OLE程序开发利用（开发EXCEL) 之 一

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_strDes cription.IsEmpty())
cStr += e->m_strDes cription;
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
);
