Hi,
I am trying to compile the first example of Jeff Prosise's book "Programming
Windows with MFC Second Edition" using Visual C++ version 7.1. The example
is very simple and consists of only two files (included below). Following
the book's instructions, I select a Win32 Application with empty project
selected, and add the two files. The compiler lists 2 unresolved externals
as the problem. I think it has to do with the version, b/c the book assumes
you are using the Visual C++ 6 IDE. Does anyone know how to fix the
problem?
Thanks,
cpp
Here are the two files:
hello.h
----------------------
class CMyApp : public CWinApp {
public:
virtual BOOL InitInstance();
};
class CMainWindow : public CFrameWnd {
public:
CMainWindow();
protected:
afx_msg void OnPaint();
DECLARE_MESSAGE_MAP();
};
hello.cpp
--------------------------------
// hello.cpp : Defines the entry point for the console application.
//
#include <afxwin.h>
#include "stdafx.h"
#include "hello.h"
CMyApp myApp;
BOOL CMyApp::InitInstance() {
m_pMainWnd = new CMainWindow;
m_pMainWnd->ShowWindow(m_nCmdShow);
m_pMainWnd->UpdateWindow;
return TRUE;
}
BEGIN_MESSAGE_MAP (CMainWindow, CFrameWnd)
ON_WM_PAINT()
END_MESSAGE_MAP()
CMainWindow::CMainWindow() {
Create (NULL, _T ("The Hello Application"));
}
void CMainWindow::OnPaint() {
CPaintDC dc(this);
CRect rect;
GetClientRect(&rect);
dc.DrawText(_T("Hello, MFC"), -1, &rect, DT_SINGLELINE | DT_CENTER |
DT_VCENTER);
}
