文档管理系统 之一 doc、xls、ppt文档转换成html及System.Runtime.InteropServices.COMException (0x80004005): 360的问题

公司最近需要一套文档管理系统，其实功能很简单，能上传、显示文档，根据权限能否下载、复制、查看

网上也有很多，试用了一下感觉功能都太花哨，都是着重协同办公功能

因为功能不多，所以自己写一个也不费劲，思路如下：

1.先解决文档上传、转换的功能

2.权限管理功能

文档上传转换，将上传的doc、xls、ppt文档转换成html格式，显示时通过js脚本禁止复制

昨天上传转换功能写完后，在本机测试正常，今天发布到服务器后是各种问题，在服务器打开网页都不行，解决到最后可服务器服务器运行了，到客户端上“转换”又报错

具体碰到的问题会在以后的文章中慢慢贴出来，但是今天最大的收获就是“360浏览器 不支持office操作”

文件上传成功后，在转换时出现“System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component. at Microsoft.Office.Interop.PowerPoint.PresentationClass.SaveAs(String FileName, PpSaveAsFileType FileFormat, MsoTriState EmbedTrueTypeFonts) at FileHtml.PPTToHtlm(FileUpload FileUpload1错误，但是用ie，就可以上传并转换

这个问题很纠结，在本机编译成功运行，360浏览器可以转换，不报错，但是在本机一旦访问服务器，就报错，网上没有貌似很好的解决方案，我的解决方案就是，别用360~~~

附带doc、xls、ppt转换html代码

还有一个类是获取文件名及路径的，那个很简单，自己搞搞就出来
