我用的是excel2000
首先利用Visual C++ 6.0，建立一个MFC基于对话框的工程项目，共享DLL，Win32平台。工程名称ExcelTest。在主对话框中加入一个按钮，
ID IDC_EXCELTEST
Caption Test Excel
双击该按钮，增加成员函数void CExcelTestDlg::OnExceltest()。
在BOOL CExcelTestApp::InitInstance()中，dlg.DoModal();之前增加代码：
if (CoInitialize(NULL)!=0)
{
AfxMessageBox("初始化COM支持库失败!");
exit(1);
}
在return FALSE; 语句前，加入：
CoUninitialize();
选择Menu->View->ClassWizade，打开ClassWizade窗口，选择Add Class->From a type library，选择D:\Program Files\Microsoft Office\office\Excel9.OLB(D:\Program Files\Microsoft Office\是本机上Microsoft Office 2000的安装目录，可根据个人机器上的实际安装目录修改)。选择_Application、Workbooks、_Workbook、Worksheets、_Worksheet、Range，加入新类，分别为_Application、Workbooks、_Workbook、Worksheets、_Worksheet、Range，头文件Excel9.h，源文件Excel9.cpp。
在ExcelTestDlg.cpp文件的头部，#include "ExcelTestDlg.h"语句之下，增加 ：
#include "comdef.h"
#include "Excel9.h"
在void CExcelTestDlg::OnExceltest() 函数中增加如下代码：
void CExcelTestDlg::OnExceltest()
{
_Application ExcelApp;
Workbooks wbsMyBooks;
_Workbook wbMyBook;
Worksheets wssMysheets;
_Worksheet wsMysheet;
Range rgMyRge;
//创建Excel 2000服务器(启动Excel)
if (!ExcelApp.CreateDispatch("Excel.Application",NULL))
{
AfxMessageBox("创建Excel服务失败!");
exit(1);
}
//利用模板文件建立新文档
wbsMyBooks.AttachDispatch(ExcelApp.GetWorkbooks(),true);
wbMyBook.AttachDispatch(wbsMyBooks.Add(_variant_t("g:\\exceltest\\MyTemplate.xlt")));
//得到Worksheets
wssMysheets.AttachDispatch(wbMyBook.GetWorksheets(),true);
//得到sheet1
wsMysheet.AttachDispatch(wssMysheets.GetItem(_variant_t("sheet1")),true);
//得到全部Cells，此时,rgMyRge是cells的集合
rgMyRge.AttachDispatch(wsMysheet.GetCells(),true);
//设置1行1列的单元的值
rgMyRge.SetItem(_variant_t((long)1),_variant_t((long)1),_variant_t("This Is A Excel Test Program!"));
//得到所有的列
rgMyRge.AttachDispatch(wsMysheet.GetColumns(),true);
//得到第一列
rgMyRge.AttachDispatch(rgMyRge.GetItem(_variant_t((long)1),vtMissing).pdispVal,true);
//设置列宽
rgMyRge.SetColumnWidth(_variant_t((long)200));
//调用模板中预先存放的宏
ExcelApp.Run(_variant_t("CopyRow"),_variant_t((long)10),vtMissing,vtMissing,
vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,
vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,
vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,
vtMissing,vtMissing,vtMissing,vtMissing,vtMissing,vtMissing);
//打印预览
wbMyBook.SetSaved(true);
ExcelApp.SetVisible(true);
wbMyBook.PrintPreview(_variant_t(false));
//释放对象
rgMyRge.ReleaseDispatch();
wsMysheet.ReleaseDispatch();
wssMysheets.ReleaseDispatch();
wbMyBook.ReleaseDispatch();
wbsMyBooks.ReleaseDispatch();
ExcelApp.ReleaseDispatch();
}
以上内容引自网络。
一下是我自己写的类，将对excel的操作封装了一下：
.h文件：
#include "comdef.h"
#include "excel.h"

{
public:

int GetSheetCount();
bool Open(CString FileName);
ExcelFile();
virtual ~ExcelFile();
