// ExceptionAttacher.cpp Version 1.1
// Copyright © 1998 Bruce Dawson
// This module contains the boilerplate code that you need to add to any
// MFC app in order to wrap the main thread in an exception handler.
// AfxWinMain() in this source file replaces the AfxWinMain() in the MFC
// library.
// Author: Bruce Dawson
// Modified by: Hans Dietrich
// A paper by the original author can be found at:
//#include "stdafx.h"
#include "wx/wxprec.h" // For compilers that support precompilation, includes "wx/wx.h".
#include "ExceptionHandler.h"
// This is the initial entry point into an MFC app. Normally this is in the
// MFC library: mfc\src\winmain.cpp
int AFXAPI AfxWinMain(HINSTANCE hInstance,

int nCmdShow)
// Wrap WinMain in a structured exception handler (different from C++
// exception handling) in order to make sure that all access violations
// and other exceptions are displayed - regardless of when they happen.
// This should be done for each thread, if at all possible, so that exceptions
// will be reliably caught, even inside the debugger.
