    type redefinition?

    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:

    Code:
    struct BLOCK {
    	vector <string> say;
    	vector <string> resp;
    	bool nopunc;
    	int index;
    	BLOCK *next;
    };
    
    
    class cAIBrain {
    ...
    };

    Add this to your header:
    Code:
    #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.

    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
    Code:
    #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..

    Does this help clarify your error some?

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