如何获取spl文件的页数

问题描述

我正在使用以下代码来填充假脱机程序spl文件（获取emf文件结构）

I'm using the following code to pase spooler spl files (get the emf file structure)

#include "stdafx.h"
#include <windows.h>
#include <winspool.h>
#include <stdio.h>
#include <locale.h>   
#include <tchar.h>
#include <iostream>
using namespace std;

有没有办法用这种方法计算spl文件的页数？

Is there a way to calculate page count of the spl file with this method?
