java实现极简单的 TXT小说阅读器(第四版)
来源：互联网 发布：2017网络水军招募 编辑：程序博客网 时间：2024/05/17 02:34
第四版在第三版的基础上增加了
对word文档打开的支持。
主要使用了jacob.jar包以及jacob.dll。
将jacob.dll放入系统目录下。
导入jacob.jar包入工程即可。
MSWordManager类：
public class MSWordManager { // word文档 private Dispatch doc; // word运行程序对象 private ActiveXComponent word; // 所有word文档集合 private Dispatch documents; // 选定的范围或插入点 private Dispatch selection; private boolean saveOnExit = true;
