VC ++ 2010：显示打开的对话框挂起

您好，我已经将VC ++ 6项目转换为VC ++ 2010，并且在显示模态打开文件对话框时遇到错误。

它显示对话框的底部，但顶部缺失，filter也不填充。

标题有公共成员用于存储文件信息：

CString m_strFilePathName; CString m_strFileExtName; 

我的代码显示对话框：

• 获取鼠标hover在其上的控件的名称C＃
• 关于MSDN代码示例，“启用和禁用特权”
• Bitmap.LockBits给出错误的值？
• 比较基于值的COM接口的两个实例
• 如何让Windows上的进程工作目录？

  static TCHAR BASED_CODE szFilter[] = _T("Open Bin File(*.abs)|") _T("Default DataBase File(*.ddf)|") _T("SatCodex File(*.sdx)|") _T("Format Text File(*.txt)"); // TODO: Add your command handler code here CFileDlg fd(TRUE, NULL, "", OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, szFilter); //"Open Bin File(*.abs)|Default DataBase File(*.ddf)|SatCodex File(*.sdx)|Format Text File(*.txt)"); const int c_cMaxFiles = 1; const int c_cbBuffSize = (c_cMaxFiles * (MAX_PATH + 1)) + 1; fd.GetOFN().lpstrFile = m_strFilePathName.GetBuffer(c_cbBuffSize); fd.GetOFN().nMaxFile = c_cbBuffSize; // Dialog hangs on this line: if(fd.DoModal() != IDOK) return; 

诊断返回： 在AliEditor.exe 0x006c69cc第一次机会exception：0xC0000005：访问冲突读取位置0x00000020。

在悬挂模式调用堆栈中断时返回以下信息：

我猜的声明（我不是C ++开发人员）覆盖（fileDlg.cpp）：

一步一步来到同一个（“dlgfile.cpp”）文件中的这一点：

任何人都可以帮我吗？

[更新]现阶段没有人能帮到我，我已经把项目上传到了这里的公共场所。 任何人都可以下载并告诉我什么是错误的，当我点击打开文件？
