Question bout this code

[ForRealzZzZ]

Why doesnt this code work I have been following examples from a book I have and some of the functions in it are undefined by my compiler. I am compiling from Microsoft Visual Studio Ultimate and it still wont pick this one up. I just want to learn MFCs but, its like im programming in another language with no rules.

Heres the cpp
#include <afxwin.h>
#include "header.h"

CMyApp myApp;

BOOL CMyApp::InitInstance()
{
m_pMainWindow = new CMainWindow; //the compiler doesnt seem to like this

m_pMainWnd->ShowWindow(m_nCmdShow); // or the parameter in here
m_pMainWnd->UpdateWindow();
return TRUE;
}

BEGIN_MESSAGE_MAP(CMainWindow, CFrameWnd)
ON_WM_PAINT()
END_MESSAGE_MAP()

CMainWindow::CMainWindow()
{
Create(NULL,_T("The hellow application"));

}

void CMainWindow::OnPaint(){
CPaintDC dc (this);

CRect rect;
GetClientRect (&rect);

dc.DrawText (_T ("Hello, MFC"), -1, &rect,
DT_SINGLELINE | DT_CENTER | DT_VCENTER);

}

and heres the header file


class CMyApp{
public:
virtual BOOL InitInstance();

};

class CMainWindow : public CFrameWnd{
public:
CMainWindow();

protected:
afx_msg void OnPaint();
DECLARE_MESSAGE_MAP()

};

What happens?

Why don't you use standard MFC auto generated code generated by VS 2010 wizard ? That is guaranteed to always work.

@kbw It doesnt run I put comments inside to tell what the compiler took and what it didnt.

@modoran I could do that just to analyze the flow of MFCs and im probably going to ditch the book I have and get petzolds book this was literally one of the first examples in the book.
