I have a file were I include other files from my program:
#include <windows.h>
#include <stdlib.h>						
#include <gl/gl.h>			
#include <gl/glu.h>

#include "NeHe.h"								
#include "text.h"

#include "CMenu.h"
#include "CController.h"

funny thing is, is that if I keep it how it's written then I get wierd errors from the fstream file. here's the CController:
#include <vector>
#include <windows.h>
#include <fstream>
#include <iomanip>
#include <gl\gl.h>		

#include "SVector2D.h"
#include "defines.h"
#include "CNeuralNet.h"
#include "CData.h"
#include "NeHe.h"
#include "text.h"

using namespace std;

//the program can be in one of three states.

class CController 


  //the neural network
  CNeuralNet*     m_pNet;

  //this class holds all the training data
  CData*          m_pData;
  //the user mouse gesture paths - raw and smoothed
  vector<POINTS> m_vecPath;

  //true if user is gesturing
  bool    m_bDrawing;

  //the highest output the net produces. This is the most
  //likely candidate for a matched gesture.
  double  m_dHighestOutput;

  //the best match for a gesture based on m_dHighestOutput
  int     m_iBestMatch;

  //if the network has found a pattern this is the match
  int     m_iMatch;

  //the raw mouse data is smoothed to this number of points
  int     m_iNumSmoothPoints;

  //                                LPARAM lParam);

  //this temporarily holds any newly created pattern names
  //static string m_sPatternName;



  //call this to train the network using backprop with the current data
  bool TrainNetwork();

  //renders the mouse gestures and relevant data such as the number
  //of training epochs and training error
  void Render();

  //returns whether or not the mouse is currently drawing
  bool Drawing()const{return m_bDrawing;}

  //this is called whenever the user depresses or releases the right
  //mouse button.
  //If val is true then the right mouse button has been depressed so all
  //mouse data is cleared ready for the next gesture. If val is false a
  //gesture has just been completed. The gesture is then either added to
  //the current data set or it is tested to see if it matches an existing
  //The hInstance is required so a dialog box can be created as a child
  //window of the main app instance. The dialog box is used to grab the
  //name of any user defined gesture
  bool Drawing(bool val);

  void LearningMode();

  //call this to add a point to the mouse path
  void AddPoint(POINTS p)
  void SaveNet();
  void Load();


here're save and load:
void CController::SaveNet()
   int count=0;
   vector<SNeuronLayer> netdata = m_pNet->GetNeurons();
   ofstream fout("brain.txt");
   for(int l=0; l<netdata.size(); l++)
     for(int n=0; n<netdata[l].m_vecNeurons.size(); n++)
       for(int w=0; w<netdata[l].m_vecNeurons[n].m_vecWeight.size(); w++)
         fout<<netdata[l].m_vecNeurons[n].m_vecWeight[w]<<" ";

void CController::Load()
 m_Mode = TRAINING;
 m_Mode = ACTIVE;

and I get these errors: 18 C:\Dev-Cpp\Examples\height2\NeHe.cpp from NeHe.cpp C:\Dev-Cpp\include\c++\3.4.2\bits\fstream.tcc In member function `virtual typename std::basic_filebuf<_CharT, _Traits>::int_type std::basic_filebuf<_CharT, _Traits>::underflow()': 277 C:\Dev-Cpp\include\c++\3.4.2\bits\fstream.tcc expected unqualified-id before '(' token ????? What is that?? But if I include the controller after the CMenu:
#ifndef  CMENU_H
#define  CMENU_H

#include <iostream>
#include <stdlib.h>
#include <windows.h>		// Header File For Windows
#include <stdio.h>			// Header File For Standard Input/Output
#include <gl\gl.h>			// Header File For The OpenGL32 Library
#include <gl\glu.h>			// Header File For The GLu32 Library
#include <string.h>
#include <stdarg.h>
#include <vector>

#include "Vector2D.h"
#include "NeHe.h"

#include "text.h"
#include "ortho.h"

using namespace std;

enum   GameState{MainMenu, Playing};
struct SButton{
 SButton(  float h, float w, Vector2D pos, GLint t);
 Vector2D  m_vPosition;
 GLint     tex_id;
 float     hight, width;
 bool      IsPressed();
 void      Render();
class  CMenu{
   //Holds the different states the game can be in 
    GameState m_GameStates;
    vector<SButton> m_vButtons;
    //updates the game menu
    void Update();
    //renders the menu
    void Render();
    //sees if something was pressed
    void ProcessMouse();
//---------------accessor methods
   GameState GetState(){return m_GameStates;}

extern CMenu Menu;

then I get this error: 26 C:\Dev-Cpp\Examples\height2\CMenu.h `Vector2D' has not been declared When I run the controller in a seperate program I get no errors. What is going on here. I had two programs that worked perfectly but when I combine them I get errors? Thanks.

you have a random #endif on the bottom of your controller file. Did you just mis-paste it (skipping the first two lines), or is that possibly your actual error? :).

277 C:\Dev-Cpp\include\c++\3.4.2\bits\fstream.tcc expected unqualified-id before '(' token
You'll probably find that there is a name clash of some kind with the name used just before the '('. Probably a macro with the same name but a different meaning.

On my machine (with the latest dev-c++, and the same include path), that line is:

 __ilen = std::min(__avail, __buflen);

Maybe you defined your own 'min' somewhere, and it's clashing...

windows.h defines macros for min and max. I think there is a way to disable it, but I can't remember it.

My own include policy is to always include the standard library first.

#define NOMINMAX before including windows.h.
