如何解决将窗口停靠在另一个窗口内
| 我有一个Winform应用程序（.NET 2.0 C＃）。从这个应用程序，我想启动另一个进程（另一个winform应用程序）并将其停靠在我的窗口中（或至少使其看起来像是停靠了）。到目前为止，我只能找到有关停靠控件的信息，而不能找到单独进程中的窗口的信息。我的第一个想法是获取窗口的句柄并使用非托管系统调用将窗口的高度/宽度和位置设置到我的停靠区域。但是在开始之前，我想检查一下你们中有没有好人做过类似的事情。我可以访问要停靠的应用程序的源代码，但如果可以避免的话，不希望进行任何更改。我对什么是父应用程序具有完全的编程控制权。有什么建议吗？提前致谢！解决方法
我之前使用的解决方案是将应用程序窗口设置为要停靠在其中的控件的子窗口。
