我用的是excel2000
首先利用Visual C++ 6.0，建立一個MFC基于對話框的工程項目，共享DLL，Win32平臺。工程名稱ExcelTest。在主對話框中加入一個按鈕，
ID IDC_EXCELTEST
Caption Test Excel
雙擊該按鈕，增加成員函數void CExcelTestDlg::OnExceltest()。
在BOOL CExcelTestApp::InitInstance()中，dlg.DoModal();之前增加代碼：
if (CoInitialize(NULL)!=0)
{
AfxMessageBox("初始化COM支持庫失敗!");
exit(1);
}
在return FALSE; 語句前，加入：
CoUninitialize();
選擇Menu->View->ClassWizade，打開ClassWizade窗口，選擇Add Class->From a type library，選擇D:\Program Files\Microsoft Office\office\Excel9.OLB(D:\Program Files\Microsoft Office\是本機上Microsoft Office 2000的安裝目錄，可根據個人機器上的實際安裝目錄修改)。選擇_Application、Workbooks、_Workbook、Worksheets、_Worksheet、Range，加入新類，分別為_Application、Workbooks、_Workbook、Worksheets、_Worksheet、Range，頭文件Excel9.h，源文件Excel9.cpp。
在ExcelTestDlg.cpp文件的頭部，#include "ExcelTestDlg.h"語句之下，增加 ：
#include "comdef.h"
#include "Excel9.h"
在void CExcelTestDlg::OnExceltest() 函數中增加如下代碼：
void CExcelTestDlg::OnExceltest()
{
_Application ExcelApp;
Workbooks wbsMyBooks;
_Workbook wbMyBook;
Worksheets wssMysheets;
_Worksheet wsMysheet;
Range rgMyRge;
//創建Excel 2000服務器(啟動Excel)

if (!ExcelApp.CreateDispatch("Excel.Application",NULL))
{
AfxMessageBox("創建Excel服務失敗!");
exit(1);
}
//利用模板文件建立新文檔
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，此時,rgMyRge是cells的集合
rgMyRge.AttachDispatch(wsMysheet.GetCells(),true);
//設置1行1列的單元的值
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);
//設置列寬
rgMyRge.SetColumnWidth(_variant_t((long)200));
//調用模板中預先存放的宏
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);
//打印預覽
wbMyBook.SetSaved(true);
ExcelApp.SetVisible(true);
wbMyBook.PrintPreview(_variant_t(false));
//釋放對象
rgMyRge.ReleaseDispatch();
wsMysheet.ReleaseDispatch();
wssMysheets.ReleaseDispatch();
wbMyBook.ReleaseDispatch();
wbsMyBooks.ReleaseDispatch();
ExcelApp.ReleaseDispatch();
