

Add this to your header:

#ifndef HEADER_3D252C71_01B7_49a5_BDF8_A34EB1F241F4
#define HEADER_3D252C71_01B7_49a5_BDF8_A34EB1F241F4

<your header here>

#endif

Replace the GUID with your own*, generated by guidgen.

*) Or use a normal name. But using a GUID ensures 100% code compability.

ah alright, ill see if that works

nope still didn't work, no compile, same errors

Have you tried pressing the execute button, alot of times when I try to compile and build it will give me errors saying that the implementation has changed when I've added something. Pressing the execute will bring up the BUILD new that seems to reload the files in VC++ and all seems well, seems like a VC++ thing or M$ thing cuase something similar happens in MSFrontPage.

ok i told it to clean build, and i compiled fresh.
i get this error now, i have no clue what it means

i havent added/subtracted any header files, and they're all defined in "stdafx.h"

c:\Program Files\Microsoft Visual Studio .NET\Vc7\atlmfc\include\atlctl.h(3284): error C2504: 'IObjectSafety' : base class undefined

#pragma once

#define WIN32_LEAN_AND_MEAN		// Exclude rarely-used stuff from Windows headers
#include <stdio.h>
#include <tchar.h>
#include <stdlib.h>
#include <windows.h>
#include <string.h>
#include <iostream>
#include <vector>

using namespace std;

#include "..\AIDLL\cAIBrain.h"
#include "..\AIDLL\misc.h"

I'm not using MFC or ATL though..

The specified base class was declared but never defined.

This error can be caused by a missing include file or an external base class that was not declared with the extern specifier.

The following is an example of this error:

class A; // error, A is undefined
class A {}; // OK, A is defined
class B : public A {}; // the error is detected here

I'm getting error in a header file for an ATL class that I don't use..I don't have ATL enabled in my project

I don't know, but structs annoy me.. try this. Even though it seems like it's not the answer to the current error, it may help.

typedef struct BLOCK {
	vector <string> say;
	vector <string> resp;
	bool nopunc;
	int index;
	struct BLOCK *next;
};
