MFC中Excel的导入以及使用步骤

参考地址

在需要对EXCEL表进行操作的类中添加以下头文件：若出现大量错误将其放入stdafx.h中

#include "resource.h"       // 主符号
#include "CWorkbook.h"		//单个工作簿
#include "CRange.h"			//区域类，对Excel大部分操作都需要
#include "CWorkbooks.h"		//管理所有工作簿
#include "CApplication.h"	//Excel应用程序类，管理整个Excel应用

在类中添加以下变量定义：

	//定义Excel中需要的工作簿以及工作表等CApplication m_App;CWorkbooks	m_Books;CWorkbook	m_Book;CWorksheets m_Sheets;CWorksheet	m_Sheet;CRange		m_Range;

然后就可以封装对应函数，以下为打开Excel表的例子，一般包括Excel的读写：

//打开Excel表
int	CExcel_TestApp::OpenExcel(CString FileName)
{HRESULT Hr;//HRESULT函数返回值Hr = CoInitialize(NULL);//CoInitialize告诉Windows以单线程方式创建com对象if (FAILED(Hr)){AfxMessageBox(_T("调用函数失败！"));}LPDISPATCH LpDisp;COleVariant CovOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);if (!m_App.CreateDispatch(_T("Excel.Application"), NULL)){AfxMessageBox(_T("无法启动EXCEL服务器！"));return 0;}m_Books.AttachDispatch(m_App.get_Workbooks);//得到工作簿LpDisp = m_Books.Open(FileName, CovOptional, CovOptional, CovOptional, CovOptional,CovOptional, CovOptional, CovOptional, CovOptional, CovOptional,CovOptional, CovOptional, CovOptional, CovOptional);m_Book.AttachDispatch(LpDisp);//得到单个工作簿m_Sheets.AttachDispatch(m_Book.get_Worksheets);//得到工作簿对应的工作表LpDisp = m_Book.get_ActiveSheet();//得到当前活跃的工作表m_Sheet.AttachDispatch(LpDisp);//获取到表return 1;}

若运行出错，将导入的所有包含#import “C:\Program Files (x86)\Microsoft Office\Root\Office16\EXCEL.EXE” no_namespace头文件中的注释，将CRange.h中的DialogBox改为_DialogBox;

int	MFC_OpenExcel::OpenExcel(CString FileName)
{HRESULT Hr;//HRESULT函数返回值Hr = CoInitialize(NULL);//CoInitialize告诉Windows以单线程方式创建com对象if (FAILED(Hr)){AfxMessageBox(_T("调用函数失败！"));}LPDISPATCH LpDisp;COleVariant CovOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);if (!m_App.CreateDispatch(_T("Excel.Application"), NULL)){AfxMessageBox(_T("无法启动EXCEL服务器！"));return 0;}m_Books=m_App.get_Workbooks();//得到工作簿LpDisp = m_Books.Open(FileName, CovOptional, CovOptional, CovOptional, CovOptional,CovOptional, CovOptional, CovOptional, CovOptional, CovOptional,CovOptional, CovOptional, CovOptional, CovOptional, CovOptional);m_Book.AttachDispatch(LpDisp);//得到单个工作簿m_Sheets=m_Book.get_Worksheets();//得到工作簿对应的工作表LpDisp = m_Book.get_ActiveSheet();//得到当前活跃的工作表m_Sheet.AttachDispatch(LpDisp);//获取到表return 1;}
