批量 生成 word 多线程

以下示例将完成批量导出word的功能,由于涉及到批量,为了页面不‘假死’,用到了多线程。至于线程最多能有多少个,网上说没有限制,当时也懒得考虑了,直接多少份就用多少线程。

       导出借用的是水晶报表(Crystal Reports)的现有资源,主要就是稳定,比前一篇导出word的不确定因素相比少了很多。最重要的是,这个页面很复杂,使用了三个子报表,水晶报表的强大之处完全体现出来了。

     如果仔细看,你会发现,不只是导出word,最下面的方法是选择导出的格式,有5种,我所知道常用的,除了Cvs格式都有了,能够满足你的要求了吧。。

        {
