ADO数据库连接Access

创建基于对话框的应用程序ADO,向对话框中添加一个列表视图控件，并为其添加变量m_Grid
第一步：ADO对象的导入
在StdAfx.h头文件中：
// stdafx.h : include file for standard system include files,
//  or project specific include files that are used frequently, bu
//      are changed infrequently
//
#if !defined(AFX_STDAFX_H__D5ADC0DF_B5B2_4973_A035_4F2F1585998F__INCLUDED_)
#define AFX_STDAFX_H__D5ADC0DF_B5B2_4973_A035_4F2F1585998F__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#define VC_EXTRALEAN  // Exclude rarely-used stuff from Windows headers
#include <afxwin.h>         // MFC core and standard components
#include <afxext.h>         // MFC extensions
#include <afxdisp.h>        // MFC Automation classes
#include <afxdtctl.h>  // MFC support for Internet Explorer 4 Common Controls
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h>   // MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT
//ADO对象的导入代码
#import"C:\Program Files\Common Files\System\ado\msado15.dll"
no_namespace rename("EOF","adoEOF")rename("BOF","adoBOF")
//{{AFX_INSERT_LOCATION}}
// Microsoft Visual C++ will insert additional declarations immediately before the previous line.
#endif // !defined(AFX_STDAFX_H__D5ADC0DF_B5B2_4973_A035_4F2F1585998F__INCLUDED_)
第二步：初始化COM环境
BOOL CADOApp::InitInstance()
{
 AfxEnableControlContainer();
 AfxOleInit();//或者::CoInitialize(NULL);
··················
··················
 return FALSE;
}
第三步：连接数据库
