问题描述

下面是一个visual studio 2010构建输出，用于生成错误的项目。



1.为什么错误消息：无法找到或打开PDB文件？可以解释一下。解决方案是什么？



2.任何人都可以解释如何解决抛出的以下异常：

MyApp.exe中0x002d757e处的未处理异常：0xC0000005：访问冲突读取位置0xcdcdcdcd。



生成异常的行可在以下位置找到：



Below is a visual studio 2010 build output for a projec generating the "errors".

1. Why the "error" message :Cannot find or open the PDB file?Can any one explain.What is the solution?

2.Can anyone explain how I can resolve the following exception that was thrown:
Unhandled exception at 0x002d757e in MyApp.exe: 0xC0000005: Access violation reading location 0xcdcdcdcd.

The line generating the exception is found in:

BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
	if( !CMDIChildWndEx::OnCreateClient(lpcs,pContext))
	{
		return FALSE;
	}
	
	if(!m_wndSplitter->CreateStatic(this,1,3,WS_CHILD))//This the line generation the exception
	{
		return FALSE;
	}


	//Calculate the size of splitter
	SIZE size;
	CRect rect;
	GetClientRect(&rect);
	size.cx = (rect.right - m_wndSplitter->GetSplitterWidth())/3;
	size.cy = rect.bottom;

	//Set the views
	m_wndSplitter->CreateView(0,0,RUNTIME_CLASS(CDisplayView),size,pContext);
	m_wndSplitter->CreateView(0,1,RUNTIME_CLASS(CClassManagerView),size,pContext);
	m_wndSplitter->CreateView(0,2,RUNTIME_CLASS(CCalcView),size,pContext);
	SetActiveView((CView *)m_wndSplitter->GetPane(1,2));

	//Show the splitter
	m_wndSplitter->ShowWindow(SW_SHOWNORMAL);
	m_wndSplitter->UpdateWindow();

	return TRUE;
}







CChildFrame定义如下：




CChildFrame is defined as shown:

#include"MySplitter.h"

class CChildFrame : public CMDIChildWndEx
{
	DECLARE_DYNCREATE(CChildFrame)
public:
	CChildFrame();

// Attributes
protected:
	CMySplitter *m_wndSplitter;
public:

// Operations
public:
	CMySplitter *GetSplitter() const { return m_wndSplitter;} 
// Overrides
	public:
	virtual BOOL OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext);
	virtual BOOL PreCreateWindow(CREATESTRUCT& cs);

// Implementation
public:
	virtual ~CChildFrame();
#ifdef _DEBUG
	virtual void AssertValid() const;
	virtual void Dump(CDumpContext& dc) const;
#endif

// Generated message map functions
protected:
	DECLARE_MESSAGE_MAP()
};





而MySplitter定义如下：



while MySplitter is defined below:

#pragma once


// CMySplitter

class CMySplitter : public CSplitterWndEx
{
	DECLARE_DYNAMIC(CMySplitter)

public:
	CMySplitter();
	virtual ~CMySplitter();
	int GetSplitterWidth() const { return m_cxSplitter;}
protected:
	DECLARE_MESSAGE_MAP()
};


Please how do I resolve these issues:

推荐答案

Yon从未分配一个值 m_wndSplitter ，因此它指向垃圾。
Yon never assigned a value to m_wndSplitter, hence it is pointing to garbage.
