网上搜了一个C脚本，但没有写入到excel的文件中。

#include "apdefap.h"
void OnClick(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName)
{
__object* pExcel = NULL;
HWND handle=NULL;
handle=FindWindow(NULL,"WinCC-运行系统 - ");
pExcel = __object_create("Excel.Application");
pExcel->Visible = 0;
pExcel->Workbooks ->Open ("d:\\report1.xls");
pExcel->Worksheets("sheet1")->Cells(2,2)->Value="2345";
pExcel->ActiveWorkbook->Save();
pExcel->Workbooks->Close();
pExcel->Quit();
__object_delete(pExcel);

}
