vs2010操作 office2010自我笔记
【FAG按顺序添加这些东西】
1.创建一个新的工程，选择mfc application，选择dialog，在advanced features选择automation（这一项我不确定有没有必要，查资料说要选上，我就选上了）
2.创建完工程后，在dialog对话框上右击，选择class wizard（或是ctrl+shift+x)
3.在add class下拉框内选择add class from typelib
4.在add class from下面选择file，然后你的office安装目录下的EXCEL.EXE（我的目录是C:\Program Files (x86)\Microsoft Office\Office14\EXCEL.EXE）
5.在下面添加6个类到我们的工程，（_Application, Worksheets, _Worksheet, Workbooks, _Workbook, Range）注意有的有下划线，别添加错了
【FAG注释掉下面】
把导入的6个类对应的头文件最开始的一句话[注释]
#import "C:\\Program Files (x86)\\Microsoft Office\\Office14\\EXCEL.EXE" no_namespace 【FAG添加下划线】
把Range这个类自动生成的头文件（我这是CRage.h）里面的
VARIANT DialogBox()
VARIANT _DialogBox()
【FAG添加头文件】
//====6个类的头文件================================
#include "CApplication.h"
#include "CRange.h"
#include "CWorkbook.h"
#include "CWorkbooks.h"
#include "CWorksheet.h"
#include "CWorksheets.h"
//====里面定义变量时用到==============================
#include <map>
#include <utility>
using namespace std;
【FAG使用函数】
