I am getting an exception while running the helloworld MFC application. I have created "Desktop Application" and selected "Empty Project" and then added the required code. I also selected "Use MFC as Shared DLL" in project setting. Added CMyApp and CMainWindow class in code. Also added message map. How do I fix this exception?
code: 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
#include <afxwin.h>
#include "Hello.h"
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);
}

actually i missed following statement in Hello.cpp.
CMyApp myApp;
After adding this statement, it works.
