从另外一个窗体程序中控制naviswork中的视图

来源：互联网发布：重生进军网络主播编辑：程序博客网时间：2024/05/20 16:00

近期收到一个朋友的开发需求，要求从一个窗体程序中控制naviswork中的视图，当naviswork为打开时打开naviswork，当naviswork打开时，不再重新打开，并且要实现更换文件的功能。本以为这个需求是需要跨进程方面的技术才能完成的，就想着用sendmessage之类的方法去做，做着做着发现naviswork插件不知道怎么样接受消息。

于是我又重新翻阅了naviswork的开发文档，最终发现了可以使用的api函数，不得不佩服naviswork的强大之处！！！

下面贴一下代码：
