文书智能助手

背景

司法、医疗等行业存在着大量的文书，一份文书或者卷宗少则几十页，多则几万页。在查看和检查这些文书时，会遇到大量的信息。当需要查询进一步的详细内容时，往往需要选择一下文字，然后再在各种系统中查询详细的信息。客户就提出了一个思路：“文书智能助手”。文书智能助手：在Word 或者记事本或者其他软件中，使用鼠标框选选中一段文字后，根据“选中的文字”在各种系统中检索数据，自动显示相关的数据项。并可以向Word插入文字和图片内容。

使用说明

启动程序

在文书中使用鼠标框选中文字

根据“选中的文字”在各种系统中检索数据，自动显示相关的数据项。

word监控工具

设计

程序分为主EXE 和DLL

DLL为鼠标HOOK

主EXE在鼠标框选中，获取当前选中的文字，然后进行查询，并显示查询结果。
