Mình thấy có 1 bài vd trong sách programming MFC như sau:
// file Hello.h
class CMyApp : public CWinApp
{
public:
virtual BOOL InitInstance ();
};
class CMainWindow : public CFrameWnd
{
public:
CMainWindow ();
protected:
afx_msg void OnPaint ();
DECLARE_MESSAGE_MAP ()
};
// file Hello.cpp
#include <afxwin.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);
}
Vậy mà mình copy y chang, bỏ vô VC6++ hoặc VS2008 đều k dùng dc. Nó báo lỗi như sau:
"fatal error C1010: unexpected end of file while looking for precompiled header directive"Bạn nào bít bị sao không? chỉ mình với, huhu
