vc++ excel 写入 与写出数据

1、添加头文件

#include "stdafx.h"

#include "testExcel.h"

#include "testExcelDlg.h"

#include "afxdialogex.h"

#include "CApplication.h"

#include "CRanges.h"

#include "CWorkbook.h"

#include "CWorkbooks.h"

#include "CWorksheet.h"

#include "CWorksheets.h"

#include "CRange.h"

2、初始化com组件

//初始化COM组件

if (!AfxOleInit())

{

AfxMessageBox(_T("无法初始化COM的动态链接库"));

return FALSE;

}

3、关键部分

void CtestExcelDlg::OnBnClickedButtonWrite()

{

// TODO: Add your control notification handler code here

CApplication app;

//创建Excel服务器（启动Excel）

if (!app.CreateDispatch("Excel.Application"))

{

AfxMessageBox("无法启动Excel服务器");

return;

}

//设置Excel的状态

//app.put_Visible(TRUE); //使Excel可见

app.put_UserControl(TRUE); //允许其他用户控制Excel

//vc对Excel的操作

//定义变量

CWorkbooks books;

CWorkbook book;

CWorksheets sheets;

CWorksheet sheet;

CRange range;

LPDISPATCH lpDisp;

COleVariant vResult;

COleVariant covOptional((long)DISP_E_PARAMNOTFOUND,VT_ERROR);

/*________________________

打开已有的Excel文件

books.AttachDispatch(app.get_Workbooks());

//books=app.get_Workbooks();

lpDisp=books.Open("D://1.xls",covOptional,covOptional,covOptional,covOptional,

covOptional,covOptional,covOptional,covOptional,covOptional,covOptional,

covOptional,covOptional,covOptional,covOptional);

*/

//新建一个.xls文件，并写入数据

books.AttachDispatch(app.get_Workbooks());//得到Workbooks

book=books.Add(covOptional);//得到Workbook

//分别向每个单元格添加数据

//Excel2000用函数SetValue（）即可，Excel2003用函数SetValue2（）

sheets=book.get_Worksheets();

sheet=sheets.get_Item(COleVariant((short)1));

range=sheet.get_Range(COleVariant(_T("A1")),covOptional); //单个

range.put_Value2(COleVariant(_T("hanhan")));

m_excelTxt=range.get_Value2();

UpdateData(FALSE); //显示在文本框中

range=sheet.get_Range(COleVariant(_T("B5")),COleVariant(_T("D17"))); //从B5到D17即从B第五行到D第17行矩形区域写东西。

range.put_Value2(COleVariant(_T("Order"))); //添加数据

//range=sheet.get_Range(COleVariant("A1"),covOptional);;//获取A1 range

//range.put_Value2(COleVariant(Date)); //添加数据

//range=sheet.get_Range(COleVariant("B1"),covOptional); //获取B1 Range

//range.put_Value2(COleVariant("Order")); //添加数据

//range=sheet.get_Range(COleVariant("C1"),covOptional);

//range.put_Value2(COleVariant("Amount")); //添加数据

//range=sheet.get_Range(COleVariant("D1"),covOptional);//获取D1 Range

//range.put_Value2(COleVariant("Tax")); //添加数据

// range.AutoFit(); //自动适合尺寸

CString strFile=_T("d:\\8.xlsx");

//将已建的xls文件另存为

// COleVariant covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);

book.SaveAs(COleVariant(strFile),covOptional,covOptional,covOptional,covOptional,

covOptional,0,covOptional,covOptional,covOptional,covOptional,covOptional);

//关闭Excel服务

// COleVariant covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);

book.put_Saved(TRUE); //将Workbook的保存状态设置为已保存，即不让系统提示是否人工保存

range.ReleaseDispatch(); //释放Range对象

sheet.ReleaseDispatch();//释放sheet对象

sheets.ReleaseDispatch(); //释放sheets对象

book.ReleaseDispatch();//释放workbook对象

books.ReleaseDispatch(); //释放workbooks对象

book.Close(covOptional,covOptional,covOptional);//关闭workbook对象

books.Close();

app.Quit();//退出application

app.ReleaseDispatch();//释放application

}
