OLE程序开发利用(开发EXCEL) (转)[@more@]

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
 #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);
 sfilename">file://ExcelApp.GetSaveAsFilename (vtMissing,vtMissing,vtMissing,vtMissing,_variant_t("vtMissing"));
 file://wbMyBook.Save ();
 file://("xlShared")

 file://运行宏(CString)

 }

 else

 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

 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
