第一步：下载老马哥的从 office和sharepoint 提取出来的注册表和dll http://115.com/file/dpa4qrt2
或者直接安装office和sharepoint2007
第二步：下载我的demo http://files.cnblogs.com/0banana0/OCR.zip
***识别度不是百分之百的 当然需要校准啦 在 编辑器里边修改错误的东西 ！
第三步：发布
本地环境无措 发布到iis包错 “Object hasn't been initialized and can't be used yet”
解决办法：Go to IIS->ApplicatioPools->Default Applicationpool->Identity->custom account->Give the user name and password.
****发布的时候 iis还报一个错：Compiler Error Message: CS0016拒绝访问
解决办法：给c:\windows\temp 加上 network service (只加这个我的不行)和 iis_iusrs(后来加上和这个才行)权限
