仿百度文档在线阅读文档
最近在做一个在线培训的项目有一个功能需要在线阅服务器上的文档，自己想做一个类似百度问库一样的在线阅读器，找了很多资料最后找到一个很好决绝方案，很多牛人都在博客园里发表了些了一些教程，我按照教程自己做了一个测试能够确实很强大。写的很简单希望能够给能给还在为实现类似百度文库的同学有所帮助。
四步走：
第一步：选择文件上传源文件到服务器
注意：支持office 系列文件 图片文件 图片除了*.BPM 格式的都能够很好的转换
第二部：将上传的文件转换为PDF 文件
注意：在转换为PDF 文件名称中不能够存在空格，存在空格会转换出错
我用的方法是通过正则验证文件名称
Regex reg = newRegex(@"s");
//取消空格后文件名称
uploadFileName =reg.Replace(uploadFileName, "");
第三部：关键的一步将PDF 转换为SWF文件
第四步：将转换后的SWF 文件路径给要显示的控件
网站的基本结构
网站根目录下准备三个文件夹
UploadFiles:用于保存上传文件
UploadFiles>OFFICE:上传的Office 系列文件
UploadFiles>PICTURE：上传的图片文件（再次提示：不支持*.BMP文件）
UploadFiles>PDF:保存第二步转换的PDF 文件
UploadFiles>SWF:保存第四部转后的SWF 文件
JS：保存javascript文件
文件夹内包含两个基本的js文件
Jquery 文件
Flexpape.js 文件
Flexpape 文件
FlexPaperViewer.swf ---界面控件插件
gif2swf.exe ----gif转换器
jpeg2swf.exe ----jpge转换器
pdf2swf.exe ----Pdf转换器
playerProductInstall.swf
png2swf.exe ---png转换器
Flexpape 资源下载地址
支持word、excel、ppt转化为pdf，以及pdf转化为swf文件格式。同时要考虑关于图片文件处理
