如何使被调用的外部程序成为MDI窗口中的子窗口被管理？

[tonyathome]

比如说，最大化（最小化）、主窗口退出时外部程序也相应地退出。？？？

虽然可以把它放入到MDI中去，可是管理的时候和真正的MdiChild窗口不一样啊。比如我关闭mdi时，却不能同时关闭外部的进程。还望赐教！

可以用API函数setParent A ,B 函数将A窗口放到B里面
再用GetwindowthreadProcess？？得到该窗口的进程句柄
再用TerminateProcess函数结束进程，不过建议使用sendmessage发送关闭消息，给它一个保存工作成果的时间

可是按照正常的mdi child窗口，当其最大化时子窗口的标题栏会显示在父窗口的标题栏中，如果按照采用以上方法，却无法做到。该如何解决呢？
