VC中如何操作Excel文件？

[RiskyWei]

希望在VC里建立一个新Excel文件，并对其进行数据添加、修改以及删除操作，该如何实现？我导入Excel9.olb类型库后，不知道该怎么操作，请大家指点，最好给出示列代码，谢谢了

OLE程序开发利用（开发EXCEL)
一、首先打开类向导（MFC ClassWizard) 选择Add Class按钮中的 From a type library...找到
Office 目录下的文件 EXCEL9.OLB 并打开。
二、在Confirm Class中的类框中选择你所需的类（EXCEL中的对象）后按OK按钮后依次添加 _Application 、Workbooks 、_Workbook 、Worksheets 、_Worksheet 和　Range类。
三、添加头文件
#include <comdef.h>
#include "excel9.h"
四、代码如下：


void CParameterApp::CreateRepTemp()
{
_Application ExcelApp;
Workbooks wbsMyBooks;
_Workbook wbMyBook;
Worksheets wssMysheets;
_Worksheet wsMysheet;
Range rgMyRge;
CString strSqlStmt;
CString strRepTemplate="c:\\报表\\报表.xlt";

///////////////////////////////////////////////////////////////////////////
CFileFind filefind;
int iFileExist= filefind.FindFile((LPCTSTR)strRepTemplate);

///////////////////////////////////////////////////////////////////////////
if(CoInitialize(NULL)!=0)
{
AfxMessageBox("初始化COM支持库失败！");
exit(1);
}


COleException *e = new COleException;

try
{
if(!ExcelApp.CreateDispatch("Excel.Application.9",e))

throw e;

}

catch (COleDispatchException * e)
{
CString cStr;

if (!e->m_strSource.IsEmpty())
cStr = e->m_strSource + " - ";
if (!e->m_strDescription.IsEmpty())
cStr += e->m_strDescription;
else
cStr += "unknown error";

AfxMessageBox(cStr, MB_OK,
(e->m_strHelpFile.IsEmpty())? 0:e->m_dwHelpContext);

e->Delete();
}

ExcelApp.SetCaption(_T("FARAD 200D 报表模板设置"));
file://得到Workbooks
wbsMyBooks.AttachDispatch(ExcelApp.GetWorkbooks(),true);

if( iFileExist)
{
wbMyBook.AttachDispatch(wbsMyBooks.Add(_variant_t((CString)strRepTemplate)));
file://wbMyBook.SetSaved(true);
file://ExcelApp.GetSaveAsFilename (vtMissing,vtMissing,vtMissing,vtMissing,_variant_t("vtMissing"));
file://wbMyBook.Save ();
file://("xlShared")
file://wbMyBook.SaveAs(_variant_t("d:\\我的工作表.xls"),_variant_t("xlAddIn"),vtMissing,vtMissing,vtMissing,vtMissing,_variant_t(long (1)),_variant_t("xlUserResolution"),vtMissing,vtMissing,vtMissing);
file://运行宏(CString)
ExcelApp.Run(_variant_t("auto_open"),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,vtMissing
);

ExcelApp.SetVisible(true);
ExcelApp.ReleaseDispatch();

}

else
{
CString strSQL=_T("SELECT 报表名称 FROM 报表设置表 ");
PrePareRepName(strSQL);

wbMyBook.AttachDispatch(wbsMyBooks.Add(vtMissing));


file://得到Worksheets
wssMysheets.AttachDispatch(wbMyBook.GetWorksheets(),true);

file://得到sheet1
// wsMysheet.AttachDispatch(wssMysheets.GetItem(_variant_t("sheet1")),true);
wsMysheet.AttachDispatch(wssMysheets.GetItem(_variant_t((long)1)),true);
wsMysheet.SetName(_T("AI"));


file://得到全部Cells，此时,rgMyRge是cells的集合
rgMyRge.AttachDispatch(wsMysheet.GetCells(),true);
file://设置单元的值
strSqlStmt=PrepareSQL("AI历史表");// 获得查询语句
SetTemplateData(&rgMyRge,strSqlStmt);

file://得到所有的列
rgMyRge.AttachDispatch(wsMysheet.GetColumns(),true);
file://设置列宽
rgMyRge.SetColumnWidth(_variant_t((long)15));
file://设置对齐方式
rgMyRge.SetHorizontalAlignment(_variant_t(BYTE(3)));//3:居中

file://得到sheet2
wsMysheet.AttachDispatch(wssMysheets.GetItem(_variant_t((long)2)),true);
wsMysheet.SetName(_T("COUNTER"));


file://得到全部Cells，此时,rgMyRge是cells的集合
rgMyRge.AttachDispatch(wsMysheet.GetCells(),true);

file://设置单元的值
strSqlStmt=PrepareSQL("COUNTER历史表");// 获得查询语句
SetTemplateData(&rgMyRge,strSqlStmt);

file://得到所有的列
rgMyRge.AttachDispatch(wsMysheet.GetColumns(),true);
file://设置列宽
rgMyRge.SetColumnWidth(_variant_t((long)15));
file://设置对齐方式
rgMyRge.SetHorizontalAlignment(_variant_t(BYTE(2)));//2:左对齐


file://得到sheet3
wsMysheet.AttachDispatch(wssMysheets.GetItem(_variant_t((long)3)),true);
wsMysheet.SetName(m_strRepNameArray[0]);
wsMysheet.Activate();
// wsMysheet.SetVisible((long)0);//使sheet3不可视
ExcelApp.SetVisible(true);

file://添加所有的报表表单

AddSheet(wssMysheets, wsMysheet);
file://运行宏
ExcelApp.Run(_variant_t((CString)"宏2"),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,vtMissing
);

wbMyBook.SetSaved(true);
ExcelApp.SetVisible(true);
file://保存文件
wbMyBook.SaveCopyAs(_variant_t((CString)strRepTemplate));

file://释放对象
if(m_strRepNameArray.GetSize()>0)
m_strRepNameArray.RemoveAll();

rgMyRge.ReleaseDispatch();
wsMysheet.ReleaseDispatch();
wssMysheets.ReleaseDispatch();
wbMyBook.ReleaseDispatch();
wbsMyBooks.ReleaseDispatch();
ExcelApp.ReleaseDispatch();
}

CoUninitialize();
