请教，关于API函数EnumJobs获取打印总页数的问题

[ribut9225]

使用API函数EnumJobs枚举打印作业，其他项目获取对的，就是打印总页数一直为0.请各位大大指点一下，

代码如下：

void fu_PrintJob()
{
	JOB_INFO_1 *pJob1;
	BOOL bRet;
	DWORD dwNeed,dwItems;
	long lRow,lRowCount;
	CString strId,strRq,strSj,strUser,strPrinterName,strDocName,strPageCount;	//日期、时间、使用者、打印机名称、文档名称、总页数
	SYSTEMTIME t_UCT,t_Local;	//UCT时间和本地时间
	int k;
	TIME_ZONE_INFORMATION timeinfo;

	//获取打印作业数量
	bRet = ::EnumJobs(hPrinter,0,0XFFFFFFFF,1,NULL,0,&dwNeed,&dwItems);

	//分配内存空间
	pJob1 = (JOB_INFO_1*)malloc(dwNeed);

	//分别获取打印作业
	bRet = ::EnumJobs(hPrinter,0,0XFFFFFFFF,1,(LPBYTE)pJob1,dwNeed,&dwNeed,&dwItems);

	if(bRet)
	{
		for(k=0;k<dwItems;k++)
		{
			strId.Format("%d",pJob1[k].JobId);	//ID
			t_UCT = pJob1[k].Submitted;
			::GetTimeZoneInformation(&timeinfo);
			::SystemTimeToTzSpecificLocalTime(&timeinfo,&t_UCT,&t_Local);

			strRq.Format("%d-%02d-%02d",
				t_Local.wYear,
				t_Local.wMonth,
				t_Local.wDay
				);	//打印日期
			strSj.Format("%d:%d:%d",
				t_Local.wHour,
				t_Local.wMinute,
				t_Local.wSecond
				);	//打印时间
			strPrinterName.Format("%s",pJob1[k].pPrinterName);	//打印机名称
			strDocName.Format("%s",pJob1[k].pDocument);	//文档名称
			strUser.Format("%s",pJob1[k].pUserName);	//使用者名称
			strPageCount.Format("%d",pJob1[k].TotalPages +1);	//总页数，不知道为何总为0			
			//写入列表
			lRowCount = pList->GetItemCount();
			lRow = pList->InsertItem(lRowCount +1 ,strId);
			//日期
			pList->SetItemText(lRow,1,strRq);
			//时间
			pList->SetItemText(lRow,2,strSj);
			//打印机名称
			pList->SetItemText(lRow,3,strPrinterName);
			//文档名称
			pList->SetItemText(lRow,4,strDocName);
			//所有者
			pList->SetItemText(lRow,5,strUser);
			//总页数
			pList->SetItemText(lRow,6,strPageCount);
		}
	}
	else
	{
		//strText += "枚举打印作业失败";
	}
	//释放内存空间
	free(pJob1);

	//写日志
	fu_WriteLog(strId,strRq,strSj,strPrinterName,strDocName,strUser,strPageCount);
}

typedef struct _JOB_INFO_1 {
  DWORD  JobId;
  LPTSTR pPrinterName;
  LPTSTR pMachineName;
  LPTSTR pUserName;
  LPTSTR pDocument;
  LPTSTR pDatatype;
  LPTSTR pStatus;
  DWORD  Status;
  DWORD  Priority;
  DWORD  Position;
  DWORD  TotalPages;
  DWORD  PagesPrinted;
  SYSTEMTIME Submitted;
} JOB_INFO_1, *PJOB_INFO_1; 

TotalPages 
Specifies how many pages the document contains. This value may be zero if the print job does not contain page delimiting information.

This value may be zero if the print job does not contain page delimiting information.
这个值可能是零，如果打印作业不包含页面划定信息

请问，有没有办法解决这个问题呢？
谢谢
