單純使用C++來處理Office文件並不是一個明智的選擇。如果要用C++的話，請參考如下程式碼：

m_ListCtrl.SetExtendedStyle(LVS_REPORT | LVS_EX_FULLROWSELECT);

CApplication ExcelApp;
CWorkbooks books;
CWorkbook book;
CWorksheets sheets;
CWorksheet sheet;
CRange range;
LPDISPATCH lpDisp = NULL;

//创建Excel 服务器(启动Excel)
if(!ExcelApp.CreateDispatch(_T("Excel.Application"),NULL))
{
    AfxMessageBox(_T("启动Excel服务器失败!"));
    return -1;
}

/*判断当前Excel的版本*/
CString strExcelVersion = ExcelApp.get_Version();
int iStart = 0;
strExcelVersion = strExcelVersion.Tokenize(_T("."), iStart);
if (_T("11") == strExcelVersion)
{
    AfxMessageBox(_T("当前Excel的版本是2003。"));
}
else if (_T("12") == strExcelVersion)
{
    AfxMessageBox(_T("当前Excel的版本是2007。"));
}
else
{
    AfxMessageBox(_T("当前Excel的版本是其他版本。"));
}

ExcelApp.put_Visible(TRUE);
ExcelApp.put_UserControl(FALSE);
