问题： 大家帮帮忙，VC转office文档为html的方式？
描述:

在ATL中，如何将word文档等转换为html文档？

---

解决方案1:

读取 word转为byte  再用Response.Charset="GB2312"; 
         Response.AppendHeader("Content-Disposition","attachment;filename=Excel.xls");  
         Response.ContentEncoding = System.Text.Encoding.UTF8; 
         Response.ContentType = "text/html";  
         Response.BinaryWrite();的方式输出

解决方案2:

通过automation操作Word Saveas.
参考下面的代码
////////////////////////////Print Document at background
#include "stdafx.h"
#import "E:\Program Files\Microsoft Office\Office10\MSWORD.OLB" named_guids raw_interfaces_only  rename("ExitWindows", "wordExitWindows")
void wordprint()
{

app.CreateInstance("Word.Application");

app->get_Documents(&docs);
Word::_DocumentPtr doc;
_variant_t vFileName("c:\\a.doc");
_variant_t vOptional((long)DISP_E_PARAMNOTFOUND,VT_ERROR);
_variant_t vTrue(VARIANT_TRUE);
_variant_t vFalse(VARIANT_FALSE);
